Which one should you use? Why choose? With pokrok, you can access a number of popular packages using a single consistent interface. With this approach, you can: 1. Allow your users to configure their favorite package. 2. Switch from one progress meter implementation to another without having to rewrite any code. 3. Use any supported package optimally, for the most common use cases, without having to read the manual. # Types of progress meters Generally, a progress meter is a visual representation of the progress of a task. The two most common types of progress meters are: * Progress bar - shows progress of a task of known size, advancing steadily from 0 to 100% complete. * Spinner - shows that there is progress, but with no indication of how much of the task is remaining (because the size of the task is unknown). In addition to the progress indicator, each type of progress meter may be accompanied by other information such as elapsed time and estimated time remaining. We call the different aspects of the progress bar display 'widgets.' Pokrok provides a simple API for displaying progress bars and spinners. The actual work is done by any one of many available progress bar packges in python. For each package, a sensible default display is provided. In addition, high-level configuration options are provided for limited customization of the bar/spinner display without having to know the details of the underlying progress bar/spinner implementation. Finally, access to the fine-grained configuration of the underlying package is provided for those that want it. # Installation Pokrok requires python 3.4+. ```bash pip install pokrok ``` This will install pokrok, but for pokrok to be useful it also needs at least one supported progress bar package to be installed. Some examples are: * tqdm * halo # Examples ```python import pokrok as pk import random # Configure pokrok with a list of your preferred progress bars, in order. Set # exclusive=True to prevent pokrok from using any other packages but the ones # you specify. pk.set_plugins(['tqdm', 'halo'], exclusive=True) # Show progress while iterating 100 times numbers = [random.random() for i in pk.progress_range(100)] # Show progress while iterating over lines in a file for line in pk.progress_file('foo.txt', 'rt'): print(line) # Show progress while iterating over an arbitrary iterable. Since the # `progress_iter` function doesn't know the number of items over which # it is iterating, it must be told explicitly using the 'size' argument. def generate_random(n): for i in range(n): yield random.random() for num in pk.progress_iter(generate_random(100), size=100): print(num) # Get a progress context manager bar you can control manually. with pk.progress_meter(size=100) as bar: for i in range(1000): # Only update progress every 10 cycles if i % 10 == 0: bar.increment() print(i) # Or take full control. bar = pk.progress_meter(size=100) bar.start() for i in range(1000): # Only update progress every 10 cycles if i % 10 == 0: bar.increment() print(i) bar.finish() ``` # Configuration If you'd just like to use the default implementations provided by whatever plugin is selected, you don't need to do anything. However, if you want to take some control over the progress bar/spinner display, you have two options. ## High-level configuration Pokrok defines a set of widgets that are commonly provided by progress meter packages. Widgets are combined into "styles." A style is simply a listing of the desired widgets (left-to-right). Separate widget lists can be provided for sized (i.e. progress bar) versus unsized (i.e. spinner) progress meters. There is a global default style, and any number of named styles can be created. When a style is used to create a progress meter, the underlying progress meter library will do its best to provide the desired display; any widgets it cannot provide are ignored silently. ```python # Global configuration from pokrok import set_styles, progress_meter, Style, Widget as w set_styles( default=Style(sized=[w.BAR, w.ETA], unsized=[w.SPINNER, w.ELAPSED]), kitchen_sink=Style([w.SPINNER, w.BAR, w.ELAPSED, w.ETA]) ) # Use a pre-defined configuration bar = progress_meter(size=100, style='kitchen_sink') # Per-progress meter configuration bar = progress_meter(size=100, style=Style([w.ETA, w.ELAPSED, w.BAR])) ``` ## Fine-grained configuration **NOTE: the fine-grained configuration support described below is still being implemented.