### Install bashbot
## Install bashbot
1. Go to the directory you want to install bashbot, e.g.
- your $HOME directory (install and run with your user-ID)
@ -87,355 +28,22 @@ git clone --recursive https://github.com/topkecleon/telegram-bot-bash
3. Change to directory ```telegram-bot.bash```, run ```./bashbot.sh init``` and follow the instructions. At this stage you are asked for your Bots token given by botfather.
## Creating your own Bot
All Commands for the Bot are in the ```commands.sh``` file (this should ease upgrades of the bot core). Here you find some examples how to process messages and send out text.
Once you're done editing start the Bot with ```./bashbot.sh start```.
If some thing doesn't work as it should, debug with ```bash -x bashbot.sh```. To stop the Bot run ```./bashbot.sh kill```
To use the functions provided in this script in other scripts simply source bashbot: ```source bashbot.sh```
Have FUN!

### Usage of bashbot functions
#### send_message
To send messages use the ```send_message``` function:
```bash
send_message "${CHAT[ID]}" "lol"
```
To send html or markdown put the following strings before the text, depending on the parsing mode you want to enable:
```bash
send_message "${CHAT[ID]}" "markdown_parse_mode lol *bold*"
```
```bash
send_message "${CHAT[ID]}" "html_parse_mode lol <b>bold</b>"
```
This function also allows a third parameter that disables additional function parsing (for safety use this when reprinting user input):
```bash
send_message "${CHAT[ID]}" "lol" "safe"
```
To forward messages use the ```forward``` function:
```bash
forward "${CHAT[ID]}" "from_chat_id" "message_id"
```
#### For safety and performance reasoms I recommend to use send_xxxx_message direct and not the universal send_message function.
To send regular text without any markdown use:
```bash
send_text_message "${CHAT[ID]}" "lol"
```
To send text with markdown:
```bash
send_markdown_message "${CHAT[ID]}" "lol *bold*"
```
To send text with html:
```bash
send_html_message "${CHAT[ID]}" "lol <b>bold</b>"
```
If your Bot is Admin in a Chat you can delete every message, if not you can delete only your messages.
To delete a message with a known ${MESSAGE[ID]} you can simple use:
```bash
delete_message "${CHAT[ID]}" "${MESSAGE[ID]}"
```
#### Send files, location etc.
To send images, videos, voice files, photos etc. use the ```send_photo``` function (remember to change the safety Regex @ line 14 of command.sh to allow sending files only from certain directories):
```bash
send_file "${CHAT[ID]}" "/home/user/doge.jpg" "Lool"
```
To send custom keyboards use the ```send_keyboard``` function:
```bash
send_keyboard "${CHAT[ID]}" "Text that will appear in chat?" "Yep" "No"
```
To send locations use the ```send_location``` function:
```bash
send_location "${CHAT[ID]}" "Latitude" "Longitude"
```
To send venues use the ```send_venue``` function:
```bash
send_venue "${CHAT[ID]}" "Latitude" "Longitude" "Title" "Address" "optional foursquare id"
```
To send a chat action use the ```send_action``` function.
Allowed values: typing for text messages, upload_photo for photos, record_video or upload_video for videos, record_audio or upload_audio for audio files, upload_document for general files, find_location for locations.
```bash
send_action "${CHAT[ID]}" "action"
```
#### Interactive Chats
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:
```bash
echo "Text that will appear in chat? mykeyboardstartshere \"Yep, sure\" \"No, highly unlikely\""
```
Same goes for files:
```bash
echo "Text that will appear in chat? myfilelocationstartshere /home/user/doge.jpg"
```
And locations:
```bash
echo "Text that will appear in chat. mylatstartshere 45 mylongstartshere 45"
```
And venues:
```bash
echo "Text that will appear in chat. mylatstartshere 45 mylongstartshere 45 mytitlestartshere my home myaddressstartshere Diagon Alley N. 37"
```
You can combine them:
```bash
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.
To insert a linebreak in your message you can insert ```mynewlinestartshere``` in your echo command:
```bash
echo "Text that will appear in one message mynewlinestartshere with this text on a new line"
```
Note: Interactive Chats run independent from main bot and continue running until your script exits or you /cancel if from your Bot.
