Fudgets

Version h10 Release Notes

SUMMARY OF CHANGES

This file describes the most important changes since the previous release.

Changes from the 9th (July 95) to the 10th (May 96) hackers' release

The primary purpose of this release of the Fudgets library is to provide a version that works with Haskell 1.3. Apart from the necessary changes for this, there are only some minor additions and changes:

Poor mans resources added. In previous releases you could select fonts and colors etc by using command line switches. Now you can also use environment variables. The value of a resourse called Key, e.g., buttonfont, is now taken from
1. the command line: if -Key value is present, else
2. the environment variable FUD_Prog_Key (where Prog is the name of the program), if it exists, else
3. the environment variable FUD_Key, if it exists, else
4. a built-in default.
Some new graphics support. There is a new class Graphic whose instances are types which have graphical representations. Most basic types, and strings, are instances of this class. There are also some new types for graphics, but they are still work in progress and are not documented yet.
Some fudgets have been generalised to display arbitrary graphics instead of just strings, e.g.,
buttonF :: (Graphic a) => a -> F Click Click
