Re: [racket-users] Non-ASCII characters stripped from input in macOS Terminal

[Jon Kleiser]

Thanks, Matthew! That was the final touch. I guess I will have to repeat 
that "ln -s" line after I upgrade Racket to the next version. Right?

Re: [racket-users] Non-ASCII characters stripped from input in macOS Terminal

[Matthew Flatt]

I forgot that Mac OS provides "/usr/lib/libreadline.dylib" as a symlink
to libedit, so installing readline via Homebrew doesn't (and shouldn't)
replace it.

To point Racket at your Homebrew-installred readline, go to the "lib"
directory adjacent to the "bin" directory that contains "racket", and
run

  ln -s /usr/local/opt/readline/lib/libreadline.dylib 

That way, Racket will find the "libreadline.dylib" from Homebrew
instead of the not-libreadline from the OS, since Racket looks in its
own "lib" first.

Re: [racket-users] Non-ASCII characters stripped from input in macOS Terminal

[Jon Kleiser]

Thanks for the info. However, there must be one detail I'm missing.
I have done "brew install readline", and "raco pkg install readline-gpl", 
and when I now do "raco pkg show", I get this:

Installation-wide:
 PackageChecksum Source
 main-distribution  34484fc4a83e3441...  catalog...tribution
 racket-lib 570306a2bfa6057f...  catalog racket-lib
 [198 auto-installed packages not shown]
User-specific for installation "7.0":
 Package   Checksum   Source
 readline-gpl  2990d5f3a3d43c2d2f...  catalog...eadline-gpl

However, when I do "racket", I still get 
"\U+FFC3\U+FFA6\U+FFC3\U+FFB8\U+FFC3\U+FFA5" when typing "æøå" at the 
prompt. Is there something I should (require ...)?

Seconded!  Racket-mode is excellent, and it grows more excellent over time.

[racket-users] Using racket with emacs

[tejaswi prakash]

Hello everyone,
I am new to racket and intend on using it for my projects.

I was wondering about how to use racket with emacs instead of using
drracket as that's a more familiar environment for me.

Any advice?
Thank you,
Tejaswi

Re: [racket-users] Non-ASCII characters stripped from input in macOS Terminal

[Matthew Flatt]

This is a problem with libedit, which Racket uses by default, and the
version of libedit that comes with Mac OS is not built with Unicode
support.

If you insteall readline (e.g., through Homebrew), then installing the
"readline-gpl" Racket package will use readline and support Unicode
input.

Re: [racket-users] Non-ASCII characters stripped from input in macOS Terminal

[Jon Kleiser]

My Terminal "Advanced" tab also says "Unicode (UTF-8)".
When I run the PicoLisp REPL, then I have no translation and stripping, 
"høy" is entered as "høy", it seems.

FWIW It is more a terminal problem than a Racket problem.
If I paste  høy  into the terminal, I see  h\U+FFC3\U+FFB8y.
My "Text Encoding" in the "Advanced" tab in the settings for terminal says
"Unicode (UTF-8)".

[racket-users] Where to start in DrRacket to support highlighting for Syntax Warnings?

[Tom Gillespie]

Hi all,
The language I'm developing has a strong use case for syntax warnings 
 for reporting cases of missing 
information (aka optional syntactic elements) to the user. I have done a 
first pass integration, and after reading Jack Firth's slides 
 (which end by suggesting 
DrRacket integration) I set out to complete the task. However after mucking 
about in the DrRacket source code for a while I have been unable to figure 
out the right place to hook in to provide DrRacket with the syntax location 
information (pretending that the warnings are errors for the purposes of 
display). Can someone point me in the right direction to get started? Many 
thanks!
Tom

[racket-users] Non-ASCII characters stripped from input in macOS Terminal

[Jon Kleiser]

If I enter this in the REPL in my macOS Terminal
(string->list "hei")
then I get '(#\h #\e #\i), as expected, but if I replace "hei" with "høy", 
the input line suddenly looks like this
(string->list "h\U+FFC3\U+FFB8y")
and what I get back is '(#\h #\y). The letter "ø" has been stripped away. 
The same happens with letters "æ" and "ø", typical Norwegian characters.
Is there something I can do to make the macOS Terminal REPL handle these 
Norwegian characters better?
In the DrRacket REPL this strange translation and stripping does not happen.

[racket-users] Re: Using ctags and vim with Racket

[Marc Kaufmann]

Thanks Alex, that was it. I thought I had tried it by setting .rkt to be 
interpreted as .scm, but I think that got overridden by vim-racket plugin. 
What I now did is:

ctags --language-force=scheme *.rkt
