Sometimes you need to fully LaTeX-encode a string that already has some LaTeX constructs. For instance, titles of bibliographic entries might include some inline math or accents, but they might also include unicode characters that need to be encoded. Using a :py:class:`UnicodeToLatexEncoder` on such strings would result in ugly doubly-escaped strings such as ``\textbackslash{}'\{e\}``. Instead, constructs such as ``\'{e}`` should be preserved while other characters and/or constructs (say '&' or '%') as well as unicode characters should be encoded. This class offers a simple partial solution: Characters are encoded as per the given `conversion_rules` (or the default conversion rules of :py:class:`UnicodeToLatexEncoder` objects), except that the characters in `keep_latex_chars` are to be interpreted as LaTeX and are not to be further encoded. .. versionadded: 2.10 \${}^_Nc |}|dg}tt|jddtt|jdg|zi|||_dS)Ndefaultsconversion_rulesnone) rule_typerulereplacement_latex_protection)superr __init__rr_do_partial_latex_encode_stepkeep_latex_chars)selfrrkwargsbase_conversion_rules __class__s /var/www/development/aibuddy-work/election-extract/venv/lib/python3.11/site-packages/pylatexenc/latexencode/_partial_latex_encoder.pyrz#PartialLatexToLatexEncoder.__init__Es !1 (%/L !8($//8 ;'7-3' '  !1cddlm}|||jvr\||d}||d}|j||j|j|jzz}|j|jz|z |fSdS)aY This method is used as a "callable rule" for the :py:class:`UnicodeToLatexEncoder` object. The strategy is to see if we have something that looks like a LaTeX char we want to keep. If so, keep it as is; if not, return `None` so that further rules can be considered by the base unicode encoder. ) LatexWalkerF)tolerant_parsing) environmentsN) latexwalkerr!r get_token pre_spaceposlen)rsr'r!lwtok tok_as_latexs rrz8PartialLatexToLatexEncoder._do_partial_latex_encode_step\s .----- S6T* * *Q777B,,s,77C=1SWswsw-F+GGLGCGOc)<8 8tr)r N)__name__ __module__ __qualname____doc__rr __classcell__)rs@rr r .s\0?C111111.rr ) __future__rrrlogging getLoggerr-logger_unicode_to_latex_encoderrrr r rrrr7s4IHHHHHHHHH  8 $ $EEEEE!6EEEEEr
