Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc.
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
Copyright (C)
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see .
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
Copyright (C)
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read

Tools, done right
=================
Guacamole is a LGPLv3 licensed toolkit for creating good command line
applications. Guacamole that does the right things for you and makes writing
applications easier.
.. testsetup::
import guacamole
.. doctest::
>>> class HelloWorld(guacamole.Command):
... """A simple hello-world application."""
... def register_arguments(self, parser):
... parser.add_argument('name')
... def invoked(self, ctx):
... print("Hello {0}!".format(ctx.args.name))
Running it directly is as simple as calling ``main()``:
.. doctest::
>>> HelloWorld().main(['Guacamole'], exit=False)
Hello Guacamole!
0
What you didn't have to do is what matters:
- configure the argument parser
- define and setup application logging
- initialize internationalization features
- add debugging facilities
- write a custom crash handler

Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc.
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library. guacamole-0.9.2/examples/ 0000775 0001750 0001750 00000000000 12560714745 015260 5 ustar zyga zyga 0000000 0000000 guacamole-0.9.2/examples/adder.py 0000775 0001750 0001750 00000005526 12522110401 016675 0 ustar zyga zyga 0000000 0000000 #!/usr/bin/env python

CommandTreeBuilder
==================
Summary
=======
Ingredient for arranging all the :class:`~guacamole.recipes.cmd.Command`
classes into a tree of objects.
Description
===========
The command tree builder ingredient is a part of the command recipe. It is
responsible for instantiating all sub-commands and arranging them into a tree
for other ingredients to work with (most notably the argument parser
ingredient).
The secondary task is to add the *spices* requested by the top-level command to
the bowl. This lets other ingredients act differently and effectively allows
the top-level command to influence the runtime behavior of the whole recipe.
Spices
======
This ingredient is not influenced by any *spices*.
Context
=======
This ingredient adds two objects to the context:
``cmd_tree``
A tree of tuples that describes all of the commands and their sub commands.
``cmd_toplevel``
The top-level command object.
In addition, this ingredient inspects the *spieces* required by the top-level
command and adds them to the bowl.
.. todo::
Add a reference to an article about spices here.
Command Line Arguments
======================
This ingredient is not exposing any command line arguments.
Examples
========
Let's create two examples below. One for a simple command and another for a
hierarchical command. This example will not use the full command recipe, to
focus on the side effects of just the command tree builder ingredient.
Flat Command
------------
We'll need a command object:
.. doctest::
>>> from guacamole.recipes.cmd import Command
>>> class HelloWorld(Command):
... pass
Note that the tree builder is called with an *instance* of the command, not the
class. This allows the top-level command to have a custom initializer, which
might be helpful.
.. doctest::
>>> from guacamole.core import Context
>>> from guacamole.ingredients import cmdtree
>>> ctx = Context()
>>> cmdtree.CommandTreeBuilder(HelloWorld()).added(ctx)
The context now has the ``cmd_toplevel`` object which is just the instance of
the command we've used.
.. doctest::
>>> ctx.cmd_toplevel
Similarly, we'll have a tree of all the commands and their names in ``cmd_tree``:
.. doctest::
>>> ctx.cmd_tree
cmd_tree_node(cmd_name=None, cmd_obj=, children=())
The first element of the tuple is the effective command name. This can be used
to rename a sub-command. Note that typically the ``command.name`` attribute is
used (see :meth:`~guacamole.recipes.cmd.Command.get_cmd_name()`). The second
element is the instance and the last element is a tuple of identical
``cmd_tree_node`` tuples, one for each of the sub-commands. We'll see how that
looks like in the next example.
Nested Commands
---------------
We'll need a few commands for this example. Let's replicate the ``git``, ``git
commit``, ``git stash``, ``git stash pop`` and ``git stash list`` commands.
.. doctest::
>>> from guacamole.recipes.cmd import Command
>>> class StashList(Command):
... pass
>>> class StashPop(Command):
... pass
>>> class Stash(Command):
... sub_commands = (('list', StashList), ('pop', StashPop))
>>> class Commit(Command):
... pass
>>> class Git(Command):
... sub_commands = (('commit', Commit), ('stash', Stash))
Now, let's feed the ``Git`` class to the context.
.. doctest::
>>> from guacamole.core import Context
>>> from guacamole.ingredients import cmdtree
>>> ctx = Context()
>>> cmdtree.CommandTreeBuilder(Git()).added(ctx)
The ``cmd_toplevel`` is as before (the ``Git`` *instance*). Let's look at the
more interesting command tree.
.. doctest::
:options: +NORMALIZE_WHITESPACE
>>> ctx.cmd_tree
cmd_tree_node(cmd_name=None, cmd_obj=,
children=(cmd_tree_node(cmd_name='commit', cmd_obj=,
children=()), cmd_tree_node(cmd_name='stash',
cmd_obj=, children=(cmd_tree_node(cmd_name='list',
cmd_obj=, children=()), cmd_tree_node(cmd_name='pop',
cmd_obj=, children=())))))
Blah, that's mouthful. Let's see particular fragments to understand it better.
.. doctest::
>>> ctx.cmd_tree.children[0].cmd_name
'commit'
>>> ctx.cmd_tree.children[1].cmd_name
'stash'
>>> ctx.cmd_tree.children[1].children[0].cmd_name
'list'
>>> ctx.cmd_tree.children[1].children[1].cmd_name
'pop'
Most of the time you won't have to use this data. Typically, it is consumed by
the argument parser ingredient. Still, if you need it, here it is.
=====================
CommandTreeDispatcher
=====================
