Edit File: throw
# Throw an exception. # The first argument is a string giving the exception. Other arguments # are ignored. # # This is designed to be called somewhere inside a "try-block", i.e. # some code of the form: # { # # try-block # } always { # # always-block # } # although as normal with exceptions it might be hidden deep inside # other code. Note, however, that it must be code running within the # current shell; with shells, unlike other languages, it is quite easy # to miss points at which the shell forks. # # If there is nothing to catch an exception, this behaves like any # other shell error, aborting to the command prompt or abandoning a # script. # The following must not be local. typeset -g EXCEPTION="$1" readonly THROW if (( TRY_BLOCK_ERROR == 0 )); then # We are throwing an exception from the middle of an always-block. # We can do this by restoring the error status from the try-block. (( TRY_BLOCK_ERROR = 1 )) fi # Raise an error, but don't show an error message. THROW= 2>/dev/null
