I agree I should post one, but it usually takes me a lot of time, and I wasn't sure how much interest there would be. I'll start working on one.

I started writing my own language in JavaScript last Summer but gave up after only writing the Lexer because I didn't know how to continue. I would LOVE to read this blog post!

Kaleidoscope - LLVM Tutorial [0] is an excellent resource with code samples in C++ and OCaml.

Agreed, it's an excellent resource. One of the best PL tutorials I've ever read.

But if you use the OCaml version with a recent version of OCaml, you'll run into a few issues. I sent in a patch with a few simple updates to the path mailing list earlier this year, but last I checked it wasn't merged.

Patch is here (it's a text file, despite the "bin" extension):

I also pasted the patch here:

Not all parsers need to be complex. If you're up for the challenge, read a bit on top-down parser and try to write it for your language!

There may be better books but this was fairly pragmatic and I learned a lot: http://www.amazon.com/Programming-Language-Processors-Java-I...

Niklaus Wirth´s book about compiler construction is quite good.

It is available at his ETHZ site nowadays,
