$ npm install --save curlconverter


var curlconverter = require('curlconverter');

curlconverter.toPython("curl '' -H 'Accept-Encoding: gzip, deflate, sdch' -H 'Accept-Language: en-US,en;q=0.8' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H 'Referer:' -H 'Cookie: GeoIP=US:Albuquerque:35.1241:-106.7675:v4; uls-previous-languages=%5B%22en%22%5D; mediaWiki.user.sessionId=VaHaeVW3m0ymvx9kacwshZIDkv8zgF9y; centralnotice_buckets_by_campaign=%7B%22C14_enUS_dsk_lw_FR%22%3A%7B%22val%22%3A%220%22%2C%22start%22%3A1412172000%2C%22end%22%3A1422576000%7D%2C%22C14_en5C_dec_dsk_FR%22%3A%7B%22val%22%3A3%2C%22start%22%3A1417514400%2C%22end%22%3A1425290400%7D%2C%22C14_en5C_bkup_dsk_FR%22%3A%7B%22val%22%3A1%2C%22start%22%3A1417428000%2C%22end%22%3A1425290400%7D%7D; centralnotice_bannercount_fr12=22; centralnotice_bannercount_fr12-wait=14' -H 'Connection: keep-alive' --compressed");

Returns a string of Python code like:

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

Make sure you're running node 6 or greater. The test suite will fail on older versions of node.

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

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

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