Figure out the best way to add rlwrap/jline support for REPLs about lein-cljsbuild HOT 8 CLOSED

I looked at Leiningen's rlwrap support, and extracted the basic rlwrap options. The following command will launch a ClojureScript REPL with good readline settings:

rlwrap -r -m -q '\"' -b "(){}[],^%3@\";:'" lein trampoline cljsbuild <repl-command>

from lein-cljsbuild.

This should be added to the documentation somewhere, perhaps the wiki.

from lein-cljsbuild.

So the above command doesn't quite work on Mac OS with rlwrap installed via homebrew; the error message is:

rlwrap: warning: on this system, the getopt() library function doesn't
grok optional arguments, so '-q' is taken as an argument to the -m option
Is this what you meant? If not, please provide an argument
rlwrap: Cannot execute ": No such file or directory

This seems to be related to an issue that was reported last year in Leiningen:

http://groups.google.com/group/leiningen/browse_thread/thread/a55dde87fe489c5b

and fixed with this commit:

technomancy/leiningen@ab6293d

from lein-cljsbuild.

That's the bad news. The good news is that omitting -q seems to work; v.i.z:

rlwrap -r -m '"' -b "(){}[],^%3@";:'" lein trampoline cljsbuild repl-listen

from lein-cljsbuild.

To avoid the long command, the bash script (I called it runj):

#!/bin/bash
rlwrap -r -m '"' -b "(){}[],^%3@";:'" lein trampoline cljsbuild $1

from lein-cljsbuild.

I added a wiki page to document this: https://github.com/emezeske/lein-cljsbuild/wiki/Using-Readline-with-REPLs-for-Better-Editing .

from lein-cljsbuild.

I just added a line about omitting -q on Mac OS, hope this is OK-----

Thanks,

Nick.
