N)Path) Application)BaseIPythonApplication)BoolIntDict) ask_yes_nozTrim the IPython history database to the last 1000 entries. This actually copies the last 1000 entries to a new database, and then replaces the old file with the new. Use the `--keep=` argument to specify a number other than 1000. aClear the IPython history database, deleting all entries. Because this is a destructive operation, IPython will prompt the user if they really want to do this. Passing a `-f` flag will force clearing without a prompt. This is an handy alias to `ipython history trim --keep=0` c@sjeZdZeZedddjddZedddjddZ e e dddiiej fd Z e e d d Zd d ZdS) HistoryTrimFz/Keep the old history file as history.sqlite.helpTconfigi/Number of recent lines to keep in the database.backup)rzHistoryTrim.keep)keepc Cst|jj}|d}t|}t|d|jdf}t||jkr/t d|jt ddSt d|j| | |rX|dd}t|d|f}t|d |f}| |d }d} | rv| d7} |d t| }| sft|} | d | d | d | |r| | d|| d|| d|Wdn1swY| |jrd} |d| } | r| d7} |d| } | s|| t d| n|||dS)Nzhistory.sqlitez^SELECT session, line, source, source_raw FROM history ORDER BY session DESC, line DESC LIMIT ?rz=There are already at most %d entries in the history database.z>Not doing anything.
