Add ability to specify recipes in separate files
This can now be achieved with the new `recipe` directive: recipe <language> <file> Note that similar to the use of if-else and switch directives with recipes, this directive requires explicit % recipe header. For example, instead of: file{foo.output}: {{ echo 'hello' >$path($>) }} We can now write: file{foo.output}: % recipe buildscript hello.buildscript With hello.buildscript containing: echo 'hello' >$path($>) Similarly, for C++ recipes (this time for a pattern), instead of: [rule_name=hello] file{~'/(.+)\.output/'}: % update clean {{ c++ 1 -- -- ... }} We can now write: [rule_name=hello] file{~'/(.+)\.output/'}: % update clean recipe c++ hello.cxx With hello.cxx containing: // c++ 1 -- -- ... Relative <file> paths are resolved using the buildfile directory that contains the `recipe` directive as a base. Note also that this mechanism can be used in exported buildfiles with recipe files placed into build/export/ together with buildfiles.
