NAME App::ScanPrereqs - Scan files/directories for prerequisites VERSION This document describes version 0.005 of App::ScanPrereqs (from Perl distribution App-ScanPrereqs), released on 2019-07-31. SYNOPSIS # Use via lint-prereqs CLI script FUNCTIONS scan_prereqs Usage: scan_prereqs(%args) -> [status, msg, payload, meta] Scan files/directories for prerequisites. Examples: * By default scan current directory: scan_prereqs(); This is an alternative CLI to scan_prereqs, with the following features: * merged output scan_prereqs by default reports prereqs per source file, which may or may not be what you want. This CLI outputs a single list of prerequisites found from all input. Aside from that, you can use "--json" to get a JSON output. * option to pick backend Aside from Perl::PrereqScanner you can also use Perl::PrereqScanner::Lite and Perl::PrereqScanner::NotQuiteLite. * filter only core or non-core prerequisites. This function is not exported. Arguments ('*' denotes required arguments): * files => *array[pathname]* (default: ["."]) * perlver => *str* Perl version to use when determining core/non-core. The default is the current perl version. * scanner => *str* (default: "regular") Which scanner to use. "regular" means Perl::PrereqScanner which is PPI-based and is the slowest but has the most complete support for Perl syntax. "lite" means Perl::PrereqScanner::Lite uses an XS-based lexer and is the fastest but might miss some Perl syntax (i.e. miss some prereqs) or crash if given some weird code. "nqlite" means Perl::PrereqScanner::NotQuiteLite which is faster than "regular" but not as fast as "lite". Read respective scanner's documentation for more details about the pro's and con's for each scanner. * show_core => *bool* (default: 1) Whether or not to show core prerequisites. * show_noncore => *bool* (default: 1) Whether or not to show non-core prerequisites. 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) HOMEPAGE Please visit the project's homepage at .
