NAME
App::ScanPrereqs - Scan source code for prerequisites
VERSION
This document describes version 0.004 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 source code for prerequisites.
Examples:
By default scan current directory:
scan_prereqs();
This is an alternative CLI to scan_prereqs. This CLI offers alternate backends: aside from Perl::PrereqScanner you can also use Perl::PrereqScanner::Lite and Perl::PrereqScanner::NotQuiteLite. Some other features: output in various formats (text table, JSON), 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 thanregular
but not as fast aslite
.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)
