Hello,
/I’ll first explain the situation and append the code to the message./
Go to code: [ M-x re-search-forward RET ^CODE RET ]
I read in Org mode a lot, and I dislike reading prose in monospace
fonts. So I have turned on ‘variable-pitch-mode’ for Org mode. But
because some stuff has to stay in stoichedon, so I set some faces to be
monospace:
I have also add a keyword to font-lock keywords as part of the Org hook,
so that I can have a face attached to initial whitespace and lists (-,
and 1., 2. etc). I set this face to monospace too, so that I have nice
aligned left line, while the actual prose stays in variable pitch.
I just updated today, from the default Org mode of Emacs 24.5 to the
latest release (8.3.2, from git).
The problems are as follows:
1. My code is buggy, and I can’t understand why. With previous Org some
font-lock actions were happening only after I hit enter at the end of a
line, and if I have less than 3 newlines at the end of the file
sometimes font-locking of headings didn’t work. For example, if I’m
writing a paragraph, I write it in a single physical line, and I use
word wrapping. If that paragraph happended to contain an inline
footnote, which I use very often, that note is not highlighted until I
insert a line-feed.
And with the new version, while the problem persists, when I hit enter,
thus inserting a newline at the end of a line, Emacs hangs up, and
sometimes I see this error:
org-element--current-element: Wrong type argument: integer-or-marker-p, nil
;; See end of message for the backtrace…
;; [ M-x re-search-forward RET ^BACK RET ]
But if I go to the next line and ‘open-line’, everything is O.K. Maybe
my keyword regex has a mistake?
2. In the new version of org mode, ‘org-block-background’ face is gone,
and I can’t set the face for block to use a monospace font. There is
the org-block face, which doesn’t affect the contents of org blocks,
e.g. src block. Basically, the text between the org-block delimiters
don’t get a face, so I can’t set the font for them. Any workarounds?
3. I do not know how to hook in properly to the org font-lock mechanism.
I read the code a bit, and apparently org builds the font-lock keywords
list local to the buffer when it is booting up as its major mode. I
know barely anything about font-lock, but from this fact I deduce that I
have to push in my keywords in a hook after it’s initialisation, but I
do not know if I do it properly.
I’ve written a wall of text, I’m sorry. I hope there’ll be someone to
help me out though, because the solution is beyond my comprehension of
Org and Emacs Lisp. Thanks in advance.
