Re: [racket-users] Racket v7.8

2020-08-04 Thread 'John Clements' via Racket Users
Yes, there is documentation for this feature! Here are two ways to get it:

1) On a machine with 7.8 installed, run `raco docs prop:struct-field-info` at 
the command line, or (equivalently) highlight the word in drracket and hit F1. 
Both of these open a web browser window pointed at your local documentation 
installation.

2) Wait a few days for the 7.8 docs to be installed at docs.racket-lang.org.

Best,

John

[racket-users] Racket v7.8

2020-08-03 Thread 'John Clements' via Racket Users
Racket version 7.8 is now available from

https://racket-lang.org/


* Racket CS may become the default Racket implementation in the next
  release. With the improvements in this release, Racket CS provides all
  of the functionality of Racket BC (the current default
  implementation). If, between this release and the next, no bugs are
  discovered in Racket CS that are more serious than those typically
  discovered in Racket BC, then Racket CS will become the default for
  the next release.

* Racket CS supports AArch32 and AArch64, including places and
  futures. The implementation should be considered experimental in this
  initial release.

* Racket CS supports an "incremental" garbage-collection mode that can
  eliminate long GC pauses for some applications, such as animations and
  interactive games.

* Racket CS unboxes local floating-point arithmetic (like Racket BC).

* DrRacket's spell check features lower overhead and has fewer bugs.

* Web Server performance under high concurrency is [better by up to an
  order of magnitude](https://github.com/racket/web-server/pull/94/).
  The Web Server is also more resistant to clients attempting to use
  unconstrained resources.

* The math library includes the Kronecker product.

* Windows supports finer granularity for `sleep` when sleeping for short
  periods of time, improving performance in animation.

* The new prop:struct-field-info property provides static information
  about field names.

* Debugging context in Racket CS is limited to 64,000 frames
  (approximately the same as Racket BC). This reduces the time taken to
  handle out-of-memory failures.

* In `plot`, the legend font and the plot font can be controlled
  independently, and error-bars have an `#:invert?` option.

* The plot and math libraries have new maintainers: Alex Harsányi for
  plot and Pavel Pancheka and Jens Axel Søgaard for math.
