Fuzzy matching

Helm's built-in fuzzy matcher is activated for some commands. Helm's fuzzy matching is disabled by default. Currently these commands support fuzzy matching:

  • helm-recentf: set helm-recentf-fuzzy-match to t.
  • helm-mini: set helm-buffers-fuzzy-matching and helm-recentf-fuzzy-match to t.
  • helm-buffers-list: set helm-buffers-fuzzy-matching to t.
  • helm-find-files: fuzzy matching enabled by default.
  • helm-locate: set helm-locate-fuzzy-match to t.
  • helm-M-x: set helm-M-x-fuzzy-match to t.
  • helm-semantic: set helm-semantic-fuzzy-match to t.
  • helm-imenu: set helm-imenu-fuzzy-match to t.
  • helm-apropos: set helm-apropos-fuzzy-match to t.
  • helm-lisp-completion-at-point: set helm-lisp-fuzzy-completion to t.
  • helm-source-session: set helm-session-fuzzy-match to t.
  • helm-etags-select: set helm-etags-fuzzy-match to t.

To globally enable fuzzy matching for helm-mode:

  • set helm-mode-fuzzy-match to t.
  • set helm-completion-in-region-fuzzy-match to t.

IMPORTANT: For faster fuzzy matching, set helm-candidate-number-limit to 100 or less. Default is 100.
