I use Emacs 24.2. I've installed js-comint
and js-mode
from MELPA, executed run-js
, and now in REPL instead of >
sign i have this gibberish:
^[[1G> ^[[0K^[[3G
The REPL itself in Inferior Javascript mode works just fine, just the >
sign is changed. If you enter unfinished expression, it even prints ^[[1G... ^[[0K^[[5G
. The ^[
are system characters, that are not copied with copy-paste, i add them for you to have an idea.
In my init-file:
(require 'js-comint)
(setq inferior-js-program-command "nodejs")
In terminal calling nodejs
produces working REPL.
Why prompt behaves this way? What should i do to correct this?
(setq inferior-js-mode-hook
(lambda ()
;; We like nice colors
(ansi-color-for-comint-mode-on)
;; Deal with some prompt nonsense
(add-to-list
'comint-preoutput-filter-functions
(lambda (output)
(replace-regexp-in-string "\033\\[[0-9]+[GK]" "" output)))))
\033
is the escape character it prints as ^[
.
Just add one line in your .emacs:
(setenv "NODE_NO_READLINE" "1")
Answer come from this post: Node.js prompt '>' can not show in eshell
Not sure how recent, but now one can download and use the nodejs-repl
.
