How can I edit my VIM config so that Vim treats ".ejs" files the same as it currently treats my html files?

What do I put in my vim conf开发者_如何学Cig? How do I change it?

I want it to be like .html extension...because it is html...

I think you need

au BufRead,BufNewFile *.ejs setfiletype html

au is short for autocmd

docs

It's also a good idea to put it inside a test

if has("autocmd")
    au BufRead,BufNewFile *.ejs setfiletype html
endif

To avoid error messages if you ever use a cut-down version of Vim that doesn't support this feature.

Finally, if you have a default filetype rule like:

au BufRead,BufNewFile * setfiletype text

then the *.ejs rule must be above it.

This worked well for me:

au BufEnter *.ejs :setl filetype=html

Digging into the vim docs

1. BufEnter - "After entering a buffer. Useful for setting options for a file type. Also executed when starting to edit a buffer, after the BufReadPost autocommands." source: BufEnter

2. :setl - "Like :set but set only the value local to the current buffer or window. Not all options have a local value. If the option does not have a local value the global value is set..." source: :setlocal
