C# Parser (Front End)

The C# parser(front end) enables the construction of C# custom compilers, analysis tools, or source transformation tools. It is a member of SD's family of language front ends, based on first-class infrastructure (DMS) for implementing such custom tools. The C# front end includes:

  • Lexical analysis including ASCII, ISO 8859-1, and UNICODE
    • Conversion of literal values (numbers, escaped strings) into native values to enable easy computation over literal values
    • String literals represented internally in Unicode to support 16-bit characters
  • Explicit grammar directly implements C# ECMA 334 standard
  • Covers Microsoft dialects 1.2, 2.0, 3.0 (including LINQ) and 4.0
  • Automatic construction of complete abstract syntax tree
    • Capture of comments and formats (shape) of literal values
    • Capture of ambiguous parses during parsing
    • Ability to parse large systems of files into same workspace, enabling interprocedural and cross-file analysis/transformation
    • Ability to parse different languages into same workspace, enabling cross-language analysis/transformation
  • Facilities to process syntax trees
    • Complete procedural API to visit/query/update/construct/print syntax trees
    • Source regeneration by prettyprinting and/or fidelity printing of syntax trees with comments and lexical formats
    • Automatically generated source-to-source transformation system
    • Ability to define custom attribute-grammar-based analyzers
  • Available as source code to enable complete customization
    • Means to manage multiple language dialects with highly shared common core
  • Robustness due to careful testing and application across many customers

Many of these facilities come as a consistent consequence of the front end being built to top of DMS.

Here are some sample tools (many offered by SD as products) built using the C# front end:

Your organization may use DMS with the C# front end to implement and deploy your own custom tools. The sample tools can be obtained in source form as part of the C# front end for customization. Semantic Designs is also willing to build custom tools under contract.