** You can also specify configuration options for each of the progress meter packages you want to support. All configuration options can be set via a JSON configuration file, '.pokrok'. Pokrok looks for this file by default in the following places (in order): 1. ~/pokrok.json 2. ./pokrok.json By default, the first file discovered is loaded and used for configuration. You can override or supplement this behavior using the `configure()` function. Configuration options for each package can be specified in a dict via a keyword argument to `configure()`. If a file and keyword arguments are given together, the options in the file override the keyword arguments (i.e. the keyword arguments are treated as defaults for options that are not specified in the file). To override this behavior, call the `configure()` function twice - first with the file, then with the keyword arguments. ```python import pokrok as pk # Execute the default configuration behavior (this happens by default when the # first progress meter is requested, so while you can call the configure() # function explicitly, you don't have to unless you intend to override any options. pk.configure() # Load the configuration from an alternate file path, and override options for the # tqdm and halo libraries. pk.configure(filename='~/pokrok.json') pk.configure( tqdm=dict(ncols=100, unit='sec'), halo=dict(spinner='dots', color='blue') ) ``` # Plugins Plugins are created by implementing the pokrok API. The easiest way to do this is to extend the base classes in pokrok.plugins. For example, here is the implementation of the built-in `tqdm` module: ```python from pokrok.plugins import ( DefaultProgressMeterFactory, BaseProgressMeter, Status) from pokrok.styles import Style, Widget class TqdmProgressMeterFactory(DefaultProgressMeterFactory): def __init__(self): style_superset = Style([ Widget.BAR, Widget.ETA, Widget.ELAPSED, Widget.SPINNER ]) super().__init__('tqdm', TqdmProgressMeter, style_superset) def iterate( self, iterable, size=None, widgets=None, desc=None, start=None, **kwargs): if self._load_module(): return self._module.tqdm( iterable, total=size, desc=desc, initial=start or 0, **kwargs) else: return iterable class TqdmProgressMeter(BaseProgressMeter): def __init__(self, mod, size, style, desc, start, **kwargs): super().__init__(size) self.tqdm = mod.tqdm( total=size, desc=desc, initial=start or 0, **kwargs) def finish(self): super().finish() self.tqdm.close() def increment(self, n=1): self._check_status(Status.STARTED) self.tqdm.update(n) ``` To make the plugin visible to pokrok, add an entry point in your setup.py. For example, here is how the built-in TQDM plugin is configured: ```python entry_points=""" [pokrok] tqdm=pokrok.plugins.tqdm:TqdmProgressMeterFactory """ ``` # TODO * Add manual and automatic error handling (with callback to the plugin). * Implement file-based configuration. * Add support for additional packages: * progressbar2 * Add multi-progress bar support (e.g. for multithreading/multiprocessing) * https://pypi.python.org/pypi/progrock/0.3.1 pokrok-0.2.0/pokrok/000077500000000000000000000000001332213150700143205ustar00rootroot00000000000000pokrok-0.2.0/pokrok/__init__.py000066400000000000000000000163241332213150700164370ustar00rootroot00000000000000"""Main pokrok API.

The Versioneer ============== * like a rocketeer, but for versions! * https://github.com/warner/python-versioneer * Brian Warner * License: Public Domain * Compatible With: python2.6, 2.7, 3.2, 3.3, 3.4, 3.5, 3.6, and pypy * [![Latest Version] (https://pypip.in/version/versioneer/badge.svg?style=flat) ](https://pypi.python.org/pypi/versioneer/) * [![Build Status] (https://travis-ci.org/warner/python-versioneer.png?branch=master) ](https://travis-ci.org/warner/python-versioneer) This is a tool for managing a recorded version number in distutils-based python projects. The goal is to remove the tedious and error-prone "update the embedded version string" step from your release process. Making a new release should be as easy as recording a new tag in your version-control system, and maybe making new tarballs. ## Quick Install * `pip install versioneer` to somewhere to your $PATH * add a `[versioneer]` section to your setup.cfg (see below) * run `versioneer install` in your source tree, commit the results ## Version Identifiers Source trees come from a variety of places: * a version-control system checkout (mostly used by developers) * a nightly tarball, produced by build automation * a snapshot tarball, produced by a web-based VCS browser, like github's "tarball from tag" feature * a release tarball, produced by "setup.py sdist", distributed through PyPI Within each source tree, the version identifier (either a string or a number, this tool is format-agnostic) can come from a variety of places: * ask the VCS tool itself, e.g. "git describe" (for checkouts), which knows about recent "tags" and an absolute revision-id * the name of the directory into which the tarball was unpacked * an expanded VCS keyword ($Id$, etc) * a `_version.py` created by some earlier build step For released software, the version identifier is closely related to a VCS tag. Some projects use tag names that include more than just the version string (e.g. "myproject-1.2" instead of just "1.2"), in which case the tool needs to strip the tag prefix to extract the version identifier. For unreleased software (between tags), the version identifier should provide enough information to help developers recreate the same tree, while also giving them an idea of roughly how old the tree is (after version 1.2, before version 1.3). Many VCS systems can report a description that captures this, for example `git describe --tags --dirty --always` reports things like "0.7-1-g574ab98-dirty" to indicate that the checkout is one revision past the 0.7 tag, has a unique revision id of "574ab98", and is "dirty" (it has uncommitted changes. The version identifier is used for multiple purposes: * to allow the module to self-identify its version: `myproject.