[NTG-context] Latest beta stops loading some ttc fonts

2014-09-25 Thread Hongwen Qiu

The following minimal example used to work fine:
\starttypescript [serif] [zhfonts]
  \definefontsynonym [Serif] [name:nsimsun]
\stoptypescript

\starttypescript [zhfonts]
  \definetypeface [zhfonts] [rm] [serif] [zhfonts]
\stoptypescript

\usetypescript [zhfonts]
\setupbodyfont [zhfonts, rm, 11pt]

\starttext

测试

\stoptext

but it's no longer the case.

The font used here is 'simsun.ttc' which ships with Chinese edition 
Windows systems by default.
When I require name:nsimsun as above, the TTFAddLangStr() function in 
the luatex code base will have the following information:

fontname lang
NSimSun   0
NSimSun  1033
新宋体   2052
That is when lang equals 0 or 1033, the fontname will be NSimSun, but 
when lang equals 2052, the fontname will be 新宋体, the Chinese words 
for NSimSun.
Although the ValidatePostScriptFontName() complains about the Chinese 
name of this font, and set 'bad_ps_fontname' to true, luatex itself 
don't stop the font fromgetting the right fontname NSimSun, since it 
chooses ASCII names when there're multiple fontnames.


But actions[check metadata](font-otf.lua, 1812),sets the 
metadata.fontname from the correct NSimSun to bad-fontname-simsun, 
and this change causes ff_get_ttc_index() to always return -1 as the 
index, which caused ConTeXt to complain about the following error 
message before bail out:


(bad-fontname-simsun:-1)Invalid TTC index number

mtx-context | fatal error: return code: 1

So, maybe font-otf.lua may need not change metadata.fontname and 
metadata.fullname if these two names are not nil?

is it context or the binary?
Don't know which one changed that caused the above example to fail. I 
havn't used nsimsun for months, and indeed the above code used to run 
properly. Just heard from someone that it works in the current but not 
in the beta.


In my opinion, it's much easier to change the context code to fix this 
problem (about 2 line lua code), but maybe tweaking with the luatex code 
is the way that should be done.


I don't know anything about font format. In the luatex code, a comment 
said that PLRM only support ASCII fontnames. I suppose PLRM is short for 
PostScript Language Reference. I have a quick glance of the 3rd edition 
of PLRM, and only find that fontname have this explanation: (Optional) 
The name of the font. This entry is for information only; it is not
used by the PostScript interpreter. Ordinarily, it is the same as the 
key passed

to definefont , but it need not be.
I noticed that font can have multiple fotnames, each for a lang, just as 
I posted in the previous message that there're 3 fontnames for index 1 
of simsun.ttc. And many other Unicode fonts have non ASCII font names 
for lang other than 0 too. Just enable the warning message when loading 
font, and I noticed a lot of arabic font in the Linux box have Arabic 
font names. So I don't think that context (or luatex) should refuse to 
work when font have non-ASCII fontnames.


Currently there're other font related bugs that I'd wish getting fixed too.
I'm currently trying to find out why typesetting with sourcehansanscn 
will cause some glyphs to disapper.
e.g. the following code should typeset two glyphs 理 and 论. But the 
理 just get deleted from the output.

\starttypescript [serif] [zhfonts]
   \definefontsynonym [Serif] [name:sourcehansanscn]
\stoptypescript

\starttypescript [zhfonts]
   \definetypeface [zhfonts] [rm] [serif] [zhfonts]
\stoptypescript

\usetypescript [zhfonts]
\setupbodyfont [zhfonts, rm, 11pt]

\starttext

理论

\stoptext
FYI. this font can display 理, when I use libreOffice. I have no clue 
how to debug this problem. So some advice about debugging this kind of 
problem is helpful if you're busy to debug the problem. I'd glad to find 
out the reason why it won't work myself.


By the way, I belived that something like \definefontsynonym [Serif] 
[sourcehansanscn] used to load sourcehansanscn correctly but you must 
prefix it with name: now, otherwise it won't load any font.

Usually, luatex get updated regularly along with ConTeXt updating. If 
for some reason, you want to use the latest luatex binary, you need to 
compile it from source code yourself. If you have difficultly compile 
binary from source, you can ask others to compile for you, or just wait 
for the binary to eventually come into the ConTeXt repo.

You must mean pdftops, since pstopdf cannot convert pdf files into eps

I tried pdftops, the result quality is high, but since my desire is to 
provide eps figures to others that have to insert high quality figures 
into Microsoft Word, the pdftops converted eps files cannot insert into 
Microsoft Word. Fortunately, I have found out that pstopdf uses 
ghostscript/Inkscape to do the real job, and I use ghostscript directly 
to convert pdf into eps, the quality is high enough with the -dNOCACHE 
option (I had tried inkscape before my last posting a few weeks ago, and 
the resulting quality is not high enough when I'm using Fedora 16. But 
it seems that inkscape in Fedora 17 produces better quality now, though 
ghostscript is better), and it can be recognized by Microsoft Word.


Thanks for the information.

