Version 2.6 of package Corfu has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Corfu describes itself as: ============================= COmpletion in Region FUnction ============================= More at https://elpa.gnu.org/packages/corfu.html ## Summary: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CORFU.EL - COMPLETION IN REGION FUNCTION ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Corfu enhances in-buffer completion with a small completion popup. The current candidates are shown in a popup below or above the point, and can be selected by moving up and down. Corfu is the minimalistic in-buffer completion counterpart of the [Vertico] minibuffer UI. ## Recent NEWS: ━━━━━━━━━━━━━━━━━━━━━━ CORFU.EL - CHANGELOG ━━━━━━━━━━━━━━━━━━━━━━ 1 Development ═════════════ • corfu-popupinfo: Faster scrolling speed. • corfu-popupinfo: Fix Emacs 30 deprecation warning. 2 Version 2.6 (2025-12-07) ══════════════════════════ • Bugfixes. • Add name to Corfu child frame to improve readability of `(frame-list)'. • TTY: Fix child frame misalignment due to internal border. • TTY: Hide frame immediately. • TTY: Adjust default faces for low-color terminals. 3 Version 2.5 (2025-11-15) ══════════════════════════ • `corfu-auto-trigger': New customization variable to trigger immediate completion after certain characters. See also `cape-capf-trigger'. • `corfu-on-exact-match': Change default from `insert' to `nil', which is more compatible with auto completion and template/snippet/abbreviation expansion. • Improve compatibility with Eglot. Fix a manual completion bug in the case when Eglot provided no matching candidates. • Experimental: Use new function `set-frame-position-and-size' if available. See the patch on [emacs-devel] by Martin Rudalics. [emacs-devel] <https://lists.gnu.org/archive/html/emacs-devel/2025-11/msg00322.html> 4 Version 2.4 (2025-10-13) ══════════════════════════ • Require Emacs 29.1. • Handle mixed tty/graphical displays. • Do not enable Corfu in read-only buffers. 5 Version 2.3 (2025-06-12) ══════════════════════════ • Minor corrections and fixes. 6 Version 2.2 (2025-05-26) ══════════════════════════ • Guard Corfu hooks to automatically print stack traces in order to ease debugging. 7 Version 2.1 (2025-04-22) ══════════════════════════ • `corfu-history-duplicate' and `corfu-history-decay': New customization options to adjust the rank of duplicate history elements, such that they appear earlier in the completion list. • `corfu-history-mode': Add `corfu-history' to `savehist-minibuffer-history-variables' in order to save the history if `savehist-mode' is enabled. 8 Version 2.0 (2025-03-28) ══════════════════════════ • `corfu-quick': Ensure that popup does not move. 9 Version 1.7 (2025-01-28) ══════════════════════════ • Bugfixes only. 10 Version 1.6 (2024-12-22) ═══════════════════════════ • Require Emacs 28.1. • Use fringe to display scroll bar. This change improves performance and makes sure that the scroll bar cannot be pushed outside the child frame by the content. This affects for example `cape-emoji'. • Improve suffix alignment. • Remember popup width during completion to avoid width fluctuations. Basically the popup is only allowed to grow. • `corfu-insert-separator': Jump back to prompt if a candidate is previewed. 11 Version 1.5 (2024-07-26) ═══════════════════════════ • New customization variable `global-corfu-minibuffer' to enable Corfu in the minibuffer. • Unbind `C-a' in `corfu-map'. This binding is only needed in modes which override `C-a' instead of remapping `move-beginning-of-line'. • Unbind `<tab>' in `corfu-map'. This binding is only needed in modes which bind `<tab>' instead of `TAB', as was the case in old versions of Org. If you use such a mode, please report this as a bug for this mode. In the meantime you can use `(keymap-set corfu-map "<tab>" #'corfu-complete)'. • Add new command `corfu-send' as alternative to `corfu-insert'. • `corfu-popupinfo': Support both `face' and `font-lock-face' highlighting. • Bump Compat dependency to Compat 30. 12 Version 1.4 (2024-05-23) ═══════════════════════════ • `corfu-auto-commands': Add `delete-backward-char'. 13 Version 1.3 (2024-04-05) ═══════════════════════════ • Preserve currently selected candidate on further input. This matters if candidate preview is disabled (`corfu-preview-current=nil'). • Add new command `corfu-expand' bound to `M-TAB' by default. The command expands the input via `completion-try-completion', for example the `basic' completion style expands the common prefix of all candidates. 14 Version 1.2 (2024-01-23) ═══════════════════════════ • Support the EXWM window manager. • Optimization: Reduce auto completion timer overhead. • Use `internal-border-width' instead of `child-frame-border-width'. • Internal refactoring: Do not use buffer-local variables. • Internal refactoring: Store `completion-extra-properties' as part of `completion-in-region--data'. 15 Version 1.1 (2023-12-27) ═══════════════════════════ • Deduplicate candidates with respect to `equal-including-properties', such that … …
