Changelog

All notable changes to this project are documented here.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Added

  • 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.

Breaking API changes

  • 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.

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.
