Overview
The source editor should auto indent on pressing return/enter, on paste and when inserting auto generated code. This depends on language and user preferences. Most other editors use either a fixed set of rules or a set of options to configure the rules. This is semi automatic indentation. These options are either too simple or too complex. And they only allow one set of rules, so editing sources with different policies is difficult.
Fully automatic indentation tries to guess the rules from the surrounding code.
Examples
<Delphi> procedure Do; var
i: integer; // indent after var
begin // no indent after procedure, no indent before procedure-begin, unindent after var section
if expr then begin // no indent after then, no indent before then-begin Code; // indent after begin end; // unindent before end
end; </Delphi>
<Delphi> procedure Do; begin
if expr then begin Code; // indent after begin end; // unindent before end
end; </Delphi>
<Delphi> procedure Do; begin
if expr then begin // indent after then and unindent after then-statement Code; // no indent after begin end; // no unindent before end
end; </Delphi>
<Delphi> procedure Do; begin
if expr then
begin // indent after then
Code; // indent after begin
end; // unindent before end
end; </Delphi>
