## A very silly little example to create bionic reading html documents
## from a text document.
## needs the markdown-package from nimble:
##
## $ nimble install markdown
##

import
  markdown,
  std/os,
  std/strutils

proc printUsage() =
  echo "Usage"
  echo "====="
  echo "bionic [filename]"
  echo "echos bionic html generated from the input text"

proc bionify(text: string): string =
  for word in text.split():
    if word.len == 0:
      continue
    if word.len == 1:
      result &= "**"
      result &= word
      result &= "** "
      continue
    let half = word.len div 2
    result &= "**"
    result &= word[0..half - 1]
    result &= "**"
    result &= word[half..word.len - 1]
    result &= " "


if paramCount() != 1:
  printUsage()

let filename = paramStr(1)
let filedata = readFile(filename)
let mdText = bionify(filedata)
let html = markdown(mdText)
let oFileName = filename.split('.')[0] & ".html"
writeFile(oFileName, html)
