NAME

App::abgrep - Print lines matching a pattern

VERSION

This document describes version 0.006 of App::abgrep (from Perl distribution App-abgrep), released on 2020-11-07.

FUNCTIONS

abgrep

Usage:

abgrep(%args) -> [status, msg, payload, meta]

Print lines matching a pattern.

This is a grep-like utility that is based on AppBase::Grep, mainly for demoing and testing the module. The unique features include multiple patterns and --dash-prefix-inverts.

This function is not exported.

Arguments ('*' denotes required arguments):

  • all => true

    Require all patterns to match, instead of just one.

  • color => str

  • count => true

    Supress normal output, return a count of matching lines.

  • dash_prefix_inverts => bool

    When given pattern that starts with dash "-FOO", make it to mean "^(?!.*FOO)".

    This is a convenient way to search for lines that do not match a pattern. Instead of using -v to invert the meaning of all patterns, this option allows you to invert individual pattern using the dash prefix, which is also used by Google search and a few other search engines.

  • files => array[filename]

  • ignore_case => bool

  • invert_match => bool

    Invert the sense of matching.

  • line_number => true

  • pattern => str

  • quiet => true

  • regexps => array[str]

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
