Unfortunately, that seems to be a problem in the library. You can see the source here: http://planet.racket-lang.org/package-source/toups/functional.plt/1/1/monads.rkt and it depends on a utilities collection that it does not include. Sam On Wed, May 31, 2017 at 11:53 PM,

Re: [racket-users] How to install a planet package?

I just installed from the version 6.9 shell script. I did enter 'Y' for all dependencies. If I switch to (require (planet toups/functional:1:1/monads)) I get the error: /home/kk/.racket/planet/300/6.9/cache/toups/functional.plt/1/1/monads.rkt:3:9: collection not found

Installation from Planet means that you have to use the special planet require syntax, in this case: (require (planet toups/functional:1:1/monads)) Sam On Wed, May 31, 2017 at 9:44 PM, wrote: > Probably a basic question, but when I run: > > raco planet install toups

Yes. Did you allow Package to install all dependencies? I just ran it and the installation completed flawlessly. GIT HEAD Racket version. > On May 31, 2017, at 10:07 PM, keccak...@gmail.com wrote: > > Thanks. When I run the planet install it does appear to work. Running > > raco pkg

Thanks. When I run the planet install it does appear to work. Running raco pkg install functional also appears to work, but I still see an error scratch.rkt:5:9: collection not found for module path: functional/better-monads collection: "functional" in collection directories:

There is a ‘functional’ package on the Package server. Try that for now? It’s possible that Planet went off-line. > On May 31, 2017, at 9:44 PM, keccak...@gmail.com wrote: > > Probably a basic question, but when I run: > > raco planet install toups functional.plt 1 1 > > to install a

Probably a basic question, but when I run: raco planet install toups functional.plt 1 1 to install a package, I still get an error for the 2-line script #lang racket (require functional) that this collection is not found in /usr/racket/collects/ I have run every other seemingly related

In addition to what others have mentioned, at this scale, you might get significant gains by adjusting your s-expression language. For example, instead of this: (pmem_flush (threadId 140339047277632) (startTime 923983542377819) (elapsedTime 160) (result 0) (addr 0x7fa239055954) (length

Re: [racket-users] Performance of the Racket reader

Can you explain why you create a lazy stream instead of a plain list? Your code is strict in the stream so the extra memory for a stream is substantial and probably wasted. Perhaps the below is simplified and you really need only portions of the lazy stream. — Matthias > On May 31, 2017,

[racket-users] Performance of the Racket reader

I've written a command-line tool in Racket to analyze the files produced by a tool that traces accesses to persistent memory by an application. The traces are large: about 5 million records per second of application run time. While developing the tool in Racket was a pleasant, productive, and
