This is an extension to Python-Markdown which provides an "include" function, similar to that found in LaTeX (and also the C pre-processor and Fortran). I originally wrote it for my FORD Fortran auto-documentation generator.
InstallationThis module can now be installed using pip
.
pip install markdown-include
Tests
Use the unittest module
python -m unittest discover unittests/Usage
This module can be used in a program in the following way:
import markdown html = markdown.markdown(source, extensions=['markdown_include.include'])
Markdown-Include can also be included in MkDocs projects like below:
markdown_extensions: - markdown_include.include: base_path: docs
The syntax for use within your Markdown files is {!filename!}
. This statement will be replaced by the contents of filename
. Markdown-Include will work recursively, so any included files within filename
will also be included. This replacement is done prior to any other Markdown processing, so any Markdown syntax that you want can be used within your included files. Note that this is a change from the previous version. It was felt that this syntax was less likely to conflict with any code fragments present in the Markdown.
By default, all file-names are evaluated relative to the location from which Markdown is being called. If you would like to change the directory relative to which paths are evaluated, then this can be done by specifying the extension setting base_path
.
You can also define specific lines or line ranges to include by specifying lines
:
{!filename!lines=1 3 8-10 2}
lines
takes a sequence of integers separated by spaces (one or more), or it can also take line ranges specified with a start line and an end line separated by a dash (-
).
In the example above, it would read the file called filename
and include the lines 1
, 3
, 8
, 9
, 10
, 2
.
Notice that line 9
was not explicitly set. But it was still included as part of the range 8-10
.
Also, notice that line 2
is set after the range 8-10
. This means that the line 2
in filename
will be included after (below) the range 8-10
.
You can use this to include lines in a different order than the original file. But it also means that if you want to preserve the original order, you have to pay attention to the order in which you specify the lines.
ConfigurationThe following settings can be specified when initialising the plugin.
An example of setting the base path and file encoding is given below:
import markdown from markdown_include.include import MarkdownInclude # Markdown Extensions markdown_include = MarkdownInclude( configs={'base_path':'/srv/content/', 'encoding': 'iso-8859-1'} ) html = markdown.markdown(source, extensions=[markdown_include])
Included files can inherit the heading depth of the location inheritHeadingDepth
, as well as receive a specific offset, headingOffset
For example, consider the files
Source file # Heading Level 1 of main file {!included_file.md!} ## Heading Level 2 of main file {!included_file.md!}
and included_file.md
# This heading will be one level deeper from the previous heading More included file content. End of included content.
Then running the script
import markdown from markdown_include.include import MarkdownInclude # Markdown Extensions markdown_include = MarkdownInclude( configs={'inheritHeadingDepth':True} ) html = markdown.markdown(source, extensions=[markdown_include])
produces
<p>Source file</p> <h1>Heading Level 1 of main file</h1> <h2>This heading will be one level deeper from the previous heading</h2> <p>More included file content.</p> <p>End of included content.</p> <h2>Heading Level 2 of main file</h2> <h3>This heading will be one level deeper from the previous heading</h3> <p>More included file content.</p> <p>End of included content.</p>ChangeLog Version 0.7.0

Version 0.6.0Bugfix for a syntax error.
Version 0.5Corrected some errors in documentation and merged in commits of diegobz to add support for encoding and tidy up the source code.
Version 0.4Fixed problem related to passing configurations to the extension.
Version 0.3Added support for Python 3.
Version 0.2Changed the API to be less likely to conflict with other syntax.
Version 0.1Initial release.
