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.

scite module adds empty line at the end
by Wolfgang Schuster 26 Mar '20

26 Mar '20

Hi, when I use the scite module to format code blocks I get a empty line at the end of the environment. The cause for this is the "lines" environment used by the module which adds a \blank at the end. A custom lines environment without before/after values would help here. %%%% begin example \usemodule[scite] \setuptyping [TEX] [before=, after={\blank[back]}, after=] %\setuplines[after=] \starttext \ruledvbox\bgroup \startTEX \empty \stopTEX \egroup \stoptext %%%% end example Wolfgang

\tochar problem with symbols
by Wolfgang Schuster 10 Mar '20

10 Mar '20

Hi Hans, I encountered a nasty problem when I tried to make symbols for the Libertinus keyboard font. Whenever I tried to make a table with all symbols in the font ConTeXt stops with a error message. %%%% begin example \definefontsynonym [LibertinusKeyboard] [file:libertinuskeyboardregular.otf] \startsymbolset [libertinus-keyboard] [font=LibertinusKeyboard] % Libertinus Keyboard Regular \stopsymbolset \starttext \showsymbolset [libertinus-keyboard] \stoptext %%%% end example The error message is caused by two symbols in the font, the first is "bar" and the second is "dollar". The reason for this is that ConTeXt uses \tochar to auto create symbols in the font but \tochar set special catcodes for some letters. As can be seen in the example below "dollar" has catcode 3 and "bar" has catcode "13". %%%% begin example \starttext x\tochar{n:bar}|x \tochar{n:dollar}x$ \stoptext %%%% end example Wolfgang

Different Versions of Manuals
by Sebastian Miele 03 Mar '20

03 Mar '20

The ConTeXt Excursion referenced from the garden and contained in the LMTX distribution say that they are from 2017-Oct-05. The version linked from http://www.pragma-ade.com/overview.htm says it is from 1999-May-27. The ConTeXt reference manual linked from http://www.pragma-ade.com/overview.htm is from 2001-Nov-12. The version referenced in the garden is from 2013-Sep-27. As of now, I did not find a version of the document in the distribution. Neither in ConTeXt LMTX, nor in ConTeXt Standalone. In the following days I will start to use the most recent version of the two documents known to me. In the LMTX distribution: musings.pdf is from 2020-Jan-17, whereas musings.tex and musings-names.tex are from 2020-Feb-18. luametatex.pdf in LMTX is from Feb-18. In Standalone it is from Jan-30.
