Dear all, Presently I'm experiencing a problem with urls that, hopefully, the ME will demonstrate. It seems to me that something must have changed in the source since the end of september. The example works with mkiv of 24 sept, but not with that of 3 november and later. --------------------------------------------------- \useURL[apurl][http://wiki.contextgarden.net/Category:Commands] \starttext \from[apurl] \url[apurl] \stoptext -------------------------------------------- I use TeXshop. The console gives me the following cryptic message about a LuaTeX error: \ctxcommand #1^^@-\directlua {commands.#1} \font_helpers_low_level_define ...caledfontmode )} \edef \somefontspec {at \n... \font_helpers_trigger_define ..._identifier_class \csname \v_font_identifier… \applyfontclassstrategies ...\fontface \endcsname \else \expandafter \font_h... \font_helpers_synchronize_font ...classstrategies \fi \setfalse \c_font_auto... \tt f-\ifmode \mathtt \else \normaltt \fi … l.5 \from[apurl] ? Thanks in advance for any help. Best regards, Robert Blackstone
