## Customize bashbots environment
This section describe how you can customize bashbot to your needs by setting environment variables. 


### Change file locations
In standard setup bashbot is self containing, this means you can place 'telegram-bot-bash'  any location
and run it from there. All files - programm, config, data etc - will reside in 'telegram-bot-bash'.

If you want to have other locations for config, data etc,  define and export the following environment variables.
**Note: all specified directories and files must exist or running 'bashbot.sh' will fail.**

#### BASHBOT_ETC
Location of the files ```commands.sh```, ```mycommands.sh```, ```token```, ```botadmin```, ```botacl``` ...
```bash
  unset  BASHBOT_ETC     # keep in telegram-bot-bash (default)
  export BASHBOT_ETC ""  # keep in telegram-bot-bash

  export BASHBOT_ETC "/etc/bashbot"  # unix like config location

  export BASHBOT_ETC "/etc/bashbot/bot1"  # multibot configuration bot 1
  export BASHBOT_ETC "/etc/bashbot/bot2"  # multibot configuration bot 2
```

 e.g. /etc/bashbot

#### BASHBOT_VAR
Location of runtime data ```data-bot-bash```, ```count``` 
```bash
  unset  BASHBOT_VAR     # keep in telegram-bot-bash (default)
  export BASHBOT_VAR ""  # keep in telegram-bot-bash

  export BASHBOT_VAR "/var/spool/bashbot"  # unix like config location

  export BASHBOT_VAR "/var/spool/bashbot/bot1"  # multibot configuration bot 1
  export BASHBOT_VAR "/var/spool/bashbot/bot2"  # multibot configuration bot 2
```

#### BASHBOT_JSONSH
Full path to JSON.sh script, default: './JSON.sh/JSON.sh', must end with '/JSON.sh'.
```bash
  unset  BASHBOT_JSONSH     # telegram-bot-bash/JSON.sh/JSON.sh (default)
  export BASHBOT_JSONSH ""  # telegram-bot-bash/JSON.sh/JSON.sh

  export BASHBOT_JSONSH "/usr/local/bin/JSON.sh"  # installed in /usr/local/bin

```

### Change config values

#### BASHBOT_URL
Uses given URL instead of offical telegram API URL, useful if you have your own telegram server or for testing.

```bash
  unset  BASHBOT_URL       # use Telegram URL https://api.telegram.org/bot<token> (default)

  export BASHBOT_URL ""    # use use Telegram https://api.telegram.org/bot<token>

  export BASHBOT_URL "https://my.url.com/bot" # use your URL https://my.url.com/bot<token>

```

#### BASHBOT_TOKEN

#### BASHBOT_WGET
Bashbot uses ```curl``` to communicate with telegram server. if ```curl``` is not availible ```wget``` is used.
If 'BASHBOT_WGET' is set to any value (not undefined or not empty) wget is used even is curl is availible.  
```bash
  unset  BASHBOT_WGET       # use curl (default)
  export BASHBOT_WGET ""    # use curl 

  export BASHBOT_WGET "yes" # use wget
  export BASHBOT_WGET "no"  # use wget!

```

#### BASHBOT_SLEEP
Instead of polling permanently or with a fixed delay, bashbot offers a simple adaptive polling.
If messages are recieved bashbot polls with no dealy. If no messages are availible bashbot add 100ms delay
for every poll until the maximum of BASHBOT_SLEEP ms.
```bash
  unset  BASHBOT_SLEEP       # 5000ms (default)
  export BASHBOT_SLEEP ""    # 5000ms 

  export BASHBOT_SLEEP "1000"     # 1s maximum sleep 
  export BASHBOT_SLEEP "10000"    # 10s maximum sleep
  export BASHBOT_SLEEP "1"        # values < 1000 disables sleep (not recommended) 
  
```

### Testet configs as of v.07 release
**Note: Environment variables are not stored, you must setup them before every call to bashbot.sh, e.g. from a script.**

#### simple Unix like config, for one bot. bashbot is installed in '/usr/local/telegram-bot-bash'
```bash
  # Note: all dirs and files must exist!
  export BASHBOT_ETC "/etc/bashbot"
  export BASHBOT_VAR "/var/spool/bashbot"

  /usr/local/telegram-bot-bash/bashbot.sh start
```

#### Unix like config for one bot. bashbot.sh is installed in '/usr/bin'
```bash
  # Note: all dirs and files must exist!
  export BASHBOT_ETC "/etc/bashbot"
  export BASHBOT_VAR "/var/spool/bashbot"
  export BASHBOT_JSONSH "/var/spool/bashbot"

  /usr/local/bin/bashbot.sh start
```

#### simple multibot config, everything is keept inside 'telegram-bot-bash' dir
```bash
  # config for running Bot 1
  # Note: all dirs and files must exist!
  export BASHBOT_ETC "./mybot1"
  export BASHBOT_VAR "./mybot1"

  /usr/local/telegram-bot-bash/bashbot.sh start
```

```bash
  # config for running Bot 2
  # Note: all dirs and files must exist!
  export BASHBOT_ETC "./mybot2"
  export BASHBOT_VAR "./mybot2"

  /usr/local/telegram-bot-bash/bashbot.sh start
```
