Tried to test, but have a permission problem:

vagrant@debian-7:/vagrant/cli$ php tracker.php make langtemplates

ERROR: Unable to write language storage file to /tmp/g11n/CLI/cli/en-GB.cli.php

Hmm, I am a little lost since I can not reproduce this error :(
Could you manually set the permission for the /tmp directory to 0777 if they are set to anything else and re-try ?

Strange... Why I have it? :)

Without root access (I do not know the password is) I can't.

vagrant@debian-7:/$ chmod +x /tmp
chmod: changing permissions of `/tmp': Operation not permitted

Try sudo ;)

sudo chmod 0777 /tmp

Hmm, you should encounter the same problem if you access the "front end" of the Vagrant box with http://127.0.0.1:2345/

Could you verify that cache files are written to /tmp inside the box?

Another hmm.... OK I found out that you can not use the same cache dir for web and CLI...

Instead of the chmod you can simply wipe the cache dir before running the CLI script (using sudo) like
sudo rm -rf /tmp/g11n

Not sure how to fix this properly :(

OK last Hmm...
I think I fixed this in elkuku/g11n@4bd0d91 - next dependency update should bring this in ;)

Sorry for the confusion :(

sudo rm -rf /tmp/g11n did the job and I've manged to create templates. But where the language files are stored? make langfiles command is working, but I can't find the files :)

And yes I get permission denied error now. Can you add deps update to solve it?

You are right, that part was missing...
Since we use Transifex now to "create" the language files, the template file has to be uploaded first.
I have however updated the make langfiles command to create the language files. I have also updated the update transifex and get transifex commands - but I have not tested them ;)

I've also updated the composer.json file.

Good. Now how to change the language? I see this in the code:
$lang = $this->input->get('lang');
But do not understand how to pass it :)

One more bug I found. Running get help throws an error:

Like this:

Sorry, but I really like our colors :)

One more bug I found. Running get help throws an error:

Has been fixed

All is good!

@mbabker a note for you - update deps after deployment, because composer.json was updated

I just tested the 'get transifex' and 'update transifex' commands, and they seem to work OK

Interesting that on Windows (not a Vagrant box) I have a problem with the characters encoding

Interesting but not surprising
