The main objective of this thesis is a system that integrates a powerful library system and a powerful syntactic abstraction facility without compromising the essential properties of these systems. In this system, a library serves as a building block for language extensions, and its exported definitions can be used anywhere in the importing library without restrictions. The run-time variable definitions and the compile-time syntax definitions provided by a library are unified and can be used in the importing library’s run-time and compile-time code alike. As a unified and integrated framework, all run-time facilities are extended to compile time, and all compile-time facilities are similarly available at run time.
The dependencies between libraries is specified in two parts. For each library, the user specifies only the import dependencies. The compile-time, expand-time, and run-time dependencies between libraries are derived automatically by the system based on the program source code, which is used as an implicit specification for phase dependencies.
Compared to traditional systems that require that the user explicitly specify phasing dependencies, the implicit phasing system (1) is easier to use, (2) derives more precise dependency information, (3) is efficient, and (4) is straightforward to add on top of existing hygienic syntactic abstraction systems.
