@v217 thanks for the input, I'll push a new version with the current code. There's currently a lot of incoming traffic from Hacker News (Github stars have almost doubled in the last 6 hours) so I'm going to wait a day or so to avoid the risk of accidentally pushing a breaking change.

A cli UI would also make a pipx installation meaningful - the easiest, most user friendly way to manage python packages.

@PJ-Finlay Great Thanks!

We're live! I realized Snapcraft was a little more involved so I'm waiting on it for now but live on PyPI.

Works great with pipx! Thanks!

It would be really good to add input from a file BTW as proposed by OP:

argos-translate-cli -file Novel.txt -from en -to de

Pasting long text on the CLI is too error prone as mentioned at: https://askubuntu.com/questions/380847/is-it-possible-to-translate-words-via-terminal/1309774#1309774

Thanks for the issue, this is something I've been meaning to add for a while and I just pushed a basic cli.

Usage:
$ argos-translate-cli --from-lang en --to-lang es "Hello World"
Hola Mundo

I'm going to wait a bit before before pushing this to PyPI or the Snap Store so for now if you want to use it you'll need to install from source. Before pushing there should also be the ability to read text from standard input and install packages.

Any feedback on the API before it's too set in stone is also appreciated.

@v217 I agree the plan is to push this to PyPI. I already added the CLI executable as a script in setup.py so pushing to PyPI wouldn't require a code change. I've just been waiting until the CLI was more complete and stable but if someone needs the CLI from PyPI I could push it sooner. You can also install the bleeding edge version from the Github repo with pip in one line:

pip3 install git+https://github.com/argosopentech/argos-translate

Maybe the documentation should be updates to show this instead of the more verbose example that is currently there. However, if someones new to the command line has the one command version fail they may have an easier time debugging the existing version.

@PJ-Finlay Great! For me only the funcionality in the example would be very useful and I don't mind if the cli interface changes. I think, people who use argos-translate in their scripts use the library, and for interactive use cli interface changes don't matter.

how to resolve this

from argos-translate.

Do you have the English and Spanish models installed? We should probably add a more helpful error message for when this happens.
