Is $SECURITYSESSIONID needed to check?

[delphinus]

I'm using NeoVim and know :SudoWrite cannot work by default settings. So I searched issues and found a workaround in #56 (comment) .

I tried this workaround but still it did not work. So I invested the source and found here.

vim-eunuch/plugin/eunuch.vim

Line 189 in 36c5974

let local_nvim = has('nvim') && len($DISPLAY . $SECURITYSESSIONID)

@tpope says this line detects the env is NeoVim in local ( #45 (comment) ). But is $SECURITYSESSIONID needed to check? At least in my env (macOS Mojave 10.14.6), $SECURITYSESSIONID is always empty even in local.

For a stopgap measure, I wrote below in init.vim and successfully :SudoWrite works! thx @TSFoster !

if $SECURITYSESSIONID == ''
  let $SECURITYSESSIONID = 'dummy'
endif
let $SUDO_ASKPASS = '/path/to/macos-askpass'

I borrowed this check from Git, which has since changed the conditional: git/git@be537e4. Does adding a check for $TERM_PROGRAM fix it?

Ah, I got the reason for the code clearly by the comment in git's commit. $DISPLAY . $SECURITYSESSIONID . $TERM_PROGRAM seems sufficient. I will PR for this.
