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 ^[.
