Difference between \skip and \unskip
Hullo, can someone tell me what's the difference between \skip and \unskip and when to use them? I've already checked the wiki and the references, but cannot find a definition of either. Here's a use case that's giving me headaches for quite some time: In my bibliography I often have items that are missing one or two fields (e.g. legal texts with or without amendments etc.) and I have to tell ConTeXt to skip those. From trial and error I learnt that: * \skip leaves me with the punctuation and styling around the skipped field (e.g. a trailing ", ." or "( )") * \unskip seems to do what I want, but generates the following error every time 'context' reaches an '\unskip' entry: --8<------------------ l.1 ...al , št. \localissue /\localvolume \skip , \localspremembe . \currentnotedescriptiontext ...ptionnumberentry )} \handlenoteitself ... \currentnotedescriptiontext \endstrut \dostopstoreddes... \handlenoteinsert ...s }\handlenoteitself {#1}{#2} \egroup \the \everyafterno... \@@notemakedescription ...note \currentnotenumber \fi \fi \endgroup \fi \fi ... ... l.82 ...e Konvencija MOD št. 173\zakon[][MOD_173] (ter Priporočilo št. 18... ? help A number should have been here; I inserted `0'.

no, it’s about adding and removing space between words Wolfgang

Oh, OK. :\ So, how do I skip missing bibliography fields and characters besides spaces that are part of the citing style? Cheers, Matija -- gsm: +386 41 849 552 www: http://matija.suklje.name xmpp: matija.suklje@gabbler.org

You saved the values here in macros: \def\zakon[#1][#2]% {\doifdefinedelse{zakonkratko:#2} {\zakonkratko[#1][#2]} {\bgroup \nocite[#2]% \getcitedata[title][#2] to \localtitle \getcitedata[kratko][#2] to \localkratko \getcitedata[journal][#2] to \localjournal \getcitedata[issue][#2] to \localissue \getcitedata[volume][#2] to \localvolume \getcitedata[spremembe][#2] to \localspremembe \footnote{\localtitle\ (\localkratko), \localjournal, št. \localissue/\localvolume\skip, \localspremembe.}% \egroup}% \setvalue{zakonkratko:#2}{done}} You can check for content in these macros with: \doifsomething{\localtitle}{\localtitle} \doifsomethingelse{\localtitle}{\localtitle}{<something else>} \doifnothing{\localtitle}{<no title>} \doifelsenothing{\localtitle}{<no title>}{\localtitle} Wolfgang

But this is what the macros \setuppublicationlayout and \insertXYZ are already doing, right? Wouldn't it be easier to use those? Or is the problem that something needs to be cited multiple times (once in footnote and then again at the end of article)? Mojca

Each entry has to cited twice, yes — first in a shorter form in the footnote and then in the full form in the publications list at the end of the document. Cheers, Matija -- gsm: +386 41 849 552 www: http://matija.suklje.name xmpp: matija.suklje@gabbler.org

Adjust the style? Certainly that is easier than the macro solution I see below.

The style is prescribed by the faculty, so that's not really an option. :\ Cheers, Matija -- gsm: +386 41 849 552 www: http://matija.suklje.name xmpp: matija.suklje@gabbler.org

No I was going to propose to adjust the bibliography style, but if you need it both inline and at the end, that does not work. As Wolfgang wrote already, macros like \doifsomethingelse{\localtitle}{\localtitle}{<something else>} are the most important key to getting the formatting right. Best wishes, Taco

Oh, OK. Will try something there (also Mojca was kind enough to take a look at a full example). Yes, two different citing styles — 1) footnote; 2) end of text — are needed and that complicates the matters immensely.
As Wolfgang wrote already, macros like
\doifsomethingelse{\localtitle}{\localtitle}{<something else>}
are the most important key to getting the formatting right.
Will take a look and bug you if I don't figure it out, thanks. Cheers, Matija -- gsm: +386 41 849 552 www: http://matija.suklje.name xmpp: matija.suklje@gabbler.org
