Re: Writing Compilers in Functional Languages

Hello,


IMHO, functional language is a better tool for compiler implementation
then procedural/OO one. So, I am agree with the author of the thread.
I've tried to make compilers using both general-purposed functional
languages and specialised compile compilers, based on functional
languages, and finally I have chosen GENTLE compiler compiler
(http://gentle.compilertools.net).


It provides compiler developer with metalanguage that allows easily
express concrete/abstract syntax, tokenization, token coordinates in
source code, parsing, global lists and tables, internal
representation(s), type checking, callgraph operations, any
optimizations, etc cetera - for up to code generation. Besides, C
subroutines (error messages, command line key processing ...) can be
easily used together with source code written in GENTLE, though this
metalanguage is of a very high level of abstraction. The thing is, it
allows to express these aspects in a more human-readable way, then
other tools of the kind.
