## Gettting Started

The Bots standard commands are in ```commands.sh``` file. You must not add your commands to 'commands.sh', instead place them in ```mycommands.sh```,  there you also find examples how to process messages and send out text. See [Best practices](5_practice.md) for more information.

Once you're done with editing 'mycommands.sh' 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

#### sending messages
To send messages use the ```send_xxx_message``` functions.

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>"
```

To forward messages use the ```forward``` function:
```bash
forward "${CHAT[ID]}" "from_chat_id" "message_id"
```

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_message
In addition there is a universal send_massage function which can output any type of message.
This function is used to process output from external scrips like interactive chats or background jobs.  
**For safety and performance reasons I recommend to use send_xxxx_message functions above for sending messages**
```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"
```
More examples  boutsend_message strings can be found in [Advanced Usage](3_advanced.md#Interactive-Chats)


#### Send files, locations, keyboards.
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" ]' # note the simgle quotes!
send_keyboard "${CHAT[ID]}" "Text that will appear in chat?" "[ \\"Yep\\" , \\"No\\" ]" # within double quotes you must excape the inside double quots
```
To send locations use the ```send_location``` function:
```bash
send_location "${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"
```
