[racket] running racket from the command line

[Matthew Johnson]

Dear List, 

I just downloaded the Racket binaries and installed them. I have been able to fire up DrRacket, however given that i prefer vim i was hoping to run racket from the command line. 

I've tried 

$ racket  and $ which racket

but the command is not found. Is there some linking step that i've missed? or is it not possible to run racket from the command line? 

thanks for your help

Ah, but where have you installed them?

I take it, then, that you're on a unix. On OS X for example, the relevant bin/ directory is located in the same directory as DrRacket.app, and so that's the directory (.../Racket\ v5.3.6/bin) that has to be (explicitly) added to your path. I don't know the layout of the various Linux distributions, but I imagine there's a broadly similar layout there.

Best wishes,

Norman

Thanks very much. Working well now.

For those that find this, a trap for young players is that you must
quote paths with spaces in them, else you will lose everything you
depend upon (even the command 'ls').

So it is

Export PATH="/Applications/Racket v5.3.6/bin":$PATH

Early on using Racket, like you I had some trouble or other quoting. I
adopted the perhaps dubious habit of, right after installing a new
version, renaming to e.g. /Applications/Racket_v5.3.6" -- i.e. " " ->
"_".

Thanks - good tip. I don't suppose there some awesome one liner that
does this for all working directory paths?

[Ryan Culpepper]

(for ([dir (map path->string (directory-list))])
(define newdir (string-replace dir " " "_"))
(unless (equal? dir newdir)
(rename-file-or-directory dir newdir #f)))

or

for dir in *; do
newdir=`echo "$dir" | tr " " _` ;
if [ "$dir" != "$newdir" ] ; then mv -i "$dir" "$newdir" ; fi ;
done

Feel free to delete newlines from either bit of code until it becomes a
one-liner :)
