A very simply sh-like unix shell written in C using recursive descent parser technique. WHY Last summer, I started out writing a shell for my assignment. Thought I'd share it as well. I'll explain this in conjunction with the project hosted in GitHub. Please download it and have your ...
cparser is a recursive descent C99 parser written in C99. It contains a preprocessor, lexer, parser, constructs an AST and does semantic analysis. It acts as a frontend to the libFirm intermediate representation library. This way optimization and code generation is performed. The compiler supports...

void* “AnnotationValue” — This contains an opaque object that the parser gets from Sema. The parser merely preserves the information for Sema to later interpret based on the annotation token kind. TokenKind “Kind” — This indicates the kind of Annotation token this is. See below for the...

aThe corresponding recursive ascent-descent parser, coded using a small extension to C, is shown in Figure 1. Our C extension occurs with return statements. We have used the notation return*k to indicate that a k-level function return is to be made. That is, return*l is identical to the...
You should also think about what functions/procedures you will need. You may want to consider basing your recursive descent parser as basis for parsing input. Each statement starts with a command, so write a function to parse this command. Based on the command you will know what you expect ...
