Notepad++ does not support [Incr Tcl]: it does not apply syntax highlighting to *.itcl files.
We can tell Notepad++ to treat *.itcl file as Tcl. This is not a perfect solution, but it is very quick to implement. Here are the steps:
- Edit the file langs.xml from the Notepad++ dir
- Search for ext=”tcl” and replace with ext=”tcl itcl”
That’s all! You can now enjoy syntax highlighting when editing you .itcl file. I am sure there are more throughout solutions, but this one is quick and easy–give it a try.
