Re: [racket-users] DrRacket 6.5 + OS X El Capitan = slow execution

This might be a wild guess, but are you using typed/racket as the language? On my machine (Windows 7, DrRacket 6.6), if I use #lang typed/racket, evaluate it than type "Hello World" in the REPL, it takes about 2 seconds to display the result (after that it seems to run fast). If I just use

Re: [racket-users] DrRacket 6.5 + OS X El Capitan = slow execution

Okay, thanks. (For the record, I use Mac OS X 10.11 routinely and do not experience this issue, so there must be something something else going on. I'm not sure what guess to make next, but it is interesting that 6.2.1 didn't have this issue.) On Wed, Jul 27, 2016 at 9:45 PM, Ivan Kuzmin

It may be that something went wrong with the date stamps. Can you try opening a Terminal window and Running the command: (quit DrRacket first and you should be able to just paste that command into the Terminal window and hit return) /Applications/Racket\ v6.5/bin/raco setup This should print

[racket-users] DrRacket 6.5 + OS X El Capitan = slow execution

To reproduce: 1. Download DrRacket x86_64 v6.5 [1] 2. Start on OS X El Capitan. 3. Type in "hello world" and press run... It takes about 2-3 seconds to execute this code on my machine. Also "flawed" builds show blinking recycling icon in the bottom right corner while executing the code and

Re: [racket-users] Handling disappeared uses from within syntax classes

Ask Ryan to expose the backtrack continuation. Then accumulate the anti-effects and attach them to the backtrack continuation. If it is thrown, it’ll automatically undo the effects. I bet this will be useful in a more general setting. [See Prolog implementation as embeddings.] > On Jul

Re: [racket-users] racket command-line REPL: Constructor style printing mode?

Thanks for the prompt reply! I managed to install the package. For my current use-case, using the racket in module mode, with the right #lang directive at the top of the .rkt file is enough. For the interactive mode, however, I was expecting something like racket -I 'constructor-style-print

One option is to use Alex Knauth's package quote-bad. https://docs.racket-lang.org/quote-bad/index.html?q=constructor#%28part._.Changing_the_printing_style_to_avoid_printing_bad_uses_of_quote%29 If you want to see how he sets the print handler:

[racket-users] racket command-line REPL: Constructor style printing mode?

Hi, I'd like to use the Constructor printing style in the command-line REPL, so that it behaves the same as in my current DrRacket config, e.g. > (list 1 2 3) (list 1 2 3) Using https://docs.racket-lang.org/reference/printing.html, I've been trying to set (interactively) the right parameters
