[racket-users] Re: Running from command line and staying in REPL?
I have found some info here: https://docs.racket-lang.org/guide/racket.html#%28part._start-interactive-mode%29 However, I haven't reached my goal yet. If I do this racket -t hello.rkt -i then my hello.rkt is executed, and I end with a ">" prompt, but trying a command like (exit) at that point is not very successful, as you can see here: $ racket -t hello.rkt -i Welcome to Racket v7.0.

[racket-users] Running from command line and staying in REPL?
Hi, I would like to run some Racket programs in the macOS Terminal (racket foo.rkt bar1 bar2), and keep staying in the Racket REPL when my code has completed. Is that possible? /Jon -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Running from command line and staying in REPL?
Works like a charm. Thanks!

Re: [racket-users] Running from command line and staying in REPL?
Sorry, but I'm not quite happy yet. ;-) When I get the ">" prompt, the definitions made in my hello.rkt seems to be gone. I get "cannot reference an identifier before its definition". How can I avoid that definitions and data get lost? torsdag 13. september 2018 13.03.42 UTC+2 skrev Jon Kleiser følgende: > > Works like a charm.

I think I found the answer: Use (provide . . .). torsdag 13. september 2018 13.16.15 UTC+2 skrev Jon Kleiser følgende: > > Sorry, but I'm not quite happy yet. ;-) > When I get the ">" prompt, the definitions made in my hello.rkt seems to > be gone.

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

[racket-users] Non-ASCII characters stripped from input in macOS Terminal
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. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Non-ASCII characters stripped from input in macOS Terminal
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. fredag 14. september 2018 10.55.28 UTC+2 skrev Jens Axel Søgaard følgende: > > > Den fre. 14. sep. 2018 kl. 10.28 skrev 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).

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