The latest release of Notepad++, a Windows OS based open source text editor, supports Tcl syntax highlighting. It can be downloaded at the following web address:
http://sourceforge.net/projects/notepad-plus
JMN 2005-11-29 This seems like a fairly nice usable editor.. but the Tcl syntax highlighting is not quite there yet.
Some issues I've noticed:
problem 1) If a tcl comment line contains 'if' as the first element - notepad++ incorrectly starts a new nesting level - putting other sections out of sync.
e.g the following line is mishandled.
# if blah blah blah
problem 2) Escaped brackets aren't matched properly.
e.g the following sorts of lines are mishandled (incorrect bracket-match highlighting)
set x {abc\{d}
set y [list a b\[c d]
set z [list a {b[c} d]
