Problem with encoding, XML and writetolist...

Problem with encoding, XML and writetolist...

[Martin Kolařík]

Hi all,

I have problem with chars encoding now; I have updated ConTeXt sometimes in
January; before the time I was using old (year) version. In this
prehistorical version the problem was not present.

What is the stuff? The following code generates content with titles without
spaces -- accented characters are replaced with \char XXX variant, so during
reading TUI line TeX gobbles a space after XXX as a part of <number> syntax
rule.

Can I do something? With encoding? With XML?

Thank you very much, have a nice day, Martin

Code:

\defineXMLenvironment
  [chapter]
  {\defineXMLsave[title]}
  {\expanded
     {\chapter\XMLflush{title}}}

\starttext

\startbuffer

<chapter>
  <title>Ahojá hojč kuna</title>
</chapter>

\stopbuffer

\processXMLbuffer

\completecontent[criterium=all]

\stoptext

can you send me a zip with the test file so that the 8 bit chars are ok?

Re: Problem with encoding, XML and writetolist...

[Martin Kolařík]

Aha, here maybe will be the solution :-)

I'am using standalone Win32 distribution from Pragma and I'm running texexec with --translate=cp1252cs. Typescripts use il2, which corresponds to fonts, of course. If I run the code without XML (if I transcribe XML to \chapter etc.) I get toc entry correctly too.

Where should I look for more? What is natural.ctx?

Thank you,

Martin

this is a one-to-one translation vector, and the one standard used by context; forget about all those other mappings, they can be done using regimes; you can use an il2 input regime, and any (resonable) font encoding,

Re: Problem with encoding, XML and writetolist...

[Martin Kolařík]

I was confused with typo (ctx=tcx :-) but I still did not succeed. I now installed last cont-tfm, I tried 8bit.tex (from the example) and nothing :-(

I am using now directly "texexec 8bit.tex", which leads to natural.tcx and english interface, without anything more. I tried to change regimes in 8bit.tex too, and the characters were changing. So regimes are OK, result not.

Texexec still reports:

chapter         : 1 ÄluŁou\char 163 c\char 237  kon\char 165  \char 250 p\char 237

which is not good. And I am not able, when not using cp1250.tcx, recode win1250 (default for win) to latin2. There I am able to write regime for myself (cp1250), but I suppose, that whenever characters will not expand to \char XXX form, cp1250.tcx still will be working and usable.

Cannot be set somewhere something badly in my local context configuration?

Thank you,

Martin

Hans, I would guess that more than 50% of Slavic Windows users (ie.
Slovenian, Croatian, Chech, Slovak, ...) use the cp1250 encoding
(including me). Would it be possible to add at least this file
http://pub.mojca.org/tex/enco/contextbase/regi-cp1250.tex to the
default ConTeXt distribution? (with "synonyms" windows-1250 and
cp1250).

This has probably nothing to do with the problem described here, but I
believe that many users would appreciate to have that "encoding"
(called regime in ConTeXt) available.

\enableregime[windows] is cp1252 (Western European Windows) not cp1250
(Central European Windows), --translate=cp1250cs is cp1250 (supposing
that you don't use \enableregime[windows], but the default one):
everything will be mixed up if you use both simultaneously.

If you download the file mentioned above (place it into the current
directory or somewhere in the TeX tree and refresh the filename
database) or if Hans adds it to the distribution, you can use
\input regi-cp1250
\enableregime[cp1250]

This probably won't solve your problem with missing spaces (didn't try
it), but you'll have the proper encoding.

specifically for you:

\mainlanguage[cz]
\enableregime[windows] % or \enableregime[latin2] for il2

is enough for Latin Modern and Czech.

Re: Problem with encoding, XML and writetolist...

[Martin Kolařík]

Thanks Vit, your solution perfectly works (I tried it :-); but not for me -- in my case (and in another mine cases too) I use XML code, which remaps some pieces to \chapter. And during the expansion accented characters are replaced with "\char xxx", this is written to tui/tuo file and read back without spaces -- the spaces are gobbled by TeX's number syntactic rule...

