Concatenate buffers without newline
by Pascal Pascali 22 Jun '21

22 Jun '21

Hello! Is there a way to concatenate predefined blocks or buffers without ConTeXt printing newlines between them? I'd like to have something like: \startBitOfData [name1] Some part of paragraph here. \stopBitOfData \startBitOfData [name2] Some more going on here. \stopBitOfData And then: \getBitOfData [name1] \getBitOfData [name2] Outputting: Some part of paragraph here. Some more going on here. Not outputting: Some part of paragraph here. Some more going on here. Thank you for any tip! Best regards, Pascal

Re: [NTG-context] simplifying repeated macro calls in metafun

Dear Otared, I received list mail in condensed form, I didn’t see your mail before I sent one. As Mikael explained, “whatever” is very nice to find the intersection point of two lines. You can see nice examples which use “whatever” in MetaFun manual. In my code, the next point is the intersection point of the edge and the folding line which bisect the angle of the former folding line [M,N]. H := whatever[N, N + dir(.5*angle(M-N))*u] = whatever[A,B]; Enjoy the use of “whatever”! I made an animation of the folding process using animation module and \processMPbuffer. But Woldgang’s code showed a way to make it using \startuseMPgraphic. Best regards, Dalyoung

simplifying repeated macro calls in metafun
by Jeong Dal 21 Jun '21

21 Jun '21

Hi, I defined a macro definition in metafun, and draw figures using \startbuffer[] … \stopbuffer and \processMPbuffer[]. As you see in the attached code, the same macro definition is used repeatedly by changing the numeric argument. Is there a better way to simplify the code, for example, using \dorecurse and recurselevel? Thank you for reading. Best regards, Dalyoung \startbuffer[UDBasic] pair A,B,C,D; pair E, F, G, H; path p,q; numeric ang,maxNum; u:=1in; A=(.95*TextWidth,u); B=(0,u); C=(0,0); D=(.95*TextWidth,0); p := A--B--C--D; q := (TextWidth,1.5u)--(0,1.5u)--(0,-.5u)--(TextWidth,-.5u)--cycle; z0=(.1u,0); vardef nextPt (expr M,N) = if ypart(N) = 0: H := whatever[N, N + dir(.5*angle(M-N))*u] = whatever[A,B]; else: H := whatever[N, N + dir(.5*angle(M-N))*u] = whatever[C,D]; fi; H enddef; def grayUD(expr i) = draw G -- if ypart(B)=ypart(G): B -- C else: C -- B fi --z[i]; filldraw z[i]+2*(G-z[i])*u -- z[i] -- z[i+1] -- z[i+1]+(G-z[i])*u -- cycle withcolor .75white; draw G -- z[i+1] dashed evenly; draw z[0] for k=0 upto i: --z[k] endfor dashed evenly; clip currentpicture to q; enddef; def linesUD(expr i) = draw p; draw z0 for k=0 upto i+1: --z[k] endfor dashed evenly; setbounds currentpicture to boundingbox q; enddef; \stopbuffer \startbuffer[UDpts] ang := 40; z[1] = whatever[z[0], z[0]+dir(ang)*u] = whatever[A,B]; G := whatever[z[0], z[0]+dir(2*ang)*u] = whatever[A,B]; for k = 2 upto 20: z[k] = nextPt(z[k-2],z[k-1]); maxNum := k; exitif xpart(z[k]) > TextWidth; endfor; \stopbuffer \startbuffer[UD0] draw p; setbounds currentpicture to boundingbox q; \stopbuffer \startbuffer[UD1] grayUD(0); \stopbuffer \startbuffer[UD11] linesUD(0); \stopbuffer \startbuffer[UD2] G := z0; grayUD(1) \stopbuffer \startbuffer[UD21] linesUD(1); \stopbuffer \startbuffer[UD3] G := z1; grayUD(2); \stopbuffer \startbuffer[UD31] linesUD(2); \stopbuffer \startbuffer[UD4] G := z2; grayUD(3); \stopbuffer \startbuffer[UD41] linesUD(3); \stopbuffer \startbuffer[UD5] G := z3; grayUD(4); \stopbuffer \startbuffer[UD51] linesUD(4); \stopbuffer \startbuffer[UDFinal] draw p; draw z0--z1--z2--z3--z4--z5--z6--z7--z8 dashed evenly; setbounds currentpicture to boundingbox q; \stopbuffer \starttext \processMPbuffer[UDBasic,UDpts,UD0] \processMPbuffer[UDBasic,UDpts,UD1] \processMPbuffer[UDBasic,UDpts,UD11] \processMPbuffer[UDBasic,UDpts,UD2] \processMPbuffer[UDBasic,UDpts,UD21] \processMPbuffer[UDBasic,UDpts,UD3] \processMPbuffer[UDBasic,UDpts,UD31] \processMPbuffer[UDBasic,UDpts,UD4] \processMPbuffer[UDBasic,UDpts,UD41] \processMPbuffer[UDBasic,UDpts,UD5] \processMPbuffer[UDBasic,UDpts,UD51] \processMPbuffer[UDBasic,UDpts,UDFinal] \stoptext

Trying to make all links in my document blue instead of red or green
by T. Kurt Bond 21 Jun '21

21 Jun '21

I'm trying to make all the hyperlinks in my document blue. Here's my example: \setupinteraction [state=start, color=blue, contrastcolor=blue ] \starttext \completecontent \section{Section A} \subsection{SubSection A.A} \pagebreak[yes] \section {Section B — on another page} \subsection {SubSection B.A — on another page} \stoptext When I format it with ConTeXt (ConTeXt ver: 2021.06.18 23:37 LMTX fmt: 2021.6.19 int: english/english) links to destinations on the same page come out black while links to destinations on another page come out blue, as I'd intended. Here is a screen shot: [image: image.png] Notice that the Contents lines with Section A and SubSection A.A are black? I'd expected them to be blue. -- T.

