This is true, however I find a changes of 140 megs to be MASSIVE. I remember loading ~4000 classes in the order of 10^6 LOC in Dolphin, and changes never got half that size.

Re: [Pharo-users] AST tokens question

by Mark Rizun

In the first place why I'm doing this. I work on Rewrite Tool and it's main functionality bases on replacing nodes in AST. Plus it works with sourceIntervals of nodes. Untill now my solution was: if I replace node, I reparse tree to get intervals updated However this solution brought new problems. Second reason is, that I think it makes sense to update interval of all AST if you replace one node. For example, we have: obj1 foo + obj2 bar and we replace obj1 with myObject. The interval of ast was 1 to: 19, and now it should be 1 to: 23.

Re: [Pharo-users] the simplest program of "the world"

by Werner Kassens

Hi Hans, i guess you are asking for a way to make a batch file that when double-clicked immediately starts your program? a batch file with something like this: ~/pharo3.0/bin/pharo ~/pharo3.0/shared/yourImage.image ~/pharo3.0/shared/start.st would do that. start.sh should be a text file with for example this: SystemWindow new openInWorld. werner

Pratsch

by Hans Schueren

Thank you Thierry , guess i am an user. " I have heared there are Pharo programmers" Can i download such a program to see how good they are ? I dont want to hear anything about coding and IDE and development. I am a user and want to start a example program. Do you have a LINK for me to download ? Hans This sounds strange. However , i have here a huge range of books about smalltalk 80. All the books describe the syntax and system. To write a better and better code and more functions. The only thing that is not describes is to display a running program inside image. The keywords and methods to display and save the own code inside the packages in the form of "image out" a manipulated smalltalk image to run as a user program. The first step is a really really simple program like mathematic calculation etc. But the procedure of end product must be clear. Only one good example perhaps with a transcript display can overcome theese difficulties. Its all unclear : show Transcript openInWorld class new class Theese commands are messages to a object. But the user does not input any program code. This is automatic running. Anyway , if the Pharo.exe started the image in the program. How , and with what keyword is then the program started fullscreen - which World is invoked to display? This preparation point is unclear when i want to make my "Allready written program" ready to start. However , i make a break with smalltalk now. A few books are still ordered from USA. If this point is unclear i cannot learn further at this point. It makes no sense to write Packages and classes if i cannot invoke the running arrangements No matter if they are objects or others.

Hi Steph, I am using Pharo 3. I didn't try in it any other release. I'm using the latest stable version and VM from the zeroconf scripts, runing the command from the command line via "eval" (though it doesn't seem to make any difference) Regards!

Re: [Pharo-users] Pharo - OpenDBXDriver: Unsupported data type: UNKNOWN

by Guillermo Polito

Hi! Check that a row in Pharo's OpenDBX driver answers to: - #values it reads the value from the database and tries to convert it to the corresponding object representation (e.g., a mysql date to a pharo date) - #rawValues it returns a string representing the direct representation in mysql. So maybe if you use #rawValues you can query the database and do whatever you want with the "unparsed" value. Tell us if this helps you!
