I’ve written an indent_string/3 and am porting the Python test cases for textwrap.indent and textwrap.dedent.
In the process, I’ve discovered a few differences between Python’s textwrap.dedent and library(string)'s dedent_string/3, particularly with the handling of empty lines. I’ll start a new discussion on this once I’ve finished porting the test cases. I’ll also discuss split_lines, and why we might want something different from split_string(In, "\n", "", Lines).
