Patch for gnu readline support library and input port. #252

Open hyln9 opened 10 years ago

hyln9 commented 10 years ago

I've decided to work on a readline library for ikarus. Why, because I love Ikarus :), but I hate the default REPL :(.

Attached is a basic implementation. There are some issues with filling the port string buffer, but I should have that fixed shortly.

I'm not sure how to (import ikarus.string) to get access to string-copy! so I created a softlink: ln -s ../../scheme/ikarus.string.ss lib/ikarus/string.ss . Anybody know the correct way to import definitions from the ikarus.*.ss files under scheme/?

I get a segmentation fault upon CTRL-D, probably due to C readline() returning a NULL. I don't think the 'char* return type correctly coerces NULL to #f.

Can anybody recommend a place to host bzr repos?

BTW: This patch works under Ubuntu. I didn't bother with Cygwin or OS X.

JTMI, you can use rlwrap. See this thread: http://groups.google.com/group/ikarus-users/browse_thread/thread/2cc1f989b218e4c2

Or my "inferior Scheme" Emacs mode (which is a lot better than readline): https://code.launchpad.net/~derick-eddington/scheme-mode/derick-.emacs.d

string-copy! is exported from the (ikarus) library.

so I created a softlink: ln -s ../../scheme/ikarus.string.ss lib/ikarus/string.ss . Anybody know the correct way to import definitions from the ikarus.*.ss files under scheme/?

If they're not exported from the (ikarus) library, it's intentional, because they're not intended to be public. You can do:

(list-sort (lambda (a b) (string<? (symbol->string a) (symbol->string b))) (environment-symbols (environment '(ikarus))))

to get a (sorted) list of all the exports from (ikarus) (which is a superset of the standard R6RS (rnrs) library). You can also look at the definition of identifier->library-map in ikarus.dev/scheme/makefile.ss .

Can anybody recommend a place to host bzr repos?

Yes: launchpad.net . I recommend following the "Read the guide" link. Also look at https://launchpad.net/ikarus-libraries to see how some of us (including me) have been using LaunchPad.
