How can I extract the custom argument from a /invite command in Ruby, send a tailored reply, and log the command in a text file? Example:
case message.text
when /^\/adduser\s+(\S+)$/
username = $1
bot.api.send_message(chat_id: message.chat.id, text: "Processing #{username}")
File.open('cmd_log.txt', 'a') { |file| file.puts "/adduser #{username}" }
end
In my own experience with Telegram bots in Ruby, I found that segregating command parsing and file handling into distinct methods really improves maintainability. I created a dedicated method for sanitizing and validating incoming arguments which minimized potential errors. Additionally, I implemented my own logger class that not only writes to a file but also sends alerts in case of write failures. This modular approach allowed me to quickly isolate issues and made it easier to extend functionality for additional commands without cluttering the main message handling code.
hey jack81, your code works fine but i suggest wrapping the file write with a begin/rescue block to catch any errors. also, double-check for extra spaces in the regex for more robustness. cheers!
I have worked with similar functionality in my Ruby Telegram Bot implementation. In my project, I moved towards using Ruby’s Logger class to handle the logging part because it automatically adds timestamps and can easily rotate logs for long-term maintenance. I also made sure to validate and sanitize the command arguments to make sure there is no unexpected input. Furthermore, wrapping the send_message API call in a rescue block helped me debug network errors and reduced crashes, ensuring the bot remains stable even when unexpected issues arise.
Working on a Telegram bot project for my community, I encountered similar challenges when extracting custom arguments from commands. I remember that while your snippet works great, sometimes input arguments would accidentally include trailing spaces or even unintentional extra characters. I ended up combining regex validation with a pre-cleanup step to remove whitespace and ensure consistency. Additionally, I delegated logging to a separate thread to prevent slowdowns during high usage, which helped keep responses prompt while still maintaining a reliable audit trail of incoming commands.
hey jack81, try using .strip on the argument to avoid extra spaces. i swapped to a logging gem in my bot for smooth log rotation and a better error catch. hope it help, cheers!
