Re: Hello! (Just seemed like the right place to say it.)

Hello! Thanks for being a welcoming group! I look forward to being an active participant! Welcome! lately I've been working through LeetCode problems and similar, as a way to sharpen my mind a bit outside of my work life (which is mostly not that interesting from a code standpoint); is the "Homewor...

[ANN] Some R7RS Scheme Libraries

Hi list, Recently I have been writing and repackaging a variety of Scheme libraries to work on R7RS implementations. The collection is a work in progress, but is currently tested on Chibi, Kawa and Larceny: with some exceptions, the included examples and tests work on all three implementations. For ...

Re: executing a random command

I don't know Emacs lisp so this may be off base, but: (setq nameOfRandomColorTheme (nth randomNumber '( "color-theme-xemacs" "color-theme-xp"))) is setting nameOfRandomColorTheme to a string value, and then: (nameOfRandomColorTheme) is using that string as if it were a function. In your example you ...

Re: Gimp's scheme code to extract text from layers

I don't know Gimp, but your bracketing is off. (let* ((ff (cadr (file-glob "*.xcf" 1)))) (filename "") (image 1) (layer 0)) For example, write the start like this: (let* ((ff (cadr (file-glob "*.xcf" 1)))) <-- you have one too many close brackets here, they should only close up to the one before 'ff...

Re: Loop 2D-Array

You are close. How does 'loop' return a value?

> (loop for x from 1 to 3 do x)
> (loop for x from 1 to 3 collect x)
(list 1 2 3)

Then look again at your two loops ... if you change one word you will get some results back, which will still need some tidying up.

Just joined

I just found this list, and joined as I've recently started again with Scheme. I've been using Lisp and Scheme for quite some time, in teaching and for my own projects. I've always enjoyed the simplicity of Scheme. Lisp feels "gritty" to me, but also very practical. For various reasons, I've had a f...