Summary
=======
Ingredient for executing the :meth:`~guacamole.recipes.cmd.Command.invoked()`
methods of all the commands that were selected by the user on command line.
Description
===========
This ingredient is responsible for invoking commands. It works during the
dispatch phase of the application life-cycle. Since earlier stages can be
interrupted it is not aways reached. E.g. when the application is invoked with
the ``--help`` argument.
The way this ingredient works is simple. It assumes that the argument parser
creates a specific structure of references to command objects. The structure is
stored in the ``argparse`` name-space object (which is available in
``ctx.args`` after the parsing phase. The structure is a sequence of attributes
``ctx.args.command0``, ``ctx.args.command1``, ``ctx.args.command2``, etc. The
first one, ``ctx.args.command0`` is always present. Subsequent attributes are
present if sub-commands are specified on the command line. For example, keeping
our git sample in mind, the following command::
$ git stash
Will result in ``ctx.args.command0`` instance of the `Git` command and
``ctx.args.command1`` an instance of the `GitStash` command. The dispatcher
ingredient will invoke the ``command0``, look at the return value and then
(most likely) proceed to ``command1`` (N+1 in general).
The way return value is interpreted is interesting. In general, there are three cases:
- None is interpreted as "nothing special happened". In the example above. The
``git stash`` will first call ``Git.invoked()``, see the (default) None and
will proceed to call ``GitStash.invoked()``.
- A generator is interpreted as a context-manager like. This allows, for
example, the ``git`` command to use a context manager in its ``invoked()``
method to provide some managed resource to each sub-command. Note that the
`invoked` method must behave as it if was decorated with
``@functools.contextmanager`` but it must not be actually decorated like
that.
- Any other return value is interpreted as an error code and stops recursive
command dispatch. It will be finally returned from the ``main()`` method or
raised as a ``SystemExit`` exception.
Spices
======
This ingredient is not influenced by any *spices*.
Context
=======
This ingredient does not change the context. It does depend on the ``args``
object that is published by the argument parser ingredient.
Command Line Arguments
======================
This ingredient is not exposing any command line arguments.
Examples
========
Let's see how command invocation works in the few specific examples below.
Single Command
--------------
Let's start with a hello-world command first:
.. doctest::
>>> from guacamole.recipes.cmd import Command
>>> class HelloWorld(Command):
... def invoked(self, ctx):
... print("Hello World")
Let's create the necessary infrastructure for using the dispatcher:
.. doctest::
>>> import argparse
>>> from guacamole.core import Context
>>> from guacamole.ingredients import cmdtree
>>> ctx = Context()
>>> ctx.args = argparse.Namespace()
Now let's run the `HelloWorld` command:
.. doctest::
>>> ctx.args.command0 = HelloWorld()
>>> cmdtree.CommandTreeDispatcher().dispatch(ctx)
Hello World
Success! The print worked and we also got the exit code (None, which is not
printed by the repl).
Next, let's implement the classic UNIX ``false(1)`` command:
.. doctest::
>>> class false(Command):
... def invoked(self, ctx):
... return 1
Now, let's invoke it:
.. doctest::
>>> ctx.args.command0 = false()
>>> cmdtree.CommandTreeDispatcher().dispatch(ctx)
1
One. Also good.
All command line tools return an exit code. If you actually run this command in
the shell you can inspect the return code in several ways (depending on what is
your shell). On Windows that is::
echo %ERRORLEVEL%
And on all other systems, that are mostly using Bash by default::
echo $?
In both cases, you should see ``1`` being printed by those echo statements.
Nested Commands
---------------
Let's expand the Git example to examine the context-manager-like behavior.
.. doctest::
>>> class GitLibrary(object):
... def __enter__(self):
... print("Git initialized")
... return self
... def __exit__(self, *args):
... print("Git finalized")
... def commit(self):
... print("Using git to commit")
>>> class Commit(Command):
... def invoked(self, ctx):
... with GitLibrary() as git:
... git.commit()
>>> class Git(Command):
... sub_commands = (('commit', Commit),)
Now, let's see what dispatch does here:
.. doctest::
>>> ctx.args.command0 = Git()
>>> ctx.args.command1 = Commit()
>>> cmdtree.CommandTreeDispatcher().dispatch(ctx)
Git initialized
Using git to commit
Git finalized
If you have many commands that need to use some shared resource, you may be
tempted to move the initialization to a shared code path. Guacamole allows you
to do this by calling **all** the ``invoked()`` methods of all of the commands
specified on command line.
Let's modify the example to show this. The git library code will say as-is. The
commit and git commands will be changed, to move the initialization code
around.
.. doctest::
>>> class Commit(Command):
... def invoked(self, ctx):
... ctx.git.commit()
>>> class Git(Command):
... sub_commands = (('commit', Commit),)
... def invoked(self, ctx):
... with GitLibrary() as git:
... ctx.git = git
... yield
Now, let's see what dispatch does now:
.. doctest::
>>> ctx.args.command0 = Git()
>>> ctx.args.command1 = Commit()
>>> cmdtree.CommandTreeDispatcher().dispatch(ctx)
Git initialized
Using git to commit
Git finalized
No change, that's running exactly as before but now we can add more commands
without duplicating the relevant code over and over.
.. note::
Here, the finalization will happen even if something bad happens (e.g.
``Commit`` raising an exception). It's not useful often but it can be a way
to use the context manager protocol with commands.

