Dear Unicon Users,
A new stable release of Unicon sources can now be grabbed via svn.
Windows users can head to
http://sourceforge.net/projects/unicon/
for a fresh binary release.
Below is a summary of the fixes and new features.
---Fixes:
- &level fixes for programs with co-expressions.
- udb is now functional.
- fix to the thread() function that could cause a deadlock in very rare
cases.
- fixes that allow multiple threads to run in graphical/gui application.
- RGB vs BGR color format fixes in some textures on X Windows?
- fix a problem that prevents unicon programs from being able to launch
from any other drive than c:\
- several other fixes especially to the IDE.
---Features/Improvements (Fixes?)
* Blanks are allowed in Unicon installation path
* more portable .u files.
* the ability to move the unicon directory without having to recompile the
libraries or rebuild iconx
* Thread safe initial clause, in other words, the initial clause is a
built-in "very efficient" critical region.
- Recursion in an initial clause is a runtime error
- fail, return and suspend are likely to cause a deadlock if used in an
initial clause, so don't do it!
* open(wildcard) returns a list of files that matches the wildcard. ex:
open("*.icn")
* 3D Facilities: Preliminary and Experimental Dynamic Texture support
You can draw live on textures now! if you have
tex := Texture("some image file")
you can do the things like
DrawLine(tex, 10, 10, 50, 50)
which will draw a line directly in a texture already rendered in a 3D
scene.
tex is just another "window" form the point view of this function.
Functions supported so far to work with textures include:
DrawLine(tex, ....)
DrawPoint(tex, ...)
DrawRectangle(tex, ....)
DrawSegment(tex, ...)
FillRectangle(tex, ...)
EraseArea(tex, ...)
CopyArea(sourcewindow, tex)
Thank you for your continuous support. :)
Your feedback is highly appreciated! Enjoy coding with Unicon!
Cheers,
Unicon Development Team
P.S. Windows users: We hope you will like the new look of the installation
wizard and the new icons!
