feature: "==" text highlighting. #188
Description
Did you check the tree-sitter docs?
- I have read all the tree-sitter docs if it relates to using the parser
Is your feature request related to a problem? Please describe.
Many widely used markdown editors support using ==highlight text==. It would be nice if this was supported directly through tree-sitter-markdown
Describe the solution you'd like
Add an extension highlight group that captures ==text between double equal signs==.
Describe alternatives you've considered
It is possible to manually add it as a highlight group.
For my specific case obsidian.nvim has a feature for this, except it is buggy and the whole plugin is quite bloated.
Additional context
If people think this has merit I could attempt to create a PR for this, although I am quite inexperienced in writing tree-sitter grammars.
