This package provides a major-mode for jq using the tree-sitter grammar for Jq from tree-sitter-jq.

Features:

• indentation
• font-locking
• imenu
• structural navigation with treesitter objects

For a major-mode without tree-sitter see jq-mode.

Emacs 29.1 or above with tree-sitter support is required.

Tree-sitter starter guide: https://git.savannah.gnu.org/cgit/emacs.git/tree/admin/notes/tree-sitter/starter-guide?h=emacs-29

Add the source to treesit-language-source-alist.

(add-to-list
 'treesit-language-source-alist
 '(jq "https://github.com/nverno/tree-sitter-jq"))

Then run M-x treesit-install-language-grammar and select jq to install the shared library.

M-x package-install jq-ts-mode
