Title: One string not translated for unknown reason
Post by: Roland57 on November 27, 2021, 11:00:27 am
Hello!

I use PO files for this project (https://gitlab.com/rchastain/mater/-/tree/master/gui). This is the first time I use PO files.

All my strings are correctly translated, excepted one which is always displayed in English.

The only difference that I can see with the other strings of the project is that this string has several lines, and that I use an included file.

Code: Pascal  [Select][+][-]
  1. (* aboutform.pas *)
  2. resourcestring
  3.   ReadMeText = {$I readme};
  4.   BTCloseCaption = 'Close';
  5.   FormCaption = 'About Mater GUI';

Code: Pascal  [Select][+][-]
  1. (* readme.pas *)
  2.   '' + LineEnding +
  3.   'Mater GUI %s' + LineEnding +
  4.   '' + LineEnding +
  5.   'Graphical user interface for Valentin Albillo''s mate searching program.' + LineEnding +
  6.   '' + LineEnding +
  7.   'Uses Chest by Heiner Marxen as auxiliary search engine.' + LineEnding +
  8.   '' + LineEnding +
  9.   'For Linux, uses Chest 3.19 (1). For Windows, uses WinChest by Heiner Marxen and Franz Huber (2).' + LineEnding +
  10.   '' + LineEnding +
  11.   '(1) http://turbotm.de/~heiner/Chess/chest.html' + LineEnding +
  12.   '(2) https://fhub.jimdofree.com'
  13.  

The included file is automatically generated from a .txt file that I edit by hand. That's why I do like that.

If someone who has more experience than I do with PO files would take a look, or has an idea why it doesn't work...

Regards.

Roland

If that was of any concern, you must see a difference if you substituted the {$I} with the file’s contents.

I checked out what messages you got (https://gitlab.com/rchastain/mater/-/blob/master/gui/po/matergui.de.po) and noticed readMeText is the only message containing newlines. This might be the culprit of your problem, that the msgids don’t match because of different encoding of newlines.

@Kays

Thank you for your answer.

I replaced "LineEnding" with "#10", and pasted the code directly in the file: the problem is still here.

You might want to have a look at this (http://www.gnu.org/software/gettext/manual/html_node/PO-Files.html) 'official' doc on handling po strings. Do a Ctrl-F on 'remainder' and read on. However, I don't know if it's implemented with the Lazarus version of GetText as well. But worth a try.

Thanks. I have read that page. I didn't find an explanation to my problem.

Hello Roland.

Not sure if it helps but did you try with "#13" or "#10#13" ?

Just did a quick test, put a TLabel on a form, entered a two line caption and enabled i18n. Resulting po file had:

Code: Text  [Select][+][-]
  1. #: tfrmmain.label1.caption
  2. msgid ""
  3. "Line1\n"
  4. "Line2\n"
  5. msgstr ""

Translated this caption as:

Code: Text  [Select][+][-]
  1. #: tfrmmain.label1.caption
  2. msgid ""
  3. "Line1\n"
  4. "Line2\n"
  5. msgstr ""
  6. "Zeile1\n"
  7. "Zeile2\n"

included the po file like this (https://forum.lazarus.freepascal.org/index.php/topic,57203.0.html) and it worked. Which also answers the question if Lazarus has this implemented...

So just try \n for line endings.

Do you mean \n directly in my Pascal string? Otherwise I don't see what you mean.

My .po file looks like yours.

Code: Text  [Select][+][-]
  1. #: aboutform.readmetext
  2. msgctxt "aboutform.readmetext"
  3. msgid ""
  4. "\n"
  5. "Mater GUI %s\n"
  6. "\n"
  7. "Graphical user interface for Valentin Albillo's mate searching program.\n"
  8. "\n"
  9. "Uses Chest by Heiner Marxen as auxiliary search engine.\n"
  10. "\n"
  11. "For Linux, uses Chest 3.19 (1). For Windows, uses WinChest by Heiner Marxen and Franz Huber (2).\n"
  12. "\n"
  13. "(1) http://turbotm.de/~heiner/Chess/chest.html\n"
  14. "(2) https://fhub.jimdofree.com\n"
  15. msgstr ""
  16. "\n"
  17. "Mater GUI %s\n"
  18. "\n"
  19. "Interface graphique pour le programme de recherche de mat de Valentin Albillo.\n"
  20. "\n"
  21. "Utilise Chest de Heiner Marxen comme moteur de recherche auxiliaire.\n"
  22. "\n"
  23. "Pour Linux, Mater GUI utilise Chest 3.19 (1). Pour Windows, Mater GUI utilise WinChest de Heiner Marxen et Franz Huber (2).\n"
  24. "\n"
  25. "(1) http://turbotm.de/~heiner/Chess/chest.html\n"
  26. "(2) https://fhub.jimdofree.com\n"

By the way, I wonder why some messages have a "message context", while the other don't.

@Fred

Thanks, I will try.

What is aboutform.readmetext, a resourcestring or part of the lfm? What does it look like where it's defined?

Sorry, forgot about that...  :-[   But your setup works for me...?

Edith: including simple sample project, uses ResTrans (https://forum.lazarus.freepascal.org/index.php/topic,57203.0.html) package, however. Created with 2.0.10.

Weird. For me it doesn't work. But it is not so important after all.  :)

Hello Roland.

Afaik, gettext does not like when msgid  begins with "":

Code: Pascal  [Select][+][-]
  1. msgctxt "aboutform.formcaption"
  2. msgid ""
  3. "Mater GUI %s\n"
  4. "\n"
  5.  

Just begin with this:

Code: Pascal  [Select][+][-]
  1. msgid "Mater GUI %s\n"
  2. "\n"

And also in the translated po file, add the original code in msgid "here original code"

Also in the readme, remove the first empty line.

Included update po files, here it (seems) to work.

PS: Maybe  :-[

Thanks. Your project works here. And I see no difference with mine until now. I will continue to search.

Just one more idea: check whether the encoding of your po file still is UTF8. I seem to recall some weird effects if for some reason any editor might have mixed that up.

Hello Roland.

I am testing too and strangely, a mastergui.pot generated file is created with msgid "" at begin.

Strange.

Code: [Select]
msgid ""
"Mater GUI %s\n"
"\n"
"Graphical user interface for Valentin Albillo's mate searching program.\n"
"\n"
"Uses Chest by Heiner Marxen as auxiliary search engine.\n"
"\n"
"For Linux, uses Chest 3.19 (1). For Windows, uses WinChest by Heiner Marxen and Franz Huber (2).\n"
"\n"
"(1) http://turbotm.de/~heiner/Chess/chest.html\n"
"(2) https://fhub.jimdofree.com"
msgstr ""

BTW, Roland, which Lazarus version are you on? I remember some changes in the help system regarding line endings some time ago.

[EDIT]
Using Laz/main I recreated the po files (Run/Build) and translated the aboutform.readmetext to German. When I copy the .de.mo file to the locale folder the text is still English, but when I copy the .de.po file I see my translation.

Yes, with the po files it works. Good point!

May I have your German translation?   O:-)

@Sieben

So I see now why your sample project works: it also uses PO files.

I changed the project options, to save the PO files directly in locale folder, and no longer compile to MO. Problem solved.
