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

In general: Adjust the number of leading tabs for each line in the pasting text by the result of the number of existing tabs before the editor cursor subtracting the number of leading tabs in the pasting text.

Except:

  • There is a non-tabulation character before the editor cursor
  • NC = 0
  • NP = 0

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 copied text.PNG

Behavior 1.1

Pasted at:

Behavior 1 1 pasted at.PNG

Result:

Behavior 1 1 result.PNG

Summury:

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

Behavior 1.2

Pasted at:

Behavior 1 2 pasted at.PNG

Result:

Behavior 1 2 result.PNG

Summury:

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

Behavior 1.3

Pasted at:

Behavior 1 3 pasted at.PNG

Result:

Behavior 1 3 result.PNG

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 copied text.PNG

Behavior 2.1

Pasted at:

Behavior 2 1 pasted at.PNG

Result:

Behavior 2 1 result.PNG

Summury:

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

Behavior 2.2

Pasted at:

Behavior 2 2 pasted at.PNG

Result:

Behavior 2 2 result.PNG

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 copied text.PNG

Behavior 3.1

Pasted at:

Behavior 3 1 pasted at.PNG

Result:

Behavior 3 1 result.PNG

Summury:

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

Behavior 3.2

Pasted at:

Behavior 3 2 pasted at.PNG

Result:

Behavior 3 2 result.PNG

Summury:

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

Behavior 4.1

Pasted at:

Behavior 4 1 pasted at.PNG

Result:

Behavior 4 1 result.PNG

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.

Behavior 5: Multiple lines with improperly formatted pasting text

Copied text:

Behavior 5 copied text.PNG

Behavior 5.1

Pasted at:

Behavior 5 1 pasted at.PNG

Result:

Behavior 5 1 result.PNG

Summury:

  • Remove tabs before the cursor.
  • The text pasted is indented by one tabulation (NC - NP)
  • The result is not perfect before the copied text is improperly formatted. One has to adjust it manually after pasting.

Behavior 6: Paste immediately after copy

Copied text:

Behavior 6.1

Pasted at:

Behavior 5 copied text.PNG

Result:

Behavior 6 1 result.PNG

Summury:

  • Paste as it is if the selection is the same as the text being pasted.
