File Merge
The defFileMerge
function allows you to register a custom callback to override the default file merge behavior.
This can be useful for merging files in a different way than the default, for example, to merge files in a different format.
The function is called for all files; return the merged content or undefined
to skip.
You can define multiple file merge callbacks, they will be executed in order of registration.
Example: content appender
The callback below appends the content in generated .txt
files.
