I like a bit of TiVo hacking in spare time - TiVo uses a Linux variant and TCL. I'd like to write TCL scripts on my Windows laptop, test them and then FTP them over to my TiVo. Can I have a recommendation for a TCL debugging environment for Windows, please? ...
I have written code to read a windows bitmap and would now like to display it with ltk. How can I construct an appropriate object? Is there such functionality in ltk? If not how can I do it directly interfacing to tk? ...
I've been forced to code in Tcl a number of times, and just can't wrap my head around this language. It's not just that it is syntactically different than c-like languages: Lisp is different but genius, prolog is different with a valid cause. Tcl is different because it was a bad idea taken to its fullest possible extension. "Lets mak...
I'm trying to get an expect script to work, and when I use the -re flag (to invoke regular expression parsing), the 'timeout' keyword seems to no longer work. When the following script is run, I get the message 'timed out at step 1', then 'starting step 2' and then it times out but does NOT print the 'timed out at step 2' I just get a ne...
Tcl/Tk is a simple way to script small GUIs. Can anyone give a nice example with a button and a text widget. When the button is pressed should a shell command be executed and the output piped to the text widget. If you have other nice and clean examples for useful tasks, please add them too. ...

I've been working on a project of porting an old solaris CL program to run on Linux, and barring some unrelated hardware issues, that's finished. Now I want a GUI for it, so the user can choose among the various options with drop downs and check boxes, as well as some text input areas for options that aren't so restricted, like the filen...
Pursuant to the advice given in this question I have written a little gui to take the options for a command line C program and pass them on to said C program which is already set up to process them. It displays just like I wanted. However, I would like to verify that the values stored in the variables are correct. Getting the values to...
Hi, I have a tcl script which 'exec' rpmbuild. When doing so, the 'topdir' used by rpmbuild is wrong. I have a .rpmmacros file in my home directory and if I call manually rpmbuild, it works fine, ie. the 'topdir' is not the default one. I added a [exec rpmbuild "--showrc" ] in the tcl script to check the value of topdir and it says '-...
Hi. I have a main TCL proc that sources tons of other tcl procs in other folders and subsequent subdirectories.

I'm learning to write a TCL (expect) scripts and I notice that some examples show to use spawn, while others show the command exec. I tried googling, but can't find what is the difference? Suppose I call 'exec' in a middle of a long expect script, what can I expect to happen? ...
I'm learning tcl (expect) and now I came to an interesting issue. I need a command to move/rename a bunch of files with extension .status. I tried these: spawn /bin/mv *.status some_dir exec /bin/mv *.status some_dir Of course, that did not work. I googled a bit and found something about glob, but it doesn't seem to work the way I wan...
