treesitter
would be an interesting experiment, as you've outlined it.
an LSP would be cool indeed. we definitely want to add a LSP to nushell but we're not there yet. luckily, we have @jntrnr who worked on rust's RLS, i believe. we just need a jt.clone() function to get everything done.

One of the ways I can think of achieving this is by using treesitter
. With that, we should have even better highlighting, considering it can do syntax highlighting based on an AST instead of regex-based highlighting (which ig is the popular option at present).
I don't really know how to integrate treesitter
with reedline
(that is something we will need to figure out).
Though I would wager the harder part would have been writing the parser for nu-shell
. (Luckily for us it already exists - https://github.com/LhKipp/tree-sitter-nu).
And for other popular languages, there are already parsers, so if bash/fish/sh or any other shells decide to use reedline
they should get this for little work.
Note: in addition to syntax highlighting we can also get stuff like
- context-aware rename
- text objects (like block, function, etc), (e.g. someone using vim mode can do stuff like
cib
which can meanchange in block
) - etc.
Absolutely random thought: as for the drop-down menu, I don't really know how to achieve this with the UI, but if we want to do something overkill we can integrate an LSP client (https://github.com/ebkalderon/tower-lsp) to readline
so that it can do anything that an editor can.
Now the creation of a language server is going to be hard, but my assumption is that the nu-shell folks might already be thinking about it as it can add editor support for almost all the ones that people use.
