<alextee[m]>i want to call a proc on each element in a list, and i also want to know the index of the element in that proc. is there a function that does this?

<alextee[m]>or somehow pass both the element and the list in the proc, so i can calculate the index myself

<alextee[m]>maybe a named let would fit here

<RhodiumToad>do you need to return a constructed result?

<RhodiumToad>you could count the element index in a fold

<alextee[m]>no i just need to display it

<alextee[m]>oh fold looks like it would work here, thanks

<RhodiumToad>(fold (lambda (elem idx) (do-stuff elem) (1+ idx)) 0 mylist)

<RhodiumToad>or something of that ilk

<alextee[m]>thanks!

<RhodiumToad>obviously you could do it with a named-let but then you can do anything with a named-let

<daviid>I fixed/enhanced g-golf for (a) 'interface properties and (b) list-store/tree-model set/get value for 'object column type

<daviid>both fix illustrated in this example - https://paste.debian.net/1143648/ - line 37 for (a) and lines 36, 62, 65 67, 68 for (b)

<rlb>Is there a "Local Varables" setting to select the scheme "implementation" for scheme-mode? i.e. chicken vs guile vs...?

<rlb>(wrt emacs)

<rlb>s/Varables/Variables/

<dsmith>rlb: I don't think so for bare scheme mode. But probably is for geiser.

<rlb>maybe that's what I'm seeing?

<rlb>(in the mode line)

<rlb>normally says Guile when you have #!/...guile, but doesn't if you need some mess that execs guile further down in the #!...!# block comment, and so I was trying to fix that.

<dsmith>rlb: geiser-guile--guess in geiser-guile.el

<rlb>dsmith: ahh, thanks. I'll take a look.

<str1ngs>I think the guile mode comes from geiser

<str1ngs>daviid: looks good daviid thanks.

<dsmith>rlb: file-local-variable: geiser-scheme-implementation

<dsmith>rlb: Thanks for the reminder. I was just wanting this the othe day.

<rlb>Hah, your welcome? (Thanks.)

<wingo>wow nice post on type inference in cps!!! http://seanplynch.com/blog/understanding-the-guile-type-inferencer.html

<alextee[m]>which module provides string-replace-substring? the manual doesn't mention

<alextee[m]>oh it does nvm

<alextee[m]>(use-modules (ice-9 string-fun))

<alextee[m]>i still get "In procedure module-lookup: Unbound variable: string-replace-substring"

<RhodiumToad>where is it in the manual?

<alextee[m]>RhodiumToad: 6.6.5.12 Miscellaneous String Operations

<RhodiumToad>not seeing it

<RhodiumToad>in which version?

<alextee[m]>ah that's my local copy, maybe it's outdated

<alextee[m]>RhodiumToad: it's there

<RhodiumToad>for which version?

<alextee[m]>6.6.5.12 Miscellaneous String Operations last part

<alextee[m]> https://www.gnu.org/software/guile/manual/guile.html#Miscellaneous-String-Operations

<alextee[m]>im using guile 2.2.7 btw, maybe this is for guile 3?

<RhodiumToad>yes

<RhodiumToad>it's new in guile3

<RhodiumToad>or at least newer than 2.2.7

<alextee[m]>ah i see. i'll copy this then https://lists.gnu.org/archive/html/guile-devel/2013-09/msg00029.html

<chrislck>this is a function with lots of history

*alextee[m] is writing a gsettings schema generator in guile: https://paste.debian.net/1143702/

<alextee[m]>result so far: https://paste.debian.net/1143703/

<alextee[m]>so much better than editing xml!

<chrislck>why not use sxml->xml ?

<alextee[m]>oh didnt know about that. not sure how that would work

<alextee[m]>looks pretty complicated

<rekado>alextee[m]: but it isn’t!

<rekado>it lets you convert an S-expression representation to valid XML

<rekado>(sxml->xml '(enum (@ (id "org.zrythm.Zrythm.audio-backend-enum")) (value (@ (nick "none") (value "0")))))

<alextee[m]>oh! great! let me try that

<rekado>@ introduces attribute lists

<rekado>the rest is as you’d expect

<rekado>also remember to use quasiquotation and procedures to generate stuff

<alextee[m]>could probably use more compex examples in the manual

*alextee[m] has no idea what s-expressions or quasiquotations are

<chrislck> https://pastebin.com/DL4YTyvk

<rekado>quasiquote is the toggle switch

<rekado>` means “data mode”

<rekado>, means “code mode”

<rekado>`(this is data but ,(+ 1 3 4) is code)

<rekado>an S-expression is just a fancy name for all of these parentheses and what they enclose.

<alextee[m]>chrislck: thanks!

