Information

Enables universal autoscroll.

Pretty pointless since on Linux you can achieve it using config files (see the example) and for Windows there are usually drivers.

Supports only mouse buttons.

The package requires pynput to work, to display an icon you need to install pyside6 (qt6 package).

pip install autoscroll pyside6

built-in icon:

Usage

By default, the icon is disabled, to enable it pass --icon-enable.

You can pass file contents as command line arguments using @path/to/the/file syntax. Arguments in that case can be placed wherever - on one line, on several lines.

If you want to dynamically pass runtime arguments (without restarting the process), you can use --config options for it.

Once you press --buttons-start, you can scroll vertically or horizontally just by moving your mouse untill you press --buttons-end.

If --buttons-hold is set, the srolling ends once you release --buttons-start.

Once --buttons-start is pressed, the scroll thread starts looping. Every loop consists of sleeping for an interval, then scrolling for either 0, 1, or -1 pixels on both axis towards the starting point. Starting point is the point where --buttons-start was pressed. Sleep interval is recalculated on every mouse move as such:

    100 / (--scrolling-acceleration * max(distance) + --scrolling-speed)

If --scrolling-acceleration is not 0, the speed of scrolling will be faster the farther away you are from the starting point. If --scrolling-acceleration is 0, the speed of scrolling will be constant.

examples

start from the package
python3 -m venv venv
. venv/bin/activate
pip install autoscroll pyside6
autoscroll
start from the repository
python3 -m venv venv
. venv/bin/activate
git clone https://github.com/kongrentian/autoscroll.git
pip install -r autoscroll/requirements.txt
python3 -m autoscroll
start with command line options
autoscroll --buttons-start 1 --debug-click --icon-disable
start with the configuration file passed once
autoscroll --icon-enable @config.txt

If config.txt is defined like this, its contents will be used as command line arguments - they will be loaded only once. Arguments can be placed wherever - on one line, on several lines. For example,

--buttons-start 1
--buttons-hold --debug-click
start with the process listening to the changes in the configuration file
autoscroll --config-enable --config-path config.txt

If config.txt is defined like this, the process will listen for changes in that file and update itself. Arguments can be placed wherever - on one line, on several lines The file is checked for changess every --config-interval. For example:

--buttons-start 1 --buttons-hold
--debug_click

Enables universal autoscroll.

Pretty pointless since on Linux you can achieve it using config files and for Windows there are usually drivers.

Supports only mouse buttons.

The package requires 'pynput' to work, to display an icon you need to install 'pyside6' ('qt6' package).

'pip install autoscroll pyside6'

By default, the icon is disabled, to enable it pass '--icon-enable'.

You can pass file contents as command line arguments using '@path/to/the/file' syntax.

Arguments in that case can be placed wherever - on one line, on several lines.

If you want to dynamically pass arguments without restarting the process you can use '--config' options for it.

Once you press '--buttons-start', you can scroll vertically or horizontally just by moving your mouse untill you press '--buttons-end'.

If '--buttons-hold' is set, the srolling ends once you release '--buttons-start'.

You can change arguments on runtime by enabling a config file, you can do so by passing '--config-enable'.

Once '--buttons-start' is pressed, the scroll thread starts looping.

Every loop consists of sleeping for an interval, then scrolling for either 0, 1, or -1 pixels on both axis towards the starting point.

Starting point is the point where '--buttons-start' was pressed.

Sleep interval is recalculated on every mouse move as such:

    100 / ('--scrolling-acceleration' * max(distance) + '--scrolling-speed')

If '--scrolling-acceleration' is not 0, the speed of scrolling will be faster

the farther away you are from the starting point.

If '--scrolling-acceleration' is 0, the speed of the scrolling will be constant.

options:
  -h, --help            show this help message and exit

scrolling:

  -ss, --scrolling-speed int
                        constant part of the scrolling speed
                        [default: 300]
  -sd, --scrolling-dead-area int
                        size of the square area aroung the starting point where scrolling will stop, in
                        pixels
                        [default: 50]
  -sa, --scrolling-acceleration int
                        dynamic part of the scrolling speed, depends on the distance from the point
                        where the scrolling started, can be set to 0
                        [default: 10]

buttons:

  -bh, --buttons-hold   if set, the scrolling will end once you release --buttons-start
  -bs, --buttons-start int
                        button that starts the scrolling
                        [default: 2]
  -be, --buttons-end int
                        button that ends the scrolling
                        [default: --buttons-start]

config:

  -ce, --config-enable  if set, arguments from the configuration file on --config-path will be loaded

                        path to the configuration file

  -ci, --config-interval int
                        how often the config file should be checked for changes, in seconds

  -is, --icon-size int  size of the icon, in pixels
                        [default: 30]

  -df, --debug-file     if set, every time the config file is parsed, information will be printed to
                        stdout

  -ds, --debug-scroll   if set, scroll info will be printed to stdout
  -di, --debug-initial  if set, startup configuration will be printed to stdout
