how to run Vim's :set command using vim --remote-expr
In Vim command-line mode, I can run :set invnumber to toggle line numbers on/off. Is there a way to run this command using the $ vim --remote-expr {expr} shell command? I know I can do this using $ vim --remote-send ':set invnumber<cr>'. But I want to know if I can do this using vim --remote-expr so I can build a more complicated command off of it.

You could make a function to do what you want, but assuming you don't want to do that for some reason, you can use the execute expression. This takes an Ex command, so you can just do:
$ vim --remote-expr "execute('set invnumber')"
You may want to do:
$ vim --remote-expr "execute('set invnumber|redraw')"
which just executes :set invnumber followed by :redraw. Otherwise, the setting will be changed, but you won't immediately see anything different until you change something.
Finally, you can use functions like getbufvar(<bufnr>, '&number') and setbufvar(<bufnr>, &number, <0|1>), similarly for getwinvar/setwinvar and some others. I don't think there's an easier way to toggle an option using these or similar functions other than setbufvar(<bufnr>, '&number', !getbufvar(<bufnr>, '&number)). These functions may be useful in the context of more complicated, programmatic processing.
