Documentation

Decoration level to be used by tree-sitter fontifications.

Major modes categorize their fontification features into levels, from 1 which is the absolute minimum, to 4 that yields the maximum fontifications.

Level 1 usually contains only comments and definitions. Level 2 usually adds keywords, strings, data types, etc. Level 3 usually represents full-blown fontifications, including assignments, constants, numbers and literals, etc. Level 4 adds everything else that can be fontified: delimiters, operators, brackets, punctuation, all functions, properties, variables, etc.

In addition to the decoration level, individual features can be turned on/off by calling treesit-font-lock-recompute-features. Changing the decoration level requires calling treesit-font-lock-recompute-features to have an effect, unless done via customize-variable.

To see which syntactical categories are fontified by each level in a particular major mode, examine the buffer-local value of the variable treesit-font-lock-feature-list.

This variable was added, or its default value changed, in Emacs 29.1.
