IMMO SQUARE Extensions

Enhance your Ruby experience with utility methods for standard classes like String, Array, and Hash.

Add this line to your application's Gemfile:

gem 'immosquare-extensions'

Then execute:

$ bundle install

Or install it yourself:

$ gem install immosquare-extensions

.to_boolean (Convert strings like "true" and "false" to their boolean counterparts.)

"true".to_boolean   # => true
"false".to_boolean  # => false
"string".to_boolean # => nil

.titleize_custom (Titleize strings while preserving hyphens, ideal for city names.)

"SANT-ANDREA-D'ORCINO".titleize_custom  # => "Sant-Andrea-D'orcino"

.upcase (Upcase strings with proper Unicode handling.)

"ä".upcase  # => "Ä"

.mean (Compute the average of numerical arrays.)

[1, 2, 3, 4, 5].mean   # => 3.0

.without (Remove multiple keys in one command.)

{a: 1, b: 2, c: 3}.without(:a, :b)  # => {:c=>3}

.depth (Determine the depth of a nested hash.)

{a: {b: {c: 1}}}.depth  # => 3

.sort_by_key (Sort a hash by its keys, and optionally sort nested hashes recursively.)

{b: 1, a: {d: 4, c: 3}}.sort_by_key  # => {:a=>{:c=>3, :d=>4}, :b=>1}
{b: 1, a: {d: 4, c: 3}}.sort_by_key(:recursive => false)  # => {:a=>{:d=>4, :c=>3}, :b=>1}

.flatten_hash (Flatten nested hashes into a single-level hash with dot notation.)

{a: {b: {c: 1}}}.flatten_hash  # => {:a.b.c=>1}

...

.to_beautiful_json (Render the hash into a beautifully formatted JSON string, with options for alignment and indentation.)

Options:

• :align (default is true): Aligns the colons in key-value pairs for better readability.

• :indent_size (default is 2): Specifies the number of spaces for each indentation level.

Example:

hash_example = {
  name: "John",
  age: 30,
  address: {
    street: "123 Apple St",
    city: "FruitVille",
    postal_code: "12345"
  },
  is_student: false,
  courses: ["Math", "Science"]
}

puts hash_example.to_beautiful_json

Output:

{
  "name":       "John",
  "age":        30,
  "address":    {
    "street":      "123 Apple St",
    "city":        "FruitVille",
    "postal_code": "12345"
  },
  "is_student": false,
  "courses":    [
    "Math",
    "Science"
  ]
}

Disabling Alignment:

puts hash_example.to_beautiful_json(align: false)

Output:

{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Apple St",
    "city": "FruitVille",
    "postal_code": "12345"
  },
  "is_student": false,
  "courses": [
    "Math",
    "Science"
  ]
}

Ensures that a file ends with a single newline character, facilitating cleaner multi-line blocks.

total_lines = File.normalize_last_line('path/to/your/file.csv')
puts "Total lines in the normalized file: #{total_lines}"
