OCompletion for Squeak 4.2
by Levente Uzonyi 29 Oct '10

29 Oct '10

Hi, if you update your Trunk image to 10622, then OCompletion will work without the compatibility package. Evaluate the following script to install it: Installer squeaksource project: 'RoelTyper'; install: 'RoelTyper'; project: 'OCompletion'; install: 'Ocompletion-ul.74'. Smalltalk at: #ECToolSet ifPresent: [ :ecToolSet | ecToolSet register. ToolSet default: ecToolSet ]. Cmd+j support is a bit better, but still not perfect. Cheers, Levente

There is no such thing as 16-bit variables. > Don't know what would be the answer in a 64 bit image... On a 64-bit image, we have this: Smalltalk wordSize ==> 8 Bitmap isWords ==> true String isWords ==> false CompiledMethod isWords ==> false Array isWords ==> true FloatArray isWords ==> true IntegerArray isWords ==> true The result for String looks like a bug in the 64-bit image or VM (a 32-bit version of the same image answers true). The other results are the same as for a 32 bit image. For a 64-bit image, the word size is 8 and the things in the slots after the object header may be either 64 bits (object points, float values) or 32 bits (e.g. the elements in a FloatArray). For example, if you have (FloatArray with: Float pi with: Float pi), the object has a single 64-bit word containing two 32 bit float values. However, if you have (Array with: Float pi with: Float pi), the object will have two 64 bit words containing the object pointers for two Float objects. Dave

Cog VM on Windows
by Tim Felgentreff 28 Oct '10

28 Oct '10

Hi has anyone tried the latest build of the Cog VM from http://www.mirandabanda.org/files/Cog/VM/VM.r2316/ on Windows? A fresh trunk image from ftp.squeak.org/trunk loads for me on MacOS Cog and Linux Cog builds, on Windows I get an "Image file read problem (0 out of 4 bytes read)". Any hints? Are there builds of the Cog VM known to work which I can try? Regards, Tim
