# rofi-menu

Rofi allows defining custom modes ([see the spec](https://github.com/davatorium/rofi/wiki/mode-Specs)).

This lib is a reference implementation with some extra "sugar".

Features:

- simple menu definition via python
- extendable
- async in first place
- allows keeping state during rofi session

Simple demo:

![custom menu](https://github.com/miphreal/python-rofi-menu/raw/master/docs/demo.gif)

## Requirements

- rofi >= 1.5.4
- python >= 3.6

## Installation

Using pip

```sh
$ pip install rofi-menu
```

## Example

Create a python script which will be used for rofi mode
e.g. `example.py` (don't forget to mark it as executable -- `chmod +x ./example.py`)

Assuming you installed `rofi-menu` into a virtual environment (let's say it's `~/.pyenv/versions/rofi/bin/python`).
Make sure shebang points to the right python executable, e.g. `#!/home/user/pyenv/versions/rofi/bin/python`.

```python
#!/home/user/.pyenv/versions/rofi/bin/python
import rofi_menu

class ProjectsMenu(rofi_menu.Menu):
    prompt = "Projects"
    items = [
        rofi_menu.BackItem(),
        rofi_menu.ShellItem("Project 1", "code-insiders ~/Develop/project1"),
        rofi_menu.ShellItem("Project 2", "code-insiders ~/Develop/project2"),
        rofi_menu.ShellItem("Project X", "code-insiders ~/Develop/projectx"),
    ]

class LogoutMenu(rofi_menu.Menu):
    prompt = "Logout"
    items = [
        rofi_menu.ShellItem("Yes", "i3-msg exit", flags={rofi_menu.FLAG_STYLE_URGENT}),
        rofi_menu.ExitItem("No", flags={rofi_menu.FLAG_STYLE_ACTIVE}),
    ]

class MainMenu(rofi_menu.Menu):
    prompt = "menu"
    items = [
        rofi_menu.TouchpadItem(),
        rofi_menu.NestedMenu("Projects >", ProjectsMenu()),
        rofi_menu.ShellItem(
            "Downloads (show size)", "du -csh ~/Downloads", show_output=True
        ),
        rofi_menu.NestedMenu("Second monitor", rofi_menu.SecondMonitorMenu()),
        rofi_menu.ShellItem("Lock screen", "i3lock -i ~/.config/i3/bg.png"),
        rofi_menu.ShellItem("Sleep", "systemctl suspend"),
        rofi_menu.NestedMenu("Logout", LogoutMenu()),
    ]

if __name__ == "__main__":
    rofi_menu.run(MainMenu(), rofi_version="1.6")  # change to 1.5 if you use older rofi version
```

Run it as:

```sh
$ rofi -modi mymenu:/path/to/example.py -show mymenu -show-icons
```

It'll result in

    async def load(self, meta):
        await super().load(meta)
        self.state = self.state or 0
        meta.session.setdefault("counter_total", 0)

        self.state += 1
        meta.session["counter_total"] += 1
        return await super().on_select(meta)

        per_menu_item = self.state
        total = meta.session["counter_total"]
        return f"🏃 Selected #{per_menu_item} time(s) (across menu items #{total})"

class HandleUserInputMenu(rofi_menu.Menu):
    allow_user_input = True

class CustomItem(rofi_menu.Item):
        async def render(self, meta):
            entered_text = meta.session.get("text", "[ no text ]")
            return f"You entered: {entered_text}"

items = [CustomItem()]

async def on_user_input(self, meta):
        meta.session['text'] = meta.user_input
        return rofi_menu.Operation(rofi_menu.OP_REFRESH_MENU)

main_menu = rofi_menu.Menu(
    prompt="menu",
    items=[
        OutputSomeTextItem("Output anything"),
        DoAndExitItem("Do something and exit"),
        CurrentDatetimeItem(),
        CounterItem(),
        CounterItem(),
        rofi_menu.NestedMenu("User input", HandleUserInputMenu()),
    ],
)

if __name__ == "__main__":
    rofi_menu.run(main_menu)
```
