Command Line Tool

VimR comes with a command line tool vimr:

$ vimr file1 file2 ...        # opens file1, file2, ... in tabs in the front most window.
$ vimr -n file1 file2 ...     # opens file1, file2, ... in tabs in a new window.
$ vimr -s file1 file2 ...     # opens file1, file2, ... in separate new windows
$ vimr --nvim file1 file2 ... # forwards file1, file2, ... to the nvim process.
$ vimr --wait                 # vimr tool waits till the corresponding GUI window gets closed.
$ vimr --cwd /some/path       # set the working directory to /some/path
$ vimr -h                     # show help
usage: vimr [-h] [--dry-run] [--cwd CWD] [--wait] [--nvim] [-n | -s]
            [file [file ...]]

Open files in VimR: By default all files are open in tabs in the front most
window or in a new window if there is none. The working directory will be set
to the current directory.

  file

optional arguments:
  -h, --help  show this help message and exit
  --dry-run   Just print the 'open' command.
  --cwd CWD   Set the working directory.
  --wait      This command line tool will exit when the corresponding UI
              window is closed.
  --nvim      All other arguments (except --dry-run and --wait) will be passed
              over to nvim.
  -n          Open files in tabs in a new window.
  -s          Open files in separate windows.

For example to use VimR as git difftool, add the following to your ~/.gitconfig

[difftool "vimrdiff"]
    cmd = vimr --wait --nvim -d $LOCAL $REMOTE
[diff]
    tool = vimrdiff