VerboseCrashHandler
===================
Summary
=======
Ingredient for handling crashing commands.
Description
===========
This ingredient mimics the default behavior of python for an uncaught
exception. That is, to print the exception details, the function backtrace and
to exit the process.
Spices
======
This ingredient is not influenced by any *spices*.
Context
=======
This ingredient does not add any objects to the context. This ingredient does
use the context though, to access the crash meta-data. This includes:
``exc_type``
The class of the exception that caused the application to crash.
``exc_value``
The exception object itself.
``traceback``
The traceback object.
.. note::
The three attributes are automatically added by the
:class:`~guacamole.core.Bowl` when something bad happens.
Command Line Arguments

ANSI
====
Summary
=======
Ingredient for working with ANSI Control Codes
Description
===========
The ANSI ingredient exposes ANSI control codes in a simple way. ANSI codes can
be used to control text color and style on compatible terminals.
Linux terminal emulators commonly support a wide subset of control codes.
Particular support differs between the classic Linux console, *Xterm*,
*gnome-terminal* and *konsole* (and the backing libraries). Some features are
supported more widely than others. In particular, the text console is rather
limited and will likely remain so until the systemd-based replacement is
commonly used.
The terminal emulator included in Apple's OS X supports a subset of the
features (3rd party terminal emulators for OS X were not tested, contributions
are welcome). In general you can treat OS X like a poor version of Linux.
The windows command prompt is the most limited environment as it only support
several foreground and background colors and nothing else at all. It also has
issues with Unicode (as in, it doesn't support it at all). On Windows, usage of
ANSI depends on the availability of ``colorama``. Colorama is a third party
library that wraps ``sys.stdout`` and ``sys.stderr``, parses ANSI control codes
and converts them to the corresponding Windows API calls.
Spices
======
This ingredient is not influenced by any *spices*.
Context
=======
This ingredient adds two objects to the context:
``ansi``
An instance of :class:`~guacamole.ingredients.ansi.ANSIFormatter`. The
object is automatically configured (disabled) when the extra control codes
are undesired (stdout not attached to a terminal emulator).
``aprint``
The :meth:`~guacamole.ingredients.ansi.ANSIFormatter.aprint` method, as a
shorthand for ``ctx.ansi.aprint``.
Command Line Arguments
======================
This ingredient is not exposing any command line arguments.
Examples
========
Let's construct a simple example. Note that typically you will use the context
that is provided to you from the
:meth:`~guacamole.recipes.cmd.Command.invoked()` method of a command.
.. doctest::
>>> from guacamole.core import Context
>>> from guacamole.ingredients import ansi
>>> ctx = Context()
>>> ansi.ANSIIngredient(enable=True).added(ctx)
The context now has the ``ansi`` object, which is an instance of
:class:`~guacamole.ingredients.ansi.ANSIFormatter`.
It has some methods and properties that we'll see below but it is also
callable and darn convenient to use.
You can use the ``fg`` and ``bg`` keyword arguments to control the
*foreground* and *background* text color respectively.
.. doctest::
>>> str(ctx.ansi('red on blue', fg='red', bg='blue'))
'\x1b[31;44mred on blue\x1b[0m'
You can use keyword arguments that correspond to *each* of the countless
``sgr_`` constants available in the class
:class:`~guacamole.ingredients.ansi.ANSI`. Here, let's get bold text
using the :attr:`~guacamole.ingredients.ansi.ANSI.sgr_bold` code.
.. doctest::
>>> str(ctx.ansi('bold text', bold=1))
'\x1b[1mbold text\x1b[0m'
In some cases you may want to use different code knowing that the output will
be colorized (e.g. use color codes instead of longer text labels). You can
achieve that by testing :meth`~guacamole.ingredients.ansi.ANSI.is_enabled`.
.. doctest::
>>> # Let's disable the ANSI support for this test
>>> ansi.ANSIIngredient(enable=False).added(ctx)
>>> if ctx.ansi.is_enabled:
... ctx.aprint('!!!', fg='red')
... else:
... ctx.aprint('ALARM')
ALARM
Expressing colors
=================
Guacaomle supports several styles of colors:
- Named colors represented as strings:
* ``"black"``
* ``"red"``
* ``"green"``
* ``"yellow"``
* ``"blue"``
* ``"magenta"``
* ``"cyan"``
* ``"white"``
- Bright variant of named colors (not repeated)
- Indexed colors represented as an integer in range(256):

