@ -4,6 +4,22 @@ This section is about help and best practices for new bashbot developers. The ma
bashbot development is done on github. If you want to provide fixes or new features [fork bashbot on githup](https://help.github.com/en/articles/fork-a-repo) and provide changes as [pull request on github](https://help.github.com/en/articles/creating-a-pull-request).
### Modules and Addons
Modules live in ```modules/*.sh``` are bashbot functions factored out in seperate files, gouped by functionality. Main reason for creating modules was
to make bashbot.sh smaller and contain only initalisation and a basic set of functions. In addition not every functionality is needed ba every bot, so you can
e.g. disable inline or background processing by renaming the respective module files to 'module.sh.off'.
Modules must onyl use functions provieded by 'bahsbot.sh' or the module itself, no depedencies to other modules or addons must exist.
If a module function is called from 'bashbot.sh' for whatever reason, you must test with '_is_function' or '_execute_if_function' if the
module is availible.
Addons live in ```addons/*.sh.dist``` and are disabled by default. To activate an addon remove the dist from filename, e.g. ```cp addons/example.sh.dist addons/example.sh```. Addons have to register themself to BASHBOT_EVENTS at startup, e.g. to call a function everytime a message is recieved.
This is similar on how 'commands.sh' works, but imore flexible and a major difference: Addons are executed in the context of the main script,
while 'commands.sh' is executed as a seperate process.
This is why addons are time critical and must return as fast as possible and spawn every action as a seperate process or function with '&'!
If you want to send out a message from aa addon use ```send_message "${CHAT[ID]} "Message to send ..." &``` to not wait for completion, witch may take several seconds.
### Debugging Bashbot
In normal mode of operation all bashbot output is discarded.
To get these messages (and more) you can start bashbot in the current shell ```./bashbot.sh startbot```. Now you can see all output or erros from bashbot.
