Pascal Code is more legible and neater if you follow some simple guidelines. The Z505 Pascal Coding Standard defines some basic guidelines that you may find helpful to keep your Pascal code neat and tidy looking.
Procedures are written as:
procedure TAny.DoSome(Sender: TObject; Other: Param);
instead of
procedure TAny.DoSome(Sender:TObject;Other:Param);
Procedure TAny.DoSome(Sender: TObject; Other:Param);
PROCEDURE TAny.DoSome(Sender: TObject; Other:Param);
Lower case procedure is preferred over Procedure or PROCECDURE. A space is preferred after the colon.
Functions are written as:
function TAny.DoSome(Sender: TObject; Other: Param): info;
instead of
function TAny.DoSome(Sender:TObject;Other:Param):info;
Function TAny.DoSome(Sender: TObject; Other:Param):info;
FUNCTION TAny.DoSome(Sender: TObject; Other:Param):info;
Lower case function is preferred over Function or FUNCTION. A space is preferred after the colon, akin to procedure.
The begin and end reserved words are written as:
begin
end;
end.
instead of
BEGIN
End;
END.
Indentation is as follows:
Use two spaces to indent code within begin and end.
Do not use real tabs. Two spaces is recommended over
one space.
begin
writeln('hello, how are you?');
end;
Variable declarations:
Use two spaces to indent variables under var
Do not use real tabs. Two spaces is recommended over
one space.
var
mine: string; //comments
his, //your comment
hers, //a comment
theirs: integer; //comment
num: real; //your comments
You may wish to spend time doing the following:
var
mine : string; //comments
his, //your comment
hers, //a comment
theirs : integer; //comment
num : real; //your comments
However, both the above ways are acceptable.
Below is not recommended:
var
mine :string; //comments
his,
hers,
theirs :integer;
num :real;
var
mine : string; //comments
his,
hers,
theirs : integer;
num : real;
Colons should be attached like: that.
Type, public, private, published, indentation as follows:
type
TSome = class
private
function test: integer;
procedure test6;
public
procedure test4;
procedure test5;
end;
TAnything = class
private
function testA: integer;
procedure testB;
public
procedure testC;
procedure testD;
end;
The end; lines up with the TClass. The private/public
and their functions and procedures are indented. All indentation is by two
spaces.
The else statement:
coming soon
The and statements:
coming soon
The repeat statements:
coming soon
The for and while statements:
