I am trying to set up an autocomplete feature for Codemirror for the Python language. Unfortunately, it seems that Codemirror only includes the files necessary for Javascript key term completion.

Has anyone built Python hint file for CodeMirror similar to the JavaScript Version?

(Edit for future reference: link to similar question on CodeMirror Google Group)

I start the python autocomplete with a js based on pig-hint from codemirror 3.

You can get the python-hint.js from here.

to work, you need in your html:

  1. include simple-hint,js and python-hint.js, simple-hint.css plus codemirror.js

  2. add this script:

    <script>
    CodeMirror.commands.autocomplete = function(cm) {
         CodeMirror.simpleHint(cm, CodeMirror.pythonHint);
       }
    </script>
    

python-hint.js is a basic js I have created today and not reviewed in depth.

Home; Manual; Code. Autocomplete. Autocomplete Demo Press ctrl-space to activate autocompletion. Built on top of the show-hint and javascript-hint

I'm the original author of the Python parser for Codemirror (1 and 2). You are correct that the Python parser does not offer enough information for autocomplete. I tried to build it into the parser when Codemirror 2 came around but it proved too difficult for my JS skills at the time.

I have far more skills now but far less time. Perhaps someday I'll get back to it. Or if someone wants to take it up, I would be glad to help.
