3:43:24 beach Good morning everyone!

3:56:57 tourjin I opened emacs ctrl+x 3 . and compiled ctrl+c ctrl+c then error occured . left windows shows the errors. but how can I go back to original file?

3:57:48 no-defun-allowed Press q on the error window.

3:58:29 tourjin oh. thank you.

4:13:23 tourjin in my file I wrote a defparameter on first line. then I wrote a defun using that parameter . but if I compile it . error says undefined variable: *MYVAR*. is slime different from writing in command line?

4:16:28 aeth tourjin: are you sure both are *MYVAR*?

4:18:00 tourjin yes

4:18:07 tourjin hm.. I found something

4:18:41 tourjin if I move cursor on that line and ctrl +c ctrl + c . then it runs.

4:20:08 tourjin is this normal?

4:25:21 jiny ** NICK tourjin

4:27:57 pjb tourjin: C-c C-c only compiles 1 defun. Having stuff in buffers, or even in files doesn't help at all.

4:28:11 pjb tourjin: use C-c C-k to compile the whole file.

4:28:36 tourjin hm.. ctrl+c ctrl+c just compiles one line or one block where the cursor is . is this normal?

4:28:56 tourjin oh yes pjb i found it now.

4:29:06 tourjin ok c-c c-k

4:29:31 tourjin thank you. that was what i'm looking for.

4:30:31 pjb tourjin: it's not lines or blocks, it's s-expressions.

4:33:55 tourjin how do u memorize the whole keywords? C-c C-c , I can figure it out it's a acronym of compile. what does k stand for?

4:34:49 beach tourjin: You don't. Your fingers will remember at some point and you no longer have to think about it.

4:35:20 beach tourjin: And please don't use abbreviations such as "u" for "you". Turn on your abbrev processor.

4:38:06 tourjin thank you pjb you remind me i have a lot of docs to read. I don't get what s-expressions means. i see . i shoud'nt use 'u'. thank you. by the way it's not abbrev processor. I even don't know how to use abbrev processor in irc. it was me who typed 'u'. :-)

4:38:46 aeth C-c C-c is for Command: Compile function. C-c C-k is for Command: Kompile file, since C was taken. at least, that's my justification, who knows what the authors thought?

4:38:59 aeth s/Compile function/Compile form/

4:40:58 tourjin I think that's a good tip for justification of compile and kompile. thank you aeth

4:45:10 beach tourjin: If you use a decent program for IRC, such as ERC for Emacs, it will have an abbrev processor, so that you can define abbreviations. For example, you can make "u" expand to "you" automatically every time you type it as a word.

4:45:36 beach tourjin: I never type "Good morning everyone!" for instance. I just type "gme".

4:46:59 beach tourjin: Not only does it save a lot of typing. It also means fewer typos.

4:51:13 tourjin i see. probably most of you must use irc in emacs. but I'm really really new to emacs or lisp.

4:54:38 beach Then I guess you just have to do it the hard way, i.e. type everything out. Oh, the pain that people inflict on themselves by using mediocre tools.

4:56:26 tourjin I would have'nt thought about irc if it was easy to find informations on lisp. now I get there was full of online documents out there and experts who will give me tips for solutions as much as even I can't comsume. thank you.

5:01:32 aeth I don't use IRC in Emacs because I prefer having it in a separate program. I think I might be in the minority, though. I don't even use IRC locally, I ssh into a server and have a terminal IRC running in tmux.

5:03:51 beach aeth: But I am sure it has an abbrev processor, right? I mean, you know to choose your tools.

5:05:45 pjb aeth: you can use a different emacs instance for erc, if you prefer it in a separate process.

5:06:14 pjb aeth: this is what I used to do, because of network delays: one emacs to program, one emacs for erc, and one emacs for gnus.

5:06:25 pjb But nowadays, I just have one emacs for all.

5:11:03 aeth pjb: I would if I did, even if I ran IRC locally.

5:11:34 LdBeth Good evening

5:17:24 beach Hello LdBeth.