<alextee[m]>oh i see

<chrislck>every guile prog is an s-expression

<alextee[m]>haven't consciously used ` or , yet so not sure how they work, although i see them in guix packages

<alextee[m]>so in the example above, this is an S-expression? '(enum (@ (id "org.zrythm.Zrythm.audio-backend-enum")) (value (@ (nick "none") (value "0"))))

<rekado>the example above is equivalent to '(this is data but 8 is code)

<rekado>alextee[m]: yes

<rekado>it’s just data

<rekado>a nested list

<chrislck>so is this: '(bla)

<chrislck>so is this: #f (I think)

<alextee[m]>ah i see

<chrislck>alextee is starting to see the matrix

<alextee[m]>:D the awakening

*chrislck read SXML and SSAX chapters several times to finally grasp it

<chrislck>using sxml will "guarantee" that your XML is well-formed

<RhodiumToad>eh.

<chrislck>ok it will be easier to write well-formed xml

<alextee[m]>doesn't look well-formatted to me: <enum id="org.zrythm.Zrythm.audio-backend-enum"><value nick="none" value="0" /><value nick="alsa" value="1" /><value nick="jack" value="2" /><value nick="portaudio" value="3" /><value nick="sdl" value="4" /><value nick="rtaudio" value="5" /></enum>

<alextee[m]>probably needs some flags to change how it outputs things

*alextee[m] reads the SXML chapter

<RhodiumToad>well-formed, not well-formatted

<alextee[m]>oh

<vms14>Hi, I'm trying to load a gnome guile library in netbsd, but I don't know what I should do, I have the gnome libraries in a different location from the guile stuff and trying to add it with setting %load-compiled-path

<vms14>(set! %load-compiled-path (list "/usr/pkg/guile/2.2/lib/guile/2.2/ccache" "/usr/pkg/guile/2.2/lib/guile/2.2/site-ccache" "/usr/pkg/lib" "/usr/pkg/libguile-gnome-2/"))

<vms14>gnome stuff is in /usr/pkg/lib/libguile-gnome folder

<vms14>and guile stuff in /usr/pkg/guile/2.2/ it has a bunch of folders there like lib, man, include, share, bin and so on

<dsmith-work>Wednesday Greetings, Guilers

<vms14>but gtk.so is in /usr/pkg/lib/guile-gnome-2/libgw-guile-gnome-gtk.so

<vms14>how I'm supposed to load those paths?

<dsmith-work>vms14: I don't have an answer for you, but just be patient. Might take a day or so.

<RhodiumToad>vms14: did it install a gnome-2.scm in the guile "site" dir?

<RhodiumToad>vms14: I made a freebsd port for guile-gnome so I have some idea of what's going on

<RhodiumToad>the theory is that you should be able to import the (gnome-2) module and it sets up all the paths for you

<vms14>RhodiumToad: found it at /usr/pkg/share/guile-gnome-2/gnome/gw/gtk.scm

<RhodiumToad>no

<vms14>so I should try to add that to the path, but which "path" variable? %load-path/

<RhodiumToad>where is gnome-2.scm

<vms14>/usr/pkg/share/guile/site/gnome-2.scm

<vms14>hmm

<RhodiumToad>right. so you should be able to just do:

<RhodiumToad>(use-modules (gnome-2) (gnome gtk) (gnome whatever...))

<vms14>does not find the module

<vms14>it seems I have to add a bunch of folders to some paths

<RhodiumToad>what exactly is not found?

<RhodiumToad>and what is your load path before you mess with it?

<vms14>(use-modules (gnome-2))

<vms14>While compiling expression:

<vms14>no code for module (gnome-2)

<vms14> "/usr/pkg/guile/2.2/lib/guile/2.2/ccache" "/usr/pkg/guile/2.2/lib/guile/2.2/site-ccache"

<vms14>that's the load path

<vms14>but the gnome wrapper stuff is installed in different paths

<RhodiumToad>that's %load-compiled-path ? what is %load-path ?

<vms14>("/usr/pkg" "/home/vms/.emacs.d/elpa/geiser-20200426.2152/scheme/guile/" "/usr/pkg/guile/2.2/share/guile/2.2" "/usr/pkg/guile/2.2/share/guile/site/2.2" "/usr/pkg/guile/2.2/share/guile/site" "/usr/pkg/guile/2.2/share/guile")

<RhodiumToad>but not /usr/pkg/share/guile/site ?

<vms14>just that

<RhodiumToad>that looks like a somewhat confused default

<vms14>so, I've just need to add /usr/pkg/share/guile/site to load-path?

