Release v0.7.0 · svioletg/lydian

Breaking changes:

[feature] A duration limit for media items can now be set using the max-duration config key, which
specifies the limit in seconds using a positive integer (setting to 0 will disable the limit)
- max-duration-allow-unknown specifies whether tracks with an unknown duration can be played
  or not when a duration limit is in place, defaulting to false
  - If no limit is set, this key is unused and tracks of unknown duration are always allowed
  - To save time on queueing, Lydian does not fetch a track's duration until it needs to, meaning
    items queued from a playlist URL won't have their duration checked against the limit until
    they are next in line
[feature] lydian can now be run with the -V or --version option to display the installed Lydian
version and exit without starting the bot
[feature] The "now playing" view now shows the approximate current timestamp of the playing media
(#13)
- Slight network delays will likely cause this number to be slightly inaccurate, but it should
  remain close enough for reference
[fix] Fixed filesize strings in the config with single digits raising an error due to a typo in the
regex used to match them

Added the -V/--version option to the lydian package command
- When used, Lydian's version is printed out and the script immediately exits
Added config key max-duration (integer)
Added config key max-duration-allow-unknown (boolean)
Added class config.Config.ConfigField
Added class config.Config.ConfigFieldMeta
Added method config.Config.set()
Added property config.Config.fields
Added function util.compose()
Added support for validator functions in config.Config fields, which can be given with the
'validators' key of a given field's metadata argument as a single function or iterable of
functions

Having debug mode enabled no longer forces the log level to "DEBUG" level
cogs.voice.MediaItem.duration_str now returns ?:?? for an unknown duration instead of None
cogs.voice.MediaItem.embed() now accepts an optional timestamp keyword argument to show the
current time alongside its duration
TOML configuration keys are now in snake_case instead of kebab-case; though the latter is more
common in TOML, it's ultimately unnecessary to keep converting keys between the two cases where
needed
const.LogLevel is now an IntEnum subclass instead of StrEnum
config.Config updating and loading from TOML is now handled in the class itself in a simpler
fashion than using util.DataclassUpdateMixin (#26)

Removed mixin class util.DataclassUpdateMixin
- Only used for updating the configuration object, which now handles updating in its own class

Fixed single-digit filesize numbers in TOML config not matching pattern
Queue no longer stops when encountering an error, will now skip problematic items until one can be
played or the queue is empty (#25)
