Note that there is a free and very good PDF accessibility checker: http://www.access-for-all.ch/en/pdf-lab/pdf-accessibility-checker-pac.html You can easily generate a detailed report with this tool. It does, however, not check for PDF/A-1a conformance. Cheers, Christoph

Counter[way=bypage] bug in latest beta?
by mf 30 Jun '15

30 Jun '15

Hello list, consider this example, involving a number (counter) to be reset at each page: \starttext \definenumber[MyNumber][way=bypage] % MyNumber=0 \incrementnumber[MyNumber] % MyNumber=1 \incrementnumber[MyNumber] % MyNumber=2 mynumber is \rawcountervalue[MyNumber]. % prints 2 \page % MyNumber=0 \incrementnumber[MyNumber] % MyNumber=1 At the new page, mynumber is \rawcountervalue[MyNumber]. \stoptext In ConTeXt 2014.05.21 22:04 (the one I get as Debian package) it works as expected, giving MyNumber=1 at page 2, because MyNumber gets reset at page break. In the latest beta (and also in 2014.04.01) the counter does not reset and it's equal to 3 at the end of page 2. Another question: when you comment out the increment at page 2, the counter does not reset, and you get 2 even in version 2014.05.21. \starttext \definenumber[MyNumber][way=bypage] % MyNumber=0 \incrementnumber[MyNumber] % MyNumber=1 \incrementnumber[MyNumber] % MyNumber=2 mynumber is \rawcountervalue[MyNumber]. % prints 2 \page % MyNumber=0 % \incrementnumber[MyNumber] COMMENTED OUT At the new page, mynumber is \rawcountervalue[MyNumber]. % prints 2 \stoptext Is this a bug or is it the way it should work when you don't increment it?

\setuphead[part] - special look
by Procházka Lukáš Ing. - Pontex s. r. o. 29 Jun '15

29 Jun '15

Hello, I'm trying to \setuphead[part] to have the following features: 1. Part head to fill the whole page. 2. Part number and name to be placed (approx.) in the golden ratio of the page. 3. Page background (for the \part only!) to be colored, e.g. blue. ---- \define[2]\MyPartCmd{% {% \vbox to\vsize{% \vfill\vfill% #1 \blank[big] #2 \vfill\vfill\vfill% } }% } \define[1]\MyPartCmdText{% \hbox to\hsize{\hfill \bf DĂl #1\hfill}% } \definefontsize[e] \definebodyfontenvironment[default][e=5.] \define[1]\MyPartCmdNum{% \hbox to\hsize{\hfill \bfe\sc#1\hfill}% } \setuphead[part] [command=\MyPartCmd, numbercommand=\MyPartCmdText, textcommand=\MyPartCmdNum, placehead=yes,header=none,page=odd, before={\setupbackgrounds[page][background=color,backgroundcolor=blue,state=start]}, %after={\setupbackgrounds[page][background=]}, ] \starttext \showboxes \part{Part} \input knuth \stoptext ---- The code above doesn't satisfy the features: Ad 1: Some text (from knuth) appears in the bottom (should be solved by "after=\page", but is there a better solution, e.g. to affect height of the \vbox in \MyPartCmd?) Ad 3: I'm able to make only the part page blue (now all pages are blue; when I uncomment "after={\setupbackgrounds[page][background=]},", no page is blue). Could anyone help me to "tune" the \setuphead[part]? Thank you in advance. Best regards, Lukas -- Ing.

Testing the value of a number defined with \definenumber
by mf 27 Jun '15

27 Jun '15

I'd like to test the value of a number (\definenumber). \starttext \definenumber[numero][] \setnumber[numero][42] The value of {\tt numero} is \getnumber[numero]. \doifelse{\getnumber[numero]}{42}{ Ok, the test worked. }{ Why does not it work? } \stoptext ConTeXt types "Why does not it work?", because the test fails. Why?

