LeanPub Tool — Node.js script for sanitizing and compiling a book's manuscript. LeanPub uses multi-file book format and a special markdown markup (that confuses Marked app). I found that to convert to MS Word (for editing and other needs) this workflow is the best: 1. run leanpub-tool.js with node.js (node leanpub-tool.js) 2. open file in Marked…

leanpub-tool.js

var fs = require('fs');
//change these to YOUR filenames
//probably we can read it from Book.txt but I was too lazy to implement it :-) and somebody might want to compile only sertain parts of the book
var book =[
"frontmatter.txt",
"mainmatter.txt",
"part1.txt",
"chapter1.txt",
"part2.txt",
"chapter2.txt",
"backmatter.txt",
"acknowledgment.txt"
];

var sanitizeText = [
  '{frontmatter}',
  '{backmatter}',
  '{mainmatter}',
  "I>## Note",
  "T>## Tip",
  "W>## Warning",
  '{lang="javascript"}',
  '{:lang="javascript"}',
  '{lang="css"}',
  '{:lang="css"}',
  '{lang="json"}',
  '{lang="ruby"}',
  '{lang="php"}',
  '{lang="text"}',
  '{lang="bash"}',
  '{lang="html"}',
  "I>",
  "T>",
  "W>"
]


var str = '';
//read files
book.forEach(function(chapter){
  str +=  fs.readFileSync(chapter,'utf8');
})
//sanitize LeanPub specific Markdown tags
sanitizeText.forEach(function(text){
//  console.log(text)
  //this loops through while there is not matches
  while (new RegExp (text).test(str)) {
    str = str.replace(text,'','gm')
  };
})

//write output to a file
fs.writeFileSync('leanpub-tool.txt',str);
