Translations with subprojects

[django.Reinhard]

Hi,

I migrated a project from Qt5 to Qt6 and read about Qts translation support. But when I issue the command from docs

cmake --build . --target update_translations

it handles only files from top-level project.
My project has many plugins, which I treat as deployable units, which means, each plugin has its own resources and of cause its own ts-files.

How can I use cmake to handle translation command on all subdirectories as well?

I have subdirectories, which contain no sources just CMakefiles for other subdirectories. So iterating over subdirectory definitions is not the solution.

I guess, I could handle it with scripting, but I would prefer a solution that works with cmake.

Any help is appreciated

@OdinUci What does your question have to do with OPs question?
Please open your own thread and formulate your question better.

Hi,

in case someone has similar problems - here's how I solved it:
My CMakeList.txt has these statements:

set(TS_FILES i18n/MyApp_de_DE.ts)
set(PROJECT_SOURCES
    src/main.cpp
    src/MainWindow.h
    src/MainWindow.cpp
    src/MainControl.h
    src/MainControl.cpp
    src/MainWindow.ui
    ${TS_FILES}
    )
qt_add_executable(MyApp
                  MANUAL_FINALIZATION
                  ${PROJECT_SOURCES}
                  AppResources.qrc
                  )

add_subdirectory(src/libModel)
add_subdirectory(src/libService)
add_subdirectory(src/plugins)

plugins directory does not contain any sources but more subdirectories ...

I wrote a perlscript that reads CMakeList.txt and works based on the found informations. It successfully populated the ts-files declared in the plugins.

#!/usr/bin/perl
#
# script to handle translatable texts in projects with nested subprojects
#
use Cwd;


sub readCMake {
  my $fp;
  my $rv;
  my @src, @dirs;

  open($fp, 'CMakeLists.txt') or die('OUPS - can not open cmake configuration!'."\n");
  while (my $line = <$fp>) {
        if ($line =~ /set\(\s*TS_FILES/) {
           print('found TS_FILES -->'.$line."\n");
           my @parts = split(/\(|\s+|\)/, $line);

           $rv->{'fnTS'} = $parts[2] if -e $parts[2];
           }
        elsif ($line =~ /set\(\s*PROJECT_SOURCES/) {
           print('found PS -->'.$line."\n");
           while (my $fnSrc = <$fp>) {
                 $fnSrc =~ s/^\s*(\S+?)\s*$/$1/;
                 push(@src, $fnSrc) if -e $fnSrc;
                 last if $fnSrc =~/\)/;
                 }
           }
        elsif ($line =~ /add_subdirectory\((.*?)\)/) {
           my $d = $1;

           $d = cwd().'/'.$d if not $d =~ /^\//;
           push(@dirs, $d);
           }
        }
  close($fp);
  $rv->{'src'}  = \@src;
  $rv->{'dirs'} = \@dirs;

  return $rv;
  }


sub scan {
  my $cfg = shift;
  my $cmd = 'lupdate '.join(' ', @{$cfg->{'src'}}).' -ts '.$cfg->{'fnTS'};

  print('cmd: '.$cmd."\n");
  system($cmd);
  }


#
# main
#
autoflush STDOUT 1;
my $base = cwd();
my $work = readCMake();
print('TS-File: '.$work->{'fnTS'}."\n");
foreach (@{$work->{'src'}}) {
        print('source file: '.$_."\n");
        }
scan($work);
foreach (@{$work->{'dirs'}}) {
        my $d = $_;

        print('sub-dir: '.$d."\n");
        chdir($d);
        my $wSub = readCMake();

        scan($wSub);
        }

Cheers
