# ConTeXt: How to align a delimitedtext?

I'm using pandoc's default ConTeXt template, and it uses the following setup for blockquotes:

\setupdelimitedtext
[blockquote]
[before={\blank[medium]},
after={\blank[medium]},
indentnext=no,
align=middle
]


Then, any quoted text is entered as

\startblockquote
Quoted text
\stopblockquote


Now I want to have this quoted text centered on the page, but setupdelimitedtext does not seem to have that option (adding align=middle has no effect).

This surprises me, as it seems like a reasonable expectation, and makes me suspicious that perhaps I'm going about it all wrong. Is there a more ConTeXt-idiomatic way to do this?

Also, I can't find documentation for the setupdelimitedtext command in the ConTeXt manual. Is it been deprecated or something?

• delimitedtext does not provide the align key. (Even if it did, you need a comma after align=middle to get it to work). If you need a specific feature of delimitedtext, please send a feature request to the context mailing list to add align key to delimitedtext? If you just need middle alignment, then the following works: \definestartstop[blockquote][before={\blank[medium]\startmiddlealigned},after={\stopmiddlealigned\blank[medium]}]. – Aditya Jul 18 '14 at 22:46
• Unfortunately, this does align the text in the middle, but doesn't apply line breaks, so only a small fraction of my text is displayed. Inserting \crlf doesn't help. Any ideas? – mszep Jul 19 '14 at 7:41

You can change the alignment in a delimited text environment with the setup before={\setupalign[middle]}. What can be changed as well is to set the spacing around the environment with the spacebefore and spaceafter keys, the setting for spaceafter is only needed when you want a different value from spacebefore.

\setupdelimitedtext
[blockquote]
[spacebefore=medium,
%spaceafter=medium,
indentnext=no,
before={\setupalign[middle]}]

\starttext

\input knuth

\startblockquote
\input ward
\stopblockquote

\input zapf

\stoptext

• This works as well, and seems the most succinct, but I wonder if this is idiomatic, to use \setupalign in the middle of the document like that? Is the choice between before=\setupalign[middle] and before=\startalignment[middle], after=\stopalignment purely personal preference or are there some guidelines or issues I'm not aware of? The spacing issue is incidental, but thanks anyway for the tip :-) – mszep Jul 19 '14 at 19:38
• The \startalignment is a simple wrapper for the \setupalign command which starts a group before the alignment is changed to keep the changes local to the group. Because the blockquote environment already starts a local group before the \setupalign is used there is no need to use the \startalignment environment. – Wolfgang Schuster Jul 20 '14 at 8:29

Based on Aditya's comment, I've found something that works:

\definestartstop[blockquote][before={\blank[medium]\startalignment[middle]},
after={\stopalignment\blank[medium]}]


It'd be helpful to understand why \startmiddlealigned didn't work though...

• \startmiddleanligned...\stopmiddlealigned is equivalent to \midaligned{...}, so it typesets the content inside a \hbox, that does not split lines. – Aditya Jul 19 '14 at 15:12
• @mszep you wanted it, centered on the page. And you already said that it works. But I'm not quite sure with the above code, blockquote is centered on the page. – doed Jul 19 '14 at 17:53
• @doed I should have been more precise; I meant horizontally centered. Indeed, the above code centers the text horizontally, but not vertically, so the text does not necessarily appear in the middle of the page. – mszep Jul 19 '14 at 19:33
