class HtmlFormatter(Formatter):

r"""
|
|
|
|
|
Format tokens as HTML 4 ``<span>`` tags within a ``<pre>`` tag, wrapped
|
|
|
|
|
in a ``<div>`` tag. The ``<div>``'s CSS class can be set by the `cssclass`
|
|
|
|
|
option.
|
|
|
|
|
|
|
|
|
|
If the `linenos` option is set to ``"table"``, the ``<pre>`` is
|
|
|
|
|
additionally wrapped inside a ``<table>`` which has one row and two
|
|
|
|
|
cells: one containing the line numbers and one containing the code.
|
|
|
|
|
Example:
|
|
|
|
|
|
|
|
|
|
.. sourcecode:: html
|
|
|
|
|
|
|
|
|
|
<div class="highlight" >
|
|
|
|
|
<table><tr>
|
|
|
|
|
<td class="linenos" title="click to toggle"
|
|
|
|
|
onclick="with (this.firstChild.style)
|
|
|
|
|
{ display = (display == '') ? 'none' : '' }">
|
|
|
|
|
<pre>1
|
|
|
|
|
2</pre>
|
|
|
|
|
</td>
|
|
|
|
|
<td class="code">
|
|
|
|
|
<pre><span class="Ke">def </span><span class="NaFu">foo</span>(bar):
|
|
|
|
|
<span class="Ke">pass</span>
|
|
|
|
|
</pre>
|
|
|
|
|
</td>
|
|
|
|
|
</tr></table></div>
|
|
|
|
|
|
|
|
|
|
(whitespace added to improve clarity).
|
|
|
|
|
|
|
|
|
|
Wrapping can be disabled using the `nowrap` option.
|
|
|
|
|
|
|
|
|
|
A list of lines can be specified using the `hl_lines` option to make these
|
|
|
|
|
lines highlighted (as of Pygments 0.11).
|
|
|
|
|
|
|
|
|
|
With the `full` option, a complete HTML 4 document is output, including
|
|
|
|
|
the style definitions inside a ``<style>`` tag, or in a separate file if
|
|
|
|
|
the `cssfile` option is given.
|
|
|
|
|
|
|
|
|
|
When `tagsfile` is set to the path of a ctags index file, it is used to
|
|
|
|
|
generate hyperlinks from names to their definition. You must enable
|
2016-06-13 14:41:17 +00:00
|
|
|
`lineanchors` and run ctags with the `-n` option for this to work. The
|
2013-09-22 20:39:16 +00:00
|
|
|
`python-ctags` module from PyPI must be installed to use this feature;
|
|
|
|
|
otherwise a `RuntimeError` will be raised.
|
|
|
|
|
|
|
|
|
|
The `get_style_defs(arg='')` method of a `HtmlFormatter` returns a string
|
|
|
|
|
containing CSS rules for the CSS classes used by the formatter. The
|
|
|
|
|
argument `arg` can be used to specify additional CSS selectors that
|
|
|
|
|
are prepended to the classes. A call `fmter.get_style_defs('td .code')`
|
|
|
|
|
would result in the following CSS classes:
|
|
|
|
|
|
|
|
|
|
.. sourcecode:: css
|
|
|
|
|
|
|
|
|
|
td .code .kw { font-weight: bold; color: #00FF00 }
|
|
|
|
|
td .code .cm { color: #999999 }
|
|
|
|
|
...
|
|
|
|
|
|
|
|
|
|
If you have Pygments 0.6 or higher, you can also pass a list or tuple to the
|
|
|
|
|
`get_style_defs()` method to request multiple prefixes for the tokens:
|
|
|
|
|
|
|
|
|
|
.. sourcecode:: python
|
|
|
|
|
|
|
|
|
|
formatter.get_style_defs(['div.syntax pre', 'pre.syntax'])
|
|
|
|
|
|
|
|
|
|
The output would then look like this:
|
|
|
|
|
|
|
|
|
|
.. sourcecode:: css
|
|
|
|
|
|
|
|
|
|
div.syntax pre .kw,
|
|
|
|
|
pre.syntax .kw { font-weight: bold; color: #00FF00 }
|
|
|
|
|
div.syntax pre .cm,
|
|
|
|
|
pre.syntax .cm { color: #999999 }
|
|
|
|
|
...
|
|
|
|
|
|
|
|
|
|
Additional options accepted:
|
|
|
|
|
|
|
|
|
|
`nowrap`
|
|
|
|
|
If set to ``True``, don't wrap the tokens at all, not even inside a ``<pre>``
|
|
|
|
|
tag. This disables most other options (default: ``False``).
|
|
|
|
|
|
|
|
|
|
`full`
|
|
|
|
|
Tells the formatter to output a "full" document, i.e. a complete
|
|
|
|
|
self-contained document (default: ``False``).
|
|
|
|
|
|
|
|
|
|
`title`
|
|
|
|
|
If `full` is true, the title that should be used to caption the
|
|
|
|
|
document (default: ``''``).
|
|
|
|
|
|
|
|
|
|
`style`
|
|
|
|
|
The style to use, can be a string or a Style subclass (default:
|
|
|
|
|
``'default'``). This option has no effect if the `cssfile`
|
|
|
|
|
and `noclobber_cssfile` option are given and the file specified in
|
|
|
|
|
`cssfile` exists.
|
|
|
|
|
|
|
|
|
|
`noclasses`
|
|
|
|
|
If set to true, token ``<span>`` tags will not use CSS classes, but
|
|
|
|
|
inline styles. This is not recommended for larger pieces of code since
|
|
|
|
|
