Vi mode: Vi mode for Drscheme

by Jon Rafkind (rafkind at cs dot utah dot edu)

This package provides a mode for Drscheme that emulates some Vi commands. This package is very alpha, it doesn’t have a lot of features and probably has some bugs. Feedback and bug reports is more than welcome!

1 Install

Execute the following line in Drscheme or Mzscheme "(require (planet \"tool.ss\" (\"kazzmir\" \"vi.plt\")))"

Then restart Drscheme.

2 Uninstall

On the command line

$ planet show

kazzmir       vi.plt  1 0

$ planet remove kazzmir vi.plt 1 0

Or if you wish to keep vi.plt around edit tool.ss and search for "(define tool" "\n" "  " "...)"

Then comment out the line that extends the Drscheme definitions text. "(drscheme:get/extend:extend-definitions-text definition-text)"
