giscus VS tree-sitter-comment

That project also has Github issues and discussions pages to ask questions and get help.

When creating my blog-centric personal portfolio, I had a goal of launching it as soon as possible. However, considering including a comment feature, the implementation process could be time-consuming. That's when I started looking for a solution that was easy to set up yet provided essential commenting functionalities. It was during this search that I stumbled upon Giscus.

But now, a new fellow named giscus commenting system has entered the town, it's basically powered by github. Since I already host my blog on github pages, this should be a natural choice for me, right? Many bloggers seem to be migrating to this new system and I might too soon. The downsides however are as follows:

Get Giscus here.

Supports Giscus - a comments system powerd by Github Discussions.

I've encountered https://github.com/utterance/utterances, which relies on github issues for providing a blog comments system of a sort.

Alternatively there's https://github.com/giscus/giscus, which instead uses github discussions.

Haven't used either so can't comment (heh) on their "performance".

There's also a recent similar tool called https://github.com/giscus/giscus that uses Github Discussions as the backing system, rather than Issues.

As far as I know there is currently no treesitter parser for Doxygen style comments. There is a language agnostic comment parser that is supported by nvim-treesitter that will highlight things like TODO: and NOTE: in comments. Until this recent commit nvim-treesitter provided a query for this parser that highlighted @ text in comments. It was meant to highlight a reference to a user but it doubled as a doxygen tag highlight for me for a while. I just noticed that this query has been removed and I'm not sure why but you can add it as a custom query in your Neovim config. I have yet to try this so you'll have to refer to the Neovim treesitter docs for where to add the query.

I'm not sure how to use this in Emacs, but there's also a tree-sitter grammar specifically for comment blocks, including TODOs: https://github.com/stsewd/tree-sitter-comment

you mean this one? https://github.com/stsewd/tree-sitter-comment

The reason I implemented this is because of the slow performance of tree-sitter-comment in large files. Treesitter will inject the comment language for every line comment, which is far from ideal. I've disabled the comment parser, but still wanted to see @something highlighted in Lua comments.

The right most window shows the code I want to query. This is a .cpp file, so the main-language is C++. For highlighting the two comments, I'm using tree-sitter-comment. This plugin injects the comment-language. I want to query all tag nodes from this injected language, but this query does not work.

You can install this parser for treesitter which highlights comments :)
