This package requires Emacs 29 built with tree-sitter support.
To check if your Emacs has tree-sitter support check
(treesit-available-p)This package does not automatically install the grammar yet.
A compatible tree-sitter Eiffel grammar is available at
https://github.com/imustafin/tree-sitter-eiffel. The compatible version is
v1.0.0.
Emacs will look for the compiled grammar in the following paths:
- first, in the list of directories specified by the variable
treesit-extra-load-path;- then, in the
tree-sittersubdirectory of the directory specified byuser-emacs-directory(see The Init File);- and finally, in the system’s default locations for dynamic libraries. https://www.gnu.org/software/emacs/manual/html_node/elisp/Language-Grammar.html
The user-emacs-directory is ~/.emacs.d by default, so putting
libtree-sitter-eiffel.so in ~/.emacs.d/tree-sitter/ is enough.
This package is not available in any package archives yet.
