What are Code Templates?

Code Templates are texts with an abbreviation. For example: You can type 'cl' in the source editor and then type Ctrl+J to invoke the code templates starting with 'cf'. This feature is a great time saver.

This dialog allows you to edit the existing or add your own templates.

The texts can contain macros. And you can add your own macros by creating a design time package and using the macrointf.pas of the IDEIntf package.

Example 1 - ifb



The pipe should represent the cursor. Press Ctrl+j. It will be expanded to

  if | then begin


Again the pipe represents the cursor. You can see the cursor has moved as well.

This template is called 'ifb' and is defined as follows:

if | then begin


This time the pipe '|' is a real character. It defines the cursor position after inserting the template.

Example 2 - Using macros

This example shows how to create a code template 'w' which inserts a line with the current procedure name.

  • Click on the 'Add' button. A dialog pops up. Set Token to 'w' and Comment to 'writeln(ProcName)', then click Ok.
  • Your new item has been added to the list box.
  • In the source below fill in
 writeln(' ',|);
  • The pipe is really a pipe and defines the new cursor position. Now place the cursor after the first ' and click on the 'Insert macro' button. A dialog pops up showing all available code macros. Choose 'ProcedureName' nd click 'Insert Macro'. You should now have:
 writeln('$ProcedureName() ',|);
  • Click 'Ok' to save and close the code template dialog.
  • Move the cursor into a method body, type 'w':

For instance:

 procedure TForm1.FormDestroy(Sender: TObject);

The pipe should represent here the blinking cursor, not a character.

  • Press Ctrl+j. You will get:
 procedure TForm1.FormDestroy(Sender: TObject);
   writeln('TForm1.FormDestroy ',|);
