`plasp` 3 is in early development and not intended for productive use yet.
As of now, `plasp` 3 experimentally supports the full [SAS Format](http://www.fast-downward.org/TranslatorOutputFormat) (as of version 3) used by [Fast Downward](http://www.fast-downward.org/).
`plasp` 3 translates planning problem instances to ASP facts.
`plasp` 3 supports the input languages [PDDL](https://helios.hud.ac.uk/scommv/IPC-14/software.html) (only basic features currently) and the [SAS](http://www.fast-downward.org/TranslatorOutputFormat) (full support of the current version 3), which is used by [Fast Downward](http://www.fast-downward.org/).
Please get in touch with [Patrick Lühne](https://www.luehne.de) if you have any suggestions.
## Usage
To translate an SAS file into ASP facts, call:
### Translating PDDL to ASP Facts
PDDL instances are translated to ASP facts as follows:
```bash
$ plasp file.sas
$ plasp domain.pddl problem.pddl
```
For example, a PDDL instance can be solved as follows.
First, use [Fast Downward](http://www.fast-downward.org/) to translate the files from PDDL to SAS:
Alternatively, PDDL instances may first be translated to SAS, the output format of [Fast Downward](http://www.fast-downward.org/).
```bash
$ ./fast-downward.py --translate --build=release64 domain.pddl instance.pddl
```
This creates the file `output.sas`.
The translated SAS instance can now be solved incrementally with `clingo` and the meta encoding `meta-sequential-incremental.lp`:
This creates a file called `output.sas`, which may now be translated by `plasp`.
```bash
$ plasp output.sas > instance.lp
$ clingo encodings/meta-sequential-incremental.lp instance.lp
$ plasp output.sas
```
### Solving the Translated Instance
The translated instance can now be solved incrementally with `clingo` and a meta encoding, for instance, `pddl-meta-sequential-incremental.lp`:
```bash
$ plasp domain.pddl problem.pddl > instance.lp
$ clingo encodings/pddl-meta-sequential-incremental.lp instance.lp
```
## Building
`plasp` requires a C++14 compiler (preferrably GCC ≥ 6.1), the `boost` libraries (≥ 1.55), and CMake for building.
`plasp` requires a C++14 compiler (preferrably GCC ≥ 6.1 or clang ≥ 3.8), the `boost` libraries (≥ 1.55), and CMake for building.
