Inline Telegram bot for generating directed graphs

This bot is live at https://t.me/graphviz_bot

Requirements

• PHP >= 5
• Mysql >= 5.5
• Graphviz cli installed

Installing

1. Clone the repo in a non-web-accesible place
2. Add a symbolic link in your public_html or html folder pointing to the web folder of this project.
3. Give permissions on the images folder to allow apache write files and also allow them to be accesible from the web.
4. Edit the config.php file and provide your bot token, web-accesible path to the bot, and mysql credentials
5. Edit the web/config.php and provide the unix path to the config.php from last point
6. Create a symbolic link from the web/bot folder to a web/botBOTNUMBER. This is not mandatory, but your webhook path shouln't be easy to spot. If you do not care, modify .htaccesss file to allow accesses to the web/bot directory.
7. Setup the webhook pointing to the symbolic link just created.

TODO

• Improve start method
