https://github.com/tree-sitter
To compile such a library, compile the files "scanner.c" and "parser.c"
(sometimes named "scanner.cc" and "parser.cc") in the "src" subdirectory
of the library's source tree using the C or C++ compiler, then link
these two files into a shared library named "libtree-sitter-LANG.so",
where LANG is the name of the language supported by the grammar as it
is expected by the Emacs major mode (for example, "c" for 'c-ts-mode',
"cpp" for 'c++-ts-mode', "python" for 'python-ts-mode', etc.). Then place
the shared library you've built in the same directory where you keep
the other shared libraries used by Emacs, or in the "tree-sitter"
subdirectory of your 'user-emacs-directory', or in a directory
mentioned in the variable 'treesit-extra-load-path'.
You only need to install language grammar libraries required by the
Emacs modes you will use, as Emacs loads these libraries only when the
corresponding mode is turned on in some buffer for the first time in
an Emacs session.
Emacs provides a user command, 'treesit-install-language-grammar',
that automates the download and build process of a grammar library.
It prompts for the language, the URL of the language grammar's VCS
repository, and then uses the installed C/C++ compiler to build the
library and install it.
You can also do this manually. To compile such a library after
cloning its Git repository, compile the files "scanner.c" and
"parser.c" (sometimes named "scanner.cc" and "parser.cc") in the "src"
subdirectory of the library's source tree using the C or C++ compiler,
then link these two files into a shared library named
"libtree-sitter-LANG.so", where LANG is the name of the language
supported by the grammar as it is expected by the Emacs major mode
(for example, "c" for 'c-ts-mode', "cpp" for 'c++-ts-mode', "python"
for 'python-ts-mode', etc.). Then place the shared library you've
built in the same directory where you keep the other shared libraries
used by Emacs, or in the "tree-sitter" subdirectory of your
'user-emacs-directory', or in a directory mentioned in the variable
'treesit-extra-load-path'.
