Each menu selection or shortcut key selection replaces the word with a different word with the same prefix. The search for matches begins before the target and moves toward the top of the editor. It then starts after the cursor and moves down. It then returns to the original word and the cycle starts again. Changing the current text line or leaving the cursor in a different place before requesting the next selection causes AutoExpand to reset its state. There is only one instance of Autoexpand. éNc@s<eZdZejejdZdd„Zdd„Zdd„Z dd „Z d S) Ú AutoExpandÚ_cCs|j|_|jj|_d|_dS)N)ÚtextÚbellÚstate)ÚselfZeditwin©rú#lib/python3.9/idlelib/autoexpand.pyÚ__init__s zAutoExpand.__init__c Csè|j d¡}|j dd¡}|js.| ¡}d}n*|j\}}}}||ksL||krX| ¡}d}|sh| ¡dS| ¡}|j dt|ƒd¡||} |dt|ƒ}|dkr®| ¡|j  d| ¡|j d¡}|j dd¡}||||f|_dS)z1Replace the current word with the next expansion.Úinsertúinsert linestartzinsert lineendrÚbreakzinsert - %d charsé) rÚindexÚgetrÚgetwordsrÚ getprevwordÚdeleteÚlenr ) rZeventZ curinsertZcurlineÚwordsrr ÚlineÚwordZnewwordrrr Úexpand_word_events.  zAutoExpand.expand_word_eventc CsÒ| ¡}|sgS|j dd¡}t d|d|¡}~|j dd¡}t d|d|¡}~|sd|sdgSg}i}| ¡|D]"}| |¡rˆqx| |¡|||<qx|D]"}| |¡r°q | |¡|||<q | |¡|S)z?Return a list of words that match the prefix before the cursor.z1.0zinsert wordstartz\bz\w+\bzinsert wordendÚend)rrrÚreÚfindallÚreverseÚappend) rrZbeforeZwbeforeZafterZwafterrÚdictÚwrrr r6s4       zAutoExpand.getwordscCsF|j dd¡}t|ƒ}|dkr:||d|jvr:|d}q||d…S)z)Return the word prefix before the cursor.r r rrN)rrrÚ wordchars)rrÚirrr rUs  zAutoExpand.getprevwordN) Ú__name__Ú __module__Ú __qualname__ÚstringZ ascii_lettersZdigitsr r rrrrrrr rs rÚ__main__)Úmainz!idlelib.idle_test.test_autoexpandé)Ú verbosity)Ú__doc__rr%rr"Zunittestr'rrrr Ús K
