1. I am trying to set up color prompt in asterisk CLI. In the documentation I have found this:

    %Cn[;n] Change terminal foreground (and optional background) color to specified. A full list of colors may be found in include/asterisk/term.h*

    But nowhere could I find what format the color code should be. I have tried all possible permutations, none of them works:

    ASTERISK_PROMPT="%Cn[COLOR_BLUE] %H: " asterisk -vvvvvvr
    ASTERISK_PROMPT="%Cn[32;128] %H: " asterisk -vvvvvvr
    ASTERISK_PROMPT="%Cn[32;] %H: " asterisk -vvvvvvr
    ASTERISK_PROMPT="%Cn[;32] %H: " asterisk -vvvvvvr
    ASTERISK_PROMPT="%Cn[;COLOR_CYAN] %H: " asterisk -vvvvvvr
    ASTERISK_PROMPT="%Cn[32|128] %H: " asterisk -vvvvvvr 

    can somebody please tell me how to make my asterisk prompt red, for example?

  2. Also, I have another issue with the CLI prompt:

    I am using Asterisk 11.13 on Debian Wheezy. When I am in asterisk CLI, I can use command history and "readline-like" functions such as CTRL+r to search. But not all functions are available. For example, the alternate mappings for "page up" and "page down" to search the history do not work. They work in everything else (bash, mysql, ..)

    $ cat /etc/inputrc
    "\e[5~": history-search-forward
    "\e[6~": history-search-backward

    is there a way to make it work in asterisk ?

  • I know nothing of asterisk, but is it possible that the documentation is trying to say "%C32", with the brackets indicating the optional background color? i.e, "%C32;128" – jbsmith Dec 5 '14 at 21:24

The "ASTERISK_PROMPT" is an environment variable and should be set prior to starting the CLI for it to take affect.


asterisk -r

As for your specific version, (Asterisk 11 branch) The reasons for not displaying colors is as follows:

  1. The command-line options to connect to the server includes the "no-color" flag.
  2. No "term" environment variable is defined.
  3. If the terminfo database exists, and either does not include a max_colors definition, or the value = 0.
  4. The "term" environment variable does not include one of the following:
    • "xterm"
    • "xterm-color"
    • "xterm-256color"
    • "Eterm"
    • "vt100"
    • "crt"

If any of those criteria are met... you won't get vt100 colors.

This information is taken directly from the source-code.

  • the export statement does not make any difference. When I prepend ASTERISK_PROMPT= before the asterisk command I can set prompt as well. I can change the text of the prompt, use %H, but the colors still do not work. – user1968963 Dec 6 '14 at 11:04
  • There are only a few things that would keep your console from displaying colors. 1) you did specify the "-n" (no color) parameter. 2) You are connecting using the "-c" (console) parameter. 3) you specified the "-f" (no-fork) parameter. 4) your shell does not support colors... or is missing the correct "TERM" environment variable. I believe the "TERM" needs to be set to one of the following: "linux", "xterm", "Eterm", "crt", or "vt"... and it also needs to be able to support vt100 colorings. – TheCompWiz Dec 8 '14 at 19:31
  • The specifics can be found in the term.c source-code. Specifically, look in the "term_init" function. doxygen.asterisk.org/trunk/d5/de5/… – TheCompWiz Dec 8 '14 at 19:33
  • The list is changed from 1.0 slightly. in trunk it looks for "TERM" to be set to: "linux", "xterm", "xterm-color", "xterm-256color", "Eterm", "vt100", or "crt". – TheCompWiz Dec 8 '14 at 19:40
  • I have TERM set to "xterm-256color". But even when I change it to "linux" it does not make any difference. I still get no color, even when I start asterisk as /usr/sbin/asterisk -r (to make sure there are no aliases) – user1968963 Dec 8 '14 at 23:57

For configuring the "readline-like" functionality check out what libedit offers You to configure in editrc (https://manpages.debian.org/jessie/libedit-dev/editrc.5.en.html).
Program name for configuration should be "asterisk" (if You want to change settings specially for this program).
