Subject: 11.89.1; Preview appears at the wrong position in the document
Date: Mon, 01 Feb 2016 19:32:56 +0100

With a document like the following, that contains a custom enumeration,
the preview generated by preview-latex for the math that is within the
[...] of the items, appears at the wrong position: After hitting C-c C-p
C-b, the document looks as follows

  \pcase[$\langtext{inc}$] h<begin embedded image>inc<end embedded
  image>ello

whereas of course I would expect

  \pcase[<begin embedded image>inc<end embedded image>] hello

Kind regards,
Ralf

Great, thanks! I will test this once a version with the fix is on (M)ELPA :D

Kind regards,

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

This is what I get with a recent AUCTeX and Emacs:

[preview.png (image/png, inline)]

[Message part 3 (text/plain, inline)]

My additions were these 2 lines:

\usepackage[textmath,displaymath,footnotes,sections,floats]{preview}
\PreviewMacro*[?[{@{[]}}{}]{\pcase}

where \PreviewMacro* tell preview how to deal your \pcase macro.  I
think the result is what you have expected, therefore I'm closing this
report.

Best, Arash