But, Hans, when I added \mainlanguage[cz] before \enableregime[windows] in 8bit.tex and run texexec with --translate=cp1250cs, I got:

! Illegal parameter number in definition of \@@expanded.

Re: Problem with encoding, XML and writetolist...

[Martin Kolařík]

Hi Hans,

I've analyzed the situation using different combinations of regimes and encodings, including switching off handling (\donothandleactivecharacter) and it seems to me, that every text with chars > 127, which is fully expanded (as in 8bit.tex), must cause difficulties, because TOC entry read back from TUO is scanned independently and thus spaces are gobbled.

Now I have solved it using not-stable solution -- I am using triple sequence of \expandafter to expand \XMLflush after \chapter instead \expanded. The solution is not stable as it is ConTeXt implementation dependent.

On the other side, now I do not know, how to partially expand code \chaper{\XMLflush{XMLTag}} to obtain sequence of simple unexpanded chars. Simple \expandafter is not sufficient, more \expandafters is dirty trick and full expansion (\expanded) leads to TOC entry problem. In TeX source this cannot occur (or can occur in strange situations :-), in XML source this is almost rule.

Maybe it would be useful to have in XML engine macro, which expands XMLdata exactly to get read (original) content (like mine triple \expandafter). Maybe such macro already exists and I am a real fool :-)

Thank you for help, have a nice day,

Martin

Re: Problem with encoding, XML and writetolist...

[Martin Kolařík]

Hi Hans,

I've analyzed the situation using different combinations of regimes and encodings, including switching off handling (\donothandleactivecharacter) and it seems to me, that every text with chars > 127, which is fully expanded (as in 8bit.tex), must cause difficulties, because TOC entry read back from TUO is scanned independently and thus spaces are gobbled.

Now I have solved it using not-stable solution -- I am using triple sequence of \expandafter to expand \XMLflush after \chapter instead \expanded. The solution is not stable as it is ConTeXt implementation dependent.

On the other side, now I do not know, how to partially expand code \chaper{\XMLflush{XMLTag}} to obtain sequence of simple unexpanded chars. Simple \expandafter is not sufficient, more \expandafters is dirty trick and full expansion (\expanded) leads to TOC entry problem. In TeX source this cannot occur (or can occur in strange situations :-), in XML source this is almost rule.

Maybe it would be useful to have in XML engine macro, which expands XMLdata exactly to get read (original) content (like mine triple \expandafter). Maybe such macro already exists and I am a real fool :-)

Thank you for help, have a nice day,

Martin

some commands indeed have keys like: 

expansion=no|yes|utf|xml|command 

and alike 

the problem is that when one does something \expanded{...} in a style, it bypasses this mechanism 

can you make me a (as small as possible) example of a doc? i can then test it here with my version

Hi Martin,

we have discussed this problem a year ago. In that time I solve it just 
writing '{}' in each title where was needed, like

   \chapter{Dobré{} ráno}

Now I have cooked an automatic solution. It is not optimal (effective) 
but working. The only needs is to redefine

   \def\numcharacter#1{\char#1{}}
   \let\dochar\numcharacter

and to load appropriate encoding file once more. Since it is banned a 
new macro \reuseencoding was introduce:

For Hans:
It would be nice if this feature was enabled in a standard distro. 
Perhaps you will find some more optimal solution...

I got a brainwave ... 

\enableregime[latin2]

\starttext

\def\numcharacter#1{\rawcharacter{#1}}%
\let\dochar\numcharacter

\writetolist[chapter]{1}{Dobré ráno}

\expanded{\writetolist[chapter]{2}{Dobré odpoledne}}

\placelist[chapter][criterium=text]

test

\typefile{test.tuo}

\stoptext

this can be sped up (a bit) with 

% \dostepwiserecurse{0}{255}{1}
%   {\setevalue{rchr:\recurselevel}{\rawcharacter\recurselevel}}

% \def\rawcharacter#1{\getvalue{rchr:#1}}

this means that all chars are round tripped to themselves in output files! 

raw characters are not active and they are therefore equivalent to \char  

it's enough then to put 

\def\numcharacter#1{\rawcharacter{#1}}%
\let\dochar\numcharacter

into cont-new.tex 

(i will discuss this in more detail with taco later)

So there is no need to have only 7-bit chars in tui/tuo etc.? All right, 
I think this will be better also for sorting. Sounds promissing.

