<div class="section" id="what-does-bazaar-track">
<h2>What does Bazaar track?<a class="headerlink" href="#what-does-bazaar-track" title="Permalink to this headline">¶</a></h2>
<p>As explained earlier, <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">add</span></tt> finds and registers all the things in
and under the current directory that Bazaar thinks ought to be
version controlled. These things may be:</p>
<blockquote>
<div><ul class="simple">
<li>files</li>
<li>directories</li>
<li>symbolic links.</li>
</ul>
</div></blockquote>
<p>Bazaar has default rules for deciding which files are
interesting and which ones are not. You can tune those rules as
explained in <a class="reference internal" href="#ignoring-files">Ignoring files</a> below.</p>
<p>Unlike many other VCS tools, Bazaar tracks directories as first class
items. As a consequence, empty directories are correctly supported -
you don’t need to create a dummy file inside a directory just to
ensure it gets tracked and included in project exports.</p>
<p>For symbolic links, the value of the symbolic link is tracked,
not the content of the thing the symbolic link is pointing to.</p>
<p>Note: Support for tracking projects-within-projects (“nested trees”)
is currently under development. Please contact the Bazaar developers
if you are interested in helping develop or test this functionality.</p>
</div>
<div class="section" id="selective-registration">
<h2>Selective registration<a class="headerlink" href="#selective-registration" title="Permalink to this headline">¶</a></h2>
<p>In some cases, you may want or need to explicitly nominate the things
to register rather than leave it up to Bazaar to find things. To do this,
simply provide paths as arguments to the <tt class="docutils literal"><span class="pre">add</span></tt> command like this:</p>
<div class="highlight-python"><pre>bzr add fileX dirY/</pre>
</div>
<p>Adding a directory implicitly adds all interesting things
underneath it.</p>
</div>
<div class="section" id="ignoring-files">
<h2>Ignoring files<a class="headerlink" href="#ignoring-files" title="Permalink to this headline">¶</a></h2>
<p>Many source trees contain some files that do not need to be versioned,
such as editor backups, object or bytecode files, and built programs. You
can simply not add them, but then they’ll always crop up as unknown files.
You can also tell Bazaar to ignore these files by adding them to a file
called <tt class="docutils literal"><span class="pre">.bzrignore</span></tt> at the top of the tree.</p>
<p>This file contains a list of file wildcards (or “globs”), one per line.
Typical contents are like this:</p>
<div class="highlight-python"><pre>*.o
*~
*.tmp
*.py[co]</pre>
</div>
<p>If a glob contains a slash, it is matched against the whole path from the
top of the tree; otherwise it is matched against only the filename. So
the previous example ignores files with extension <tt class="docutils literal"><span class="pre">.o</span></tt> in all
subdirectories, but this example ignores only <tt class="docutils literal"><span class="pre">config.h</span></tt> at the top level
and HTML files in <tt class="docutils literal"><span class="pre">doc/</span></tt>:</p>
<div class="highlight-python"><pre>./config.h
doc/*.html</pre>
</div>
<p>To get a list of which files are ignored and what pattern they matched,
use <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">ignored</span></tt>:</p>
<div class="highlight-python"><pre>% bzr ignored
config.h ./config.h
configure.in~ *~</pre>
</div>
<p>Note that ignore patterns are only matched against non-versioned files,
and control whether they are treated as “unknown” or “ignored”. If a file
is explicitly added, it remains versioned regardless of whether it matches
an ignore pattern.</p>
<p>The <tt class="docutils literal"><span class="pre">.bzrignore</span></tt> file should normally be versioned, so that new copies
of the branch see the same patterns:</p>
<div class="highlight-python"><pre>% bzr add .bzrignore
% bzr commit -m "Add ignore patterns"</pre>
</div>
<p>The command <tt class="docutils literal"><span class="pre">bzr</span> <span class="pre">ignore</span> <span class="pre">PATTERN</span></tt> can be used to easily add PATTERN to
the <tt class="docutils literal"><span class="pre">.bzrignore</span> <span class="pre">file</span></tt> (creating it if necessary and registering it to
be tracked by Bazaar). Removing and modifying patterns are done by
directly editing the <tt class="docutils literal"><span class="pre">.bzrignore</span></tt> file.</p>
</div>
<div class="section" id="global-ignores">
<h2>Global ignores<a class="headerlink" href="#global-ignores" title="Permalink to this headline">¶</a></h2>
<p>There are some ignored files which are not project specific, but more user
specific. Things like editor temporary files, or personal temporary files.
Rather than add these ignores to every project, bzr supports a global
ignore file in <tt class="docutils literal"><span class="pre">~/.bazaar/ignore</span></tt> <a class="footnote-reference" href="#id2" id="id1">[1]</a>. It has the same syntax as the
per-project ignore file.</p>
<table class="docutils footnote" frame="void" id="id2" rules="none">
<colgroup><col class="label" /><col /></colgroup>
<tbody valign="top">
<tr><td class="label"><a class="fn-backref" href="#id1">[1]</a></td><td>On Windows, the users configuration files can be found in the
application data directory. So instead of <tt class="docutils literal"><span class="pre">~/.bazaar/branch.conf</span></tt>
the configuration file can be found as:
<tt class="docutils literal"><span class="pre">C:\Documents</span> <span class="pre">and</span> <span class="pre">Settings\<username>\Application</span> <span class="pre">Data\Bazaar\2.0\branch.conf</span></tt>.
The same is true for <tt class="docutils literal"><span class="pre">locations.conf</span></tt>, <tt class="docutils literal"><span class="pre">ignore</span></tt>, and the
<tt class="docutils literal"><span class="pre">plugins</span></tt> directory.</td></tr>
