Crate rl_lang 

rl_lang - the core library crate.

Re-exports all subsystems so both the CLI binary (main.rs) and external consumers (LSP, tests, benchmarks) can reach them through one crate.

Feature flags gate optional subsystems:

Feature	Enables
eval	checker, interpreter
repl_tui	repl
lsp	[lsp]
debug	verbose log:: output throughout the pipeline

Modules

ast

Abstract Syntax Tree (AST) node definitions.

checker

Static type checker for rl - runs after parsing, before evaluation.

docs

In-process documentation system for the rl docs CLI command.

interpreter

The rl tree-walking interpreter.

lexer

The lexer - converts raw source text into a flat Vec<Token>.

logic_loops

Pipeline driver functions.

parser

The parser - transforms a flat Vec<Token> produced by the lexer into a Vec<Statement> that represents the abstract syntax tree (AST).

repl

TUI REPL for rl, built on [ratatui] and [crossterm].

resolver

Variable resolution pass - runs between parsing and evaluation.

tooling

Tooling support for rl projects.

utils

Shared utilities used across the rl pipeline.
