VisualCQL6.2 is a user-friendly Windows extension (IDE) allowing to run CQL engine without
using a command line interface.
It has also several features to accelerate and ease the whole working process.
For example code enhancer (first two characters are enough) and built-in help
system.
You can run scripts and study results directly from VisualCQL environment.
VisualCQL6.2 was developed by Emil Vlasak, integrated PGN Viewer uses free code from Uwe Auerswald.
VisualCQL is
free after e-mail registration on
emil@vlasak.biz.
Anonymous download is no more available.
CQL6.2 is backward compatible with 6.1.
Therefore, you can run old scripts with several new pleasant
filters like
- puremate, modelmate,
idealmate (or stalemate)
- piecename
- typename.
Although the concept of CQL was based on the current position, a new filter of
currentmove is now available.
The new filter try simplifies testing of sub-lines
logic.
Also interesting is the similarposition filter that
allows comparing positions in two different PGN databases.
However, main innovations bring dramatic changes.
Essential filters move and line
are considered deprecated and should be replaced by
dash (--) and path more
powerful ones.
Newly, images are used in preference to keywords
for some filters.
Images are glyphs from Unicode true type fonts.
The authors developed special font CQLChess for this purpose.
The main problem - entering these characters - is solved in VisualCQL6.2 with a
mouse-supported palette (see picture below).
