The test tool divvun-runtime

The tool itself is documented at [divvun.github.io/divvun-runtime](https://divvun.github.io/divvun-runtime]. This document shows how linguists should use it for grammar checker testing. It comes in two versions, we look at them one at a time, after having given some practical advice on how to get it.

How to get divvun-runtime

• Go to the divvun-runtime page on git
• Look for the column to the right on that page, the second section is called Releases. Click on Latest. For mac, download the two first ones (-apple-), open them, put the -playground- one in your /Application folder and the other one (divvun-runtime) in some folder in your path (echo $PATH | tr ":" "\n" if you don’t know). For linux (and linux on Windows), download the third file.
• If you rather want to build it yourself (advice: Leave this to the developers)

The two versions of divvun-runtime

1. The graphical version Divvun Runtime Playground

• Make sure you have compiled the grammarchecker, and have a file bundle.drb in the tools/grammarchecker catalogue
• Open Divvun Runtime Playground
• Click on Open Bundle in the upper right corner
• Choose the bundle.drb file and open it
• Add a sentence in the lower left corner and press Run to see the correction and feedback. Each step of the analysis process may be expanded and inspected.
• To check whether the error messages are working, click the Fluent tester tab. If there are now red warnings, everything is ok

2. The command line program divvun-runtime

The program may be treated as any command line program:

which divvun-runtime
divvun-runtime -V
divvun-runtime -h
man divvun-runtime sync --help
... etc

You may use divvun-runtime in a pipeline standing in grammarchecker (example from lang-nob):

echo "Vi prøver og kjøre." | divvun-runtime run

It may also be used interactively:

divvun-runtime
Vi prøver og kjøre.

This latter option will give all 13 steps in the grammarchecker process.
