csv-hash¶ ↑

Will import a CSV as an array of hashes. Or will export a CSV from an array of hashes (if given a column list).

Usage¶ ↑

Parse a csv to an array of hashes¶ ↑

array_of_hashes, columns = CSVHash('path_to_csv.csv')

Note the hash will have strings for keys and will remove all surrounding whitespace

Generate a string from an array of hashes and a column list¶ ↑

string = CSVHash(array_of_hashes,[:column,"names","in",:order])

Nested Hashes¶ ↑

csv-hash supports nested hashes. A column tree of the structure (note the double underscore):

one,two__foo,two__bar__three,two__bar__four
 1,    2,          3,              4,

will generate:

{
  'one' => '1',
  'two' => {
    'foo' => '2',
    'bar' => {'three' => '3', 'four' => '4'}
  }
}

Todo¶ ↑

• Remove dependency on Fast CSV

• Support auto column generation

• Generate hash of arrays

• Turn into CSVHash object which contains column structure and other metadata

• Sequel integration

• Arbitrary model support

Note on Patches/Pull Requests¶ ↑

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
