Re: [Pharo-project] Strange logic in PolygonMorph>>fromHand: hand

by Fernando Olivero

Indeed is weird. I think it has to explicitly call runStepMethods, because it's not forking , thus taking control of the ui process, does it make sense? I would remove the method (and all the similar ones found in the image, that explicitly reference Sensor and while doing "true whileTrue:[ ...]", if needed it would be have to re-done using the new event model with announcements.

So just find any text area (inspector, workspace, code browser ) type the selector you are looking for (here renderContentOn:) then select the selector and do cmd+m for implementors, cmd+n for senders It should do what you want :) Ben On May 13, 2012, at 8:11 PM, blake wrote: > On Sun, May 13, 2012 at 10:54 AM, Benjamin > <benjamin.vanryseghem.pharo(a)gmail.com> wrote: >> I don't get it I think ... >> >> You want to retrieve the classes that implements renderContentOn [snip] > > This is what I want.

[Pharo-project] Test coverage on branch level?

by Stefan Marr

Hi: I was looking for something that could visualize code coverage on the branch/statement level. My understanding is that the test coverage tool provide by the test runner only tells me which methods haven't been called. I also had a look at Hapao. First I found that the linked image was rather old [1], but even after loading the latest version into a fresh image, I still had the feeling that it provides me with a lot information that is not immediately helpful to answer my questions. >From the C world, I am used to things like gcov and lcov [2], where I can see immediately which branches haven't been covered. Is there something similar available in the Pharo universe? Reading a recent thread on the mailing list [3] gives me the impression: 'not yet'?

I don't want to have to find a class that implements renderContentOn first, and then go to the renderContentOn method, right-click and select "implemenors of". Happens to me all the time.

[Pharo-project] Fun with spock (NativeBoost FFI)

by Lawson English

So, thanks to Igor Stasenko, I've managed to learn how to (sorta) use the new NativeBoost FFI (spock). We (he) implemented a binding to a few of the gmplib functions. gmp is the GNU Multi-Precision Library. Here is a simple benchmark of the Pharo factorial method vs the gmplib mpz_fac_ui() function. As might be expected, gmplib is faster for any test larger than 13 factorial, as LargePositiveInteger starts to become involved, and the speed differential becomes rather huge as larger integers are tested: 1000 factorial time to run with: squeak: 2 ms gmplib: 0.004 ms ratio: 50.0 11000 factorial time to run with: squeak: 354 ms gmplib: 0.191 ms ratio: 185.34031413612567 [...] 91000 factorial time to run with: squeak: 34598 ms gmplib: 4.759 ms ratio: 727.0014708972473 Running on a Mac OS X Snow Leopard 2.8Ghz, with NBCog and 1.4 Pharo image. benchmark: a := GMPzWrapper new. 1000 to: 100000 by: 10000 do: [:i| squeakTime := [ i factorial] timeToRun.

Re: [Pharo-project] implementors of...

I don't get it I think ... You want to retrieve the classes that implements renderContentOn in the case you do not know a method containing a call to this selector ? Am I right ?