It seems that if I copied all of the module files under the current

And of course mtxrun --locate t-vim.tex gives the correct location just
as indicated by my previously attached log file.

And there's only one environment variable corresponding to TeX settings:
$ env |grep -i TEX

Actually not only the modules under tex/texmf-modules not work on the
Remote, but also modules under tex/texmf-local don't work either.

 The vim module usually gives a message
 
 loadingVim syntax highlighting
 
 (or some variation of it...I have changed the default message
 recently), 
 but that message is missing in your log.
 
 My guess is that the t-vim module that you have is somehow corrupted,
 and 
 therefore, \definevimtyping command is undefined. 
This couldn't be the problem (anyhow, I attached the 15 lines of
t-vim.tex above), since I have said in my previous messages that if I
copied the neccessary files from the tex/texmf-modules to the current
directory it works just fine, and the problem are not only relates to
t-vim module, all of the modules under tex/texmf-modules and
tex/texmf-local just does not work.

[NTG-context] Strange problem related to \usemodule

2011-10-09 Thread Hongwen Qiu
Hi,

I have access to three machines both running GNU/Linux x86-64, I call
them Laptop, Desktop and Remote respectively here on.

The Laptop has full access to the internet, so I always install and
upgrade my ConTeXt Standalone on it when I'm home.

At workplace, I can surfer the internet with the Desktop while the
RSYNC port is blocked.

I only can access the Remote through ssh from the Desktop without
root privilege and can not access the internet.

So, I always copied the ConTeXt standalone from my Laptop onto my
Desktop, and from my Desktop onto Remote if necessary. Then, I'll
delete the cache before I set the PATH to the appropriate location and
run context --make and mtxrun --generate.

So the ConTeXt standalones are almost identical on both my Desktop and
Remote. And the following minimal example just works fine on my
Desktop but failed on the Remote,
=== Minimal Example 
\usemodule[vim]

\definevimtyping[RUBY][syntax=ruby]

\starttext

\startRUBY
puts Hello
\stopRUBY

\stoptext
=
Actually, on Remote, whatever module I use, it will prompt the
Undefined Control Sequence error regarding the first command I used from
that module with the module loaded correctly. Attached is the error log
accompany the above minimal example.

So, what can be the problem with my Remote.

TIA. for any help.

At the moment I've used \setupcaption[picture][way=bytext] to sort out

\setupcaption[picture][way=bytext,label=Picture] does the trick

I know about many possibilities of \setuplist options but can't find

Use \placetableofcontents instead of \completetableofcontents and 
generate the title with your customized title command.

[NTG-context] \startalign[n=3] don't work properly in MKIV

Hi, the following minimal example works fine in MKII, but the third
columns are not aligned in MKIV

\starttext

\startformula\startalign[n=3]
\NC X \NC = 1 + 2 \NC = 3 \NR
\NC Y \NC = 1 + 2 + 3 \NC = 6 \NR
\NC Z \NC = 1 + 2 + 3 + 4 \NC = 10 \NR
\stopalign\stopformula

Is this a bug or the interface has changed in MKIV?

Can't you construct four outlines instead of three, so that you can 
construct two paths for filling. Hope you understand what I mean.

As a workaround I fill out the bigger one with color black and the smaller one

You can fill out the bigger one, than clips the smaller one.
And alternately, you can construct the path of the difference out of the 
two circles, and fill the constructed path.

[NTG-context] problem with tabulate header and footer

2010-09-20 Thread Hongwen Qiu
 \setuptabulate[footer=repeat] has no effect, so is this a bug or if
something has been changed?

And \setuptabulate[header=repeat] can only repeat a single row(see the
minimal example below). So is this a bug or is it never been implemented
or thought like this?

TIA for any help or feedback.

Minimal example:

\starttext

\setuptabulate[header=repeat, footers=repeat]

\starttabulatehead
\HL
\NC A \NC B \NC C \NC \NR
\NC D \NC E \NC F \NC \NR
\HL
\stoptabulatehead

\starttabulatetail
\HL
\stoptabulatetail

\startluacode
context.starttabulate{|c|c|c|}
for i=1,200 do
context.NC() context(G)
context.NC() context(H)
context.NC() context(I)
context.NC() context.NR()
end
context.stoptabulate()
\stopluacode

\stoptext

The example and its output are attached.

Re: [NTG-context] Clipping of text (or something equivalent)

2010-06-07 Thread Hongwen Qiu

? 2010?06?07? 22:47, Erik Margraf ??:

Hi all,
I'd like to achieve in context something like I did in
the attachment (context.pdf). My idea was (and
that's the way how I did this in Inkscape):

   - Create Text
   - Double the text
   - Clip one for the upper half, clip the other for the lower half
Actually, you only have to clip one, either the upper half or the lower 
half, since the latter elements added onto the canvas will mask the 
former elements.

   - Connect the two halves.

My (probably naive) approach to clipping text in context was:

-
\starttext
\startuniqueMPgraphic{context}
  draw btex \bf Context etex xyscaled (4.0, 4.0) withcolor .8white ;
  clip currentpicture to unitsquare;

take something like:
clip currentpicture to unitsquare scaled 8cm;
and you'll know what's the problem.

