Table of Contents

Overview

Easy and customizable way to generate TOC for README.md on GitHub.

  • Automatically generate table of contents in accordance with Github Favored Markdown format
  • Just a single .py file can be done with no other dependencies
  • Support for text content in both Chinese and English languages
  • Support for customizing the header level of the table of contents
  • Supports automatic write results to files, and also can print results to standard output for further processing
  • Supports generating table of contents for multiple files at the same time
  • Support for repeating headers, filtering headers in code blocks

If you don't want to download any files or read the command instructions below, you can try my online build tool.

Installation

Pypi

$ pip3 install gfm-toc --upgrade

Manually

$ git clone https://github.com/waynerv/github-markdown-toc
$ cd github-markdown-toc
$ python3 setup.py install

You can also directly download the file gfm_toc/md_toc.py in the repository and run this script manually like this:

$ python3 md-toc.py [-h] [-s {1,2,3,4,5,6}] [-e {1,2,3,4,5,6}] [-o] file [file ...]

Usage

The command syntax is as follows:

$ gfm-toc [-h] [-s {1,2,3,4,5,6}] [-e {1,2,3,4,5,6}] [-o] file [file ...]

Run the command as follows to get help information for the command options(you can replace -h with --help).:

$ gfm-toc -h

Note: Make sure your device has successfully installed Python3 before run it.

Single file

Automatically generate TOC for a single markdown file and print result to standard output with only 2-4 title levels:

$ gfm-toc -s 2 -e 4 -o README_eng.md
Generate from file: README_eng.md

Table of contents generated.

Then copy/paste result between prompt sentence from console into original README.md.

Multiple files

Use the default configuration to generate TOC for multiple markdown files and write them to a file separately:

$ gfm-toc file01.md file02.md file03.md
Table of contents generated.

Here's an example:

After generating TOC and writing to the file:

Configuration

customize the header level

Use the command line options -s or --start and add parameters to set the start header level of TOC. The default value of the parameter is 1.

Use the command line options -e or --end and add parameters to set the end header level of TOC. The default value of the parameter is 6.

The title level parameter must be an integer between 1 and 6, and the start header level cannot be greater than the end header level.

-s {1,2,3,4,5,6}, --start {1,2,3,4,5,6}  choose the start level of TOC, default value is 1
-e {1,2,3,4,5,6}, --end {1,2,3,4,5,6}  choose the end level of TOC, default value is 6

Generate TOC of 1-6 header levels (default option):

$ gfm-toc test/Mastering_Markdown.md -o
Generate from file: test/Mastering_Markdown.md

Only generate 2-3 header levels:

$ gfm-toc examples/Mastering_Markdown.md -o -s 2 -e 3
Generate from file: examples/Mastering_Markdown.md

Write results to a file or print to standard output

By default, the program automatically writes the generated TOC to the beginning of the original file.

Add the option -o or --output when you want to print the results to standard output for copying or other processing.

-o, --output          print toc to stdout instead of writing to file

Use the > on the command line to export the generated directory to a separate file:

$ gfm-toc -o README.md > table_of_content.md

Add a title to the generated TOC

This option is not very common, because in many cases, people write Markdown documents according to different specifications or their own habits. But if you need, you can add -t or --title options when executing commands. This will add a level 2 header called Table of contens to the generated TOC, as follows:

$ gfm-toc examples/Mastering_Markdown.md -o -s 2 -e 3 -t
Generate from file: examples/Mastering_Markdown.md
