Slow World Menu opening
by Alexandre Bergel Aug. 26, 2015

Aug. 26, 2015

Hi! When I open the world menu, the mouse cursor is intensively blinking, and opening the menu is _very slow_. This bugs has been around for a couple of weeks already. Am I the only one to see it? I have checked the cause, and apparently the problem disappear by removing the use of âCursor read showWhile:â. The following method: -=-=-=-=-=-=-=-=-= ImageReadWriter>>formFromStream: aBinaryStream "Answer a ColorForm stored on the given stream. closes the stream" | reader readerClass form | readerClass := self readerClassFromStream: aBinaryStream. reader := readerClass new on: aBinaryStream. Cursor read showWhile: [ form := reader nextImage. reader close ]. ^ form -=-=-=-=-=-=-=-=-= May be rewritten as: -=-=-=-=-=-=-=-=-= ImageReadWriter>>formFromStream: aBinaryStream "Answer a ColorForm stored on the given stream. closes the stream" | reader readerClass form | readerClass := self readerClassFromStream: aBinaryStream. reader := readerClass new on: aBinaryStream. form := reader nextImage. reader close. ^ form -=-=-=-=-=-=-=-=-= However, changing the cursor has been around for quite a long time. It is strange that the slow menu is surfacing only now. Any idea why?

How can an object have its "self" and "name" instance variables nil after being instantiated?
by Julien Delplanque Aug. 25, 2015

Aug. 25, 2015

Hi, I have an object that override KMCategory and that is initialized and added to "KmRepository default" using #postLoadDoIt: message in BaselineOf after the package is loaded in an image. But once it is loaded I have huge problems with keyboards entries, they do not work any more, I get an exception each time I press a key. If I inspect the Singleton class variable of my category object I can see it contains an instance of my object that have its "self" variable nil and its "name" variable nil. Others variables look fine. How is it possible? I can remove my custom KMCategory by copy/paste code from sublime text to Pharo and left click/do it and then everything is fine with my keyboard: no more exception and it behave correctly. Thanks in advance, Julien

Multi desktops inside Pharo!
by Julien Delplanque Aug. 24, 2015

Aug. 24, 2015

Hi all, I created a small utility that make possible to have multi desktops: https://github.com/juliendelplanque/desktopsmanager. It show/hide windows according to the desktop you're on. I think it can be useful from my small experience, I often feel a lack of space when opening 4-5 windows and also, I like to have my windows full sized... :) What do you think about it? Regards, Julien

Re: [Pharo-users] [Pharo-dev] issue with large file path on windows

Where does its parameter "char* fileNameIndex" get its null termination? I can only guess maybe the following definition in primitiveFileDelete.st [2] <var: 'nameIndex' type: 'char *'> automatically appends a null to the Smalltalk string. My understanding is that the Smalltalk string's internal representation is not null terminated. I ask since the sqFileDeleteNameSize()'s comment "convert the file name into a null-terminated C string" indicates the null is added by MultiByteToWideChar(), but [3] indicates that is not true -- that the output of MultiByteToWideChar() is only null terminated if the input is null terminated. Also, anyone know if the concern "BIG WARNING about the return value and the `cbMultiByte` parameter" expressed near the end of [3] is relevant?

issue with large file path on windows
by Nicolai Hess Aug. 24, 2015

Aug. 24, 2015

For those who had problems with pharo on windows and github based repositories, I built a windows vm with support for long paths: https://drive.google.com/file/d/0B8yEahnuIem2bmxwdzJuUXFxVGM/view?usp=shari… For browsing directories with large paths (FileList or Inspect), you may need one additional change in the image (But I am not really sure about that) : DiskStore>>initialize super initialize. maxFileNameLength := Smalltalk vm maxFilenameLength ifNil: [ 32767 ]. please test and give feedback. This wasn't as easy as I thought, and I had to make some more changes for the file permissions (the stat-functions don't work for files with long paths). Please test other file/folder operations. nicolai
