Changelog for zeolite-lang-0.4.0.0

Revision history for zeolite-lang

[new] Allows modules to specify custom linker flags and private include paths in .zeolite-module. This lets categories written in C++ depend on external libraries written in other languages.
[behavior] Adds optimization of dependency inclusion for categories that are defined in C++ sources. This should eliminate linking in object files that are not needed by the binary.
[behavior] Adds checks to prevent a module from defining a category that was declared in another module.
[breaking] Updates the .zeolite-module format to require associating externally-defined categories with the source files that define them. This allows finer-grained linking of binaries and tests.

[breaking] Updates syntax for discarding all returns to use \ instead of ~. This will allow ~ to be used for bitwise-not later on. (Not to mention that ~ was kind of ugly in that context.)
[breaking] Cleans up multiple-return syntax by removing {}. This applies to both the return and the assignment.

[breaking] Requires that concrete categories defined in .cpp files be listed as external in .zeolite-module. This allows the compiler to ensure that all categories have a definition, which helps avoid linker errors.
[breaking] Gives .zeolite-module configs a proper file format.
[new] Adds version checking to cached module data.

[fix] Fixes a parser issue with empty {} blocks following scoped.
[behavior] Updates cleanup procedures to allow setting named-return values. Previously, initializing a named return in cleanup was not sufficient.
[behavior] Updates zeolite-setup to unconditionally rebuild supporting libraries. Incidentally, this causes all existing user modules to be out of date.

[behavior] Set the default output path for binaries to the module's path rather than the current directory.
[new] Allows a base path (-p) with recompile mode (-r).
