[ANN] Pharo wiki , is here

by Dimitris Chloupis

Many seemed to like the idea of a Pharo wiki , I like it too. I created one, can be found here and super easy to contribute to. https://github.com/SquareBracketAssociates/PharoWiki Will keep this thread for alerting for important updates to wiki. Have fun :)

Take a task no one is particularly invested in and show off Pharo's advantages by adding real value to the team. Very sneaky...

Re: [Pharo-users] How to find where pharo is killing processor power?

by Dimitris Chloupis

it depends what you mean if you talk about Pharo code then those tools should be enough , unless it freezes Pharo (a 100% consumption does not necessarily imply a freeze) if you talk about the Pharo VM itself then you will need to use one of the countless profilers that exist for C/C++ . Some OSes come included with them. MacOS which what I am using can sample a running process and tell you exactly which function/method consumes how much CPU. Obviously more specialised tools can be even more of an assistance like Valgrind http://valgrind.org/ But then it will require knowledge of the Pharo VM internals. if it freezes pharo and you know its pharo code then its a matter of taking a look at changes file and testing on a new image one change at the time until you identify the code that causes the slow down. At least that is what I have done one time I really messed up Morphic draw loop and froze my image.

P.S. I assume I need to get a developer version. How do I do that? On 8/19/17, H.

Tealight (similar to Teapot) installs fine in Pharo 6.1

Hello Torsten Tealight installs very fine into the latest Pharo release (6.0 / 6.1).

Re: [Pharo-users] YAML parser (2017)

by H. Hirzel

Peter, thanks for the confirmation that in your installation of the PetitYAML grammar all tests are green. I wonder how you did it. This is what I did: 1. I put Pillar on the back burner for the moment and 2. I went for a pristine Pharo 6.0 Latest update: #60510 image (a.k.a. 6.1). 3. Then I installed PetitParser only through the catalog -- the entry is still tagged for Pharo 5.0 4. Then I added PetitYAML Name: PetitYAML-PhilippeBack.11 Author: PhilippeBack Time: 29 May 2017, 12:53:55.994195 pm UUID: d7658233-112c-754c-81a7-d60139bb9549 taken from MCSmalltalkhubRepository owner: 'Moose' project: 'PetitParser' user: '' password: '' 5. Running the tests gave me 76 run -- 76 errors What am I missing here? Is there an easy workaround to get PetitParser with PetitYAML into 6.0-#60510 (a.k.a. 6.1) ? --Hannes
