From e62e76c38322ebb88bcf54a933a07291d9e7c5ba Mon Sep 17 00:00:00 2001 From: Guido van Rossum Date: Thu, 22 Apr 1999 13:38:40 +0000 Subject: Super-elegant patch by Tim Peters that speeds up colorization dramatically (up to 15 times he claims). Works by reading more than one line at a time, up to 100-line chunks (starting with one line and then doubling up to the limit). On a typical machine (e.g. Tim's P5-166) this doesn't reduce interactive responsiveness in a noticeable way. --- Tools/idle/ColorDelegator.py | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/Tools/idle/ColorDelegator.py b/Tools/idle/ColorDelegator.py index 5b4da7c..147f749 100644 --- a/Tools/idle/ColorDelegator.py +++ b/Tools/idle/ColorDelegator.py @@ -180,9 +180,12 @@ class ColorDelegator(Delegator): chars = "" mark = head + lines_to_get = 1 is_ok = was_ok = 0 while not (was_ok and is_ok): - next = self.index(mark + " lineend +1c") + next = self.index(mark + "+%d lines linestart" % + lines_to_get) + lines_to_get = min(lines_to_get * 2, 100) was_ok = "SYNC" in self.tag_names(next + "-1c") line = self.get(mark, next) ##print head, "get", mark, next, "->", `line` -- cgit v0.12
