Hi, the patch below makes it possible to change the interlinespace for blockquote etc. with the style key, e.g. \setupblockquote[style={\setupinterlinespace[...]}. The extra group is needed for the nextleft and nextright keys. \def\typo_delimited_start_par_indeed[#1]% {\let\typo_delimited_stop\typo_delimited_stop_par \edef\p_delimited_spacebefore{\delimitedtextparameter\c!spacebefore}% \ifx\p_delimited_spacebefore\empty \else \blank[\p_delimited_spacebefore]% \fi \delimitedtextparameter\c!before \iffirstargument \edef\m_delimited_argument{#1}% \fi \ifx\m_delimited_argument\empty \let\m_delimited_argument\m_delimited_argument \fi \ifx\m_delimited_argument\empty \endgraf \doadaptleftskip {\delimitedtextparameter\c!leftmargin}% \doadaptrightskip{\delimitedtextparameter\c!rightmargin}% \let\typo_delimited_stop_par_indeed\endgraf \else % backward compatible direct directive \startnarrower[\m_delimited_argument]% \let\typo_delimited_stop_par_indeed\stopnarrower \fi % so far \push_macro_checkindentation \useindentingparameter\delimitedtextparameter % \begingroup \usedelimitedtextstyleandcolor\c!style\c!color % + \begingroup \edef\p_delimited_left {\delimitedtextparameter{\c!left}}% \edef\p_delimited_right {\delimitedtextparameter{\c!right}}% \edef\p_delimited_nextleft {\delimitedtextparameter{\c!nextleft}}% \edef\p_delimited_nextright{\delimitedtextparameter{\c!nextright}}% % \leftdelimitedtextmark % \setnextleftdelimitedtextmark \setnextrightdelimitedtextmark % \typo_delimited_start_content} \def\typo_delimited_stop_par {\typo_delimited_stop_content \rightdelimitedtextmark + \carryoverpar\endgroup + \endgraf + \endgroup % new per 2013-01-21 ... please left floats - \carryoverpar\endgroup % new per 2013-01-21 ... please left floats \pop_macro_checkindentation \typo_delimited_stop_par_indeed \delimitedtextparameter\c!after \edef\p_delimited_spaceafter{\delimitedtextparameter\c!spaceafter}% \ifx\p_delimited_spaceafter\empty \else \blank[\p_delimited_spaceafter]% \fi \useindentnextparameter\delimitedtextparameter \aftergroup\dorechecknextindentation}% AM: This was missing!

Some hint on how linenumbering works in context
by Christoph Hintermüller 14 Apr '20

14 Apr '20

Hi After some struggling with xml exporter i have managed to get the output quit nicely including css and others. The only thing which still worries me a bit is the line numbering. While location set to left and not placing the content inside float environment, everything seems to be fine. So my question is. Is there besides codes any documentation how linenumber placement works inside context and how far the backend exporter hooks into this process at all? If codes only which source files should i read to understand how things work. And how things change between pdf and xml/xhtml export? Would help in deciding whether and how to place some hints inside the document to facilitate line numberplacing in export mode. Also let me know if this question is better placed on the ntg-context mailing list instead of the development mailing list Best Xristoph

data-vir.lua: Extra tracker
by Wolfgang Schuster 05 Apr '20

05 Apr '20

Hi, the following tracker has to be removed because a) there is a tracker with the same name in data-zip.lua and b) the file contains another tracker for trace_virtual. data-vir.lua (line 15): trackers.register("resolvers.locating", function(v) trace_virtual = v end) Wolfgang

Keep extreme tables on the same page as previous content
by Wolfgang Schuster 04 Apr '20

04 Apr '20

Hi, when you use extreme tables without a float environment but repeat the header the table always starts on a new page. %%%% begin example \starttext \samplefile{weisman} \blank \startxtable[header=repeat,split=repeat] \startxtablehead \startxrow \startxcell Table head \stopxcell \stopxrow \stopxtablehead \startxtablebody \dorecurse{100}{\startxrow \startxcell Table body \stopxcell \stopxrow} \stopxtablebody \stopxtable \stoptext %%%% end example The reason for this is the height set for the part of each page, on the first page ConTeXt uses a box with the height of \pagegoal forces a page break because the content doesn't fit. \setvalue{\??xtableflushsplit\v!repeat}% {\doloop {\clf_x_table_flush method {\v!split}% height \ifdim\pagegoal=\maxdimen\textheight\else\pagegoal\fi \relax \ifcase\c_tabl_x_state \exitloop \else \page \fi}} While determining the available space is easy we need a method to ensure the table stays on the page when the user adds a vertical skip (e.g. \blank[...]) before the table because this can lead to another page break.
