Advanced Interactive Shell

Hello Group,
I'm looking for a somewhat advanced scheme shell (something like
ipython for python, but, well for scheme).

Features that I'd appreciate:

* gnu readline line editing
* visual parentheses matching (like the vim standard-plugin MatchParen
does)
* <tab> syntax completion

One solution that provides line editing is to pipe through ledit, but
then you do not have parentheses matching. DrScheme comes with
parentheses matching, but without line editing (and you can't use it
without X). I did not find any syntax completion, but this has lowest
priority (for me;).

Is there anything around?

Thx;)

I have once written a tiny editor that provides paren highlighting, go
to matching paren, and expression evaluation in an interactive buffer.
Having said that, it is hardly maintained, has a Wordstar-like interface
and requires T3X to compile. If you are interested anyways:

I just discovered that Guile with readline support does exactly what I
want:

Gambit has all of that and it highlights the input in bold to
distinguish it from the output in plain text.

I would advise:

_\| |/_
_ emacs _
/| |\

This is a nice lisp shell in general. It has even better than
readline editing. It has a very nice paredit mode to edit
parenthesized code. It also has TAB completion. And it works as well
in a terminal as in X (or other native GUIs).

Having put (setq inferior-lisp-program "/usr/bin/mzscheme") in ~/.emacs

you would launch your scheme shell with:

emacs -f inferior-lisp

Have a look at:

I usually wrap rlwrap (take a recent wersions, old ones don't work
properly) around mzscheme, that works.

MzScheme had readline support some time ago, but it is no longer linked
against readline due to license mismatches.
