How to open a new file in the current directory with gvim on Windows?

Question

If I'm working on a file located on e.g. ~\myprojects\testproject\hello.txt and then want to open a new file in the same directory e.g. todo.txt (located on ~\myprojects\testproject\todo.txt), how can I do that efficiently with gvim on Windows?

Today I have to type this command, maybe using tab-completion for the paths:

:e ~\myprojects\testproject\todo.txt

Is there any shorter command e.g:

:e .\todo.txt

in gvim on Windows?

If I use .\todo.txt, that file will be located on C:\Windows\system32, that's not even my home directory. Is there any setting to specify my home directory as default instead? or any other diectory?

Answer 1

The following should work, provided your current dir is where the file is:

:e todo.txt

For the second question I don't know a good answer. You can of course do

:cd ~

every time you start up, or you could edit your vimrc to do that. It's a hack and not a good solution.

There's also 'autochdir' if you want to cd to the file every time. I found it here: http://vim.wikia.com/wiki/Set_working_directory_to_the_current_file

In your vimrc you would put in this line:

set autochdir

Edit2: add answer to second question

Answer 2

I have the following in my vimrc:

map <Leader>e :e <C-R>=expand("%:p:h") . "/" <CR>

This opens the command line, enters the 'e' command and pre-populates the file argument with the path to the file in the currently active buffer. The key is mapped to the backslash key by default.
