The kitty text sizing protocol allows terminal apps to explicitly tell terminals how many cells text occupies, using the escape sequence:: ESC ] 66 ; metadata ; text BEL/ST Metadata is colon-separated ``key=value`` pairs: - ``s``: scale - ``w``: width in cells - ``n``: fractional numerator - ``d``: fractional denominator - ``v``: vertical alignment - ``h``: horizontal alignment Parsing is pretty straight-forward: - When ``w > 0``, return ``s * w``. - Otherwise ``w == 0``, ``s * wcswidth(inner_text_width)`` cells. Numerator, denominator, and alignment codes and values are parsed but otherwise ignored and have no effect on measurements made in this library. .. _`kitty text sizing protocol`: https://sw.kovidgoyal.net/kitty/text-sizing-protocol/ .. versionadded:: 0.7.0 ) annotationsN)wcswidthc8eZdZUded<ded<ded<ded<dS) _FieldMetastrnameintlowhighdefaultN)__name__ __module__ __qualname____annotations__`/var/www/finuniver-perm.ru/html/student/venv/lib/python3.11/site-packages/wcwidth/text_sizing.pyrr*s4 III HHH IIILLLLLrrscale)r r r r width numerator denominatorvertical_alignhorizontal_align)swndvhzdict[str, _FieldMeta]TEXT_FIELD_MAPPINGceZdZUdZdZded<dZded<dZded<dZded<dZ ded <dZ ded <dd Z ddZ e dddZdS)TextSizingParamsa/ Parsed parameters from a text sizing escape sequence (OSC 66). :param scale: Scale factor (1-7).
