Subject: Is it safe to use the combine-after-change-calls like this?
Date: Wed, 17 Apr 2019 00:21:10 +0000 [thread overview]
Message-ID: <PS1PR06MB2759C6E76C921A9FB6DD9254A8250@PS1PR06MB2759.apcprd06.prod.outlook.com> (raw)
I want to use it with multiple-cursors.el(https://github.com/magnars/multiple-cursors.el) like this:
1. When multiple-cursors activates, set combine-after-change-calls to t
2. Edit the buffer with multiple active cursors
3. Before multiple-cursors deactivates, call combine-after-change-execute and set combine-after-change-calls back to nil.
I’m using the package iedit.el(https://github.com/victorhge/iedit). It works like multiple-cursors.el, which has multiple active cursors.
The problem is that: when editing with multiple active cursors, emacs lags too much. It seems that most of cpu is used by functions in after-change-functions.
The issue: https://github.com/victorhge/iedit/issues/83