Virtual font question
by Zhichu Chen 24 Jun '15

24 Jun '15

Hello list, I was trying to use the Math Times Pro 2 fonts in ConTeXt MKIV. This Type1 font contains a map file, a set of pfb files and the corresponding tfm files. I was managed to write a .lfg file and a type-imp-xxx file, but here's my problem. The font comes with three different sizes, the virtual fonts in my .lfg file look like: =================================================================== virtuals = { ["mtpro06a-regular"] = { { name = "file:texgyretermes-regular.otf", features = "virtualmath", main = true }, { name = "mt2mif.tfm", vector = "mtpro2-mi", skewchar=0x7F }, { name = "mt2syf.tfm", vector = "mtpro2-sy", skewchar=0x30, parameters = true }, { name = "mt2mbf.tfm", vector = "mtpro2-mb", skewchar=0x7F }, { name = "mt2syaf.tfm", vector = "mtpro2-sya", skewchar=0x7F }, { name = "mt2bbf.tfm", vector = "mtpro2-bb", skewchar=0x7F }, { name = "mt2msf.tfm", vector = "mtpro2-mca", skewchar=0x7F }, { name = "mt2bmsf.tfm", vector = "mtpro2-bmca", skewchar=0x7F }, { name = "mt2mff.tfm", vector = "mtpro2-mfa", skewchar=0x7F }, { name = "mt2bmff.tfm", vector = "mtpro2-bmfa", skewchar=0x7F }, { name = "mt2bbif.tfm", vector = "mtpro2-bbi", skewchar=0x7F }, }, ["mtpro08a-regular"] = { { name = "file:texgyretermes-regular.otf", features = "virtualmath", main = true }, { name = "mt2mis.tfm", vector = "mtpro2-mi", skewchar=0x7F }, { name = "mt2sys.tfm", vector = "mtpro2-sy", skewchar=0x30, parameters = true }, { name = "mt2mbs.tfm", vector = "mtpro2-mb", skewchar=0x7F }, { name = "mt2syas.tfm", vector = "mtpro2-sya", skewchar=0x7F }, { name = "mt2bbs.tfm", vector = "mtpro2-bb", skewchar=0x7F }, { name = "mt2mss.tfm", vector = "mtpro2-mca", skewchar=0x7F }, { name = "mt2bmss.tfm", vector = "mtpro2-bmca", skewchar=0x7F }, { name = "mt2mfs.tfm", vector = "mtpro2-mfa", skewchar=0x7F }, { name = "mt2bmfs.tfm", vector = "mtpro2-bmfa", skewchar=0x7F }, { name = "mt2bbis.tfm", vector = "mtpro2-bbi", skewchar=0x7F }, }, ["mtpro10a-regular"] = { { name = "file:texgyretermes-regular.otf", features = "virtualmath", main = true }, { name = "mt2mit.tfm", vector = "mtpro2-mi", skewchar=0x7F }, { name = "mt2syt.tfm", vector = "mtpro2-sy", skewchar=0x30, parameters = true }, { name = "mt2mbt.tfm", vector = "mtpro2-mb", skewchar=0x7F }, { name = "mt2syat.tfm", vector = "mtpro2-sya", skewchar=0x7F }, { name = "mt2bbt.tfm", vector = "mtpro2-bb", skewchar=0x7F }, { name = "mt2mst.tfm", vector = "mtpro2-mca", skewchar=0x7F }, { name = "mt2bmst.tfm", vector = "mtpro2-bmca", skewchar=0x7F }, { name = "mt2mft.tfm", vector = "mtpro2-mfa", skewchar=0x7F }, { name = "mt2bmft.tfm", vector = "mtpro2-bmfa", skewchar=0x7F }, { name = "mt2bbit.tfm", vector = "mtpro2-bbi", skewchar=0x7F }, }, =================================================================== I guess the suffixes "f" "s" and "t" may correspond to "five" "seven" and "ten", but that's not important. I could use one of them as the virtual font in the typescript: =================================================================== \definefontsynonym [\s!MathRoman] [MTPro10a-Regular@mtpro10a-regular] =================================================================== The output pdf used the 10-size font as expected. I stole some codes from lm.lfg and added the following code: =================================================================== designsizes = { ["MathTimeProA-Regular"] = { ["4pt"] = "MTPro06a-Regular@mtpro06a-regular", ["5pt"] = "MTPro06a-Regular@mtpro06a-regular", ["6pt"] = "MTPro06a-Regular@mtpro06a-regular", ["7pt"] = "MTPro08a-Regular@mtpro08a-regular", ["8pt"] = "MTPro08a-Regular@mtpro08a-regular", ["9pt"] = "MTPro08a-Regular@mtpro08a-regular", ["10pt"] = "MTPro10a-Regular@mtpro10a-regular", ["11pt"] = "MTPro10a-Regular@mtpro10a-regular", ["12pt"] = "MTPro10a-Regular@mtpro10a-regular", default = "MTPro10a-Regular@mtpro10a-regular" }, =================================================================== and modified the typescript: =================================================================== \definefontsynonym [\s!MathRoman] [\v!name:MathTimeProA-Regular] [\s!goodies=math-times-pro-math] =================================================================== It failed as expected: =================================================================== fonts > defining > start stage one: MathRoman mo 1 fonts > defining > specification 'MathRoman mo 1', lookup 'file', name 'MathRoman', sub '', method '', detail '' fonts > defining > stop stage one fonts > defining > start stage two: name:MathTimeProA-Regular (size 393216) fonts > names > font with name 'mathtimeproaregular' cannot be found fonts > names > font database has matching configuration and file hashes fonts > defining > trying (reader sequence driven) type 'otf' for 'MathTimeProA-Regular' with file '' fonts > names > font database has matching configuration and file hashes fonts > defining > trying (reader sequence driven) type 'ttf' for 'MathTimeProA-Regular' with file '' fonts > names > font database has matching configuration and file hashes fonts > defining > trying (reader sequence driven) type 'afm' for 'MathTimeProA-Regular' with file '' fonts > names > font database has matching configuration and file hashes fonts > names > font database has matching configuration and file hashes fonts > defining > loading tfm with name 'MathTimeProA-Regular' fails fonts > defining > trying (reader sequence driven) type 'tfm' for 'MathTimeProA-Regular' with file '' fonts > names > font database has matching configuration and file hashes fonts > defining > loading tfm with name 'MathTimeProA-Regular' fails fonts > defining > trying (reader sequence driven) type 'lua' for 'MathTimeProA-Regular' with file '' fonts > lua loading > using lua reader for 'MathRoman mo 1' fonts > defining > font with asked name 'MathTimeProA-Regular' is not found using lookup 'name' fonts > defining > not loaded and hashed: mathtimeproa-regular @ normal:goodies=math-times-pro-math @ 393216 fonts > defining > unknown font 'MathTimeProA-Regular', loading aborted fonts > defining > unable to define 'MathTimeProA-Regular' as 'math-times-pro-11pt-mm-mr--3' fonts > defining > memory usage after: 45 MB (ctx: 45 MB) fonts > defining > stop stage two =================================================================== I get it. There's no MathTimeProA-Regular file. I've tried the built-in "ebgaramond" typescript which also comes with the "designsizes" field. Interesting, the "ebgaramond-regular" is remapped to "EBGaramond12-Regular" magically: =================================================================== fonts > defining > start stage two: file:ebgaramond-regular (size 720896) fonts > defining > remapping name 'ebgaramond-regular', specification 'auto', size 720896, designsize 'file:EBGaramond12-Regular' =================================================================== Well, what am I missing? How to get the designsize names recognized? What is the right way to make the virtual fonts? Thanks for noticing. Best regards, Zhichu

