## Features
* Under 200 lines of code
* Doesn't run in the background, just displays the notification and exits
* No external dependencies except Xlib and Xft
* Configurable through `config.h` or Xresources ([using this patch](https://github.com/dudik/herbe/pull/11))
* [Actions support](#actions)
* Extensible through [patches](https://github.com/dudik/herbe/pulls?q=is%3Aopen+is%3Apr+label%3Apatch)

To create a new patch you'll have to open a pull request with your changes. Append `.diff` to the pull request URL to get a downloadable diff file. Don't forget to prefix the title with `patch:` and to apply the `patch` label to it. For inspiration, look at [my Xresources patch](https://github.com/dudik/herbe/pull/11). Thank you. * [Multiple notifications](#multiple-notifications)

### Dismiss a notification ### Dismiss a notification
A notification can be dismissed either by clicking on it with `DISMISS_BUTTON` (set in config.h, defaults to left mouse button) or sending a `SIGUSR1` signal to it: A notification can be dismissed either by clicking on it with `DISMISS_BUTTON` (set in config.h, defaults to left mouse button) or sending a `SIGUSR1` signal to it:

herbe is configured at compile-time by editing `config.h`. Every option should be self-explanatory. There is no `height` option because height is determined by font size and text padding. herbe is configured at compile-time by editing `config.h`. Every option should be self-explanatory.
