csvjson library / gem v1.0 - read tabular data in the CSV <3 JSON format, that is, comma-separated values CSV (line-by-line) records with JSON encoding rules

Hello,

  I've published a new library / gem, that is, csvjon that lets you
read tabular data in the (new) CSV <3 JSON format, that is,
comma-separated values CSV (line-by-line) records with javascript
object notation (JSON) encoding rules.

   What's CSV <3 JSON?

CSV <3 JSON is a Comma-Separated Values (CSV)
variant / format / dialect
where the line-by-line records follow the
JavaScript Object Notation (JSON) encoding rules.
It's a modern (simple) tabular data format that
includes arrays, numbers, booleans, nulls, nested structures, comments and more.
Example:

    # "Vanilla" CSV <3 JSON

    1,"John","12 Totem Rd. Aspen",true
    2,"Bob",null,false
    3,"Sue","Bigsby, 345 Carnival, WA 23009",false

or

    # CSV <3 JSON with array values

    1,"directions",["north","south","east","west"]
    2,"colors",["red","green","blue"]
    3,"drinks",["soda","water","tea","coffe"]
    4,"spells",[]

  And how to read / parse in ruby? Example:

  txt <<=TXT
  # "Vanilla" CSV <3 JSON

  1,"John","12 Totem Rd. Aspen",true
  2,"Bob",null,false
  3,"Sue","Bigsby, 345 Carnival, WA 23009",false
  TXT

  records = CsvJson.parse( txt ) ## or CSV_JSON.parse or CSVJSON.parse
  pp records
  # => [[1,"John","12 Totem Rd. Aspen",true],
  # [2,"Bob",nil,false],
  # [3,"Sue","Bigsby, 345 Carnival, WA 23009",false]]

  # -or-

  records = CsvJson.read( "values.json.csv" ) ## or CSV_JSON.read or
CSVJSON.read
  pp records
  # => [[1,"John","12 Totem Rd. Aspen",true],
  # [2,"Bob",nil,false],
  # [3,"Sue","Bigsby, 345 Carnival, WA 23009",false]]

  # -or-

  CsvJson.foreach( "values.json.csv" ) do |rec| ## or
CSV_JSON.foreach or CSVJSON.foreach
    pp rec
  end
  # => [1,"John","12 Totem Rd. Aspen",true]
  # => [2,"Bob",nil,false]
  # => [3,"Sue","Bigsby, 345 Carnival, WA 23009",false]

  and so on.

   Happy data wrangling with ruby (and csv and json). Cheers. Prost.

Didn't even know the csvjson format existed. I'm sure this will come in handy in the future.

Had a quick glance at the code. Looks like this thing won't explode memory wise when trying to read a huge csv file as long as you stick to the foreach method.

Anyway, thanks thanks thanks for this gem.

Cheers,

Ivo
