Changes¶

v0.5.2 (2020-09-04)¶

Bugfix: Add zero in front of GTIN-12 before extracting GS1 Prefix. GTIN-12s start with U.P.C. Company Prefixes, which have to be padded with a zero in front to convert them to valid GS1 Company Prefixes.
Change the error message in the top level parser’s ParseError to include the name of data type we failed to parse.

Bugfix: biip.gtin.Rcn.without_variable_measure() returns the instance unchanged for RCNs intended for usage within a company. Previously, this crashed as region was unset for company RCNs.

Breaking change: Change argument separator_char to separator_chars in plural, accepting an iterable of multiple characters.

Breaking change: Change return value of parse() from Union[Gtin, GS1Message] to ParseResult.
If a Symbology Identifier is present, select parser based on it.
Improved parsing error messages.

Add Sscc class to parse, validate, and format Serial Shipping Container Codes (SSCC).

Add filter() to find all parsed Element Strings that match the criteria.
Add get() to find first parsed Element String that matches the criteria.
Add decimal field which is set for AIs with weight, volume, dimensions, dicount percentages, and amounts payable.
Add money field which is set for AIs with both amounts payable and currency. This field is only set if the optional dependency py-moneyed is installed.
Strip surrounding whitespace before parsing.

Detect Restricted Circulation Numbers (RCN) and return a subclass of Gtin, Rcn, with additional fields and helpers for working with RCNs.
Classify an RCN as being restricted to either a geographical region or to a company.
Support interpreting RCNs according to varying rules depending on the geographical region specified by the user.
Support for zeroing out the variable measure part, to help with looking up trade items in a database or similar.
Add RCN rules for the Baltics, Great Britain, Norway, and Sweden.
Strip surrounding whitespace before parsing.
Bugfix: Keep all leading zeros in GTIN-8.
Bugfix: Convert GTIN-8 to GTIN-12 before extracting GS1 Prefix.

Raise ParseError if there is less than 8 or more than 14 significant digits in the barcode.

GS1Message can parse GS1-128 data.
GS1ApplicationIdentifier recognizes all 480 existing GS1 AIs.
GS1Prefix recognizes all existing GS1 prefixes.
checksums has functions to calculate check digits for numeric data and price/weight fields.

Support for validating, parsing, and converting between GTIN-8, GTIN-12, GTIN-13, and GTIN-14.

Initial release to reserve the name on PyPI.
