 """Hook the current excepthook to the backtrace. If `align` is True, all parts (line numbers, file names, etc..) will be aligned to the left according to the longest entry. If `strip_path` is True, only the file name will be shown, not its full path. If `enable_on_envvar_only` is True, only if the environment variable `ENABLE_BACKTRACE` is set, backtrace will be activated. If `on_tty` is True, backtrace will be activated only if you're running in a readl terminal (i.e. not piped, redirected, etc..). If `convervative` is True, the traceback will have more seemingly original style (There will be no alignment by default, 'File', 'line' and 'in' prefixes and will ignore any styling provided by the user.) See https://github.com/nir0s/backtrace/blob/master/README.md for information on `styles`. """
