cool vim tips and tricks you might not know

Vim has tons of awesome shortcuts and features you pick up over time. Some of those I don’t use every day so I have to write them down so I can look them back up when I can’t remember exactly how it works. Instead of keeping them locked away in a text file, I’ll throw them online here and spread the Vim love. None of these need any special plugins. They should all work right out of the box with plain old Vim.

If you want to know more about a specific command listed here, use the Vim :help command to find out more. There are usually more options and possibilities for each of these commands and the Vim documentation is excellent.

Here we go!

When you are on the command line using a console application and you want to edit the output in Vim right away, or open that long list of possible command line switches in Vim for reference, this one will come in handy.
I’m using GVim here because since that opens in a separate window from your shell, this is the most useful.

ls *.txt | gvim -
docker -h | gvim -
git --help | gvim -

This one is for opening a ton of files in a single Vim instance from Powershell, in different tabs. This means you are running this from a Powershell console of course.

gvim -p (ls *.ps1)

For more Vim command line options run this in your favorite shell environment:

vim -h
gvim -h

How about opening a remote file, or fetch HTML from a page over HTTP using Vim:


When you work with log files a lot, being able to delete lines containing or not containing a specific word can be just what you need.
These two commands are perfect to filter out obsolete exceptions and figure out what is causing that nasty production issue:


Did you know that Vim has a spell checker? I didn’t know that at the beginning (try :h spell for more details).
To activate/deactivate:

:set (no)spell

To jump to the next / previous misspelled word:


To get a list of spelling suggestions (or use the mouse in GVim, which is quite practical):


You can add a simple XML-tidy shortcut to your .vimrc file by adding the following command.
What it does is setting the file type to XML, removes spaces between opening & closing brackets, add a return character in-between the opening & closing brackets and finally formats the document so it looks all nice and indented.

nmap <leader>ppx <Esc>:set filetype=xml<CR>:%s/> *</></g<CR>:%s/></>\r</g<CR><ESC>gg=G<Esc>:noh<CR>

You can force syntax highlighting in Vim as follows for e.g. HTML, XML and Markdown.
Of course this works for a ton of other file types as well, as long as you can figure out what the extension/file type key is. But that’s pretty easy in most cases.

:set syntax=html
:set syntax=xml
:set syntax=md

I add shortcuts for any files I frequently edit by using the leader key and a letter combination that’s easy to remember.
For example this one to edit my custom .vimrc file when I press the leader key followed by “e” and “v” (edit vimrc).

nnoremap <Leader>ev :tabe ~\vimfiles\nj-vimrc.vim<CR>

That’s about it. For more nice Vim tips check out more Vim posts. Another good resource for bite sized Vim tips is the MasteringVim on twitter and it’s newsletter.
