pygettext generates output even when there should be none #133049
Description
Bug report
Bug description:
This occurs in two cases:
- Output is still generated when there is no input. Whereas
xgettext:And the second case follows on from this (but can also occur with input files)$ xgettext xgettext: no input file given Try 'xgettext --help' for more information. - In
xgettext, no output is generated if there are no messages. Inpygettextoutput is still generate even if no messages are found, the header is still sent.
We should fix it to work likexgettextand not produce "empty" output.

Commenting here as well. I think the input file should be required, I think that one is clear.
As for not producing any output if there are no messages, I'm not so sure. There's nothing wrong with an empty po file and it might just be the case that your sources happen to have no gettext calls that can be extracted. So I lean more towards keeping this behaviour.

@picnixz Unrelated to this issue, but I've seen you throw the
triagedlabel on a few things. What criteria should we follow for adding that label?StanFromIreland commentedon Apr 27, 2025
I’ve asked that before ;-)
He does it for tools as there is no label for them.
ZeroIntensity commentedon Apr 27, 2025
Ah. I assume he's been shot down on a
topic-toolslabel before?StanFromIreland commentedon Apr 27, 2025
Yes, he tried in core-workflow but his issue was closed as a duplicate of a closed issue where no conclusion was reached. :-(

It's a shame GH only shows the labels and not projects on the issues page :/

I use "triaged" whenever I want to indicate to myself "hey don't look at this issue again, you've already checked it..."

I'd like to fix only the first case: no input files given.
Plan:
pygettext: no input file given/Try 'pygettext --help' for more information.to stderr and exit 1, likexgettext.test_header,test_POT_Creation_Date,test_output_option), add a test for the new error, and add a NEWS entry.I'd leave the second case (no output when no messages are found) out, since @tomasr8 leaned toward keeping the empty .pot.
