Vulkan.Utils.ShaderQQ.Interpolate

interpExp performs very simple interpolation of Haskell values into Strings.

• Interpolated variables are prefixed with $

• They can optionally be surrounded with braces like ${foo}

• Interpolated variables are converted to strings with show

• To escape a $ use \$

>>> let foo = 123 in $(interpExp "hello, $foo")"hello, 123"

>>> let foo = "world" in $(interpExp "hello, \\$foo")"hello, $foo"

>>> let foo = "world" in $(interpExp "hello\r\n\rworld")"hello\r\n\rworld"
