## Install bashbot

1. Go to the directory you want to install bashbot, e.g.
    * your $HOME directory (install and run with your user-ID)
    * /usr/local if you want to run as service
2. [Download latest release zip from github](https://github.com/topkecleon/telegram-bot-bash/releases) and extract all files. 
3. Change into the directory ```telegram-bot-bash```
4. Acticate the bot example commands  ``cp mycommands.sh.dist mycommands.sh```
5. Run ```./bashbot.sh init``` to setup the environment and enter your Bots token given by botfather.

Edit 'mycommands.sh to your needs.
Now your Bot is ready to start ...

**If you are new to Bot development read [Bots: An introduction for developers](https://core.telegram.org/bots)**

### Install from Github

As an alternative to download the zip files, you can clone the github repository to get the latest improvements/fixes.

1. Go to the directory you want to install bashbot, e.g.
    * your $HOME directory (install and run with your user-ID)
    * /usr/local if you want to run as service
2. Run ```git clone https://github.com/topkecleon/telegram-bot-bash.git```
3. Change into the directory ```telegram-bot-bash```
4. Run ``` test/ALL-tests.sh``` and if everything finish OK ...
5. Run ```sudo ./bashbot.sh init``` to setup the environment and enter your Bots token given by botfather.

###  Update bashbot

**Note: all files including 'mycommands.sh' may overwritten, make a backup!**

1. Go to the directory where you had installed bashbot, e.g.
    * your $HOME directory
    * /usr/local
2. [Download latest release zip from github](https://github.com/topkecleon/telegram-bot-bash/releases)
3. Stop all running instances of bashbot
4. Extract all files to your existing bashbot dir 
5. Run ```sudo ./bashbot.sh init``` to setup your environment after the update

If you modified ```commands.sh``` move your changes to ```mycommands.sh```, this avoids overwrrite of you changes on updates.

Now you can restart your bashbot instances.

### Note for BSD and MacOS

**On MacOS** you must install a more recent version of bash, as the default bash is way to old,
see e.g. [Install Bash on Mac](http://macappstore.org/bash/)

**On BSD and MacOS** I recommend to install gnu coreutils and include them in front of your PATH
environment variable before running bashbot, e.g. the gnu versions of sed, grep, find ...

I considered to make bashbot BSD sed compatible, but much of the bashbot "magic" relies on
(gnu) sed features, e.g. alternation ```|```, non printables ```\n\t\<``` or repeat ```?+``` pattern, not supported by BSD sed.
BSD/MacOS sed compatibility will result in a rewrite of all grep/sed commands with an uncertain outcome,
see [BSD/MacOS vs. GNU sed](https://riptutorial.com/sed/topic/9436/bsd-macos-sed-vs--gnu-sed-vs--the-posix-sed-specification)
to get an impression how different they are.

In adition you must adjust the shebang line of the scripts ```bashbot.sh``` and ```json.sh``` to point to to the correct bash
or use the example script: ```examples/bash2env *.sh */*.sh```

Bashbot will stay with /bin/bash shebang, as using a fixed path is more secure than the portable /usr/bin/env variant, see
[Security Considerations](../README.md#Security-Considerations)

### Notes on Updates

#### removal of TMUX
From version 0.80 on TMUX is no longer needed and the bachsbot command 'attach' is deleted. Old function 'inproc'
is replaced by 'send_interactive'. send_interactive does checks if an interactive job is running internally.
Pls check if you make use of inproc and remove it including the old checks, e.g.
```bash
if tmux ls | grep -v send | grep -q "$copname"; then inproc; fi
# or
[ checkprog ] && inproc
```
must be replaced by ```send_interactive "${CHATD[ID]}" "${MESSAGE}"```

### Do not edit commands.sh
From version 0.60 on your commands must be placed in 'mycommands.sh'. If you update from a version with your commands
in 'commands.sh' move all your commands and functions to 'mycommands.sh'.

From version 0.80 on 'commands.sh' will be overwritten on update!

#### Location of var / tmp / data dirs
From version 0.70 on the tmp dir is renamed to 'data-bot-bash' to reflect the fact that not only temporary files are stored. an existing 'tmp-bot-bash' will be automatically renamed after update.

From version 0.50 on the temporary files are no more placed in '/tmp'. instead a dedicated tmp dir is used.

#### Changes to send_keyboard in v0.6
From Version 0.60 on keyboard format for ```send_keyboard``` and ```send_message "mykeyboardstartshere ..."``` was changed.
Keyboards are now defined in JSON Array notation e.g. "[ \\"yes\\" , \\"no\\" ]".
This has the advantage that you can create any type of keyboard supported by Telegram.
The old format is supported for backward compatibility, but may fail for corner cases.

*Example Keyboards*:

- yes no in two rows:
    - OLD format: 'yes' 'no' *(two strings)*
    - NEW format: '[ "yes" ] , [ "no" ]' *(two arrays with a string)*
- new layouts made easy with NEW format:
    - Yes No in one row: '[ "yes" , "no" ]'
    - Yes No plus Maybe in 2.row: '[ "yes" , "no" ] , [ "maybe" ]' 
    - numpad style keyboard: '[ "1" , "2" , "3" ] , [ "4" , "5" , "6" ] , [ "7" , "8" , "9" ] , [ "0" ]'
