SmarterCSV 1.x Change Log

1.6.1 (2022-05-06)

  • unused keys in key_mapping now generate a warning, no longer raise an exception This is preferable when key_mapping is done defensively for variabilities in the CSV files.

1.6.0 (2022-05-03)

  • completely rewrote line parser
  • added methods SmarterCSV.raw_headers and SmarterCSV.headers to allow easy examination of how the headers are processed.

1.5.2 (2022-04-29)

  • added missing keys to the SmarterCSV::KeyMappingError exception message #189 (thanks to John Dell)

1.5.1 (2022-04-27)

  • added raising of KeyMappingError if key_mapping refers to a non-existent key
  • added option duplicate_header_suffix (thanks to Skye Shaw) When given a non-nil string, it uses the suffix to append numbering 2..n to duplicate headers. If your code will need to process arbitrary CSV files, please set duplicate_header_suffix.

1.5.0 (2022-04-25)

  • fixed bug with trailing col_sep characters, introduced in 1.4.0

  • Fix deprecation warning in Ruby 3.0.3 / $INPUT_RECORD_SEPARATOR (thanks to Joel Fouse )

  • changed default for comment_regexp to be nil for a safer default behavior (thanks to David Lazar) Note This no longer assumes that lines starting with # are comments. If you want to treat lines starting with '#' as comments, use comment_regexp: /\A#/

1.4.2 (2022-02-12)

  • fixed issue with simplecov

1.4.1 (2022-02-12) (PULLED)

  • minor fix: also support col_sep: :auto

  • fixed buggy behavior when using remove_empty_values: false (issue #168)
  • fixed Ruby 3.0 deprecation

1.3.0 (2022-02-06) Breaking code change if you used --key_mappings

  • fix bug for key_mappings (issue #181)
    The values of the key_mappings hash will now be used "as is", and no longer forced to be symbols

    Users with existing code with --key_mappings need to change their code to

    • either use symbols in the key_mapping hash
    • or change the expected keys from symbols to strings

  • fix bug for key_mappings (issue #181) The values of the key_mappings hash will now be used "as is", and no longer forced to be symbols
