In normal cases it should be installed automatically with the actual extension, read below for more tricky cases (in particular, for information about installation on Windows). .. note:: This document uses `Dynamic Username`_ in examples, but the same method should work for any other extension which requires ``mercurial_extension_utils``. Installing on Linux/Unix ------------------------------------------------------- In typical case ``mercurial_extension_utils`` should be installed automatically, without requiring your attention, by commands like ``pip install mercurial_dynamic_username``. If for some reason it did not work, just install from PyPi with:: pip install --user mercurial_extension_utils or system-wide with:: sudo pip install mercurial_extension_utils If you don't have ``pip``, try:: sudo easy_install mercurial_extension_utils Upgrade to newer version using the same commands with ``--upgrade`` option added, for example:: pip install --user --upgrade mercurial_extension_utils If you miss both ``pip``, and ``easy_install``, follow recipe from `Installing for development`_ section. Installing on Windows ------------------------------------------------------- Windows Mercurial distributions (including most popular - and well deserving that - TortoiseHg_) are not using system Python (in fact, one may use Mercurial without installing Python at all), and installing into bundled Python path is uneasy. To remedy that, extensions utilizing this module handle additional methods of locating it. The following two methods of installation are available: 1. If you have some Python installed, you may still install both this module, and extension using it, from PyPi. For example:: pip install mercurial_extension_utils pip install mercurial_dynamic_username This will not (yet) make the module visible to your Mercurial, but you will get all the necessary files installed on your computer. Then activate the actual extension in charge by specifying it's path, for example by writing in your ``Mercurial.ini``:: [extensions] mercurial_dynamic_username = C:/Python27/Lib/site-packages/mercurial_dynamic_username.py .. note:: This works because ``mercurial_dynamic_username.py`` checks for ``mercurial_extension_utils.py`` saved in the same directory (and ``pip`` installs both modules in the same place). You can get the same effect by manually downloading all files into the same directory (using ``pip`` is more handy as it tracks dependencies and supports upgrades). Upgrade with ``pip`` by adding ``--upgrade`` to it's options. 2. If you don't have any Python, clone both the extension(s) repository and ``mercurial_extension_utils``` and put them in the same place, for example:: cd c:\MercurialPlugins hg clone https://bitbucket.org/Mekk/mercurial-extension_utils/ hg clone https://bitbucket.org/Mekk/mercurial-dynamic_username/ Update repositories to newest tagged versions (untagged versions may be unstable or not working). Activate the actual extension by specifying it's path, for example by writing in ``Mercurial.ini``:: [extensions] mercurial_dynamic_username = C:/MercurialPlugins/mercurial-dynamic_username/mercurial_dynamic_username.py .. note:: Directory names matter. This works because ``mercurial_dynamic_username.py`` checks for ``mercurial_extension_utils.py`` in ``../mercurial_extension_utils`` and ``../extension_utils`` (relative to it's own location). To upgrade to new version, simply pull and update to newer tag. Installing for development ------------------------------------------------------- On Windows use second variant from the previous chapter (clone and activate by path). On Linux/Unix do the same. Clone all the necessary repositories, for example:: cd ~/sources/ hg clone https://bitbucket.org/Mekk/mercurial-extension_utils/ hg clone https://bitbucket.org/Mekk/mercurial-dynamic_username/ then either make it visible to Python by repeating in every repo:: pip install --user -e . or activate the extension(s) by full path, by writing in ``~/.hgrc`` something like:: [extensions] mercurial_dynamic_username = ~/sources/mercurial-dynamic_username/mercurial_dynamic_username.py For Mercurial extensions developers ==================================== Contained functions are mostly tiny utilities related to configuration processing or location matching. They either extend Mercurial APIs a bit (like function to iterate config items which match regexp), or support tasks which aren't strictly Mercurial related, but happen repeatably during extension writing (like matching repository root against set of paths defined in configuration).
