This function extracts a substring based on visible column positions rather than character indices. Terminal escape sequences are preserved in the output since they have zero display width. If a wide character (width 2) is split at either boundary, it is replaced with ``fillchar``. TAB characters (``\t``) are expanded to spaces up to the next tab stop, controlled by the ``tabsize`` parameter. When cursor movement is detected, a "painter's algorithm" is used, cursor movements actively change the write position, allowing cursor-left and carriage return to overwrite previously written cells. It is assumed that ``text`` begins at column 0. **OSC 8 hyperlinks** are handled specially: the visible text inside a hyperlink is clipped to the requested column range, and the hyperlink is rebuilt around the clipped text. Empty hyperlinks (those with no remaining visible text after clipping) are removed:: >>> clip('\x1b]8;;http://example.com\x07Click This link\x1b]8;;\x07', 6, 10) '\x1b]8;;http://example.com\x07This\x1b]8;;\x07' :param text: String to clip, may contain terminal escape sequences. :param start: Absolute starting column (inclusive, 0-indexed). :param end: Absolute ending column (exclusive). :param fillchar: Character to use when a wide character must be split at a boundary (default space). Must have display width of 1. :param tabsize: Tab stop width (default 8). Set to 0 to pass tabs through as zero-width (preserved in output but don't advance column position). :param ambiguous_width: Width to use for East Asian Ambiguous (A) characters. Default is ``1`` (narrow). Set to ``2`` for CJK contexts. :param propagate_sgr: If True (default), SGR (terminal styling) sequences are propagated. The result begins with any active style at the start position and ends with a reset sequence if styles are active. :param control_codes: How to handle control characters and sequences: - ``'parse'`` (default): Track horizontal cursor movement and clip hyperlink text. Cursor overwrite is always allowed, with best effort results; indeterminate sequences (home, clear, reset, etc.) are preserved as zero-width. - ``'strict'``: Like ``parse``, but raises :exc:`ValueError` on sequences with indeterminate effects (cursor home, clear screen, reset, vertical movement, etc.) matching :func:`width` behavior. Also raises on out-of-bounds horizontal cursor movement. - ``'ignore'``: All control characters are treated as zero-width. Cursor movement is not tracked (fastest path). :param overtyping: Whether to use the painter's algorithm for cursor movement (``\b`` backspace, ``\r`` carriage return, and CSI cursor left/right/position sequences). When ``None`` (default), auto-detects by scanning for these characters in *text*. Set to ``False`` for improved performance when the caller knows *text* contains no cursor movement characters. Set to ``True`` to force the painter's algorithm (useful for testing). Has no effect when ``control_codes='ignore'``. :returns: Substring of ``text`` spanning display columns (start, end), with all terminal sequences preserved and wide characters at boundaries replaced with ``fillchar``. :raises ValueError: If ``control_codes='strict'`` and an indeterminate-effect sequence or out-of-bounds cursor movement is encountered. SGR (terminal styling) sequences are propagated by default. The result begins with any active style and ends with a reset:: >>> clip('\x1b[1;34mHello world\x1b[0m', 6, 11) '\x1b[1;34mworld\x1b[0m' Set ``propagate_sgr=False`` to disable this behavior. .. versionadded:: 0.3.0 .. versionchanged:: 0.5.0 Added ``propagate_sgr`` parameter (default True). .. versionchanged:: 0.7.0 Added ``control_codes`` parameter (default 'parse'). OSC 8 hyperlink-aware clipping. OSC 66 text sizing protocol support. Added ``overtyping`` parameter (default None, auto-detect). Example:: >>> clip('hello world', 0, 5) 'hello' >>> clip('中文字', 0, 3) # Wide char split at column 3 '中 ' >>> clip('a\tb', 0, 10) # Tab expanded to spaces 'a b' rr-rvFNignorerrrs) r<r=r>rIrAr?r@rsrB) rKisascii isprintablerrrsearchrrr;) r<r=r>r?r@rArIrBrhas_escfn_clips r&rLrLs-J qMME e||r ||~~$**,,E#InGW  X % K t^Jtt|JH$:A$GGHH   11 );mm|G GG  #')#     r%)r5r.r6r7r8r.)r<r.r=r*r>r*r?r.r@r*rAr*rBrCrDr rEr*rFr*r8r() rTrUrVrWr=r*r>r*r?r.r8r.)r<r.r=r*r>r*rIrrrAr*r?r.r@r*rsrrrBrCr8rt)rrrFr*r=r*r>r*r?r.rAr*rrr8r*)r<r.r=r*r>r*r?r.r@r*rAr*rIrrrBrCrrr8r.))r __future__rr itertoolsrtypingrrrr_widthr rr hyperlinkr r sgr_staterrrrr text_sizingrrescape_sequencesrrrEnumrr(r;rSrqrrrrLr$r%r&rsU00"""""" ::::::::::::$$$$$$1111111100000000000000 65555555>>>>>>>>>> tyz"    ????D4444nh+h+h+h+VRRRRjcXcXcXcXV:A!%HHHHHHHHr%
