Описание тега alex

Alex is a tool for generating lexical analysers in Haskell, given a description of the tokens to be recognised in the form of regular expressions. It is similar to the tool lex or flex for C/C++. Haskell is a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing.

Note: Alex is part of the Haskell Platform, thus when you install the platform you will automatically have a working Alex. The Haskell Platform is a single, standard Haskell development environment for everyone. It offers a set of blessed libraries and tools, to save you the task of picking and choosing which core Haskell libraries to use.
