[racket-users] typed/racket #:break #:guard
In doing some typed/racket, I have noticed some mismatch between observed behavior and the documentation at https://docs.racket-lang.org/ts-reference/special-forms.html 1) Documentation suggests that for/first and for/last should work, yet they seem to not type check. I've noticed sparse comments to that effect since 2014. 2) In working around for/first with for/fold, I discovered that #:break appears to function although the for loop documentation for typed racket (Section 2.3 in typed/racket reference) suggests that only the #:when guard is a keyword in the for/ family syntax. 3) In the struct documentation for typed racket, the many for syntax keywords shown do not include #:guard, yet it seems to work. Are #:break and #:guard correct to use in typed/racket or are they missing from the documentation intentionally?

[racket-users] Is it possible to cross-compile Racket?
Is it possible for example running DrRacket on Windows to generate standalone native executables for Mac OSX and some generic Linux distribution? -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

It should be possible from the command line, although there's a lot of room to improve the tooling. See http://docs.racket-lang.org/raco/cross-system.html?q=raco%20exe for the main hint. When you want to use your Windows installation and pretend that you're running on some target platform (e.g., to generate executables), you use racket -C -G ‹cross-dir›/etc -X ‹cross-dir›/collects -l- raco where ‹cross-dir› is an installation for the target platform. To get a ‹cross-dir›, unpack the corresponding "Minimal Racket" tarball from http://download.racket-lang.org/releases/6.11/ Most likely, you'll need some packages in that installation to use for your executable, so you'll set up the packages for a ‹cross-dir› with racket -C -G ‹cross-dir›/etc -X ‹cross-dir›/collects -l- raco pkg install When whatever packages your program uses are ready in ‹cross-dir›, then racket -C -G ‹cross-dir›/etc -X ‹cross-dir›/collects -l- raco exe racket -C -G ‹cross-dir›/etc -X ‹cross-dir›/collects -l- raco dist should work to produce an executable and then a distribution. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Is it possible to cross-compile Racket?
I've wondered this many times, and never investigated it. Thank you both for the question and answer.

[racket-users] Racket v6.12
Racket version 6.12 is now available from http://racket-lang.org/ * Changed the way some unsafe operations are exposed via `ffi/unsafe` libraries to help smooth a future transition to a new runtime system. * The `syntax-parse` form supports unwinding side-effects when it backtracks, both explicitly with `~undo` patterns and implicitly with the built-in managed state (using `syntax-parse-state-ref`, etc). * The `db` library supports SCRAM-SHA-256 authentication for backends running PostgreSQL 10 or later. Client support for SCRAM and other SASL mechanisms is provided by the new `sasl` library. * The `lazy-require-syntax` form supports lazy loading of macro transformers. Note that the macros must obey certain implementation constraints (see the `lazy-require-syntax` documentation). * Typed Racket no longer enforces types like (U String (Boxof String)) with the any/c contract. This fixes a type soundness issue, but may affect performance. Please submit a bug report if you find a program that runs significantly slower on v6.12 than earlier versions. * Typed Racket's type instantiation (`inst`) uses Any for omitted type arguments, allowing APIs to add additional type variables to functions without breaking existing programs. * `for/fold` users can customize the final result of a loop's computation using the `#:result` keyword. * The `--deps` option to `raco test` tests the packages the argument packages depends on, in addition to testing the packages themselves. For example, `raco test -p --deps pkg1 pkg2` tests all files from `pkg1`, `pkg2`, and all of their dependencies.

[racket-users] Building GUI launcher icons with raco setup
I have a Racket package that creates a GUI launcher using
gracket-launcher-names and gracket-launcher-libraries in the info.rkt file.
The package includes a module that programmatically generates the icons for
the GUI launcher at the expected paths ("my-application.png" and so forth).
I would like to have raco setup run this code before it builds the
launcher, but I haven't figured out how to get the code to run at the right
point.
I initially tried adding pre-install-collection to the info.rkt file, but
that is run before the collection is compiled, which means it doesn't work
if there is a .zo file that is out-of-date. I then tried using
install-collection, but that seems to be run after the launcher has been
created: it generates the icon files, but the launcher is created using the
default icon.
Is there a recommended way to do this? I guess I could have the install
function use install-gracket-program-launcher manually, instead of using
gracket-launcher-names and gracket-launcher-libraries, but that seems less
ideal.
