"mostly due to all the Objective-C/Foundation heritage".

Huh?

Objective-Smalltalk (http://objective.st) is also based on Objective-C/Foundation:

1. Hello World

    stdout println:'Hello World'.

in fact since it's an expression language, you can also just write

     'Hello World'.

(Might change the quotes to double quotes at some point).

2. Sending e-mail

Have to admit I haven't implemented the mailto scheme yet, but will be 1 line or close to it once it's in. Can probably get there

3. GET/POST

   page := http://objective.st

Save page to disk:

   file:objet-home.html := http://object.st

PUT

   http://objective.st/index.html := file:newHomePage.html

I haven't implemented POST yet, it interacts with a bunch of other features that are in the works.

4. Days between dates

Whatever you did with NSDate ...

5. JSON

The http and file URL scheme handlers have cooked versions that will figure out the MIME type and translate for you, but I haven't full figured out complex literal syntax yet.

6. Modern Datatypes

Actually, Swift has a big fail here for the single numeric type. Objective-Smalltalk currently just inherits to Objective-C stuff (so fail), but a real numeric tower is in other Smalltalks and both a goal and achievable in ObjST.

Why they didn't do this in Swift is puzzling.

7. Package distribution

ObjST has always been heavily framework based, for example 'framework:' is one of the supported URL schemes. Now that we have frameworks for iOS, it's time to start thinking about a "cooked" framework scheme that can do name mapping to URIs for the source of that framework etc.

8. HTTP server

This serves the directory passed as an argument:

   #!/usr/local/bin/stsh
   #-<void>fileserver:<ref>dir
   framework:ObjectiveHTTPD load.
   httpserver := (MPWSchemeHttpServer serverOnPort:8081).

   server := dir ⇨ (MPWCopyOnWriteScheme memoryCache) ⇨ httpserver.
   server start.

This will serve "Hello World" from an in-memory scheme-handler:

   #!/usr/local/bin/stsh
   framework:ObjectiveHTTPD load.
   scheme:site := MPWSiteMap scheme.
   server ← MPWSchemeHttpServer serverOnPort:8081
   site:/hi := 'Hello World!'.
   server start.
