error. ( error -- )
Factor handbook » The language » Exception handling » The debugger

Prev:	try ( quot -- )
Next:	:error ( -- )

Vocabulary
debugger

Inputs

error

an error

Outputs
None

Generic word contract
Print an error to output-stream. You can define methods on this generic word to print human-readable messages for custom errors.

Notes
Code should call print-error instead, which handles the case where the printing of the error itself throws an error.
