# The Free Linguistic Environment (FLE)
(C) 2016-2018 by [Damir Cavar]
The [Free Linguistic Environment] ([FLE]) is a project to develop a grammar engineering platform for the
[Lexical Functional Grammar] ([LFG]) framework. The parser in [FLE] is geared towards parsing natural
language sentences using grammars written in the [LFG]. It is mainly developed using [C++11] or newer [C++]
language specifications.
## Introduction
The main contribution in this code collection is the definition of the Xerox Linguistic Environment (XLE) grammar formalism. The different grammar parts and formalisms have been mostly completely defined using [BNFC]. You can use [BNFC] to generate the parser code for the grammar files and formalisms. Any code target that [BNFC] supports can be generated, that is in particular C++, Haskell, Java, C#, etc.
If anybody is interested in taking this on to generate parsers and help with the project to make all old XLE grammars
sustainable in an open and free parser environment, please let me know.
A lot of work went into this project, numerous contributors have helped with the environment and testing the formalisms.
## Build and Install
In the *requirements.md* file you might find more details about software and library requirements.
This is a brief overview of the components that are needed to develop [FLE]:
* [CMake]
* [G++] and [GCC], or [clang], or some other [C++11] compatible alternative compiler
* [Foma] with libraries
* [BNFC]
* [Boost] libraries
If you do not want to use [CLion] or a similar environment, and if you are using [G++]/[GCC], in the
source folder compile using the following commands:
mkdir build
cd build
cmake ../.
make