.. note::
The actual colors behind the string-named colors vary between different
terminal emulators. Sometimes the color is just slightly different.
Sometimes it is just totally unrelated to the one specified in the ANSI

RGB colors are not supported on Windows and OS X. They are only supported
on modern terminal emulators, typically on Linux distributions.

Recipes, Ingredients and Spices
===============================
Guacamole is a framework for creating command line applications. To understand
how to use it, you need to know about the three concepts (recipes, ingredients
and spices). They define how guacamole works (tastes) and they are how you can
make guacamole work for you in new and interesting ways.
Ingredients
-----------
Ingredients are pluggable components that can be added to a guacamole recipe.
They have well-defined APIs and are invoked by guacamole during the lifetime of
the application. You can think of ingredients as of middleware or a fancy
context manager. For an in-depth documentation see the
:class:`~guacamole.core.Ingredient` class. For a list of bundled ingredients
(batteries included) please see `bundled-ingredients`.
**Guacamole uses ingredients to avoid having complex, convoluted core. The core
literally does nothing more than to invoke all ingredients in a given order.
Applications use ingredietns indirectly, through recipes.**
Spices
------
Spices are small, optional bits of taste that can be added along with a given
ingredient. They are just a feature flag with a fancy name. You will see spices
documented along with each ingredient. For many features you will use the sane
defaults that guacamole aims to provide but sometimes you may want to tweak
something. Such elements can be hidden behind an ingredient.
**Guacamole uses spices to offer fixed cusomizability where it makes sense to
do so. Applications say witch spices they wish to use. Spices always enable
non-default behavior.**
Recipes
-------
Recipes define the sequence of ingredients to use for a tasty guacamole. In
reality a recipe is a simple function that returns a list of ingredient
instances to use in a given application.
**Guacamole uses recipes to offer easy-to-use, well-designed patterns for
creating applications. Anyone can create a recipe that uses a set of
ingredients that fit a particular purpose.**
Command?
--------
The :class:`~guacamole.recipes.cmd.Command` class is just a recipe that uses a
set of ingredients. As Guacamole matures, other recipes may be added.
guacamole-0.9.2/docs/usage/philosophy.rst 0000664 0001750 0001750 00000007216 12532100726 020417 0 ustar zyga zyga 0000000 0000000 ====================
Philosophy Statement
====================
The power of Guacamole is based on the simplicity of conventions and sane
defaults. Let's talk about some of the conventions that are followed here.
.. note::
You will see how the philosophy turns into practice in the command
turtorial section.
Defaults Matter
===============
Important things make nice applications and tools behave better than random,
ad-hoc scripts that have no consistency and happily crash on anything
unexpected. Guacamole strives to enable important things that make using
applications pleasant.
By default Guacamole will:
- Expose detailed help and usage messages.
- Use translated messages for everything it does.
- Handle logging for you so that it is useful.
- Handle crashes for you so that users can send feedback.
- Use the right directories in your filesystem.
- Use color-coded information, if supported, for readability.
- Teach you, the developer, if you make a mistake that it can detect.
Some defaults say to turn a feature off. Guacamole uses *spices* to let
developers opt-into those features that they wish to use. You will learn about
spices later in this document. For now just remember that they are equivalent
to feature flags.
Documentation Is Important
==========================
Documentation is the most important thing you can get wrong easily. You can
create perfect tools that do some operation correctly and efficiently but it
will all go to waste if nobody can use your product.
Guacamole encourages developers to write useful documentation. The most basic
form of documentation is the *docstring*. The docstring is powerful. You see it
while writing your code. Other people can see it by various means, using tools
like ``pydoc`` or by reading a document generated with a tool like sphinx.
Guacamole has rich support for documentation. By default, a lot of information
is extracted from your command docstrings. You can reuse all of that, for free,
to create proper manual pages. Quality tools come with documentation and
command line tools use manual pages as the most common, most discoverable means
of learning about a particular program.
Internationalization is Important
=================================
Internationalization is important to many users. While many developers and
system administrators are comfortable with reading English it is strongly
recommended to support localization. Modern software gets this right.
Guacamole supports internationalization by default. Commands can advertise
their gettext domain using the ``gettext_domain`` attribute (see
:meth:`~guacamole.recipes.cmd.Command.get_gettext_domain()` for details).
Guacamole will carefully work with your docstrings to feed them to gettext and
extract the useful bits out.
Commands can mix-and-match different gettext domains without issues. If you are
writing a non-trivial application which is composed of commands coming from
various sources they will all work correctly together.
Convention over Configuration
=============================
Guacamole has a lot of APIs. Most of the time you won't have to work with them.
Guacamole will reuse information that you can provide without defining methods.
This is how the docstrings are used for documentation. This is how you can
define numerous attributes to describe specific features of your commands.
Instead of working with the methods you can just define an item. This has the
advantage that Guacamole can look at your command class and can educate you if
you make a mistake. This is easier to work with than reading through
back-traces or working with type annotations that may or may not be enough to
capture something you want to express.

