LCB Library Definition

The first thing we need to do is declare the type of extension we are writing.

We are writing a library and so we need to declare the extension as such.

The library declaration is followed by an identifier. An extension identifier should be in the form

community.livecode.<user name>.<library name>

In my case my username is “elanorb” and I have chosen to use “helloworld” as the name part of the identifier.

library community.livecode.elanorb.helloworld


end library

LCB module naming

The module name uses reverse DNS notation. For example, a module created by the Example Organisation would use module names beginning with org.example.

You must only use module names corresponding to domain names that you control or are allowed to use.

If you don’t have a domain name of your own, you may use module names beginning with community.livecode.. For example, if your username is “sophie”, then you can create a module named community.livecode.sophie.mymodule.

Always write module names in lower case.
