[Bug 1181183] Re: Add support for the Ubuntu SDK apps to dh_translations

Hello Olivier, David,

Ack, then it might indeed be simpler to just put everything into
dh_translations.

Ah, so that's a different issue from the original report here (that
building the .pot doesn't work).

Oliver said about this:

Is the i18n.tr() call Ubuntu specific, or does it apply to all QML
apps? In the latter case, it seems easier to just check if the package
has any *.qml files, and activate the xgettext call based on this? But
I guess that's not generally sufficient, as Ubuntu SDK (or QML apps
in general) might also have C++ files which use the standard _()
convention?

Thanks,

Martin

Title:
  Add support for the Ubuntu SDK apps to dh_translations

Status in “pkgbinarymangler” package in Ubuntu:
  Incomplete

Bug description:
  dh_translations, when it builds a POT file from the source files, invokes intltool-update, which in turn invokes xgettext to extract the translatable strings from the source files.
  By default, xgettext looks for a set of predefined keywords to identify translatable strings.
  This set of predefined keywords doesn’t include "i18n.tr", which is the function used in QML files that use the Ubuntu SDK.
  As a result, no strings are found, and no POT file is generated.

  Ideally, dh_translations should support passing (arbitrary?) extra
  options to intltool-update/xgettext. Or at least extend the default
  list of keywords to support the apps written with the Ubuntu SDK.
