# InputEvent
This script enhanced `input.conf` with better, conflict-free, low-latency event mechanism.
It allows mpv users to bind events by using this syntax in `input.conf`.
```ini
KEY command #event: event_name
```
Now the supported events are:
`press`, `release`, `repeat`, `click`, `double_click`, `triple_click`, `quatra_click`, `penta_click`
Compound events e.g. `click` will be emitted as soon as possible to get lowest latency.
## How to use?
1. Put [inputevent.lua](https://github.com/natural-harmonia-gropius/input-event/raw/master/inputevent.lua) into `~~/scripts`
2. Modify your `input.conf`, See [Examples](https://github.com/natural-harmonia-gropius/input-event#Examples) to get common uses
3. (Recommended) Append `input-doubleclick-time=200` to your `mpv.conf`, if you feel unresponsive due to clicking
## Examples
### Click to pause, Double click to fullscreen
```ini
MBTN_LEFT cycle pause #event: click
MBTN_LEFT cycle fullscreen #event: double_click
MBTN_LEFT_DBL ignore
```
Like Youtube, you can click to pause and double click to full screen.
But I'm an mpv user and I wanted to do the same, so I added these into input.conf.
```ini
MBTN_LEFT cycle pause
MBTN_LEFT_DBL cycle fullscreen
```
Hmm, it does work, but it also pauses when double click, and I don't want that.
So here is the solution.
### Press to speedup, Release to restore
```ini
SPACE cycle pause #event: click
SPACE no-osd set speed 4; set pause no #event: press
SPACE ignore #event: release
```
When you press the `SPACE` the playback speed will be 4x faster.
When you release it, changes will [automatically restore](https://github.com/natural-harmonia-gropius/input-event#how-does-the-auto-restore-on-release-works).
Of course, you can bind it to the right arrow key by simply replacing `SPACE` to `RIGHT`.
I just personally prefer the space.
[po5/evafast](https://github.com/po5/evafast) also does this and is more powerful.
if you want to use it while having custom keybind, this is an example of integrating it.
```ini
RIGHT seek 5 #event: click
RIGHT script-binding evafast/speedup #event: press
RIGHT script-binding evafast/slowdown #event: release
```
### Press to maximize/minimize volume
```ini
UP add volume 10 #event: click
UP set volume 100 #event: press
DOWN add volume -10 #event: click
DOWN set volume 0 #event: press
```
For the default volume adjustment, repeatedly pressing or holding is annoying, slow and imprecise.
Now just one step, press.
### Click to next/prev chapter, Press to next/prev playlist item
```ini
PGUP add chapter -1 #event: click
PGUP playlist-prev #event: press
PGDWN add chapter 1 #event: click
PGDWN playlist-next #event: press
```
It's convenient for 65-key keyboard users like me.
`HOME/END` need be a combination of `fn` + `PGUP/PGDN`, which is not easy to press.
### Press to display stats, Click to toggle
```ini
i script-binding stats/display-stats-toggle #event: click
i script-binding stats/display-stats #event: repeat
i script-binding stats/display-stats #event: press
```
Click to toggle displaying information and statistics (as default `shift+i`).
Press to display information and statistics (as default `i`).
The press line is not required, it just reduces the latency (Very little).
### Press to show uosc UI
```ini
MBTN_LEFT script-message-to uosc set-min-visibility 1 #event: press
MBTN_LEFT script-message-to uosc set-min-visibility 0 #event: release
```
Rather than click to show, click to hide it is more comfortable to show only when pressed.
Requires [tomasklaen/uosc](https://github.com/tomasklaen/uosc).
### Handling repeat, Make it have a different event than click
```ini
. frame-step; show-text "${estimated-frame-number}" #event: click
. set pause no #event: press
. set pause yes; show-text "${estimated-frame-number}" #event: release
. show-text "${estimated-frame-number}" #event: repeat
```
Here is an example of `frame-step`.
The click here is the same as the default behavior.
But the press of the default is stuttering, now the playback is smooth.
### Handling raw press，Make it have different click, double click events
```ini
PLAYPAUSE cycle pause #event: click
PLAYPAUSE playlist-next #event: double_click
```
Some headphones have a `PLAYPAUSE` button, click to play/pause and double click to play the next, just like some smart headphones.
[Press (the latter if key up/down can't be tracked)](https://mpv.io/manual/master/#lua-scripting-event) will be treated as a click.
