Perl::PrereqScanner::NotQuiteLite - a tool to scan your Perl code for its prerequisites
use Perl::PrereqScanner::NotQuiteLite; my $scanner = Perl::PrereqScanner::NotQuiteLite->new( parsers => [qw/:installed -UniversalVersion/], suggests => 1, perl_minimum_version => 1, ); my $context = $scanner->scan_file('path/to/file'); my $requirements = $context->requires; my $recommends = $context->recommends; my $suggestions = $context->suggests; # requirements in evals my $noes = $context->noes;
Perl::PrereqScanner::NotQuiteLite is yet another prerequisites scanner. It passes almost all the scanning tests for Perl::PrereqScanner and Module::ExtractUse (ie. except for a few dubious ones), and runs slightly faster than PPI-based Perl::PrereqScanner. However, it doesn't run as fast as Perl::PrereqScanner::Lite (which uses an XS lexer). Perl::PrereqScanner::NotQuiteLite also recognizes "eval". Prerequisites in "eval" are not considered as requirements, but you can collect them as suggestions. Conditional requirements or requirements loaded in a block are treated as recommends. Noed modules are stored separately (since 0.94). You may or may not need to merge them into requires. Perl::PrereqScanner::NotQuiteLite can also recognize some of the new language features such as "say", subroutine signatures, and postfix dereferences, to improve the minimum perl requirement (since 0.9905).
new creates a scanner object. Options are: parsers By default, Perl::PrereqScanner::NotQuiteLite only recognizes modules loaded directly by "use", "require", "no" statements, plus modules loaded by a few common modules such as "base", "parent", "if" (that are in the Perl core), and by two keywords exported by Moose family ("extends" and "with"). If you need more, you can pass extra parser names to the scanner, or ":bundled", which loads and registers all the parsers bundled with this distribution. If you have your own parsers, you can specify ":installed" to load and register all the installed parsers. You can also pass a project-specific parser (that lies outside the "Perl::PrereqScanner::NotQuiteLite::Parser" namespace) by prepending "+" to the name. use Perl::PrereqScanner::NotQuiteLite; my $scanner = Perl::PrereqScanner::NotQuiteLite->new( parsers => [qw/+PrereqParser::For::MyProject/], ); If you don't want to load a specific parser for some reason, prepend "-" to the parser name. suggests Perl::PrereqScanner::NotQuiteLite ignores "use"-like statements in "eval" by default. If you set this option to true, Perl::PrereqScanner::NotQuiteLite also parses statements in "eval", and records requirements as suggestions. recommends Perl::PrereqScanner::NotQuiteLite usually ignores "require"-like statements in a block by default. If you set this option to true, Perl::PrereqScanner::NotQuiteLite also records requirements in a block as recommendations. perl_minimum_version If you set this option to true, Perl::PrereqScanner::NotQuiteLite adds a specific version of perl as a requirement when it finds some of the new perl language features. scan_file takes a path to a file and returns a ::Context object. scan_string takes a string, scans and returns a ::Context object.
Perl::PrereqScanner, Perl::PrereqScanner::Lite, Module::ExtractUse Perl::PrereqScanner::NotQuiteLite::App to scan a whole distribution. scan-perl-prereqs-nqlite is a command line interface of the above.
