[racket-dev] Problem with planet and Windows shortcuts

2014-09-17 Thread Antonio Menezes Leitao
Hi, Recent versions of Racket for Windows (at least, starting from 6.1.0.3) cannot install packages from planet when Racket's AppData/Roaming/ folder is a shortcut. I'm sure Racket could do it in previous versions. The output I get is: ..\..\Program

[racket-dev] Scribble bug?

2014-07-31 Thread Antonio Menezes Leitao
Hi, Scribble doesn't correctly render scaled bitmaps when the scale produces ratios in the width or height of the pict. The following scribble program: #lang scribble/base @(require pict) @(bitmap foo.jpg) generates an html file that includes: img style=vertical-align: 0px; margin: -3px -3px

[racket-dev] Problem with Values type constructor

2014-07-23 Thread Antonio Menezes Leitao
Hi, Although the typed racket documentation mentions Values as a type constructor, it does not work: Welcome to DrRacket, version 6.1.0.3--2014-07-18(e827817/a) [3m]. Language: typed/racket; memory limit: 1024 MB. (define (foo) : (Values Number Number) (values 1 2)) . Type Checker: parse error

Re: [racket-dev] proposal for moving to packages

2013-05-21 Thread Antonio Menezes Leitao
I've been using using Racket (and DrRacket) to teach programming to architecture students. These are not sophisticated users, so any move that makes it more difficult for them to use Racket is not good news. What happened to the batteries included motto? Just my 0.1 cents. Best, António.

Re: [racket-dev] Documentation problem

2012-06-25 Thread Antonio Menezes Leitao
Did you use `raco docs' to open the documentation page? No. All I did was to access the Help Desk from DrRacket's Help menu. BTW, this is a fresh install, after uninstalling the previous version. I can see the wrong links in the file index.html, in AppData/Roaming/Racket/5.3.0.11/doc/

[racket-dev] Hyperbolic functions

2012-06-25 Thread Antonio Menezes Leitao
Hi, Given that Racket implements the hyperbolic functions sinh, cosh, and tanh, I would like to suggest that it also provides the inverse functions asinh, acosh and atanh. For the moment, I'm living with my own definitions but it would be nicer if these were pre-defined. Best, Antonio.

[racket-dev] Documentation problem

2012-06-23 Thread Antonio Menezes Leitao
Hi, Recent nightly builds (e.g., for 5.3.0.10 or 5.3.0.11) install documentation files that incorrectly point to 5.3.0.4 files. This is visible after accessing the Help Desk: the page says it's for version 5.3.0.4 and clicking on any of the links will show the problem. Best, António.
