Series submodule add: partial conversion to C | expand

Commit Message

Atharva Raykar July 8, 2021, 9:55 a.m. UTC
The standard `die()` function that is used in C code prefixes all the
messages passed to it with 'fatal: '. This does not happen with the
`die` used in 'git-submodule.sh'.

Let's prefix each of the shell die messages with 'fatal: ' so that when
they are converted to C code, the error messages stay the same as before
the conversion.

Note that the shell version of `die` exits with error code 1, while the
C version exits with error code 128. In practice, this does not change
any behaviour, as no functionality in 'submodule add' and 'submodule
update' relies on the value of the exit code.

Sounds good.  More importantly, the error messages from the
resulting system would become more uniform---after all, the end
users would not care if scripted part of the system is emitting the
error messages, or the message comes from a built-in version.

That sounds good.

Except that, "fatal: " isn't subjected to translation. And this will
create new translatable item for translator. Perhaps:

-		 die "$(eval_gettext "please make sure that the .gitmodules file is in the working tree")"
+		 die "fatal: $(eval_gettext "please make sure that the .gitmodules file is in the working tree")"

Okay, I have made the change. I was wondering if there any specific
reason as to why 'fatal' should not be translated? Is it because
an intermediate change like this should not create more work for
translators?

Yes. That's likely the intention.