5:18:49 aeth pjb: I often restart emacs several times a programming session mainly because that's the easiest way to close a bunch of buffers

5:24:00 beach As far as I am concerned, people are free to inflict pain on themselves by using mediocre tools, but they shouldn't export that pain to others by (say) showing badly indented code or exposing unexpanded abbreviations such as "u".

5:29:05 thijso I use irssi as my IRC client, mainly for historical reasons... And indeed, I have it running on a separate machine inside a screen

5:29:12 thijso Good morning btw

5:33:47 beach Hello thijso.

5:35:34 aeth thijso: I used screen+irssi for a very long time when I switched to Linux a very long time ago, but I evnetually upgraded to tmux+irssi because of the superiority of tmux

5:35:49 aeth *eventually

5:36:35 pjb aeth: (defun kill-all-buffers () (interactive) (dolist (buffer (buffer-list)) (kill-buffer buffer)))

5:45:23 thijso aeth: screen does what I need it to do. I've heard of tmux and have this idea to check it out one of these days. Like for a couple of years, now... ;)

6:12:33 jeosol Good morning all

6:14:46 thijso Is there a (semi-)convention for marking function names internal/external/exported and such? I've seen, for example #make-thread in bordeaux-threads, but that's mainly to distinguish it from other make-threads, I think?

6:15:08 thijso sorry, it was %make-thread, not #

6:15:25 thijso morning, jeosol, btw

6:15:50 thijso much too early morning, in fact...

6:15:55 Shinmera Just don't export it

6:16:28 Shinmera The % is typically for functions that are closely tied to some other context and are thus "extremely internal"

6:16:38 thijso Shinmera: yeah, obviously, but it's more a style thing I had in my mind. But there isn't really, probably

6:16:47 thijso Right

6:17:36 thijso Well, I basically have something now where I have an internal function that logically should have the same name as an external one

6:17:51 thijso I'll probably go with % then

6:17:52 pjb thijso: you write the name of exported functions explicitely in the :export list of the package. This is the convention.

6:26:24 jeosol If I have an image saved from a previous run, and restart sbcl with the core file. I create a new module (defsystem) and tried to load it in and was getting errors. I am able to load the new system elsewhere through (e.g., fresh sbcl)

6:32:09 pjb jeosol: so what? This morning, I got some raisin I saved, out of the fridge, and a firefly was eaten by a bird in the street.

6:35:05 pjb jeosol: try again with: (handler-case (asdf:oos 'asdf:load-op :your-system) (error (err) (prin1 (class-name (class-of err))) (terpri) (princ err) (terpri)))

6:35:08 jeosol haha, there you go again. it's not working. I am getting errors

6:35:28 jeosol pjb: thanks, let me try that

6:35:35 pjb jeosol: you're not getting random errors, you're gettint a very specific error!

6:35:57 pjb If you don't take the very specific information from this very specific error into account you won't be able to solve your problem.

6:36:47 thijso I think what pjb is getting at is that it helps if you actually tell us exactly *what* errors you're getting, jeosol

6:37:13 pjb also, what expression you use to load it.

6:38:08 jeosol I use (ql:quickload ...)

6:38:49 pjb So: (handler-case (ql:quickload :your-system) (error (err) (prin1 (class-name (class-of err))) (terpri) (princ err) (terpri)))

6:39:41 jeosol I get component: name not found.

6:40:06 jeosol Thanks. Just a tired now. btw raisin and firefly comment was funny

6:47:11 pjb jeosol: so what component is not found? Is it your system itself?

6:57:52 jeosol Yeah, the system itself, not sure why. I just rebuilt the whole thing again and resaved the image.

7:00:33 pjb there should be a file named something.asd stored in one directory where quicklisp will search it. For example, in ~/quicklisp/local-projects/

7:01:11 pjb The name of the file doesn't need to be related to the name of the system, but it may help humans to retrieve things. So name it: your-system.asd

8:03:16 tourjin in emacs slime , how can I reuse previous command? upper arrow does'nt work.

8:06:04 tourjin hm.. I found it alt+p. everything works with ctrl or alt keys.
