Lua scriptable SVG image generator

lsvg is a Lua interpreter specialized to generate SVG images.

It is based on LuaX and uses a pure Lua library to generate SVG images. It optionally requires ImageMagick to make PNG, JPEG or PDF images.

lsvg was initially inspired by svg-lua.

Installation

lsvg is available on Github: https://github.com/CDSoft/lsvg.

lsvg uses LuaX.

$ git clone https://github.com/CDSoft/luax && ninja -C luax install
$ git clone https://github.com/CDSoft/lsvg
$ cd lsvg
$ ninja install

If LuaX is not installed yet, the first compilation may take a while…

Precompiled LuaX binaries

In case precompiled binaries are needed (GNU/Linux, MacOS, Windows), some can be found at cdelord.fr/hey. These archives contain lsvg as well as some other softwares more or less related to LuaX.
