Set up the Development Environment

Open a dev shell:

git clone git@github.com:b4er/recalc.git
cd recalc/
nix develop

Running Tests

This will drop you into a shell with all necessary dependencies available where you can run the test suite:

cabal test
npm --prefix recalc-vscode run tests

Running the Web Extension in Development

In a dev shell open the current directory (eg. codium .), launch the extension development host using (F5).

Logging

When running the extension open the Output view and select the recalc channel. You should see the logs there (you can set the Log Level in the Extension Settings).

The Haskell backend uses stdout for JSON-RPC, but all output written to stderr will be forwarded to the Output channel mentioned earlier.

When running the NPM tests manually, you can set the environment variable LOG_OUTPUT=true and it will write logs during the tests to a logfile.
