The parsers do not perform any semantic analysis or type-checking during the parse.For example, headers are skipped when generating an AST for displaying code structure in the outline view. This allows features that work on code in an open editor to be fast. The parsers are able to skip header files that are included in a source file.In particular the main design influence of the DOM parsers is performance. To generate “completion nodes”, these are special objects that are used by CDTs content assist engine.ĬDT is not a compiler, it is an IDE, and so the parsers in CDT have different requirements from the kinds of parsers that would be used as the front end of a compiler.Many of CDTs features are implemented as algorithms that process the AST. The AST is a data-structure that is used as CDTs internal representation of the user’s code.

To generate an Abstract Syntax Tree (AST) from source code.

The role of the parsers is the following:

What makes these features work is CDT’s ability to analyze the user’s code, and the first step in analyzing code is to parse it.ĬDT contains two parsers, for C and C++, that are known as the DOM (Document Object Model) parsers. by add more visit method like the following below, then all king of statement can be visited.CDT provides powerful features that make C/C++ development much easier such as search, code navigation and content assist. tKind(ASTParser.K_COMPILATION_UNIT) įinal CompilationUnit cu = (CompilationUnit) parser.createAST(null) String source = sourceStart + sourceMiddle + sourceEnd add a fake class A as a shell, to meet the requirement of ASTParser
