Module interpreter 

Interpreter engine: parsing, AST walking, and execution state.

Structs

CallFrame

A single frame on the function call stack, used to expose FUNCNAME, BASH_SOURCE, and BASH_LINENO arrays.

ExecResult

Result of executing a shell command.

ExecutionCounters

Execution counters, reset per exec() call.

ExecutionLimits

Execution limits.

FunctionDef

Stub for function definitions (execution in a future phase).

InterpreterState

The interpreter’s mutable state, persistent across exec() calls.

ShellOpts

Shell options controlled by set -o / set +o and single-letter flags.

ShoptOpts

Shopt options (shopt -s/-u flags).

Variable

A shell variable with metadata.

VariableAttrs

Attribute flags for a shell variable.

Enums

ControlFlow

Signal for loop control flow (break, continue) and function return.

VariableValue

The value stored in a shell variable: scalar, indexed array, or associative array.

Functions

builtin_names

Return the list of known shell builtin names.

execute_program

Execute a parsed program.

expand_word

Expand a word into a list of strings (with IFS splitting on unquoted parts).
