 3 | # A simple AHK script to keep Google Colab alive:
 4 | 
 5 | This script uses AutoHotKey, an automation scripting language and tool, to emulate human interface device interactions on Google Colab notebook to avoid runtime inactivity timeouts.
 6 | 
 7 | > **Note:** this works only on Windows OS!
 8 | 
 9 | Read the [medium article](https://medium.com/analytics-vidhya/how-to-save-google-colab-notebooks-from-runtime-timeouts-4aa133375a7e) for more information. 
10 | 
11 | ## Usage
12 | 
13 | ##### Executable Binary (No dependencies) : 
14 | > - Download the .exe from the [releases](https://github.com/sour4bh/stop-cursing-colab/releases) section. 
15 | > - Just double-click the executable `colab_keep_alive.exe`
16 | > - Enter the file name of the colab `<filename.ipynb>` 
17 | > - Set the interval for HID interactions (in mins)
18 | > - Done. 
19 | 
20 | ##### CIY using Authotkey :
21 | > - Install [AutoHotKey](https://www.autohotkey.com/download/ahk-install.exe)
22 | > - Double-click `colab_keep_alive.ahk` to run. [ To compile, right click > compile ]
23 | > - Enter the file name of the colab `<filename.ipynb>` 
24 | > - Set the interval for HID interactions (in mins)
25 | > - Done. 
26 | 
27 | ## Troubleshoot
28 | - The title of the window should be `<filename.ipynb> - Colaboratory - Google Chrome`
29 | - If there are multiple tabs in the Chrome Window, make sure colab notebook is the active one. 
30 | - Make sure power sleep/hibernate timeout is greater than script's interval 🙃
