    I'd rather write programs to write programs than write programs.

    Make sure you're running node 12 or greater. The test suite will fail on older versions of node.

    If you add a new generator, make sure to update the list of supported languages in cli.js or else it won't be accessible from the command line. Further, you'll want to update test.js and index.js for your new generator to make it part of the testing.

    If you want to add new functionality, start with a test.

    • Create a file containing the curl command in fixtures/curl_commands with a descriptive filename like post_with_headers.txt
    • Create a file containing the output in fixtures/python_output/ with a matching filename (but different extension) like
    • Run tests with npm test.
    • If your filenames match correctly, you should see one failing test. Fix it by modifying the parser in util.js or the generators in generators/

    The parser generates a generic data structure consumed by code generator functions.

    You can run a specific test with this command:

    node test.js --test=test_name

    where "test_name" is a file (without extension) in fixtures/curl_commands

    You can run a specific test with this command:

    node test.js --language=R

    I recommend setting this up with a debugger so you can see exactly what the parser is passing to the generator. Here's my Intellij run configuration for a single test: Screenshot of intellij debug configuration

    Before submitting a PR, please check that your JS code conforms to the code style enforced by standardjs. Use the following to fix your code if it doesn't:

    $ standard --fix my_file.js

    If you get stuck, please reach out via email. I am always willing to hop on a google hangout and pair program.
