At the heart of the environment is the Trellis incremental compiler which reduces the Trellis language to native machine code.
Michael Kilian joined Digital Equipment Corporation in 1985 and for the past five years has developed Digital's Trellis incremental compiler and examined object-oriented databases.
These include a graphical project manager for organizing source code files, libraries, and project resources; a browser for examining networks of classes, methods, and instances; a debugger for viewing the contents of running programs and stepping through programs one source code line at a time; a powerful interactor, which allows individual Dylan language expressions to be compiled and executed inside a running program; and an optimizing
incremental compiler, which produces efficient code while also allowing individual classes and methods to be recompiled and redefined in running programs.
