lstlean.tex
|
|
===========
|
|
|
|
The file `lstlean.tex` contains /Lean/ style definitions for the
|
|
`listings` package, which can be used to typeset Lean code in a
|
|
Latex document. For more information, see the documentation for the
|
|
`listings` package and the sample document `sample.tex`.
|
|
|
|
You need the following packages installed:
|
|
|
|
- `listings`
|
|
- `inputenc`
|
|
- `color`
|
|
|
|
Because `listings` does not work well with unicode, the style
|
|
replaces all unicode characters with Latex equivalents. Some of the
|
|
replacment symbols require the `amssymb` package.
|
|
|
|
To use the style, all you need to do is include `lstlean.tex` in
|
|
the same directory as your Latex source, and include the following
|
|
preamble in your document:
|
|
```
|
|
\documentclass{article}
|
|
|
|
\usepackage[utf8x]{inputenc}
|
|
\usepackage{amssymb}
|
|
|
|
\usepackage{color}
|
|
\definecolor{keywordcolor}{rgb}{0.7, 0.1, 0.1} % red
|
|
\definecolor{tacticcolor}{rgb}{0.1, 0.2, 0.6} % blue
|
|
\definecolor{commentcolor}{rgb}{0.4, 0.4, 0.4} % grey
|
|
\definecolor{symbolcolor}{rgb}{0.0, 0.1, 0.6} % blue
|
|
\definecolor{sortcolor}{rgb}{0.1, 0.5, 0.1} % green
|
|
\definecolor{attributecolor}{rgb}{0.7, 0.1, 0.1} % red
|
|
|
|
\usepackage{listings}
|
|
\def\lstlanguagefiles{lstlean.tex}
|
|
\lstset{language=lean}
|
|
```
|
|
|
|
The `inputenc` package is needed to handle unicode input. Of
|
|
course, you can set the colors any way you want. In your document,
|
|
you can then in-line code with the `\lstinline{...}`, and add a code
|
|
block with the `\begin{lstlisting} ... \end{lstlisting}`
|
|
environment.
|
|
|
|
Note that if you use a unicode symbol that is not currently handled in
|
|
`lstlean.tex`, you can simply add it to the list there, together
|
|
with the Latex equivalent you would like to use.
