[font-chk.lua] missing glyph tracker
by Philipp Gesang 20 Jun '13

20 Jun '13

Hi Hans, in font-chk.lua, the function checkers.missing fails to assign the var “lastfont”, leading to a meaningless test for equivalence with “font”. See patch below. Also, may I ask you to include the unicode character in the tracker message? This would make the output more legible, imo. Something like this (line 71): - report_fonts("char %U in font %a with id %a: %s",char,tfmdata.properties.fullname,font,message) + report_fonts("char %U (%s) in font %a with id %a: %s",char,utf.char(char),tfmdata.properties.fullname,font,message) Best regards, Philipp --- font-chk.lua.orig 2013-06-20 13:46:56.282164831 +0200 +++ font-chk.lua 2013-06-20 13:47:15.224965072 +0200 @@ -210,6 +210,7 @@ local char = n.char if font ~= lastfont then characters = fontcharacters[font] + lastfont = font end if not characters[char] and is_character[chardata[char].category] then if action == "remove" then

background color for makeups
by Pablo Rodríguez 19 Jun '13

19 Jun '13

Dear list, the only way I found to center content horizontally and vertically on a page is a makeup, such as: \startstandardmakeup[align=middle] content to be centered \stopstandardmakeup I need to be able to change the background on some given pages. Which is the way to do this? I have tried with (what I understand from) setups: \startsetups[setups:redcolor] \setupbackgrounds[page][background=color,backgroundcolor=red] \stopsetups \startstandardmakeup[setups=setups:redcolor] content \stopstandardmakeup But it didn't work. Could you help me with this? Many thanks for your help, Pablo -- http://www.ousia.tk

luajittex not able to find some fonts
by Pablo Rodríguez 19 Jun '13

19 Jun '13

Dear list, I wonder whether this would be interesting to the luajittex developers, but for some strange reason when I invoke context with --engine=luajittex, only some system fonts are found. My guess is that with luajittext the most recently installed system fonts aren't the ones not found. Just in case it might help, Pablo -- http://www.ousia.tk

item bullet processing / font problem
by hwitloc＠gmail.com 19 Jun '13

19 Jun '13

Setting the main font to ipaexm for Japanese characters, causes the sample document below to fail being typest properly. The $\diamond$ symbol I specified as an item bullet does not get typeset and where is should be is blank. Though not shown in this example, the default set is also affected. When it should be a circular bullet a largish hypen - is displayed. Also parsing of the document text itself is affected with Context halting in the middle of the first item's text. I think all problems are due to the change in fort. Is there anyway I can specify a backup font or a fort to use for only the symbols, which I believe is in a math font? Any assistance it getting this working will be much appreciated. Thank you. ---- # 1 Sample Context Macro document that causes the errors: ---- \usemodule[simplefonts] \setmainfont[ipaexm] \definesymbol[5][$\diamond$] \starttext \startitemize[5,columns,unpacked,two,broad] \item 此の行にbulletを打つ。 \item One more column for good measure \stopitemize \stoptext --- end of sample Context macro doc. ---- #2 sample of the errors output by Context ---- system > cont-new.mkiv loaded ... system > beware: some patches loaded from cont-new.mkiv . . fonts > latin modern fonts are not preloaded languages > language en is active loading > ConTeXt User Module / Simplefonts fonts > typescripts > unknown: library 'loc' {/usr/local/texlive/2012/texmf-....../context/mkiv-base.map} fonts > defining > forced type otf of latinmodernmath-regular not found fonts > defining > font with asked name 'latinmodernmath-regular' is not found using lookup 'file' fonts > defining > unknown font latinmodernmath-regular, loading aborted fonts > defining > unable to define latinmodernmath-regular.otf as [simplefonts:1-12pt-mm-mr--3] fonts > defining > forced type otf of latinmodernmath-regular not found fonts > defining > font with asked name 'latinmodernmath-regular' is not found using lookup 'file' fonts > defining > unknown font latinmodernmath-regular, loading aborted fonts > defining > unable to define latinmodernmath-regular.otf as [simplefonts:1-12pt-mm-mr--2] . . fonts > math: unset for global bodyfont simplefonts:1 at 12pt fonts > math: unset for global bodyfont simplefonts:1 at 12pt !

