How to run lupdate with a QMAKE CONFIG?

devjb

I posted the same question on stackoverflow after a few days:

https://stackoverflow.com/questions/58029996/how-to-run-qts-lupdate-tool-with-a-qmake-config

.

I use such a construct in my project files:

LANGUAGES = de
TRANSLATION_NAME = authorization
include(../../gen_translations.pri)

where gen_translations.pri looks like so:

# parameters: var, prepend, append
defineReplace(prependAll) {
 for(a,$$1):result += $$2$${a}$$3
 return($$result)
}

TRANSLATIONS = $$prependAll(LANGUAGES, $$PWD/libs/$$TRANSLATION_NAME/translations/lib$${TRANSLATION_NAME}_, .ts)

TRANSLATIONS_FILES =

qtPrepareTool(LRELEASE, lrelease)

for(tsfile, TRANSLATIONS) {
 qmfile = $$shadowed($$tsfile)
 qmfile ~= s,.ts$,.qm,
 qmdir = $$dirname(qmfile)
 !exists($$qmdir) {
 mkpath($$qmdir)|error("Aborting.")
 }
 command = $$LRELEASE -removeidentical $$tsfile -qm $$qmfile
 system($$command)|error("Failed to run: $$command")
 TRANSLATIONS_FILES += $$qmfile
}

for(qmentry, $$list($$TRANSLATIONS_FILES)) {
  qmpath = $$OUT_PWD/../translations
  qmpathname = $$replace(qmpath,/,)
  qmpathname = $$replace(qmpathname,\.,)
  qmpathname = $$replace(qmpathname,:,)
  qmpathname = $$replace(qmpathname," ",)
  qmentity = qmfiles_$${qmpathname}
  eval($${qmentity}.files += $$qmentry)
  eval($${qmentity}.path = $$qmpath)
  INSTALLS *= $${qmentity}
}

It generates the *.qm files for me and moves them to a defined location with make install.

I do not want qmake to execute that whole stuff for each build on my developing machine. Therefore I want to make the stuff conditional by wrapping it for qmake:

translate{
LANGUAGES = de
TRANSLATION_NAME = authorization
include(../../gen_translations.pri)
}

That way I can decide when I want to get *.qm files and when not.
But then I am unable to run lupdate on the project file because it is blocked by that conditional.

I am sure, that someone has a better idea to accomplish the task.

Thanks in advance.
