P4::C4::Ignore - Read a cvs ignore file

  use P4::C4::Ignore;

  my $ign = new P4::C4::Ignore();
  $ign->isIgnored ($filename);

  ...

The P4::C4::Ignore package reads .cvsignore files and provides matching functions.

Ignore files are mostly compatible with CVS. The global list of ignores is initialized with:

    *~      #*      .#*     ,*      _$*     *$
    *.old   *.bak   *.BAK   *.orig  *.rej   .del-*
    *.a     *.olb   *.o     *.obj   *.so    *.exe
    *.Z     *.elc   *.ln
    .c4cache     .p4config
    .make.state  .nse_depinfo  .dependency-info
    tags         TAGS
    core

Patterns in the home directory file ~/.cvsignore, or the CVSIGNORE environment variable are appended to this list.

Each directory may have a local '.cvsignore' file. The patterns found in local `.cvsignore' are only valid for the directory that contains them, not for any sub-directories.

In any of the places listed above, a single exclamation mark (`!') clears the ignore list. This can be used if you want to store any file which normally is ignored.

The wildcards * and ? are honored, no other wildcards are currently supported.

$ign = P4::C4::Ignore->new ( opts )

Create a new Ignore hash. "filename=>filename" may be specified to override the default of .cvsignore for reading the ignore file.

Any .cvsignore files that are read are cached in this object to save time. Thus if a .cvsignore file is being written by the application, a new object will have to be created to clear the hash.

$self->is_ignored ( $file )

Returns true if the file is being ignored.
