onMouseMove (and findHyperlinkAt, which it calls) read v.viewLines without holding writeMutex, unlike every other reader. They run on the event-handling goroutine, so a re-render on the task goroutine can shrink or rebuild viewLines between onMouseMove's bounds check and findHyperlinkAt's indexing, causing an out-of-range panic (observed: "index out of range [60] with length 0" while hovering during a diff re-render). Take writeMutex for the duration, like the other viewLines readers do, so the check and the access see the same slice. Pre-existing, but the off-screen re-render rebuilds viewLines on the task goroutine more often, widening the window.
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
