Changes

1.6.2 -- 2024-mm-dd

  • Fixed packaging: include man page, source distribution did not contain all relevant files such as docs and test suite.

1.6.1 -- 2024-02-08

  • Switched from setuptools to flit for setup
  • Updated test suite to work with musl based distributions

1.6.0 -- 2023-11-28

  • Dropped Python 2.7 support
  • Removed dependency on pkg_resources. Segno uses importlib.metadata to provide plugins. For Python versions < 3.10 this introduces a dependency on importlib-metadata.

1.5.3 -- 2023-10-25

  • Merged PR #124 implemented by missionfloyd: Remove the trailing dot of latitude/longitude information.
  • Merged PR #125 implemented by missionfloyd: More lenient check how to interpret empty or false values in vCard and MeCard.
  • Internal changes: Made writers module independent of internal version constants, they operate upon a matrix of a given size and know nothing about the QR Code version (i.e. QR Code vs. Micro QR Code). These changes are backwards incompatible but the writers module does not belong to the public API anyway.
  • Dropped testing against PyPy2
  • Changed default Python test version to 3.11 (2.7 is still supported)
  • Support for Python 2.7 will be dropped in the next version of Segno because it is no longer possible to run automatic tests against Python 2.x.
  • Removed deprecated statements from setup.cfg (#127 thanks for the hint, Gene)
  • Updated example to Pillow 10 API (#128, again thanks to Gene)

1.5.2 -- 2022-05-25

  • Added support for PEP 517

  • Removed PyQRCode from comparison / benchmarks since it adds no value anymore

  • Added more properties for vCard see PR #106 contributed by Tobias Udtke:

    • cellphone (TEL;TYPE=CELL)
    • homephone (TEL;TYPE=HOME)
    • workphone (TEL;TYPE=WORK)

    Signatures of segno.helpers.make_vcard and segno.helpers.make_vcard_data changed, but in a backwards compatible way.

  • Changed default Python test version to 3.10 (2.7 and above are still supported)

1.5.1 -- 2022-05-24

  • Unreleased due to packaging failures.

1.5.0 -- 2022-05-24

  • Unreleased due to packaging failures.

1.4.1 -- 2021-11-25

  • Fixed Python type hints
  • XPM serializer accepts None (transparent) for dark modules
  • Better docs

1.4.0 -- 2021-11-06

  • Added option to print QR codes in a more compact manner to the terminal. PR #97 implemented by Christian Oudard.
  • Minor doc changes
  • Added more test cases
  • Updated benchmark results

1.3.3 -- 2021-03-23

  • Fixed #95: helpers.make_wifi and helpers.make_wifi_data may return invalid data if any input contains characters which can be interpreted as an integer.
  • Updated helpers.make_wifi and helpers.make_wifi_data signature and doc strings to match the stub / type hints.

1.3.2 -- 2021-03-22

  • Not released due to twine issues (markup errors in README.rst)

1.3.1 -- 2020-09-01

  • Fixed: Stub files (type hints) were missing from the source distribution.

1.3.0 -- 2020-08-31

  • Fixed #84: CLI --encoding was used for the encoding of SVG documents and not for the encoding of the QR code. Added --svgencoding to specify the encoding of SVG documents.

1.2.1 -- 2020-08-27

  • Improved API docs
  • Added support for type hints for the public API (stub files)

1.2.0 -- 2020-08-18

  • Added QRCode.svg_inline method which returns a string which can be used to embed the SVG directly in HTML pages.
  • Improved documentation <https://segno.readthedocs.org/>
  • Improved code quality
  • Switched from tox to nox
  • Utilize flake8
  • Moved metadata from setup.py to setup.cfg

1.1.0 -- 2020-08-05

1.0.2 -- 2020-07-30

  • Fixed error in Kanji encoding: Data was incomplete. Again, discovered by Shi Yan
  • Better test coverage for Kanji encoding

1.0.1 -- 2020-07-28

  • Fixed wrong information about character count in Kanji mode (discovered and fixed by Shi Yan)
  • Fixed #72: Encodings for helpers.make_epc_qr may be specified by name or by a numeric constant.
  • Added support for Netpbm PPM images.
  • Documentation improvements (also thanks to James Addison for pr #73)
  • Removed "version" parameter from encoder.prepare_data (does not belong to the public API anyway)

1.0.0 -- 2020-02-14

  • Removed support for color / background keywords (deprecated in 0.4.0). Use dark and light.
  • Reintroduced segno.DataOverflowError (inherited from ValueError) to indicate that the provided data does not fit into the provided (Micro) QR Code parameters.
  • Documentation improvements
  • Although this lib made backwards incompatible changes since version 0.1.0, the changes should be clear since almost all changes were made very conservative with backwards compatibility in mind. Even early adopters should find a clear update path. This version marks a stable API acc. to Semantic Versioning.
  • The initial stable release after nearly four years of development. Happy valentine ;)

0.4.0 -- 2020-01-21

  • Removed deprecated functions, modules etc. See #56, #57, #59, #61, #67.
  • Deprecated usage of keywords "color" and "background". Replacements: "dark" and "light". See #60. The deprecated keywords will be removed in 1.0.0.
  • Minor performance improvements for writing SVG (at least for Py 3.7, YMMV).
  • Documentation improvements

