# Grammatical Framework (GF)
|
|
|
|
[](https://travis-ci.org/GrammaticalFramework/gf-core)
|
|
|
|
The Grammatical Framework is a grammar formalism based on type theory.
|
|
It consists of:
|
|
|
|
- a special-purpose programming language
|
|
- a compiler of the language
|
|
- a generic grammar processor
|
|
|
|
The compiler reads GF grammars from user-provided files, and the
|
|
generic grammar processor performs various tasks with the grammars:
|
|
|
|
- generation
|
|
- parsing
|
|
- translation
|
|
- type checking
|
|
- computation
|
|
- paraphrasing
|
|
- random generation
|
|
- syntax editing
|
|
|
|
GF particularly addresses four aspects of grammars:
|
|
|
|
- multilinguality (parallel grammars for different languages)
|
|
- semantics (semantic conditions of well-formedness, semantic properties of expressions)
|
|
- grammar engineering (modularity, abstractions, libraries)
|
|
- embeddability in programs written in other languages (C, C++, Haskell, Java, JavaScript)
|
|
|
|
## Compilation and installation
|
|
|
|
The simplest way of installing GF is with the command:
|
|
```
|
|
cabal install
|
|
```
|
|
|
|
This can be broken down into the usual sub-steps:
|
|
```
|
|
cabal configure
|
|
cabal build
|
|
cabal copy
|
|
```
|
|
|

## About this repository
|
|
|
|
On 2018-07-25, the monolithic [GF repository](https://github.com/GrammaticalFramework/GF)
|
|
was split in two:
|
|
|
|
1. [gf-core](https://github.com/GrammaticalFramework/gf-core) — the GF compiler, shell and runtimes
|
|
2. [gf-rgl](https://github.com/GrammaticalFramework/gf-rgl) — the resource grammar library
|
|
|
|
The former repository is now archived and no longer updated.
|
|
The split was performed using [this script](https://github.com/GrammaticalFramework/GF/blob/30ae1b5a5f73513ac5825ca6712186ef8afe9fd4/split/run.sh)
|
|
and the output of that script is [here](https://gist.github.com/johnjcamilleri/a6c43ff61f15a9657b457ac94ab7db61).
