This package adds fuzzy matching to company, powered by the sophisticated sorting heuristics in flx.
To install, either clone this package directly, or execute M-x package-install RET company-flx RET.
After the package is installed, you can enable company-flx by adding the following to your init file:
(with-eval-after-load 'company
(company-flx-mode +1))Use the variable company-flx-limit to control the number of candidates that are scored by flx. flx can be slow, and the default is set rather high, so if you experience lag, consider lowering the limit.
Crazy stuff simmers in my emacs-config, and every once and a while, it's worth sharing. This was no exception. It's been patiently evolving in my config for the better part of a year, and I think it's useful enough to benefit other people.
Also of interest is company-mode/company-mode #47.
This only works with the company-capf backend. Most sources use this backend, with the exception of the more advanced sources. Most backends should be re-written in terms of completion-at-point-functions eventually, although it's going to take a while.
The most important source that doesn't work is company-dabbrev.
