perlbrew PATH in Emacs.app作者：gugod 發佈於：
Emacs.app on Mac is not launched with the same
$PATH set from bashrc/cshrc, which means perlbrew cannot work without some special treatments. One common problem is that
cperl-perldoc will not be able to find the module document correctly. If you're experiencing it, keep reading.
cperl-perldoc working, set the environment variable PATH inside
(load "cl-seq") ;;; Prepend perlbrew paths to exec-path (mapc (lambda (x) (add-to-list 'exec-path x)) (mapcar (lambda (x) (concat (getenv "HOME") x)) (list "/perl5/perlbrew/bin" "/perl5/perlbrew/perls/current/bin"))) ;;; set PATH to be the same as exec-path, clobber the old PATH value. (setenv "PATH" (reduce (lambda (a b) (concatenate 'string a ":" b)) exec-path))
cperl-perldoc should correctly invoke the
perldoc program in
PATH from now.
To verify that
exec-path setting is also working, try eval (
C-x C-e) this sexp in
(call-process "perl" nil t nil "-E" "say $^X")
The full path of current perl executable should be appeared in the
