This extension implements a pane at the top of each IDLE edit window which provides block structure hints. These hints are the lines which contain the block opening keywords, e.g. 'if', for the enclosing block. The number of hint lines is determined by the numlines variable in the CodeContext section of config-extensions.def. Lines which do not open blocks are not shown in the context hints pane. � N)�TOP�LEFT�X�W�SUNKEN)�maxsize)�idleConf�class�def�elif�else�except�finally�for�if�try�while�with�d i� z ^(\s*)(\w*)c C s | j | � j � S)N)�match�groups)�s�c� r �8/opt/alt/python34/lib64/python3.4/idlelib/CodeContext.py�<lambda> s r c @ s� e Z d Z d d g f g Z e j d d d d d d d �Z e j d d d d d d d �Z e j d d d d d d d �Z d d � Z d d d � Z d d � Z d d d d � Z d d � Z d d � Z d d � Z d S)!� CodeContextZoptions�!Code Conte_xt�<<toggle-code-context>>� extensionsZnumlines�type�int�default� �bgcolor�strZ LightGray�fgcolorZBlackc C s� | | _ | j | _ | j d | _ d | _ d g | _ d | _ t j d d d d d d d �} | r� | j � | j j d d � n | j j t | j � | j j t | j � d S)N�fontr � � Fr r �visibler �boolr" z<<toggle-code-context>>T���)r r, r) F)�editwin�text�textfont�label�info� topvisibler � GetOption�toggle_code_context_eventZsetvar�after�UPDATEINTERVAL� timer_event�FONTUPDATEINTERVAL�font_timer_event)�selfr- r* r r r �__init__" s zCodeContext.__init__Nc C s� | j sC| j j | j j f } d } xM | D]E } | t t | j � d � � 7} | t t | j d � � � 7} q.
