NativeBoost installation woes with Mac OS X

LawsonEnglish
 
Hi. On an Intel Mac running Mac OS X 10.6.8, I followed the instructions
to install a NativeBoost VM found here:
http://code.google.com/p/nativeboost/wiki/Installation. I downloaded the
latest Mac NBCog VM,  and ran into an error after evaluating NBInstaller
install.

I'm using the 4.3alpha-11636.image file. The 4.2 image gives a different
set of errors but also wont install:

The progress bar window says: Compiling NativeBoost-Core-IgorStasenko.36


The window title is "Syntax error" with a split text field. The top
field contains:
nbExternalStructure Fields parsing spec parseFields:byte


The bottom field has a red error message embedded in this line:

         stream peek == #Invalid literal character ->; ifTrue: [ stream
next ].
     ].



Help?

I didn't tested an installation in squeak 4.2 images.
It looks like there is a change in parser which don't likes the
following syntax:

#( a; b ; c)


imo, this is correct syntax. a ';' should be converted to #; symbol.

Squeak 3.6:
#( a; b ; c) ==> #(#a #; #b #; #c)

Squeak 3.8:
#( a; b ; c) ==> #(#a #; #b #; #c)

Squeak trunk:
#( a; b ; c) ==> #(#a #';' #b #';' #c)

PharoCore-1.3-13173:
#( a; b ; c) ==> #(#a #';' #b #';' #c)

ok, then problem is in something else.
Lawson, could you please paste the full method source with problematic code?

This is what appeared in the Syntax Error window:


parseFields: fieldSpec byteAlignment: byteAlign structure: structClass

     | stream type name gen |
     stream := fieldSpec readStream.
     gen := NBFFICallout new requestor: structClass.

     fields := Dictionary new.
     totalSize := 0.
     [ stream atEnd ] whileFalse: [
         type := gen resolveType: stream next.
         name := stream next.
         name isSymbol ifFalse: [ self error: 'invalid field name'].
         fields at: name ifPresent: [ self error: 'duplicate field name' ].
         fields at: name put: { type. totalSize }.

         totalSize := totalSize + type storageSize.
         totalSize \\ byteAlign > 0 ifTrue: [ totalSize := totalSize \\
byteAlign + byteAlign ].

         stream peek == #Invalid literal character ->; ifTrue: [ stream
next ].
     ].

#; inspect -> Syntax error though...

ps.
stream peek == #;

sure it's not a typo and should be
stream peek == $;  ?

yes its not a typo. Since it is a stream from given array:

#( a ; b ; c ; ) readStream

stream peek at some moment could answer #; symbol.

perhaps i should write it like #';' ?
but why it considered invalid?

Ah, all these behaviours were removed from Squeak
#; -> #';'
#1 -> 1
#$1 -> $1
The rationale was:
1) These were not defined in st80, nor in any formal Smalltalk syntax.
# was only for literal symbols or literal arrays.
2) #';' 1 and $1 already are literals, so we don't need any other
syntax or additional decoration.
3) This is not portable, no other dialect would accept it.
4) And there were plenty of oddities with doubled # or spaces inserted
in between...

Now, Igor you seem to suggest that these extensions would be logical
given how the inside of literal array is interpreted, is that it?

No, i'm not suggesting that. :)

But as you noted, i agree that if array literals treating ';' inside
as a #; literal, then it would be more consistent to allow #; syntax
as well.

Anyways, it is easy to change the method to be correct even for more
strict syntax rules.

I see. Some kind of least surprise principle...
But adding this syntax would immediately displace the problem one
character further...
...and I'm not very sure how universal would the interpretation of
multi non character symbols be:
#(+/|!?&%,;;<>_.:=--^:*)
->
 #(#+/ #| #!?&%, #';' #';' #<> #'_' #'.' #':=' #-- #'^' #':' #*)

The delimitation seems arbitrary and hard to explain...
how | is distinguished from other binary selectors...
how := is handled specially ...
To me, it's better to leave those behaviour as unspecified and reserve
the right to perform additional cleanup later

Re: NativeBoost installation woes with Mac OS X

In reply to this post by Igor Stasenko
 
I have a new sad thing to report: NativeBoost simply crashes squeak when
I use a 4.1 image. I suspect this means that it loaded completely and
then did something that Snow Leopard -Mac OS X 10.6.8- doesn't like,
because it is fully 64-bit. I havent' tested it on Lion (10.7) but I
suspect the same thing will happen.