Usage
=====
.. warning::
Documentation is under construction. For now please refer to the
``examples/`` directory in the source distribution.
There are two layers that you might be interested in.
You can either use the existing recipes, most notably, the Command recipe. This
is the best way to get started with Guacamole and get advantage of the code
that is here already.
The second layer is useful once you start to feel comfortable with the code and
want to get more features or perhaps convert your custom code over to work with
Guacamole.
Both layers are documented below but first read the philosophy statement.

===================
Using Stock Recipes
===================
The Command Recipe
==================
The command recipe contains the distilled, correct behavior for command line
applications. The main face of the command recipe is the
:class:`~guacamole.recipes.cmd.Command` class.
.. note::
Guacamole values conventions. Instead of overriding many of the methods
that comprise the Command class, you can just define a variable that will
take priority. This leads to shorter and more readable code.
Defining commands
-----------------
Let's build a simple hello-world example again:
.. testsetup::
import guacamole
.. doctest::
>>> class HelloWorld(guacamole.Command):
... def invoked(self, ctx):
... print("Hello World!")
The central entry point of each command is the
:meth:`~guacamole.recipes.cmd.Command.invoked()` method. The method is called
once the command is ready to be dispatched. This is what you would put inside
your ``main()`` function, after the boiler-plate code that Guacamole handles
for you. What you do here is up to you.
For now, let's just run our simple example with the convenience method
:meth:`~guacamole.recipes.cmd.Command.main()`. Note that here we're passing
extra arguments to control how the tool executes, normally you would just call
main without any arguments and it will do the right thing.
.. doctest::
>>> HelloWorld().main([], exit=False)
Hello World!
0
For now let's ignore the argument `ctx`. It is extremely handy, as we will see
shortly, but we don't need it yet.
.. note::
This little example is available in the ``examples/`` directory in the
source distribution. The version of Guacaomle packaged in Debian has them
in the directory ``/usr/share/doc/python-guacamole-doc/examples``. As the
directory name implies, you have to install the ``python-guacamole-doc``
package to get them.
Do use the example and play around with it, see how it behaves if you run
it with various arguments. The idea is that Guacamole is supposed to create
*good* command line applications. Good applications do the right stuff
internally. The ``hello-world`` example is trivial but we'll see more of
what is going on internally soon.
Working with arguments & The Context
------------------------------------
Commands typically take arguments. To say which arguments are understood by our
command we need to implement the second method
:meth:`~guacamole.recipes.cmd.Command.register_arguments()`. This method is
called with the familiar :py:class:`argparse.ArgumentParser` instance. You've
seen this code over and over, here you should just focus on configuring the
arguments and options. Guacamole handles the parser for you.
.. doctest::
>>> class HelloWorld(guacamole.Command):
... def register_arguments(self, parser):
... parser.add_argument('name')
... def invoked(self, ctx):
... print("Hello {0}!".format(ctx.args.name))
As you can see, the context is how you reach the command line arguments parsed
by `argparse`. What else is there you might ask? The answer is *everything*.
The context is how *ingredients* can expose useful capabilities to commands.
The command recipe is comprised of several ingredients, as you will later see.
One of those ingredients parsers command line arguments and adds the results to
the context as the ``args`` object.
.. note::
When reading documentation about particular ingredients make sure to see
how they interact with the context. Each ingredient documents that clearly.
Let's run our improved command and see what happens:
.. doctest::
>>> HelloWorld().main(["Guacamole"], exit=False)
Hello Guacamole!
0
No surprises there. We can see that the command printed the hello message and
then returned the exit code ``0``. The exit code is normally passed to the
system so that your application can be scripted.
.. note::
Guacamole will return ``0`` for you if you don't return anything. If you do
return a value we'll just preserve it for you. You can also raise
SystemExit with any value and we'll do the right thing yet again.
