.. contents:: :depth: 1 Introduction ============ .. figure:: http://www.netsight.co.uk/junk/xkcd-buildout.png :figwidth: image Let Mr. Developer help you win the everlasting buildout battle! (Remixed by Matt Hamilton, original from http://xkcd.com/303) ``mr.developer`` is a ``zc.buildout`` extension which makes it easier to work with buildouts containing lots of packages of which you only want to develop some. The basic idea for this comes from Wichert Akkerman's ``plonenext`` effort. Usage ===== You add ``mr.developer`` to the ``extensions`` option of your ``[buildout]`` section. Then you can add the following options to your ``[buildout]`` section: ``sources-dir`` This specifies the default directory where your development packages will be placed. Defaults to ``src``. ``sources`` This specifies the name of a section which lists the repository information of your packages. Defaults to ``sources``. ``auto-checkout`` This specifies the names of packages which should be checked out during buildout, packages already checked out are skipped. You can use ``*`` as a wild card for all packages in ``sources``. ``always-checkout`` This defaults to ``false``. If it's ``true``, then all packages specified by ``auto-checkout`` and currently in develop mode are updated during the buildout run. If set to ``force``, then packages are updated even when they are dirty instead of asking interactively. ``always-accept-server-certificate`` This defaults to ``false``. If it's ``true``, then invalid server certificates are accepted without asking for subversion repositories. The format of the section with the repository information is:: <name> = <kind> [key=value] <url> [path] [key=value] The different parts have the following meaning: ``<name>`` This is the package name. ``<kind>`` The kind of repository. Currently supported are one of ``svn`` (>= 1.5), ``hg``, ``git``, ``bzr``, ``cvs``, ``darcs`` or ``fs``. ``<url>`` The location of the repository. This value is specific to the version control system used. ``[path]`` .. important:: This is replaced by ``path=PATH`` syntax. The (optional) base directory where the package will be checked out. The name of the package will be appended. If it's not set, then ``sources-dir`` will be used. ``[key=value]`` You can add options for each individual package with this. There are is no whitespace allowed in ``key``, ``value`` and around the equal sign. For a description of the options see below. The different repository kinds accept some specific options. Common options The ``path`` option allows you to set the base directory where the package will be checked out. The name of the package will be appended to the base path. With ``full-path`` you can set the directory where the package will be checked out. This is the actual destination, nothing will be added. The ``update`` option allows you to specify whether a package will be updated during buildout or not. If it's ``true``, then it will always be updated. If it's ``false``, then it will never be updated, even if the global ``always-checkout`` option is set. The ``egg`` option makes it possible to manage packages which are not eggs with ``egg=false``. All commands like ``update`` work as expected, but the package isn't added to the ``develop`` buildout option and the ``activate`` and ``deactivate`` commands skip the package. ``svn`` The ``<url>`` is one of the urls supported by subversion. You can specify a url with a revision pin, like ``http://example.com/trunk@123``. You can also set the ``rev`` or ``revision`` option, which is either a pin like with ``rev=123`` or a minimum revision like ``rev=>123`` or ``rev=>=123``. When you set a minimum revision, the repository is updated when the current revision is lower. ``git`` The ``branch`` option allows you to use a specific branch instead of master. ``hg`` Currently no additional options. ``bzr`` Currently no additional options. ``cvs`` ``cvs_root`` option can be used to override the setting of the $CVSROOT environment variable. ``tag`` option force checkout/update of given tag instead of CVS HEAD. ``darcs`` Currently no additional options. ``fs`` This allows you to add packages on the filesystem without a version control system, or with an unsupported one. You can activate and deactivate packages, but you don't get status info and can't update etc. The ``<url>`` needs to be the same as the ``<name>`` of the package. The following is an example of how your ``buildout.cfg`` may look like:: [buildout] ... extensions = mr.developer sources = sources auto-checkout = my.package [sources] my.package = svn http://example.com/svn/my.package/trunk some.other.package = git git://example.com/git/some.other.package.git When you run buildout, you will get a script at ``bin/develop`` in your buildout directory. With that script you can perform various actions on the packages, like checking out the source code, without the need to know where the repository is located. For help on what the script can do, run ``bin/develop help``. If you checked out the source code of a package, you need run buildout again. The package will automatically be marked as an develop egg and, if it's listed in the section specified by the ``versions`` option in the ``[buildout]`` section, the version will be cleared, so the develop egg will actually be used. You can control the list of develop eggs explicitely with the ``activate`` and ``deactivate`` commands of ``bin/develop``. Troubleshooting =============== Dirty SVN --------- You get an error like:: ERROR: Can't switch package 'foo' from 'https://example.com/svn/foo/trunk/', because it's dirty. If you have not modified the package files under src/foo, then you can check what's going on with `status -v`. One common cause is a `*.egg-info` folder which gets generated every time you run buildout and this shows up as an untracked item in svn status. You should add .egg-info to your global Subversion ignores in `~/.subversion/config`, like this:: global-ignores = *.o *.lo *.la *.al .libs *.so *.so.[0-9]* *.a *.pyc *.pyo *.rej *~ #*# .#* .*.swp .DS_Store *.egg-info HTTPS certificates ------------------ The best way to handle https certificates at the moment, is to accept them permanently when checking out the source manually. Mercurial reports mismatching URL --------------------------------- This happens if you use lp:// URLs from launchpad. The problem is, that hg reports the actual URL, not the lp shortcut.
