Why is my function in .vimrc called automatically?
As I know we could define a function in .vimrc like below:
function Fun()
do something here
endfunction
Then we could call it like :call Fun()
.
For one of my systems, there is only a function definition in my .vimrc, however the function is always called as soon as I get into vim. Why?
Below is my vim version:
# vi --version

And my .vimrc:
# cat ~/.vimrc
function Fun1()
:!ls
endfunction
The function name doesn't matter, I changed the name as a test.
Update as of July 8, 2015:
As per the answer from Ben, and since I want my .vimrc to be cross-environment compatible, I complete the function definition if has('eval')...endif
as my final solution:
if has('eval')
function! Fun1()
do something
endfunction
endif

Your vim is compiled without "eval" support. This means that your Vim does not support defining functions. Therefore, the opening command is function Fun1()
invalid and ignored. The function definition is then executed because these are valid commands.
You will need to install a more fully featured Vim, or compile your own Vim, or find an alternative Vim installation on your system that has more capabilities. "eval" comes with the NORMAL feature set or more.
