Parser

Once you have defined the behavior of your parser using the DSL, you can use it:

parser = SuperheroesParser.new
result = parser.run("/some_path/superhero.xls"); #=> #<Enumerator: ...>
row = result.next

Useful methods

In parser/file context:

• parser.valid_file?: returns true if some file validation fails.
• parser.file_error: returns a symbol with the error name if some file validation fails.
• parser.run(file_path): it starts the parsing.

In row context:

• row.idx: the row number matching the xls/csv file.
• row.errors?: returns true if some row's attribute has errors.
• row.errors: returns a hash with errors with the format: { column1: :error_name, column2: :error_name }
• row.attribute_error?(:some_attribute_name): returns true if the given attribute has errors on that row.
• row.add_attribute(:some_attribute_name): to add a custom getter/setter with a custom value.
• row.publisher: having a column(:publisher, name: "Publisher"). Parxer will generate a getter/setter for each column defined with the DSL.
