`dis`

Disassemble code objects, functions, and source strings into a human-readable instruction listing. Used by debuggers and the traceback formatter.

Source-of-record: Lib/dis.py, dis docs.

Functions

Function	Effect
`dis(x=None, *, file=None, depth=None, show_caches=False, adaptive=False, show_offsets=False, show_positions=False)`	Disassemble any.
`disassemble(co, lasti=-1, *, file=None, show_caches=False, adaptive=False)`	Single code object.
`distb(tb=None, *, file=None)`	Last traceback.
`get_instructions(x, *, first_line=None, show_caches=False, adaptive=False)`	Iterator.
`findlinestarts(code)` / `findlabels(code)`	Source map / jump targets.
`code_info(x)`	Multi-line summary.
`show_code(x, *, file=None)`	Print summary.
`stack_effect(opcode, oparg=None, *, jump=None)`	Stack delta.

Class	Fields
`Instruction`	`opname`, `opcode`, `arg`, `argval`, `argrepr`, `offset`, `start_offset`, `starts_line`, `is_jump_target`, `positions`, `cache_offset`, `end_offset`.
`Bytecode(x, *, first_line=None, current_offset=None, show_caches=False, adaptive=False, show_offsets=False)`	`dis()`, `info()`, iteration.
`Positions`	`lineno`, `end_lineno`, `col_offset`, `end_col_offset` (PEP 657).

Area	State
`dis`, `disassemble`, `distb`	Complete; uses gopy opcode set.
`get_instructions`, `Bytecode`	Complete.
`Positions`, PEP 657 columns	Complete.
`stack_effect`	Complete.
`show_caches` / `adaptive`	Reflects gopy specialiser; partial.
