Vim_get_argv.md

As of 8.1.2233 Vim has v:argv available to represent the arguments Vim was invoked with as a list.

We can get an equivalent list on *NIX systems with the following, useful if the version of Vim does not support v:args.

split(system('ps -o command= -p' . getpid()))

We could use something like the following as a compatibility shim, though of course an extra condition for non *NIX systems is missing.

function! GetArgv() abort
  return exists('v:argv') ?
    \ v:argv :
    \ split(system('ps -o command= -p' . getpid()))
endfunction
