Setting up Pairviewer locally

Clone the git repository

Run git clone https://github.com/apertium/pairviewer.git

Set up local server with Python

Open on browser

Now all that's left to do is try out Pairviewer yourself! Open your localhost address (can be copy-pasted from the terminal output of previous step) on a browser. And now you're all set!

Using Pairviewer

How Pairviewer works

Known bugs

There are a few apparent bugs that should be fixed before the pair viewer goes public.

• in initial view (sometimes?), quz has no line connecting it to spa
• sometimes two- and three-letter codes don't seem to merge
  • when just trunk and staging are selected, tur/tr and nob/nb are each separate from one another
  • when trunk, staging, and nursery are selected, nob/nb are merged, but tur/tr are separate
• when all possible pairs are viewed (including ones with missing stems, etc.), pa doesn't have a line connecting it to ur
