parse-css-color-components clj/s

(parse-css-color-components css-str)

Parse CSS rgb() or rgba() string into color component vector.

Takes a CSS color string and normalizes it internally before extracting the color components using regex matching. Handles various formatting variations including different spacing and case.

Args: css-str - A CSS color string in format: - 'rgb(r,g,b)' or 'rgb(r g b)' - 'rgba(r,g,b,a)' or 'rgba(r g b a)' - Case insensitive, flexible whitespace

Returns:

• For rgb(): [r g b] where r, g, b are integers 0-255
• For rgba(): [r g b a] where r, g, b are integers 0-255 and a is float 0.0-1.0
• nil if the string doesn't match expected format or values are out of range

Examples: (parse-css-color-components "rgb(255,0,0)") => [255 0 0] (parse-css-color-components "RGB( 255 , 0 , 0 )") => [255 0 0] (parse-css-color-components "rgba(255,0,0,0.5)") => [255 0 0 0.5] (parse-css-color-components "rgb(256,0,0)") => nil (out of range)
