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

my $ret = err_bt_pretty(@errors);
my @ret = err_bt_pretty(@errors);

Get string or array with full backtrace. 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

Returns string with full backtrace in scalar context. Returns array of full backtrace lines in array context.

err_bt_pretty_rev

my $ret = err_bt_pretty_rev(@errors);
my @ret = err_bt_pretty_rev(@errors);

Reverse version of print for err_bt_pretty(). 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

Returns string with full backtrace in scalar context. Returns array of full backtrace lines in array context.

err_line

my $ret = err_line(@errors);

Get 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

Returns string.

err_line_all

my $ret = err_line_all(@errors);

Get 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

Returns string.

err_print

my $ret = err_print(@errors);

Print first error. If error comes from class, print class name before error.

Returns string with error.

err_print_var

Print first error with all variables.

Returns error string in scalar mode. Returns lines of error in array mode.
