Hello, I have a question on StackOverflow. Wondering if someone could give it a whirl. It's about separating GUI code from main program and callbacks
<nisstyre>
how do I construct a fixed length sequence of bits in Racket? I want to do something like #b0011111111100000000000000000000000000000000000000000000000000000 and have it always be 64 digits
<nisstyre>
I'm trying to do some visualizations of how IEEE 754 floats work so I need basically 32/64 bits to play around with
<vraid>
a bit vector?
<nisstyre>
(I'm calculating the exponent/mantissa myself)
<nisstyre>
I just want a nice syntax to write it out as well
<nisstyre>
I guess I can make a function to fill it out
<nisstyre>
I guess I would then represent it as a list of 1/0
<nisstyre>
oh, string->bit-vector is what I want

morning
<gour>
does racket's gui (GTK3) work under Wayland under Linux?

<mceier>
you can try it yourself: "export GDK_BACKEND=wayland" and run drracket; not sure if it will work
<gour>
ok. don't have (dr)racket installed, just curious evaluating few language for potental gui desktop project. (one alternative is Eiffel which is probably at the other side of language's spectrum) :-)

I just checked under mutter on fedora and drracket seems to require X11 (ignores GDK_BACKEND and requires DISPLAY environment variables)
<gour>
mceier: thank you!
<mceier>
oh wait... gour I forgot I'm using XFCE now, lol. Drracket works inside weston
<gour>
mceier: i'm on gnome, i'll try for myself (soon)
<mceier>
ok

Does CS version already increase Racket's performance?

nvm seems like it works natively?

yes, I was trying on XFCE at first (not mutter), which is not a wayland compositor
