How to handle strings with commas in macros?

How to handle strings with commas in macros?

[William Denton]

I'm using macros to format names in a LaTeX export, like so:

#+latex_header: \newcommand\m[1]{\textsc{#1}}
#+macro: m \m{$1}

Thus

{{{m(William Denton)}}}

becomes

\m{William Denton}

on export and LaTeX will format it.  That works fine.  But in an index of names, 
if I want

{{{m(Denton, William)}}}

then Org takes that as two arguments to the macro, and outputs

\m{Denton}

Is there a way to get around this?

Thanks,

Bill

The comma needs to be backslash escaped.

{{{m(Denton\, William)}}}

Ref: (org) Macro Replacement

> (1) Since commas separate the arguments, commas within arguments have
to be escaped with the backslash character.  So only those backslash
characters before a comma need escaping with another backslash
character.

Aha!  Thanks to you and Eric for pointing this out.  I missed that footnote (and 
I should have tried escaping with a backslash anyway, since that's the solution 
to so many things).

I'd been looking at the documentation on the web site, as I usually do, but the 
pointer to the info page got me looking at that.  I'm going to start referring 
to it first and see how that goes.

You have to escape the , unfortunately:

{{{m(Denton\, William)}}}
