mu4e 1.0; emacs 26.1 |
(1) Open Emacs with emacs -Q
(2) Type the following code into *scratch*
(add-dir-local-variable
'c-mode
'eval
'(progn (make-local-variable 'process-environment)
(setq process-environment (copy-sequence process-environment))
(setenv "TEST" "hello")))
(3) M-x eval-buffer
Expected .dir-locals.el contents:
((c-mode (eval . (progn (make-local-variable 'process-environment)
(setq process-environment (copy-sequence
process-environment))
(setenv "TEST" "hello")))))
Actual contents:
((c-mode (eval progn (make-local-variable 'process-environment)
(setq process-environment (copy-sequence
process-environment))
(setenv "TEST" "hello"))))
When I open a C file and inspect process-environment, TEST is not set.
When I manually create a .dir-locals.el with the expected contents, it
works.
Please correct me if I'm using add-dir-local-variable wrong, I was not
able to find a version that works as expected with the above
progn. Strangely, if I use (progn (message "hello")), instead of the
progn with setenv, "hello" gets printed every time I open a C file.
