Public Instance Methods

cached_file_data(path) { |content| ... } click to toggle source

Loads the contents of the file given by path. The content is then yielded to the provided block in case a block is given, and the returned value from that block is cached and returned by this method. If no block is given, the content is stored instead.

The cache is retained as long as the inode, mtime, and size of the file remains unchanged.

@param path [String] path to the file to be read @yieldparam content [String] the content that was read from the file @yieldreturn [Object] some result based on the content @return [Object] the content, or if a block was given, the return value of the block