#### Background Jobs
A background job is similar to an interactive chat, but runs in the background and does only output massages instead of processing input from the user. In contrast to interactive chats it's possible to run multiple background jobs. To create a background job write a script or edit the notify script and use the funtion ```background``` to start it:
```bash
background "./notify" "jobname"
```
All output of the script will be sent to the user or chat. To stop a background job use:
```bash
killback "jobname"
```
You can also suspend and resume the last running background jobs from outside bashbot, e.g. in your startup schripts:
```bash
./bashbot.sh suspendback
./bashbot.sh resumeback
```
If you want to kill all background jobs permantly run:
```bash
./bashbot.sh killback
```
Note: Background Jobs run independent from main bot and continue running until your script exits or you stop if from your Bot. Backgound Jobs will continue running if your Bot is stoped (kill)!.
#### Inline queries
The following commands allows users to interact with your bot via *inline queries*.
In order to enable **inline mode**, send `/setinline` command to [@BotFather](https://telegram.me/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*:
```bash
answer_inline_query "$iQUERY_ID" "article" "Title of the result" "Content of the message to be sent"
```
To send photos in jpeg format and less than 5MB, from a website through an *inline query*:
```bash
answer_inline_query "$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*:
```bash
answer_inline_query "$iQUERY_ID" "gif" "gif url"
```
To send mpeg4 gifs from a website (less than 1MB) through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "mpeg4_gif" "mpeg4 gif url"
```
To send videos from a website through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "video" "valid video url" "Select one mime type: text/html or video/mp4" "URL of the thumbnail" "Title for the result"
```
To send photos stored in Telegram servers through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "cached_photo" "identifier for the photo"
```
To send gifs stored in Telegram servers through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "cached_gif" "identifier for the gif"
```
To send mpeg4 gifs stored in Telegram servers through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "cached_mpeg4_gif" "identifier for the gif"
```
To send stickers through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "cached_sticker" "identifier for the sticker"
```
## Managing your Bot
#### Note: running bashbot as root is highly danger and not recommended. See Expert use below.
### Start / Stop
Start or Stop your Bot use the following commands:
```bash
./bashbot.sh start
```
```bash
./bashbot.sh kill
```
### 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!"
```
## Handling UTF-8 character sets
### Setting up your Environment
In general ```bash``` and ```GNU``` utitities are UTF-8 aware, but you have to setup your environment
and your scripts accordingly:
1. Your Terminal and Editor must support UTF-8:
Set Terminal and Editor locale to UTF-8, eg. in ```Settings/Configuration``` select UTF-8 (Unicode) as Charset.
2. Set ```Shell``` environment to UTF-8 in your ```.profile``` and your scripts. The usual settings are:
```bash
export 'LC_ALL=C.UTF-8'
export 'LANG=C.UTF-8'
export 'LANGUAGE=C.UTF-8'
```
If you use other languages, eg. german or US english, change the shell settings to:
```bash
export 'LC_ALL=de_DE.UTF-8'
export 'LANG=de_DE.UTF-8'
export 'LANGUAGE=de_DE.UTF-8'
```
```bash
export 'LC_ALL=en_US.UTF-8'
export 'LANG=de_en_US.UTF-8'
export 'LANGUAGE=den_US.UTF-8'
```
3. make shure your bot scripts use the correct settings, eg. include the lines above at the beginning of your scripts
To display all availible locales on your system run ```locale -a | more```. [Gentoo Wiki](https://wiki.gentoo.org/wiki/UTF-8)
### UTF-8 in Telegram
```UTF-8``` is a variable length encoding of Unicode. UTF-8 is recommended as the default encoding in JSON, XML and HTML, also Telegram make use of it.
The first 128 characters are regular ASCII, so it's a superset of and compatible with ASCII environments. The next 1,920 characters need
two bytes for encoding and covers almost all ```Latin``` alphabets, also ```Greek```, ```Cyrillic```,
```Hebrew```, ```Arabic``` and more. See [Wikipedia](https://en.wikipedia.org/wiki/UTF-8) for more deatils.
Telegram send Messages with all characters not fitting in one byte (256 bit) escaped as sequences of ```\uxxxx``` to be regular one byte ASCII (incl. iso-xxx-x), e.g. Emoticons and Arabic characters.
E.g. the Emoticons ``` 😁 😘 ❤️ 😊 👍 ``` are encoded as:
```
\uD83D\uDE01 \uD83D\uDE18 \u2764\uFE0F \uD83D\uDE0A \uD83D\uDC4D
```
'\uXXXX' and '\UXXXXXXXX' escaped endocings are supported by zsh, bash, ksh93, mksh and FreeBSD sh, GNU 'printf' and GNU 'echo -e', see [this Stackexchange Answer](https://unix.stackexchange.com/questions/252286/how-to-convert-an-emoticon-specified-by-a-uxxxxx-code-to-utf-8/252295#252295) for more information.
## Expert Use
Bashbot is desingned to run manually by the user who installed it. Nevertheless it's possible to run it by an other user-ID, as a system service or sceduled from cron. This is onyl recommended for experiend linux users.
### Run as other user or system service
Running bashbot as an other user is only possible with sudo rigths.
Setup the environment for the user you want to run bashbot and enter desired username, e.g. nobody :
```bash
sudo ./bashbot.sh init
```
Edit the file ```bashbot.rc``` and edit the following lines to fit your configuration:
```bash
#######################
# Configuration Section
# edit the next line to fit the user you want to run bashbot, e.g. nobody:
runas="nobody"
# uncomment one of the following lines
# runcmd="su $runas -s /bin/bash -c " # runasuser with su
# runcmd="runuser $runas -s /bin/bash -c " # runasuser with runuser
# edit the values of the following lines to fit your config:
start="/usr/local/telegram-bot-bash/bashbot.sh" # location of your bashbot.sh script
name='' # your bot name as given to botfather, e.g. mysomething_bot
# END Configuration
#######################
```
From now on always use bashbot.rc to start/stop your bot:
```bash
sudo ./bashbot.rc start
```
Type ```ps -ef | grep bashbot``` to verify your Bot is running as the desired user.
If you started bashbot by bashbot.rc you must use bashbot.rc also to manage your Bot! The following commands are availible:
```bash
sudo ./bashbot.rc start
sudo ./bashbot.rc stop
sudo ./bashbot.rc status
sudo ./bashbot.rc suspendback
sudo ./bashbot.rc resumeback
sudo ./bashbot.rc killback
```
To change back the environment to your user-ID run ```sudo ./bashbot.sh init``` again and enter your user name.
To use bashbot as a system servive include a working ```bashbot.rc``` in your init system (systemd, /etc/init.d).
### Scedule bashbot from Cron
An example crontab is provided in ```bashbot.cron```.
- If you are running bashbot with your user-ID, copy the examples lines to your crontab and remove username ```nobody```.
- if you run bashbot as an other user or a system service edit ```bashbot.cron``` to fit your needs and replace username```nobody``` with the username you want to run bashbot. copy the modified file to ```/etc/cron.d/bashbot```

forward "${CHAT[ID]}" "from_chat_id" "message_id"
```
#### For safety and performance reasoms I recommend to use send_xxxx_message direct and not the universal send_message function.
To send regular text without any markdown use:
```bash
send_text_message "${CHAT[ID]}" "lol"
```
To send text with markdown:
```bash
send_markdown_message "${CHAT[ID]}" "lol *bold*"
```
To send text with html:
```bash
send_html_message "${CHAT[ID]}" "lol <b>bold</b>"
```
If your Bot is Admin in a Chat you can delete every message, if not you can delete only your messages.
To delete a message with a known ${MESSAGE[ID]} you can simple use:
```bash
delete_message "${CHAT[ID]}" "${MESSAGE[ID]}"
```
#### Send files, location etc.
To send images, videos, voice files, photos etc. use the ```send_photo``` function (remember to change the safety Regex @ line 14 of command.sh to allow sending files only from certain directories):
```bash
send_file "${CHAT[ID]}" "/home/user/doge.jpg" "Lool"
```
To send custom keyboards use the ```send_keyboard``` function:
```bash
send_keyboard "${CHAT[ID]}" "Text that will appear in chat?" "Yep" "No"
```
To send locations use the ```send_location``` function:
```bash
send_location "${CHAT[ID]}" "Latitude" "Longitude"
```
To send venues use the ```send_venue``` function:
```bash
send_venue "${CHAT[ID]}" "Latitude" "Longitude" "Title" "Address" "optional foursquare id"
```
To send a chat action use the ```send_action``` function.
