  • Fix possible panic with empty content
  • Fix cache
• Fix menubar focus after action
• Pin enumset version (fix compilation error)

This releases is quite large and includes some breaking changes:

• Cursive::new() has been renamed Cursive::default(). Cursive::new is now used to select a backend, allowing third-party backends.
• Scrolling is now handled by a new view wrapper, ScrollView. For TextView, SelectView and ListView, it is opt-in, by wrapping it in a ScrollView or calling .scrollable() from the Scrollable trait.
• Cursive::cb_sink() now returns a crossbeam_channel::Sender instead of chan::Sender. The API is mostly similar.
• SelectView::selection now returns a Option<Rc<T>> instead of panicking on an empty list.
• The features of AnyView have been merged into the regular View, so you should not need to use AnyView directly, and can only use View.
• Vec4 has been renamed to Margins.

In addition, many non-breaking changes are present as well:

• Callbacks sent through Cursive::cb_sink() are now processed instantly, without the need for set_fps.
• Backends are now a dynamic choice rather than a comile-time selection.
  • This means library do not need to bother with backend features anymore
  • Features are still there to add available backends, but they are mutually compatible.
• Events are batch-processed, resulting in higher performance when a lot of events are sent at once (for instance when scrolling with the mouse).
• Some methods now return a callback:
  • SelectView::{set_selection, select_up, select_down, remove_item}
  • EditView::{set_content, insert, remove}
• API additions:
  • StackView::find_layer_from_id
  • SelectView::insert_item
  • TextArea::{enable, disable}
  • rect::Rect
• Various bugfixes

• Adds Printer::with_theme to apply a different theme to a subtree.

• Add Cursive::clear_global_callbacks
• Bugfixes:
  • Fix non-ASCII input with pancurses backend
  • Fix StackView::move_layer
  • Fix layout computation for SelectView
  • Remove unused maplit dependency for termion and blt backends

Major update. Check CHANGELOG.md for complete list.

Highlights:

• Add styled text support.
  • TextView can now display a StyledString. A StyledString can be built from multiple sources, including parsing markdown text.
• Fixed line-breaking algorithm (now doesn't break at invalid locations).
• Refactored ColorStyle.
• Added TextContent to manage the content from a TextView remotely.
• StackView: added methods to re-order the layers, and reposition them on screen.
• Cursive::cb_sink can now accept FnOnce callbacks
• Various methods were added to query/update the selection/focus for most views.
• Usual bunch of bugfixes.

• Add mouse support to pancurses
• Better key modifier detection on ncurses backend
• Fix possible panic in TextArea::set_content
• Add TextArea::cursor(&self) -> usize and TextArea::set_cursor(&mut self, usize)
• Use Vec::splice instead of VecExt from the odds crate. This may require rustc > 1.21

• Fix drawing bug in LinearLayout
• Update pancurses backend to 0.12

• Correctly ignore unused keys in SelectView
• Fix a possible crash with LinearLayout

• Fix mouse-related bugs in ListView and SelectView.

• Bugfixes regarding bad mouse handling
