|Nc@sEdZddlZddlZddlmZdddYZdS(sk HyperParser =========== This module defines the HyperParser class, which provides advanced parsing abilities for the ParenMatch and other extensions. The HyperParser uses PyParser. PyParser is intended mostly to give information on the proper indentation of code. HyperParser gives some information on the structure of code, used by extensions to help the user. iN(tPyParset HyperParsercBsteZdZdZdZdZdedZdZe j e j dZ e j dZ dZd ZRS( cCs||_|j|_}tj|j|j}d}||j|}|jsx|jD]}t ||d}t |d} d|} |j |j | | d|j |j| } | d k s|dkrbPqbqbW|j| pdn_|jd|} | r%| d} nd} d|} |j |j | | d|jd|jd |_| |_|j|_gtt|jD]8} | dko|j| d|j| ddk^q|_|j|d S( s[Initialize the HyperParser to analyze the surroundings of the given index. cSstt|S(N(tinttfloat(tindex((s(C:\RCS\Python\lib\idlelib\HyperParser.pyt index2linesis.0s%d.ends itconsoles1.0iN(teditwinttextRtParsert indentwidthttabwidthRtcontext_use_ps1tnum_context_linestmaxtreprtset_strtgettfind_good_parse_startt_build_char_in_string_functNonetset_lot tag_prevrangetstrtrawtextt stopatindextget_last_stmt_bracketingt bracketingtrangetlentisopenert set_index(tselfRRRtparserRtlnotcontexttstartatt startatindexRtbodtrti((s(C:\RCS\Python\lib\idlelib\HyperParser.pyt__init__s:        TcCst|jt|jj||j}|dkrFtdn||_d|_xP|jt|jdkr|j|jdd|jkr|jd7_q[W|jt|jdkr|j|jdd|jkr|j |jd r|jd7_ndS(siSet the index to which the functions relate.
