[Pharo-project] issue 5024: incomplete SUnit

Nov. 25, 2011

Messages #sunitExitxWith: and #sunitAnnounce:toResult: still have only *SUnit category in some classes. Because this package was renamed to SUnit-Core, this methods do not belong to any package. There would not be bad idea to check whole image ;-) -- Pavel

All of it. And then of course the annotations and resulting output model. I know practically nothing about the data at first (about 700 files, about 700 MB). When trying to understand the data, it is crucial that I can test hypotheses fast.

Delaying is crucial. If I wait long enough, PC's will have enough memory. Stephan

[Pharo-project] experience with large images?

Hi! Apparently, without configuring anything, the Pharo image cannot go over 500 Mb. Can this limit be moved up, to, let's say, 4Gb? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Re: [Pharo-project] Athens work in progress: couple screenshots
by Fernando Olivero Nov. 24, 2011

Nov. 24, 2011

Ah! So Athens is a facade, for a Canvas API, based on Paths, that could have a Cairo, OpenGl or BallonCanvas rendering engine as a backend. In the current case, using BallonCanvas (bit map based), i guess you are implementing the scalable fonts using the free type library? In Gaucho, i've done exactly that, i have a FontLibrary which acts as a cache for a particular font family, at a requested size. So when the canvas renders a string with a given font, it asks the library for the font at the current scale of the desired size. Although i prefer the abstractions that are present in Athens, and will try to use it instead eventually. Fernando pd: attached screen shot of Gaucho, using a scalable GCanvas (built on top of the free type lib and FormCanvas).

We are doing data conversion with Moose. Raw data is 740 MB. No 64-bit means being forced to make decisions early, and therefore wrong. It also forces us to do some batch processing. We're very lucky the customer has a good idea on what data to keep. Stephan

[Pharo-project] Monticello Browser Model
by Sean P. DeNigris Nov. 23, 2011

Nov. 23, 2011

MCWorkingCopyBrowser has #workingCopy:, which I thought would allow me to programmatically select a working copy. Unfortunately, it doesn't update the UI. Poking around, I found that there are two mechanisms to update the working copy list selection - #workingCopySelection: and #workingCopySelectionWrapper: - and they are not connected. So I ended up with the really ugly: browser := MCWorkingCopyBrowser new. wrapper := MCDependentsWrapper with: wc model: browser. browser workingCopySelectionWrapper: wrapper. So my question is: is it worth it to open an issue/work on this? Will Ring/RPackage/other-new-thing replace this tool anytime soon?
