Switching to righttoleft without changing margins of delimited text
Hi, I have the following example: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setupdelimitedtext[blockquote] [leftmargin=1.5em,rightmargin=0em,] \starttext \input knuth \startblockquote \input knuth \stopblockquote \startblockquote \righttoleft \input knuth \stopblockquote \input knuth \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \righttext seems to change the locations of the margins, i.e. leftmargin becomes rightmargin and vice-versa. That may be nice in some situations, but I need to keep the margins where they are. Is there a way to do this? (Maybe \righttoleft is the wrong command?) I thought I could define a new rtlblockquote with appropriate settings, like so: \definedelimitedtext[rtlblockquote] \setupdelimitedtext[rtlblockquote] [leftmargin=0em,rightmargin=1.5em,before={\righttoleft}] But maybe there's a better way. Any hints? Denis

Great, thanks, I'll wikify. Is that lmtx-only or will it work in mkiv?

But maybe there’s a better way. Any hints?
You switch directions when we're still in vertical mode, so you need:
\startblockquote
\dontleavehmode\righttoleft\ignorespaces
\input knuth
\stopblockquote
I'm afraid this doesn't give the desired result. While this fixes the inverted margins issue, this keeps the whole paragraph in LTR-mode. [cid:image002.jpg@01D7F0D9.6EFC58C0] The expected result (created with rtlblockquote) would be this: [cid:image004.jpg@01D7F0D9.6EFC58C0] So, the question remains: is a dedicated startstop-pair to achieve this (what’s the proper name of those anyway? In latex these are environments, but that feels odd in context)? Or are there easier solutions? Denis
