hackfile

hackfile

Parser for the hackfile format

npm install hackfile

Format

The hackfile format is similar to a Makefile. There are two accepted formats:

{name}
(indent){arg1}
(indent){arg2}
...

{name} {arg1}
(indent){arg2}
(indent){arg3}
...

hackfiles can also be nested:

{name} {arg}
(indent){name} {arg}
(indent)(indent){arg}
(indent){arg}
...

Usage

Assuming you have a hackfile that looks like this

foo bar

bar echo c
  echo d

bat
  echo e
  echo f
  echo g

baz echo a b c d

The following example

var hackfile = require('hackfile')
var fs = require('fs')

var parsed = hackfile(fs.readFileSync('hackfile', 'utf-8'))
console.log(parsed)

Prints out

[ [ 'foo', [ 'bar' ] ],
  [ 'bar', [ 'echo c', 'echo d' ] ],
  [ 'bat', [ 'echo e', 'echo f', 'echo g' ] ],
  [ 'baz', [ 'echo a b c d' ] ] ]

Nested Example

hackfile input:

pipeline foo
  pipe
    echo hello
    transform
    cat
  run echo
    hello

parser output:

[['pipeline', 
  ['foo', 
    ['pipe', 
      ['echo hello', 'transform', 'cat']
    ], 
    ['run', 
      ['echo', 'hello']
    ]
  ]
]]
