[NTG-context] tagged elements in tables (TABLE, tabulate, xtable)

[Rik Kabel]

List,

I am trying to use tables in an export with tagging to support CSS 
styling for eventual ebook production (with the added hope that 
cross-references and perhaps indexing someday might be supported). I 
have run into an odd limitation. It seems that only tagged element may 
not be present in a table.


The primary use is to manage text in sidebars (first or last column, 
moved by CSS to the correct position, for a two- or three-column one-row 
table).


 * When there are three tagged (or more) elements in the table, the
   table is not present in the resulting html export, nor is much of
   the document following it, and the file is not well-formed.
 * When there are two tagged elements in the table, the resulting html
   export is without part of the document following the table and is
   not well-formed (even though the table appears complete with the tag
   divs).
 * When there is only one tagged element in the table, the resulting
   html export appears to include the complete document but is still
   not well-formed.
 * When there are none, all is well, except that there is nothing to
   which I can associate the needed CSS.
 * In all cases, the pdf output is correct, but the pdf is a throw-away
   when generating html exports.

It looks like tagged elements are not currently supported within tables.

I had thought of putting the table into a tagged element and using 
nth-child selectors to apply CSS to cells by column, but that is finicky 
and it does not offer the flexibility that tagged elements provide.


Can anyone suggest another alternative?

Example follows. As supplied, no tagged elements are generated and all 
is well. Uncomment either the start/stop element lines in the table to 
get one tagged element in the output, or the getbuffer line to get two 
(or all to get three, or...). There are similar problems with tabulate 
and xtables, but only TABLE is shown here.

Yes, I guess that I always confuse [intext] with [text] (which adds joinedup 
and no break). Indeed intext is what I want.

Thank you - it was a silly question.

align=left means raggedleft
align=right means raggedright

This is historical, and remains for compatibility.

use

align=flushleft
align=flushright
align=middle

Not sure whether I understood the question correctly.

[NTG-context] align is reversed inside a table

[David Walther]

Using this table as an example, when I do align=left, the column aligns right,
and when I do align=right, it aligns left.  align=center works as expected.  Am
I doing something wrong or is this a bug?

I am using the version of context distributed with Debian unstable:

mtx-context | ConTeXt Process Management 1.01
mtx-context |
mtx-context | main context file:

[NTG-context] table making ugly column sizes, how to fix?

[David Walther]

Full example at the bottom.

I'm making a table.  So far so good.

Every so often I want to make something like a section header.

Regular table rows are like this:

\bTR\bTC \eTC\bTC NightShift \eTC\bTC Tension Lines 146 - 150 \eTC\eTR

For the section headers, I do this, and they look the way I want:

\bTR\bTC 30. \eTC \bTC[nc=2,align=center,style=] \bf{Foo Bar} \eTC\eTR

But then the regular lines have ugly line breaks and suddenly the column size 
of column 3 is squeezed.  This shouldn't be, we have the whole page to work 
with.

So, when I do my section headers this way, the columns come out sized nicely, 
but the section header isn't styled the way I want it:

\bTR\bTC 30. \eTC \bTC\eTC \bTC[align=center] \bf{Foo Bar} \eTC\eTR

Below is my minimal example you can cut and paste.  How do I do the section
headers without messing up the column sizing?


\setuppagenumbering[alternative=doublesided,location=none,page=no]
\setupfootertexts[\sans{Source: http://mywebsite}]
\setupheadertexts[test column text wrapping]
\setupheadertexts
 [] [Page \userpagenumber\ of \lastuserpagenumber]
 [Page \userpagenumber\ of \lastuserpagenumber] []
\setuppapersize[letter, portrait]
\setuplayout[topspace=0.5in, backspace=1in, height=10in, width=7in,
header=0.5in, footer=0.5in, headerdistance=0in, footerdistance=0in]
\switchtobodyfont[12pt]
\starttext
\setupTABLE[split=repeat]
\setupTABLE[r][each][toffset=3pt, boffset=3pt, loffset=3pt, roffset=3pt]
\setupTABLE[c][each][leftframe=off,rightframe=off,align=right]
\setupTABLE[c][first][frame=off,align=left]
\setupTABLE[c][2][style=\tfx\it,align=left]
\bTABLE
\bTABLEhead
\bTR\bTH Col1 \eTH\bTH Col2 \eTH\bTH Col3 \eTH\eTR
\eTABLEhead
\bTABLEnext
\bTR\bTH Col1 \eTH\bTH Col2 \eTH\bTH Col3 \eTH\eTR
\eTABLEnext
\bTABLEbody
\bTR\bTC \eTC\bTC NightShift \eTC\bTC Tension Lines 146 - 150 \eTC\eTR

% This displays the way I want, but breaks the regular rows.
\bTR\bTC 30. \eTC \bTC[nc=2,align=center,style=] \bf{Foo Bar} \eTC\eTR

% This works with the regular rows, but doesn't look how I want.

[NTG-context] setupitemize (no hanging)

[Alan Braslau]

Silly question:

How do I setup itemize so that there be no hanging indent and the symbol is 
aligned with the left edge of the text, i.e. not in the margin? (margin or 
inmargin or width=-2em puts the symbol in the margin.)

Re: [NTG-context] remapper change in luatex-basics-gen.lua

The remapper is then used in resolvers.findfile.

The change has been imported in latex with the new luaotfload and
now broke the function  "pgf_lookup_and_require" in the pgf
graphdrawing library which in its code uses resolvers.findfile --
probably so that it works also as context library
(http://minimals.contextgarden.net/current/modules/t-tikz/tex/generic/pgf/graphdrawing/tex/pgflibrarygraphdrawing.code.tex)

Due to the mapping of lua to the tex type
resolvers.findfile("layered","lua") no longer finds layered.lua.

Apart from telling the pgf people not to use resolvers.findfile like
this when latex is used, is there anything one could do in the
generic fontloader?
hm, isn't latex using kpse ? in generic this resolver is just for fonts 
(and this one is for lua font files - some demos - with luatex-plain)