Allowed values: typing for text messages, upload_photo for photos, record_video or upload_video for videos, record_audio or upload_audio for audio files, upload_document for general files, find_location for locations.
```bash
send_action "${CHAT[ID]}" "action"
```

## Advanced Features
### Interactive Chats
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:
```bash
echo "Text that will appear in chat? mykeyboardstartshere \"Yep, sure\" \"No, highly unlikely\""
```
Same goes for files:
```bash
echo "Text that will appear in chat? myfilelocationstartshere /home/user/doge.jpg"
```
And locations:
```bash
echo "Text that will appear in chat. mylatstartshere 45 mylongstartshere 45"
```
And venues:
```bash
echo "Text that will appear in chat. mylatstartshere 45 mylongstartshere 45 mytitlestartshere my home myaddressstartshere Diagon Alley N. 37"
```
You can combine them:
```bash
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.
To insert a linebreak in your message you can insert ```mynewlinestartshere``` in your echo command:
```bash
echo "Text that will appear in one message mynewlinestartshere with this text on a new line"
```
Note: Interactive Chats run independent from main bot and continue running until your script exits or you /cancel if from your Bot.
### Background Jobs
A background job is similar to an interactive chat, but runs in the background and does only output massages instead of processing input from the user. In contrast to interactive chats it's possible to run multiple background jobs. To create a background job write a script or edit the notify script and use the funtion ```background``` to start it:
```bash
background "./notify" "jobname"
```
All output of the script will be sent to the user or chat. To stop a background job use:
```bash
killback "jobname"
```
You can also suspend and resume the last running background jobs from outside bashbot, e.g. in your startup schripts:
```bash
./bashbot.sh suspendback
./bashbot.sh resumeback
```
If you want to kill all background jobs permantly run:
```bash
./bashbot.sh killback
```
Note: Background Jobs run independent from main bot and continue running until your script exits or you stop if from your Bot. Backgound Jobs will continue running if your Bot is stoped (kill)!.
### Inline queries
The following commands allows users to interact with your bot via *inline queries*.
In order to enable **inline mode**, send `/setinline` command to [@BotFather](https://telegram.me/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*:
```bash
answer_inline_query "$iQUERY_ID" "article" "Title of the result" "Content of the message to be sent"
```
To send photos in jpeg format and less than 5MB, from a website through an *inline query*:
```bash
answer_inline_query "$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*:
```bash
answer_inline_query "$iQUERY_ID" "gif" "gif url"
```
To send mpeg4 gifs from a website (less than 1MB) through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "mpeg4_gif" "mpeg4 gif url"
```
To send videos from a website through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "video" "valid video url" "Select one mime type: text/html or video/mp4" "URL of the thumbnail" "Title for the result"
```
To send photos stored in Telegram servers through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "cached_photo" "identifier for the photo"
```
To send gifs stored in Telegram servers through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "cached_gif" "identifier for the gif"
```
To send mpeg4 gifs stored in Telegram servers through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "cached_mpeg4_gif" "identifier for the gif"
```
To send stickers through an *inline query*:
```bash
answer_inline_query "$iQUERY_ID" "cached_sticker" "identifier for the sticker"
```

## Expert Use
### Handling UTF-8 character sets
#### Setting up your Environment
In general ```bash``` and ```GNU``` utitities are UTF-8 aware, but you have to setup your environment
and your scripts accordingly:
1. Your Terminal and Editor must support UTF-8:
Set Terminal and Editor locale to UTF-8, eg. in ```Settings/Configuration``` select UTF-8 (Unicode) as Charset.
