(* Utility to assist in inserting conditional defines. For example, to convert
|
|
OnCreate := @CreateHandler
|
|
to:
|
|
OnCreate := {$IFDEF FPC} @ {$ENDIF} CreateHandler
|
|
select @ and then use Edit, Insert $IFDEF (default shortcut Ctrl+Shift+D),
|
|
select "FPC,NONE" and hit rerurn. If you select one or more complete lines then the
|
|
conditional defines are put on sepearate lines as in:
|
|
{$IFDEF DEBUG}
|
|
Writeln('State= ', State)
|
|
{$ENDIF}
|
|
The choices are listed in abbreviated form so:
|
|
MSWINDOWS,UNIX => {$IFDEF MSWINDOWS} ... {$ENDIF} {$IFDEF UNIX} ... {$ENDIF}
|
|
FPC,ELSE => {$IFDEF FPC} ... {$ELSE} ... {$ENDIF}
|
|
DEBUG,NONE => {$IFDEF DEBUG} ... {$ENDIF}
|
|
This tool is most useful when you need to put several identical conditionals in a file,
|
|
You can add to the possible conditionals by selecting or typing the required symbols
|
|
in "First test" and /or "Second test" and using the Add button.
|
|
Your additons are saved in the condef.xml file in the lazarus configuration directory.
