Thread: [Jscheme-user] quasi string?

I'm wondering if we could add a couple of check to not add empty strings.

Hello Schemers,

I have a patch, if anyone is interested, that lets you use the GNU
'readline' library for interactive expression editing in the REPL; it
also supports S-expression history.

Let me know if you're interested.

This is a C library right, what does it let you do.

It gives you all the nice features like history with up arrow/down arrow
access, tab completion (I think), basically everything you get with a
mysql console, or python interactive mode, or bash. I understand that
Jython uses Java-Readline http://java-readline.sourceforge.net/, which
just JNI-wrappers the C library.

It's definitely very nice and would make the jscheme interpreter act
more like most commandline driven Linux tools.

Unfortunately, GNU readline is GPL licensed (as you might imagine). My
understanding is that there is a BSD licensed replacement
(http://sourceforge.net/projects/libedit/), but I don't know how active
or useful it is, and I don't know how well it works with Java-readline
(which itself is LGPL).=20

Rusty was just cautioning me about adding any GPL software to JScheme.
Alan, can you use java-readline?

Also Tim is working on a scheme where we can contribute examples of using JScheme which include components under various licences.

I know there's been discussion about readline on the Guile mailing list.  Greg, can you comment on it?

BTW, i run JScheme in Emacs to be safe, so i don't need to add these features through another mechanism.  Am i just old, or what?
