v1.0.0

First stable release of vui.el - a declarative, component-based UI library for Emacs.

Breaking Changes (since RC releases)

Symbol Prefix Rename: All public macros now use the vui- prefix to comply with MELPA naming conventions:

• defcomponent → vui-defcomponent
• defcontext → vui-defcontext
• use-effect → vui-use-effect
• use-ref → vui-use-ref
• use-callback → vui-use-callback
• use-callback* → vui-use-callback*
• use-memo → vui-use-memo
• use-memo* → vui-use-memo*
• use-async → vui-use-async

See the README section "Using Shorter Names (Shorthands)" for how to use aliases or read-symbol-shorthands if you prefer the shorter names.

v1.0.0-rc.3

Added

• vui-mode major mode for VUI buffers. Provides vui-mode-map that users and packages can extend (e.g., for ace-link). Packages using VUI can derive their own modes from vui-mode to add custom keybindings while preserving VUI and widget functionality.
• Documentation of Emacs 29 single-widget TAB navigation limitation (upstream bug#70594, fixed in Emacs 30).

Fixed

• vui-table now respects :indent from parent vui-vstack. Previously, only the first line of a table was indented; now all lines are properly indented.
• Cursor preservation now uses path-based widget tracking instead of index-based. Cursor correctly follows widgets when other widgets are added or removed before them. Previously, adding a widget above the cursor position would cause the cursor to land on the wrong widget after re-render.

Changed

• vui-mount and vui-render now enable vui-mode instead of using kill-all-local-variables. This preserves derived modes and their keybindings across re-renders.
