Supports the following Emacs-like key bindings: Ctrl-A Go to left edge of window. Ctrl-B Cursor left, wrapping to previous line if appropriate. Ctrl-D Delete character under cursor. Ctrl-E Go to right edge (stripspaces off) or end of line (stripspaces on). Ctrl-F Cursor right, wrapping to next line when appropriate. Ctrl-G Terminate, returning the window contents. Ctrl-H Delete character backward. Ctrl-J Terminate if the window is 1 line, otherwise insert newline. Ctrl-K If line is blank, delete it, otherwise clear to end of line. Ctrl-L Refresh screen. Ctrl-N Cursor down; move down one line. Ctrl-O Insert a blank line at cursor location. Ctrl-P Cursor up; move up one line. Move operations do nothing if the cursor is at an edge where the movement is not possible. The following synonyms are supported where possible: KEY_LEFT = Ctrl-B, KEY_RIGHT = Ctrl-F, KEY_UP = Ctrl-P, KEY_DOWN = Ctrl-N KEY_BACKSPACE = Ctrl-h Fc C s? | | _ | | _ | j � d | _ d | _ | j d � d S)Nr )r � insert_mode�_update_max_yx� stripspaces�lastcmdZkeypad)�selfr r r r r �__init__+ s zTextbox.__init__c C s3 | j j � \ } } | d | _ | d | _ d S)Nr )r Zgetmaxyx�maxy�maxx)r r r r r r r 3 s zTextbox._update_max_yxc C s| | j � | j } xb t j j | j j | | � � t j j k r] t | j | d � } Pn | d k rj P| d } q W| S)zuGo to the location of the first blank on the given line, returning the index of the last non-blank character.r r )r r r �asciir �inchZSP�min)r �yZlastr r r � _end_of_line8 s - zTextbox._end_of_linec C s� | j � | j j � \ } } d } x� | | j k sF | | j k r� | j r^ | j j � } y | j j | � Wn t j k r� Yn X| j s� t j j | � r� P| } | j j � \ } } | d k r( | | f } q( W| d k r� | j j | � d S)N) r r �getyxr r r r r r �errorr �isprint�move)r �chr �xZbackyxZoldchr r r �_insert_printable_charF s$ ! z Textbox._insert_printable_charc C sW | j � | j j � \ } } | | _ t j j | � rh | | j k sX | | j k rS| j | � n�| t j j k r� | j j | d � n�| t j j t j t j j t j f k rd| d k r� | j j | | d � nY | d k r� nJ | j r | j j | d | j | d � � n | j j | d | j � | t j j t j f k rS| j j � n�| t j j k r�| j j � n�| t j j k r�| j r�| j j | | j | � � qS| j j | | j � nz| t j j t j f k rI| | j k r | j j | | d � qS| | j k r/qS| j j | d d � n | t j j k r_d S| t j j k r�| j d k r�d S| | j k rS| j j | d d � n�| t j j k r| d k r�| j | � d k r�| j j � qS| j j | | � | j j � n@| t j j k r5| j j � n | t j j t j f k r�| | j k rS| j j | d | � | | j | d � k rS| j j | d | j | d � � n� | t j j k r�| j j! � n{ | t j j" t j# f k rS| d k rS| j j | d | � | | j | d � k rS| j j | d | j | d � � d S)z!Process a single editing command.r r )$r r r r r r r r r r ZSOHr ZSTXZKEY_LEFTZBSZ KEY_BACKSPACEr r ZdelchZEOTZENQZACKZ KEY_RIGHTZBEL�NLZVTZdeletelnZclrtoeolZFF�refresh�SOZKEY_DOWNZSIZinsertlnZDLEZKEY_UP)r r r r r r r � do_command_ sr * ' !' $zTextbox.do_commandc C s� d } | j � x� t | j d � D]� } | j j | d � | j | � } | d k rd | j rd q$ x\ t | j d � D]G } | j r� | | k r� P| t t j j | j j | | � � � } qx W| j d k r$ | d } q$ W| S)z.Collect and return the contents of the window.� r r � ) r �ranger r r r r r �chrr r r )r �resultr �stopr r r r �gather� s /zTextbox.gatherNc C sX xK | j j � } | r$ | | � } | s- q | j | � s= P| j j � q W| j � S)z2Edit in the widget window and collect the results.)r Zgetchr# r! r* )r Zvalidater r r r �edit� s z Textbox.edit) �__name__� __module__� __qualname__�__doc__r r r r r# r* r+ r r r r r s A r �__main__c C s� d \ } } d \ } } | j | d | d � t j | | | | � } t | | d | d | | | | � | j � t | � j � S) N� � � � � zUse Ctrl-G to end editing.r )r1 r2 )r3 r4 )Zaddstrr Znewwinr r! r r+ )ZstdscrZncolsZnlinesr r r r r r � test_editbox� s & r6 zContents of text box:) r/ r Z curses.asciir r r, r6 �wrapper�str�print�reprr r r r �<module> s �
