LaTeX macros¶
AUTHORS:
 John H. Palmieri (200903)
The code here sets up LaTeX macro definitions for use in the
documentation. To add a macro, modify the list macros
, near the
end of this file, and then run ‘sage b’. The entries in this list are
used to produce sage_latex_macros
, a list of strings of the form
‘\newcommand…’, and sage_mathjax_macros
, a list of strings
suitable for parsing by MathJax. The LaTeX macros are produced using
the _latex_
method for each Sage object listed in macros
, and
the MathJax macros are produced from the LaTeX macros. The list of
LaTeX macros is used in the file
sage.docs.conf
to add to the preambles of
both the LaTeX file used to build the PDF version of the documentation
and the LaTeX file used to build the HTML version. The list of
MathJax macros is used in the file
sagenb/notebook/tutorial.py
to define MathJax macros for use
in the live documentation (and also in the notebook).
Any macro defined here may be used in docstrings or in the tutorial (or other pieces of documentation). In a docstring, for example, “ZZ” in backquotes (demarking math mode) will appear as “ZZ” in interactive help, but will be typeset as “\Bold{Z}” in the reference manual.
More details on the list macros
: the entries are lists or tuples
of the form [name]
or [name, arguments]
, where name
is a
string and arguments
consists of valid arguments for the Sage
object named name
. For example, ["ZZ"]
and ["GF", 2]
produce the LaTeX macros ‘\newcommand{\ZZ}{\Bold{Z}}’ and
‘\newcommand{\GF}[1]{\Bold{F}_{#1}}’, respectively. (For the
second of these, latex(GF(2))
is called and the string ‘2’ gets
replaced by ‘#1’, so ["GF", 17]
would have worked just as well.
["GF", p]
would have raised an error, though, because p
is not
defined, and ["GF", 4]
would have raised an error, because to
define the field with four elements in Sage, you also need to specify
the name of a generator.)
To see evidence of the results of the code here, run sage docbuild
tutorial latex
(for example), and look at the resulting LaTeX file in
SAGE_DOC/latex/en/tutorial/
. The preamble should
contain ‘newcommand’ lines for each of the entries in macros
.

sage.misc.latex_macros.
convert_latex_macro_to_mathjax
(macro)¶ This converts a LaTeX macro definition (newcommand…) to a MathJax macro definition (MathJax.Macro…).
INPUT:
macro
 LaTeX macro definition
See the web page http://www.mathjax.org/docs/1.1/options/TeX.html for a description of the format for MathJax macros.
EXAMPLES:
sage: from sage.misc.latex_macros import convert_latex_macro_to_mathjax sage: convert_latex_macro_to_mathjax('\\newcommand{\\ZZ}{\\Bold{Z}}') 'ZZ: "\\\\Bold{Z}"' sage: convert_latex_macro_to_mathjax('\\newcommand{\\GF}[1]{\\Bold{F}_{#1}}') 'GF: ["\\\\Bold{F}_{#1}",1]'

sage.misc.latex_macros.
produce_latex_macro
(name, *sample_args)¶ Produce a string defining a LaTeX macro.
INPUT:
name
 name of macro to be defined, also name of corresponding Sage objectsample_args
 (optional) sample arguments for this Sage object
EXAMPLES:
sage: from sage.misc.latex_macros import produce_latex_macro sage: produce_latex_macro('ZZ') '\\newcommand{\\ZZ}{\\Bold{Z}}'
If the Sage object takes arguments, then the LaTeX macro will accept arguments as well. You must pass valid arguments, which will then be converted to #1, #2, etc. in the macro definition. The following allows the use of “GF{p^n}”, for example:
sage: produce_latex_macro('GF', 37) '\\newcommand{\\GF}[1]{\\Bold{F}_{#1}}'
If the Sage object is not in the global name space, describe it like so:
sage: produce_latex_macro('sage.rings.finite_rings.finite_field_constructor.FiniteField', 3) '\\newcommand{\\FiniteField}[1]{\\Bold{F}_{#1}}'

sage.misc.latex_macros.
sage_latex_macros
()¶ Return list of LaTeX macros for Sage. This just runs the function
produce_latex_macro()
on the listmacros
defined in this file, and appendssage_configurable_latex_macros
. To add a new macro for permanent use in Sage, modifymacros
.EXAMPLES:
sage: from sage.misc.latex_macros import sage_latex_macros sage: sage_latex_macros() ['\\newcommand{\\ZZ}{\\Bold{Z}}', '\\newcommand{\\NN}{\\Bold{N}}', ...

sage.misc.latex_macros.
sage_mathjax_macros
()¶ Return list of MathJax macro definitions for Sage as JavaScript. This feeds each item output by
sage_latex_macros()
toconvert_latex_macro_to_mathjax()
.EXAMPLES:
sage: from sage.misc.latex_macros import sage_mathjax_macros sage: sage_mathjax_macros() ['ZZ: "\\\\Bold{Z}"', 'NN: "\\\\Bold{N}"', ...
