Simulate mouse movement in Ubuntu - command-line

Question

Problem
Am looking to automatically move the mouse cursor and simulate mouse button clicks from the command-line using an external script. Am not looking to:
Record mouse movement and playback (e.g., xnee, xmacro)
Instantly move the mouse from one location to another (e.g., xdotool, Python's warp_pointer)
Ideal Solution
What I'd like to do is the following:
Edit a simple script file (e.g., mouse-script.txt).
Add a list of coordinates, movement speeds, delays, and button clicks. For example:
(x, y, rate) = (500, 500, 50)
sleep = 5
click = left
Run the script: xsim < mouse-script.txt.
Question
How do you automate mouse movement so that it transitions from its current location to another spot on the screen, at a specific velocity? For example:
xdotool mousemove 500 500 --rate 50
The --rate 50 doesn't exist with xdotool.

Answer 1

on newer versions of Ubuntu (14.04+), you can use Autopilot, a UI testing tool for Ubuntu. It is made for creating and running user interface tests, but can also be used for basic GUI automation tasks.
to install:
$ sudo apt-get install python3-autopilot
an example script (Python3) to automate mouse movement:
#!/usr/bin/env python3
from autopilot.input import Mouse
mouse = Mouse.create()
mouse.move(100, 50)
mouse.click()
You would run this just like any other Python3 script. Watch your mouse pointer move!

Download xaut for Python
Follow the README instructions
Run:
sudo apt-get install swig x11proto-xext-dev libx11-dev libxtst-dev
cd /usr/local/src
tar zxf xaut-0.2.0.tar.gz
./configure
Edit src/Makefile
Change the CFLAGS line as follows:
CFLAGS = -Wall -fPIC -fno-stack-protector
Run:
make
Copy /usr/local/src/xaut-0.2.0/python/build/lib/* to a new directory.
Change to that new directory.
Copy and paste the following script into mm.py:
import xaut
mouse = xaut.mouse()
delay mouse.move_delay( 100 )
mouse.move( 500, 500 )
Run the script:
python mm.py
