Arithmetics Example

Interpreter CLI

The Arithmetics Example features an interpreter that you can run via cli.

• Ensure the complete project was properly built, otherwise run npm install from the root of the Langium project.
• Use node ./bin/cli from the arithmetics directory to run the cli. Follow the instructions or use node ./bin/cli eval <full-path-to-calc-file>.

The interpreter calculates each Evaluation in the source file and prints the result.

You also can use arithmetics-cli as a replacement for node ./bin/cli, if you install the cli globally.

• Run npm install -g ./ from the arithmetics directory.
• Use arithmetics-cli or arithmetics-cli eval <full-path-to-calc-file>.
