Changelog

To be released

## v0.5.1 - 2019-04-14

Fixed

• Fix a panic in the Sparkline widget

v0.5.0 - 2019-03-10

Added

• Add a new curses backend (with Windows support thanks to pancurses).
• Add Backend::get_cursor and Backend::set_cursor methods to query and set the position of the cursor.
• Add more constructors to the Crossterm backend.
• Add a demo for all backends using a shared UI and application state.
• Add Ratio as a new variant of layout Constraint. It can be used to define exact ratios constraints.

Changed

• Add support for multiple modifiers on the same Style by changing Modifier from an enum to a bitflags struct.

So instead of writing:

let style = Style::default().modifier(Modifier::Italic);

one should use:

let style = Style::default().modifier(Modifier::ITALIC);
// or
let style = Style::default().modifier(Modifier::ITALIC | Modifier::BOLD);

Fixed

• Ensure correct behavoir of the alternate screens with the Crossterm backend.
• Fix out of bounds panic when two Buffer are merged.

v0.4.0 - 2019-02-03

Added

• Add a new canvas shape: Rectangle.
• Official support of Crossterm backend.
• Make it possible to choose the divider between Tabs.
• Add word wrapping on Paragraph.
• The gauge widget accepts a ratio (f64 between 0 and 1) in addition of a percentage.

Changed

• Upgrade to Rust 2018 edition.

Fixed

• Fix rendering of double-width characters.
• Fix race condition on the size of the terminal and expose a size that is safe to use when drawing through Frame::size.
• Prevent unsigned int overflow on large screens.

v0.3.0 - 2018-11-04

Added

• Add experimental test backend

v0.3.0-beta.3 - 2018-09-24

Changed

• show_cursor is called when Terminal is dropped if the cursor is hidden.

v0.3.0-beta.2 - 2018-09-23

Changed

• Remove custom termion backends. This is motivated by the fact that termion structs are meant to be combined/wrapped to provide additional functionalities to the terminal (e.g AlternateScreen, Mouse support, ...). Thus providing exclusive types do not make a lot of sense and give a false hint that additional features cannot be used together. The recommended approach is now to create your own version of stdout:

let stdout = io::stdout().into_raw_mode()?;
let stdout = MouseTerminal::from(stdout);
let stdout = AlternateScreen::from(stdout);

and then to create the corresponding termion backend:

let backend = TermionBackend::new(stdout);

The resulting code is more verbose but it works with all combinations of additional termion features.

v0.3.0-beta.1 - 2018-09-08

Changed

• Replace Item by a generic and flexible Text that can be used in both Paragraph and List widgets.
• Remove unecessary borrows on Style.

v0.3.0-beta.0 - 2018-09-04

Added

• Add a basic Crossterm backend

Changed

• Remove Group and introduce Layout in its place
  • Terminal is no longer required to compute a layout
  • Size has been renamed Constraint
• Widgets are rendered on a Frame instead of a Terminal in order to avoid mixing draw and render calls
• draw on Terminal expects a closure where the UI is built by rendering widgets on the given Frame
• Update Widget trait
  • draw takes area by value
  • render takes a Frame instead of a Terminal
• All widgets use the consumable builder pattern
• SelectableList can have no selected item and the highlight symbol is hidden in this case
• Remove markup langage inside Paragraph. Paragraph now expects an iterator of Text items

v0.2.3 - 2018-06-09

Added

• Add start_corner option for List
• Add more text aligment options for Paragraph

v0.2.2 - 2018-05-06

Added

• Terminal implements Debug

Changed

• Use FnOnce instead of FnMut in Group::render

v0.2.1 - 2018-04-01

Added

• Add AlternateScreenBackend in termion backend
• Add TermionBackend::with_stdout in order to let an user of the library provides its own termion struct
• Add tests and documentation for Buffer::pos_of
• Remove leading whitespaces when wrapping text

Fixed

• Fix debug_assert in Buffer::pos_of
• Pass the style of SelectableList to the underlying List
• Fix missing character when wrapping text
• Fix panic when specifying layout constraints

v0.2.0 - 2017-12-26

Added

• Add MouseBackend in termion backend to handle scroll and mouse events
• Add generic Item for items in a List

Changed

• Rename TermionBackend to RawBackend (to distinguish it from the MouseBackend)

• Generic parameters for List to allow passing iterators as items

• Generic parameters for Table to allow using iterators as rows and header

• Generic parameters for Tabs

• Rename border bitflags to Borders

• Run latest rustfmt on all sources

Removed

• Drop log4rs as a dev-dependencies in favor of stderrlog
