NAME

Devel::DidYouMean - Intercepts failed function and method calls, suggesting the nearest matching alternative.

VERSION

version 0.02

SYNOPSIS

#!/usr/bin/env perl
# somescript.pl
use Data::Dumper;
require Devel::DidYouMean;

print Dumpr($data); # wrong function name
...

*Run the code*

$ somescript.pl
Undefined subroutine 'Dumpr' not found in main. Did you mean Dumper? at somescript.pl line 6.

Or add as a one liner:

$ perl -Ilib -mData::Dumper -MDevel::DidYouMean -e 'Data::Dumper::Dumpr($data)'
Undefined subroutine 'Dumpr' not found in Data::Dumper. Did you mean Dumper? at -e line 1.

Maybe trap the error and extract the matching subs for something else

use Try::Tiny;

try
{
    sprintX("", $text); # boom
}
catch
{
    my $error_msg = $_;
    my @closest_matching_subs = @$Devel::DidYouMean::DYM_MATCHING_SUBS;
    ...
}

DESCRIPTION

Devel::DidYouMean intercepts failed function and method calls, suggesting the nearest matching available subroutines in the context in which the erroneous function call was made.

WARNING

This library is experimental, on load it exports an AUTOLOAD subroutine to every namespace in the symbol table. Therefore it should be loaded last in your program, preferably using require.

THANKS

This module was inspired by Yuki Nishijima's Ruby gem did_you_mean.

SEE ALSO

Symbol::Approx::Sub is a similar module that catches invalid subroutine names and then executes the nearest matching subroutine it can find. It does not export AUTOLOAD to all namespaces in the symbol table.