\stopuniqueMPgraphic
\null\dontcomplain
\uniqueMPgraphic{context}
-

(Without the clip - line, the string Context is displayed. With
clipping, nothing is displayed.)

Any hint in the right direction towards clipping or maybe a better
way to achieve this is appreciated.

Thanks

Erik

Re: [NTG-context] 3. Re: \MPpos, pxy, initialize_box(), oh my! (Hongwen Qiu)

2010-06-05 Thread Hongwen Qiu

? 2010?06?05? 10:56, Adam Fuller ??:
my initial post had a mistake:  i meant to refer to the /Metafun/ 
manual, not the Metapost manual.  that probably didn't help.

Actually, I know that you mean the /Metafun/ manual.
i guess what i should have said is, i know that pxy can give me the 
bounding /box/ (the rectangle with the maximum horizontal and vertical 
extents of its contents, be they set in horizontal or vertical mode), 
but can it give me the subset of that, the bounding /path/, if you 
will, when the contents are text which flows over several lines.  the 
bounding /path/ may not be rectangular, although it will be something 
like the union of the bounding boxes of the text's individual lines.

So now, I understand what mean.
i think if you look at the correct reference, the difference of the 
effects is clear.  i think the challenge is that you don't know where 
the line breaks will occur until you typeset it.   --adam 

And the source code from the manual may help you:

\setupMPvariables[mpos:box][linecolor=darkred]
\setupMPvariables[mpos:par][linecolor=darkred]

\startpositionoverlay{backgraphics}
  \setMPpositiongraphic{A-3}{mpos:box}{self=A-3}
  \setMPpositiongraphic{A-4}{mpos:box}{self=A-4}
  \setMPpositiongraphic{b:A-5}{mpos:par}{self=A-5}
  \setMPpositiongraphic{b:A-6}{mpos:par}{self=A-6}
\stoppositionoverlay

\fpos {A-5} Because the text must be laid on top of
the graphic, the graphic must precede the first word in the
typeset stream or it must be positioned on a separate layer.
In the latter case it can be calculated directly after the
paragraph is typeset, but in the former case a second pass
is needed. \tpos {A-5}

Given the above code, I think you can get some information about the 
horizontal and vertical pos of texts from \fpos and \tpos. And the 
mpos:par is defined in anch-pgr.mkii and anch-pgr.mkiv. But I haven't 
dig into the code which implement mpos:par. Hope you can find useful 
information there.


And hope the following message I just searched out will help you too:

initialize_box sets `pxy' to \hpos's contents bounding box. what if 
you want pxy to be not strictly a rectangle, but the path that 
encloses text, etc., which is just part of flowing text in a paragraph
If I'm not misunderstanding some concepts, bounding boxes are sure to be 
rectangles. But why you need `pxy` to not be rectangle. Since you can 
get the center and all the four-corner cordinates (and so it's easy to 
get the diameter if you want to use it as circles or something like that 
latter) of the bounding box, you can construct all kinds of path shapes 
if needed.

There's an example at

[NTG-context] Running standalone metapost file omits spaces between btex and etex

2010-05-07 Thread Hongwen Qiu
I found that the following example

\starttext

\startuseMPgraphic{test}
draw btex some text with space etex;
\stopuseMPgraphic
\useMPgraphic{test}

\stoptext

can generate the text between btex and etex correct no matter I use
MKII or MKIV.

But, when I running the following example

beginfig(0);
draw btex some text with space etex;
endfig;
end

with the command line:

$ mpost --mem=metafun test.mp

or

$ texexec --mptex test.mp

It dose generate output. But the output omits all the spaces between
btex and etex, with the resulting string to be sometextwithspace.

So, the question is how to get the correct results when running
standalong metapost file with btex-etex strings.

Thanks.

module, while loading the adobesongstd font and some other Chinese 
fonts. So, the problem maybe something's wrong with the simplefonts 
module. The following is a simple example.


\usemodule[simplefonts]

\setcjkmainfont[adobesongstd]

\starttext

\starttyping
--
\stoptyping

\type{--}

\stoptext

And if I use \setmainfont[some Western Fonts] instead of the 
\setcjkmainfont line, the problem still exists.

Add '\setmonofont[Latin Modern Mono][features=none]' to your file.

Yes, this works. Tanks.

[NTG-context] standardmakeup environment didn't work in MKIV

2010-03-31 Thread Hongwen Qiu
Hi all,
standardmakeup didn't work in MKIV.
When I used this environment, It complains:

error: Invalid field id writable for node type glue_spec (0)
.
\stopmakeup ...ter \c!color }{\stopcolor }\egroup
\flushmarks \doflushmakeup...
l.3 \stopstandardmakeup

So, is this something deprecated or just some unexpected things
happened? And what I supposed to do if I want to get the same results?

This means your luatex is older than it should be for the current
mkiv beta. The 'writable' glue_spec field was introduced in
luatex 0.52.
   
It works now. Thanks. I thought that the luatex shipped with the latest 
ConTeXt was the latest beta. Now I know that it is just the stable one.
