Feature request: Please support custom slug/anchor/id definition #1529
Description
Proposal
Please support custom slug/anchor/id definition. Example:
# This is my heading {#this-is-my-own-slug}
Currently, custom slugs are not supported, resulting in the following TOC:
- [1. This is my heading {#this-is-my-own-slug}](#1-this-is-my-heading-this-is-my-own-slug)
# 1. This is my heading {#this-is-my-own-slug}
If custom slugs were supported, the TOC would look like this:
- [1. This is my heading](#this-is-my-own-slug)
# 1. This is my heading {#this-is-my-own-slug}
Other information
This can be very useful in multiple cases, for examle:
- Having one site in idfferent languages, but with the same slugs/anchor/ids allows to stay in the same region of the document when switching between languages manually or automatically.
- Creating slugs which are shorter than the whole text of the heading, or totally differ from it
At least pandoc, kramdown, Hugo and Jekyll support custom slugs.
