Zdravim vsechny,

Byl tu resen problem natahovacich zavorek v LaTeXu. Potrebuji naopak udelat
slozenou zavorku o presne zname vysce. V TeXu jsem si upravil definici podle
TBN, str. 341 takto:

\catcode`\@=11
\def\n@space{\nulldelimiterspace=0pt \m@th}
\def\Biggg#1{{\hbox{$\left#1\vbox to 40pt{}\right.\n@space$}}}
\catcode`\@=9

V normalnim plainovskem textu mi to funguje korektne, staci napsat \Biggg\} a
mam ji tam -- jenze tu svorku potrebuji dostat do METAPOSToveho obrazku a
kdyz napisu toto:

label.bot(btex
\catcode`\@=11
\def\n@space{\nulldelimiterspace=0pt \m@th}
\def\Biggg#1{{\hbox{$\left#1\vbox to 40pt{}\right.\n@space$}}}
\catcode`\@=9
$\Biggg\}$ etex,z101);

nebo toto:

label.bot(btex
...
$\mathclose\Biggg\}$ etex,z102);

tak mi to mpost nebere a krici neco o nedefinovanych ridicich sekvencich.
(error log je úplně na konci) -- jako by se vzpiral tem zavinacum...

Takova vec treba funguje korektne:
label.bot(btex $\mathclose\Bigg\}$ etex,z102);
jenze ta zavorka je pro mne prilis kratka :(

Nebo se da nejak nejak v METAPOSTu zvetsit ta "obycejna" zavorka?

Co jsem zasklil? Co delam spatne? Priznam se, ze METAPOST se teprve nesmele
pokousim dobyvat a mozna jsem prehledl neco elementarniho...

BTW: Resili jste nekdo v METAPOSTu umisteni textu podle krivky?

Dekuji za radu a preji hezky den

Pohoda

Josef

Bohuzel ted nemam cas Vas problem blize prostudovat, pripadne vyzkouset.
Jen bych chtel upozornit na jednu castou chybu:
nastaveni formatu TeXu, ktery je volan Metapostem pro
sazbu napisu. Je vhodne nastavit si takovy format, na ktery je
clovek zvykly. (ja treba mam nastaveny csplain).

Ten mechanismus je mirne systemove zavisly, takze neberte prosim
vse zcela doslova. MetaPost proste nasype vse, co najde ve svem
zdrojovem textu pro sazbu TeXem do pomocneho souboru
mpx__tmp.tex (nebo podobne) a pak jej predhodi ke zpracovani
TeXu. Dalsim samostatnym programem pak z vysledneho .dvi
udela dalsi pomocny soubor, ktery zpracovava do sveho vystupu.

Pro reseni Vaseho problemu je nejlepsi upravit skript, ktery
tohle zarizuje tak, aby na zaver ty pomocne soubory nemazal.
Tak snadno zjistite, co Vam MP do toho pomocneho souboru napsal
a proc se nad tim TeX zlobi.

Asi najpohodlnejsie je na taketo veci pouzit METFUN, co je subor makier
postaveny na METAPOSTe, urceny pre ConTeXt. V manuali metafun-p.pdf zo
strankok www.pragma-ade.nl je v casti 10.4 pojednanie o texte umiestnenom
podla roznych kriviek. Snad by tento posup, po uprave, slo uplatnit aj v
cistom METAPOSTe.

Poblem je, ze se to da cele dovnitr do \shipout\hbox, a to vadi. Proc,
to nevim.
To treba vysvetli nekdo jiny.
Obsah toho pomocneho texovskeho souboru (dole Vam p. Kloc radi, jak si
ho nenechat smazat) je

\shipout\hbox{\smash{\hbox{\hbox{% line 7 D:/TMP/POLACH/pokmp.mp

\catcode`\@=11
\def\n@space{\nulldelimiterspace=0pt \m@th}
\def\Biggg#1{{\hbox{$\left#1\vbox to 40pt{}\right.\n@space$}}}
\catcode`\@=9

$\Biggg\}$}\vrule width1sp}}}
\end{document}

Bez problemu ale funguje toto:

verbatimtex

\catcode`\@=11
\def\n@space{\nulldelimiterspace=0pt \m@th}
\def\Biggg#1{{\hbox{$\left#1\vbox to 40pt{}\right.\n@space$}}}
\catcode`\@=9

etex

beginfig(1);

label.bot(btex
$\Biggg\}$ etex,origin);
endfig;

end

V tom souboru pak je

\catcode`\@=11
\def\n@space{\nulldelimiterspace=0pt \m@th}
\def\Biggg#1{{\hbox{$\left#1\vbox to 40pt{}\right.\n@space$}}}
\catcode`\@=9

%
\shipout\hbox{\smash{\hbox{\hbox{% line 12 D:/TMP/POLACH/pokmp.mp
$\Biggg\}$}\vrule width1sp}}}
\end{document}

a vse je v poradku.

Zajimalo by mne ale, proc davate \catcode`\@=9. Cekal bych \catcode`\@=12.
Na ten problem to ovsem nema vliv.

Zdravi

Nejsem si uplne jist, ale domnivam se, ze \hbox nejprve nacte svuj obsah
(podobne jako makra ctou sve argumenty). \catcode`\@=11 tedy prijde na
radu v okamziku, kdy uz je text rozlozen na tokeny. \def pak definuje
makro \n, ktere musi byt pri kazdem pouziti nasledovano textem @space (to
mate). Na koci rozvoje tohoto makra je \m nasledovane textem @th -- a \m
asi definovane neni.

No jasne, mohlo me napadnout, ze vse mezi btex a etex
se strka do boxu a ze strkat tam definice neni to prave orechove.
Reseni napsal pan Kuben: definice dat samostatne do
verbatimtex a pak je pouzivat v jednotlivych napisech.
