#content(options = {}, &block) ⇒ Object

The Log’s content. The content that is passed to the block can be controlled using options.

Recognized options are:

start_line

The start point, in lines, of the content to pass to the block. Omitting the parameter will result in content from the start of the file being passed. If the provided value is greater than the number of lines in the file, no content will be passed.

end_line

The end point, in lines, of the content to pass to the block. Omitting the parameter will result in content up to the end of the file being passed. If the provided value is greater than the number of lines in the file, content up to and including the last line in the file will be passed.
