Hello!

This is my second thread here. My first thread was wrong placed and little messed up.

So, I'm new here!

But I have a question!

Is Compiler-compiler used to let you make your own Compilers?

Excuse my English. I'm from Norway.

Yes, generally in conjunction with other tools such as lexical analyzers. Welcome.

Welcome,

and i think this is topic is the wrong place for your question again

i think what u mean is a parser generator. It takes more to build a compiler than parsing correct syntax (lexical-analysis,semantic-actions and so on).

Usually compilerbuilders build a "dirty" compiler in a different language than the one the compiler is supposed to compile. They then use this dirty compiler to compile a compiler written in the language the compiler is supposed to compile. This is called boot-strapping. So this dirty compiler is what i call a compiler-compiler gg

I read some place that Pascal was built for making Compilers.
My dream is to make a powerfull Compiler, there is one goal: To make your own Compilers.

One of the early Unix utilities was YACC, which stands for "Yet Another Compiler Compiler."

@DaWei nomen est (not allways) omen.

I think the naming is a bit confusing as , and i'm sure u know that, yacc which is a predecessor of bison just eats in grammar-files and spits out a parser written in C.
It does not a compile a compiler or things like that.

The grammarsyntax is very similar to BNF or EBNF i believe, though my bison-times are over for a fair few years by now. I don't know it for sure but i think yacc produces a bottom-up (shift-reduce)-parser as it is capable of handling left-recursion as far as i'm concerned. But again you do not have a full-blown compiler just by generating a parser.

That's hardly a tutorial. Since I haven't even looked at it since the early '80s, and my memory has gone to hell in a handbasket, I can't comment on anything but the name .
