Changelog

0.5.1

sqlalchemy: add unbound_fk(), bound_fk()
Add sqlalchemy_async module with SQLAlchemy() async database binding.
- Supports being used as an async context manager
- Automatically handles commit and rollback
sqlalchemy_async also offers async_query()
Changed sqlalchemy.parent_children() to use lazy='selectin' by default
Add timed_cache(), alru_cache(), TimedDict(), none_pass(), twocolon_list(), quote_css_string(), must_be()
Add module calendar with want_* date type conversion utilities and age_and_days()
Move obsolete stuff to obsolete package (includes configparse 0.3 as of now)
Add redact module with redact_url_password()
Add more exceptions: NotFoundError(), BabelTowerError()
Add sass module
Add quart module with negotiate(), add_rest(), add_i18n(), WantsContentType
Add dei module: it implements a compact and standardized representation for pronouns, inspired by the one in use at PronounDB

Fixed return types for .sqlalchemy module.
sqlalchemy.parent_children() now takes a lazy parameter. Backported from 0.5.1.

pydantic is now a hard dependency
ConfigProperty has now been generalized: check out classtools.ValueProperty
BREAKING: Changed the behavior of makelist(): different behavior when used with callables.
- When applied as a decorator on callable, it converts its return type to a list.
- Pass wrap=False to treat callables as simple objects, restoring the 0.3 behavior.
New module lex to make tokenization more affordable — with functions symbol_table() and lex()
Add dorks module and flask.harden(). dorks contains common endpoints which may be target by hackers
Add sqlalchemy.bool_column(): make making flags painless
Introduce rb64encode() and rb64decode() to deal with issues about Base64 and padding
- b64encode() and b64decode() pad to the right
- rb64encode() and rb64decode() pad to the left, then strip leading 'A' in output
Added addattr(), PrefixIdentifier(), mod_floor(), mod_ceil()
First version to have unit tests! (Coverage is not yet complete)

Fixed return types for .sqlalchemy module.
sqlalchemy.parent_children() now takes a lazy parameter. Backported from 0.5.1.

Fixed a bug in b64decode() padding handling which made the function inconsistent and non injective. Now, leading 'A' is NEVER stripped.

Fixed ConfigValue behavior with multiple sources. It used to iterate through all the sources, possibly overwriting; now, iteration stops at first non-missing value

Fixed cb32 handling. Now leading zeros in SIQ's are stripped, and .from_cb32() was implemented

Fixed leftovers in snowflake module from unchecked code copying — i.e. SnowflakeGen.generate_one() used to require an unused typ= parameter
Fixed a bug in id_column() that made it fail to provide a working generator — again, this won't be backported

Fixed cb32encode() and b32lencode() doing wrong padding — UNSOLVED in 0.2.x which is out of support, effective immediately
Changed behavior of kwargs_prefix() which now removes keys from original mapping by default
Add SQLAlchemy auth loaders i.e. sqlalchemy.require_auth_base(), flask_sqlalchemy. What auth loaders do is loading user token and signature into app
sqlalchemy: add parent_children() and create_session()
Implement UserSigner()
Improve JSON handling in flask_restx
Add base2048 (i.e. BIP-39) codec
Add split_bits(), join_bits(), ltuple(), rtuple(), ssv_list(), additem()
Add markdown extensions
Add Snowflake manipulation utilities
