This is just a suggestion, that does not help with your current dilemma, a
strategy how you could prevent it in the future:
Create or expand your personal dotfile repository, within that repository
create a folder my-racket-packages, within that folder create a info.rkt:
#lang info
(define
Stepping through the code with the drracket debugger and inspecting the
values on the way may also be a good way to identify areas where your code
doesn't work like you had expected.
Maybe write some more testcases / example applications of your function and
see which inputs already work and

I wonder what about images makes you want to leave emacs, when you run
`racket-run` (racket mode) from a racket module file in emacs it executes
(and enters) that module and then opens a split

Actually the flag version does not work for me.
(I thought it did because on-paint was fast enough not to be noticed that
it was sequentially processing every mouse event with a paint call)

I think in such an environment I would like to control memory usage myself,
or maybe have a #lang that allows very fine grained and low level control
over resources. (outputting lowerlevel code than racket/base).
If you need persistent data-structures they are nice, but often times you

the latest version is saved.
So many different tradeoffs possible ;)

I have a racket gui app that uses a canvas% with overridden on-event and
on-paint methods.
When the user hovers over drawn elements the on-paint is called via (send
this refresh)
to display the element under the cursor with a selection/outline.
Recently I noticed that this has gotten extremely
is useful for snappier user-feedback.
So the next step for me is to look at the differences between the old and
new code.

That is strange, I haven't had that problem.
I assume you are using a sqlite db that is stored in a file? (not an in
memory one because that would be reset everytime?)
Are you sure you aren't doing your updates in some kind of transaction that
remains unfinished for some reason for a long time?
The docs say
style: (listof (or/c 'no-caption 'resize-border 'no-sheet 'close-button)) =
null
so either (style (list 'resize-border)) or (style '(resize-border))

You can't create a hierarchy of menu-items%, because menu-items are always
leaf nodes (a "terminating" node in the hierarchy).
But you can have many nested menu% elements which can have

whether I could see anything else that can be tweaked, I tried a few things
but they didn't improve performance, but it was fun anyway.
Then I though I could try the macro stepper and look at the expansion of

I don't really understand what you want to do exactly.
I think mostly you have to implement it yourself, possibly by using
something like https://docs.racket-lang.org/charterm/index.html or maybe
https://docs.racket-lang.org/lux-charterm/index.html
;jobs" command then lists background processes, "fg" brings back the most
recent one (your terminal app). Thats the simplified description see the
manpages or google for more info on that.
But I have the impression that you want to do all these things within your
application?
schle.
I am not sure about the technical details, but would it be possible to
rename those identifiers with?: (require (rename-in fluent [→ ~>] [→→

I think if you define those arrows as syntax parameters they could be
renamed, but I don't know whether that is the "right" way to do it in

The racket discord is managed quite well, I think it should be added to the
racket website so that newcomers can find it easier, just a thought.
Maybe below the link to slack?

But you can also define two single collection packages that use the same
`(define collection "...")` within the info.rkt.
And that allows you to add modules with single collection packages.
Only tested locally but seems to work.

I am not sure what your intent is with 2 exactly.
Is it to install the package you have checked out with git?
If that's the case change the sequence to:
git clone https://github.com/rebcabin/bleir-sandbox.git
cd bleir-sandbox
git checkout master
raco pkg install
raco setup bleir-sandbox
raco test
