It's a very lightweight program to show a popup with the translation of the selected text. It uses [sdcv](https://github.com/Dushistov/sdcv) for the dictionary lookup and a slightly modified version of [herbe](https://github.com/dudik/herbe) to display the popup.
|
||||
|
||||
## 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)
|
||||
## Dependencies
|
||||
xclip, sdcv

## Setup
|
||||
Compile with `make` and place `dictpopup` as well as `popup` in your PATH.
|
||||
|
||||
## Usage
|
||||
|
||||
### Patches
|
||||
[List of available 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.
|
||||
|
||||
_Note: This patching method was heavily inspired by [dylan's sowm](https://github.com/dylanaraps/sowm)._
|
||||
|
||||
### 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:
|
||||
```shell
|
||||
$ pkill -SIGUSR1 herbe
|
||||
```
|
||||
Dismissed notifications return exit code 2.
|
||||
|
||||
### Actions
|
||||
Action is a piece of shell code that runs when a notification gets accepted. Accepting a notification is the same as dismissing it, but you have to use either `ACTION_BUTTON` (defaults to right mouse button) or the `SIGUSR2` signal.
|
||||
An accepted notification always returns exit code 0. To specify an action:
|
||||
```shell
|
||||
$ herbe "Notification body" && echo "This is an action"
|
||||
```
|
||||
Where everything after `&&` is the action and will get executed after the notification gets accepted.
|
||||
|
||||
### Newlines
|
||||
Every command line argument gets printed on a separate line by default e.g.:
|
||||
```shell
|
||||
$ herbe "First line" "Second line" "Third line" ...
|
||||
```
|
||||
You can also use `\n` e.g. in `bash`:
|
||||
```shell
|
||||
$ herbe $'First line\nSecond line\nThird line'
|
||||
```
|
||||
But by default `herbe` prints `\n` literally:
|
||||
```shell
|
||||
$ herbe "First line\nStill the first line"
|
||||
```
|
||||
Output of other programs will get printed correctly, just make sure to escape it (so you don't end up with every word on a separate line):
|
||||
```shell
|
||||
$ herbe "$(ps axch -o cmd:15,%cpu --sort=-%cpu | head)"
|
||||
```
|
||||
|
||||
### Multiple notifications
|
||||
Notifications are put in a queue and shown one after another in order of creation (first in, first out). They don't overlap and each one is shown for its entire duration.
|
||||
|
||||
### Notifications don't show up
|
||||
Most likely a running notification got terminated forcefully (SIGKILL or any uncaught signal) which caused the semaphore not getting unlocked. First, kill any `herbe` instance that is stuck:
|
||||
```shell
|
||||
$ pkill -SIGKILL herbe
|
||||
```
|
||||
Then just call `herbe` without any arguments:
|
||||
```shell
|
||||
$ herbe
|
||||
```
|
||||
Notifications should now show up as expected.
|
||||
|
||||
Don't ever send any signals to `herbe` except these:
|
||||
```shell
|
||||
# same as pkill -SIGTERM herbe, terminates every running herbe process
|
||||
$ pkill herbe
|
||||
|
||||
$ pkill -SIGUSR1 herbe
|
||||
$ pkill -SIGUSR2 herbe
|
||||
```
|
||||
And you should be fine. That's all you really need to interact with `herbe`.
|
||||
|
||||
## Installation
|
||||
### Packages
|
||||
[](https://repology.org/project/herbe/versions)
|
||||
|
||||
[OpenBSD patch](https://github.com/dudik/herbe/pull/4)
|
||||
|
||||
[FreeBSD patch](https://github.com/dudik/herbe/pull/16)
|
||||
|
||||
[Wayland port](https://github.com/muevoid/Wayherb) by [muevoid](https://github.com/muevoid)
|
||||
|
||||
**Only the [herbe-git AUR package](https://aur.archlinux.org/packages/herbe-git/) is maintained by me.**
|
||||
|
||||
### Dependencies
|
||||
* X11 (Xlib)
|
||||
* Xft
|
||||
|
||||
The names of packages are different depending on which distribution you use.
|
||||
For example, if you use [Void Linux](https://voidlinux.org/) you will have to install these dependencies:
|
||||
```shell
|
||||
sudo xbps-install base-devel libX11-devel libXft-devel
|
||||
```
|
||||
|
||||
### Build
|
||||
```shell
|
||||
git clone https://github.com/dudik/herbe
|
||||
cd herbe
|
||||
sudo make install
|
||||
```
|
||||
`make install` requires root privileges because it copies the resulting binary to `/usr/local/bin`. This makes `herbe` accessible globally.
|
||||
|
||||
You can also use `make clean` to remove the binary from the build folder, `sudo make uninstall` to remove the binary from `/usr/local/bin` or just `make` to build the binary locally.
|
||||
|
||||
## Configuration
|
||||
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.

||||

||||

## Contribute
|
||||
If you want to report a bug or you have a feature request, feel free to [open an issue](https://github.com/dudik/herbe/issues).
|
||||
|
||||
## Projects with herbe integration
|
||||
- [qutebrowser](https://qutebrowser.org/) supports showing web notifications via herbe, via the `content.notifications.presenter` setting.
|
||||
call `dictpopup` to translate and display the popup of the selected text.
|
||||
You can also use `popup` like `popup "Hello"` for other things.