2. Set ```Shell``` environment to UTF-8 in your ```.profile``` and your scripts. The usual settings are:
```bash
export 'LC_ALL=C.UTF-8'
export 'LANG=C.UTF-8'
export 'LANGUAGE=C.UTF-8'
```
If you use other languages, eg. german or US english, change the shell settings to:
```bash
export 'LC_ALL=de_DE.UTF-8'
export 'LANG=de_DE.UTF-8'
export 'LANGUAGE=de_DE.UTF-8'
```
```bash
export 'LC_ALL=en_US.UTF-8'
export 'LANG=de_en_US.UTF-8'
export 'LANGUAGE=den_US.UTF-8'
```
3. make shure your bot scripts use the correct settings, eg. include the lines above at the beginning of your scripts
To display all availible locales on your system run ```locale -a | more```. [Gentoo Wiki](https://wiki.gentoo.org/wiki/UTF-8)
#### UTF-8 in Telegram
```UTF-8``` is a variable length encoding of Unicode. UTF-8 is recommended as the default encoding in JSON, XML and HTML, also Telegram make use of it.
The first 128 characters are regular ASCII, so it's a superset of and compatible with ASCII environments. The next 1,920 characters need
two bytes for encoding and covers almost all ```Latin``` alphabets, also ```Greek```, ```Cyrillic```,
```Hebrew```, ```Arabic``` and more. See [Wikipedia](https://en.wikipedia.org/wiki/UTF-8) for more deatils.
Telegram send Messages with all characters not fitting in one byte (256 bit) escaped as sequences of ```\uxxxx``` to be regular one byte ASCII (incl. iso-xxx-x), e.g. Emoticons and Arabic characters.
E.g. the Emoticons ``` 😁 😘 ❤️ 😊 👍 ``` are encoded as:
```
\uD83D\uDE01 \uD83D\uDE18 \u2764\uFE0F \uD83D\uDE0A \uD83D\uDC4D
```
'\uXXXX' and '\UXXXXXXXX' escaped endocings are supported by zsh, bash, ksh93, mksh and FreeBSD sh, GNU 'printf' and GNU 'echo -e', see [this Stackexchange Answer](https://unix.stackexchange.com/questions/252286/how-to-convert-an-emoticon-specified-by-a-uxxxxx-code-to-utf-8/252295#252295) for more information.
### Run as other user or system service
Bashbot is desingned to run manually by the user who installed it. Nevertheless it's possible to run it by an other user-ID, as a system service or sceduled from cron. This is onyl recommended for experiend linux users.
####Running bashbot as an other user is only possible with sudo rigths.
Setup the environment for the user you want to run bashbot and enter desired username, e.g. nobody :
```bash
sudo ./bashbot.sh init
```
Edit the file ```bashbot.rc``` and edit the following lines to fit your configuration:
```bash
#######################
# Configuration Section
# edit the next line to fit the user you want to run bashbot, e.g. nobody:
runas="nobody"
# uncomment one of the following lines
# runcmd="su $runas -s /bin/bash -c " # runasuser with su
# runcmd="runuser $runas -s /bin/bash -c " # runasuser with runuser
# edit the values of the following lines to fit your config:
start="/usr/local/telegram-bot-bash/bashbot.sh" # location of your bashbot.sh script
name='' # your bot name as given to botfather, e.g. mysomething_bot
# END Configuration
#######################
```
From now on always use bashbot.rc to start/stop your bot:
```bash
sudo ./bashbot.rc start
```
Type ```ps -ef | grep bashbot``` to verify your Bot is running as the desired user.
If you started bashbot by bashbot.rc you must use bashbot.rc also to manage your Bot! The following commands are availible:
```bash
sudo ./bashbot.rc start
sudo ./bashbot.rc stop
sudo ./bashbot.rc status
sudo ./bashbot.rc suspendback
sudo ./bashbot.rc resumeback
sudo ./bashbot.rc killback
```
To change back the environment to your user-ID run ```sudo ./bashbot.sh init``` again and enter your user name.
To use bashbot as a system servive include a working ```bashbot.rc``` in your init system (systemd, /etc/init.d).
### Scedule bashbot from Cron
An example crontab is provided in ```bashbot.cron```.
- If you are running bashbot with your user-ID, copy the examples lines to your crontab and remove username ```nobody```.
- if you run bashbot as an other user or a system service edit ```bashbot.cron``` to fit your needs and replace username```nobody``` with the username you want to run bashbot. copy the modified file to ```/etc/cron.d/bashbot```
