wlc 0.3, a command line utility for Weblate, has been just released. This is probably first release which is worth using so it's probably also worth of bigger announcement.
It is built on API introduced in Weblate 2.6 and still being in development. Several commands from wlc will not work properly if executed against Weblate 2.6, first fully supported version will be 2.7 (current git is okay as well, it is now running on both demo and hosting servers).
How to use it? First you will probably want to store the credentials, so that your requests are authenticated (you can do unauthenticated requests as well, but obviously only read only and on public objects), so lets create
url = https://hosted.weblate.org/api/
https://hosted.weblate.org/api/ = APIKEY
Now you can do basic commands:
$ wlc show weblate/master/cs
