04:22 <williewillus> I'm reading the ref page on breaks, and it's not clear to me which thread will receive a break if I e.g. type Ctrl+C on the CLI. Is it just a random thread that has then enabled?

04:23 <williewillus> and I'm guessing all threads are eligible for breaks by default? So any background threads I spin off should all disable breaks as the first thing they do

17:07 <msiism> I've asked about this yesterday, but had to leave then: I'm tryign to find a reasonable way to transform a bunch of lines from an input file into a hash table.

17:08 <msiism> Here's what I have so far: https://paste.debian.net/plainh/8ed723b5

17:09 <msiism> Variant II seems more useful to me because I need to keep the input data cached to work on it.

17:10 <msiism> I'm generally haveing a bit of trouble telling when racket stores a value vs. only storing the way to generate that value.

17:12 <msiism> It seems to me that, most of the time, if you say (define X (formula)), then evey time you say X, Racket will run that formula, i. e. procedure.

19:59 <jA_cOp> when you do `(define foo bar)`, `bar` is only evaluated once, when the define expression is evaluated. When you subsequently reference `foo`, the same value is accessed every time (unless later changed with set!).

20:01 <msiism> Oh, now that makes a few things a lot easier, doesn't it? :)

20:01 <jA_cOp> Note that function definition also uses the `define` form, so it looks similar, e.g. `(define (foo) bar)`. In this case, foo is a function, and its body is evaluated every time it is called. However, just like other definitions, you can reference `foo` without calling it, if you want to say, pass the function to another function (aka higher-order function, like `map`).

20:01 <jA_cOp> The guide has details and examples https://docs.racket-lang.org/guide/syntax-overview.html#%28part._.Definitions%29

20:01 <msiism> Okay, thanks.
