NAME
    Test::NoBreakpoints - test that files do not contain soft breakpoints

VERSION
    version 0.14

SYNOPSIS
     use Test::NoBreakpoints;
     plan tests => $num_tests;
     no_breakpoints_ok( $file, 'Contains no soft breakpoints' );

    Module authors can include the following in a t/nobreakpoints.t file to
    add such checking to a module distribution:

      use Test::More;
      eval "use Test::NoBreakpoints 0.10";
      plan skip_all => "Test::NoBreakpoints 0.10 required for testing" if $@;
      all_files_no_breakpoints_ok();

DESCRIPTION
    I love soft breakpoints ("$DB::single = 1") in the Perl debugger.
    Unfortunately, I have a habit of putting them in my code during
    development and forgetting to take them out before I upload it to CPAN,
    necessitating a hasty fix/package/bundle cycle followed by much cursing.

    Test::NoBreakpoints checks that files contain neither the string
    "$DB::single = 1" nor "$DB::signal = 1". By adding such a test to all my
    modules, I swear less and presumably lighten the load on the CPAN in
    some small way.

FUNCTIONS
    Unless otherwise noted, all functions are tests built on top of
    Test::Builder, so the standard admonition about having made a plan
    before you run them apply.

  no_breakpoints_ok($file, [$description] )
    Checks that $file contains no breakpoints. If the optional $description
    is not passed it defaults to "no breakpoint test of $file".

    If the test fails, the line number of the file where the breakpoint was
    found will be emitted.

    For compatibility with old versions of this module, the deprecated name
    "no_brkpts_ok" may also be used (but see "DEPRECATED FUNCTIONS").

  all_perl_files( [@dirs] )
    Returns a list of all *.pl, *.pm and *.t files in the directories
    listed. If @dirs is not passed, defaults to "blib" and "t".

    The order of the files returned is machine-dependent. If you want them
    sorted, you'll have to sort them yourself.

  all_files_no_breakpoints_ok( [@files] )
    Checks all files that look like they contain Perl using
    no_breakpoints_ok(). If @files is not provided, it defaults to the
    return of all_perl_files().

    For compatibility with old versions of this module, the deprecated name
    "all_files_no_brkpts_ok" may also be used (but see "DEPRECATED
    FUNCTIONS").

EXPORTS
    By default all_files_no_breakpoints_ok and no_breakpoints_ok.

    For the time being, the deprecated forms the above
    (all_files_no_brkpts_ok and no_brkpts_ok) are also exported (but see
    "DEPRECATED FUNCTIONS").

    On request, all_perl_files.

    Everything with the tag :all.

DEPRECATED FUNCTIONS
    Prior to v0.13 of this module, no_breakpoints_ok was called no_brkpts_ok
    and all_files_no_breakpoints_ok was similarly abbreviated.

    In v0.13, these older names were deprecated. They are still exported by
    default, but will emit a warning unless you disable the deprecated
    lexical warning category:

      {
        no warnings 'deprecated';
        no_brkpts_ok(...);
      }

    In the next release, the deprecated functions will have to be pulled in
    via an import tag. In the release after that, they will cease to be.

    the logic of all_perl_files from.

BUGS
    *   doesn't catch some breakpoints

        This is a valid breakpoint:

          package DB;
          $single = 1;
          package main;

        as is this:

          my $break = \$DB::single;
          $$break = 1;

        but neither are currently caught.

TODO
    *   enhance regex to find esoteric setting of breakpoints

        If you have a legitimate breakpoint set that isn't caught, please
        send me an example and I'll try to augment the regex to match it.

    *   only look at code rather than the entire file

        This is not as easy as simply stripping out POD, because there might
        be inline tests or examples that are code in there (using
        Test::Inline). Granted, those should be caught when the generated .t
        files are themselves tested, but I'd like to make it smarter.

    *   not use regular expressions

        The ideal way to find a breakpoint would be to compile the code and
        then walk the opcode tree to find places where the breakpoint is
        set. B::FindAmpersand does something similar to this to find use of
        the $& in regular expressions, so this is probably the direction I'm
        going to head in.
