Hi All,
A new version 1.5.0 of gcmc has been released.
There have been quite a few changes on the syntax and semantic level, as
well as additional built-in functions for various things.
An important semantic change is how add/subtract (+ and -) handles undef
values. A second set of operators +| and -| supplement the new semantics.
Another feature is passing function arguments by reference. This allows
for better abstractions for some types of constructs (as multiple return
values) and can improve execution speed if you are handling huge
vector-lists.
Several more language features are implemented to make gcmc more
expressive and closer to what other programming languages provide, such
as ternary operator (?:) and pre/post increment/decrement as part of
expressions. A repeat() {} construct enables quick and simple loops that
need to be executed a fixed number of times.
Canned cycles have been added as library functions. There is no point in
calling underlying canned-cycle-gcode because gcmc already possesses all
tools to perform the operations using G0/G1/G4 primitives. Letting gcmc
handle canned cycles also makes the resulting gcode more portable. An
example is provided in the tarball.
The documentation has been updated to include all the changes and adds a
new documentation for library functions (see below for link).
The list of changes for version 1.5.0 is long, so I'm not going to
include the details here. You can find the list on the gcmc homepage.
You can get the new version from the homepage:

The updated documentation is online at:

http://www.vagrearg.org/content/gcmc-syntax
http://www.vagrearg.org/content/gcmc-funcref
http://www.vagrearg.org/content/gcmc-library
All documentation is, of course, included in the tar-ball distribution
and now also added to the windows zip-file.
As usual, let me know if you encounter bugs or have any questions or wishes.
