rbtr-lang-less

Less support for rbtr. Optional plugin — install with pip install rbtr[less].

What it ingests

Less extends CSS with the Less preprocessor constructs. Definitions map onto rbtr's capture conventions by shape:

• Variables — @-prefixed declarations (@primary: #333;).
• Routines — .mixin() definitions → functions. Mixin calls are references, not definitions, and are skipped.
• Rule sets & at-rule blocks — selectors, @media, @keyframes → classes (a named collection of declarations).
• Directives — @charset → config key.
• Imports — @import → imports (for cross-file edges).

Chunks produced

name is the declaration/selector; scope is the ancestor rule-set selectors for a nested rule (CSS-family nesting), else empty.

@primary: #333;                /* variable "@primary"                 */
.rounded(@r) { … }             /* function "rounded"                  */
.btn { … }                     /* class ".btn"                        */
@keyframes slide { … }         /* class "slide"                       */
@import "reset";               /* import, metadata {module: "reset"}  */

Embedded / injected chunks

None. Less does not embed other languages.

Grammar & dependencies

Uses the tree-sitter-less grammar. Depends on rbtr-lang-css — it reuses that plugin's public css_nesting_scope helper for CSS-family rule nesting.
