Subject: [slang-users] slirp 1.7.9 released
Message-ID: <20060303195336.GA15212@svoboda.mit.edu>

Friends,

Version 1.7.9 of SLIRP has been released to

     http://space.mit.edu/CXC/software/slang/modules/slirp

This is a very minor release, issued primarily to establish
portability to Windows, under MingW and CygWin.

Regards,
Mike Noble

-----------------------------------------------------------------------

Changes in v1.7.9
 1.	Ensure SLSH -n switch is used in all examples, and generated makefiles
 2.	slirp_debug_pause() no longer included by default in generated
	modules; use new -d option to force its inclusion
 3.	Established Windows portability, under MinGW 5.0.2 (gcc 3.4.2)
	and CygWin 1.5.18 (gcc 3.3.3)

	** Requires as-yet unreleased patches to S-Lang 2.0.6 ***

	NOTE FOR CYGWIN 1.5.19 USERS: there appears to be a buggy
	interaction between CygWin 1.5.19 and GCC 3.4.4, which can
	cause the host application to abort when loading C++ DLLs.
	(example: www.cygwin.com/ml/cygwin/2005-08/msg00061.html)
	This causes the SLIRP C++ regression tests to fail, and
	effectively prevents the use of SLIRP-generated C++ modules.

Message-ID: <440D91A6.7070701@head.cfa.harvard.edu>

I am using slang2 and here is the issue that I encountered
Consider sample code :

variable x = [1:100:1];
newvar = @variable;
is_defined("newvar");

is_defined returns 0 which means newvar is not defined.
But I can do print(newvar) and I get valid values;
What am I missing?

thanks,
RobertM

It is unclear to me how this would even work.  "variable" is
a reserved identifier, and so cannot be used in this context.

	slsh> variable x = [1:100:1];
	slsh> newvar = @variable;
	<stdin>:2: Expecting a PRIMARY: found 'variable'
	<stdin>:2:<top-level>:Syntax Error

After which

	slsh> is_defined("newvar");

returns 

	0

as expected.  What application/version are you trying this within?

HTH,
Mike

Sorry for the confusion I made small typo.
The code should be :

variable x = [1:100:1];
newvar = @x;
is_defined("newvar");

Then I believe this is a namespace issue.

	slsh> implements("foo")
	slsh> x = [1:100]
	slsh> newvar = @x
	slsh> is_defined("foo->newvar")
	-2
	slsh> is_defined("newvar")
	0

The print() works because it operates in the current namespace,
which in slsh for example, is by default unnamed.

HTH,

Right.  Unless a namespace prefix is specified, `is_defined` searches
the "Global" namespace.  Variables that are automatically declared are
placed in the static namespace, which may be anonymous as in your
case.  The `is_defined` function will not search such namespaces.  If
you want to search the current namespace, which may be an
anonymous one, then use the `_apropos` function, e.g.,

   names = _apropos (current_namespace (), "^newvar$", 0xFF);

Also you might consider using __get_reference:

   if (NULL != __get_reference ("newvar"))
     {
       % newvar is defined
         .
	 .
     }

Thanks,

Subject: [slang-users] slcurses
Message-ID: <753f6a4a0603140623k684846edm1aecec866cf4936d@mail.gmail.com>

After installing s-lang I noticed an slcurses.h file in my include
folder. It looks like the intention was to implement an s-lang version
of the nCurses interface (functions, defines, etc). I tried linking
-lslang and using the function in slcurses.h but had no luck.

Is this still a work in progress?

I'm interested because it's always nice to have alternatives. Are
there any other viable alternatives to nCurses that you are aware of?

The reason slcurses.h and slcurses.c exist is that it allowed me to
use a number of curses-based test programs during the development of
the SLsmg routines.  It is not fully compatible with curses and as
such, I do not recommend the use of slcurses.  Stick with the SLsmg
routines.

>Is this still a work in progress?

No, but it is still maintained.

curses? pdcurses?

What exactly are you looking at to do ?

I have developed a System using Slang and C routines to give
full Stack Based menuing, Window Boxes, Pop-up's, Quick Functions,
callback and a host of other goodies.

It is to be used to develop "Business" applications in S-Lang.

It is on hold, while I develop a B+-Tree based database engine
native for S-lang.

Any of the above sound like what you need ?

Hi,

slsh> 0; ++(); message(string());
0

Is the pre- or post-increment/decrement operator usable with values on
the stack? If not, the above code should raise an exception.

Bye, J?rg.

Subject: [slang-users] String HASH function
Message-ID: <442D5E91.60100@versaccounting.com>

I have decided my SLAGS's MVISAM will have the B+tree key's stored
as 64 BIT hash function keys. The data will still be regular data
it's just the B+TREE node key info will be some sort of a hashed
value.

Now, I need something that will produce fairly linear results.
i.e.:

Apples
Apples and oranges
Apple Suauce
Another Long Line of Description ...

.... and so on and so ..

will produce results that can be used as so when you start
using a secondary key, the results will be in alphabetical order.

Any suggestions and or pointers on this one?

Thanks ...
