This extension provides helper tools for working with JavaScript and Python inside of Komodo. If you want to play around with the JavaScript API, do some simple python coding tests, probe the Komodo API for an extension, or play with the internals of Komodo, then this is for you!

Brief guide:

  • Once installed, access it through the Tools->Extension Developer menu
  • When working with the JavaScript tools, you'll generally want to set the Scope to be the main Komodo window first, otherwise the Komodo API won't be available to you.
  • Use Tab for completions on objects and scope, fantastic!

Note: This extension is based upon Ted Mielczarek's \"Extension Developer's Extension\". The only differences between this version and Ted's is:

  • Updated to include a Komodo overlay
  • Includes the Python Shell, this requires PyXPCOM (already provided by Komodo).
