Do you write your blog posts using Vim? If you use Markdown, you might have noticed syntax highlighting is a bit off. I was wondering why that might be, when I found this very helpful thread on Stack Overflow.
Long story short: many of us use
.md as our Markdown extension, but Vim is recognizing that as a Modula file. This is very easily fixed by adding the following line to your
au BufNewFile,BufFilePre,BufRead *.md set filetype=markdown
And that's it.
