anstrip is a minimal library to strip ANSI sequences from strings. | ||
It provides: | ||
- the regex pattern used by the functions of anstrip | ||
- `strip`, a function to remove all the escape sequences from a string | ||
- `auto_strip`, a function that is similar to `strip`, except that it only removes if the output is a TTY | ||
- `printed_length`, a function that returns the length of the string as seen on the screen | ||
