Overview
IDE directives are similar to compiler directives as they are special comments in the source. They use the curly brackets and the percentage sign. For example:
{%H-}For the compiler they are simple comments and ignored. The IDE uses these directives to store source specific information independent of project and session.
Hide one hint, note or warning
To hide one single hint, note or warning you can use the following IDE directive:
procedure DoSomething({%H-}NotUsed: char);
begin
end;Hint: You can right click on a hint in the message window and click on "hide message via directive" to insert the directive automatically.
This feature exists since 0.9.29.
File encoding
You can specify what encoding the IDE should use for a source file by adding a BOM or an encoding directive at the very start of a source file:
{%encoding CP1250}See the unit lcl/lconvencoding.pas for all possible values.
Run/Build file
See Configure Build File.
Reading / finding IDE directives
The codetools unit basiccodetools contains several functions for reading IDE directives:
