[NTG-context] processing xml with lua
Hi all,
one of my favorite topics… Here is a minimal example which shows something that
I don't understand: when I process the subsection with the lua code, I want to
get the value of the current section's label attribute in xml.attribute(r,
../../section, label, X). So i was expecting that lua would go up
(../../) and fetch the current section's label. But if you run the example, you
see that it actually always gets the first section's label (value is always 1).
How can I get the current section's label with a lua function?
THanks and all best
Thomas

you go up to the parent of sections which to far up, try:
section = xml.attribute(r, .., label, X)
or
section = xml.filter(r, ../attribute(label))

me?
When you use a font in MkIV you have to specify which features of the
font should be enabled/disabled, to do this you define first a list
for them with the \definefontfeature command, e.g.
\definefontfeature[myfeatures][liga=yes,onum=yes,___]
For the main fonts in the document which are loaded with
\setupbodyfont these settings are applied in the typescripts, e.g.
\defintfontsynonym[Serif][MyRegularFont][features=myfeatures]
but when you load a single font with \definefont you apply
the list as argument to the font name after the asterisk.
When you want only a bigger version of the serif or sans version of
your document you can say \definefont[SansBold at 70bp] without
applying the list of features because the are already set in the
typescripts.
Wolfgang
Is there a document or documents whare all this knowledge is
dispensed?
I hesitate to trouble you with a string of questions,
one by one. Right now the two critical files are:
\input formatting.tex
---
\usemodule [simplefonts]
\definefont [titlefont][MyriadPro-Bold*default at 70bp]
\definefont [subtitle][MyriadPro-Bold*default at 25bp]
\definefont [gauthor][MinionPro-Regular*default at 25bp]
---
followed by:
\input title.tex
-
\startstandardmakeup[align=middle]
\startstyle[titlefont]
Classic COBOL
\stopstyle
\vfil
\style[subtitle]{A Concise Guide}
\vfil
\null
\vfil
\style[gauthor]{John Culleton}
\vfil
\style[subtitle]{Wexford Press}
\stopstandardmakeup
And the error messages indicate that MKIV cannot find those otf
files but they exist in /usr/share/fonts/OTF. The run completes
but other fonts and sizes are used for the title page.
