## Installation

- Copy script somewhere into $PATH
- Archlinux: [Arch Packages][3]
- Gentoo: [Woomy Overlay][4]
- Nix: [Nix Packages][9]

- Run `./networkmanager_dmenu` in your terminal to generate the config file. 
 
## Requirements

1. Python 3.7+
2. NetworkManager
3. Dmenu (X), Rofi (X or XWayland), Wofi (Wayland) or Bemenu (X or Wayland)
4. Python gobject (PyGObject, python-gobject, etc.)
5. (Debian/Ubuntu based distros) libnm0 (libnm-util-dev on older distributions)
   and gir1.2-nm-1.0 (you have to explicitly install the latter on Debian Sid)
6. (optional) The network-manager-applet or nm-connection-editor package,
   depending on distro (in order to launch the GUI connection editor, if
   desired. The applet does _not_ need to be started.)
7. (optional) Pinentry. Make sure to set which flavor of pinentry command to use
   in the config file.
8. (optional) ModemManager for WWAN support.
9. (optional) notify-send (libnotify) for notifications (connected,
   disconnected, etc.)
10. (optional) bluez package for bluetooth control

## Configuration 

### Initial Setup

- Run `./networkmanager_dmenu` in your terminal to generate the config file.
  Checks for installed launchers and terminals and prompts for selection. The
  generated config file will be created at:
  `~/.config/networkmanager-dmenu/config.ini`

### Custom Configuration

- To customize behavior further, edit the generated configuration file
- You can also manually copy config.ini.example to
  ~/.config/networkmanager-dmenu/config.ini and edit it directly
- Alternatively, specify a custom config file location using:
  - Command line: `--config /path/to/config.ini`
  - Environment variable: `NM_DMENU_CONFIG=/path/to/config.ini
    networkmanager_dmenu`
  - The command line flag takes precedence over the environment variable
- All theming is done through the respective menu programs. Set `dmenu_command`
  with the desired options, including things like `-i` for case insensitivity.
  See config.ini.example for examples.
    * Note: if a literal `%` is used in the config, it must be entered as `%%`.
      See config.ini.example.
- If using dmenu for passphrase entry (pinentry not set), dmenu options in the
  `[dmenu_passphrase]` section of config.ini will set the normal foreground and
  background colors to be the same to obscure the passphrase. The [Suckless
  password patch][6] `-P` option is supported if that patch is installed. Rofi,
  Wofi and Bemenu will use their respective flags for passphrase entry.
- Set default terminal (xterm, urxvtc, etc.) command in config.ini.
- Configure `show_pass` to run `nmcli dev wifi show-password` in a terminal.
  This may take some experimentation to determine what will work for your
  terminal.
- Saved connections can be listed if desired. Set `list_saved = True` under
  `[dmenu]` in config.ini. If set to `False`, saved connections are still
  accessible under a "Saved connections" sub-menu.
- If desired, copy the networkmanager_dmenu.desktop to /usr/share/applications
  or ~/.local/share/applications.
- If you want to run the script as $USER instead of ROOT
    1. Set [PolicyKit permissions][5]. The script is usable for connecting to
    pre-existing connections without setting these, but you won't be able to
    enable/disable networking or add new connections.
- For bluetooth control, there are two options:
    1. If bluez is installed and the bluetooth service is running, no further
    action is needed.
    2. If not, the user needs to have access to `/dev/rfkill`. On some distros
    (e.g. Archlinux), `/dev/rfkill` belongs to a group such as `rfkill`. In this
    case, ensure $USER belongs to that group. For other distros (e.g. Fedora),
    you can use udev to ensure `/dev/rfkill` belongs to a group. For example,
    create `/etc/udev/rules.d/10-rfkill.rules`:

               KERNEL=="rfkill", GROUP="wheel", MODE="0664"
    
       and then ensure $USER belongs to the `wheel` group.

## Usage

`networkmanager_dmenu [-h] [--config CONFIG_PATH] <menu args>`

- Run script or bind to keystroke combination
- If desired, menu options can be passed on the command line instead of or in
  addition to the config file. These will override options in the config file.
- Networkmanager_dmenu cannot create hotspots, but can manage existing ones. To
  create a new NetworkManager hotspot and show a QR Code with the password:

```bash
nmcli device wifi hotspot ifname wlp0s20f3 ssid testing password pass123456 band a
nmcli connection up hotspot (or use networkmanager_dmenu to enable)
nmcli device wifi show-password
```

  This may not work for your setup.  [Linux-wifi-hotspot][10] is an option if straight
  NetworkManager wifi sharing doesn't work for you.  Unfortunately, these
  hotspots cannot be managed with networkmanager_dmenu.

* **NOTE** Running under [UWSM][12] requires some [extra configuration][13].
    + Assigning to keyboard shortcut: `uwsm app -- networkmanager_dmenu`
    + If launching by, for example, clicking a Waybar icon, Waybar must be the
      version that works with UWSM and be started as a `systemd --user` service.
