Perhaps that should be an or?
Adding (require 'rust-mode)
gets rid of the warning, but the problem remains.
Turning the and
into an or
just makes rust-mode not load at all.
I am reluctant to turn on native tree-sitter mode, as I develop some tree-sitter grammars and have the non-native tree-sitter support enabled.
@alanz When do you actually see that warning that was reported by you ? Is it during installation or during some other step (Your latest comment indicates it's during flycheck) ? I can try reproducing it locally for my setup.
I don't think doing or
is the right thing here.
I agree or is not the right step, it broke completely.
I see the error on starting up emacs. I guess I need to dig more deeply into the actual origin. And/or go full native tree-sitter. I will not be able to do any investigation today though
And it seems the warning is benign, I have the functionality I need regardless.
see the error on starting up emacs.
Looking at my Messages buffer - I can see a similar type of warning:
■ Warning (treesit): Cannot activate tree-sitter, because language grammar for rust is unavailable (not-found): (libtree-sitter-rust libtree-sitter-rust.0 libtree-sitter-rust.0.0 libtree-sitter-rust.so libtree-sitter-rust.so.0 libtree-sitter-rust.so.0.0) No such file or directory
I receiving the warning even though I'm using a tree sitter based setup. Probably it's able to find the grammars subsequently, not sure.
And it seems the warning is benign, I have the functionality I need regardless.
Thanks for the confirmation, I assumed something was broken. Given the situation, I will close this PR. I would be happy to accept any PR that fixes the warning. :-)
FYI, I switched to emacsformacosx, which has tree-sitter support build in. Without explicitly asking for the tree-sitter mode, I am getting
⛔ Warning (treesit): Cannot activate tree-sitter, because language grammar for rust is unavailable (not-found): (libtree-sitter-rust.so libtree-sitter-rust.so.0 libtree-sitter-rust.so.0.0 libtree-sitter-rust.dylib libtree-sitter-rust.dylib.0 libtree-sitter-rust.dylib.0.0) No such file or directory
Which I guess means I need to work out how to install the language. Is it documented somewhere? A quick scan of the README does not show anything
And it looks like the steps are
init.el
(setq treesit-language-source-alist
'((rust "https://github.com/tree-sitter/tree-sitter-rust")
))
In emacs
M-x
treesit-install-language-grammar Pick
rust`
My final piece of barrage.
Putting the following into my init.le
(use-package rust-ts-mode
:custom
(rust-mode-treesitter-derive t)
...
)
...
(use-package lsp-mode
:hook (rust-mode rust-ts-mode)
...
)
And basically using rust-ts-mode
instead of rust-mode
in all config restored
This does not work for me. When I apply it locally, flycheck reports that
rust-mode-treesitter-derive)
is not defined