it increases output size by quite a bit (default: ``False``).
|
|
|
|
|
|
|
|
|
|
`classprefix`
|
|
|
|
|
Since the token types use relatively short class names, they may clash
|
|
|
|
|
with some of your own class names. In this case you can use the
|
|
|
|
|
`classprefix` option to give a string to prepend to all Pygments-generated
|
|
|
|
|
CSS class names for token types.
|
|
|
|
|
Note that this option also affects the output of `get_style_defs()`.
|
|
|
|
|
|
|
|
|
|
`cssclass`
|
|
|
|
|
CSS class for the wrapping ``<div>`` tag (default: ``'highlight'``).
|
|
|
|
|
If you set this option, the default selector for `get_style_defs()`
|
|
|
|
|
will be this class.
|
|
|
|
|
|
2014-12-01 06:10:30 +00:00
|
|
|
.. versionadded:: 0.9
|
|
|
|
|
If you select the ``'table'`` line numbers, the wrapping table will
|
|
|
|
|
have a CSS class of this string plus ``'table'``, the default is
|
|
|
|
|
accordingly ``'highlighttable'``.
|
2013-09-22 20:39:16 +00:00
|
|
|
|
|
|
|
|
`cssstyles`
|
|
|
|
|
Inline CSS styles for the wrapping ``<div>`` tag (default: ``''``).
|
|
|
|
|
|
|
|
|
|
`prestyles`
|
2014-12-01 06:10:30 +00:00
|
|
|
Inline CSS styles for the ``<pre>`` tag (default: ``''``).
|
|
|
|
|
|
|
|
|
|
.. versionadded:: 0.11
|
2013-09-22 20:39:16 +00:00
|
|
|
|
|
|
|
|
`cssfile`
|
|
|
|
|
If the `full` option is true and this option is given, it must be the
|
|
|
|
|
name of an external file. If the filename does not include an absolute
|
|
|
|
|
path, the file's path will be assumed to be relative to the main output
|
|
|
|
|
file's path, if the latter can be found. The stylesheet is then written
|
2014-12-01 06:10:30 +00:00
|
|
|
to this file instead of the HTML file.
|
|
|
|
|
|
|
|
|
|
.. versionadded:: 0.6
|
2013-09-22 20:39:16 +00:00
|
|
|
|
|
|
|
|
`noclobber_cssfile`
|
|
|
|
|
If `cssfile` is given and the specified file exists, the css file will
|
|
|
|
|
not be overwritten. This allows the use of the `full` option in
|
|
|
|
|
combination with a user specified css file. Default is ``False``.
|
2014-12-01 06:10:30 +00:00
|
|
|
|
|
|
|
|
.. versionadded:: 1.1
|
2013-09-22 20:39:16 +00:00
|
|
|
|
|
|
|
|
`linenos`
|
|
|
|
|
If set to ``'table'``, output line numbers as a table with two cells,
|
|
|
|
|
one containing the line numbers, the other the whole code. This is
|
|
|
|
|
copy-and-paste-friendly, but may cause alignment problems with some
|
|
|
|
|
browsers or fonts. If set to ``'inline'``, the line numbers will be
|
|
|
|
|
integrated in the ``<pre>`` tag that contains the code (that setting
|
|
|
|
|
is *new in Pygments 0.8*).
|
|
|
|
|
|
|
|
|
|
For compatibility with Pygments 0.7 and earlier, every true value
|
|
|
|
|
except ``'inline'`` means the same as ``'table'`` (in particular, that
|
|
|
|
|
means also ``True``).
|
|
|
|
|
|
|
|
|
|
The default value is ``False``, which means no line numbers at all.
|
|
|
|
|
|
|
|
|
|
**Note:** with the default ("table") line number mechanism, the line
|
|
|
|
|
numbers and code can have different line heights in Internet Explorer
|
|
|
|
|
unless you give the enclosing ``<pre>`` tags an explicit ``line-height``
|
|
|
|
|
CSS property (you get the default line spacing with ``line-height:
|
|
|
|
|
125%``).
|
|
|
|
|
|
|
|
|
|
`hl_lines`
|
2014-12-01 06:10:30 +00:00
|
|
|
Specify a list of lines to be highlighted.
|
|
|
|
|
|
|
|
|
|
.. versionadded:: 0.11
|
2013-09-22 20:39:16 +00:00
|
|
|
|
|
|
|
|
`linenostart`
|
|
|
|
|
The line number for the first line (default: ``1``).
|
|
|
|
|
|
|
|
|
|
`linenostep`
|
|
|
|
|
If set to a number n > 1, only every nth line number is printed.
|
|
|
|
|
|
|
|
|
|
`linenospecial`
|
|
|
|
|
If set to a number n > 0, every nth line number is given the CSS
|
|
|
|
|
class ``"special"`` (default: ``0``).
|
|
|
|
|
|
|
|
|
|
`nobackground`
|
|
|
|
|
If set to ``True``, the formatter won't output the background color
|
|
|
|
|
for the wrapping element (this automatically defaults to ``False``
|
|
|
|
|
when there is no wrapping element [eg: no argument for the
|
2014-12-01 06:10:30 +00:00
|
|
|
`get_syntax_defs` method given]) (default: ``False``).

