NAME

   Glib::FindMinVersion - Find minimum version of GLib needed to compile C
   source

SYNOPSIS

       use Glib::FindMinVersion;

       print Glib::FindMinVersion::with('g_get_num_processors'); # 2.36
       print scalar Glib::FindMinVersion::for_file('source.c'); # 2.18
       my %symbols = Glib::FindMinVersion::for_file('source.c' => 2.10);
       # (
       #   2.18 => [qw[g_set_error_literal]],
       #   2.12 => [qw[g_ascii_strtoll g_base64_decode]],
       # )


IMPLEMENTATION

   Symbol use is detected quite crudely with / \s* (?<symbol>\w+) \s* \(
   /x. Symbols introduced prior to 2.0 are labelled as 2.0.

METHODS AND ARGUMENTS

   with(@symbols)

     Returns minimum GLib version which exports all @symbols.

   for_source($source [, $version])

     Here, [] denotes an optional argument. In list context, returns a
     listing of all found glib symbols grouped by version. If $version is
     given, the list is limited to symbols newer than $version. $version
     is a string of the form /2\.\d\d?/.

     In scalar context, returns the maximum version in the list, which is
     the minimum version required to use all the symbols.

   for_file($filename [, $version])

     Helper function that reads in $filename and passes it to for_source.

NAMING

   Official casing is GLib, but there's a Glib module already on CPAN, so
   this follows suit. This and the Glib module are unrelated though.
