Thanks for the suggestion John.

So basically I need to run some of my own commands, like you have done
above.

But I am running into the following issue.

$ gvim.exe --servername DIFF -c "echo 1"
$ gvim.exe --servername DIFF -c "echo 2"

I was hoping the 2nd call to gvim would use the already running servername
DIFF, but it instead launches a new vim instance called DIFF1


So I tried some alternatives:

$ gvim.exe --servername DIFF --remote-send "echo 1"

This one tells me the vim instance DIFF isn't running (which it isn't).

$ gvim.exe --servername DIFF --remote-expr "echo 1"

Same with this one.


Basically, I am trying to do this in a Windows batch / cmd file:

function! DiffByTab( file1, file2 )
    echomsg 'F1:'.a:file1.'  F2:'.a:file2
    exec 'tabedit '.a:file1
    exec 'vert diffsplit '.a:file2
endfunction


start gvim.exe --servername DIFF -c ":call DiffByTab( '%1', '%2' )"

I have this working, but if I call it a second time with another set of
files, it just launches another instance of vim instead of using the one
specified by --servername.