This should be all quite familiar to everyone so we won't spend more time on
arguments now. You can read the :py:ref:`argparse-tutorial` if you want.
A small digression, why argparse?
---------------------------------
By default, all command line parsing is handled by :py:mod:`argparse`.
Guacamole doesn't force you to use argparse (nothing really is wired to depend
on it in the core) but the stock set of ingredients do use it. Argparse is
familiar to many developers and by having it by default you can quickly convert
your application code over to guacamole without learning two new things at a
time.
Nesting Commands
----------------
Many common tools expose everything from a top-level command, e.g. ``git
commit``. Here, ``git`` gets invoked, looks at the command line arguments and
delegates the dispatching to the ``git-commit`` command.
All Guacamole commands can be nested. Let's build a quick git-like command to
see how to do that.
.. doctest::
>>> class git_commit(guacamole.Command):
... name = 'commit'
... def invoked(self, ctx):
... print("commit invoked")
>>> class git_log(guacamole.Command):
... def invoked(self, ctx):
... print("log invoked")
>>> class git(guacamole.Command):
... name = 'git'
... sub_commands = (
... (None, git_commit),
... ('log', git_log),
... )
As you see it's all based on declarations. Each command now cares about the
name it is using. Names can be assigned in the ``sub_commands`` list or
individually in each class, by defining the ``name`` attribute.
The name listed in sub_commands takes precedence over the name defined in the
class. Here, the ``git_log`` command doesn't define a ``name`` so we provide
one explicitly as the first element of the pair, as sequence of which is stored
in ``sub_commands``.
.. note::
Behind the scenes Guacamole actually calls a number of methods for
everything. See :meth:`~guacamole.recipes.cmd.Command.get_sub_commands()`
and :meth:`~guacamole.recipes.cmd.Command.get_cmd_name()` for the two used
here. There are *many* more methods though.
Let's invoke our fake git to see how that works now:
.. doctest::
>>> git().main(["commit"], exit=False)
commit invoked
0
>>> git().main(["log"], exit=False)
log invoked
0
So far everything behaves as expected. Let's see what happens if we run
something that we've not coded:
.. doctest::
>>> git().main(["status"], exit=False)
2
This won't fit the *doctest* above (it's printed on stderr) but in reality the
application will also say something like this::
usage: git [-h] {commit,log} ...
setup.py: error: invalid choice: 'status' (choose from 'commit', 'log')
.. note::
Technically the :class:`~guacamole.recipes.cmd.Command` class has numerous
methods. Most of those methods are of no interest to most of the
developers. Feel free to read the API reference later if you are
interested.

Installation
============
The recommended installation method varies per platform. In general
``pip``-based installs work everywhere but it is recommended to use other
methods if possible.
Linux Distributions
===================
Debian (and derivatives)
------------------------
Install either ``python-guacamole`` or ``python3-guacamole`` (preferred) using
your preferred package manager front-end. An off-line copy of the documentation
is available in the ``python-guacamole-doc`` package. The same package includes
all of the bundled examples.
.. note::
The version of Guacamole available in Debian might not be the most recent
version but it was manually reviewed by Debian maintainers. The Debian
archive contains cryptographically strong integrity and security
guarantees. This method of installation is more trustworthy (and harder to
attack) than the one used by pip.
Fedora (and derivatives)
------------------------
Currently there is no version of Guacamole packaged and available for Fedora. A
*copr* repository might be created if there is demand. Proper integration into
the Fedora archive is on the roadmap but was not attempted at this time.
Other distributions
-------------------
There are no other packages as of this writing. Please contribute one if you
can. See the :ref:`contributing` for details.
Other platforms
===============
At the command line run::
$ pip install guacamole
.. note::
This section applies to all versions of Windows and OS X.

~~~~~~~~~~~~~~~~~~~
Guacamole could always use more documentation, whether as part of the
official Guacamole docs, in docstrings, or even on the web in blog posts,
articles, and such.
Submit Feedback
~~~~~~~~~~~~~~~
The best way to send feedback is to file an issue at
https://github.com/zyga/guacamole/issues.
If you are proposing a feature:
* Explain in detail how it would work.

