Reto: Ficheros INI

The INI file format is an informal standard for configuration files. INI files are simple text files with a basic structure composed of lists of sections, and each section is a list of property-value pairs. The exact rules for this format are as follows:

  • Blank lines and lines starting with semicolons are ignored.

  • Lines wrapped in [ and ] start a new section.

  • Lines containing an alphanumeric identifier followed by an = character add a setting to the current section.

  • Anything else is invalid.

That completely describes the language. Here is an example:

      ; comments are preceded by a semicolon
      ; global section
      searchengine=https://duckduckgo.com/?q=$1
      spitefulness=9.7

      ; each section but the global starts with [identifier]
      [gandalf]
      fullname=Mithrandir
      type=grey wizard
      website=http://tolkiengateway.net/wiki/Gandalf

      [gollum]
      fullname=Sméagol
      type=hobbit
      website=https://lotr.fandom.com/wiki/Gollum

Requirements

  • Our task is to write a node.JS module exporting a function parseINI to convert a INI string into a JavaScript object reflecting the configuration file. For example:

        const parseINI = require('./parse-ini.js');
    console.log(parseINI(`
    name=Torres Quevedo
    [address]
    invention=The chess player`));
    // → {name: "Torres Quevedo", address: {invention: "The chess player"}}

  • Document the parseIni function

  • Write several unit tests using mocha. Here you have an initial template using should but you can use expect if you prefer it.

    var should = require("should");
var parser = require('../lib/parse-ini.js');

describe("parseINI", function() {
  it("should parse a INI input", function() {
    let expected = {name: "Torres Quevedo", address: {invention: "The chess player"}};
    let  result = parseINI(`
    name=Torres Quevedo
    [address]
    invention=The chess player`));
    expected.should.eql(result);
  })
  it("should have an error if not valid", function() {
    (function(){parseINI('chazam')}).should.throw(/Error/);
  })
})

  • Make a web site with your report using GitHub pages and Jekyll (deploy it in the master branch). Remember to set the GitHub repo description and webpage fields
