Subject: Placing eol glyph (buffer-display-table) before an overlay after-string.
Date: Fri, 11 Aug 2017 23:14:31 -0700 [thread overview]
Message-ID: <m2shgxfh2w.wl%esq@lawlist.com> (raw)
My goal is to use a pilcrow to represent line endings, and this option can be set up using the appropriate buffer-display-table entry.
I have a custom minor mode that draws cross-hairs the length of the screen to track the cursor position, which requires the use of the overlay after-string property. Emacs draws the eol glyph after the overlay after-strings are placed -- i.e., to the right of the after-string. The result is that the eol glyph (e.g., pilcrow) is always on the far right of the after-string overlay. I want the eol glyph to appear at the end of the line of text, and the overlay after-string should come after the eol glyph (not before).
Is it feasible to reverse the order such that the eol glyph is laid before the overlays containing the after-string property?
A hint as to the locations (in the C code) where I would start working on reversing the order would be greatly appreciated.
If there is a better way to handle this than trying to reverse the order in which things are happening, any insight would be helpful.
WORKAROUND: I have been using a custom XPM image of a pilcrow that is the beginning of the after-string, and I change its coloration (foreground/background) as needed. The problem with this approach is that the XPM does not look as good as a native eol glpyh, and the XPM would need to be adjusted depending upon the font and size of the font.
Thanks,
