Creating a LiveCode Builder Library
Start by creating a new directory to develop your extension in.
When you package an extension a number of files are created. The Extension Builder currently relies on there being only one .lcb file in a given directory. Because of this it is simplest to create a new directory for each extension you create.
The extension files that are created include an API file, manifest and compiled module file.
Create a new plain text file in the directory and save it to disk with the extension “.lcb”.
It’s important to use the “.lcb” extension so your chosen text editor applies LiveCode Builder formatting to your code, if available.
I am naming my file “helloWorldLibrary.lcb” but you can name your file anything suitable.
