Moves complex layout determination logic (grid grouping, stack levels, positioning) from `EventRenderer` to a new `EventLayoutCoordinator` class.
Delegates layout responsibilities to the coordinator, significantly simplifying the `EventRenderer`'s `renderColumnEvents` method. Refines `EventStackManager` by removing deprecated layout methods, consolidating its role to event grouping and core stack level management.
Improves modularity and separation of concerns within the rendering pipeline.
Introduces a 3-phase algorithm in `EventStackManager` for dynamic event positioning. Groups events by start time proximity to determine optimal layout.
Optimizes horizontal space by using side-by-side grid columns for simultaneous events and allowing non-overlapping events to share stack levels. Supports nested stacking for late-arriving events within grid columns.
Includes comprehensive documentation (`STACKING_CONCEPT.md`) and a visual demonstration (`stacking-visualization.html`) to explain the new layout logic. Updates event rendering to utilize the new manager and adds extensive test coverage.
Enhances date validation and timezone handling using DateService, ensuring data integrity and consistency.
Refactors event rendering and dragging to correctly handle date transformations.
Adds a test plan for event stacking and z-index management.
Fixes edge cases in navigation and date calculations for week/year boundaries and DST transitions.
Replaces DateCalculator with DateService for improved date and time operations, including timezone handling.
This change enhances the calendar's accuracy and flexibility in managing dates, especially concerning timezone configurations.
It also corrects a typo in the `allDay` dataset attribute.
Improves date validation and adds flexible date/time formatting capabilities.
The date validation is updated to return a boolean and is incorporated directly into calling functions to throw errors, improving code readability and maintainability. DateService is extended with functions for formatting time in 12-hour format, getting day names, and formatting date ranges with customizable options.
Adds DateService using date-fns-tz for robust time zone
conversions and date manipulations.
Refactors DateCalculator and TimeFormatter to utilize the
DateService, centralizing date logic and ensuring consistent
time zone handling throughout the application.
Improves event dragging by updating time displays and data
attributes, handling cross-midnight events correctly.
Adds options for technical date and time formatting and includes the option to show seconds.
Updates time formatting to use UTC-to-local conversion and ensures consistent colon separators for time values.
Adjusts all-day event handling to preserve original start/end times.
Ensures consistent all-day event row height calculation across CSS and TypeScript.
The all-day event row height calculation is adjusted by removing redundant container padding from the TypeScript constant and synchronizing the CSS variable with the event height.
Additionally, the layout engine is directly tested in the test file for better coverage.
Updates the all-day event layout engine for better event
rendering, especially when dealing with partial week views.
The layout engine now correctly clips events that start
before or end after the visible date range, ensuring that
only relevant portions of events are displayed.
It also fixes event ordering.
Includes new unit tests to validate date range filtering and
clipping logic.
Adds comprehensive tests for the AllDayManager, covering various overlap scenarios.
Tests ensure correct row and column assignments for all-day events based on date ranges and overlaps.
Replaces individual event layout calculation with batch calculation for improved performance and test coverage.
Refactors all-day event rendering to use a layout engine
for overlap detection and positioning, ensuring events
are placed in available rows and columns.
Removes deprecated method and adds unit tests.
