Is there a way to escape special characters in filenames passed to externalfigure. I'm encountering the situation where users are choosing images that may contain brackets or curly braces (e.g., flower[1].jpg or flower{1}.jpg). If I pass filename containing these characters directly to externalfigure, the closing bracket is mistaken for the end of the filename. \externalfigure[flower{1}.jpg] % works \externalfigure[flower[1].jpg] % doesn't work I then tried to define a variable that holds the filename and pass that variable to externalfigure, but it ran into problems with curly braces. \def\myimagefilename{flower[1].jpg} \externalfigure[\myimagefilename] % works \def\myimagefilename{flower{1}.jpg} \externalfigure[\myimagefilename] % doesn't work Does anyone have any idea how I could handle arbitrary filename inputs that contain brackets and curly braces? Cheers, Mike

If I understand your suggestion correctly, specifying name doesn't work. \externalfigure[][name=flower[1].jpg] \externalfigure[name=flower[1].jpg] Cheers, Mike -----Original Message----- From: ntg-context-bounces@ntg.nl on behalf of Hans Hagen Sent: Thu 12/27/2007 8:55 AM To: mailing list for ConTeXt users Subject: Re: [NTG-context] escaping filenames with externalfigure Santy, Michael wrote:

This did not work, the bracket after 1 is interpreted as the end for externalfigure and ConTeXt looks for a figure with the name "flower[1" but brackets in figure names could be used with \useexternalfigure.
I then tried to define a variable that holds the filename and pass that variable to externalfigure, but it ran into problems with curly braces.

Yould could define symbolic names for the figures and access the figures with this name, this allows you also to use bracketrs in the file names. \useexternalfigure[brace flower][flower{1}] \useexternalfigure[bracket flower][{flower[1]}] \starttext \externalfigure[brace flower] \externalfigure[bracket flower] \stoptext Wolfgang
Wolfgang,
Thanks for the suggestion. However, I'm using ConTeXt to typeset arbitrary XML input from users (and therefore arbitrary image filenames). While your idea works for the two examples that I gave, it doesn't work if the curly braces aren't balanced in the filename (e.g., "flower{1.jpg"). Is there any general character escaping mechanism for macro arguments?
Cheers,
Mike

If you use xml as input format you could save the file name in a temporary macro and use this macro now in the \externalfigure command. You already gave a example for this. Wolfgang

no time for a detailed answer now, but in xml mode you can make { } letters which solves the problem Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
Hans,

Could you please elaborate a bit? I'm not familiar with ConTeXt's XML mode (other than for processing MathML). One thing that I suspect is that XML mode would have an issue with '<' and '>' in the filenames. Another thought: The image filenames are encoded in my original xml documents according to RFC 1738 (http://www.blooberry.com/indexdot/html/topics/urlencoding.htm). In my XML -> ConTeXt XSL stylesheets I'm decoding those filenames. Would it be useful for others if the externalfigure could understand url encoded filenames similar to something like this: % % includes the file "flower{1.jpg" % \externalfigure[flower%7B1.jpg][encoding=rfc1738] This would give ConTeXt a general-purpose filename escaping mechanism.
