Hi all,

Nicholas Riley has released F-Script Anywhere 1.1.1. This version 
includes many bug fixes, cleanups, and significantly reduces startup 
time. It also comes with a nice F-Script code snipet that lets you click 
on a view to examine it.

You can download it from http://web.sabi.net/nriley/software/#fsa

Phil.

Bob,

Thanks for the feedback.
The 1.2.2 version is now officially released (it is the same as the one you
already have).

As for HighLevelOOP.pdf, it is not included by mistake... (Still available
directly from the web site).
EmbeddingFScriptIntoCocoa.pdf was not in the previous version (actually, it
is not released yet), but I have probably sent it to you in a private e-mail
(or else, you have entered the twilight zone :-)
By the way, I still hope to see it published by O'Reilly soon.

Best,

Phil

PS: Are some of you on the list planning to come to ESUG 2002 this summer?

Bill,

Thank you for the report. It prompted the discovery of two very serious bugs
in the Block archiving support. The first one prevents correct un-archiving
of a block with cascade message. The exact nature and scope of the other bug
is under investigation at this time (read: I'm not going to sleep a lot this
night). Those bugs will be corrected in the next version and a source code
patch will be available before that.

You should also note that the way you archive the block in your example is
not correct. FSUnarchiver is a private class that should not be used; only
the F-Script run-time know how to use it. The correct way to save and load
objects from F-Script is using the save: and load: methods (cf. section 9 of
the guide). So in your example, you would do:

> converter save:'/tmp/converter.fsobj'

> cvt := sys load:'/tmp/converter.fsobj'

Best,

Phil

note that the line above is where the error occurs.
that's your clue. it works in FScript, but not on unarchiving.
i would guess that it isn't archiving the item within? and storing off a 
value that isn't valid on unarchiving.
but then again... it the inspector is showing me the actual text that it 
is failing on, not some pointer thingy.
so, i don't know what.
post the answer if you figure it out.
i have only made half-way through the guide, so i am 1/2 past a total 
beginner.
fun stuff. almost no activity on this list. although i did get responses 
when i posted questions. from Philippe.
if you don't get an answer you could try emailing him directly. i got a 
response that way the first time i had a problem. actually, i note that 
you answered my first question on this list. hello, again.

Trying to archive the converter from "Scripting Cocoa with F-Script" I 
encountered the following:

 > FSArchiver archiveRootObject: converter toFile: '/tmp/converter.fsobj'
true

 > cvt := FSUnarchiver unarchiveObjectWithFile: '/tmp/converter.fsobj'

Uncaught system exception: signal 10

This may have something to do with message patterns, as avoiding them 
seems to avoid the problem.

Paste the following into F-Script.app to reproduce:

converter := [:title | |window conversionScript form button line|
   window := NSWindow alloc initWithContentRect:(125<>513 extent:400<>200)
                      styleMask:NSTitledWindowMask + NSClosableWindowMask
                                + NSMiniaturizableWindowMask + 
NSResizableWindowMask
                      backing:NSBackingStoreBuffered
                      defer:NO.

   conversionScript := [(form cellAtIndex:2) setStringValue:(form 
cellAtIndex:0)
   floatValue * (form cellAtIndex:1) floatValue. form selectTextAtIndex:0].

   form := (NSForm alloc initWithFrame:(60<>90 extent:320<>85)) autorelease.
   form addEntry:@{'Exchange Rate per $1', 'Dollars to Convert', 'Amount in 
Other Currency'}.
   form setAutosizesCells:YES; setTarget:conversionScript; setAction:#value.

   button := (NSButton alloc initWithFrame:(250<>20 extent:90<>30)) 
autorelease.
   button setBezelStyle:NSRoundedBezelStyle; setTitle:'Convert';
setTarget:conversionScript; setAction:#value.

   line := (NSBox alloc initWithFrame:(15<>70 extent:370<>2)) autorelease.

   window contentView addSubview:@{form, button, line}.
   window setTitle:title; orderFront:nil.
].
FSArchiver archiveRootObject: converter toFile: '/tmp/converter.fsobj'.
cvt := FSUnarchiver unarchiveObjectWithFile: '/tmp/converter.fsobj'.
cvt value: 'moo'.

It is possible to output things on stdout using Cocoa APIs (since, stdout is
a UNIX file, you can use the Cocoa file I/O APIs).

