[PyQt] Qt Linguist and pylupdate4: project layout and paths in my_software_*.ts

[Jérôme]

Hi all.

I'm writing a PyQt4 project and I'm having a hard time with the
translation features.

My project is structured as follows:

------------------------------------------------------------------------------------

src/
    my_software.py
    my_software.pro
    my_software/
        module_1.py
        module_2.py
            submodule_1/
                submodule_1_module_1.py
                submodule_1_module_2.py
    resources/
        ui/
            module_1.ui
            module_2.ui
            submodule_1/
                submodule_1_module_1.ui
                submodule_1_module_2.ui
    i18n/
        ts/
            my_software_fr.ts
            my_software_fr.qm
tools/
    tool_1.py

------------------------------------------------------------------------------------

The project file looks like :

-- my_software.pro
-----------------------------------------------------------------

FORMS = resources/ui/module_1.ui resources/ui/module_2.ui
resources/ui/submodule_1_module_1.ui
resources/ui/submodule_1_module_2.ui
SOURCES = my_software/module_1.py my_software/module_2.py
resources/ui/submodule_1_module_1.py
resources/ui/submodule_1_module_2.py
TRANSLATIONS = i18n/ts/my_software_fr.ts

------------------------------------------------------------------------------------

When I call pylupdate4 and lrelease on my_software.pro, I get the .ts
and .qm files created. Fine.

The only shortcoming right now is Qt Linguist doesn't display the
context: it searches for the files in e.g.

/absolute/path/to/project/src/i18n/ts/my_software/module_1.py

The .ts file looks like

-- my_software_fr.ts
---------------------------------------------------------------

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE TS>
<TS version="2.0" language="fr_FR">
<context>
    <name>Class</name>
    <message>
        <location filename="my_software/module_1.py" line="134"/>
        <source>Source text</source>
        <translation>Translated text</translation>

------------------------------------------------------------------------------------

and apparently, Qt Linguist considers relative paths starting from the
.ts file, not the .pro file.

How can I get Qt Linguist to display the source code ?

I can put the .pro file in the ts/ directory. In fact, I wouldn't mind.
I only use it for translation purposes, and my scripts create it and
erase it each time I need a translation update. But is this how it is
meant to be ?

Considering Qt Linguist's behaviour, shouldn't pylupdate4 write paths in
the .ts file relative to the .ts file itself, rather than the .pro file
?

Remarks :

- The C++ version of lupdate has an --absolute|relative flag that might
be related to this.

- I don't wan't to maintain my_software.pro, so I created scripts to
generate it and do the pylupdate4 and lrelease calls.

- This project layout might not be the most sensible. I searched the
web, found different ways of doing this and used a mix of them. I'm open
to suggestions. I'm trying to do things the way they should, rather than
find a workaround to my specific issue.

Thanks for any help.
