02:52 <init> hey, I'm coming from clojure, mostly with anticipations eureka while reading HTDP

02:52 <init> I use Emacs, and I am wondering how is specifying BSL as easy adding a top-level #lang?

02:53 <init> s/how is/if

02:53 <init> s/anticipations/anticipations of

02:54 <init> s/as/is

03:13 <init> #lang htdp/bsl should do

03:38 <init> for those of you that use emacs, how do you paste images into the repl?

12:20 <bremner> init: I started a page about htdp languages in racket-mode: https://www.cs.unb.ca/~bremner/teaching/htdp+emacs/

12:21 <bremner> in principle #lang htdp/bsl should work. In practice there are some rough corners

12:22 <init> bremner: these are the exact issues I was faced with

12:23 <bremner> did you solve the image issue? does that variable help

12:23 <init> bremner: which variable?

12:24 <bremner> something about inline images?

12:24 <init> did I post that here, in emacs, or are you a mind reader?

12:24 <bremner> in #emacs

12:24 <init> > racket-images-inline, no did not work for me

12:24 <init> but I am using doom-emacs and might have to dig a bit

12:25 <bremner> m'kay. I think images work in #lang slideshow

12:25 <init> bremner: if you're on vanilla, could you try?

12:25 <bremner> and #lang racket

12:25 <bremner> ok

12:25 <init> (setq racket-images-inline t)

12:26 <init> racket mode did not specify if emacs needed to be built with a particular feature for it to work

12:26 <bremner> GUI emacs, not terminal, right?

12:26 <init> I am using the GUI

12:27 <init> some of the literature suggests that emacs might need to be built with imagemagick support

12:28 <init> check the output of "system-configuration-features"

12:28 <init> mine isn't built with it

12:31 <bremner> what if you change to #lang racket ?

12:31 <bremner> for me the variable has effect with #lang racket, but not #lang htdp/bsl

12:34 <bremner> I have: ACL CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ JPEG JSON LCMS2 LIBOTF LIBSELINUX LIBSYSTEMD LIBXML2 M17N_FLT MODULES NATIVE_COMP NOTIFY INOTIFY PDUMPER PNG RSVG SECCOMP SOUND SQLITE3 THREADS TIFF TOOLKIT_SCROLL_BARS TREE_SITTER WEBP X11 XDBE XIM XINPUT2 XPM GTK3 ZLIB

12:35 <init> oh I see, well at least it works? :)

12:35 <init> just not with htpd/bsl

12:36 <bremner> yeah. I was going to collect a sort of omnibus bug report and send it greg (racket-mode)

14:07 <init> bremner: I assume bsl differs a lot in comparison to racket?

14:07 <bremner> init: it's just a subset, but the error messages are more helpful to beginners

14:08 <init> would it then be possible to go through htdp using #lang racket?

14:08 <init> I'm really only here to learn about how to design programs and not so much racket lol

14:08 <init> I come from Clojure, seeking this knowledge

14:08 <bremner> it should mostly work.

14:09 <bremner> I ended up using Rahgde's "Function Introduction to Computer Science" in class because it does not lean on the image stuff as much

14:09 <bremner> YMMV

14:10 <init> are you a professor?

14:10 <bremner> yes

14:10 <bremner> but not your professor, as the lawyers say :)

14:11 <init> no, give me advice!

14:11 <bremner> sure, if I know

14:11 <bremner> ls

14:11 <bremner> oops

14:11 <bremner> not sure you want advice from me this morning :)

14:12 <init> I have been focusing on learning Clojure for the past 3 months or so, I have a basic hobby project, it's an IRC bot

14:13 <init> I have a incomplete CS background and, no prior programming experience, so I want to learn how to design programs using a functional language

14:14 <init> the paradigms that I see at play with Clojure are, homoiconicity, functional core, imperative shell (encapsulating/limitign side-effects) and REPL based development

14:15 <bremner> htdp is probably a good choice. FICS is worth a look, much more compact, but maybe a bit too mathy for some: https://cs.uwaterloo.ca/~plragde/flaneries/FICS/

14:15 <init> are there any resources you could think of that I should take a look at?

14:17 <init> htdp makes mention of a second volume, htd(components)

14:17 <init> I couldn't find this online

14:18 <bremner> hmm. I have not seen that either

14:19 <init> > This edition of the book drops the design of imperative programs. The old chapters remain available on-line. An adaptation of this material will appear in the second volume of this series, How to Design Components.

14:20 <bremner> hmm. Maybe to appear

17:47 <samth> It doesn't exist

20:41 <init> bremner: what courses come after the one you teach?

20:44 <bremner> init: the main racket using one is one based "programming languages, application and interpretation" by Shriram Krishnamurty (sp?)
