Hi Mr Fai!

das variablen-script, von dem ich auf dem Workshop geredet habe ist fertig, das ergebnis sieht auf meinem Testbaum so aus:

$VAR1 = {

         '$sd' => [
                    'task_mountdisks'
                  ],
         '$name' => [
                      'defnop'
                    ],
         '$thislog' => [
                         'save_log_local',
                         'save_log_remote_shell'
                       ],
         '$DO_INIT_TASKS' => [
                               'task_confdir',
                               'task_extrbase',
                               'task_setup',
                               'task_action',
                               'task_faiend'
                             ]
   };


Das Script selbst so:


#! /usr/bin/perl -w

use strict;
use File::Find;
use English;
my $dir = "/usr/lib/fai";
my @files;
my $klammerRegex;
$klammerRegex = qr/
 \{
   (
     [^{}] | (??{ $klammerRegex })
   )*
 \} 
/sx;

sub wanted;

# Traverse desired filesystems
find({wanted => \&wanted},$dir);

sub wanted {
    my ($dev,$ino,$mode,$nlink,$uid,$gid);
    return if m/.deb$/;

    (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) &&
    -f _
    && push @files,$File::Find::name;
}

my %variables;
my ($fai_variable,$key,$value,$var);

for (@files) {
    chomp $_;
    local $/;
    my $file;
    PrivoxyWindowOpen(FILE,"<$_",) or die "can't open $_: $!";
    while (<FILE>) {
	$file="$file$_";
	}

    while ($file =~ m/(\w+)\(\)\s+$klammerRegex/gsx){
	my $function = $MATCH;
	my $functionName = $1;
	while ($function =~ m/\$\w+/gs) {
	    my $variable = $MATCH;
	    $variables{$variable} = []
 		unless exists $variables{"$variable"};
	    my $MATCHED=0;
	    foreach (@{ $variables{"$variable"} }) {
		if ( $_ eq $functionName) {
		    $MATCHED=1;
		}
	    }
  	    push (@{ $variables{"$variable"} }, $functionName)
		     unless $MATCHED==1;
	}
    }
    close(FILE); 
} 

# Wenn man es nicht im dumper format haben will
#foreach $var ( keys %variables ){
#    print "$var:\t@{ $variables{$var} }\n";
#}
use Data::Dumper;
print Dumper \%variables;


Die nächste Version soll alle Variablen noch selbst extrahieren können, aber einen Überblick bekommt man zumindest erstmal.

documentation incomplete

The list is incomplete. E.g. SWAPLIST is available in FAI 4.0.6 ThomasNeumann 22:10, 2 March 2013 (UTC)
