#### [Home](../README.md)
## Getting Started

The Bots standard commands are in the commands dispatcher ```commands.sh```, Do not edit this file! Add your commands and functions to ```mycommands.sh```. In 'mycommands.sh.dist' you find examples how to add own commands and overwrite existing ones. See [Best practices](5_practice.md) for more information.

Once you're done with editing start the Bot with ```./bashbot.sh start```.  To stop the Bot run ```./bashbot.sh stop```

If something doesn't work as expected, debug with ```./bashbot.sh startbot DEBUG &```, where DEBUG can be 'debug', 'xdebug' or 'xdebugx'.
See [Bashbot Development](7_develop.md) for more information.

To use the functions provided in this script in other scripts simply source bashbot: ```source bashbot.sh source```. see [Expert Use](8_expert.md#Expert-use)

Have FUN!

e.g. if a new user joins a chat MESSAGE is set to "/_new_chat_user".

### Send Message Results

BOTSENT is set on every send_xxx action and only valid until next send action. For more on message results see.  
[Advanced Usage](3_advanced.md)

* ```$BOTSENT```: This array contains the parsed results from the last transmission to telegram.
    * ```${BOTSENT[OK]}```: contains the string ```true```: after a successful transmission
    * ```${BOTSENT[ID]}```: Message ID of sent message, image, file etc., if OK is true


## 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"
```
**See also [Interactive chats](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 single quotes!
send_keyboard "${CHAT[ID]}" "Text that will appear in chat?" "[ \\"Yep\\" , \\"No\\" ]" # within double quotes you must escape the inside double quots
```
To send locations use the ```send_location``` function:
```bash
send_location "${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"
```
