Hi all,
just for the fun of it, I eval'd:
(setq treesit-language-source-alist
'((python . ("https://github.com/tree-sitter/tree-sitter-bash.git"))
(markdown . ("https://github.com/ikatyang/tree-sitter-markdown.git"))
(rust . ("https://github.com/tree-sitter/tree-sitter-rust.git"))
(elisp . ("https://github.com/Wilfred/tree-sitter-elisp.git"))))
and did `M-x treesit-install-language-grammar RET LANG RET' four times
with languages above. I'm on Win10, so Emacs built 4 .dll files and put
them under ~/.emacs.d/tree-sitter/ -- that went smooth. In order to
make this more convenient for others, would it make sense to preset this
variable with parsers available from this site[1]?
Further, it seems to me that this is a user-settable variable, so I'd
suggest to make it customizable.
Best, Arash

If I am understanding the situation correctly, this is impossible due to
GNU's policy against nonfree things in general. Someone might be able
to find the ML thread discussing this.
Best,

Sorry, no. This was already discussed, and the decision was not to
populate the variable by default, so as not to increase our
maintenance burden. Making grammar libraries available for Emacs
users is the job of downstream distros, not ours. We have enough on
our plate already.

It isn't supposed to be a defcustom, as it's supposed to be populated
as you compile libraries.

Ah, sorry, I must have missed that discussion.

Ok, thanks.

How to compile for langs like "tsx", which requires different value for
"sourcedir" and "grammardir" in the helper build.sh script?

,----[ C-h v treesit-language-source-alist RET ]
| treesit-language-source-alist is a variable defined in ‘treesit.el’.
|
| Its value is nil
|
| Configuration for downloading and installing tree-sitter language grammars.
|
| The value should be an alist where each element has the form
|
| (LANG . (URL REVISION SOURCE-DIR CC C++))
|
| Only LANG and URL are mandatory. LANG is the language symbol.
| URL is the Git repository URL for the grammar.
|
| REVISION is the Git tag or branch of the desired version,
| defaulting to the latest default branch.
|
| SOURCE-DIR is the relative subdirectory in the repository in which
| the grammar’s parser.c file resides, defaulting to "src".
|
| CC and C++ are C and C++ compilers, defaulting to "cc" and
| "c++", respectively.
|
`----
IIUC, SOURCE-DIR is what you're looking for. Something like this should
do the trick:
(setq treesit-language-source-alist
'((tsx . ("https://github.com/tree-sitter/tree-sitter-typescript.git"
nil "tsx/src"))))
Best, Arash
