Module parser 

Bash AST parser wrapper around tree-sitter-bash.

Converts tree-sitter’s raw [tree_sitter::Node] graph into a friendlier Node tree that the security analyzer consumes. All offsets are UTF-8 byte offsets and Node::text is sliced directly from the original source so callers never have to manage tree-sitter lifetimes themselves.

Structs

Node

A node in the bash AST.

SimpleCommand

A simple command with its argv, leading environment assignments, and redirects.

Enums

RedirectOp

A redirect operator canonical enum.

Constants

ARGUMENT_KINDS

Kinds that are considered literal words / arguments.

DANGEROUS_KINDS

Named node kinds that represent compound / dynamic shell constructs. If any of these appear in a command, we refuse to extract a static argv.

STRUCTURAL_KINDS

Kinds that wrap multiple commands.

Functions

is_argument_kind

Returns true if the node kind is an argument-like token.

is_command_kind

Returns true if the node kind is a command name or declaration command.

parse

Parse a bash command string into an AST.

parse_variable_assignment

Simple field-name to value map for a variable_assignment node.

redirect_op_from_kind

Maps a tree-sitter redirect operator kind to its canonical form.
