Simple font size changes command
by josephcanedo＠gmail.com 13 Jun '16

13 Jun '16

Dear all, In a simple document using only 1 font but with different sizes what are the easiest switch commands to change font size locally ? I am aware of \tfa, \tfx etc …. but they do not seem to size in absolute size but rather relatively to current font size. In the following MWE : \starttext {\tfd Foo {\tfx Bar1}} {\tfx Bar2} Baz. \stoptext Bar1 is typeset much larger than Bar2. I’d look to write something like but don’t know who to get \BigSize and \SmallSize defined (and have Bar1 and Bar2 of same size) : {\BigSize Foo {\SmallSize Bar1}} {\SmallSize Bar2} Baz. Many thanks for any hint. Best regards Joseph Canedo

Math using sans serif font and problems with the alignment
by Freddy Omar López Quintero 10 Jun '16

10 Jun '16

Hello! Some days ago, I asked about how to use sans serifed font in all math document. My approach, given those answers, was create a little function to use the serif fonts in math (using \definestartstop) but, when there is some align involved, it produces an error :-\ . An example is the following: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \definefontfamily [mainface] [ss] [Latin Modern Sans] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:digitsnormal] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:digitsbold] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:uppercasenormal] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:uppercaseitalic] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:uppercasebold] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:uppercasebolditalic] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:lowercasenormal] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:lowercaseitalic] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:lowercasebold] \definefallbackfamily [mainface] [mm] [Latin Modern Sans] [preset=math:lowercasebolditalic] \definefontfamily [mainface] [mm] [Latin Modern Math] \definestartstop [formulass] [ before={\startformula \setupbodyfont[mainface]}, after=\stopformula ] \starttext abcdefg ABCDEFG 123456 i \startformula {\tf abcdefg\,ABCDEFG} \quad abcdefg\,ABCDEFG \quad 123456 \quad {\bf 123456} \stopformula % it works: \startformula Y=X\beta+\varepsilon \stopformula % it works: \startformulass Y=X\beta+\varepsilon \stopformulass % it doesn't work: \startformulass \startalign[n=4] \NC Y_t \NC = \beta_0 \NC + \beta_1 x_t \NC + \varepsilon_t \NR \NC Y_t \NC = \beta_0 \NC + \beta_1 x_t \NC + \varepsilon_t \NR \stopalign \stopformulass \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Could you please give me some advices?

Orphans and widows in Natural Tables
by Pavneet Arora 09 Jun '16

Related to my previous enquiry, I have the same issue with another part of the report card that uses Natural Tables. I'd like to keep two rows together as a unit, and not have the table split between them.

Specifying font style variant with \definefontfamily
by Pavneet Arora 09 Jun '16

09 Jun '16

I'm still a bit at a loss on how one goes about correctly specifying the variants in \definefontfamily using the default form given in the wiki. Usually adding "* Light", etc. is sufficient (see commented line using Junction font). (As an aside, is it also possible to combine \sc\bf? I haven't been able to figure that out). My application is using the (free) Andada font family, and I need to point the smallcaps style to the correct font (https://www.fontsquirrel.com/fonts/andada) In the following MWE I tried the following without success: 1. [sc=* SC Regular] 2. [sc=Andada SC Regular] 3. [sc=* SC-Regular] 4. [sc=Andada SC-Regular] All give the following (or similar) error to stdout: ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:121: attempt to index local 'file' (a nil value) stack traceback: ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:121: in function 'selectfont_savefile' ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:151: in function <...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:142> ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:526: in function 'registerfiles' ...ext/tex/texmf-context/tex/context/base/mkiv/font-sel.lua:567: in function 'action1' [string "local function scan1()..."]:55: in function <[string "local function scan1()..."]:42> 1 \definefontfamily[mainface][rm][Latin Modern] 2 >> \definefontfamily[mainface][rm][Andada][sc=Andada SC Regular] I end up finally settling on the form using the explicit file: [sc=file:AndadaSC-Regular.otf], which does work. But I really would like to understand how the first form as given in the wiki should be used properly? What patterns should I be looking for? An output of 'strings' on the font .otf file yields: "... with Reserved Font Name 'Andada'Andada SCRegular" "AndadaSC-Regular" advTHANKSance. >>>> MWE \definefontfamily[mainface][rm][Latin Modern] \definefontfamily[mainface][rm][Andada][sc=Andada SC Regular] %\definefontfamily[mainface][rm][Andada][sc=file:AndadaSC-Regular.otf] %\definefontfamily[mainface][ss][Junction][tf=* Light,bf=* Regular] \definefontfamily[mainface][ss][Fira Sans] \definefontfamily[mainface][tt][Inconsolata] \definefontfamily[mainface][mm][Latin Modern Math] \setupbodyfont[mainface,9pt] \starttext \sc Test of Small Caps. \stoptext <<<< MWE -- Pavneet Arora m: +1 (647) 406-6843 Waroc Informatik t: +1 (416) 937-9276

Wrong ToUnicode table for ZapfDingbats font
by Christoph Reller 09 Jun '16

09 Jun '16

Hi, Consider the following MWE, that displays a ZapfDingbats check mark: \definefontsynonym[ZapfDingbats][file:ZapfDingbats][features=dingbats] \definefont[zapfdingbats][ZapfDingbats] \starttext \getnamedglyphdirect{ZapfDingbats*dingbats}{a19} \stoptext In earlier versions, e.g., 2016.03.13, the font in the PDF contains a correct ToUnicode table with: ... 1 beginbfchar <0013> <2713> endbfchar ... In the currently newest version, 2016.06.08, the ToUnicode table lacks the entry for the check mark: ... 0 beginbfchar endbfchar ... Hence, the check mark cannot be copy pasted from the PDF. I fear this may be a bug. Or am I missing something? Any feedback is welcome. Christoph

beta
by Hans Hagen 08 Jun '16

08 Jun '16

Hi, I uploaded a new beta. This version has (experimental) support for color fonts. (not to be confused with 'coloring text in a font'). \definefontfeature[svg] [default][svg=yes] \definefontfeature[colored][default][colr=yes] % \definefont[Emoj][file:emojionecolor-svginot.ttf*default,svg] % \definefont[Emoj][file:seguiemj.ttf*default,colored] \definesymbol[bug1][\getglyphdirect{file:emojionecolor-svginot.ttf*svg}{\char"1F41B}] \definesymbol[bug2][\getglyphdirect{file:seguiemj.ttf*colored} {\char"1F41B}] \startTEXpage [width=10em,align=middle,offset=1em] There are several kind of bugs, like \symbol [bug1] and \symbol [bug2], also in \CONTEXT ! \stopTEXpage The colr features uses (if present) the overlay method (microsoft fonts have that) which is quite clean and efficient, while the svg one uses (when present) svg information from the font. Caching the later one will take some initial time (due to conversion, i might figure out something better) and needs inkscape installed. Attached an example. I didn't look too extensively for a font, but on the agenda is turning the cowfont in a color one (maybe for the ctx meeting). At some point I might add overloading of colors (for the overlay variant).

issue in the wiki
by Pablo Rodriguez 08 Jun '16

08 Jun '16

Dear list, modifying http://wiki.contextgarden.net/Command/hrule#Example, I added an "\hrule height .25in". I’m afraid that this command make all rules vanish in the final document. The same source compiles fine with latest beta (2016.05.22 15:18) on my laptop. Is there anything that I’m missing or have i hit a bug? Many thanks for your help, Pablo -- http://www.ousia.tk
