#" ... "# | Liberal String | S |
|
| Allows for the easy specification of strings (especially C code
snippets) with special character escaping turned off. | |
|
C-MENT | (C-MENT [,c-snippet ,goo-form]*) | S |
|
| Specifies a C statement formed as the
concatenation of c-snippets (goo strings) and
GOO forms 2.
The GOO forms are evaluated at runtime as embedded C expressions in the
lexical context of the c-ment expression.
If specified at top level, then the c-ment form
will be evaluated prior to the
evaluation of non c-ment top level forms.
| |
|
C-EXPR | (C-EXPR [,c-snippet ,goo-form]*) | S |
|
| Same as c-ment but specifies a value producing C
expression instead. | |
|
to-c | (x) | G |
|
| user extensible protocol for converting a GOO object to a C
value. Methods are provided for <int>, <flo>,
<str>, <chr>, <log>, and <loc>. | |
|
#{ ... } | Inlined C Statement | S |
|
| Shorthand for c-ment allowing GOO forms to be
specified with a $ prefix and the conversion of GOO
objects into C values specified with an
@ prefix, with @x == $(to-c x).
For example,
(df f (x) #{ printf("Got %lx", $x); })
prints out the GOO value x.
A callback can be defined at top level as follows:
#{ int gl_idle(int x) { $(gl-idle); } }
C headers can be included similarly:
#{ #include "GL.h" }
C expressions can be nested within embedded GOO expressions as follows:
#{ int gl_idle(int x) { $(gl-idle #ei{ x }); } }
in order to access lexical apparent C variables etc.

|
#ec{ ... } | Inlined C Expression | S |
|
| Similar shorthand for c-expr also allowing a single
character code c for specifying the conversion of C values back to
GOO objects. The valid codes are i for <int>,
f for <flo>, s for <str>,
c for <chr>, b for <log>,
l for <loc>, g for none.
For example,
(d. $gl-line-loop #ei{ GL_LINE_LOOP })
defines a top-level OpenGL constant.

USE/LIBRARY | (USE/LIBRARY ,name) | S |
|
| adds ,name to list of libraries to be linked against. | |
|
USE/INCLUDE | (USE/INCLUDE ,name) | S |
|
| adds ,name to include directory search path. | |
