petit parser on gemstone?

Hi,
Does anybody knows if petit parser loads on Gemstone? I'm having a compile error trying to load it, and I think it is because of #==> selector (but I can't be sure)

thanks,
Esteban

I tried to port it awhile back myself and managed to get about as far as you have.

There is a port of smacc to Gemstone although if you are aware of this you might be trying to port petit parser to get away from smacc.

If the parser you are trying is build is simple enough you could do what we did and load tirade and subclass its parser.

Esteban,

I have not tried to port petit parser to GemStone... I think it is a worthwhile effort ... if you'd send me mail with configuration/load details for getting to the point where you are at right now, I could take a shot at loading it and scope out the porting effort ...

Hi Dale,
In fact, i didn't get too far... just tried loading ConfigurationOfPetitParser from http://source.lukas-renggli.ch/petit and then, executed this:

MCPlatformSupport commitOnAlmostOutOfMemoryDuring: [
        (ConfigurationOfPetitParser project version: #'stable') load: #('Core') ].

I first get a dependency error (missing BlockClosure), then proceed, then get the ==> error

cheers,
Esteban

On one hand I agree that it was a stupid decision to use #==> in the
first place (also GNU Smalltalk complained), but on the other hand
#==> is a totally valid binary selector according to ANSI Smalltalk.
Furthermore, there is already a significant amount of code that uses
#==> so it is kind of hard to change without breaking many grammars
:-)

Esteban,

GemStone _is_ having trouble with that selector, so I'm waiting to hear about status (never, soon, eventually)...

Esteban,

Unfortunately we won't have support for 3 character binary selectors until post GemStone 3.0 ...

Will not having #'==>' seriously affect your usage of PetitParser or can we fudge the problem for your purposes?

Hi Dale,
what we can do is a refactor of petit parser without #==>, and replace it by... for instance #mapTo:, and use that one... but that will be a fork, sadly :(

cheers,
Esteban

Yeah, it's not ideal, but until we can fix the parser in 3.1, it will be the only way:)

Ok, if you create "PortablePetitParser" on gemstone ss, and assign me as a developer (or better, rw rights to everybody), I will commit a first attempt (just a "rename method" refactor on ==> and >=>), and see what happens :)

Ah better name might be #transformWith: if it should be a keyword selector. There are two selectors btw.: ==> and >=>. In gnu smalltalk they used => and >< as selectors.

Consider using a binary selector, with a keyword selector you will get
a load of parenthesis in many cases :-)

yeah, I already fought with that. I was considering using ">>" and "<<" but if gnust is using => and ><, I can try to use the same... It likes me even less than my options, but well...

Don't know if the problem is related, but when I manually load PetitTests I get the following compile error:

'   false
 * ^1                                                                 *******
           ^ self parse: ''\x.\y.y''

1: [1026] invalid message pattern
'

so GemStone doesn't like use #false as a selector, either ... true is probably also disallowed ...

I am still digging ...

Well this is a new one ...

The UUID for ConfigurationOfPetitParser-EstebanLorenzano.17 and PetitTests-EstebanLorenzano.33 are both 'da390300-18a4-2802-80d7-0e00d0f65c1f'.

GemStone uses a MCDictionaryRepository as the cache repository which means that equality is used to compare keys ... since those two packages have the same UUID, PetitTests-EstebanLorenzano.33 is stored in the value of the association whose key is ConfigurationOfPetitParser-EstebanLorenzano.17 and is therefore effectively hidden when a lookup is done using the name of the versionInfo, instead of the UUID ...

So much for unique ID, huh?

Here's the tale of the tape from GemSource:

So it looks like if you do another commit of either ConfigurationOfPetitParser or PetitTests, then the UUID collision will go away ...

But wait, the same UUID is shared amongst several more packages!:
