Is that why even relative paths (“./colorselect”) don’t work? I’d have thought it would at least know its working directory.
I made some changes to colorselect. There’s now command line parsing allowing you to pass in a base color and suppress output in case, uh, you just want to look up a color. The “Apply” button (or “OK” if --quiet is on) is now the default button. Some very minor refactoring was also done because I’m anal retentive. Now I just need some way of reading in and saving colorsets from my config…

though it is dirt simple and not even totally done. I wanted to be able to pass in a hex value as a starting color so you could cancel out, but I’ve only just laid some preliminary code for that as of yet (the rest would probably double the code size), and now I wonder if it wouldn’t be possible to have dynamic updates. But I’ll glady release what I have, it’s small enough just to include in a post. I’ve stripped out the unnecessary parts for clarity’s sake, but left in some comments in case anyone else is new to GTK (this is my first GUI app since my VisualBasic days years and years ago 
).
