[Larceny-users] apropos for Larceny

[KenD]

Greetings,

As an occasional Scheme user, I forget the details and find an "apropos" function useful.

(apropos "foo")

will look in Larceny's interaction-environment and return a list of variable-name symbols which contain a match to "foo".

e.g.

(import (scheme load))
(load "apropos.scm")
(apropos "conso")

(console-error-port
console-error-port-factory
console-input-port
console-input-port-factory
console-output-port
console-output-port-factory)

PS: Sorry about the legal boiler plate.
If you (re)distribute, feel free to substitute any open source licence you are currently using.

There's also an apropos function already. Try (require 'apropos) to load
it.

Thanks. I missed that.

Er, how does one import that with/into -r7rs mode?

Thanks,

(import (primitives apropos)) ; could have been done by earlier import
(apropos "conso")

(console-error-port
console-error-port-factory
console-input-port
console-input-port-factory
console-output-port
console-output-port-factory)


This does not find macros, which use a different mechanism.

Ah! Much better!!!

I had tried IMPORT and REQUIRE separately in different sessions.

Requiring both forms is not intuitive.

I guess I really need to find time to read more of the documentation.

Oh, and I just found the larceny/lib directory BTW. Much goodness.

I have habitually cd'd to larceny/src to start searches and did not find apropos in larceny/src/{Lib,Rts,*}.

Thanks for bearing with me. I really am slow about such things. At this point you have to consider me a "programming hobbyist"

Cheers,
