Can someone tell me if there's a compile command necessary for mkii? > 3) Conversely, even though I have "\sethyphenatedurlbefore -" and not > "\sethyphenatedurlafter -", there is a case where a URL is broken after > a hyphen (a hyphen that was already present in the URL): > http://www..../Niger- > Congo/... > and no case where a URL is broken before a hyphen. > Note that the "\sethyphenatedurlbefore -" setting is unchanged from the > original lang-url.mkii, so this is not an issue of needing to recompile. > > Maybe the general tex hyphenation mechanism is operating here, in spite > of the URL breaking settings. How do I override that (only for the URL)? Maybe it would help if someone could explain to me what 'normal' means in lang-url.mkii: \def\dohyphenatedurlnormal#1{\char#1\relax}% \def\dohyphenatedurlafter #1{\char#1\discretionary{}{\hyphenatedurlseparator}{}}% \def\dohyphenatedurlbefore#1{\discretionary{\hyphenatedurlseparator}{}{}\char#1\relax}% % 0=normal 1=before 2=after \def\sethyphenatedurlnormal#1{\expandafter\chardef\csname url @ #1\endcsname\zerocount} \def\sethyphenatedurlbefore#1{\expandafter\chardef\csname url @ #1\endcsname\plusone } \def\sethyphenatedurlafter #1{\expandafter\chardef\csname url @ #1\endcsname\plustwo } It looks like 'normal' means don't put a discretionary hyphenatedurlseparator before/after the character. Which would mean either (a) the url cannot be separated there (unless an adjacent character has hyphenatedurlbefore/after specified on it); or (b) the url will follow the same hyphenation rules as normal text (no special url-related rules). Can anyone tell me which it is? The definition of hyphenatedurl is: \unexpanded \def\hyphenatedurl#1% {\dontleavehmode \begingroup \the\everyhyphenatedurl \edef\ascii{#1}% \expanded{\handletokens{\detokenize\expandafter{\ascii}}}\with\dohyphenatedurl \endgroup} and the definition of \dontleavehmode is in syst-ext.tex with some comments: %D \macros %D {dontleavehmode} %D %D Sometimes when we enter a paragraph with some command, the %D first token gets the whole first line. We can prevent this %D by saying: %D %D \starttyping %D \dontleavehmode %D \stoptyping ... \unexpanded \def\dontleavehmode {\ifhmode\else \ifmmode\else \setbox\@@dlhbox\hbox{\mathsurround\zeropoint\everymath\emptytoks$ $}\unhbox\@@dlhbox \fi \fi} ... %D But, if you run a recent version of \TEX, we can use the new %D primitive: \ifx\normalquitvmode\undefined \else \let\dontleavehmode\normalquitvmode \fi I am running Xetex, FWIW. "This is XeTeX, Version 3.1415926-2.2-0.999.6 (Web2C 7.5.7)" The above makes me think that "dontleavehmode" should prevent any 'hyphenation' except for the types explicitly allowed in lang-url.mkii via \sethyphenatedurlafter/before/normal. Yet that isn't happening... it's breaking before slash instead of after, and after hyphen instead of before. I wondered briefly whether I had misinterpreted (swapped) the semantics of \sethyphenatedurlafter and \sethyphenatedurlbefore. But no, "\sethyphenatedurlbefore ." is working as expected: URLs break before a period. So I'm just puzzled. Thanks for any help...
