Add vim modeline in markdown document

Question

I would like to know how to use vim modelines in a Markdown document. Is it possible, or does modelines only recognise certain comment markers?

I have tried using this as the first line of my file:

<!-- vim: set ft=markdown -->

I also tried all these suggestions here with no luck.

Answer 1

Your modeline syntax is off. Add a colon at the end, and it will work:

<!-- vim: set ft=markdown: -->

Modeline doesn't care about comment markers. There are two different modeline formats:

• [text]{white}{vi:|vim:|ex:}[white]{options}

  This form does not use the keyword set, does not require a final colon, and most importantly, does not allow random text after options (such as -->). This means, any paired comment markers must necessarily use the second form:

• [text]{white}{vi:|vim:|Vim:|ex:}[white]se[t] {options}:[text]

  This form requires the use of set keyword, requires terminating options with a colon (:), and allows the terminating colon to be followed by random text.

Answer 2

I apply some markdown related settings according to the autocmd + filetype.

In my vimrc I have:

if has("autocmd")
    autocmd FileType markdown vmap <Leader><Bslash> :EasyAlign*<Bar><Enter>
endif

Not sure that it's the most traditional way.
