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 cCsm||_||_|j\|_|_|jd|_|jd|_d|_d|_|jddS(Ni( R t insert_modetgetmaxyxtmaxytmaxxt stripspacestNonetlastcmdtkeypad(tselfR R((s&/usr/lib64/python2.7/curses/textpad.pyt__init__+s    cCs{|j}xktrvtjj|jj||tjjkrYt|j|d}Pn|dkriPn|d}q W|S(suGo to the location of the first blank on the given line, returning the index of the last non-blank character.ii(RtTrueRtasciiR tinchtSPtmin(Rtytlast((s&/usr/lib64/python2.7/curses/textpad.pyt _end_of_line5s  - cCs|jj\}}||jks3||jkr|jrN|jj}ny|jj|Wntjk rxnX|jr|jj\}}tj j |r|j ||jj ||qqndS(N( R tgetyxRRRRRRterrorRtisprintt_insert_printable_chartmove(RtchR txtoldchtbackytbackx((s&/usr/lib64/python2.7/curses/textpad.pyR&Bs   cCse|jj\}}||_tjj|ra||jksN||jkra|j|qan|tjj kr|jj |dn|tjj tj tjj tjfkr`|dkr|jj ||dnY|dkrnJ|jr|jj |d|j|dn|jj |d|j|tjj tjfkra|jjqan|tjjkr|jjn|tjjkr|jr|jj ||j|qa|jj ||jn|tjjtjfkrE||jkr|jj ||dqa||jkr+qa|jj |ddn|tjjkr[dS|tjjkr|jdkrdS||jkra|jj |ddqan|tjjkr|dkr|j|dkr|jjqa|jj |||jjnO|tjjkr4|jjn-|tjjtjfkr||jkra|jj |d|||j|dkr|jj |d|j|dqqan|tjjkr|jj n|tjj!tj"fkra|dkra|jj |d|||j|dkr^|jj |d|j|dq^qandS(s!Process a single editing command.ii(#R R#RRRR%RRR&tSOHR'tSTXtKEY_LEFTtBSt KEY_BACKSPACERR"tdelchtEOTtENQtACKt KEY_RIGHTtBELtNLtVTtdeletelntclrtoeoltFFtrefreshtSOtKEY_DOWNtSItinsertlntDLEtKEY_UP(RR(R R)((s&/usr/lib64/python2.7/curses/textpad.pyt do_commandTsp *   ' !- -c Csd}xt|jdD]}|jj|d|j|}|dkr]|jr]qnx_t|jdD]J}|jr||krPn|ttj j |jj ||}qqW|jdkr|d}qqW|S(s.Collect and return the contents of the window.tiis ( trangeRR R'R"RRtchrRRR(RtresultR tstopR)((s&/usr/lib64/python2.7/curses/textpad.pytgathers/cCs`xS|jj}|r'||}n|s3qn|j|sFPn|jjq|jS(s2Edit in the widget window and collect the results.(R tgetchRDR=RJ(RtvalidateR(((s&/usr/lib64/python2.7/curses/textpad.pyteditsN( t__name__t __module__t__doc__tFalseRR"R&RDRJRRM(((s&/usr/lib64/python2.7/curses/textpad.pyRs  @ t__main__cCsd\}}d \}}|j|d|dtj||||}t||d|d|||||jt|jS( Ni iiiisUse Ctrl-G to end editing.i(i i(ii(taddstrRtnewwinRR=RRM(tstdscrtncolstnlinesR R R ((s&/usr/lib64/python2.7/curses/textpad.pyt test_editboxs  & sContents of text box:(( RPRt curses.asciiRRRNRXtwrappertstrtrepr(((s&/usr/lib64/python2.7/curses/textpad.pyts
