I have the following:
$$\frac{5\; \textup{kilometers}}{\textup{hour}}=\frac{10\; \textup{kilometers}}{t}$$
but it's rendering like this:
Is this not supported by MathJax?
\textup is not available in MathJax. You can replace it with \mathrm.

What does the following syntax mean?
use tokio_tungstenite::{connect_async, tungstenite::protocol::Message};
Is it equivalent to this?
use tokio_tungstenite::connect_async;
use tokio_tungstenite::connect_async::tungstenite::protocol::Message;
I doubt it: tokio_tungstenite::connect_async::tungstenite::protocol::Message is not a symbol.
It is equivalent to:
use tokio_tungstenite::connect_async;
use tokio_tungstenite::tungstenite::protocol::Message;
I tried to do it like this:
await message.channel.send("**" + current_text + "**")
But it doesn't work. It will show the result like this:

Hey
**
For this, I highly recommend using F-Strings. F-Strings allow you to directly call an variable from a string. This should be easier for you to implement markdown since you can do f"**{current_text}**" and {current_text} will be replaced with the according variable.
I switched over from add_ch to having to use add_wch which caused me to also have to change using the various ACS_ special drawing characters to the WCS_ version. The problem I found is that the WCS_ version is not a FULL block, but only a partial block whereas the ACS_ is the proper FULL block. Is there a way to fix that?
TIA!!
It appears to be a ncurses bug. They define WCS_BLOCK as 0x25AE but that is the "Vertical Rectangle". The correct definition should have been 0x2588 which is the "Full Block". So you have to create your own cchar_t and use that. Something like:
wchar_t wch[2];
wch[0]=(wchar_t) 0x2588;
wch[1]=0;
cchar_t cch;
setcchar(&cch, wch, WA_NORMAL, 0, NULL);
I want a Tk::Frame to look like a LCD. Inside the frame I have a Tk::Label and a Tk::Entry. Does anyone know a font name or method to do this, maybe a Perl module?
I've used Steve Lidie's Tk::LCD to make an alarm clock, but had to hack in a few missing features.
How do I do equivalent of python's str.split in DrScheme? SRFI-13 doesn't seem to have it provided.
regexp-split, probably, with regexp-quote on the string first to make it not behave like a regexp.
string-tokenize in SRFI-13
