# Compatibility executable script for applications running dmenu, which

|
# dmenu is just for simple prompts, using the `-p` flag. and wofi does fully
|
|
# support this usage.

# Wrapper script for menu application independent prompts. This script will pick

usage: menuprompt
|
|
Menuprompt is a wrapper script for menu application independent prompt (dmenu/rofi/wofi)
|
|
|
|
options:
|
|
-h, --help show this help message and exit
|
|
-p, --prompt [MESSAGE] Prompt to be displayed in the menu
|
|
-a, --app [MENU_APP] Overrides the app picked by default, must be one of supported apps
|
|
-v, --verbose Show debug information (printed to stderr to retain pipeable stdout output)
|
|
-vv, --very-verbose Show even more debug information
|
|
--dry-run Don't actually run the final menu command (only useful with --verbose)
|
|
|
|
actions:
|
|
-c, --choose
|
|
Basic pick prompt, picking from piped newline separated options
|
|
The picked option will be printed to stdout.
|
|
usage: printf 'No\nYes' | menuprompt -c -p 'Pick one: '
|
|
-yn, --yesno
|
|
Essentially an alias for printf 'No\nYes' | menuprompt -p "\$1", however instead of printing the result
|
|
to stdout, this instead exits with code 0 on success, 1 on failure, or 2 on getting other input. This
|
|
allows for easily combining it with other applications through chaining.
|
|
example: menuprompt --yesno && poweroff or menuprompt -yn -p "Do you really want to quit?" && killall Hyprland
|
|
-P, --password
|
|
Password prompt - hides the input characters
|
|
example: menuprompt -P -p "Enter password:" | xargs -I {} echo "Hah, got your password: {}"
|
|
|
|
supported menu applications and their actions:
|
|
dmenu:
|
|
- choose: supported
|
|
- yesno: supported
|
|
- password: supported, but requires password patch for -P argument
|
|
wofi:
|
|
- choose: supported
|
|
- yesno: supported
|
|
- password: supported, however setting --prompt won't have any effect
|
|
rofi:
|
|
- choose: supported
|
|
- yesno: supported
|
|
- password: not supported - no option for hidden input
|
|
|
|
|
|
passing custom arguments to menu app:
|
|
Note that when passing extra arguments, you should always explicity specify the menu application to use
|
|
as it's not guaranteed that all supported args will support given extra argument(s), nor that if they do
|
|
their support is consistent and the same argument does the same thing.
|
|
|
|
examples:
|
|
Make dmenu run on the bottom of the screen:
|
|
printf "A\nB\nC" menuprompt --app dmenu --choose -- -b
|
|
|
|
Run wofi with 20% width on the yesno prompt:
|
|
menuprompt --yesno -p "Do you really want to quit?" --app wofi -- --width=20%
|
|
|
|
|
|
exit codes:
|
|
0: Menu app ran successfully, action completed
|
|
1-2: Action specific
|
|
3: User error - invalid usage
|
|
4: Unable to pick menu app (no usable menu app installed?)
|
|
5: Internal menuprompt error, report this!
