Parsing some Java in VW
Locked
 
|
Dear List,
I wish to parse some Java in VW using SmaCC, but where can I find a proper grammar? The SmaCC parcel does not seem to include one, and google was not that successful this time. I am therefore using the Java Grammar that is included in the Squeak SmaCC distribution. Works fine, expect for multilines comments. The scanner definition ends with -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= <eol>: \r | \n | \r\n ; <whitespace>: \s+ ; <comment>: \/\/ [^\r\n]* <eol> ; <multipleLineComment>: \/ \* ; -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Maybe it has to be adjusted for VW since it works fine for Squeak. Am I missing something obvious? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. |

Scanner definition:
<multipleLineComment>: \/ \* ;" and the following scanner method: multipleLineComment | char | [[(char := stream next) isNil or: [char == $*]] whileFalse. stream atEnd ifTrue: [self scannerError]. stream peekFor: $/] whileFalse. ^ self whitespace |

I haven't looked at SmaCC for Squeak, but what is wrong with the SmaCC
Java parser in the examples parcel? Seems to work fine with multi-line comments. You can find it in the Contributed/SmaCC directory (using Directories tab in the Parcel Manager tool). - Dave -----Original Message----- From: Bergel, Alexandre [mailto:[hidden email]] Sent: Saturday, December 08, 2007 1:03 PM To: VWNC Subject: Parsing some Java in VW Dear List, I wish to parse some Java in VW using SmaCC, but where can I find a proper grammar?

I did not know this package existed.
This package is for Java 1.2. do you know whether a java 1.5 is around ? I wish to parse generic- aware code...

1.5 sounds significantly different. Were you saying that the Java 1.5
parser is available in Squeak? If not, maybe someone on the list can help. - Dave -----Original Message----- From: Bergel, Alexandre [mailto:[hidden email]] Sent: Monday, December 10, 2007 5:33 PM To: Wallen, David Cc: VWNC Subject: Re: Parsing some Java in VW I did not know this package existed.

It seems to be the same java parser in VW and Squeak for Java 1.2.
So, nobody has a grammar that parses Java 1.5? If I do not have any positive answer in a couple of days, I will work on it...

Why don't you just reuse parsers existing for java to output MSE which
you -then- load into smalltalk? Why going through the trouble of redoing it fully in smalltalk?