.. versionadded:: 0.6
|
2013-09-22 20:39:16 +00:00
|
|
|
|
|
|
|
|
`lineseparator`
|
|
|
|
|
This string is output between lines of code. It defaults to ``"\n"``,
|
|
|
|
|
which is enough to break a line inside ``<pre>`` tags, but you can
|
2014-12-01 06:10:30 +00:00
|
|
|
e.g. set it to ``"<br>"`` to get HTML line breaks.
|
|
|

|

|
.. versionadded:: 0.7
|
2013-09-22 20:39:16 +00:00
|
|
|
|
|
|
|
|
`lineanchors`
|
|
|
|
|
If set to a nonempty string, e.g. ``foo``, the formatter will wrap each
|
|
|
|
|
output line in an anchor tag with a ``name`` of ``foo-linenumber``.
|
2014-12-01 06:10:30 +00:00
|
|
|
This allows easy linking to certain lines.
|
|
|
|

2013-09-22 20:39:16 +00:00
|
|

|
|
|
|
`linespans`
|
|
|
|
|
If set to a nonempty string, e.g. ``foo``, the formatter will wrap each
|
|
|
|
|
output line in a span tag with an ``id`` of ``foo-linenumber``.
|
2014-12-01 06:10:30 +00:00
|
|
|
This allows easy access to lines via javascript.

`anchorlinenos`
|
|
|
|
|
If set to `True`, will wrap line numbers in <a> tags. Used in
|
|
|
|
|
combination with `linenos` and `lineanchors`.
|
|
|
|
|
|
|
|
|
|
`tagsfile`
|
|
|
|
|
If set to the path of a ctags file, wrap names in anchor tags that
|
|
|
|
|
link to their definitions. `lineanchors` should be used, and the
|
|
|
|
|
tags file should specify line numbers (see the `-n` option to ctags).

Available variables are `%(path)s`, `%(fname)s` and `%(fext)s`.
|
|
|
|
|
Defaults to an empty string, resulting in just `#prefix-number` links.

**Subclassing the HTML formatter**
|
|

|
|
|
|
|
|
|
|
The HTML formatter is now built in a way that allows easy subclassing, thus
|
|
|
|
|
customizing the output HTML code. The `format()` method calls
|
|
|
|
|
`self._format_lines()` which returns a generator that yields tuples of ``(1,
|
|
|
|
|
line)``, where the ``1`` indicates that the ``line`` is a line of the
|
|
|
|
|
formatted source code.
|
|
|
|
|
|
|
|
|
|
If the `nowrap` option is set, the generator is the iterated over and the
|
|
|
|
|
resulting HTML is output.
|
|
|
|
|
|
|
|
|
|
Otherwise, `format()` calls `self.wrap()`, which wraps the generator with
|
|
|
|
|
other generators. These may add some HTML code to the one generated by
|
|
|
|
|
`_format_lines()`, either by modifying the lines generated by the latter,
|
|
|
|
|
then yielding them again with ``(1, line)``, and/or by yielding other HTML
|
|
|
|
|
code before or after the lines, with ``(0, html)``. The distinction between
|
|
|
|
|
source lines and other code makes it possible to wrap the generator multiple
|
|
|
|
|
times.
|
|
|
|
|
|
|
|
|
|
The default `wrap()` implementation adds a ``<div>`` and a ``<pre>`` tag.
|
|
|
|
|
|
|
|
|
|
A custom `HtmlFormatter` subclass could look like this:
|
|
|
|
|
|
|
|
|
|
.. sourcecode:: python
|
|
|
|
|
|
|
|
|
|
class CodeHtmlFormatter(HtmlFormatter):
|
|
|
|
|
|
|
|
|
|
def wrap(self, source, outfile):
|
|
|
|
|
return self._wrap_code(source)
|
|
|
|
|
|
|
|
|
|
def _wrap_code(self, source):
|
|
|
|
|
yield 0, '<code>'
|
|
|
|
|
for i, t in source:
|
|
|
|
|
if i == 1:
|
|
|
|
|
# it's a line of formatted code
|
|
|
|
|
t += '<br>'
|
|
|
|
|
yield i, t
|
|
|
|
|
yield 0, '</code>'
|
|
|
|
|
|
|
|
|
|
This results in wrapping the formatted lines with a ``<code>`` tag, where the
|
|
|
|
|
source lines are broken using ``<br>`` tags.
|
|
|
|
|
|
|
|
|
|
After calling `wrap()`, the `format()` method also adds the "line numbers"
|
|
|
|
|
and/or "full document" wrappers if the respective options are set. Then, all
|
|
|
|
|
HTML yielded by the wrapped generator is output.
