Allow to build subset of languages from console

When I want to build just one language or a subset, I usually just locally edit the languages.txt file. Since it's in a Git repository, after I'm done it's easy enough to just do a git checkout languages.txt.

But this seems like a good idea too. Does it work? :) I will test it later and commit it. Thanks!

There are 2 other mk(something) scripts that should also be updated in the same way.

Hm. The commit you made seems to have added a mkall.sh script but I don't see changes to the other scripts.

Oh I see, the other two commits didn't reference this issue. That's OK.

Thanks!

This is super useful. Thanks @guiu.rocafort.ferrer.

The mkzips.sh command no longer works for me. When running it with no args, I get:

+ '[[]' 0 -lt 1 ']]'
./mkzips.sh: line 10: [[]: command not found
+ mkdir -p ../ebooks/zips
./mkzips.sh: line 18: $1: unbound variable

I just edited my local copy to revert the commit... but it needs attention.

One note: you are not supposed to run that command with no args -- it requires the version number, but it still shouldn't crash. I didn't try it with the correct args.

Well, probably the old script didn't behave well either. Ideally, I think it would give you a message like "You need to provide the version number". The author of the old script (me) didn't bother with nice things like that. ;}

So... we could probably just leave it. I did verify that if you provide the version number, the script works fine.

One other minor problem to fix: There are spaces at the ends of some lines. Please remove them -- we don't like end-of-line whitespace in the Drupal project. You can usually set your code editor to remove or highlight end-of-line spaces. Thanks!

For reference, here is the other commit that was made for this issue (not automatically linked here):
https://git.drupalcode.org/project/user_guide/commit/01d50888835eefc7d6c...

So before the change, if you ran mkzips.sh without specifying the version string, you would get:

+ mkdir -p ../ebooks/zips
./mkzips.sh: line 12: $1: unbound variable

This is not a beautiful error message, but it seems a bit clearer than #9.

It looks like the new script is trying to detect that the argument is missing, but it just isn't working (at least for me):

if [[] $# -lt 1 ]]; then
  echo "You must specify at least one parameter indicating the version"
  echo "Usage: ./mkzips.sh version [ lang1 lang2 lang3 ]"
  exit -1
fi

Looks good, thanks for the quick action!