\pdfbackendcurrentresources not expanded
by Christoph Reller 21 Jun '21

21 Jun '21

Hi, Consider the following MWE, which uses the tizk module: \usemodule[tikz] \usetikzlibrary[fadings] \starttext \starttikzpicture \fill [path fading=west,red] (-1,-1) rectangle (1,1); \stoptikzpicture \stoptext When compiling with ConTeXt LMTX version 2021.06.18, the output PDF contains "\pdfbackendcurrentresources" in the middle of a resource dictionary. Apparently, this command does not get expanded but is written literally to the file, which makes the PDF corrupt. This command is used in the tikz module file pgfutil-context.def as: \def\pgf@sys@pdf@possible@resources{\pdfbackendcurrentresources} As mentioned in a comment in back-pdf.mkxl, the command is implemented in lua in lpdf-ini.lmt. The command is also used in mlib-pps.mkxl and is documented in ConTeXts interface. Can somebody tell why it is not expanded? Any help is appreciated. Cheers, Christoph

Font glyph replacement regression
by Christoph Reller 21 Jun '21

21 Jun '21

Hi, In my documents I use the MyriadPro font of Adobe. Until recently, some glyphs were automatically replaced (in a correct way) for this font. In ConTeXt LMTX version 2021.09.18, the replacement stopped working: 1. En dash and em dash: "--" and "---" are not by default replaced any more. Using the font feature "trep" brings back the replacement in this case. See https://www.mail-archive.com/ntg-context@ntg.nl/msg98162.html 2. Apostrophe: "'" is not replaced by the proper apostrophe anymore. Unfortunately, I don't know any font feature to bring back this replacement. Any hints for this issue? (I can provide the MyriadPro font for debugging purposes.) Cheers, Christoph

Natural tables framecolor=white regression
by Christoph Reller 20 Jun '21

20 Jun '21

Hi, Consider the following MWE: \starttext \setupTABLE[ rulethickness=5pt, framecolor=white, %red, background=color, backgroundcolor=gray, frame=off] \setupTABLE[1][2][foregroundcolor=white, topframe=on] \setupTABLE[r][2][topframe=on] \bTABLE[setups=table:color] \bTR \bTD One \eTD \bTD A \eTD \eTR \bTR \bTD \rotate[rotation=90]{Two} \eTD \bTD B \eTD \eTR \eTABLE \stoptext Attached is the result for ConTeXt LMTX version 2021.04.09 (and earlier) and for version 2021.06.18. In the latter case, the white frame is missing in the first column between row 1 and 2. Changing the frame color to red, makes the frame appear. Could this be a bug or am I doing something wrong? Thank you for looking into this. Cheers, Christoph

Functionnames disappearing (sometimes)
by Mikael Sundqvist 20 Jun '21

20 Jun '21

Hi, I noticed something strange today. If I use computer modern unicode (the concrete font) together with Neo Euler math then sometimes function names (like \sin, \cos, \tan) disappear. Sometimes they show (in non-displayed math and in fractions(?)). Attached is a file showing the problem, together with the output and the typescript file. I use the latest ConTeXt version and I have cleared the cache, but no change. Maybe I'm overlooking something, but what? /Mikael

Modify ToUnicode with Goodies
by Christoph Reller 20 Jun '21

20 Jun '21

Hi, On Windows, we have the consola font. Consider the MWE: \starttext \definedfont[name:consola*default at 12 pt] - \stoptext The output PDF is correctly generated with recent versions of ConTeXt LMTX. The hyphen is, however, mapped to a soft hyphen <https://unicode-table.com/en/00AD/> by means of the ToUnicode table which contains: beginbfchar <015E> <00AD> endbfchar Consequently, when copying the text from the PDF and pasting in an editor or a console, the soft hyphen is pasted. I would like to change the ToUnicode information to an ordinary hyphen-minus <https://unicode-table.com/en/002D/>: beginbfchar <015E> <002D> endbfchar I have tried with a goodies file, and an updated MWE: --- 8< ------------------------------------------ return { name = "consola", version = "1.00", comment = "", author = "", copyright = "", remapping = { tounicode = true, unicodes = { hyphen = 0x002D, }, }, } --- 8< ------------------------------------------ \definefontfeature[consola][mode=base, goodies=consola, unicoding=yes] \starttypescript[mono][consolas] \definefontsynonym[ConsolasRegular][file:consola][features=consola] \stoptypescript \starttypescript[mono][consolas] \definefontsynonym[Mono][ConsolasRegular] \stoptypescript \definetypeface[Body][tt][mono][consolas][default] \setupbodyfont[Body, ss, 10pt] \starttext \tt - \stoptext --- 8< ------------------------------------------ Unfortunately, this has no effect. Please tell me how to correctly update ToUnicode information with a goodies file. Cheers, Christoph
