Dynamic document variables from metadata
by Thangalin 02 Jan '22

02 Jan '22

Happy New Year! How would you implement a mechanism that takes arbitrary XHTML <meta> tags and produces document variables? Consider: <meta name="journal" content="Nature" /> After running XML setups, the following would write "Nature": \documentvariable{journal} The tricky part is doing this without pre-defining them. Here's a short, self-contained example to help demonstrate: \startbuffer[xdoc] <html> <head> <meta content="Milena Marić Einstein" name="author"/> <meta content="Annalen der Physik" name="journal"/> </head> <body> </body> </html>\stopbuffer \startxmlsetups xml:xhtml \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{html|body}{xml:*} \xmlsetsetup{\xmldocument}{head}{xml:meta}\stopxmlsetups \xmlregistersetup{xml:xhtml} \startxmlsetups xml:html % "author" is a special setup, not generalized \xmlfilter{#1}{/head/meta[@name='author']/command(xml:author)} % What goes here to make this dynamic? %\xmlfilter{#1}{/head/meta[@name='journal']/command(xml:journal)} \xmlflush{#1}\stopxmlsetups \startxmlsetups xml:author \setupdocument[author={\xmlatt{#1}{content}}] \setupdocument[metadata:author={\xmlatt{#1}{content}}] \setupinteraction[author={\documentvariable{author}}]\stopxmlsetups % How can this be generalized?%\startxmlsetups xml:journal %\setupdocument[journal={\xmlatt{#1}{content}}]%\stopxmlsetups \startxmlsetups xml:body \startdocument Author: \documentvariable{author} \par Journal: \documentvariable{journal} \stopdocument\stopxmlsetups \xmlprocessbuffer{main}{xdoc}{} Thank you!

Dangerous bends symbol in manfnt.afm accidentally chopped by LMTX?
by Benjamin Buchmuller 02 Jan '22

02 Jan '22

Hi list, using this example from the wiki, the dbend symbol appears cropped on the left side on my machine (ConTeXt ver: 2021.12.10 11:41 LMTX fmt: 2021.12.14), but not on the ConTeXt live server? Any possible reasons? \definefontsynonym [bends] [file:manfnt.afm] \startsymbolset [Dangerous Bends] \definesymbol [dbend] [\resolvedglyphdirect{bends}{n:char_7e}] \definesymbol [lhdbend] [\resolvedglyphdirect{bends}{n:char_7f}] \stopsymbolset \setupsymbolset [Dangerous Bends] \starttext \symbol{dbend}\quad \symbol{lhdbend} \stoptext Thanks Benjamin

aligning Malayalam horizontally across column
by Ajith R 02 Jan '22

02 Jan '22

Hi, I am trying to prepare a moderate sized document in Malayalam using Context. Overall I have been successful. However, there are a few rough edges for which I need help. This is the second problem I face. I have some 300 group of short sentences placed in five columns using \startcolumns[n=5] \input aCharTable.tex \stopcolumns The aCharTex generated by a shell script contains the 300 plus commands with the structure \tfa{ \bold{variable} \par (12 - 0.13) } \blank The problems are that - a) the group, with the two short paras get separated into different columns and sometimes pages. How can I prevent that? In other words, how do I tell Context that this should be treated as cohesive unit? b) The horizontal space doesn't align across columns. This probably is because the different conjuncts in each of these lines have different heights. How can I ask Context to treat each of these cohesive units as having the same height? Thanks, ajith

Asking context to switch to a different font for a single character in many places
by Ajith R 02 Jan '22

02 Jan '22

Hi, I am trying to prepare a moderate sized document in Malayalam using Context. Overall I have been successful. However, there are a few rough edges for which I need help. This is the fifth problem I face. Is it possible to instruct Context to use a font in general, except for a single character? I want to show the space character with open box,␣ U+2423. However, the font doesn't have that character. The open box character shows up in many places within an otherwise Malayalam text. So, switching font is not possible. For the time being, I am using a substitution. However, I would like to know if it is possible. Thanks, ajith

Getting ONE, TWO... for chapters
by jbf 01 Jan '22

01 Jan '22

Am typesetting a book that has 'STUDY ONE', 'STUDY TWO' etc. in place of CHAPTER ONE, etc. I have no difficulty getting 'STUDY' with \setuplabeltext[chapter=STUDY~], and I can achieve 'STUDY One' with the key conversion=Words in \setuphead[chapter]. My question: how do I get ONE instead of One. I tried conversion=WORDS (or WORD), but that is not recognised and the output then becomes STUDY 1, which I don't want. I also tried playing with \definestructureconversionset[myconversion][ ,A,] then adding the numberconversionset=myconversion to \setuphead. There must be a simple way to achieve the desire result, and to be honest I'm wondering why WORD does not work? Any thoughts? Julian

tweaked font options in \definedfontfeature?
by Pablo Rodriguez 01 Jan '22

01 Jan '22

Hans, I wonder whether it would be possible to add the options for tweaked fonts (or at least, xscale and yscale) to \definefontfeature. I think this might ease the use of scaled fonts (at least, in some documents). Many thanks for your awesome work and best wishes for 2022 to you and to all users, Pablo

measure layer/ ruler
by Youssef Cherem 01 Jan '22

01 Jan '22

Dear list users, How can one go about implementing a ruler around the page/text area (such as a background) like the one provided by the latex package fgruler? https://www.ctan.org/tex-archive/macros/latex/contrib/fgruler or koma script's \layercontentsmeasure?