Referencing problem (correction)
by Robert Blackstone 19 Jun '13

19 Jun '13

Sorry for the mistake: I wrote one \ too many so that I unwittingly created an absurd link. The message was supposed to be this: Hi all, To include in a text several graphics that for some reason must have the same figure number (with suffixes .a, .b etc.), I use \startplacefigure[location=here,reference=,title={},group=,groupsuffix=] {\externalfigure[]} \stopplacefigure an experimental solution that Hans gave me in april (Ref. ntg-context Digest, Vol 106, Issue 4, Date:14 April 2013) and which works perfectly. My problem is: how can I refer in my text to this set of figures (instead of to the separate figures). I have tried to use "group" as the label for referencing, as it is the only argument that all figures have in common, but my trials failed and I have no idea how to accomplish this. (The wiki is too vague for me on this point.) Thanks in advance for any help. Regards, Robert Blackstone

Orphans and Windows
by Malte Stien 19 Jun '13

19 Jun '13

G'day everyone, I use introductory sentences to numbered lists all the time, like this (where \startnlist...\stopnlist is a custom itemised list): To remove a foo from a pool of foos: \startnlist \item Do this... \item Do that... \item ...and so on... \stopnlist On occasions, I am getting that introductory sentence as an orphaned line at the end of a page and my numbered list as the first thing on the next page. How can I avoid that? There is not much about orphans and widows on the Wiki or in the reference manual. Thank you, Malte. -- “The Electric Monk was a labour-saving device, like a dishwasher or a video recorder...

[***SPAM***] Scaling large (annotated) MetaFun drawing
by Pavneet Arora 18 Jun '13

18 Jun '13

[Sorry about the previous null message.] Background: Typically I use MetaPost to create small figures, which I then can scale as needed in larger documents. These figures contain no text so I can simply use the .eps output of mpost as an inclusion. Recently, I have embarked on a large illustration replete with lots of text labels. It is a "distilled" architectural drawing intended for diagnostic and maintenance purposes. In it plumbing details are overlaid over a layout. For simplicity, I standardized on unit size of 1cm so that co-ordinates can easily map from physical dimensions with the unusual hybrid scale of 1cm=1ft ;).. Status: With this set unit size, my drawing has grown very large. My intent is to get it printed on one of the (U.S.) based architectural paper sizes, or if it can be made legible on U.S. Tabloid size paper (17" x 11").. My first successful approach (and where I stand right now) is to simply use \startMPpage and \stopMPpage to scale to the page. Thera are a couple of issues, though, with this approach. First, I want to add additional information to the page, other than what would be handled by MetaPost, e.g., some tables, etc. Even without this additional information, having the drawing scale to page size does not give adequate margin buffering and if there are some labels right at the edge, I have seen some clipping of the text. Objective: I would like to create a scalable drawing with all of its text labels so that I can scale appropriately to different page sizes, and also incorporate the illustration with other document elements. >From what I have read at: http://wiki.contextgarden.net/MetaPost_in_ConTeXt I think what I need is something akin to \startuseMPgraphic with a scaling option if I want to include the code inline. Otherwise, the drawing is clipped on the page. Or perhaps I simply try to convert the existing PDF output to PS, and then include it? What I am hoping is to get a best practises workflow from the list so that I can simply adopt it. advTHANKSance. Sample: A MWE is found below: \setuppapersize[tabloid,landscape][tabloid,landscape] \starttext \setupMPinstance [metafun] [extensions=yes, initializations=yes, textstyle=bold] \startMPpage u:=1cm; pickup pencircle scaled 1pt; draw (5u,0u) {dir 90}..(0u,5u) {dir 180}; draw (0u,5u) .. (-1.5u,10.5u) {dir 90} .. (0u,16u); draw (0u,16u) {dir 0} .. (5u,21u) {dir 90}; draw (5u,21u) -- (39u,21u); draw (39u,21u) {dir 270} .. (42u,18u) {dir 0}; draw (42u,18u) .. (43.5u,10.5u) {dir 270} .. (42u,3u); draw (42u,3u) {dir 180} .. (39u,0u) {dir 270}; draw (39u,0u) -- (35u,0u); draw (35u,0u) .. (22u,3u) {dir 180} ..

NTG-context] How to hack the lua files
by Lance Larsen 18 Jun '13

18 Jun '13

I haven't been using the project structure. From your question, I am inferring that this might help. At present I have treated the files as two separate documents. I didn't take too much time looking at how to set up the project structure because it wasn't clear that I needed it. But I can see how this might impact cross references between documents. -Lance On 6/17/2013 3:25 PM, Lance Larsen wrote: > Hans, > > Thankyou for your suggestion of using the \usereferences tag to reference > formulas in another document.

placing an xtable
by Pablo Rodríguez 18 Jun '13

18 Jun '13

Dear list, I'd like to place a table centered (both horizontally and vertically) on an empty page. Is there no option from the xtable itself to achieve that? I have tried \startxtable[location=lohi], but this doesn't seem to affect to the placement of the table itself. Many thanks for your help, Pablo -- http://www.ousia.tk
