I'm trying to figure out the options for writing equations in reST, and the possibilities appear to be to use either itex2MML or the latexmath plugin from http://docutils.sourceforge.net/sandbox/jensj/latex_math/ However, it seems that the latex generated by rst2latexmath.py (in the tools directory of the link above) is incomplete. For example, running the commands (latex_math.txt from the docs directory): rst2latexmath.py latex_math.txt latex_math.tex pdflatex latex_math.tex complains about undefined symbols. To get latex_math.tex to build I have to apply this patch:  latex_math.tex.original 20110627 09:18:18.000000000 +0100 +++ latex_math.tex 20110627 09:18:43.000000000 +0100 @@ 14,9 +14,19 @@ %%% Custom LaTeX preamble % PDF Standard Fonts \usepackage{mathptmx} % Times +\usepackage{amsmath} +\usepackage{amsfonts} +\usepackage{amssymb} \usepackage[scaled=.90]{helvet} \usepackage{courier} +\let\amalg=\undefined +\let\coprod=\undefined +\DeclareSymbolFont{cmsymbols}{OMS}{cmsy}{m}{n} +\DeclareSymbolFont{cmlargesymbols}{OMX}{cmex}{m}{n} +\DeclareMathSymbol{\amalg}{\mathbin}{cmsymbols}{"71} +\DeclareMathSymbol{\coprod}{\mathop}{cmlargesymbols}{"60} + %%% User specified packages and stylesheets %%% Fallback definitions for Docutilsspecific commands Unfortunately, of course, I'm patching completely the wrong file here!

The builtin "math" directive and role will automatically load the amsmath package but still requires you to specify amssymb (or an alternative like txfonts) in the stylesheet argument, say :: rst2latex stylesheet=amssymb mathexample.txt mathexample.tex > +\let\amalg=\undefined > +\let\coprod=\undefined > +\DeclareSymbolFont{cmsymbols}{OMS}{cmsy}{m}{n} > +\DeclareSymbolFont{cmlargesymbols}{OMX}{cmex}{m}{n} > +\DeclareMathSymbol{\amalg}{\mathbin}{cmsymbols}{"71} > +\DeclareMathSymbol{\coprod}{\mathop}{cmlargesymbols}{"60} What is the intention of these redefinitions? Are these fixes or defining variants? > Unfortunately, of course, I'm patching completely the wrong file here! > So two questions: > 1.

Are these fixes or > defining variants? These are fixes. The problem is that mathptmx doesn't define \amalg, \coprod or \jmath, or more precisely defines them to generate errors. These lines are a fudge to pull in alternative (and perfectly workable) definitions directly from the original computer modern files. These lines are required because latex_math.txt uses \amalg and \coprod. The issue, presumably, is that these symbols don't have postscript forms, and for whatever reason the writers of mathptmx didn't want to do the fudge I'm doing here (despite the fact it works perfectly well, as far as I can tell). For reference, the third symbol \jmath requires these lines: \let\jmath=\undefined \DeclareSymbolFont{cmletters}{OML}{cmm}{m}{it} \DeclareMathSymbol{\jmath}{\mathord}{cmletters}{"7C} > Dont, use the development version of Docutils (SVN checkout or daily > snapshot).

Yes, seemed to get through just fine.  Please disregard stuff below.

While it works well, it might be too scary for font experts like the mathptmx author(s). But more generally: mathptmx is not suited for serious/heavy math use: 1 mix of Times letters with nonmatching CM nonalphanumerical symbols. 2 no bold. `mathptmx` was chosen as default font package following feature requests because it provides a well known "Base Postscript/PDF font" without further dependencies (LaTeX core package). At this time, there was no math support in Docutils. Anyone using more than just very basic math should also use a different font package. (A survey of free math typesetting packages (in German) with example pages is available at http://milde.users.sourceforge.net/Matheschriften/matheschriften.html.) Best consistency is achieved with stylesheet=lmodern,amssymb. Times can be used with e.g. stylesheet=txfonts or stylesheet=qtxmath. Another recommended choice is Utopia with stylesheet=fourier. Of course the stylesheet can be defined in a config file for a more permanent setting. Then, overwriting the "latex_preamble" is recommended, too. >> Dont, use the development version of Docutils (SVN checkout or daily >> snapshot). > Gosh, must be pretty recent: I only checked out my docutils build > literally a month ago! Strange: the first version was added 20101025 with the commit ``Support mathematics with a "math" role and directive``. Since then, math is documented in the local documentation. However, the documentation at Sourceforge seems to be far behind the current state.

BTW: Using rst2latexmath should no longer be required. Docutils supports "math" directive and role out of the box since release 0.8 (20110707). Günter
