Changelog

Version 0.8.2

  • Add type hints to CleverCSV
  • Disable 32-bit builds on Windows and Linux
  • Bump minimal Python version to 3.8
  • Minor documentation improvements

Version 0.8.0

  • Improve median runtime by ~68% (~52% on average) by: 1) more caching, 2) implementing a heavy function in C.
  • Redesign computation of consistency measure to a class: ConsistencyDetector.
  • Fix potential memory leak in C code for base abstraction
  • Fixes to escape sequences in regexes (thanks to @JakobGM!)

  • Add support for Python 3.11 by fixing a bug regarding empty strings in dialects (thanks to @stefanor!)
  • Fix installation error due to change in internals at setuptools (thanks to @mweinelt!)
  • Migrate to faust-cchardet as cChardet fails to install on Python 3.11 (on Windows, currently only chardet will work for Python 3.11)
  • Migrate to packaging for version comparison

Version 0.7.4

  • Add wrapper for writing a list of dictionaries (write_dicts)
  • Fix bug when writing CSVs using the csv module dialects
  • Add the builtin dialects to CleverCSV (e.g., clevercsv.excel)

Version 0.7.3

  • Release to build wheels for Python 3.10

Version 0.7.2

  • Re-implement command line interface using Wilderness
  • Add man-pages to package

Version 0.7.1

  • Remove deprecated wrapper functions
  • Expand URL regex to support localhost:<port> urls
  • Minor changes to the TypeDetector API
  • Add cChardet as optional dependency (fixes #48)

Version 0.7.0

  • Add a JSON object data type to address a specific failure case (#37).
  • Add support for timezones for time data type
  • Add support for building wheels on non-native architectures (#39).
  • Add a flag to disable skipping type detection using the command line interface.

Version 0.6.8

  • Add a "bytearray" type to address a specific failure case (#35).
  • Minor clarifications to licensing.

Version 0.6.7

  • Updates to release process. This version introduces pre-compiled wheels for Python 3.9.

Version 0.6.6

  • Add an encoding argument to write_table to allow specifying the output encoding. Thanks to @mitchgrogg for reporting issue #27.

Version 0.6.5

  • Add support for standardizing in-place and standardizing multiple files.
  • Add warning on duplicate field names in DictReader
  • Add return value to writers to match the standard library.

Version 0.6.4

  • Various speed ups to constructing the list of potential dialects. This removes a costly step of the detection process that will likely add a few more potential dialects, but has the end result of making overall dialect detection faster.

Version 0.6.3

  • Rename wrapper functions to a more coherent naming scheme. Old names will be available until 0.7.0, but now produce a FutureWarning.
  • Add stream_dicts wrapper function.
  • Improve handling of file encoding for the read_dataframe wrapper: detected encoding is now passed on to Pandas.
  • Fix handling of optional dependency error for TabView on non-Windows platforms.

Version 0.6.2

  • Update URL regex to avoid catastrophic backtracking and increase performance. See issue #13 and issue #15. Thanks to @kaskawu for the fix and @jlumbroso for re-raising the issue.
  • Add num_chars keyword argument to read_as_dicts and csv2df wrappers.
  • Improve documentation w.r.t. handling large files. Thanks to @jlumbroso for raising this issue.

Version 0.6.1

  • Add an explore command to the command line application for CleverCSV. This command makes it easy to start exploring a CSV file using the Python interactive shell.

Version 0.6.0

  • Split the package into a "core" and "full" version. This allows users who only need the improved dialect detection functionality to download a version with a smaller footprint. Fixes issue #10]. Thanks to @seperman.

Version 0.5.6

  • Fix speed of unix_path regex used in type detection. (issue #13). Thanks to @kaskawu.