Mode for footnote?
by Procházka Lukáš Ing. - Pontex s. r. o. 23 Jun '15

Hello, there are many modes for various situations (http://wiki.contextgarden.net/Modes) Is there a mode to signal being inside a footnote? This would be handy for head definition: ---- \definehead[paragraph][subsubsubject] \define\ShBlank{\doifnotmode{*footnote}{\blank}} \setuphead[paragraph][before=\ShBlank] ---- Best regards, Lukas -- Ing.

definereferencestructureprefix for floats

Hi, How does one control the referenceprefix for floats. I want to refer to the figures as only Fig 1, Fig 2, etc, even when they are numbered 1.1, 1.2, etc. The example from strc-ref.mkvi does not work (I get 1.I-A.1 and 1.I-A.2) \defineconversionset[default][Character,number,Romannumerals,Character][number] \defineseparatorset [default][.,.,--][.] \setuphead[subsection][sectionstopper=),sectionsegments=4:4] \setupreferencestructureprefix[default][prefixsegments=2:4] \setupreferencestructureprefix[figure][default][prefixsegments=3:4] \starttext \chapter {One} \section {One} \subsection[sec:test]{Two} See \in[sec:test] and \in[fig:xx] and \in[fig:yy] \placefigure[here][fig:xx]{}{} \placefigure[here][fig:yy]{}{} \stoptext Thanks, Aditya

simplefonts not working with Debian 8.1
by Mica Semrick 22 Jun '15

22 Jun '15

Hello list, I'm having trouble getting system fonts to load with simplefont on Debian 8.1. I'm not exactly sure how to troubleshoot this issue. This worked when Debian Jessie was still 'testing' but now fails on a machine it was working on and on a fresh install. All my fonts are in ~/.fonts and Libre Office Writer can see all the fonts and fc-list shows them as well. In my document, I'm loading fonts like this: \definefontfamily [mainface] [rm] [EB Garamond] \definefontfamily[mainface][sans][Gill Sans] \setupbodyfont[mainface,11pt] \setupbodyfontenvironment[default][em=italic] The log file says: fonts > preloading modern-designsize (math) fonts > typescripts > unknown library 'modern-designsize' fonts > 'fallback modern-designsize mm 11pt' is loaded fonts > preloading modern-designsize (mono) fonts > 'fallback modern-designsize tt 11pt' is loaded fonts > defining > font with asked name 'unknown' is not found using lookup 'file' fonts > defining > unknown font 'unknown', loading aborted fonts > defining > unable to define 'unknown' as 'mainface-11pt-rm-tf-0--0' fonts > defining > font with asked name 'unknown' is not found using lookup 'file' fonts > defining > unknown font 'unknown', loading aborted fonts > defining > unable to define 'unknown' as 'mainface-11pt-mm-mr--3' fonts > defining > font with asked name 'unknown' is not found using lookup 'file' fonts > defining > unknown font 'unknown', loading aborted fonts > defining > unable to define 'unknown' as 'mainface-11pt-mm-mr--2' fonts > defining > font with asked name 'unknown' is not found using lookup 'file' fonts > defining > unknown font 'unknown', loading aborted fonts > defining > unable to define 'unknown' as 'mainface-11pt-mm-mr--1' fonts > defining > font with asked name 'unknown' is not found using lookup 'file' fonts > defining > unknown font 'unknown', loading aborted fonts > defining > unable to define 'unknown' as 'mainface-11pt-mm-mb--3' fonts > defining > font with asked name 'unknown' is not found using lookup 'file' fonts > defining > unknown font 'unknown', loading aborted fonts > defining > unable to define 'unknown' as 'mainface-11pt-mm-mb--2' fonts > defining > font with asked name 'unknown' is not found using lookup 'file' fonts > defining > unknown font 'unknown', loading aborted fonts > defining > unable to define 'unknown' as 'mainface-11pt-mm-mb--1' Any direction I can take to troubleshoot this would be of great help! Thank you for your time. Best, Mica

issue with font sizes

21 Jun '15

Dear list, I have the following sample: \definefontfamily [anothersans] [ss] [DejaVu Sans] \starttext \tfxx smaller text with \anothersans\ss second sans. \stoptext I need to add an alternative ss and tt font. The problem is that when changing the typeface, I get the normal font size. Is this a bug or a feature? How could I avoid it? Many thanks for your help, Pablo -- http://www.ousia.tk
