Possible bug: definetextbackground and grid layout
by Rik Kabel 05 Apr '14

05 Apr '14

The following example fails to compile, complaining "Missing { inserted." It compiles cleanly if one or more of the three marked lines are removed. This is the case with TL2013 and with recent standalone beta versions. I do not know if it ever worked. \setuplayout [grid=yes]% line one \definetextbackground[TB][ topoffset=.25em,bottomoffset=.25em,% line two location=paragraph,% line three ] \starttext \startTB prisca iuvent alios ego me nunc denique natum gratulor: haec aetas moribus apta meis. \stopTB \stoptext -- Rik

Line numbering in columns broken
by Jeremy Engel 05 Apr '14

05 Apr '14

In the latest beta (2014.04.03 16:20) there are updates to the line numbering system that break its function in columns. (In the past it didn't work at all in many situations, not it works but in a buggy way). In the example below, the line numbering passes over everything twice resulting in two overlapping numbers for each line. \starttext \startlinenumbering \startcolumns \input{knuth} \stopcolumns \stoplinenumbering \stoptext

[fontloader] does base mode support combining substitutions?
by Philipp Gesang 05 Apr '14

05 Apr '14

Hi Hans, when combining e.g. certain number substitutions like onum and pnum or tnum and lnum, node mode seems to work fine. However, those do have value in math mode as well which node mode does not currently support. For comparison, here is a test file: https://bitbucket.org/phg/lua-la-tex-tests/raw/93745dba31e23febb02191c039de… Is there a way to define a font with the combination of, say tnum and lnum that will work in math mode? If not, are there plans to implement it in the future? Best regards, Philipp

Metapost: I only need a little bit padding
by Jan Heinen 05 Apr '14

05 Apr '14

I want to have a rectangle (box) with a word in it (i.g. "Headline). And all should be rotated 90°. Below I found a solution I am quite happy with. How can I get a little bit more padding around the text in the box? You can copy the example to http://live.contextgarden.net/ - it is running: \startuseMPgraphic{rotatedHeadline} % Text "Headline" in a box which is rotated draw btex {\strut\tfd Headline} etex; % rectangle with rounded corners path p; p := llcorner currentpicture+(0mm,3mm){down}..{right}llcorner currentpicture+(3mm,0mm)-- lrcorner currentpicture+(-3mm,0mm){right}..{up}lrcorner currentpicture+(0mm,3mm)-- urcorner currentpicture+(0mm,-3mm){up}..{left}urcorner currentpicture+(-3mm,0mm)-- ulcorner currentpicture+(3mm,0mm){left}..{down}ulcorner currentpicture+(0mm,-3mm)--cycle; pickup pencircle scaled 0.5pt; clip currentpicture to p; draw p; currentpicture := currentpicture rotated 90; \stopuseMPgraphic \starttext \useMPgraphic{rotatedHeadline} \stoptext

Bugs in linenumbering ?
by Stéphane Goujet 05 Apr '14

05 Apr '14

Hello, Here is an example that highlights a few problems I have with linenumbering. When the line numbers are located in the margin, everything is fine. But when the number is located in the text: 1) Text overflows in the right margin. 2) Paragraph indenting does not work. We can even see a kind of right indentation appear. 1+2 => First line of the paragraph is too short, netx ones are too long. 3) linenumbering does not work within footnotes (neither with line numbers in margin nor in text). Perhaps (3) is not implemented, but I suppose (1) and (2) are not the expected behaviour. ============================== \setuppapersize[A4] \setupindenting[yes,first,medium] \definelinenumbering[lnbasic] \definelinenumbering[lntext] \definelinenumbering[lntextandnullwidth] \definelinenumbering[lntextandwidth] \setuplinenumbering[lnbasic][] \setuplinenumbering[lntext][location=text] \setuplinenumbering[lntextandnullwidth][location=text,width=0pt] \setuplinenumbering[lntextandwidth][location=text,width=.75em] \starttext {\bf A normal paragraph for reference}. \input tufte \startlinenumbering[lnbasic] {\bf Numbers in margin : correct right margin, paragraph indentation.} \input tufte \stoplinenumbering \startlinenumbering[lntext] {\bf Numbers in text, default width : overflow, no indentation of the first line but some kind of right indentation!} \input tufte \stoplinenumbering \startlinenumbering[lntextandnullwidth] {\bf Numbers in text, 0 width : no overflow but overtype on numbers, same problem with indentation.} \input tufte \stoplinenumbering \startlinenumbering[lntextandwidth] {\bf Numbers in text, average width : average overflow, same problem with indentation.} \input tufte \stoplinenumbering It also affects the previous lines when {em line numbering} starts from the middle of the line and not on a new paragraph. \startlinenumbering[lntext] {\bf Numbers in text, default width : overflow, no indentation of the first line but some kind of right indentation!} \input tufte \stoplinenumbering Line numbering does not work in footnotes\footnote{ \startlinenumbering[lnbasic] {\bf Numbers in margins.} \input tufte \stoplinenumbering } \footnote{ \startlinenumbering[lntext] {\bf Numbers in text.} \input tufte \stoplinenumbering }. \stoptext ============================== Goodbye, Stéphane.

bug with head in indices
by Pablo Rodriguez 04 Apr '14

04 Apr '14

Hans, I’m afraid that the last beta (from today) introduced a bug that prevents heads to be generated with indices. The minimal sample: \starttext \index{æ}ae \chapter{Index place} \placeindex %~ \completeindex \stoptext It doesn’t work either with \placeindex or \completeindex. Many thanks for your help, Pablo -- http://www.ousia.tk

label in Metapost
by Jan Heinen 03 Apr '14

03 Apr '14

Ten years ago I made a book with ConText and some Metapost. I made a circle and wrote the number into it: \startuseMPgraphic{Pagenumber} defaultfont := "pxb"; defaultscale := 1.5; fill fullcircle scaled 36pt withcolor .75white; numeric i; string pagex; i := PageNumber; pagenum = decimal i; label( pagenum, center currentpicture) withcolor black; \stopuseMPgraphic "label" does not write the number into the circle - years ago this was working. What changed in new Metapost? How can I get the number into the circle?
