The format config page is missing documentation for the following options:

• align_chain_expr
• align_continuous_inline_comment
• align_continuous_line_space
• align_continuous_similar_call_args
• break_before_braces
• keep_indents_on_empty_lines
• line_space_around_block
• table_separator_style

maintaining up-to-date documentation is a challenging task, especially when I have multiple projects to maintain. However, the meaning of most of the options I provide can be understood from their names. In fact, you can refer to the tests, as they cover almost every option. I also have plans to spend time writing documentation, but when I see that my repository has less than 100 stars, it demotivates me. So, I can only wait for a boring period of time to work on it again.
