I've been using pandoc and emacs to convert beamer presentations to markdown format. In the beamer presentations we highlighted certain code in example code blocks red. Pandoc has left me to get rid of these by hand. I have been trying to use M-x replace-regexp to find all $alert...$ and replace it with ....

I keep getting an error saying:

Invalid use of '' in replacement text

Here is an example of what I'm trying to replace

$alertbool has_burnup;$
$alertconst Variable Value & _burnup;$

$alertTHERMAL_H$

Should be replaced as:

bool has_burnup;
const Variable Value & _burnup;

THERMAL_H

Here is what I'm currently trying

M-x replace-regex <RET> $\alert.+$ <RET> [^]+(?=})

These regexp work when using an online testing environment. Why won't it work in emacs?

latex regular-expressions replace isearch

Text to keep needs parenthesis. That
works here:

M-x query-replace-regexp RET $\alert(.+).* RET 1 RET

From a program use
re-search-forward and replace-match