Encoding has "nothing" to do with it. I don't really understand the
\[un]expanded commands in TeX, but this part could theoretically be
problematic:
 {\expanded
    {\section{\XMLflush{title}}}}

Consider the following (encoding-independent) minimal example, just in
case that this can help any of the gurus to understand the problem:

\defineXMLenvironment
 [chapter]
 {\defineXMLsave[title]}
 {\expanded
    {\section{\XMLflush{title}}}}

\starttext
\startbuffer
<chapter>
 <title>$a+b$</title>
</chapter>
\stopbuffer

\processXMLbuffer
\placecontent[criterium=all]
\stoptext

The entry in TOC is different from the title (one is in math mode and
the other one writen with dollars - literally).

Re: Problem with encoding, XML and writetolist...

[Martin Kolařík]

OK, expansion is not encoding, but expansion in this place here is not a
problem (I suppose). The section head is good, but the TOC entry not. So the
inner expansion (or conversion or detokenization or so) around writetolist
is probably affected by something, what now I cannot handle.

And what is strange -- Hans did not reproduce the behaviour (as he wrote),
so I am asking a trying to find the problem on my side (or lucky thougth
:-)...

Thank for your ideas and help,

Martin

Re: Problem with encoding, XML and writetolist...

[Martin Kolařík]

[-- Attachment #1: Type: text/plain, Size: 4301 bytes --]

Hi Hans and Vit,

I've attached pdf and tex made with "texexec 8bit.tex" using the last beta (with cp1250 regime). The version chapterB is what I am using now, chapterA version is straightforward but not functional.

>From this my ideas from last mail came -- when I am expanding \XMLflush exactly and controlled, result is OK (the expansion stops before active characters start to expand.

IMHO, the solution on character level is something different (although it works :-); yes, I did not study Vit's problems from year before. I never had a problems with simple TeX (\chapter{čřžý}), only with XML :-), so for me it would be sufficient solve XML level. Of course, if it is stuff of other level, it cannot be solved in XML.

Thanks, Martin

the {} may break liguature building (and maybe kerning) ... taco knows ...

I got a brainwave ... 

\enableregime[latin2]

\starttext

\def\numcharacter#1{\rawcharacter{#1}}%
\let\dochar\numcharacter

\writetolist[chapter]{1}{Dobré ráno}

\expanded{\writetolist[chapter]{2}{Dobré odpoledne}}

\placelist[chapter][criterium=text]

test

\typefile{test.tuo}

\stoptext

this can be sped up (a bit) with 

% \dostepwiserecurse{0}{255}{1}
%   {\setevalue{rchr:\recurselevel}{\rawcharacter\recurselevel}}

% \def\rawcharacter#1{\getvalue{rchr:#1}}

this means that all chars are round tripped to themselves in output files! 

raw characters are not active and they are therefore equivalent to \char  

it's enough then to put 

\def\numcharacter#1{\rawcharacter{#1}}%
\let\dochar\numcharacter

into cont-new.tex 

(i will discuss this in more detail with taco later)

indeed there is a problem when a regime does not match an font encoding; i'll have a look

Problem with encoding, XML and writetolist...

[Martin Kolařík]

Hi Hans,

I have problem with chars encoding now; I have updated ConTeXt sometimes in
January; before the time I was using old (year) version. In this
prehistorical version the problem was not present.

What is the stuff? The following code generates content with titles without
spaces -- accented characters are replaced with \char XXX variant, so during
reading TUI line TeX gobbles a space after XXX as a part of <number> syntax
rule.

Can I do something? With encoding? With XML?

Thank you very much, have a nice day, Martin

Code:

\defineXMLenvironment
  [chapter]
  {\defineXMLsave[title]}
  {\expanded
     {\chapter\XMLflush{title}}}

\starttext

\startbuffer

<chapter>
  <title>Ahojá hojč kuna</title>
</chapter>

\stopbuffer

\processXMLbuffer

\completecontent[criterium=all]

\stoptext
