  a structural diff that understands syntax 🟥🟩

Semantic Diff is probably the closest for now, although I don't think it uses tree-sitter.

• tree-sitter-embedded-template

  2 51 4.2 C

  Tree-sitter grammar for embedded template languages like ERB, EJS

  

That may require a tree-sitter implementation for erb templated html; it may exist but if so it's less of a mainstream thing.

Some quick googling turns up https://github.com/tree-sitter/tree-sitter-embedded-template which may or may not meet your needs.

  An incremental parsing system for programming tools

  

Tree-sitter optimizes for performance (to use in editors), not for correctness. In fact even TS' core developers advocate for not bothering too much with correctness of grammars[1]. I imagine this constraint would be a deal-breaker for GitHub or anyone else in their position.

• mise

  dev tools, env vars, task runner

direnv + mise does exactly that. When I cd to various directories I get different env vars, it's pretty neat. Setting aliases would just be a case of adding them.

https://github.com/jdx/mise/discussions/1525 for an example of how I use direnv with mise.

• vim-surround

  surround.vim: Delete/change/add parentheses/quotes/XML-tags/much more with ease

I don't know what exactly you mean by pasting around the second selection, but you can paste selections, registers or even files at specific lines with some vim-fu. If it's generic enough you could write a function or even keyboard shortcut if it's very simple.

I have set ",',(,[,{ in visual mode to cut the selection insert the pairs then paste it back as a very hacky solution, but it gets the job done. If you want something more advanced to add or change anything around the selection tpope has solved that with vim-surround[1].

  C++ grammar for tree-sitter

  

Grammar page (https://github.com/tree-sitter/tree-sitter-cpp) reference two documents at the very end:

- Hyperlinked C++ BNF Grammar (https://alx71hub.github.io/hcb/)

- EBNF Syntax: C++ (ISO/IEC 14882:1998(E)) https://www.externsoft.ch/download/cpp-iso.html

The second doc has a year in the title, so it's ancient af.

  Good-lookin' diffs. Actually… nah… The best-lookin' diffs. :tada:

  

The diff itself is impressive, but in terms of styling I still prefer diff-so-fancy[1]. It's easier to read at a glance.
