NAME Module::XSOrPP - Determine if an installed module is XS or pure-perl VERSION This document describes version 0.06 of Module::XSOrPP (from Perl distribution Module-XSOrPP), released on 2014-12-05. SYNOPSIS use Module::XSOrPP qw( is_xs is_pp ); say "Class::XSAccessor is an XS module" if is_xs("Class/XSAccessor.pm"); say "JSON::PP is a pure-Perl module" if is_pp("JSON::PP"); DESCRIPTION FUNCTIONS is_xs($mod, \%opts) => BOOL Return true if module $mod is an XS module, false if a pure Perl module, or undef if can't determine either. $mod value can be in the form of "Package/SubPkg.pm" or "Package::SubPkg". The following ways are tried, in order: * Looking at the ".packlist" If a .{bs,so,dll} file is listed in the ".packlist", then it is assumed to be an XS module. This method will fail if there is no ".packlist" available (e.g. core or uninstalled or when the package management strips the packlist), or if a dist contains both pure-Perl and XS. * Looking at the source file for usage of "XSLoader" or "DynaLoader" If the module source code has something like "use XSLoader;" or then it is assumed to be an XS module. This is currently implemented using a simple regex, so it is somewhat brittle. * Guessing from the name If the module has "XS" in its name then it's assumed to be an XS module. If the module has "PP" in its name, it's assumed to be a pure-Perl module. Known false positives will be prevented in the future. Other methods will be added in the future (e.g. a database like in Module::CoreList, consulting MetaCPAN, etc). Options: * warn => BOOL (default: 0) If set to true, will warn to STDERR if fail to determine. * debug => BOOL (default: 0) If set to true will print debugging message to STDERR. is_pp($mod, \%opts) => BOOL The opposite of "is_xs", return true if module $mod is a pure Perl module.
