Configuring Bazaar ================== Telling Bazaar about yourself ----------------------------- One function of a version control system is to keep track of who changed what. In a decentralized system, that requires an identifier for each author that is globally unique. Most people already have one of these: an email address. Bazaar is smart enough to automatically generate an email address by looking up your username and hostname. If you don't like the guess that Bazaar makes, then use the ``whoami`` command to set the identifier you want:: % bzr whoami "Your Name " If ``whoami`` is used without an argument, the current value is displayed. Using a network proxy --------------------- If your network requires that you use an HTTP proxy for outbound connections, you must set the ``http_proxy`` variable. If the proxy is also required for https connections, you need to set ``https_proxy`` too. If you need these and don't have them set, you may find that connections to Launchpad or other external servers fail or time out. On Unix you typically want to set these in ``/etc/environment`` or ``~/.bash_profile`` and on Windows in the user profile. :: http_proxy=http://proxy.example.com:3128/ https_proxy=http://proxy.example.com:3128/ The ``no_proxy`` variable can be set to a comma-separated list of hosts which shouldn't be reached by the proxy. (See for more details.) Various ways to configure ------------------------- As shown in the example above, there are various ways to configure Bazaar, they all share some common properties though. An option has: - a name which is generally a valid python identifier, - a value which is a string. In some cases, Bazaar will be able to recognize special values like 'True', 'False' to infer a boolean type, but basically, as a user, you will always specify a value as a string. Options are grouped in various contexts so the option name uniquely identifies it in this context. When needed, options can be made persistent by recording them in a configuration file. Configuration files ------------------- Configuration files are located in ``$HOME/.bazaar`` on Unix and ``C:\Documents and Settings\\Application Data\Bazaar\2.0`` on Windows. There are three primary configuration files in this location: * ``bazaar.conf`` describes default configuration options, * ``locations.conf`` describes configuration information for specific branch locations, * ``authentication.conf`` describes credential information for remote servers. Each branch can also contain a configuration file that sets values specific to that branch. This file is found at ``.bzr/branch/branch.conf`` within the branch. This file is visible to **all users of a branch**. If you wish to override one of the values for a branch with a setting that is specific to you, then you can do so in ``locations.conf``. Here is sample content of ``bazaar.conf`` after setting an email address using the ``whoami`` command:: [DEFAULT] email = Your Name For further details on the syntax and configuration settings supported, see `Configuration Settings <../user-reference/index.html#configuration-settings>`_ in the Bazaar User Reference. Looking at the active configuration ----------------------------------- To look at all the currently defined options, you can use the following command:: bzr config ``bzr`` implements some rules to decide where to get the value of a configuration option. The current policy is to examine the existing configurations files in a given order for matching definitions. * ``locations.conf`` is searched first for a section whose name matches the location considered (working tree, branch or remote branch), * the current ``branch.conf`` is searched next, * ``bazaar.conf`` is searched next, * finally, some options can have default values generally defined in the code itself and not displayed by ``bzr config`` (see `Configuration Settings <../user-reference/index.html#configuration-settings>`_). This is better understood by using ```bzr config`` with no arguments, which will display some output of the form:: locations: post_commit_to = commits@example.com news_merge_files = NEWS branch: parent_location = bzr+ssh://bazaar.launchpad.net/+branch/bzr/ nickname = config-modify push_location = bzr+ssh://bazaar.launchpad.net/~vila/bzr/config-modify/ bazaar: debug_flags = hpss, Each configuration file is associated with a given scope whose name is displayed before each set of defined options. If you need to look at a specific option, you can use:: bzr config
