svg-lua#

svg lua library (made for LUA 5.3.4)

usage#

mon_dessin = svg:create()
mon_dessin:add(mon_dessin:Rect())
mon_dessin:draw()

result for print(mon_dessin:draw()) :

<svg width="100" height="100" fill="transparent" stroke="#000000" version="1.1" xmlns="http://www.w3.org/2000/svg">
    <rect y="10" x="10" stroke-width="1" height="10" width="10" rx="0" ry="0" />
</svg>

testing#

can be tested here

to test using the binaries included in the project:

open a command prompt un the subdirectory lua5.3.4-win64 (Shift+Right Click on Windows)
type lua53.exe ..\test.lua

If you want to save the output in a file to see the result you can add > result.svg or >> result.svg following the previous command to save the result in an html file:

lua53.exe ..\test.lua > result.svg: this will create a file result.svg in the directory with the resul, replacing the file if already exists this can be done using test.bat.
lua53.exe ..\test.lua >> result.svg: this will create a file result.svg in the directory with the resul, appending result to the existing file if already exists.

If you are using a custom test file, replace test.lua by your file name.
