Project Description
OpenGEODE
=========

OpenGEODE is a tiny open-source SDL editor that is developed for
the purpose of providing an easy to use and free state machine editor and
Ada code generator to the TASTE toolchain from the European Space Agency,
running in combination with ESA's ASN.1 "Space Certifiable" ASN.1 compiler.

SDL is the Specification and Description Language (Z100 standard from ITU-T).

This is NOT related to the graphical Simple DirectMedia Layer libraries!

Visit http://sdl-forum.org for more information about SDL.

![alt tag](icons/opengeode-screenshot.png)


Features
--------

- Graphical editor of SDL processes and procedures.
- SDL2010 features: state composition and state aggregation
- Works on pure PR+CIF files (textual SDL notation)
- Supports ASN.1 data types - using ESA Space Certified compiler (www.github.com/ttsiodras/asn1scc)
- Generates Ada code
- Automatic conversion to Statechart diagrams
- Save the complete or parts of the model to PNG/SVG/PDF files
- Hyperlinks (link a symbol content to any external document or web page)
- Context-dependent text auto-completion
- Syntax highlighting
- Undo/Redo, Copy-Paste
- (Limited) VIM mode - You can use :wq or :%s,search,replace,g, and /search pattern
- SDL to LLVM code generation
- Python API to parse and render SDL from other Python modules

Installation
============

On Windows, download the binary from [here](http://download.tuxfamily.org/taste/opengeode_windows.zip)

Uzip it and run opengeode.exe. It contains everything without any other external dependencies.

Linux Pre-requisites
--------------------

To install OpenGEODE on Linux you need to install some system-level dependencies:

- Python 2.7 with pip (installed by default on nearly all Linux distributions)
- Pyside
- Graphviz
- [ASN1SCC](https://github.com/ttsiodras/asn1scc)
- GNAT

And optionally llvm and llvmpy

On Debian, Ubuntu, and probably other distributions:

```bash
$ sudo apt-get install pkg-config python-pyside pyside-tools graphviz \
graphviz-dev libgraphviz-dev python-pip gnat-4.8 \
libmono-system-runtime4.0-cil libmono-corlib4.0-cil \
libmono-system-runtime-serialization-formatters-soap4.0-cil \
libmono-system-web4.0-cil libmono-system-xml4.0-cil \
libmono-system4.0-cil mono-runtime libmono-system-numerics4.0-cil \
libmono-system-data-linq4.0-cil libmono-corlib2.0-cil libmono-system2.0-cil
```

To install the ASN.1 compiler:

```bash
$ cd /opt
$ wget http://download.tuxfamily.org/taste/ASN1SCC/ASN1SCC-latest.tgz
$ tar zxvf ASN1SCC-latest.tgz
$ echo 'export PATH=$PATH:/opt/asn1scc' >> ~/.bashrc
```

Open a new terminal and check that it works:

```bash
$ mono /opt/asn1scc/asn1.exe
```

Optionally, to install llvmpy and LLVM follow the instructions [here](http://www.llvmpy.org/llvmpy-doc/0.12.7/doc/getting_started.html#installation)


OpenGEODE installation
----------------------

Make sure all dependencies are installed.

If you see a certificate error, you may need to run the following commands:

```bash
$ echo -n | openssl s_client -connect gitrepos.estec.esa.int:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > gitrepos.cert
$ sudo cp gitrepos.cert /usr/local/share/ca-certificates/gitrepos.crt
$ sudo update-ca-certificate
```

Then you can get the software with git:

```bash
$ git clone --recursive https://github.com/maxime-esa/opengeode.git
```

And install it:

```bash
$ cd opengeode
$ make install
```

The LLVM backend was designed and implemented by Diego Barbera during the ESA
Summer of Code 2014.
Some parts implemented by Laurent Meyer (native SDL type support in the parser)


The ASN.1 compiler (ASN1Scc) that OpenGEODE is based on was
developed by George Mamais and Thanassis Tsiodras for the European
Space Agency. Information at https://github.com/ttsiodras/asn1scc
