• Python 3
• MySQL

Clone repository

git clone https://github.com/30mb1/BTC-change-bot.git

Create virtual environment and install requirements.

virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt

Create database for bot

mysql -u <user> -p < database.sql

Bot is still in development.

• Bot store all temporary information in object called user_data - dictionary, unique for every user. Information about messages state(for example page in list of orders and etc.), choosed language and other data.

• Bot use this library for work.

• Bot supports localization via gettext. All texts that bot use are stored in texts.py file. To create new localization file, generate .po file using texts.py, moderate it and compile. Then place compiled .mo file in an appropriate folder in /locale. Insert translation function in utils/decorators.py in LANGS variable, so @info decorator would provide it to all bot functions. (function for choosing language is not created yet)

• When inline button is pressed, bot get special callback update, which contains callback_data. It usually has next structure:

  ​ (level1) (level2) (additional info)

  App use this data for routing. At first, high level router send update(user's message) to section depending on level1 value; then, next section-router sends update to appropriate function-handler using level2. Every section has its own router in file, named same as directory.

• create function for choosing language and create appropriate interface element
• develop trade process - at the moment nothing happens when pressing button 'start bargain'
• complete 'create new bargain' process
• develop mechanism of getting prices from exchanges - values are hardcoded now
• connect nodes to bot - there is no real work with currencies at the moment. Need to create wallets for clients and develop exchange mechanism
