is there a simple TeX/ConTeXt way to test in a TeX file whether a link to an external document is broken so that I get an error message if not?
Quick and dirty:
\def\UseURL[#1][#2]{% \executesystemcommand{% if wget -qO/dev/null #2 \letterbar\letterbar [ -f #2 ]; then echo \letterbackslash\letterbackslash useURL[#1][#2]; else echo \letterbackslash\letterbackslash#1DoesNotExist; fi >texcmd.tmp}% \input texcmd.tmp}
\setupcolors[state=start] \setupinteraction[state=start]
\UseURL[fileOk][/tmp/real-file] \UseURL[fileNotOk][/tmp/not-existing-file] \UseURL[urlOk][http://contextgarden.net/] \UseURL[urlNotOk][http://no.contextgarden.net/]
\starttext existing file: \from[fileOk]
not existing file: \from[fileNotOk]
existing url: \from[urlOk]
not existing url: \from[urlNotOk] \stoptext
Cheers, Peter