* Remember that this is a volunteer-driven project, and that contributions
are welcome :)
Get Started!
------------
Ready to contribute? Here's how to set up `guacamole` for local development.
1. Fork the `guacamole` repo on GitHub.
2. Clone your fork locally::
$ git clone git@github.com:your_name_here/guacamole.git
3. Install your local copy into a virtualenv. Assuming you have
virtualenvwrapper installed, this is how you set up your fork for local
development::
$ mkvirtualenv guacamole
$ cd guacamole/
$ python setup.py develop
4. Create a branch for local development::
$ git checkout -b name-of-your-bugfix-or-feature
Now you can make your changes locally.
5. When you're done making changes, check that your changes pass flake8 and
the tests, including testing other Python versions with tox::
$ flake8 guacamole
$ python setup.py test
$ tox
To get flake8 and tox, just pip install them into your virtualenv.
6. Commit your changes and push your branch to GitHub::
$ git add .
$ git commit -m "Your detailed description of your changes."
$ git push origin name-of-your-bugfix-or-feature
7. Submit a pull request through the GitHub website.
Pull Request Guidelines
-----------------------
Before you submit a pull request, check that it meets these guidelines:
1. The pull request should include tests.
2. If the pull request adds functionality, the docs should be updated. Put
your new functionality into a function with a docstring, and add the
feature to the list in README.rst.
3. The pull request should work for Python 2.7, 3.2, 3.3, and 3.4, and for
PyPy. Check https://travis-ci.org/zyga/guacamole/pull_requests
and make sure that the tests pass for all supported Python versions.
Tips
----
To run a subset of tests::
$ python -m unittest guacamole.test_core
(Where guacamole.test_core is the module with tests you want to run)

Tools, done right
=================
Guacamole is a LGPLv3 licensed toolkit for creating good command line
applications. Guacamole that does the right things for you and makes writing
applications easier.
.. testsetup::
import guacamole
.. doctest::
>>> class HelloWorld(guacamole.Command):
... """A simple hello-world application."""
... def register_arguments(self, parser):
... parser.add_argument('name')
... def invoked(self, ctx):
... print("Hello {0}!".format(ctx.args.name))
Running it directly is as simple as calling ``main()``:
.. doctest::
>>> HelloWorld().main(['Guacamole'], exit=False)
Hello Guacamole!
0
What you didn't have to do is what matters:
- configure the argument parser
- define and setup application logging
- initialize internationalization features
- add debugging facilities
- write a custom crash handler
Features
========
* Free software: LGPLv3 license
* Documentation: https://guacamole.readthedocs.org.
* Create command classes and run them from command line.
* Group commands to create complex tools.
* Use recipes, ingredients and spices to customize behavior

Recipe for using guacamole to run commands.
This module contains sock recipes for guacamole. Stock recipes allow
application developers to use use simple-to-understand design patterns to get
predictable runtime behiavior.
Currently, guacamole ships with two such recipes, for creating simple commands
and for creating hierarhical command groups. They are captured by the
:class:`Command` and :class:`Group` classes respectively.

APIs for guacamole add-on developers.
This module contains the public APIs for add-on developers. Add-ons (or
plug-ins) for guacamole are called **ingredients**. The :class:`Ingredient`
class contains a description of available add-on methods.
Ingredients are somewhat similar to Django middleware as they can influence the
execution of an application across its life-cycle. All of core guacamole
features are implemented as ingredients. Developers are encouraged to read core
ingredients to understand how to formulate their own design.
Ingredient APIs are *public*. They will be maintained for backwards
compatibility. Since Guacamole doesn't automatically enable any third-party
ingredients, application developers that wish to use them need to use the
:mod:`guacamole.core` module to create their own guacamole out of available
ingredients. Ingredient developers are recommended in documenting how to use
each ingredient this way.
In addition this module contains the public APIs for creating custom mixes of
guacamole. A custom mix begins with a :class:`~guacamole.core.Bowl` with any
number of :class:`~guacamole.core.Ingredient` objects added.
If you are familiar with the :class:`~guacamole.recipes.cmd.Command` class you
should know that they are using the recipe system internally. They refer to
pre-made recipes that put particular ingredients into the bowl for a ready
dish.
If you wish to build a custom experience on top of guacamole, please provide a
new recipe class. Recipes are how applications should interact with any
guacamole mixtures.

