Hello!
I am trying to write the code for internationalization. The functions I use
are the ones from C's parser flow (dgettext, setlocale, etc).
I never worked with gettext (as a bash command) before, and I have some
trouble understanding how I automatically generate the .mo files and put
them into /usr/local/share/locale (where the code from the
examples/c/bisthromatic hints they should be found). My understanding is
that from the .po files I have to generate .mo files, and these are used by
the programs generated with Bison.
If I try to run "sudo make install" in the po directory I get this error:
[...]
/usr/bin/install: cannot stat './bg.gmo': No such file or directory
installing ./bg.gmo as /usr/local/share/locale/bg/LC_MESSAGES/bison.mo
[...]
and so on for each language file. After the command, no files exist in the
LC_MESSAGES directories.
If I run make update-po or update-gmo, I also get errors for missing files.
If I create a .mo file by hand, using msgfmt, and then move it
into /usr/local/share/locale/<language>/LC_MESSAGES/, the output gets
translated as expected.
The second problem is that I expected dgettext to receive the argument
"bison-runtime", like in C, not "bison", as it happens now in D. If I use
"bison-runtime" the messages remain in English.
Here [1] (and also as attachments) is a work in progress for this task,
with the mention that examples/d/c/calc/calc.y is modified just for testing
reasons, it will not be changed in the official commit.
Example of output with LANG=ro_RO.UTF-8:
~/bison/examples/d/calc$ ./calc
