I use Jedit with hoc highlighting. Here is the information:
Hoc editing: jEdit Editor with Neuron highlighting
1. download jEdit (
http://www.jedit.org/index.php?page=download)
2. download neuron.xml for jEdit (
http://community.jedit.org/?q=filestore ... 1&from=60P)
3. copy neuron.xml into jEdit directory C:\Program Files\jEdit\modes and add the file information to the catalog file (named catalog with no extension) in the same directory
<MODE NAME="neuron" FILE="neuron.xml"
FILE_NAME_GLOB="*.hoc" />
4. In jEdit, go to Utilities, Options, Editing and verify it contains the mode to neuron
5. When you open a hoc file it will be highlighted/colored for syntax
