After I'm not sure that you need agents running all the time (reacting to each characters you type). I would be you I would - prototype a hierarchy of classes whose instances have a kind of patterns to know if they should be kick in - at the end of each line, I would send the line to a list of such "agent" and react - then only then, I would consider to fork the behavior of the agents. why? because when you can avoid concurrency this is simpler :) > > Cheers > Andy >

Simple Examples: 1. If I enter a web address it could look it up on Delicious.com and extract links that had been similarly tagged. 2. If I enter something that looks like a name, it would search google scholar, or mendeley and include links to any documents 3. If I entered "call david tomorrow" it would be able to add something to my things to do list. My - very early - thoughts are that I need to continually parse the text, as I type, and various agents would look for the things they are interested in. The question is how best to model this, and process the data. Cheers Andy

Christmas gift: Memory Monitor

by Alexandre Bergel

Hi! Torsten motivated us to upgrade Memory monitor. Here is the script: -=-=-=-=-=-=-=-=-=-=-=-= Gofer it smalltalkhubUser: 'abergel' project: 'MemoryMonitor'; configurationOf: 'MemoryMonitor'; loadStable. -=-=-=-=-=-=-=-=-=-=-=-= In Pharo 3.0, you get something like: In Pharo 4.0, buttons are missing. Any idea whatâs wrong? Memory monitor is accessible from the configuration browser.

Re: [Pharo-users] Question regarding crashes using OpenDBXDriver

by Guillermo Polito

Hi Michael, Can you share with us how did you download the OpenDBX package in Pharo, and the OpenDBX and Mysql libraries (and each of their versions). >From the dump you share I can only notice that the problem is when calling OpenDBX finalize because of an error, and that it is the first time that you're calling that method because NativeBoost just generated the native code on that stack trace. However, I cannot know if that is because there are any problems on the DBX Pharo side (wrong arguments sent to finalize) or in the library side... Also, which is the query that you're sending to the database? :) Guille On Sun, Dec 21, 2014 at 9:25 AM, stepharo <stepharo(a)free.fr> wrote: > Hello michael > > I do not have experience with db but this is on our roadmap. > Olivier Auverlot started an analysis of the different solutions offered in > Pharo. > > https://docs.google.com/spreadsheets/d/1uD6UFmwCJxAkOC9tlvdJsHtt10C0KHJ6Zp8… > > Check the joint documents > > Le 18/12/14 15:57, Michael Berg a Ã©crit : > > Hello, > > > > Iâm usually just reading the list (and Pharo-dev), but right now Iâm > trying to figure out, if I could use Pharo with Seaside to implement a > little REST Interface for some MySQL database Iâm using.

Re: [Pharo-users] Building agents in Pharo

by Andy Burnett

Sven wrote << The standard VM is using a single OS process (and thus uses a single core) but manages its own user land threads called Processes. 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). >> Great, that sounds very encouraging. Thanks very much. Andy

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

by Udo Schneider

James, can you split the grammar into logical subgrammars? If yes PetitParser's "dependent grammars" (http://pharobooks.gforge.inria.fr/PharoByExampleTwo-Eng/latest/PetitParser.…) might be helpful. CU, Udo On 22/12/14 06:26, James Foster wrote: > 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 > > >
