NAME Error::Pure::Output::Text - Output subroutines for Error::Pure. SYNOPSIS use Error::Pure::Output::Text qw(err_bt_pretty err_bt_pretty_rev err_line err_line_all err_print err_print_var); my $ret = err_bt_pretty(@errors); my @ret = err_bt_pretty(@errors); my $ret = err_bt_pretty_rev(@errors); my @ret = err_bt_pretty_rev(@errors); my $ret = err_line(@errors); my $ret = err_line_all(@errors); my $ret = err_print(@errors); my $ret = err_print_var(@errors); my @ret = err_print_var(@errors); SUBROUTINES "err_bt_pretty(@errors)" Returns string with full backtrace in scalar context. Returns array of full backtrace lines in array context. Format of error is: ERROR: %s %s: %s ... %s %s %s %s ... Values of error are: message message as key, $message as value ... sub, caller, program, line "err_bt_pretty_rev(@errors)" Reverse version of print for err_bt_pretty(). Returns string with full backtrace in scalar context. Returns array of full backtrace lines in array context. Format of error is: ERROR: %s %s: %s ... %s %s %s %s ... Values of error are: message message as key, $message as value ... sub, caller, program, line "err_line(@errors)" Returns string with error on one line. Use last error in @errors structure.. Format of error is: "#Error [%s:%s] %s\n" Values of error are: $program, $line, $message "err_line_all(@errors)" Returns string with errors each on one line. Use all errors in @errors structure. Format of error line is: "#Error [%s:%s] %s\n" Values of error line are: $program, $line, $message "err_print(@errors)" Print first error. If error comes from class, print class name before error. Returns string with error. "err_print_var(@errors)" Print first error with all variables. Returns error string in scalar mode. Returns lines of error in array mode.
