Markdown Table Of Contents

Automatically generate a compliant table of contents for a markdown file to improve document readability.




The table of contents (a.k.a: TOC) generated by this program is designed to work with several markdown parsers such as the ones used by GitHub and GitLab.

When used with the in-place option this script will write the TOC at the first occurrency of a marker. The default marker is <!--TOC-->, which, being an HTML comment, will result invisible after the markdown file has been translated.

By default titles up to three indentation levels (in HTML: h1, h2, h3) will be included in the TOC but the user can decide to keep all possible levels.

md_toc makes it is possible to generate ordered and unordered TOCs. In both cases each element of the TOC is by default a link to a paragraph in the web page. It is also possible to generate a non-linked version of the TOC.

If the user wants it, there is the possibility to ignore space indentations within the TOC and to skip an initial number of lines from the markdown file.

Rules for generating the TOC are determined by the selected markdown parser. md-toc aimes infact to be as conformant as possible in respect to each one of them. This was possible by studying the available documentations and by reverse engineering the source codes.


Please read carefully the Markdown specification section of the documentation to learn how this program parsers markdown files and builds a correct output.

API examples

md-toc has a public API. This means for example that you can you easily build a TOC within another Python program. The easiest way to build one for a markdown file is:


>>> import md_toc
>>> f = open('')
>>> print(, end='')
# this
## is
## a
### foo
#### booo
### foo
## file

## bye

# bye
>>> print(md_toc.build_toc(''), end='')
- [this](#this)
  - [is](#is)
  - [a](#a)
    - [foo](#foo)
    - [foo](#foo-1)
  - [file](#file)
  - [bye](#bye)
- [bye](#bye-1)
