Hi List,

the manual says

  | load returns t if the file loads successfully

but I would rather like to write a (big) Elisp expression into a file,
load the file, and get the expression's return value instead of just

Something like

| (eval-buffer (find-file ...))

does not do the job either.

(eval (read (find-file-noselect "/my/file.el")))

Did I overlook the simple and canonical way to do this?
This is mainly to avoid that shell commands like

| $ emacsclient -s my-server -e "( ... elisp expressions ...)"

become too long, and thus replace them with something like:

| $ emacsclient -s my-server -e "(load-file \"/my/file.el\")"

where /my/file.el contains those elisp expressions.

Of course, (eval-buffer (find-file-noselect "/my/file.el")) works in this
context as well, because the result of the -e EXPRESSION is discarded anyway.

Which leads back to emacsclient -l "/my/file.el"
