In mpc.el I list the current songs with various of their info (duration, title, artist, ...) in columns, so I have the same problem there. I use truncate-string-to-width and do keep one extra column, but it's not always sufficient to avoid misalignment when the proportional font has some "very wide" chars. Also, I suffer from the reverse problem, that for columns where the text contains lots of narrow chars, truncate-string-to-width ends up being pessimistic, which is less harmful but wastes valuable screen estate and looks weird. My understanding of the redisplay engine makes me believe that a `:truncate-at' display property (and/or a combined :truncate-at-or-align-to) should be doable with good efficiency without too much extra gymnastics. And no, sorry, I'm not volunteering to implement it. Stefan ^ permalink raw reply [flat|nested] 4+ messages in thread

No promises, but I hope to give :wrap-column (#19661) a try, and I guess that :truncate-at wouldn’t be all that faraway from there. -- FSF associate member #7257 http://boycottsystemd.org/ … 3013 B6A0 230E 334A ^ permalink raw reply [flat|nested] 4+ messages in thread

I think :truncate-at will be way simpler to implement than :wrap-column. ^ permalink raw reply [flat|nested] 4+ messages in thread
