Compare those. the 'do body is done before the 'increment' operations.

Ok, i have been using lisp for a while, and have already 'embraced the parentheses'. I like the high level of whitespace in well indented with the syntax attractive. And if used well, it is very clear. And if done badly it will look bad, just like parentheses alone. Imo the only point of the code is...

@qbg: I agree with you there. But in a way, the changed code can look cleaner, although it is less clean for having more syntax. It saves n+1 characters for a list with only lists as elements. The adding of syntax, and decreasing sight of the tree are the issues here afaik. I think it can make the c...

Why not just (defmethod draw-object ((object its-type) (layer fixnum) (env environment)...) Then you can make passes for each layer and objects can write to layers as they wish. You might of course also optimize to avoid some of the layers objects that do not draw to many layers, using an array for ...

You need to look better. Or count the hooks, 's and 'b 's. Note that s <-> ; and b <-> | its just that ; and | dont make good symbols. (Well, |;|) Or look at the code i changed with it. The lack of many hooks.

It could be possible to save a character per sublist: use a symbol as separator. I will use a seperator ';' and '|' as a blocker of separated sublisting. (Although they wouldnt work for common lisp since they are already used.) If you read in the blocker and separator as symbols, you can make them w...

I don't like any of them very well, but the one with the dollar signs the best. See no particular reason to use $1 ,etc and not $any-symbol. I admit have not giving it that much thought. About needing to move dollar signs, if it is longer code, the (lambda(blabla) body) would be small relative to th...

I use cl-sdl and cl-opengl together, that works, on ubuntu at least. That doesn't give you anything to make UI widgets with, though. GLUTs keyboard and mouse input is just plain limited, afaik. I remember using it in c(++?) and just hitting walls, but forgot what the limitations were. I wouldn't use...

Are you sure they don't mean the string "yyyymmdd" then you can use subseq . (defun year(str) (read-from-string(subseq str 0 4))) (defun month(str) (read-from-string(subseq str 4 6))) (defun day(str)(read-from-string(subseq str 6 8))) Of course, it assumes the string is long enough. Hmm, i...
