I like emacs tcl-eval-region/defun very much, but sometimes if I walk through my code, I get annoying output for some commands. This makes tcl-eval-region somehow ineffective.
set temp {0 0 0 0 0 0 0 0 0 0}
=> 0 0 0 0 0 0 0 0 0 0This 2 elisp-functions do eval code of your source code the way tcl-eval-region does, but they prevent output by replacing ;;; with code without results before evaluating. I chose ;;; because one can use it without code becoming too dirty.
set temp {1 1 1 1 1 1 1 1 1 1};;; #output is canceled
=>
set temp test; #output is not affected
=> test
puts a;;; #output is not affected
=> a
how-to-use the functions: copy & paste the code into a file with .el extension. M-x load-file that file and then use them as you would use tcl-eval-region. after you have invoked them in a source buffer once, you have key-bindings C-c C-r for tcl-eval-region-no-output and C-c C-l for tcl-eval-line-no-output.
draw-back of this method: take care that you do not use ;;; for another purpose in the code you are evaluating via this functions.

)Bryan Oakley 16 Sept 2008 - Following is an elisp macro that takes a line of tcl code that looks like:
foo -option1 value1 -option2 {option 2} -option3 \
[value three -foo -bar]... and converts it to something that looks like:
foo \
-option1 value1 \
-option2 {option 2} \
-option3 [value three -foo -bar]I've wanted this function for years and never got around to writing it. I was experimenting with stackoverflow.com and when I didn't get a suitable answer for my question I suddenly found the motivation to write it myself. My elisp is extremely rusty so I make no guarantees but it seems to work in the limited amount of testing I've done.
Bind tcl-multiline-options to something like C-x \, move your cursor onto a line of Tcl code (or even a continuation line), press the magic keystroke, and voila!
