Dear list,
The percent character in btx field is taken as a comment characters
which leads to the rest of the field being discarded. In the MWE
below, the URL is cut off at the % sign and everything after it is
lost.
Cheers, Henri

That is easily fixed by making \hyphenatedurl aware of \% being \letterpercent. \appendtoks \let\%\letterpercent \to \everyhyphenatedurl However, I wonder whether the treatment of % in bib files is correct, as regular BibTeX does treat the % verbatim. Because the following LaTeX example works just fine, with unescaped %. In my opinion this behaviour should be adopted by ConTeXt. \begin{filecontents*}{\jobname.bib} @misc{kraft, author = "Kraft, Nathan", title = "Mr Kraft's Virtual Filing Cabinet", year = "2015", url = "http://mrkraft.wikispaces.com/Mr+Kraft%27s+Virtual+Filing+Cabi net" } \end{filecontents*} \documentclass{article} \usepackage{apacite,url} \begin{document} \nocite{kraft} \bibliographystyle{apacite} \bibliography{\jobname.bib} \end{document} > > \startbuffer[references] > > @misc{kraft, > author = "Kraft, Nathan", > title = "Mr Kraft's Virtual Filing Cabinet", > year = "2015", > url = "http://mrkraft.wikispaces.com/Mr+Kraft\%27s+Virtual+Filing+C > abinet" > } > > \stopbuffer > > \usebtxdefinitions[apa] > \usebtxdataset[references.buffer] > > \starttext > > \nocite[kraft] > > \placelistofpublications > > \showbtxdatasetcompleteness > > \stoptext > > > > On Tue, 9 May 2017 09:44:01 +1200 > Henri Menke <henrimenke@gmail.com> wrote: > > > > > Dear list, > > > > The percent character in btx field is taken as a comment characters > > which leads to the rest of the field being discarded.

For Scribe compatibility, the database files allow an @COMMENT command; it’s not really needed because BibTEX allows in the database files any comment that’s not within an entry. If you want to comment out an entry, simply remove the ‘@’ character preceding the entry type. ... 14. LATEX’s comment character ‘%’ is not a comment character in the database files. From Tame the BeaST: New entries always start with @. Anything outside the “argument” of a “command” starting with an @ is considered as a comment. This gives an easy way to comment a given entry: just remove the initial @. As usual when a language allows comments, don’t hesitate to use them so that you have a clean, ordered, and easy-to-maintain database. Conversely, anything starting with an @ is considered as being a new entry. ---- There is a special entry type named @comment. The main use of such an entry type is to comment a large part of the bibliography easily, since anything outside an entry is already a comment, and commenting out one entry may be achieved by just removing its initial @. So bibtex has a funny way of dealing with comments, and do we really care about Scribe? We made the choice NOT to remain *strictly* bibtex compatible, after all bibtex is limited to ASCII 7-bit! The % comment is *universal* in TeX, Metapost, etc. so we chose to respect this, much stronger in my opinion, convention.

That's not true bibtex has no real problem with 8-bit-encodings, and works even quite often quite good with utf8 (when you don't try to use at places where it can be broken into parts. -- Ulrike Fischer http://www.troubleshooting-tex.de/ ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 9+ messages in thread

The buffer mechanism does not handle characters any differently than other text in the file, and % in a ConTeXt buffer has to be escaped if it does not signify a comment. If you specify an external (.bib or .bibtex) file to supply the data, % does not need to be escaped. So, this part is simple user error. (With \starttext \startbuffer abc%def ghi\%jkl \stopbuffer \getbuffer \stoptext you do not get %def in the output. Why do you expect different behavior if the buffer holds a bibtex entry?) The way hyphenatedurl handles things may well be worthy of improvement. -- Rik [-- Attachment #1.2: Type: text/html, Size: 1956 bytes --] [-- Attachment #2: Type: text/plain, Size: 492 bytes --] ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 9+ messages in thread

That is simply not true! Content inside ConTeXt buffers is as verbatim as reading an external file.