<RhodiumToad>yes

<vms14>it seems I'll have to add several folders to several load paths

<vms14>I'll try thanks

<RhodiumToad>no

<RhodiumToad>just add that one directory to that one path, nothing else

<vms14>ohhh, done

<vms14>thanks you so much

<vms14><3

<RhodiumToad>(my freebsd port of guile-gnome is blocked on a portmgr review, unfortunately, but I use it locally)

<vms14>you can switch to netbsd :D

<vms14>the team is really awesome

*RhodiumToad would rather not :-)

<vms14>:O

*vms14 cries

*dsmith-work ran netbsd on a cobalt qube for a while.

<RhodiumToad>the annoying thing about going a freebsd port for guile-gnome was having to patch the hell out of the autoconf script to make it respect --without-BLAH options

<dsmith-work>vms14: So how is guile on nbsd?

<vms14>dsmith-work: can't tell you really, just installed it, I don't even know scheme, I use common lisp with sbcl

<vms14>and I could say support for sbcl in netbsd is kinda bad :/

<vms14>no thread support and most libraries using ffi won't work since they assume linux paths

<dsmith-work>Just curious becuse I know nbsd is very picky about posix things. No linux-isms there!

<vms14>usually in netbsd is a hell to install libraries in a not mainstream language since netbsd tends to separate in folders what it comes in base and what the user has installed

<RhodiumToad>hm, freebsd is no different in that respect?

<vms14>/usr/pkg is where your installed stuff goes, so you have /usr/lib and /usr/pkg/bin

<RhodiumToad>(just /usr/local rather than /usr/pkg)

<vms14>I should work on that someday and try to add a way to make languages find their libraries

<vms14>btw thanks for helping me with that

<civodul>wingo: i'm testing a trick to avoid malloc/free/dynwind in most cases for POSIX subrs that take a string

<civodul> https://paste.debian.net/1143749/

<civodul>i'll post a patch & figures soon if that makes sense to you

<wingo>civodul: nice! do we have internal pointers enabled?

<wingo>otherwise returning a pointer into a string could be a hazard

<civodul>ah good point, we don't have internal pointers

<civodul>and STRINGBUF_CONTENTS is a pointer in the middle of the stringbuf

<civodul>but OTOH, for this use case, it's fine because the Scheme string outlives the C pointer returned

<civodul>WDYT?

<wingo>civodul: i am not so confident making the assertion that a C compiler wouldn't remove the SCM. depends on the use site but it's a bit iffy

<wingo>one of those occasions where what one would want is C++ with RAII :)

<dsmith-work>sneek: botsnack

<sneek>:)

<dsmith-work>sneek: seen rlb

<sneek>rlb was last seen in #guile 18 hours ago, saying: s/your/you're/.

<dsmith-work>sneek: testing is Testing, Testing, One Two Three..

<sneek>I'll keep that in mind.

<dsmith-work>sneek: testing?

<sneek>Someone once said testing is Testing, Testing, One Two Three..

<dsmith-work>sneek: forget testing

<sneek>Consider it forgotten.

<dsmith-work>sneek: testing?

<dsmith-work>sneek: botsnack

<sneek>:)

<dsmith-work>goodbot

*sneek wags

<alextee[m]>is there a variant of (format) that returns the string instead of printing it?

<alextee[m]>oh #f

<civodul>wingo: hmm even if it were removed, the SCM is still in the VM stack no?

<wingo>civodul: that is not guaranteed. in practice though, yes.

<guix-vits>sneek: seen sneek?

<sneek>Sewni was in (here?) 7 months ago, saying: I didnt realise you were using the bot :P.

<dsmith-work>alextee[m]: Also can be a port, so you could pass a string port. Might be useful for building a string a piece at at time.

<guix-vits>sneek: seen sneek?

<sneek>Sewni was last seen in (here?) 7 months ago, saying: I didnt realise you were using the bot :P.

*guix-vits "ah, some sort of regex"

<dsmith-work>alextee[m]: I wouldn't be surprised if #f is implmented by printing to a string port internally and then returning the string.

<alextee[m]>so many ways to do things in scheme, fun

<civodul>wingo: ok, i've sent what i have to guile-devel + you!

<dsmith-work>Hah!

<dsmith-work>alextee[m]: Indeed, #f uses (open-output-string)

<dsmith-work>sneek: botsnack

<sneek>:)

<dsmith-work>Interesting!

<dsmith-work>So the problem I was having with for-each being undefined goes away when using srfi-1

<dsmith-work>(which also defines a for-each)

***dsmith-work is now known as someoneelse

<someoneelse>sneek: later tell dsmith-work It's working.

<sneek>Got it.

***someoneelse is now known as dsmith-work

<dsmith-work>Ok

<sneek>Welcome back dsmith-work, you have 1 message!

<sneek>dsmith-work, someoneelse says: It's working.
