如何配置“较少"以显示格式化的降价文件?

问题描述

我希望 less 以某种格式显示 *.md 降价文件-就像我知道 less 可以用于手册页一样，等等.我正在运行Ubuntu 12.04.

I would like to have less display *.md markdown files with some formatting -- like I know less can, for manpages, etc. I am running Ubuntu 12.04.

我尽可能将用户定义的过滤器放入 .lessfilter :

#!/bin/sh
case "$1" in
  *.md)
    fn=/tmp/$1.$$.html
    markdown "$1" | html2txt > $fn  ### LOSES FORMATTING
    cat $fn                         ### TO STDOUT???
    ;;
  *)
  # We don't handle this format
  exit 1
esac
# No further processing by lesspipe necessary
exit 0

因此，主要问题是:

• 如何将一些基本格式设置信息也传递给 less ，而不是因为 html2txt
而丢失
• 仅将新内容打印到 stdout 是否正确?还是我可以将 *.html 写入文件磁盘，并让 less 自行处理该html(查看html扩展名并对其进行操作?)

• How can I pass some basic formatting information to less as well, instead of losing it with html2txt
• Is it correct to just print the new content to stdout? Or could I just write the *.html to file disk and let less handle that html at its own digression (seeing the html-extension and acting on it?)

推荐答案

看看 Pandoc .它可以将文件从markdown格式转换为groff手册页，然后可以在 man 中查看.

Take a look at Pandoc. It can convert files from markdown format to groff man pages which you can then view in man.

您的 .lessfilter 脚本为:

case "$1" in
  *.md)
    pandoc -s -f markdown -t man "$1" | man -l -
    ;;

或者，使用 markdown 命令将其转换为html，然后使用 lynx 浏览器进行查看，但这对我来说并不是很好.

Alternatively, convert it to html using the markdown command and then use the lynx browser to view it, but this didn't work too well for me.

case "$1" in
  *.md)
    markdown "$1" | lynx -stdin
    ;;

是的， lessfilter 脚本必须写入标准输出.

And, yes, the lessfilter script must write to stdout.
