# Lire
*"Maybe if lisp started today, we would a syntax of lisp look like trees"* -- **Hal Abelson** ([1986 lecture](https://www.youtube.com/watch?v=XYKRVNQ_MqE&feature=youtu.be&t=34m33s))
## In short
Lire is a Lisp expressions visual editor, it allows you to write programs using kind of [abstract syntax tree (AST)](https://en.wikipedia.org/wiki/Abstract_syntax_tree). It runs on top of Common Lisp.
Lire is work in progress project. It is also my diploma thesis.
## Modeling list
Try to enter
```+ Enter 10 Enter * Enter Enter 25 Enter 2```
This will make list
```(+ 10 (* 25 2))```
## Try it out!
Check the [releases page](https://github.com/honix/Lire/releases). There is ready to go Windows executable, as it is little hard to build on this system.
## Run from source
Lire is well tested to work with [SBCL](http://www.sbcl.org). Before run Lire check that you dependencies ready:
**Linux (x86 and x64)**
- Ubuntu (apt-get): ```sudo apt-get install libffi6 libffi-dev libsdl2 libsdl2-image libsdl2-ttf```
- Fedora (dnf): ```sudo dnf install libffi libffi-devel SDL2 SDL2_image SDL2_ttf```
- ArchLinux (pacman): ```sudo pacman -S libffi sdl2 sdl2_ttf sdl2_image```
**Windows (x86)**
- Install [MinGW](https://sourceforge.net/projects/mingw/files/Installer) with ```mingw32-base``` package, and copy ```ffi.h``` and ```ffitarget.h``` from ```deps/windows``` to ```...\MinGW\include```
- Add ```...\MinGW\bin``` to the PATH environment variable (make able Common Lisp to call ```gcc```)
- Put the dll's to your SBCL folder, right with ```sbcl.exe``` (for x86 there is collected already, check ```deps/windows```)
**Lets go**
```cd your/path/to/Lire``` *and* ```sbcl --load lire.lisp```
