如何在 python 中格式化 LaTeX 字符串?

问题描述

我正在编写一个应用程序，其部分功能是生成 LaTeX CV，所以我发现自己遇到了这样的字符串

I'm writing an application, part of whose functionality is to generate LaTeX CVs, so I find myself in a situation where I have strings like

egin{document}
	itle{Papers by AUTHOR}
author{}
date{}
maketitle
egin{enumerate}

%%   LIST OF PAPERS
%%   Please comment out anything between here and the
%%   first item
%%   Please send any updates or corrections to the list to
%%   XXXEMAIL???XXX

%usepackage[pdftex, ...

我想用动态信息填充，例如一个电子邮件地址.由于 LaTeX 本身的格式，带有 {email} 语法的 .format 将不起作用，也不会使用带有 %(email)s 语法的字典.特别是，像egin{document}"(LaTeX 中的命令)这样的字符串应该保持原样，而不是从 .format 中替换，并且像%%"(LaTeX 中的注释)这样的字符串也应该是左，没有从填充字典中替换.这样做的合理方法是什么?

which I would like to populate with dynamic information, e.g. an email address. Due to the format of LaTeX itself, .format with the {email} syntax won't work, and neither will using a dictionary with the %(email)s syntax. in particular, strings like "egin{document}" (a command in LaTeX) should be left literally as they are, without replacement from .format, and strings like "%%" (a comment in LaTeX) should also be left, without replacement from a populating dictionary. What's a reasonable way to do this?

推荐答案

为什么这行不通?

>>> output = r'author{{email}}'.format(email='user@example.org')
>>> print output
author{email}

编辑:使用双花括号转义"只有 LaTeX 理解的文字花括号:

edit: Use double curly braces to "escape" literal curly braces that only LaTeX understands:

>>> output = r'egin{{document}} ... author{{{email}}}'.format(
... email='user@example.org')
>>> print output
egin{document} ... author{user@example.org}
