Usage

To send messages use the send_message function:

send_message "${CHAT[ID]}" "lol"

To send html or markdown put the following strings before the text, depending on the parsing mode you want to enable:

send_message "${CHAT[ID]}" "markdown_parse_mode lol *bold*"

send_message "${CHAT[ID]}" "html_parse_mode lol <b>bold</b>"

This function also allows a third parameter that disables additional function parsing (for safety use this when reprinting user input):

send_message "${CHAT[ID]}" "lol" "safe"

To send images, videos, voice files, photos ecc use the send_photo function (remember to change the safety Regex @ line 14 of command.sh to allow sending files only from certain directories):

send_file "${CHAT[ID]}" "/home/user/doge.jpg" "Lool"

To send custom keyboards use the send_keyboard function:

send_keyboard "${CHAT[ID]}" "Text that will appear in chat?" "Yep" "No"

To send locations use the send_location function:

send_location "${CHAT[ID]}" "Latitude" "Longitude"

To send venues use the send_venue function:

send_venue "${CHAT[ID]}" "Latitude" "Longitude" "Title" "Address" "optional foursquare id"

To forward messages use the forward function:

forward "${CHAT[ID]}" "from_chat_id" "message_id"

To send a chat action use the send_action function. Allowed values: typing for text messages, upload_photo for photos, record_video or upload_video for videos, record_audio or upload_audio for audio files, upload_document for general files, find_location for locations.

send_action "${CHAT[ID]}" "action"

To create interactive chats, write (or edit the question script) a normal bash (or C or python) script, chmod +x it and then change the argument of the startproc function to match the command you usually use to start the script. The text that the script will output will be sent in real time to the user, and all user input will be sent to the script (as long as it's running or until the user kills it with /cancel). To open up a keyboard in an interactive script, print out the keyboard layout in the following way:

echo "Text that will appear in chat? mykeyboardstartshere \"Yep, sure\" \"No, highly unlikely\""

Same goes for files:

echo "Text that will appear in chat? myfilelocationstartshere /home/user/doge.jpg"

And locations:

echo "Text that will appear in chat. mylatstartshere 45 mylongstartshere 45"

And venues:

echo "Text that will appear in chat. mylatstartshere 45 mylongstartshere 45 mytitlestartshere my home myaddressstartshere Diagon Alley N. 37"

You can combine them:

echo "Text that will appear in chat? mykeyboardstartshere \"Yep, sure\" \"No, highly unlikely\" myfilelocationstartshere /home/user/doge.jpg mylatstartshere 45 mylongstartshere 45"

Please note that you can either send a location or a venue, not both. To send a venue add the mytitlestartshere and the myaddressstartshere keywords.

The following commands allows users to interact with your bot via inline queries. In order to enable inline mode, send /setinline command to @BotFather and provide the placeholder text that the user will see in the input field after typing your bot’s name. Also, edit line 12 from commands.sh putting a "1". Note that you can't modify the first two parameters of the function answer_inline_query, only the ones after them.

To send messsages or links through an inline query:

answer_inline_query "$iQUERY_ID" "article" "Title of the result" "Content of the message to be sent"

To send photos in jpeg format and less than 5MB, from a website through an inline query:

answer_inline_query "$iQUERY_ID" "photo" "A valid URL of the photo" "URL of the thumbnail"

To send standard gifs from a website (less than 1MB) through an inline query:

answer_inline_query "$iQUERY_ID" "gif" "gif url"

To send mpeg4 gifs from a website (less than 1MB) through an inline query:

answer_inline_query "$iQUERY_ID" "mpeg4_gif" "mpeg4 gif url"

To send videos from a website through an inline query:

answer_inline_query "$iQUERY_ID" "video" "valid video url" "Select one mime type: text/html or video/mp4" "URL of the thumbnail" "Title for the result"

To send photos stored in Telegram servers through an inline query:

answer_inline_query "$iQUERY_ID" "cached_photo" "identifier for the photo"

To send gifs stored in Telegram servers through an inline query:

answer_inline_query "$iQUERY_ID" "cached_gif" "identifier for the gif"

To send mpeg4 gifs stored in Telegram servers through an inline query:

answer_inline_query "$iQUERY_ID" "cached_mpeg4_gif" "identifier for the gif"

To send stickers through an inline query:

answer_inline_query "$iQUERY_ID" "cached_sticker" "identifier for the sticker"

To modify the responses to commands edit the commands.sh file (this should ease upgrades of the bot core).

Once you're done editing start the bot with ./bashbot.sh start. If you want to do some more changes make them and then rerun the same command. To stop the bot run ./bashbot.sh kill. If some thing doesn't work as it should, debug with bash -x bashbot.sh.

To use the functions provided in this script in other scripts simply source bashbot: source bashbot.sh

User count

To count the total number of users that ever used the bot run the following command:

bash bashbot.sh count

Sending broadcasts to all users

To send a broadcast to all of users that ever used the bot run the following command:

bash bashbot.sh broadcast "Hey! I just wanted to let you know that the bot's been updated!"

That's it!
