Dissecting a C# Application: Inside SharpDevelop

Research complex . web programming suggestions via getting an insiders' examine a whole program! SharpDevelop is a whole built-in improvement setting, written in C#. It comprises all of the complex positive factors that programmers anticipate from a contemporary IDE and, after all, imposing those beneficial properties has required a few complex programming thoughts.

Example text

Chapter 6 describes the various program transformations, most notably the insertion of explicit synchronization operations, required to turn λC into a form suitable for code generation. Chapter 7 describes the final code generation step which maps canonical λC to C code. Having described the basic hybrid implementation, the next two chapters fill in crucial detail. 30 Chapter 8 explains how type and strictness information are used to identify divergent expressions, and how these expressions are handled by the compiler and the run-time system.

In each case the store rule corresponds to allocating space for x and storing v into that space. Instantiation corresponds to fetching values previously stored to the heap. An actual implementation fetches a value only when it is needed. 3. 8 Placing non-values on the heap Every strategy presented in this chapter except for call-by-value permits non-values to reside on the heap. This has substantial impact on the language implementation: values and non-values must be 60 represented in a way that allows them to be distinguished.

All our strategies restrict reduction to the working terms in the program. Only the rules in Figure 4-2 manipulate the structure of the stack and heap. Thus, the local evaluation rules which carry over from Figure 3-12—τa , ν, δ, χ—are wrapped in the following context: letrec h • x = ;k r 58 t in main These rules correspond to local evaluation and local control flow; they will be implemented in a very similar manner regardless of reduction strategy. 4 Function calls: manipulating the stack The βvar rules and the return rule manipulate the stack, and therefore operate on the stack as a whole: letrec h • t in main An ordinary full-arity function call pushes a frame: −→ letrec h • x = (λxk → e) yk ; k r t in main letrec h • x = e [y / x] k r t in main (call) The body of the function is instantiated and pushed onto the stack.
