At the request of Tim, I've done some tweaking of the lambda expression support
in propertysheets (so, pTk and Autopackage files)
Previously, you could expand out a collection as a collection of key/value
pairs via a template:
#define {
colors: {
"red" , "green"
};
};
someRule {
someProperty : {
colors => "label" = "value is ${each}";
};
someotherProperty : {
colors => "label-${each}" = "value is ${each}";
};
};
which would expand out to:
someRule {
someProperty : {
"label" = {
"value is red",
"value is green"
};
};
someotherProperty : {
"label-red" = "value is red";
"label-green" = "value is green";
};
};
Now, I've enhanced the collection support so that it can take multiple
collections :
#define {
platforms: {
x86 , x64
};
compilers: {
vc7 , vc8, vc9
};
};
someRule {
someProperty : {
(compilers, platforms) => "permutations" = "do something with
compiler=${0} and platform=${1}";
};
};
which would expand out to:
someRule {
someProperty : {
permutations = {
"do something with compiler=vc7 and platform=x86",
"do something with compiler=vc8 and platform=x64",
"do something with compiler=vc9 and platform=x86",
"do something with compiler=vc7 and platform=x64",
"do something with compiler=vc8 and platform=x86",
"do something with compiler=vc9 and platform=x64",
};
};
};
It can multiplex multiple collections, and
Tim will likely have a field day simplifying the .buildinfo files with this,
and that will help explain how it's useful...
Oh, and I've made trailing semicolons after a close brace { optional.
