Requirements:

$ pip install -r requirements.txt

Configuration:

API requires two configuration files for execution:

config.json contains a list of domains with their names and a corresponding list of translation engines that share the same set of supported factors like output style and language. Each of these workers has its name and two settings: IP address and port.

dev.ini specifies a mapping from the authentification key to the domain in which translation is expected. In the example, the second line says that users with authentification key public will be directed to the general domain.

Examples of config.json and dev.ini are provided in this repository.

Running from command line:

Unix Bash
$ export FLASK_APP=sauron
$ flask run

Windows CMD
> set FLASK_APP=sauron
> flask run

Deploying:

One way to deploy is gunicorn and GNU screen session. To support start, stop and restart commands one can add these lines to the .bash_aliases:

alias sauron-start='cd project/directory && screen -S sauron sudo gunicorn [OPTIONS] && cd ~'
alias sauron-stop='ps aux |grep gunicorn |grep sauron | awk '"'"'{ print $2 }'"'"' | sudo xargs kill -s QUIT'
alias sauron-restart='sauron-stop && sauron-start'