0.3.9 -- 2020-01-19

  • Fixed #71: Dark / light modules of the finder pattern may be interpreted wrong if set to None
  • Removed segno.encoder, segno.writers and segno.utils from public API (fixes #69)
  • Removed segno.colors (part of segno.writers now)
  • Documentation improvements

0.3.8 -- 2020-01-15

  • Added support for multiple (more than two) colors to SVG (fixes #64)
  • Fixed several test cases
  • Removed QRCodeError and all derived exceptions from public API (still available but not thrown and they will be removed in 0.4.0)
  • Documentation improvements

0.3.7 -- 2020-01-09

  • Documentation improvements: Added several examples, fixed docs
  • Fixed #62: PNG serializer adds only those colors to the PLTE which are actually needed for the given (Micro) QR Code.
  • Minor performance improvements

0.3.6 -- 2020-01-06

  • Backwards incompatibility change: QRCode.show() uses "dark" instead of "color" and "light" instead of "background" to define the color of the dark / light modules

  • Backwards incompatibility change: All segno.writers use "dark" instead of "color" and "light" instead of "background". This does not affect normal users, but only users of the low level API.

  • Changed the keyword for setting the color of the dark modules from "color" to "dark" and for setting the light modules from "background" to "light" The former keywords are still supported. Their usage will issue a DeprecationWarning in the future.

  • Added --dark and --light to the command line interface, see point above. `--color` and --background are still supported.

  • Fixed typos, improved documentation

  • Deprecated segno.moduletypes (will be removed in release 0.4.0), moved all constants to segno.consts

  • Deprecated usage of parameter "colormap" (introduced in 0.3.4). It still works but a deprecation warning is issued. Instead of:

    colormap = {mt.TYPE_FINDER_PATTERN_DARK: 'darkred',
            mt.TYPE_ALIGNMENT_PATTERN_DARK: 'darkred',
            mt.TYPE_TIMING_DARK: 'darkred',
            mt.TYPE_DARKMODULE: 'darkred',
            mt.TYPE_DATA_DARK: 'darkorange',
            mt.TYPE_DATA_LIGHT: 'yellow',
            mt.TYPE_FORMAT_DARK: 'darkred'}

qr.save('qrcode.png', scale=5, colormap=colormap)

    use:

    qr.save('qrcode.png', scale=5, dark='darkred', data_dark='darkorange',
        data_light='yellow')

    See Colorful QR Codes for a description of available module names.

  • Fixed issue #54: After last change (see 0.3.3), white background with transparent QR Code did not work. Enhanced test suite to cover all possible inputs for PNG grayscale mode
  • Removed interpretation of addad from PNG serializer. Contradicts the claim to create small images by default. It still belongs to the function signature but will be removed in release 0.4.0
  • The option --no-ad (CLI) is still available but ignored and will be removed in release 0.4.0. Removed the option from man page.
  • Added option to PNG serializer to provide more than two colors. Each module type may have its own color.

  • Removed test environments CPython 3.4 and 3.6 from tox
  • Improved documentation
  • Refactored source code
  • Added test cases
  • Fixed bugs in helpers.make_vcard_data function (superfluous semicolon in birthday line, check geo coordinates)
  • Renamed utils.matrix_iter_detail into utils.matrix_iter_verbose. Kept matrix_iter_detail for backwards compatibility (deprecated, will be removed in release 0.4.0)
  • Moved module constants from segno.utils into segno.moduletypes, Constants from segno.utils will be removed in release 0.4.0.
  • Added option verbose (default: False) to segno.QRCode.matrix_iter() which returns an iterator which provides information about the module type (i.e. quiet zone, dark data module, light data module).

0.3.2 -- 2019-07-15

0.3.1 -- 2019-07-15

  • See 0.3.2

0.3.0 -- 2019-06-25

  • Added -s shortcut to Segno's command line interface to provide the scaling factor
  • Added -b shortcut to Segno's command line interface to provide the border / quiet zone
  • CLI accepts unquoted, whitespace separated content: segno "Comfortably Numb" can be written as segno Comfortably Numb

0.2.4 -- 2017-01-31

  • Fixed #33: Some Micro QR Codes may be unreadable due to wrong format information. Further, M1 and M3 codes may be wrong due to wrong encoding of final data symbol character (8 bits instead of (correct) 4 bits). Thanks to Nicolas Boullis for the bug report, initial fix, tests and patience.
  • Fixed #34: Change default error level from "M" to "L" to avoid surprises that the content does not fit into the provided version. This change is somewhat backwards incompatible.

0.2.3 -- 2016-10-17

  • Fixed #27: Email URI is wrong if CC or BCC is used.
  • Fixed #32: Don't add version attribute if SVG >= 2.0
  • Deprecated writers.get_writable; use writers.writable writers.writable closes file-like objects automatically (if necessary); replace writable, must_close = writers.get_writable(filename_or_buffer, mode) with with writers.writable(filename_or_buffer, mode) as f
  • Added option to PNG serializer to specify an optional DPI value (thanks to Markus Ueberall for support)
  • Added PAM (Portable Arbitrary Map) as serialization format (supports colors and transparency)

0.2.2 -- 2016-09-21
