<jmd>Is this still true: "Guile has no understanding of multi-byte characters, and string functions won’t recognise character boundaries in multi-byte strings." ?? <ft>(string->list "föo") → (#\\f #\\ö #\\o) <ft>That's in a UTF-8 locale. <jmd>ft: So the answer to my question then is "no" ? <ft>jmd: Yes. That o-umlaut is a multibyte character in utf-8 encoded strings. <jmd>Ok. So that sentence needs to be removed from the manual then. <ft>Oh, yes. I think that whole paragraph can be ruled out. <janneke>how can I re-use symbol import renaming like this, over several modules? <janneke>#:use-module ((oop goops) #:renamer (lambda (x) (if (eq? x '<port>) 'goops:<port> x))) <janneke>i failed to use a pre-defined goops-rename function in stead of the lambda <lloda`>janneke: I can't answer that, but you could also use #:select ((<port> . goops:<port>)) <janneke>lloda`: thanks...I could not find a wildcard/rest option for #:select <janneke>...don't really want to enumerate all other symbols <lloda`>you want to prefix every symbol in the module or only some? there's symbol-prefix-proc which works for me, otherwise the r6rs (import) form has a (prefix) subform <lloda`>re: not being able to use your function in #:use-module <jmd>What magic do I have to perform to get a utf8 encoded string to display properly? <jmd>(display "Grüß") for example? <daviid>jmd: look for setlocale and set-port-encoding! in the manual <lloda`>that works out of the box here. What do you get from (setlocale LC_ALL)? <daviid>lloda`: you're using 2.2, in 2.0 it needs to be set to work <jmd>daviid: Ahh set-port-encoding! is what I need. Thanks. <jmd>lloda`: Indeed one would have expected setlocale to have taken care of this, but that appears not to be the case. <jmd>- at least not in Guile 2.0.13 <daviid>cmhobbs: refering to some passed log, any reason why you're not using the latest stable? 2.0.13 has major iprovments against 2.0.11 <daviid>jmd: 2.0 does _not_ use utf8 has its default encoding, you have to tell guile ... 2.2 does ... <cmhobbs>the last time i installed guile with guix, it was 2.0.11 <cmhobbs>the emacs that i compiled myself (and needs updating, too) can't find the guile binaries that guix provides <cmhobbs>i just needed to hammer some code out and used what i had on hand <lloda`>daviid: good to know, I moved to 2.1 ages ago <lloda`>daviid: I wanted to ask, since you found out about repl-print in (system repl common), did you also find what one needs to fix to truncate output in error messages? <daviid>lloda`: does it not work for error output? i mean using truncate-print ... <daviid>cmhobbs: i would talk to #guix about that, why not the emacs package from guix? <cmhobbs>cmhobbs: guix's package is probably up to date at the moment, i installed this months ago <cmhobbs>and i built emacs from source before i had installed guix (again, many months ago) <daviid>cmhobbs: ok, just being curious, but you probably should try to use the latest stable, and using guix but 2.0.11 is kind of ironic :)?!? guix has guile-next by the way ... guix has everything you need to hack using guile... obviously :) <daviid>lloda`: truncated-print [not truncate-print] <daviid>jmd: guix has guile-next as well, which today is 2.1.6 <daviid>lloda`: have to run, bbl, here in the repl this above mentoned fix also works for errors, but maybe you're talking about changing (current-output-port), then i didn't try that... <janneke>lloda`: i'm going to try eval-when, thanks <janneke>my use case is that i only want to prefix /one/ symbol <janneke>and don't want to duplicate [the implementation of] that renamer-lambda in every module <lloda`>sneek: later tell daviid I use this in my .guile http://paste.lisp.org/+78MJ and it doesn't work on errors. E.g. > (make-array 0 2000) will go through the hook but (throw 'hello (make-array 0 2000)) will print the full array. <lloda`>janneke: you could define a module just for the rename and re-export the prefixed names to everyone else <roelj>How can I make sure code uses the ice-9 'format' instead of the standard 'format' function? <roelj>Does this automatically happen when I add #:use-module (ice-9 format)? <random-nick>when you use a module that exports a binding with the same name as something in you environment, it'll overwrite it <davexunit>civodul: I can't tell, is kastrup angry with you on guile-user? <civodul>but apparently i wrote something stupid <roelj>My format line is larger than 80 characters, can I split it up some way? <lloda`>(string-append "first part" "second part") <roelj>lloda`: Well, it wants a string that isn't dynamically put together I believe <roelj>lloda`: "just" a warning indeed :) <roelj>Is there another way without the warning? <roelj>Actually, I don't get the warning anymore.. <davexunit>the partial evaluator ought to be able to figure that one out <civodul>it can't, because Scheme strings are mutable, unfortunately <civodul>IOW, (string-append "a" "b") cannot be reduced to "ab" <davexunit>yeah but nothing else refers to those things in this case <civodul>but it's passed as an argument to a function that could do anything with it <davexunit>I don't see how that's different than passing a string <davexunit>you're still passing a string to a function that could do anything <davexunit>pre-evaluating the string-append seems fine. I guess I'm just not getting something. <civodul>the function could want a fresh string that it can mutate <civodul>or it could check the pointer identity of the string <civodul>things that are rare in practice, but possible ***dje_ is now known as xdje
<daviid>what is the name of the math operation which consists of taking values in a cetain range and -> another range, like from [0.0 255.0] -> [0.0 1.0] ? is it normalizing/normalization ? <sneek>daviid, lloda` says: I use this in my .guile http://paste.lisp.org/+78MJ and it doesn't work on errors.
