6 Perl::PrereqScanner::NotQuiteLite - a tool to scan your Perl code for
7 its prerequisites
8
10 use Perl::PrereqScanner::NotQuiteLite;
11 my $scanner = Perl::PrereqScanner::NotQuiteLite->new(
12 parsers => [qw/:installed -UniversalVersion/],
13 suggests => 1,
14 perl_minimum_version => 1,
15 );
16 my $context = $scanner->scan_file('path/to/file');
17 my $requirements = $context->requires;
18 my $recommends = $context->recommends;
19 my $suggestions = $context->suggests; # requirements in evals
20 my $noes = $context->noes;
21
23 Perl::PrereqScanner::NotQuiteLite is yet another prerequisites scanner.
24 It passes almost all the scanning tests for Perl::PrereqScanner and
25 Module::ExtractUse (ie. except for a few dubious ones), and runs
26 slightly faster than PPI-based Perl::PrereqScanner. However, it doesn't
27 run as fast as Perl::PrereqScanner::Lite (which uses an XS lexer).
28
29 Perl::PrereqScanner::NotQuiteLite also recognizes "eval".
30 Prerequisites in "eval" are not considered as requirements, but you can
31 collect them as suggestions.
32
33 Conditional requirements or requirements loaded in a block are treated
34 as recommends. Noed modules are stored separately (since 0.94). You
35 may or may not need to merge them into requires.
36
37 Perl::PrereqScanner::NotQuiteLite can also recognize some of the new
38 language features such as "say", subroutine signatures, and postfix
39 dereferences, to improve the minimum perl requirement (since 0.9905).
40
42 new
43 creates a scanner object. Options are:
44
45 parsers
46 By default, Perl::PrereqScanner::NotQuiteLite only recognizes
47 modules loaded directly by "use", "require", "no" statements, plus
48 modules loaded by a few common modules such as "base", "parent",
49 "if" (that are in the Perl core), and by two keywords exported by
50 Moose family ("extends" and "with").
51
52 If you need more, you can pass extra parser names to the scanner,
53 or ":bundled", which loads and registers all the parsers bundled
54 with this distribution. If you have your own parsers, you can
55 specify ":installed" to load and register all the installed
56 parsers.
57
58 You can also pass a project-specific parser (that lies outside the
59 "Perl::PrereqScanner::NotQuiteLite::Parser" namespace) by
60 prepending "+" to the name.
61
62 use Perl::PrereqScanner::NotQuiteLite;
63 my $scanner = Perl::PrereqScanner::NotQuiteLite->new(
64 parsers => [qw/+PrereqParser::For::MyProject/],
65 );
66
67 If you don't want to load a specific parser for some reason,
68 prepend "-" to the parser name.
69
70 suggests
71 Perl::PrereqScanner::NotQuiteLite ignores "use"-like statements in
72 "eval" by default. If you set this option to true,
73 Perl::PrereqScanner::NotQuiteLite also parses statements in "eval",
74 and records requirements as suggestions.
75
76 recommends
77 Perl::PrereqScanner::NotQuiteLite usually ignores "require"-like
78 statements in a block by default. If you set this option to true,
79 Perl::PrereqScanner::NotQuiteLite also records requirements in a
80 block as recommendations.
81
82 perl_minimum_version
83 If you set this option to true, Perl::PrereqScanner::NotQuiteLite
84 adds a specific version of perl as a requirement when it finds some
85 of the new perl language features.
86
87 scan_file
88 takes a path to a file and returns a ::Context object.
89
90 scan_string
91 takes a string, scans and returns a ::Context object.
92
94 Perl::PrereqScanner, Perl::PrereqScanner::Lite, Module::ExtractUse
95
96 Perl::PrereqScanner::NotQuiteLite::App to scan a whole distribution.
97
98 scan-perl-prereqs-nqlite is a command line interface of the above.
