internationalisation is broken again

[SingingBush]

I have .po files in a project which had worked for years but noticed today that at some point the internationalisation has stopped working. This was also a problem back in 2016, see: #1555

We should definitely make sure that a test case ends up in the test suite this time if it is caused by a bug. My guess though is that this is caused by introducing context strings in diet-ng: rejectedsoftware/diet-ng#92

The fact that this breaks existing PO files is very unfortunate, maybe this needs a compatibility transition phase.

thanks for the quick response. I've looked at PR #2585 so can now see what needs to be changed re msgctxt. Could it perhaps default to some kind of global context?

[SingingBush]

This has become a bit of a problem. When I have translations that are only used on a single page, using msgctxt is fine.

msgctxt "index"
msgid "home.welcome-message"
msgstr "Welcome to the site"

but for text that is needed all over the site, such as "Submit" being on the button of a form I've not found a way to define the string once and access it from multiple pages. I saw the use of a trWeb function in /examples/web-i18n/views/home.dt but it didn't work for me.

One way would be to outsource the submit button to either an "extends" or "include" template. The context should always be the original source code file and not the top level one being compiled.

ok thanks
