# org-clock-waybar – Export the currently clocked-in task to be displayed on Waybar
|
||
|
||
## Installation
|
||
|
||
Put `org-clock-waybar.el` somewhere in your `load-path`, and `(require 'org-clock-waybar)`.
|
||
|
||
MELPA version may come soon.
|
||
|
||
You can set the file to be written by customizing `org-clock-waybar-filename`; it defaults to
|
||
`$XDG_CACHE_HOME/waybar-current-task.json` (`$XDG_CACHE_HOME` defaults to `$HOME/.cache` on XDG
|
||
compatible systems, like Linux.)
|
||
|
||
## Waybar configuration
|
||
|
||
To add the current task to Waybar, add this snippet to your config:
|
||
|
||
```json
|
||
"custom/org": {
|
||
"format": " {}",
|
||
"return-type": "json",
|
||
"restart-interval": 5,
|
||
"exec": "cat /home/yourusername/.cache/waybar-current-task.json"
|
||
}
|
||
```
|
||
|
||
Then, add `custom/org` to `modules-left`/`modules-center`/`module-right` if your bar’s
|
||
configuration. You can find a minimal working configuration in the [`examples`](./examples)
|
||
directory.
|
||
|
||
### Additional Configuration
|
||
|
||
You can also display an icon specific to the clocked tasks category with the `format-icons` key:
|
||
|
||
```json
|
||
"custom/org": {
|
||
"format": "{icon} {}",
|
||
"return-type": "json",
|
||
"restart-interval": 1,
|
||
"format-icons": {
|
||
"refile": "",
|
||
"ToDo": "",
|
||
},
|
||
"exec": "cat /home/yourusername/.cache/waybar-current-task.json"
|
||
}
|
||
```
|
||
|
||
If you use Emacs as a daemon (e.g. starting it as `emacs --daemon` or calling `(server-start)`),
|
||
you can change the `exec` command to invoke `emacsclient` directly. Note that, since Emacsclient
|
||
can’t actually write stuff to the terminal, it will output an Emacs string full of backslashes
|
||
(see [this Emacs SE answer for details](https://emacs.stackexchange.com/a/28668/507)); thus, you
|
||
have to pipe the output through `jq fromjson`.
|
||
|
||
If you run emacs in this mode you can also eval commands on click, middle click or scroll.:
|
||
|
||
```json
|
||
"custom/org": {
|
||
"format": "{icon} {}",
|
||
"return-type": "json",
|
||
"restart-interval": 1,
|
||
"format-icons": {
|
||
"refile": "",
|
||
"ToDo": "",
|
||
},
|
||
"exec": "emacsclient --eval '(org-clock-waybar-ouptut-task)' | jq fromjson --unbuffered --compact-output",
|
||
"on-click": "emacsclient --eval '(org-clock-out)'",
|
||
"on-middle-click": "emacsclient --eval '(org-clock-in-last)'",
|
||
},
|
||
|
||
```
|
||
|
||
If you want the taskbar to show nothing or some other content if the emacs server is not running then you need to write a short bash script to catch when the emacsclient command returns a non-zero exit code. An example of this is:
|
||
|
||
```bash
|
||
#!/bin/bash
|
||
|
||
json=$(emacsclient --eval '(org-clock-waybar-ouptut-task)' 2> /dev/null)
|
||
status=$?
|
||
[ $status -eq 0 ] && echo $(echo $json | jq fromjson --unbuffered --compact-output) || echo ""
|
||
```
|
||
|
||
