NAME

Sub::Todo - mark subroutines or methods as 'TODO'

VERSION

This document describes Sub::Todo version 0.0.3

SYNOPSIS

    use Sub::Todo;

    sub foo {
            return 'foo';
    }

    sub bar {
            goto &todo; 
    }

    *baz = \&todo_croak;

Then in your app:

   bar() or die "bar() failed: $!";  
   baz();

Which reminds you "oh yeah, we need to do this still"

DESCRIPTION

At times you want to/need to/should write the flow of logic without having to break to create the actual functions or methods being used. You can create them as temporary 'TODO's by goto()ing any of these 'todo' utilities (see INTERFACE).

EXPORT

todo() is exported by default, the rest can be exported, ':all' will export them all, ':long' will export the "long" disambiguously named functions.

INTERFACE

These are made to be used with goto() (see SYNOPSIS). They set $! and 'return;'

todo()

set $! and return

todo_return()

Same as todo() but the name is more descriptive

todo_carp()

Same as todo() but it additionally 'carp $!;'

todo_croak()

Same as todo() but it additionally 'croak $!;'

get_errno_func_not_impl()

This is used internally to set $!.

It should determine the correct value from POSIX if you've used POSIX, based on the OS name, or a semi-safe default.

DIAGNOSTICS

Throws no real errors or warnings of its own. Except todo_carp() and todo_croak() which throw $!

If $! is not 'Function not implemented' please open an rt with this information:

  • The output of this command:

      perl -MPOSIX -le 'print "-$^O-";print "-" . POSIX::ENOSYS . "-"';
  • Does adding 'use POSIX;' get $! set properly?
