The original game can be found at https://orteil.dashnet.org/cookieclicker/

This mirror for, errrr, like, educational purpose, either to download for your own offline education or to be played online from https://ozh.github.io/cookieclicker/ if you cannot "educate" yourself on the original URL

If the original game updates, here is how you can update the mirror:

From the root,

• cd img/
• wget --convert-links -O index.html https://orteil.dashnet.org/cookieclicker/img/
• grep -v PARENTDIR index.html | grep '\[IMG' | grep -Po 'a href="\K.*?(?=")' | sed 's/\?.*//' > _imglist.txt
• wget -N -i _imglist.txt -B https://orteil.dashnet.org/cookieclicker/img/

Similarly, from the root :

• cd snd/
• wget --convert-links -O index.html https://orteil.dashnet.org/cookieclicker/snd/
• grep -v PARENTDIR index.html | grep '\[SND' | grep -Po 'a href="\K.*?(?=")' | sed 's/\?.*//' > _sndlist.txt
• wget -N -i _sndlist.txt -B https://orteil.dashnet.org/cookieclicker/snd/

Similarly, from the root :

• cd loc/
• wget --convert-links -O index.html https://orteil.dashnet.org/cookieclicker/loc/
• grep -v PARENTDIR index.html | grep '\[ ' | grep -Po 'a href="\K.*?(?=")' | sed 's/\?.*//' > _loclist.txt
• wget -N -i _loclist.txt -B https://orteil.dashnet.org/cookieclicker/loc/

From the root directory :

• Fetch the updated index.html file: wget -O index.html https://orteil.dashnet.org/cookieclicker/
• Fetch the updated style.css file: wget -O style.css https://orteil.dashnet.org/cookieclicker/style.css
• Fetch updated js files : wget -N -i _jslist.txt -B https://orteil.dashnet.org/cookieclicker/
• Scan index.html for any new <script src and also main.js for any new local javascript (eg Game.last.minigameUrl). If there are new scripts, update the _jslist.txt accordingly.
• In main.js there is a call to a remote script we need to modify:
  • Look for ajax('/patreon/grab.php' and replace it with ajax('grab.txt'
  • In the root: wget -O grab.txt https://orteil.dashnet.org/patreon/grab.php

If you happen to update, please make a pull request for others to benefit, thanks!