It is also possible to launch "system commands" from F-Script; Again, you
can use standard Cocoa APIs from F-Script to do that. You can also look at
the FSTask class that comes with F-Script (this class is not documented but
you can figure how it works by looking at source code and the example in the
header file).

While not completely trivial, it would not be too hard to write a standard
UNIX command line tool version of F-Script: a tool that would read its
instructions on stdin and produces some output on stdout. But as it stands,
it would be far to offer the convenience of Perl to deal with files, systems
commands and so on. We would need to add an easy notation to cretate
  "files" objects and a high-level and well integrated way to deal with
"system commands" and to generate output to stdout.

Best,

Phil

i notice that if i have a syntax error in a script, it gets printed out in 
the terminal session where i ran the script.
so might it be possible to directly output a string from a script to the 
terminal via stdout, say?
a longer shot would be to get command line arguments when running a script.
that would make fscripter a fully functional command line tool.
well, maybe not fully functional - would need a way to execute system 
commands from an script and retrieve results from stdin.
thinking of it as high power perl with system level access on one side, 
and Cocoa access on the other, with FScript as the language in the middle.
is any of this even feasible -  as feature requests?

very good. i am learning - slowly. thank you.
by the way, what does the 'F' in 'F-Script' stand for?

i wish success to FScript.

Note that "#airplane" is just a compact notation equivalent to the following
block literal: [:arg| arg airplane].
Actually, you are not restricted to use the compact notation for blocks when
invoking "inspectWith:", or any other method requiring blocks as arguments.
Thus, you can express arbitrarily complex expression in your blocks...

So what you want is:

F inspectWith:{#ident, [:aFlight | aFlight airplane location]}

Hi Bob,

You can't really make an alias for a message send using F-Script. However,
what you can do to avoid retyping a lengthy sequence of code is to factorize
it in a block. For instance, here is a block that will send your specific
"inspectWith:" message to the provided argument.

ins := [:inpectedObject | inspectedObject inspectWith:{#name, #address,
#salary}]

You can then execute the block by sending it a "value" message and providing
the required argument. For example:

ins value:(P at:P address = 'PARIS')

Phil

Hash: SHA1

Bob,

you're right, I can reproduce the error now. Seems like this bug has 
been obscured by my test setup. I don't know how the fscripter path can 
be relevant after its successful start. Maybe the NSNotification center 
somehow uses the program's path to deliver notifications (judging from 
the error message the notification delivery is where the problem occurs) 
and the startup path is different than the one in the shebang line.

I don't know when I will have time to look at this... If you can live 
with it, so can I :-)

Cheers,
Sven

Hi Bob,

> is there a concept of a subroutine in F-Script? so a full app could be
created?

F-Script blocks allow you to write F-Script "subroutines". Blocks can takes
parameters and return a result, they have local variables, and also a few
more interesting capacities (see "bBock closure" in the Smalltalk
literature).

Blocks can be invoked from F-Script code, and also from Objective-C. In
addition, F-Script comes as a framework you can link with your own
applications. This makes it relatively easy to build an "Objective-C" app
for which most of the code is in fact written in F-Script.

F-Script gives you the option of accessing the scripting engine
programmatically. See the FSInterpreter class documentation.

Best,

Phil

oh. if i run my script in same directory as the fscripter file, it works.
i had fscripter in a different directory than my script with a full path 
in the shebang line.
now it works with first line as:   #! fscripter
which is how examples are written.
so i guess it has always been this way?
i can live with it this way.

has anyone tried fscripter with FScript-1.2.1? I get an error when i run 
it trying to create a window:
2002-04-26 21:16:37.267 fscripter[476] looking for fsMenuHandler...

_sendFinishLaunchingNotification

author of fscripter suggests it may not work with FScript 1.2.1.

is there a concept of a subroutine in F-Script? so a full app could be 
created?
or is it meant to be included in a 'real' app using C or Java and called 
from there?
but it is interactive, so how used from an app that feeds it input and 
gets output from it?
i feel like i don't get it :)-:(.

What if....

F-Script's object browser could be implemented on some sort of
iPod type device with a jog wheel.  When the user needs to input
text or numbers there's have to be some sort of letter-number "spinner"
which might be problematic...  but I think a lot could be done with
an object browser and a jog wheel...

anyway, it's fun to daydream about an f-script PDA....
