prop-ini使用教程帮助文档

PropINI

Read, Write, Encode, Decode & Manage INI/Property files with ease.

Install

npm install prop-ini

Usage

1] Require the module in your code

    var PropINI = require("prop-ini");

2] Create new instance for PropINI

    var piTheOne = PropIni.createInstance();

3] Decode/Read data

    var iniData = piTheOne.decode(<config>);

<config> is an object with following props

  • config.data - Pass the INI/Properties format data directly as a string
  • config.file - Tell the function to get the data from this file
  • config.charset - Tell function to read file by this encoding
  • config.lineSeparator - Tell function to split lines based on this char

The returned iniData is an object with following props

  • iniData.sections - Object containing sections as top-level nodes and properties of appropriate sections as child nodes for them. _global is a special section where properties without any section are available
  • iniData.sectionOrder - Array of section names in exact order matching the parsed data. _global will be the first entry

On successfull decode the parsed values will be stored with the PropINI instance as properties. You may access them using piTheOne.sections and piThOne.sectionOrder. Handle with care !

4] Encode/Write data

    var iniString = piTheOne.encode(<config>);

<config> is an object with following props

  • config.sortSections - Sort section names using String.prototype.localeCompare
  • config.sortKeys - Sort properties/keys under each section with localeCompare
  • config.file - Tell function write the encoded data to this file
  • config.charset - Tell function to write file with this encoding
  • config.lineSeparator - Tell function to join lines based on this char

The returned iniString is a string type variable containg INI/Property file format data

Other convenience functions (After parsing data …)

1] Get section names as an Array

    var sections = piTheOne.getSections();
  • sections is an Array containing all sections in the parsed instance data
  • _global is excluded
  • Parsed section order is maintained

2] Get anything you want !

    var data = piTheOne.getData(<section>, <key>);
  • section is the name of the section. In absense of key whole section’s object with child properties will be returned
  • key is the name of the property under some section. In absense of section, _global section will be used. String value of a key will be returned
  • In absense of both section & key, whole data will be returned as an object with sections, sectionOrder as properties

3] Set anything you want !

    var success = piTheOne.addData(<value>, <section>, <key>);
  • section is the name of the section. value should be given as an object in this case
  • key is the name of the property under some section. In absense of section, _global section will be used. value should be of String type in this case
  • In absense of both section & key, you can set the whole data for the instance. An object with sections, sectionOrder as properties should be given for value. sections property should have _global child property.

4] Remove anything you want !

    var success = piTheOne.removeData(<section>, <key>);
  • section is the name of the section. In absense of key whole section will be removed.
  • key is the name of the property under some section. In absense of section, _global section will be used.
  • In absense of both section & key, whole instance data will be reset to empty state.
And, one more thing …
  • Since the data is exposed as instance properties you can directly process them as you wish. But please respect the format PropINI expects the data to be in.
  • piTheOne.sections should always be an object
  • piTheOne.sectionOrder should always be an array and should be in sync with piTheOne.sections data
  • piTheOne.sections should always have a child object _global
