Lire

“Maybe if lisp started today, we would a syntax of lisp look like trees” — Hal Abelson (1986 lecture)

In short

Lire is a Lisp expressions visual editor, it allows you to write programs using kind of abstract syntax tree (AST). 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. 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. 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 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
