Scheme Programming Language :: Tabs in Chicken


	Tabs in Chicken Can anyone tell me why (char=? ch #\tab) is giving me an unexpected list terminator error in Chicken? Thanks Bill "WoodHacker" wrote: > Can anyone tell me why > (char=? ch #\tab) > is giving me an unexpected list terminator error in Chicken? I cannot reproduce this error. I have tried versions 2.5 and 2.603, linux-unix-gnu-x86, without any problems.

The previous condition is (char=? ch #\space), which works. In fact, if I take that one condition out it all works. I'm running it on an AMD/64 system. Latest version of Chicken - 2.6, linux-unix-gnu-x86-64. Makes no sense. WoodHacker <ramsa@comcast.net> wrote: > The line is part of a cond clause.

It looks like we need a minimal but complete example which triggers the error you reported. Dnia 28-03-2007, sro o godzinie 12:34 -0700, WoodHacker napisal(a): > The line is part of a cond clause. I guess the cond clause has mismatched parentheses. -- __("< Marcin Kowalczyk \__/ qrc@knm.org.pl ^^ http://qrnik.knm.org.pl/~qrczak/ On Mar 28, 4:25 pm, Sven.Hartru@FernUni-Hagen.de wrote: > "WoodHacker" wrote: > > The line is part of a cond clause.

I started to write up this reply by copying out the procedure the line is in. I then ran it again to get the exact error. The only problem is that now it does not give me the error!!!! So help me, I made no changes. Could something on my system have gone out of whack causing the problem - which a good night sleep fixed? I sometimes wonder why I do this. The code is: (define parse-start (lambda (f) (let ((ch (read-char f)) (text "")) (cond ((eof-object? ch) #f) ((= (get-token ch) LETTER) (add-and-continue ch LETTER f text)) ((= (get-token ch) NUMBER) (add-and-continue ch NUMBER f text)) ((char=? ch #\space) (parse-start f)) ((char=? ch #\tab) (parse-start f)))))) Thanks for putting up with me.
