SHMAML

Parse .ini files into JSON objects. Support lists.

Install

$ npm install shmaml

Use

const parse = require('shmaml');

const resultPromise = parse('../path/to/config.ini');
// or:
const result = parse.sync('../path/to/config.ini');

 

Example config.ini + list:

username = me
pasword = 1234

[SectionA]
  key=value

[SectionB]
  key=value
  list=[
      item1,
      item2,
      item3
  ]

Becomes:

result = {
  username: 'me',
  pasword: 1234,
  SectionA: {
    key: 'value',
  },
  SectionB: {
    key: 'value',
    list: ['item1', 'item2', 'item3']
  },
}

Convention

• key-value pairs are noted with an equal sign.

  key="value"

• Quoting values is optional. Strings are used as default.

  ; These are all the same:
  key=value
  key='value'
  key="value"

• Unquoted numbers are parsed as numbers. Use single/double quotes to make number values parsed as strings.

  number = 55
  string = '55'
  string = "55"

• Unquoted booleans are parsed as booleans. Use single/double quotes to make boolean values parsed as strings. CaSe InSeNsITiVe.

  bool = TRUE
  bool = false
  string = 'true'
  string = "false"

• Sections are noted with wrapping square brackets.

  [categoryA]
      key="value"
  [categoryB]
      key="value"

• Lists are also noted with wrapping square brackets when come after a key=.

  [categoryA]
      key="value"
      list=[item1, item2, item3]

• Multiline lists are also supported.

  [categoryA]
      multilineList=[
          item1,
          item2,
          item3
      ]
      key="value"

NOTE: Nested lists are NOT supported.
list=[A, [B, [C, D]], E]

• Comments are ignored, obviously. Use quotes to work with semicolons:

  ; line comment
  [category]
      key1=value1 ; inline comment
      key2='quoted ; semicolon'
      key3="double quoted ; semicolon"

• Whitespace (including tabs) is trimmed:

  ;Same
  [sectionA]
  [ sectionA ]

  ;Same
  key= value
  key =value
  key  =  value

  [sectionA]
  key=value
  
  ;Same as
  
  [sectionA]
      key=value   

• Preserve whitespace using quotes:

  [' section   ']
  key="  value "

  {
      " section   ": {
          key: "  value "
      }
  }

• Duplicates.
  Duplicated section names are merged to the same object.

  [sectionA]
      key1=value1
  [sectionA]
      key2=value2

  result = {
      SectionA: {
          key1: 'value1',
          key2: 'value2',
      },
  }

  Duplicated key names in the same section: the later overwrites the former.

  sameKey=value1
  sameKey=value2
  sameKey=value3

  result = {
      sameKey: 'value3'
  }
