Reading Embeded PO Files

CMELIGM:
Hello,

i am using PO Files to translate my Application and so far it all works out like expected. i recently embeded my po Files into the Executable using project settings -> resources.

i am currently extracting the files from the executable again when using it:

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---initialization ForceDirectories(Application.Location + 'languages'); ExtractResource('MyApplication.DE', 'languages\MyApplication.de.po', true); ExtractResource('MyApplication.EN', 'languages\MyApplication.en.po', true);

and to switch language i use:

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---SetDefaultLang('en', 'languages');
This works but i wonder if there is also a way where i do not have to extract the Files and can directly use them ?. so skip the steps "ExtractResource"

i tried this: "https://wiki.lazarus.freepascal.org/Everything_else_about_translations#Compiling_po_files_into_the_executable_and_change_language_while_running"

but i did not work for me (i also did not fully understand what is going on).

The overhead is almost not there or very low: why would you need that?
I think you can also include the PO files as RT_RCDATA resource entries. Then there is no overhead at all.(just a pointer change)

Bart:
Maybe this unit of mine can give you some pointers?

it would be great to not have the PO Files lying around in the install Folder.

Thank you, this was indeed helpful.

Thaddy:
Tnx Bart for the real life example I was too lazy to provide.
