Re: [NTG-context] follow up

2019-04-02 Thread Christoph Reller

My two cents:

I don't believe that it is the CIDSet. Both fun.pdf and fun1.pdf have no
CIDSet (which is good).
The (relevant) differences between the two PDFs are:
- Different ToUnicode
- Different embedded font stream
- Minor differences in the font descriptor
It could be the ToUnicode: If preview is not able to parse the last entry
in the ToUnicode table then it may also drop this glyph in its display,
although ToUnicode is only relevant for text extraction.
It could be the font stream: In the CFF font file there is a CharSet table
that maps character-IDs to glyph-IDs. If preview cannot read the last entry
in this table (or the last glyph, glyph nr. 10) then it might drop it.
By bet is on the ToUnicode, because, usually, if viewers fail to read a
font file then they drop the entire font file and not single glyphs.

Anyway, both PDFs seem to be valid. But I wonder if the differences in the
font descriptor are legitimate (especially StemV):
Object 9 <-> 7: Different entry Ascent integer value: 1127 <-> 806 in font
descriptor dictionary.
Object 9 <-> 7: Different entry Descent integer value: -280 <-> -194 in
font descriptor dictionary.
Object 9 <-> 7: Different entry StemV integer value: 91 <-> 0 in font
descriptor dictionary.

Cheers,
Christoph

I've modified that block this way:

\newconditional\IndexState
%\define[1]\IndexInternalCommand
\unexpanded\def\IndexInternalCommand#1%
  
{\doifelse{#1}{Dolsko}{\global\settrue\IndexState}{\global\setfalse\IndexState}#1}

%\define[1]\IndexCommand
\unexpanded\def\IndexCommand#1%
  {\setfalse\IndexState
   \setbox\scratchbox\hbox{#1}%
   \ifconditional\IndexState
 \column
   \fi
   \box\nextbox}


Is it what you propose? If so, I am still getting the same error.

Re: [NTG-context] lmtx doesn't search texmf-local

My guess: drop the '/opt/context-lmtx/bin' from your PATH.

That works, thank you. Then install.sh has to be adjusted because it
told me to

export
PATH=/opt/context-lmtx/tex/texmf-linux-64/bin:/opt/context-lmtx/bin:/opt/context-lmtx/tex/texmf-linux-64/bin:...

The install.sh needs to have the /opt/context-lmtx/bin in the path
because the install script (might) need the latest binary to work. The
directory structure is almost similar to context standalone. So, I
simply created a simple setuptex file to ease munging of paths.
nothing fundamental has changed in that department (nor will change
drastically unless there is a good reason for it) .. if things don't
work as expected i'll fix it of course

let me stress that, although there are changes (or pending ones) onder
the hood, most components of context will just stay as they are (why
reinvent wheels that turn smoothly)

for instance, font related code is also supposed to work with plain
which in turn means work with luatex ... the same is true for file
handling, process management etc ...

lmtx is supposed to be a drop in that context knows how to deal with,
but with a whole lot of benefits (like running a bit better on Alan's
refrigerator ... in fact, my thermostat/heating system really does run
on luatex as does other domotica stuff)

(believe it or not but i occasionally do test lmtx in a small setup
because computers don't get faster, virtualization has smaller setups,
energy consumption matters, etc. ... hobyism of course)

one can alway swonder if we keep some ideas in our sleeves .. after all,
there need to be progress occasionally ...
