I've just forwarded this onto a co-worker wwho has been conducting a little homework on this. And he in fact ordered me breakfast due tto the fact that I stumbled upon it ffor him... lol. So let me reword this.... Thanks for the meal!! But yeah, thanx for spending the time to discuss this topic here on your internet site. read-time string concatenation - Tomas Zellerin urn:md5:37e9f738c080399128fba19fb1d28270 2011-07-13T16:26:59+02:00 2011-07-13T16:26:59+02:00 Tomas Zellerin I do slime-compile-and-load-file (C-c C-k). It finds some compiler notes and tries to scroll to them, and breaks on it. Error is The value of STRING is NIL, which is not a string Relevant stack trace: (SWANK-BACKEND::SKIP-TOPLEVEL-FORMS 6 #<SB-SYS:FD-STREAM for XXX>) (SWANK-BACKEND::SOURCE-PATH-FILE-POSITION (5) XXX) (SWANK-BACKEND::LOCATE-COMPILER-NOTE ..) and skip-toplevel-forms is defined (for sbcl at least) as (defun skip-toplevel-forms (n stream) (let ((*read-suppress* t)) (dotimes (i n) (read stream)))) Sorry for poor formatting, I hope it makes sense. I suppose you would hit the problem when you comment something out with #+nil as well. read-time string concatenation - Didier urn:md5:ee805720a86395f78ce1af70385cc51a 2011-07-13T11:18:52+02:00 2011-07-13T11:18:52+02:00 Didier @Tomas Can you provide a specific scenario which exhibits the problem? I understand what you say but I've never encountered the problem in any SBCL+Slime session. Thank you. read-time string concatenation - Tomas Zellerin urn:md5:864023893f30fdfd8476b2684d29c5be 2011-07-13T08:40:10+02:00 2011-07-13T08:40:10+02:00 Tomas Zellerin Hi, I like the idea, however - it does not work smoothly e.g. in Slime and sbcl. I get problems because (shortly) it uses reading with *read-supress* to get to place in a file, and thus your check-type fails. So one should probably handle the *read-suppress* situation specifically. (Other fix I did for myself was to insert space or newline between strings, using ~" vs ~@", but this is more of a taste question) read-time string concatenation - Didier urn:md5:27592ad5d3e84859383a431b58050878 2011-06-27T10:16:12+02:00 2011-06-27T10:16:12+02:00 Didier @mon-key Your request seem to be about formatting the DISPLAY of documentation material, whereas here I was concerned about formatting the CODE itself. So I fail to see the relation between the two... read-time string concatenation - mon-key urn:md5:b708a7dc463054d78cd3303a8f87d2f7 2011-06-26T19:02:48+02:00 2011-06-26T19:02:48+02:00 mon-key Thanks for your ongoing attention to all things string/format/documentation related and for taking the time to bring your findings to the interwebs. One thing i find lacking whether for your ~ reader (and prob. Xach's `||' function as well) is the ability to specify a "fill column". It would be nice to have a lambda list like this: (stream char &optional (default-fill *read-tilde-refill*)) where *read-tilde-refill* defaults to 80 and has the type signature: (or null (integer 1 *)) and where DEFAULT-FILL parameter could take one of the forms: NIL -- no fill T -- fill to *read-tilde-refill* columns) <INT> -- fill to <INT> columns. <INT> is an integer of type (integer 1 *) Normally, one might add this layer functionality in a wrapper function. However, in so much as #\~ is a macro-character it might make sense to directly accommodate for a default w/r/t filling. This would come in especially handy around documentation related contexts, i.e. for `CL:DOCUMENTATION' one could dynamically bind *read-tilde-refill* to suit particular filling needs. read-time string concatenation - Didier urn:md5:9a206541113a6dad045fec664543c553 2011-06-22T09:18:17+02:00 2011-06-22T09:18:17+02:00 Didier @Xach So you mean just use a function to do the concatenation instead of using a macro character? Anyway, using || as a function name is neat ;-) read-time string concatenation - aerique urn:md5:1ebe4899b541db5f1ebdf5d049827ea7 2011-06-22T00:07:49+02:00 2011-06-22T00:07:49+02:00 aerique I've always used Paul Graham's "mkstr" function for this since I first came across it in On Lisp. <a href="http://www.mail-archive.com/alexandria-devel@common-lisp.net/msg00340.html" title="http://www.mail-archive.com/alexandria-devel@common-lisp.net/msg00340.html" rel="nofollow">http://www.mail-archive.com/alexand...</a> <a href="http://unintelligible.org/onlisp/onlisp.html#SEC35" title="http://unintelligible.org/onlisp/onlisp.html#SEC35" rel="nofollow">http://unintelligible.org/onlisp/on...</a> read-time string concatenation - David urn:md5:6cfc3a5863fcfe48e232d71165e9a1d4 2011-06-21T21:33:06+02:00 2011-06-21T21:33:06+02:00 David Great, I like your hack. I suffered it too. I usually break the docstrings, but extra newlines are introduced in this way. Therefore, I use a convention to specify lines: single newlines are ignored and double newlines are replaced by single ones. However it does the indentation problem unresolvable. read-time string concatenation - Xach urn:md5:221f2f566932949d67ac4eb5887ceec9 2011-06-21T20:30:37+02:00 2011-06-21T20:30:37+02:00 Xach You could avoid alignment issues by writing a function with a short name and passing the strings as argument. SQL's concatenation operator is ||. You could abuse CL's multiple escape syntax to name a function: (defun || (&rest strings) ...).
