I would love also to see a 6.1 standalone download for windows 64 bit, apparently the other platforms have 64 bit downloads. Is there a reason why its not available for Windows ?

Installing SmaCC

by Dimitris Chloupis

Hey guys I downloaded the latest Pharo 6.1 64bit for Windows and tried to install SmaCC through the catalog browser but it failed I did manage to install it following the instruction in the github repo but I see that I am missing most parser packages. The languages I am interested are Smalltalk (which is included) and C (if possible C++ too) cause I will be creating a new language which will be a cross between C and Smalltalk (very similar to smalltalk syntax but with the addtion of C types and no GC and dynamic typing and also a partial implementation of OOP that is quite diffirent). My goal is compilation of my language to readable C code so the ability to parse also existing C code is needed. Any help is greatly appreciated , thanks :)

Yes, it will not happen.

Re: [Pharo-users] TxText ?

by Peter Uhnak

I think it is "going to be replaced" for several years now, so I wouldn't worry about it too much.

TxText ?

by Hilaire

Hi, I read on some Rubric class comment, it will be replaced or merged with TxText. I heard about TxText on this list, but what is the status of TxText? Thanks Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] [vwnc] Parsing in Smalltalk

by Jan KurÅ¡

HI Steffen, Thanks for the report, number pleases me :) Speaking of tool for porting, I was recently showed this one, I don't have any experience with it: https://github.com/ObjectProfile/Pharo2VW Speaking of character ranges, there is currently available: #letter asPParser (to recognize character matching #isLetter predicate) #word asPParser (characters matching #isAlphaNumeric predicate) #digit (#isDigit predicate) #hex ([a-fA-F]) #space #blank #any You can find definitions in PP2NodeFactory, see implementation of #hex, which is probably closest to what you want. For your convenience, your project can extend the class to fit your needs. You can also specify:$a asPParser / $b asPParser / $c asPParser / #digit asPParser ... PetitParser2 can recognize this pattern and makes a character class during optimization pass.