__version__` * to choose a name and prefix for a 'setup.py sdist' tarball ## Theory of Operation Versioneer works by adding a special `_version.py` file into your source tree, where your `__init__.py` can import it. This `_version.py` knows how to dynamically ask the VCS tool for version information at import time. `_version.py` also contains `$Revision$` markers, and the installation process marks `_version.py` to have this marker rewritten with a tag name during the `git archive` command. As a result, generated tarballs will contain enough information to get the proper version. To allow `setup.py` to compute a version too, a `versioneer.py` is added to the top level of your source tree, next to `setup.py` and the `setup.cfg` that configures it. This overrides several distutils/setuptools commands to compute the version when invoked, and changes `setup.py build` and `setup.py sdist` to replace `_version.py` with a small static file that contains just the generated version data. ## Installation See [INSTALL.md](./INSTALL.md) for detailed installation instructions. ## Version-String Flavors Code which uses Versioneer can learn about its version string at runtime by importing `_version` from your main `__init__.py` file and running the `get_versions()` function. From the "outside" (e.g. in `setup.py`), you can import the top-level `versioneer.py` and run `get_versions()`. Both functions return a dictionary with different flavors of version information: * `['version']`: A condensed version string, rendered using the selected style. This is the most commonly used value for the project's version string. The default "pep440" style yields strings like `0.11`, `0.11+2.g1076c97`, or `0.11+2.g1076c97.dirty`. See the "Styles" section below for alternative styles. * `['full-revisionid']`: detailed revision identifier. For Git, this is the full SHA1 commit id, e.g. "1076c978a8d3cfc70f408fe5974aa6c092c949ac". * `['date']`: Date and time of the latest `HEAD` commit. For Git, it is the commit date in ISO 8601 format. This will be None if the date is not available. * `['dirty']`: a boolean, True if the tree has uncommitted changes. Note that this is only accurate if run in a VCS checkout, otherwise it is likely to be False or None * `['error']`: if the version string could not be computed, this will be set to a string describing the problem, otherwise it will be None. It may be useful to throw an exception in setup.py if this is set, to avoid e.g. creating tarballs with a version string of "unknown". Some variants are more useful than others. Including `full-revisionid` in a bug report should allow developers to reconstruct the exact code being tested (or indicate the presence of local changes that should be shared with the developers). `version` is suitable for display in an "about" box or a CLI `--version` output: it can be easily compared against release notes and lists of bugs fixed in various releases. The installer adds the following text to your `__init__.py` to place a basic version in `YOURPROJECT.__version__`: from ._version import get_versions __version__ = get_versions()['version'] del get_versions ## Styles The setup.cfg `style=` configuration controls how the VCS information is rendered into a version string. The default style, "pep440", produces a PEP440-compliant string, equal to the un-prefixed tag name for actual releases, and containing an additional "local version" section with more detail for in-between builds. For Git, this is TAG[+DISTANCE.gHEX[.dirty]] , using information from `git describe --tags --dirty --always`. For example "0.11+2.g1076c97.dirty" indicates that the tree is like the "1076c97" commit but has uncommitted changes (".dirty"), and that this commit is two revisions ("+2") beyond the "0.11" tag. For released software (exactly equal to a known tag), the identifier will only contain the stripped tag, e.g. "0.11". Other styles are available. See [details.md](details.md) in the Versioneer source tree for descriptions. ## Debugging Versioneer tries to avoid fatal errors: if something goes wrong, it will tend to return a version of "0+unknown". To investigate the problem, run `setup.py version`, which will run the version-lookup code in a verbose mode, and will display the full contents of `get_versions()` (including the `error` string, which