Hi,
Simply put, can I tell Flymake to produce sound when a new error is 
"created" or an existing one fixed? Visually, flymake uses a different 
background color to indicate line statuses and posts the error and warnings 
counts, I think, to the mode line. However, neither is particularly easy to 
read out smartly with a Windows screen reader from Emacs, who just sees a 
large "console", so I'd like to get audio feedback in stead. I'm using 
flymake_lua from:

http://www.emacswiki.org/cgi-bin/wiki/FlymakeLua

Playing the sound as such

http://www.gnu.org/software/emacs/elisp/html_node/Sound-Output.html

or posting a message containing a bell to the message line monitored by the 
screen reader

http://www.gnu.org/software/emacs/emacs-lisp-intro/html_node/message.html

seems easy enough.

I've taken a quick look at the list of functions in flymake but didn't find 
hooks to add there. Nor did I find anything I could directly extend, in the 
Lua specific bits. I'm rather new to Elisp but have read the gist of 
Programming in Emacs Lisp.

On a side note, flymake is one of the many things that made me go wow when I 
saw it in Emacs. Others, that I'm also using in Lua, include 
outline-minor-mode matching functions, incremental regexp searches, the Lua 
mode itself (due to the indents I do with C-i), not to mention dynamic 
abbreviation  bound to the tab key, for locals and function names. Great 
features that go well together in coding.

Any help appreciated.
