I use Markdown on my blog for posts and comments, and I post at other sites that use Markdown (e.g. Stack Overflow). In Markdown, text indented four spaces is displayed as code, in pre tags.
I find myself often writing code in Vim or Emacs and needing to copy/paste it into a browser in a Markdown-suitable way.it back. This is easy to do in Vim and Emacs, only a few keystrokes. But "a few" is still greater than "one", so the heck with that. Let's script it.
This keymapping in Vim will do it all for me:
One clumsy thing about Vim is needing to restore the previous visual selection after each regex-replacement. I could use the marks '< and '> as ranges to
:s instead, but that's more typing than simply doing gv in the mapping. Copying to the system clipboard is easy because Vim has a register "+ for that purpose.
This took me maybe 45 seconds to write, probably due to being pretty familiar with Vim already. But in Vim, mappings are easy. You just type the characters that you'd type if you were doing it manually.
