<p>Most <strong>rest2web</strong> configuration is done through the config file. It is
generally easier to edit a single text file than to have to remember lots of
arcane command line options.  <img src="images/smilies/smile.gif" alt="Smile" /> </p>
<p>There are several things you can control from the command line. These include :</p>
<ul class="simple">
<li>The <a class="reference external" href="config_file.html">Config File</a></li>
<li>The verbosity level (how much information rest2web outputs as it runs</li>
<li>Override the template file</li>
<li>Go into force mode</li>
<li>Specify global <a class="reference external" href="reference/uservalues.html">uservalues</a></li>
</ul>
</div>
<div class="section" id="basic-usage">
<h1><a class="toc-backref" href="#id3">Basic Usage</a></h1>
<p>If you type <tt class="docutils literal"><span class="pre">r2w.py</span> <span class="pre">--help</span></tt> at the command line, this is the message it
<em>should</em> print :</p>
<pre class="literal-block">
usage: r2w.py [options] config_file

options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -v                    Verbose output (default).
  -a                    Display warnings &amp; actions only.
  -w                    Display warnings only.
  -t TEMPLATE, --template-file=TEMPLATE
                        Specify a template file. (Overrides first template.)
  -u USERVALUES, --uservalues=USERVALUES
                        Global uservalues for the site, in the form
                        &quot;name=value&quot;.
  -f, --force           Force site without indexes, restindexes or template.
  -n, --nopause         Do not pause after processing (overrides setting in config file).
  -s, --skiperrors      Skip errors (continue processing).

<div class="note">
<p class="first admonition-title">Note</p>
<p>Command line options are processed using <a class="reference external" href="http://docs.python.org/lib/module-optparse.html">optparse</a>.</p>
<p class="last">This only comes with Python 2.3 and more recent. On Python 2.2 you will
only be able to pass the config file at the command line.</p>
</div>
</div>
<div class="section" id="the-config-file">
<h1><a class="toc-backref" href="#id4">The Config File</a></h1>
<p>If you run <tt class="docutils literal"><span class="pre">r2w.py</span></tt> <em>without</em> any command line options, it looks for a file
called <tt class="docutils literal"><span class="pre">r2w.ini</span></tt> in the current working directory.</p>
<p>Alternatively you can specify a <a class="reference external" href="config_file.html">config file</a> as the last argument to <tt class="docutils literal"><span class="pre">r2w.py</span></tt>.</p>
</div>
<div class="section" id="verbosity-level">
<h1><a class="toc-backref" href="#id5">Verbosity Level</a></h1>
<p>By default rest2web outputs a lot of information about what it does. This
includes which directories and files it is processing, as well any errors
raised along the way.</p>
<p>This may be too much information. There are three different verbosity levels :</p>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">-v</span></tt> - Verbose, the default level. Information, actions and errors.</li>
<li><tt class="docutils literal"><span class="pre">-a</span></tt> - Action level. Actions and errors only.</li>
<li><tt class="docutils literal"><span class="pre">-w</span></tt> - Warning level. Warnings only.</li>
</ul>
</div>
<div class="section" id="template-file">
<h1><a class="toc-backref" href="#id6">Template File</a></h1>
<p>rest2web uses template files to generate the output pages. See <a class="reference external" href="templating.html">Templating</a>
for the details of this.</p>
<p>Often you will only use a single template, specified in the <a class="reference external" href="restindex.shtml">restindex</a>
of your top level index page. Sometimes you may want to use alternative templates
for the same site. For example one for the online version and one for the
distributed documentation.</p>
<p>You can override the top level template from the command line, using either :</p>
<blockquote>
<p><tt class="docutils literal"><span class="pre">r2w.py</span> <span class="pre">-t</span> <span class="pre">path/to/template.txt</span></tt></p>
<p><tt class="docutils literal"><span class="pre">r2w.py</span> <span class="pre">--template-file=path/to/template.txt</span></tt></p>
</blockquote>
</div>
<div class="section" id="id1">
<h1><a class="toc-backref" href="#id7">Uservalues</a></h1>
<p><a class="reference external" href="reference/uservalues.html">The Uservalues</a> are a way of providing values to
use in your content and templates. They can be useful for multiple translations,
or for values that you want to specify at the time you build your site.</p>
<p>You can specify uservalues in the restindex of each page. You can also specify
<em>global</em> uservalues (available in every page) in the config file, or at the
command line.</p>
<p>If you specify the same values in your config file <em>and</em> at the command line,
the command line takes higher priority.</p>
<p>A uservalue needs a name (this is how you refer to it in pages/templates) and
a value. The name and value should be separated by an equals sign.</p>
<p>This means that you can specify uservalues at the command line using either :</p>
<blockquote>
<p><tt class="docutils literal"><span class="pre">r2w.py</span> <span class="pre">-u</span> <span class="pre">&quot;name=value&quot;</span></tt></p>
<p><tt class="docutils literal"><span class="pre">r2w.py</span> <span class="pre">--uservalues=&quot;name=value&quot;</span></tt></p>
</blockquote>
<p>The double quotes are optional, but useful if the value has spaces.</p>
<p>Uservalues in pages will override global uservalues specified in either the
config file or at the command line.</p>
</div>
<div class="section" id="force-mode">
<h1><a class="toc-backref" href="#id8">Force Mode</a></h1>
<p><a class="reference external" href="force_mode.html">force mode</a> allows you to build websites without specifying
a template, providing indexes, or having restindexes in the ReST documents that
form your pages.</p>
<p>You can supply any of these that you want, but where they are missing rest2web
will supply defaults.</p>
<p>To switch force mode onfrom the command line, use :</p>
<blockquote>
<p><tt class="docutils literal"><span class="pre">r2w.py</span> <span class="pre">-f</span></tt></p>
<p><tt class="docutils literal"><span class="pre">r2w.py</span> <span class="pre">--force</span></tt></p>
</blockquote>
</div>
<div class="section" id="no-pause">
<h1><a class="toc-backref" href="#id9">No Pause</a></h1>
<p>This overrides the 'pause' option in the config file, and forces 'r2w.py' to
<em>not pause</em> after running.</p>
</div>
<div class="section" id="skiperrors">
<h1><a class="toc-backref" href="#id10">skiperrors</a></h1>
<p>This option determines how rest2web will handle exceptions (like our old friend <tt class="docutils literal"><span class="pre">UnicodeDecodeError</span></tt>) that happen when processing pages.</p>
<p>If set, rest2web will display the error and move to the next file. The default is off.</p>
<div class="note">
<p class="first admonition-title">Note</p>
<p>If an error occurs whilst trying to process an index file, it will have to skip building the directory.</p>
<p class="last">This feature is still 'experimental' and may need refining.</p>
