What is Lime?

I love the Sublime Text editor. I have created several plugins to make it even better. One thing that scares me though is that it is not open sourced and the pace of nightly releases have recently been anything but nightly, even now that version 3 is out in Beta.

There was a period of about 6 months after the Sublime Text 2 “stable“ version was released where pretty much nothing at all was communicated to the users about what to expect in the future, nor was there much support offered in the forums. People including myself were wondering if the product was dead and I personally wondered what would happen to all the bugs, crashes and annoyances that still existed in ST2. This lack of communication is a dealbreaker to me and I decided that I will not spend any more money on that product because of it.

As none of the other text editors I've tried come close to the love I had for Sublime Text, I decided I had to create my own.

The frontend(s) are not ready to replace your favourite editor, but the backend itself I believe isn't too far away.

Goals

  • ☑ 100% Open source
  • ☑ Compatible with Textmate color schemes (which is what ST is using)
  • ☑ Compatible with Textmate syntax definitions (which again is what ST is using)
  • ☐ Compatible with Textmate snippets
  • ☐ Compatible with Sublime Text’s python plugin API. I’ll probably never implement this 100%, only the api bits I need for the plugins I use.
  • ☐ Compatible with Sublime Text’s keybindings and settings
  • ☐ Compatible with Sublime Text snippets
  • ☐ Sublime Text’s Goto anything panel
  • ☑ Multiple cursors
  • ☑ Regression tests (Programming in Go makes it trivial and even fun to write them ;))
  • ☐ Support for plugging in a custom parser for more advanced syntax highlighting.
  • ☐ Terminal UI (Maybe I’ll work on a simple non-terminal UI at some point)
  • ☐ Cross platform (It appears to be compiling and running on OSX and Linux last I tried, but needs further validation.)

Why can’t I open up an issue?

Because I’m just a single person and I don’t want to offer up my spare time doing support or dealing with feature requests that I don’t care about myself. If you want a feature implemented or a bug fixed, fork it and implement it yourself and submit a pull request when you’re happy with the implementation.
