Tree-sitter support for C and C++
This package provides major modes for C and C++, plus some handy
functions that are useful generally to major modes for C-like
languages.
This package provides `c-ts-mode' for C, `c++-ts-mode' for C++, and
`c-or-c++-ts-mode' which automatically chooses the right mode for
C/C++ header files.
To use these modes by default, assuming you have the respective
tree-sitter grammars available, do one of the following:
- If you have both C and C++ grammars installed, add
(require 'c-ts-mode)
to your init file.
- Add one or mode of the following to your init file:
(add-to-list 'major-mode-remap-alist '(c-mode . c-ts-mode))
(add-to-list 'major-mode-remap-alist '(c++-mode . c++-ts-mode))
(add-to-list 'major-mode-remap-alist '(c-or-c++-mode . c-or-c++-ts-mode))
If you have only C grammar available, use only the first one; if
you have only the C++ grammar, use only the second one.
- Customize 'auto-mode-alist' to turn one or more of the modes
automatically. For example:
(add-to-list 'auto-mode-alist
'("\\(\\.ii\\|\\.\\(CC?\\|HH?\\)\\|\\.[ch]\\(pp\\|xx\\|\\+\\+\\)\\|\\.\\(cc\\|hh\\)\\)\\'"
. c++-ts-mode))
will turn on the c++-ts-mode for C++ source files.
You can also turn on these modes manually in a buffer. Doing so
will set up Emacs to use the C/C++ modes defined here for other
files, provided that you have the corresponding parser grammar
libraries installed.
