#!/usr/bin/perl =head1 NAME dh_python3-ply - generate versioned dependencies on python3-ply =cut use strict; use warnings; use Debian::Debhelper::Dh_Lib; =head1 SYNOPSIS B<dh_python3-ply> [B<--dependency-field> I<dependencyfield>] [S<I<debhelper options>>] I<file>... =head1 DESCRIPTION B<dh_python3-ply> is a debhelper program that is responsible for generating the B<python3-ply:Depends> substitutions and adding them to substvars files. The program will look only at Python3 modules that are explicitly provided as its arguments, and will use this information to generate a strict versioned dependency on B<python3-ply>. =head1 OPTIONS =over 4 =item B<--dependency-field> I<dependencyfield> Use B<python3-ply:>I<dependencyfield> substitution variable instead of B<python3-ply:Depends>. =back =cut my $dependency_field = "Depends"; init(options => { "dependency-field:s" => \$dependency_field }); if (not @ARGV) { error("at least one argument is required") } foreach my $filename (@ARGV) { open FILE, $filename or error("cannot read $filename: $!"); read FILE, $_, 1024; my $is_lextab = /^_lextokens\b/m; my $is_parsetab = /^_lr_method\b/m; $is_lextab or $is_parsetab or error("$filename doesn't look like a PLY table"); (my $tabversion) = /^_tabversion\s*=\s*'([0-9.]+)'/m or error("$filename was generated by a very old PLY"); my $dependency = sprintf "python3-ply-%s-%s", $is_lextab ?
