Crate bash_ast 

Typed AST over tree-sitter-bash.

tree-sitter gives back a stringly-typed CST (node.kind() == "command"); this crate converts that into a Rust enum tree so downstream consumers (permission rules, linters, refactors) can pattern-match instead of comparing strings.

The typed surface mirrors tree-sitter-bash’s node-types.json one-to-one: every named node kind has a corresponding variant. Conversion is total — an unrecognized node kind returns ParseError::UnknownNode rather than being silently dropped.

Modules

ast

Typed AST for bash, mirroring tree-sitter-bash’s node-types.json 1:1.

summary

High-level summary extracted from a parsed bash Program.

tier

Danger-tier classifier over the bash AST (R459-T1).

tool_invocation

ToolInvocation extraction from a PeeledCommand (R295-F1).

wrappers

Shared wrapper-command set + peel logic (R155-T9).

Enums

ParseError

Functions

parse

Parse bash source into a tree-sitter CST. Useful when callers want to walk the raw CST themselves; most consumers want parse_to_ast instead.

parse_to_ast

Parse bash source and convert to the typed AST. Returns an error if any node kind is unrecognized (we treat unknown kinds as a bug rather than silently dropping them, so the typed surface stays in lockstep with the grammar).
