[Message part 1 (text/plain, inline)]
Dear Everyone,
I have recently discovered TeX-fold-mode and tried to set it. Before I used
prettify-symbols-mode.
There seem to be a problem with propagating text properties when folding.
There seem to be two wrong behaviors (related or unrelated?).
1. When folding a macro that includes its text arguments when the
arguments are fontified the fontification gets propagated incorrectly. I
think it gets applied twice, that is wrong when the fontification is not
idempotent e.g. relative size specification
2. In math mode (maybe not only) all macros (math and non-math) when
folded completely disregard fontification. This looks really bad if you have
a subscript of, say, a sum or an integral and there you have a macro. The
folded version is of the wrong size.
I illustrate with examples
Consider the following LaTeX file (attached as main.tex):
\documentclass{amsart}
\begin{document}
\title{Simple AMSart}
\author{Author McAuthorface}
\maketitle
\section{Section \textit{a} : a \LaTeX macro}
\begin{equation*}
\int_{\alpha + \beta = \LaTeX + \dots }
\end{equation*}
\end{document}
With the following configuration of auctex (a complete init.el is attached)
(setq TeX-parse-self t)
(require 'tex)
(add-hook 'LaTeX-mode-hook (lambda ()
(TeX-fold-mode 1)))
1. The default fontification makes "Section :" slightly larger than
normal. This is correct.
* The macro \LaTeX gets folded to look like the surrounding text in
the title: CORRECT
* The macro \textit{a} folds into an "a" as specified by
TeX-fold-macro-spec-list (value included below) but it gets rendered much
larger than the surrounding text
* I believe because the "enlargement" gets applied twice, but I am not
sure.
2. Auctex makes the subscript of the integral in the equation small and
lowered.
* After folding the Greek symbols and the other macros they appear to
be the same size as "normal" text so they do not inherit the surrounding
fontification.
Thanks!
Gennady