may help identify what went wrong). ## Known Limitations Some situations are known to cause problems for Versioneer. This details the most significant ones. More can be found on Github [issues page](https://github.com/warner/python-versioneer/issues). ### Subprojects Versioneer has limited support for source trees in which `setup.py` is not in the root directory (e.g. `setup.py` and `.git/` are *not* siblings). The are two common reasons why `setup.py` might not be in the root: * Source trees which contain multiple subprojects, such as [Buildbot](https://github.com/buildbot/buildbot), which contains both "master" and "slave" subprojects, each with their own `setup.py`, `setup.cfg`, and `tox.ini`. Projects like these produce multiple PyPI distributions (and upload multiple independently-installable tarballs). * Source trees whose main purpose is to contain a C library, but which also provide bindings to Python (and perhaps other langauges) in subdirectories. Versioneer will look for `.git` in parent directories, and most operations should get the right version string. However `pip` and `setuptools` have bugs and implementation details which frequently cause `pip install .` from a subproject directory to fail to find a correct version string (so it usually defaults to `0+unknown`). `pip install --editable .` should work correctly. `setup.py install` might work too. Pip-8.1.1 is known to have this problem, but hopefully it will get fixed in some later version. [Bug #38](https://github.com/warner/python-versioneer/issues/38) is tracking this issue. The discussion in [PR #61](https://github.com/warner/python-versioneer/pull/61) describes the issue from the Versioneer side in more detail. [pip PR#3176](https://github.com/pypa/pip/pull/3176) and [pip PR#3615](https://github.com/pypa/pip/pull/3615) contain work to improve pip to let Versioneer work correctly. Versioneer-0.16 and earlier only looked for a `.git` directory next to the `setup.cfg`, so subprojects were completely unsupported with those releases. ### Editable installs with setuptools <= 18.5 `setup.py develop` and `pip install --editable .` allow you to install a project into a virtualenv once, then continue editing the source code (and test) without re-installing after every change. "Entry-point scripts" (`setup(entry_points={"console_scripts": ..})`) are a convenient way to specify executable scripts that should be installed along with the python package. These both work as expected when using modern setuptools. When using setuptools-18.5 or earlier, however, certain operations will cause `pkg_resources.DistributionNotFound` errors when running the entrypoint script, which must be resolved by re-installing the package. This happens when the install happens with one version, then the egg_info data is regenerated while a different version is checked out. Many setup.py commands cause egg_info to be rebuilt (including `sdist`, `wheel`, and installing into a different virtualenv), so this can be surprising. [Bug #83](https://github.com/warner/python-versioneer/issues/83) describes this one, but upgrading to a newer version of setuptools should probably resolve it. ### Unicode version strings While Versioneer works (and is continually tested) with both Python 2 and Python 3, it is not entirely consistent with bytes-vs-unicode distinctions. Newer releases probably generate unicode version strings on py2. It's not clear that this is wrong, but it may be surprising for applications when then write these strings to a network connection or include them in bytes-oriented APIs like cryptographic checksums. [Bug #71](https://github.com/warner/python-versioneer/issues/71) investigates this question. ## Updating Versioneer To upgrade your project to a new release of Versioneer, do the following: * install the new Versioneer (`pip install -U versioneer` or equivalent) * edit `setup.cfg`, if necessary, to include any new configuration settings indicated by the release notes. See [UPGRADING](./UPGRADING.md) for details. * re-run `versioneer install` in your source tree, to replace `SRC/_version.py` * commit any changed files ## Future Directions This tool is designed to make it easily extended to other version-control systems: all VCS-specific components are in separate directories like src/git/ . The top-level `versioneer.py` script is assembled from these components by running make-versioneer.py . In the future, make-versioneer.py will take a VCS name as an argument, and will construct a version of `versioneer.py` that is specific to the given VCS. It might also take the configuration arguments that are currently provided manually during installation by editing setup.py . Alternatively, it might go the other direction and include code from all supported VCS systems, reducing the number of intermediate scripts. ## License To make Versioneer easier to embed, all its code is dedicated to the public domain.
