So far inspired by JSON.tmLanguage.json in the VS Code repository, let's see if we can get it to highlight just a constant and maybe an array. |

Grammars
The grammar directory contains various versions of the RCL
grammar, as well as plugins and extensions for editors and other tools to add
support for RCL. If you are interested in using those, see the
syntax highlighting chapter.
The source of truth for RCL's grammars are the lexer and parser in
src/lexer.rs and src/parser.rs. These contain a hand-written lexer
and recursive descent parser. The parser produces a concrete syntax tree
(CST) and the same parser is shared by the evaluator and
autoformatter.
Bison
In bison there is a Bison grammar. It can be compiled to check for errors,
but the goal is not to be used directly; the goal is to provide a readable yet
precise specification of the grammar, and to act as an aid in designing the
grammar, to avoid making ad-hoc decisions in the hand-written parser that are
difficult to parse with more general tools.
Tree-sitter
The tree-sitter-rcl directory contains a Tree-sitter grammar that forms the
basis of various editor integrations. It has its own chapter.
Editor integrations
The following directories contain editor-specific extensions:
