Usage

Pass the transform implementation to mktransform:

var highlight = require('mkhighlight')
  , ast = require('mkast')
  , tfm = require('mktransform');

ast.src('```javascript\nvar foo = "bar"\n```')
  .pipe(tfm(highlight))
  .pipe(ast.stringify({indent: 2}))
  .pipe(process.stdout);

Example

To highlight code blocks in a document with ANSI escape sequences:

mkcat README.md | mkhigh -o esc | mkout

To highlight code blocks for a standalone HTML page:

mkcat README.md | mkhigh | mkpage | mkhtml > README.html

Number lines in the code blocks:

mkcat README.md | mkhigh --lines | mkpage | mkhtml > README.html
