Module shell_parser 

Shell script parser for bash -lc and similar commands.

This module parses shell commands like:

bash -lc "git status && cargo check"

Into individual command vectors for independent safety checking:

[["git", "status"], ["cargo", "check"]]

Phase 4 Implementation: Uses tree-sitter for accurate bash AST parsing. Falls back to basic tokenization for minimal shell syntax.

Functions

parse_bash_lc_commands

Parses bash -lc "script" style invocations

parse_shell_commands

Parses a shell script into individual commands using tree-sitter bash grammar

parse_shell_commands_tree_sitter

Parses a shell script using tree-sitter bash grammar only (no fallback tokenization).

prewarm_bash_parser

Ensures the bash tree-sitter parser is initialized.
