|
|
|
|
All notable changes to this project are documented here.
|
|
|
|
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
|
|
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

|
|
|
## [Unreleased]
|
|
|
|
### Added
|
|
|
|
- The Button widget.
|
|
- A function that draws text vertically.
|
|
- The LineChart widget can display X axis labels in vertical orientation.
|
|
- The LineChart widget allows the user to specify a custom scale for the Y
|
|
axis.
|
|
- The LineChart widget now has an option that disables scaling of the X axis.
|
|
Useful for applications that want to continuously feed data and make them
|
|
"roll" through the linechart.
|
|
- The LineChart widget now has a method that returns the observed capacity of
|
|
the LineChart the last time Draw was called.
|
|
- The LineChart widget now supports zoom of the content triggered by mouse
|
|
events.
|
|
- The Text widget now has a Write option that atomically replaces the entire
|
|
text content.
|
|
- A non-blocking event distribution system that can throttle repetitive events.
|
|
|
|
### Changed
|
|
|
|
- Termbox is now initialized in 256 color mode by default.
|
|
- Generalized mouse button FSM for use in widgets that need to track mouse
|
|
button clicks.
|
|
- The infrastructure now uses the non-blocking event distribution system to
|
|
distribute events to subscribers. Each widget is now an individual
|
|
subscriber.
|
|
- The infrastructure now throttles event driven screen redraw rather than
|
|
redrawing for each input event.
|
|
- Widgets can now specify the scope at which they want to receive keyboard and
|
|
mouse events.
|
|
|
|
#### Breaking API changes
|
|
|
|
##### High impact
|
|
|
|
- The constructors of all the widgets now also return an error so that they
|
|
can validate the options. This is a breaking change for the following
|
|
widgets: BarChart, Gauge, LineChart, SparkLine, Text. The callers will have
|
|
to handle the returned error.
|
|
|
|
##### Low impact
|
|
|
|
- The container package no longer exports separate methods to receive Keyboard
|
|
and Mouse events which were replaced by a Subscribe method for the event
|
|
distribution system. This shouldn't affect users as the removed methods
|
|
aren't needed by container users.
|
|
- The widgetapi.Options struct now uses an enum instead of a boolean when
|
|
widget specifies if it wants keyboard or mouse events. This only impacts
|
|
development of new widgets.
|
|
|
|
### Fixed
|
|
|
|
- The LineChart widget now correctly determines the Y axis scale when multiple
|
|
series are provided.
|
|
- Lint issues in the codebase, and updated Travis configuration so that golint
|
|
is executed on every run.
|
|
- Termdash now correctly starts in locales like zh_CN.UTF-8 where some of the
|
|
characters it uses internally can have ambiguous width.
|
|
|

### Fixed

|
|
zero anchored to adaptive.
|
|
- Lint errors reported on the Go report card.
|
|
- Widgets now correctly handle a race when new user data are supplied between
|
|
