tll with compilation mode stalls?

[pendix]

When I run a compilation command (grep -n) which produces too long lines, the buffer goes to first TLL, shows it ok and stalls. On each C-g, the output continues until next TLL and stalls, until eof.

How is your tll set up? Did you add compilation-mode to too-long-lines-special-buffer-modes? What emacs version are you using?

tll will call too-long-lines-hide after every change, which I assume will make your emacs unresponsive if lots of very long lines displayed in your compilation-buffer.

When I tried to reproduce your issue I could provoke a similar behaviour by just outputing a huge file with lots of long lines, but it still worked reasonably well if there are only a few long lines to hide.

I set it up with following .emacs block:

(require 'too-long-lines-mode)
(setq too-long-lines-threshold 10000)
(setq too-long-lines-show-number-of-characters 200)
(add-to-list 'too-long-lines-special-buffer-modes 'compilation-mode)
(too-long-lines-mode)

Emacs version is 24.3.1.

Interesting that you are still on Emacs 24, maybe consider trying if your problem goes away when you update to Emacs 25?
