delsel.el: Use an overlay to track the replacement text 2026-02-14T17:43:33+00:00 Kim F.

Rewrite flex completion with Gotoh algorithm 2026-02-13T23:46:11+00:00 João Távora 2026-02-03T12:14:03+00:00 aa181cd35220242a23fe98932386facaba18c4c5 The greedy regexp matching, broken scoring and broken highlight were sources of frequent complaints about the 'flex' matching style.

The greedy regexp matching, broken scoring and broken highlight were
sources of frequent complaints about the 'flex' matching style.  This
commit fixes that.

Inspired by the 'hotfuzz' style (available at
https://github.com/axelf4/hotfuzz) it uses a modified version of Gotoh's
1982 dynamic programming algorithm. It is strictly more correct than the
"old" flex.  For example, when matching the pattern 'goto' to no longer
will 'eglot-format' be sorted before some hypothetical much better
'goobarbaz-goto'.  And of course the highlighting is also correctly
placed on the 'goto', not scattered across the candidate.

Regarding performance, it is faster than the naive 'flex', primarily
because of the Elisp rewrite in minibuffer.el.  The matching and costing
algorithm matters but is not the bottleneck.

The Elisp parts of the style were almost completely decoupled from the
pcm/substring styles in lisp/minibuffer.el.  Only
'completion-flex-try-completion' uses some of pcm's code for pattern
augmentation.
