Description

This article describes a new pasting behavior which is smarter than the regular paste-as-it-is behavior in terms of indentation. However the implementation will remain simple without using heavy Eiffel parser to reformat the text being pasted.

Behaviors

Note:

• Number of tabulations before the cursor (NC)
• Number of leading tabulations of the text being pasted (NP)

Behavior 1: Multiple lines with leading tabs in pasting text

Copied text:

Behavior 1.1

Pasted at:

Result:

Summury:

• Remove tabs before the cursor.
• The text pasted is indented by one tabulation (NC - NP)

Behavior 1.2

Pasted at:

Result:

Summury:

• Remove tabs before the cursor.
• The text pasted is not modified when (NC - NP) = 0

Behavior 1.3

Pasted at:

Result:

Summury:

• Nothing has been done to the pasted text when NC = 0

Behavior 2: Multiple lines with no tab in pasting text

Copied text:

Behavior 2.1

Pasted at:

Result:

Summury:

• Nothing has been done to the pasted text when NP = 0

Behavior 2.2

Pasted at:

Result:

Summury:

• Nothing has been done to the pasted text when NP = 0

Behavior 3: Single line with leading tabs in pasting text

Copied text:

Behavior 3.1

Pasted at:

Result:

Summury:

• Remove tabs before the cursor.
• The text pasted is indented by one tabulation (NC - NP)

Behavior 3.2

Pasted at:

Result:

Summury:

• Remove tabs before the cursor.
• The text pasted is not modified when (NC - NP) = 0

Behavior 3.3

Pasted at:

Result:

Summury:

• Nothing is done to the text pasted when NC = 0

Behavior 4

Copied text:

Behavior 4.1

Pasted at:

Result:

Summury:

• Remove tabs before the cursor.
• The text pasted is indented by one tabulation (NC - NP)
• This is a good example to show this pasting behavior's advantage. Paste-as-it-is requires 4 steps to get this result.
