A common problem in IDLE's interactive shell is printing of large amounts of text into the shell. This makes looking at the previous history difficult. Worse, this can cause IDLE to become very slow, even to the point of being completely unusable. This extension will automatically replace long texts with a small button. Double-cliking this button will remove it and insert the original text instead. Middle-clicking will copy the text to the clipboard. Right-clicking will open the text in a separate viewing window. Additionally, any output can be manually "squeezed" by the user. This includes output written to the standard error stream ("stderr"), such as exception messages and their tracebacks. � N)�Font)�idleConf)� view_text)�Hovertip)�macosx�P � c C s� d}d}d}x�t jd| �D ]�}|j� | }||7 }||7 }| | dkrT|d7 }d}n4| | dksdt�|||| 7 }||kr�|d7 }|}|d7 }|dkrt|d |�\}} ||7 }| d }qW |t| �| 7 }|dkr�||d | 7 }n|d8 }|S )z�Count the number of lines in a given string.

A user can then use the button to replace it with the original text, copy the original text to the clipboard or view the original text in a separate window. Each button is tied to a Squeezer instance, and it knows to update the Squeezer instance when it is expanded (and therefore removed). c s� � | _ || _|| _|| _|j | _}|j | _}|jj| _d| j }t j j | ||ddd� d}t | |dd� | j d| j� tj� r�| j d | j� n| j d | j� | j� fd d �� d | _| j| j� d S ) NzSqueezed text (%d lines).z#FFFFC0z#FFFFE0)�textZ backgroundZactivebackgroundz5Double-click to expand, right-click for more options.r )Z hover_delayz<Double-Button-1>z <Button-2>z <Button-3>c s � t | �t | �t |� � S )N)�int)�offsetZlength)r r r �<lambda>} s z*ExpandingButton.__init__.<locals>.<lambda>)r �tags� numoflines�squeezer�editwinr �per�bottom� base_text�tk�Button�__init__r Zbind�expandr ZisAquaTk�context_menu_eventZselection_handle� is_dangerousZ after_idle�set_is_dangerous) �selfr r" r# r$ r% r Z button_textZbutton_tooltip_textr )r r r+ a s( zExpandingButton.__init__c sL d| j j� � | jdkpDt| j�dkpDt� fdd�tjd| j�D ��| _d S )N�2 i� iP� c 3 s | ]}t |jd ��� kV qdS )r N)r �group)�.0Z line_match)�dangerous_line_lenr r � <genexpr>� s z3ExpandingButton.set_is_dangerous.<locals>.<genexpr>z[^\n]+) r � winfo_widthr# r r �anyr r r. )r0 r )r4 r r/ � s z ExpandingButton.set_is_dangerousNc C s� | j dkr| j� | j rTtjddjddddg�| jt| j�f tj| j d�}|sTd S | j j | j j | �| j| j � | j j| � | jjj| � dS ) aA expand event handler This inserts the original text in place of the button in the Text widget, removes the button and updates the Squeezer instance.
