Perl::Metrics::Simple - Count packages, subs, lines, etc. of many files.
use Perl::Metrics::Simple; my $analyzer = Perl::Metrics::Simple->new; my $analysis = $analyzer->analyze_files(@paths, @refs_to_file_contents); $file_count = $analysis->file_count; $package_count = $analysis->package_count; $sub_count = $analysis->sub_count; $lines = $analysis->lines; $main_stats = $analysis->main_stats; $file_stats = $analysis->file_stats;
Perl::Metrics::Simple provides just enough methods to run static analysis of one or many Perl files and obtain a few metrics: packages, subroutines, lines of code, and an approximation of cyclomatic (mccabe) complexity for the subroutines and the "main" portion of the code.
Perl::Metrics::Simple is far simpler than Perl::Metrics.
Installs a script called countperl.
See the countperl script (included with this distribution) for a simple example of usage.
Takes no arguments and returns a new Perl::Metrics::Simple object.
Takes a path and returns true if the target is a Perl file.
Takes an array of files and or directory paths, and/or SCALAR refs to file contents and returns an Perl::Metrics::Simple::Analysis object.
Uses list_perl_files to find all the readable Perl files and returns a reference to a (possibly empty) list of paths.
Takes a list of one or more paths and returns an alphabetically sorted list of only the perl files. Uses is_perl_file so may throw an exception if a file is unreadable.
Takes a path to a file and returns true if the file appears to be a Perl file, otherwise returns false.
If the file name does not match any of @Perl::Metrics::Simple::PERL_FILE_SUFFIXES then the file is opened for reading and the first line examined for a a Perl 'shebang' line. An exception is thrown if the file cannot be opened in this case.
Returns true if the path should be skipped when looking for Perl files. Currently skips .svn, CVS, and _darcs directories.
