" File: remoteOpen.vim
|

" Author: Srinath Avadhanula <srinath AT fastmail DOT fm>

" Description:
|
|
" Often times, an external program needs to open a file in gvim from the
|
|
" command line. However, it will not know if the file is already opened in a
|
|
" previous vim session. It is not sufficient to simply specify
|
|
"
|
|
" gvim --remote-silent <filename>
|
|
"
|
|
" because this simply opens up <filename> in the first remote gvim session it
|
|
" sees. This script provides a command RemoteOpen which is meant to be used
|
|
" from the command line as follows:
|
|
"
|
|
" gvim -c ":RemoteOpen +<lnum> <filename>"
|
|
"
|
|
" where <lnum> is the line-number you wish <filename> to open to. What will
|
|
" happen is that a new gvim will start up and enquire from all previous
|
|
" sessions if <filename> is already open in any of them. If it is, then it
|
|
" will edit the file in that session and bring it to the foreground and itself
|
|
" quit. Otherwise, it will not quit and instead open up the file for editing
|
|
" at <lnum>.
|
|
"
|
|
" This was mainly created to be used with Yap (the dvi previewer in miktex),
|
|
" so you can specify the program for "inverse search" as specified above.
|
|
" This ensures that the inverse search uses the correct gvim each time.
|
|
"
|
|
" Ofcourse, this requires vim with +clientserver. If not, then RemoteOpen just
|
|
" opens in the present session.
