• Go

• go get
• go build

Running go build will result in a binary named waitress being created. This can then be moved to the /usr/local or the preferred install path.

Usage of waitress: -binding="0.0.0.0": bind the server to the specified ip -config="": conf file (see config.yml.sample) -port="3000": run the server on the specified port

The format is specified as the first part of the URL path. The syntax is similar to the geometry syntax of ImageMagick.

s ::= ( width | 'x' height | width 'x' height ) ( '#' | '^' | '!' )?
bg ::= (
    '#' [0-9A-Fa-f]{6} |
    'rgb(' \d{1,3} ',' \d{1,3} ',' \d{1,3} ')' |
    'rgba(' \d{1,3} ',' \d{1,3} ',' \d{1,3} ',' \d+ (\.\d+)? ')' |
    'hsl(' \d{1,3} ',' \d{1,3} '%,' \d{1,3} '%)' |
    'hsla(' \d{1,3} ',' \d{1,3} '%,' \d{1,3} '%,' \d+ (\.\d+)? ')'        
)

s=700: Resize the image to have a width of 700 (maintains aspect ratio) s=x700: Resize the image to have a height of 700 (maintains aspect ratio) s=700x700: Resize the image to have a width and height of 700. This maintains the aspect ratio and pads image with a background color.
