Version 2.1 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 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. 2 Version 2.0 (2025-03-28) ══════════════════════════ • `corfu-quick': Ensure that popup does not move. 3 Version 1.7 (2025-01-28) ══════════════════════════ • Bugfixes only. 4 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. 5 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. 6 Version 1.4 (2024-05-23) ══════════════════════════ • `corfu-auto-commands': Add `delete-backward-char'. 7 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. 8 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'. 9 Version 1.1 (2023-12-27) ══════════════════════════ • Deduplicate candidates with respect to `equal-including-properties', such that backends can provide equal candidate strings, which only differ in their text properties and annotations. • Ensure that the string passed to the `:exit-function' retains the candidate properties, when possible. The properties are guaranteed to exist when a candidate is selected explicitly, but may be missing when candidates are completed in a stepwise manner. • `corfu-on-exact-match': Add value `show' to the customization option. With this setting the Corfu popup will be shown even if there is only a single matching candidate. 10 Version 1.0 (2023-12-01) ═══════════════════════════ • Bug fixes. • `corfu-quick': Use a slightly different scheme to support more candidates. • `corfu-reset': Quit immediately if input did not change. • Support `completion-lazy-hilit'. 11 Version 0.38 (2023-08-14) ════════════════════════════ • `corfu-quick': Bugfix. • `corfu-mode-map': Add mode map. • Replace `corfu-excluded-modes' with `global-corfu-modes', the Emacs 28 convention for globalized minor modes. 12 Version 0.37 (2023-07-02) ════════════════════════════ • Bugfixes. • Improve child frame display code, `corfu--popup-show' takes a `posn' argument. • Ensure that the popup font matches the font of the parent frame. • Close popup when window selection changes. • Remove `corfu-history-length'. Instead set the `history-length' property of `corfu-history' variable. … …
