<p>You can use Pygments from the shell, provided you installed the <cite>pygmentize</cite>
script:</p>
<pre class="literal-block">
$ pygmentize test.py
print &quot;Hello World&quot;
</pre>
<p>will print the file test.py to standard output, using the Python lexer
(inferred from the file name extension) and the terminal formatter (because
you didn't give an explicit formatter name).</p>
<p>If you want HTML output:</p>
<pre class="literal-block">
$ pygmentize -f html -l python -o test.html test.py
</pre>
<p>As you can see, the -l option explicitly selects a lexer. As seen above, if you
give an input file name and it has an extension that Pygments recognizes, you can
omit this option.</p>
<p>The <tt class="docutils literal"><span class="pre">-o</span></tt> option gives an output file name. If it is not given, output is
written to stdout.</p>
<p>The <tt class="docutils literal"><span class="pre">-f</span></tt> option selects a formatter (as with <tt class="docutils literal"><span class="pre">-l</span></tt>, it can also be omitted
if an output file name is given and has a supported extension).
If no output file name is given and <tt class="docutils literal"><span class="pre">-f</span></tt> is omitted, the
<cite>TerminalFormatter</cite> is used.</p>
<p>The above command could therefore also be given as:</p>
<pre class="literal-block">
$ pygmentize -o test.html test.py
</pre>
<p>To create a full HTML document, including line numbers and stylesheet (using the
&quot;emacs&quot; style), highlighting the Python file <tt class="docutils literal">test.py</tt> to <tt class="docutils literal">test.html</tt>:</p>
<pre class="literal-block">
$ pygmentize -O full,style=emacs -o test.html test.py
</pre>
<div class="section" id="options-and-filters">
<h3>Options and filters</h3>
<p>Lexer and formatter options can be given using the <tt class="docutils literal"><span class="pre">-O</span></tt> option:</p>
<pre class="literal-block">
$ pygmentize -f html -O style=colorful,linenos=1 -l python test.py
</pre>
<p>Be sure to enclose the option string in quotes if it contains any special shell
characters, such as spaces or expansion wildcards like <tt class="docutils literal">*</tt>. If an option
expects a list value, separate the list entries with spaces (you'll have to
quote the option value in this case too, so that the shell doesn't split it).</p>
<p>Since the <tt class="docutils literal"><span class="pre">-O</span></tt> option argument is split at commas and expects the split values
to be of the form <tt class="docutils literal">name=value</tt>, you can't give an option value that contains
commas or equals signs.  Therefore, an option <tt class="docutils literal"><span class="pre">-P</span></tt> is provided (as of Pygments
0.9) that works like <tt class="docutils literal"><span class="pre">-O</span></tt> but can only pass one option per <tt class="docutils literal"><span class="pre">-P</span></tt>. Its value
can then contain all characters:</p>
<pre class="literal-block">
$ pygmentize -P &quot;heading=Pygments, the Python highlighter&quot; ...
</pre>
<p>Filters are added to the token stream using the <tt class="docutils literal"><span class="pre">-F</span></tt> option:</p>
<pre class="literal-block">
$ pygmentize -f html -l pascal -F keywordcase:case=upper main.pas
</pre>
<p>As you see, options for the filter are given after a colon. As for <tt class="docutils literal"><span class="pre">-O</span></tt>, the
filter name and options must be one shell word, so there may not be any spaces
around the colon.</p>
</div>
<div class="section" id="generating-styles">
<h3>Generating styles</h3>
<p>Formatters normally don't output full style information.  For example, the HTML
formatter by default only outputs <tt class="docutils literal">&lt;span&gt;</tt> tags with <tt class="docutils literal">class</tt> attributes.
Therefore, there's a special <tt class="docutils literal"><span class="pre">-S</span></tt> option for generating style definitions.
Usage is as follows:</p>
<pre class="literal-block">
$ pygmentize -f html -S colorful -a .syntax
</pre>
<p>generates a CSS style sheet (because you selected the HTML formatter) for
the &quot;colorful&quot; style prepending a &quot;.syntax&quot; selector to all style rules.</p>
<p>For an explanation what <tt class="docutils literal"><span class="pre">-a</span></tt> means for <a class="reference external" href="./formatters.html">a particular formatter</a>, look for
the <cite>arg</cite> argument for the formatter's <cite>get_style_defs()</cite> method.</p>
</div>
<div class="section" id="getting-lexer-names">
<h3>Getting lexer names</h3>
<p><em>New in Pygments 1.0.</em></p>
<p>The <tt class="docutils literal"><span class="pre">-N</span></tt> option guesses a lexer name for a given filename, so that</p>
<pre class="literal-block">
$ pygmentize -N setup.py
</pre>
<p>will print out <tt class="docutils literal">python</tt>.  It won't highlight anything yet.  If no specific
lexer is known for that filename, <tt class="docutils literal">text</tt> is printed.</p>
</div>
<div class="section" id="getting-help">
<h3>Getting help</h3>
<p>The <tt class="docutils literal"><span class="pre">-L</span></tt> option lists lexers, formatters, along with their short
names and supported file name extensions, styles and filters. If you want to see
only one category, give it as an argument:</p>
<pre class="literal-block">
$ pygmentize -L filters
</pre>
<p>will list only all installed filters.</p>
<p>The <tt class="docutils literal"><span class="pre">-H</span></tt> option will give you detailed information (the same that can be found
in this documentation) about a lexer, formatter or filter. Usage is as follows:</p>
<pre class="literal-block">
$ pygmentize -H formatter html
</pre>
<p>will print the help for the HTML formatter, while</p>
<pre class="literal-block">
$ pygmentize -H lexer python
</pre>
<p>will print the help for the Python lexer, etc.</p>
</div>
<div class="section" id="a-note-on-encodings">
<h3>A note on encodings</h3>
<p><em>New in Pygments 0.9.</em></p>
<p>Pygments tries to be smart regarding encodings in the formatting process:</p>
<ul class="simple">
<li>If you give an <tt class="docutils literal">encoding</tt> option, it will be used as the input and
output encoding.</li>
<li>If you give an <tt class="docutils literal">outencoding</tt> option, it will override <tt class="docutils literal">encoding</tt>
as the output encoding.</li>
<li>If you don't give an encoding and have given an output file, the default
encoding for lexer and formatter is <tt class="docutils literal">latin1</tt> (which will pass through
all non-ASCII characters).</li>
<li>If you don't give an encoding and haven't given an output file (that means
output is written to the console), the default encoding for lexer and
formatter is the terminal encoding (<cite>sys.stdout.encoding</cite>).</li>
</ul>
