[M3devel] Fw: Re: Fw: UTF-16: Greek alphabet with CM3

[dirk muysers]

Forget Trestle/VBT and Cie. Modern GUI systems all offer platform
look and feel. The easiest solution is to create an import library for
IUP (http://www.tecgraf.puc-rio.br/iup/). IUP is a compact (about
a 100 "C" functions), portable and platform rendered GUI library.
BTW, it uses (since version 3.9) UTF-8 text. I still find that the
split of the character set into chars and wides was a very bad
decision. It is always stupid to follow the Microsoft trail, the
most incompetent software company (IMHO) in the world.

Unfortunately I am in need of an entire Greek alphabet because
automatons that have already been created with this program should
continue to work and be displayed correctly.

Great!
If you could guarantee me your assistance at least for the Trestle/VBT
issues in support of 16bit wide characters I would start to work on a
Modula-3 port. The thing is that I will need the port for my studies and
I do hardly want to take the risk in failing to hack Trestle/VBT though
the thing should not be that hard to do as Olaf has already indicated.
As far as I have researched things all that would need to be done is add
an additional painting operation to the PaintPrivate interface; or
perhaps a second one for drawing elliptical arcs rather than just using
Path.CurveTo and to make these new operations be used by the respective
painting primitives. Additionally I would welcome some styling of
buttons and bevels that goes ahead of pure black and white X-windows.
Some Qt-like or at least a Windows 3.1 like button and menu styling
might not  be unimportant for the acceptance of the application.
Nonetheless up to now I can not verify the impact of new painting
operations on ports for Windows and MacOS which I am not confident with.

No, it does not have a single goto; I`d consider it well structured as
it uses classes, objects, method variables and nested procedures and can
easily be extended for new automatons. At the moment I am still reading
into Trestle.

P.S.: I have already programmed a module converting between UTF-16 and
UTF-8 for console usage and am ready to publish it under BSD or any
non-infective license allowing to re-license under any license. I would
consider it really a pity if CM3 had good internal UTF-16 support but no
interface to make use of it in practice.

Additionally I could upload my still existent VIM environment for
hacking Modula-3 including syntax highlighting, a treeview buffer and a
backtrace analyzer to http://www.elstel.org/modula3 if anyone is
interested in it.
