[racket-users] Re: How to work on a package from a released version of Racket?

I hope that there's a better way, however what I ended up doing was this: 1) Install a "Minimal Racket" from http://download.racket-lang.org/releases/6.8/ (scroll down a bit to see these versions). 2) cd path/to/my-clone-of-plot/; raco pkg install 3) raco pkg install main-distribution If you

Re: [racket-users] Re: How to work on a package from a released version of Racket?

I thought raco pkg update was unable to turn a catalog-package into a locally-installed package, but I might have tried it at the time within the directory itself, instead of cd-ing one level up like you said. Thanks for the tip! -- You received this message because you are subscribed to the

[racket-users] What precisely is the type/contract ‘TST’ ?

It appears, e.g., in: (send a-drracket:rep:text display-results results) → void? results : (list-of TST) A search of all racket files shows it used at times for values to be displayed, but I can't find a definition of the term, nor just what it's [presumably] an acronym or abbreviation

Re: [racket-users] How to work on a package from a released version of Racket?

I see the same behavior as you with the v6.8 release. The problem is related to cross-compilation and path conventions. A cross-compiled build (such as the Windows distribution) starts with an "info-cache.rktd" that has paths in Unix format instead of Windows format, and `raco setup` (as run by

[racket-users] Re: Algol

As you say, it works with "#lang algol60", but I can't find "Algol60" in the language selection dialog on DrRacket 6.9.0.1, only R5RS, "Pretty big Scheme" and "ProfessorJ" (which I installed manually). Which version are you using? Which version were you using when it used to work?This may help

Indeed, these docs were written a long time ago. also, (listof any/c) is the same thing as list? in the contract system. Robby On Sun, Apr 9, 2017 at 3:08 PM, Jay McCarthy wrote: > It is legacy. Modern code would just write any/c or list? > > Jay > > On Sun, Apr 9,

[racket-users] Keyboard and Image movement

Hey everyone, I"m new to the racket language and was wondering if anyone can help me explain keyboard movement for an image I'm using for a game I'm trying to make. And yes I know there's a documentation page for it, but I'm having trouble figuring out the correct syntax to go about it.

Re: [racket-users] What is meant to be the public API of ‘drracket:rep:text<%>’ ?

I think the intention of the docs is that `drracket:rep:text<%>` is the interface for all of the methods listed under the `drracket:rep:text%` class. It looks like at the very least it extends the `racket:text<%>` interface, this is likely just an oversight in the documentation. Dan On Sun, Apr

Ok, for reference, in ‘share/pkgs/drracket/drracket/private/rep.rkt’ it extends: (class->interface text%) text:ports<%> editor:file<%> racket:text<%> color:text<%> Of the methods it adds to that, the ones not documented under ‘drracket:rep:text%’ are: copy-next-previous-expr

[racket-users] What is meant to be the public API of ‘drracket:rep:text<%>’ ?

The docs for ‘drracket:rep:text<%>’ just say it's an interface, without listing any interfaces it extends, nor methods it contains. Is there a public API it's meant to have and have documented? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
