Emacs: Name Completion
Emacs has many different word completion systems building. Here's a list of the most useful ones.
completion-at-point
- Alt+x
completion-at-point【Ctrl+Alt+i】 - For completing the word under cursor. Mostly used for completing function names in programing language source code. This works best in
emacs-lisp-modefor coding emacs lisp. Usually does not work for other languages, such as JavaScript, Python, Ruby, unless you install supporting packages.
completion-at-point, with plain gnu emacs in emacs-lisp-mode.
hippie-expand
For expanding current word to any matching string that occurs in any existing buffers. [see Emacs: Hippie Expand]
Abbrev Mode
For expanding current word to any string, emoji, template, etc. You define the abbrevs. [see Emacs: Abbrev Mode by Lisp Code]
Completion for Minibuffer Prompts
For minibuffer prompt name completion. (command name, variable name, file name.) [see Emacs: icomplete mode, fido mode]
