Re: [Pharo-users] Maximum number of rules in PetitParser?

by Tudor Girba

One non-ideal solution is to split the parser into several classes inheriting from each other.

Hi, You should use announcements.

Maximum number of rules in PetitParser?

by James Foster

I have a grammar with about 600 rules. With some work Iâve come up with a useful subset of 400 rules. Unfortunately this is still more than the 255 number of instance variables that Pharo allows. Is there a way to have PetitParser use something other than instance variables to cache the rules? Especially something that works with PPBrowser? James

[ANN] FTP and WebDAV Plugins for Pharo's FileSystem

by Udo Schneider

All, I just finished FTP and WebDAV plugins for Pharo's FileSystem. This means you can now access remote FTP and WebDAV loactions with the exact same FileSystem API you are using to access local disks. The project lives on Smalltalk Hub: http://smalltalkhub.com/#!/~UdoSchneider/FileSystemNetwork Details in the project README or in a Blog entry: http://readthesourceluke.blogspot.de/2014/12/ftp-and-webdav-plugins-for-pha… Best Regards, Udo PS: Support for Netware & Rumpus FTP Servers as well as S3 support is next :-)

Could you provide the code snippet you use for building the finder browser?

I ask because given that it is single threaded, I wondered whether running multiple agents would present any sort of problem. Has anyone got experience of building something like this?

The cool thing is that you can read/understand all this threading code (ProcessorScheduler, Process, Semaphore, Monitor, Delay, ..). There few if any limits to the amount of processes you can have. To answer the second question: I believe SharedQueue is the class you should be looking at (first). Sven

Building agents in Pharo

by Andy Burnett

I am interested in building a system that uses co-operating agents to parse events. Is Pharo a suitable system for this? I ask because given that it is single threaded, I wondered whether running multiple agents would present any sort of problem. Has anyone got experience of building something like this? And, if so, what did you use for your basic queue? Is there a suitable FIFO style queue within Pharo? Cheers Andy
