Resources for writing a recursive descent parser b

问题:

I'm looking to write a recursive descent parser by hand and I'm looking for good resources on how to structure it, algorithms, etc.

回答1:

There is a good tutorial on codeproject under "Compiler Patterns". Lately, you can even just Google "compiler patterns".

http://www.codeproject.com/Articles/286121/Compiler-Patterns

The article covers most aspects of building a simple compiler (the back-end, the BNF, and the patterns used to implement the various BNF rules), but is not very heavy on theory, or even on why a recursive descent compiler works to convert language input into code.

I can suggest "Crafting a Compiler" by Charles N. Fischer and Richard J. LeBlanc.
