The focused main view could be scrolled but not pointed at: there was no way to say "this line" or "these lines", which is what every line-level interaction needs — editing a line, copying part of a diff, and, later, staging. So a diff main view now always carries a selection while focused, starting at the first change already on screen so that focusing doesn't move the view. The mode of the selection lives on the main context (a single line, a range from a fixed anchor, or the change block around the cursor); the selected line and the range anchor stay in the view itself, whose native range select draws them, so there is no new highlight machinery. The modes and their keys are the ones the staging view has, including that the arrow keys step from block to block in hunk mode. A pane holds something to select only when what it is showing is a diff with changes in it, which the render works out once its content is final: a placeholder message is not a diff, and neither is a diff with nothing in it at all, such as a binary file's or an empty commit's. Whether a selection is then drawn there follows from the context stack, as it does for every other view. A click in the focused main view now has a meaning again: it selects the line it points at.

GOCUI - Go Console User Interface
Minimalist Go package aimed at creating Console User Interfaces. A community fork based on the amazing work of jroimartin
Features
- Minimalist API.
- Views (the "windows" in the GUI) implement the interface io.ReadWriter.
- Support for overlapping views.
- The GUI can be modified at runtime (concurrent-safe).
- Global and view-level keybindings.
- Mouse support.
- Colored text.
- Customizable editing mode.
- Easy to build reusable widgets, complex layouts...
About fork
This fork has many improvements over the original work from jroimartin.
- Written ontop of TCell
- Better wide character support
- Support for 1 Line height views
- Better support for running in docker container
- Customize frame colors
- Improved code comments and quality
- Many small improvements
- Change Visibility of views
