Array-Of-Hashes

Array Of Hashes algorithm in Ruby

Something I made to act as a simple database for my ComicMan project. TODO is making a documentation for it, but chances are there are far better libraries out there anyways.

Usage:

When starting out with no database, you can stil use AOH.load!(...), or: DB = AOH.new()

or

To create an instance of the database that runs in memory (with the hash data), of course. If no args are specified, an empty aoh database is created: DB = AOH.new(<hashes, separated by commas; optional>)

or

DB = AOH.new()

Load an existing database file, or create one at that location (when you save): DB = AOH.load!(file_location: "/your/file/here.db") #Loads here.db, and will create a new database file if one doesn't exist

Saves the database to specified location: AOH.save!(file_location: "/your/file/here.db")

Returns the hash data of the integer id array indice
data_hash = DB.get_id(integer)

Set an existing ID in DB with some data

DB.set_id(integer) do |config|
  config[:some_hash] = "some string"
  # ...
  config[:some_other_hash] = 42
 end
 

Add to the database:

Append to the end of the array all hash data speficied in args

 DB.add(data_hash1: "data", ..., data_hashN: "dataN", data_hashInt: 42)
 DB.reverse_add(...) #=> identical to above, but sets id to be the first in the array

Save the database DB.save!(file_location: "/your/file/here.db")

And to remove an indice: DB.rem_by_id(integer_id)

Get an id in the database, or returns nil data_hash = DB.get_id(id)