"""
Ingredient for using argparse to parse command line arguments.
This ingredient uses the following Ingredient methods:
- ``build_early_parser()``
- ``preparse()``
- ``build_parser()``
- ``parse()``
The main parser is constructed in, unsurprisingly, the
:meth:`build_parser()` method and stored in the context as ``parser``.
Other ingredients can be added *after* the ``ParserIngredient`` and can
extend the available arguments (on the root parser) by using standard
argparse APIs such as ``parser.add_argument()`` or
``parser.add_argument_group()``. This parser is used to handle all of
command line in the :meth:`parse()` method.
While most users won't concern themselves with this design decision, there
is also a second parser, called the *early parser*, that is used to
*pre-parse* the command line arguments. This can be used as a way
to optimize subsequent actions as, perhaps, knowing which commands are
going to be invoked there will be no need to instantiate and prepare *all*
of the commands in the command tree.
Currently this feature is not used. To take advantage of this knowledge you
can look at the ``context.early_args`` object which contains the result of
parsing the command line with the *early parser*. The early parser is a
simple parser consisting of ``--help``, ``--version`` (if applicable) and
*rest*. The *rest* argument can be used as a hint as to what is coming next
(e.g. if it matches a name of a command we know to exist)
After parsing is done the results of parsing the command line are stored in
the ``context.args`` attribute. This is commonly accessed by individual
commands from their ``invoke()`` methods.

Guacamole -- command line applications that suck less.
Guacamole is a flexible, modular system for creating command line applications.
Guacamole comes with built-in support for writing command line applications
that integrate well with the running system. A short list of supported features
(ingredients) includes:
- handling flat and hierarchical commands
- hassle-free crash detection
- hassle-free logging
- internationalization and localization
The guacamole ingredient system allows for third party add-ons. Please read the
add-on developer guide for details.
.. note::
Guacamole supports Python 2.7 and Python 3.2, 3.4 and 3.5. Other versions
are not tested extensively. Versions earlier than 2.7 are not supported and
won't be. Applications that still need to support the end-of-life Python
2.x release series are encouraged to update to Python 2.7.
Lower-level classes can be found in the :mod:`guacamole.core` and
:mod:`guacamole.recipes` modules. Add-on developers should use those modules
exclusively. All other APIs are considered private.

"""
Part of guacamole.
Ingredients are a mechanism for inserting functionality into Guacamole.
The sequence of calls to ingredient methods is as follows:
- :meth:`added()`
The added method is where an ingredient can advertise itself to other
ingredients that it explicitly collaborates with.
- :meth:`preparse()`
The preparse method is where ingredients can have a peek at the command
line arguments. This can serve to optimize further actions. Essentially
guacamole allows applications to parse arguments twice and limit the
actions needed to do that correctly to the essential minimum required.
- :meth:`early_init()`
The early initialization method can be used to do additional
initialization. It can take advantage of the fact that the whole command
line arguments are now known and may have been analyzed further by the
preparse method.
- :meth:`parse()`
The parse method is where applications are expected to fully understand
command line arguments. This method can abort subsequent execution if
arguments are wrong in in some way. After parsing command line arguments
the application should be ready for execution.
- :meth:`late_init()`
The late initialization method mimics the early initialization method but
is called after parsing all of the command line arguments. Again, it can be
used to prepare addiotional resources necessary for a given application.
- :meth:`dispatch()`
The dispatch method is where applications execute the bulk of their
actions. Dispatching is typically done with one of the standard
ingredients which will locate the appropriate method to call into the
application.
Depending on the outcome of the dispatch (if an exception is raised or not)
one of :meth:`dispatch_succeeded()`` or :meth:`dispatch_failed()` is
called.
- :meth:`shutdown()`
This is the last method called on all ingredients.
Each of those methods is called with a context argument
(:class:`Context:`). A context is a free-for-all environment where
ingredients can pass data around. There is no name-spacing. Ingredients
should advertise what they do with the context and what to expect.

Tools, done right
=================
Guacamole is a LGPLv3 licensed toolkit for creating good command line
applications. Guacamole that does the right things for you and makes writing
applications easier.
.. testsetup::
import guacamole
.. doctest::
>>> class HelloWorld(guacamole.Command):
... """A simple hello-world application."""
... def register_arguments(self, parser):
... parser.add_argument('name')
... def invoked(self, ctx):
... print("Hello {0}!".format(ctx.args.name))
Running it directly is as simple as calling ``main()``:
.. doctest::
>>> HelloWorld().main(['Guacamole'], exit=False)
Hello Guacamole!
0
What you didn't have to do is what matters:
- configure the argument parser
- define and setup application logging
- initialize internationalization features
- add debugging facilities
- write a custom crash handler
