Usage

Clone this project with --depth 1
Edit myhtml_ strtucture in hello.hs
Compile the hello.hs with ghc hello.hs
Or you can write your own main.hs and use built-in render function
Run the binary file you compiled, and redirect the std output to a new file

Shell command

./hello > hello.html

Example Input

html = html_