## Ideas that are currently impossible
### Press LEFT to rewind
Unfortunately, mpv doesn't support rewind now.
### Press MBTN_RIGHT to start mouse gesture, Release to execute the action
Will not be implemented here, Gesture is a higher level feature.
I would prefer this script to be an infrastructure, A better idea is to call other scripts.

## How does the auto-restore on release works?
Writing the ignore command in the release event will enable automatic restore.
What if you just need to **ignore** the release? Just don't write the line of release event.
```ini
KEY ignore #event: release
```
In this example [press-to-speedup-release-to-restore](https://github.com/natural-harmonia-gropius/input-event#press-to-speedup-release-to-restore).
If you playing with `speed=0.5; pause=yes`, Press will change them to `speed=4; pause=no`.
When released, they will restore to `speed=0.5; pause=yes`.
When you press, the script will record the current value of properties that will be changed.
Then it executes the command in press.
When you release, it will change the value of these properties to the value of the record.
The [command-prefixes](https://mpv.io/manual/master/#input-command-prefixes) of press will be retained as is.
The restore for `no-osd set speed 4` will be `no-osd set speed 1`.
Only `set`, `cycle`, `add`, `multiply` are currently supported for auto-restore.
A warning will be given for unsupported commands, `command doesn't support auto restore.`.
But that doesn't mean it doesn't work at all, It will restore the reversible part.
```ini
SPACE set speed 4; show-text 1 #event: press
SPACE ignore #event: release
```
In the above example, the speed will be restored, show-text cannot and will not be restored.
## The native press (repeat) doesn't work?
Writing the ignore command in the repeat event will bring back the original behavior of repeat.
```ini
UP add volume 1 #event: click
UP ignore #event: repeat
```
In the above example, if you don't write `UP ignore #event: repeat`, you'll have to press frequently, which is too tiring.
## Extended support for property-expansion
- **Dangerous, use with caution**
The original property-expansion can only work for strings, but now supports inserting in all positions of the command.
This is a example of a smoother speedup.
```ini
SPACE cycle pause #event: click
SPACE no-osd set speed 1; set pause no #event: press
SPACE ignore #event: release
SPACE no-osd add speed ${?speed==4.00:0}${!speed==4.00:0.1}; show-text ${speed} #event: repeat
```
## Support for multiple configuration files
- For same key, any events in new config will overwrite all events in old config.
You can spread out the configuration files into multiple ones like this and load them together at runtime.
```ini
script-opts-add=inputevent-configs="input.conf,~~/test.conf,~~/test.json"
```
input.conf
```ini
SPACE cycle pause #event: click
SPACE set speed 2.0 #event: press
SPACE set speed 1.0 #event: release
```
test.conf
```ini
SPACE set speed 0.5 #event: press
SPACE set speed 1.0 #event: release
```
test.json
```json
[
{
"key": "SPACE",
"on": {
"click": "show-text click",
"double_click": "show-text double-click",
"penta_click": "show-text penta-click",
"press": "show-text pressed",
"quatra_click": "show-text quatra-click",
"release": "show-text released",
"repeat": "show-text repeat",
"triple_click": "show-text triple-click"
}
}
]
```
Also, it supports hot-reloading.
```ini
[fullscreen]
profile-cond=fullscreen
profile-restore=copy-equal
script-opts-add=inputevent-configs="input.conf,~~/test.json"
```
## How to integrate with other scripts?
- For same key, events will be merged with existing events.
Here's an example
press `Z` to bind the key, press `C` to test the event execution and press `X` to unbind.
Save it as `test.lua` in your ~~/scripts
```lua
local utils = require("mp.utils")
local key = "c"
local on = {
click = "show-text click",
double_click = "show-text double-click",
triple_click = "show-text triple-click",
quatra_click = "show-text quatra-click",
penta_click = "show-text penta-click",
press = "show-text pressed",
release = "show-text released",
["repeat"] = "show-text repeat",
}
function bind()
local json, err = utils.format_json(on)
mp.commandv('script-message-to', 'inputevent', 'bind', key, json)
end
function unbind()
mp.commandv('script-message-to', 'inputevent', 'unbind', key)
end
mp.add_forced_key_binding("z", "test-z", bind)
mp.add_forced_key_binding("x", "test-x", unbind)
```
