Wie nutze ich SageTeX?
Hat jmd. Erfahrung mit `Sage` und `sagetex.sty`?
Muss ich erstmal `Sage` und `sagetex.sty` installieren?
`texdco sagetex` liefert mir:
# This is to allow the use of sagetex package
# (www.ctan.org/tex-archive/macros/latex/contrib/sagetex)
# with latexmk. Sagetex outputs a file with the extension .sage.
# This file is to be processed by sage software (sagemath.org)
# to make a file with extension .sout. This file is then read in by
# sagetex during a later run of (pdf)latex.
#
# This can be done by normal custom dependency. However the .sage
# contains unimportant information about line numbers for error
# reporting. It is useful not to rerun sage if this is the only
# information that has changed in the .sage file. So the
# hash_calc_ignore_pattern variable is used to configure latexmk to
# ignore this lines when computing whether the .sage file has
# changed.
add_cus_dep( 'sage', 'sout', 0, 'makesout' );
$hash_calc_ignore_pattern{'sage'} = '^( _st_.goboom|print .SageT)';
sub makesout {
system( "sage \"$_[0].sage\"" );
}
