InlineLaTeX

A LaTeX-producing inline bot for Telegram Messenger.

The bot is online. Try by querying @inlinetexbot. If all goes right, you'll be seeing something like this: The bot is offline. This is what it'll look like if you run your own version: .

Notes on the Source

InlineLaTex relies on the async version of the telepot libraries. See that module's documentation for more details. Because of my use of async/await syntax, InlineLaTex requires Python 3.5.

Running Your Own

To run this script on your own, you will need a web server to host any generated LaTeX-carrying images. This is necessary: as of February 22, 2016, inline bots cannot directly send images over Telegram. However, they may send image URLs. A (possibly different) computer will need to run the InlineLaTeX script. This computer will need a working version of Python 3.5, a LaTeX distribution with the pdflatex tool installed, and the gs (GhostScript) utility for converting the output PDF.

1. Register a Telegram bot at Botfather. Indicate that your bot will respond to inline queries. Take note of your access token.
2. Paste your access token, as well as your credentials into the sample_config.json file. Rename this file to config.json (or point the corresponding variable to your file in config_reader.py)
3. Run the script: python3.5 inlinetexbot.py.
4. To enable more detailed logging, change log-levels to DEBUG in the inlinetex_loggers.py file.
