NAME ^

PPIx::Grep - Search PPI documents (not Perl code).

VERSION ^

This document describes PPIx::Grep version 0.0.6.

SYNOPSIS ^

    use PPIx::Grep qw< run set_print_format >;

    set_print_format('%f> %s\n');  # Yes, single quotes.
    my $return_code = run( qw< include lib/PPIx/Grep.pm > );

DESCRIPTION ^

This is the guts of ppigrep. You're most likely more interested in that.

INTERFACE ^

Nothing is exported by default, but you can import everything using the :all tag.

run(@ARGV)

Parse command-line options, find PPI elements, and emit the results.

Returns the expected exit value for the program. This value is equivalent to the one for grep. If a match was found, this is 0. If no match was found, this is 1. And if any problems occurred, this is 2.

set_stdout($destination)

Specifies where the regular output will go.

set_stderr($destination)

Specifies where the error output will go.

set_match($regex)

Sets the pattern that elements will be matched against. This needs to be a compiled regex and not merely a string.

set_print_format($format)

Sets the format to be used to emit an individual PPI::Element. Note that newlines are not automatically printed for each Element; if you want them, you need to specify them as part of the parameter.

DIAGNOSTICS ^

Could not figure out what PPI class to use for "%s".

The pattern argument could not be resolved to a subclass of PPI::Element via PPIx::Shorthand.

Could not find any PPI::Element subclasses to use for "%s".

The pattern argument didn't resolve to any PPI::Element subclasses. Did you specify the empty string?

Invalid regex "%s": %s.

The regex specified via --match could not be compiled.

"%s" does not exist.

Cannot find the file.

"%s" is not readable.

Cannot read the file.

"%s" is a directory.

The "file" was actually a directory.

Could not parse "%s".

PPI could not interpret the file as a Perl document.

CONFIGURATION AND ENVIRONMENT ^

None, currently.

DEPENDENCIES ^

Getopt::Long List::MoreUtils PPI::Document PPIx::Shorthand String::Format

INCOMPATIBILITIES ^

None reported.

BUGS AND LIMITATIONS ^

· This thing is way too limited in functionality.

Please report any bugs or feature requests to bug-ppix-grep@rt.cpan.org, or through the web interface at http://rt.cpan.org.
