[racket-users] Re: List-box% using percentages to resize multiple columns

I believe the message means that the width you specify is greater than the max value you also specify. That is, you probably call it as (set-column-width i 715 0 596), which could happen if 'perc' is greater than 100. You can verify that by printing out all the values and checking them.

And here's an even smaller one along the same lines: #lang racket/base (define h '#hash(("mail-server" . "smtp.sendgrid.net"))) (define h2 (hash "mail-server" "smtp.sendgrid.net")) (chaperone-of? h2 h) (equal? h2 h) Note that the `equal?` comparison always works, the bug appears to be just in

Here's a program that, when run prints #t or #f depending on whether or not there is a .zo file. #lang racket/base (require racket/contract) (define h '#hash(("mail-server" . "smtp.sendgrid.net"))) (define h2 (for/fold ([h h]) ([(k v) (in-hash h)]) (hash-set h k v))) (chaperone-of? h2 h)

Re: [racket-users] Using the base language’s get-info function with make-meta-reader

Alright, I’m finally taking a look at this (and looping the users list back in). I think, unfortunately, your (Alex’s) change isn’t quite sufficient: having access to the get-info function isn’t enough. The read and read-syntax functions need access to the lambda returned by the base language’s

This looks like a contract system bug (or a compiler bug). If I change reducing-2.rkt to this: #lang racket/base (require racket/contract racket/hash) (define/contract hash-union2 (-> (hash/c string? string?) (hash/c string? string?) (hash/c string? string?))

[racket-users] List-box% using percentages to resize multiple columns

I'm trying to get a list-box% subclass to work with min-widths and percentage values, but I'm unable to figure out the correct total width to calculate the actual widths. Inside the listbox, I store the percentages in percentages and the minimum-widths in minimum-widths: (define/override

I'm unable to replicate this on two different machines, with up to date Racket. Can you try it with a snapshot? Here's what I did: [samth@huor:~/tmp plt] cat > reducing-1.rkt #lang racket (require "reducing-2.rkt") (define bad (modified-test-conf (hash "a" "b")))

Sam, On the off-chance that the snapshot I used was somehow “stale”: I have just done a fresh racket install from git; I have 'raco pkg install -i pict3d' And retried the test. I still get the type errors. Tim On 07/09/16 16:47, Tim Brown wrote: > :-( > > Latest nightly "snapshot
