[Pharo-project] Default Background

by Torsten Bergmann

I dislike the white background in the default Pharo distribution. On the other hand a real wallpaper would blow up the image too much. So here is a small compromise (pattern background) that is easy to put into the update stream and looks good with most of the polymorph themes: -------------------------------------------------------------------- |colors form| colors := Array new:256 withAll: #(0.0 0.0 0.0). colors at: 1 put: #(0.329 0.329 0.329); at: 2 put: #(0.204 0.204 0.204); at: 3 put: #(0.267 0.267 0.267). form := ((ColorForm extent: 1@10 depth: 8 fromArray: #( 16777216 0 33554432 33554432 33554432 33554432 33554432 33554432 33554432 33554432) offset: 0@0) colorsFromArray: colors).

If I can choose, I will obviously choose to do as much as possible in the smalltalk world. However, this is not always possible. If this Juan fonts were as fast (or better) as TrueTypes and as nice of them, I would choose Juan's work.

I would change 2 little things: "This directory contains a pre-built Pharo Virtual Machine (VM). So it should not be necessary to build your own VM in order to use this software." This is not ALWAYS true. Many people with 64bits or a different architecture (like the other day with alpah) has to compile the VM to make it work. So what I would do is to clarify where (hardware) this VM must work The other little thing I would add (yes, it is obvious) is a first step when you explain to run from command line, that explains how to unzip the zip and to be clear that the "squeak" file is the one that it is where you unzip the zip.
