From: Keith David Bershatsky <esq <at> lawlist.com> To: 17684 <at> debbugs.gnu.org Subject: bug#17684: 24.4.50; Feature Request -- Vertical Lines to the Left of and Through Characters Date: Tue, 03 Jun 2014 13:36:51 -0700
As a feature request, please consider adding the ability to include vertical lines to the left of and also through characters. CAVEAT: The vertical line plus the character should be equal to only (1) `point` -- like a vertical cursor bar and a character to the right. This new feature has many applications, including, but not limited to: * A thin fill column indicator line that can span the vertical length of the window / buffer. * Thin tab setting indicators in the form of vertical lines for each tab set. (This is built-in to Sublime Text.) * A visual vertical division between different parts of the same buffer. * A thin vertical line (from top to bottom of the window) that tracks the cursor position. See the following stackoverflow thread for a screenshot of how this looks, including the workaround / answer to the question: http://stackoverflow.com/questions/23744237/emacs-how-to-create-a-vertical-strike-through-effect My workaround shrinks the character to the right so that the visual sentence length is not altered. The vertical bar cursor that is built-in to Emacs can sit next to a character without shrinking said character -- so implementation of a vertical line to the left of the character would be similar to how the cursor presently works. BONUS: As a related feature request, please consider adding the ability to draw these vertical lines (from top to bottom of the window) virtually instantaneously. Creating these vertical lines in `elisp` when `visual-line-mode` is active is extremely time consuming to perform all the calculations (up to 0.25 seconds from start to finish) and needs to be done with an `idle-timer` so as not to slow down the normal movement of the cursor or typing text quickly. The calculation and placement of overlays can be sped up significantly by *not* calculating for `visual-line-mode`, but I am *very* fond of that mode.
