First stage: file smile.txt

 

The All-American Smile In a way he was like the land itself. Everything came to him too easily. But at least he knew it, and from time to time he worried about being a phoney.

 

Write a single expression that reads the file, follows Markdown rules, and returns an HTML document as a string, e.g.

 

  
     
The All-American Smile

Hints: The .h namespace and File Binary; however .h.ht is not a solution.

Not tempted yet? Lets make it easier and harder.

  • Easier: file lines have no trailing spaces.
  • Harder: let your expression contain no more than one reference to .h.htc.

{.h.htc[y;x]}/[.h.text"nn"vs"c"$ read1 `:smile.md;`body`html]
