]c@ssdZddlZddlZddlmZdd dYZedkroddlZejddd ndS( sProvide advanced parsing abilities for ParenMatch and other extensions. HyperParser uses PyParser. PyParser mostly gives information on the proper indentation of code. HyperParser gives additional information on the structure of code. 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;To initialize, analyze the surroundings of the given index.cSstt|S(N(tinttfloat(tindex((s$lib/python2.7/idlelib/HyperParser.pyt index2linesis.0s%d.ends itconsoles1.0iN(teditwinttextRtParsert indentwidthttabwidthRtcontext_use_ps1tnum_context_linestmaxtreprtset_strtgettfind_good_parse_startt_build_char_in_string_functNonetset_lot tag_prevrangetstrtrawtextt stopatindextget_last_stmt_bracketingt bracketingtrangetlentisopenert set_index(tselfRRRtparserRtlnotcontexttstartatt startatindexRtbodtrti((s$lib/python2.7/idlelib/HyperParser.pyt__init__s:        TcCst|jt|jj||j}|dkrJtd|n||_d|_xP|jt|jdkr|j|jdd|jkr|jd7_q_W|jt|jdkr|j|jdd|jkr|j |jd r|jd7_ndS(sgSet the index to which the functions relate.
