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}
    {arg1}
    {arg2}
...

{name} {arg1}
    {arg2}
    {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"
    ]]
  ]
]]
