Kate is a powerful text editor. I used it in the past, but unfortunately it doesn't have smalltalk syntax highlighting and I'm a big fan of Vim.

Yesterday I gave Kate another try, and I discovered that it has a VI mode in KDE4! It was enough for me to hack it a bit :)

First I wanted to force Kate to produce the right indentation, like I did for Vim, so I added a custom filetype for smalltalk files, and added the following variables:

kate: indent-width 4; mixedindent on; tab-width 8; 

The next step was to add syntax highlighting for Smalltalk files. Writing syntax files for Kate is actually very easy, and very well explained.
