Feed it input through stdin. By default the program calculator std140 layout, the --std430 flag switches it to std430.
Example input (similar to glsl):

vec3 position
float rotation
vec2 scale
float texu
float texv
float texw
float texh
vec4 color

or with explicit blocks

#struct light
vec4 position
float strength
float parameters[3]

#uniform main
mat4 view
light lights[32]

• Input

• Array of structs

• Parse structures

• flag for std140 vs 430

• big refactor

• display errors and struct end padding

• don't leak memory and don't persist structs

• Output improvements (color, nested outputs, array elements)

• "storage" block with allowed unsized array at end

• switch to blocks defined by double newline, and error if no data instead of probably breaking

• web version

• improve web version (automatically run)

• add web version to my site

• blog post
