From a4e0b9785e409e9e660171cea76dfcc5fdafad9b Mon Sep 17 00:00:00 2001 From: Bram Moolenaar Date: Sat, 1 Oct 2022 19:43:52 +0100 Subject: patch 9.0.0634: evaluating "expr" options has more overhead than needed Problem: Evaluating "expr" options has more overhead than needed. Solution: Use call_simple_func() for 'foldtext', 'includeexpr', 'printexpr', "expr" of 'spellsuggest', 'diffexpr', 'patchexpr', 'balloonexpr', 'formatexpr', 'indentexpr' and 'charconvert'. --- runtime/doc/diff.txt | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'runtime/doc/diff.txt') diff --git a/runtime/doc/diff.txt b/runtime/doc/diff.txt index a66df1e273..e5321c586d 100644 --- a/runtime/doc/diff.txt +++ b/runtime/doc/diff.txt @@ -376,6 +376,9 @@ Additionally, 'diffexpr' should take care of "icase" and "iwhite" in the 'diffopt' option.
