Minimap: a miniature representation of your code in a thin column near to or replacing the scrollbar. Pascal Expert main task is to make a static code analysis. It only needs the source code, unlike other similar tools that perform an analysis of the running program. Pascal Expert will help you better understand your code and support you in producing code of higher quality, consistency, and reliability.
It will point out possible issues and errors in your code. Pascal Expert is a subset of standalone static code analyzer Pascal Analyzer. Pascal Expert displays the same results as Pascal Analyzer, but integrated in the Delphi IDE, which makes it an ideal tool when working with code, as it lets you find problems earlier, and fix them at once. Pascal Expert parses your source code in the same way as the compiler. This tab page is normally located at the bottom of the window.
Suggestions are highlighted as the user continues typing. If the user presses Enter, the highlighted selection is entered into the editor and the cursor is placed at the end of the entry. The unit file "Project. NOTE: This constant is updated every compile to reflect the current compile date and time. Instructions: Drop this component on the TForm, then set the project path. Save the project, then exit Delphi.
The next time the project is opened in Delphi, the unit file "Project. Then each time you run the program from inside Delphi, the unit file will be updated with the current date, time and the build number. Platforms: D5 , D6.

These comments are generally useful only during code development, as their primary benefit is that they allow nesting of comments, as long as the nest level is less than 2. Object Pascal doesn't support nesting comments of the same type within each other, so really there is only one level of comment nesting: curly inside of starparen, and starparen inside of curly.
As long as you don't nest them, any other standard Pascal comments between comments of this type will be ignored. As a result, you can use this syntax to comment out a large chunk of code that is full of mixed code and comments:. In this example, the entire Button1Click method is commented out, including any of the subcomments found between the procedure's begin.. A single-line comment or comment group should always be preceded by a blank line, unless it is the first line in a block.
If the comment applies to a group of several statements, then the comment or comment group should also be followed by a blank line. If it applies only to the next statement which may be a compound statement , then do not follow it with a blank line. Single-line comments can also follow the code they reference. These comments, sometimes referred to as trailing comments, appear on the same line as the code they describe. They should have at least one space-character separating them from the code they reference.
If more than one trailing comment appears in a block of code, they should all be aligned to the same column. Avoid commenting every line of executable code with a trailing comment. It is usually best to limit the comments inside the begin..
Longer comments can appear in a block comment before the method or function declaration. Except for code inserted by the IDE, the scoping directives for a class should be declared in the following order:. There are four access levels for class members in Object Pascal: published, public, protected, and private -- in order of decreasing accessibility.
By default, the access level is published. In general, a member should be given the lowest access level which is appropriate for the member. For example, a member which is only accessed by classes in the same unit should be set to private access. Also, declaring a lower access level will often give the compiler increased opportunities for optimization. On the other hand, use of private makes it difficult to extend the class by sub-classing.
If there is reason to believe the class might be sub-classed in the future, then members that might be needed by sub-classes should be declared protected instead of private, and the properties used to access private data should be given protected status. You should never allow public access to data. Data should always be declared in the private section, and any public access should be via getter and setter methods, or properties. Methods should be arranged alphabetically.
It is correct either to place your constructors and destructors at the head of this list in the public section, or to arrange them in alphabetical order within the public section. If there is more than one constructor, and if you choose to give them all the same name, then sort them lexically by formal parameter list, with constructors having more parameters always coming after those with fewer parameters.
This implies that a constructor with no arguments if it exists is always the first one. An interface declaration should be indented two spaces. The body of the interface is indented by the standard indentation of four spaces. The closing end statement should also be indented two characters. There should be a semi-colon following the closing end statement. All interface methods are inherently public and abstract; do not explicitly include these keywords in the declaration of an interface method.
The declaration styles of interface properties and methods are identical to the styles for class properties and methods. Local variables should have Camel Caps, that is, they should start with a capital letter, and have capital letters for the beginning of each embedded word. Do not preface variable names with an F, as that convention is reserved for Fields in a class declaration:. This practice is discouraged in class declarations. There you should place each field on a separate line, along with its type.
Contents 1. At least one blank line should separate each of these elements. The word unit is a reserved word, so it should be in lower case. The name of the unit should be in mixed upper and lowercase, and must be the same as the name used by the operating system's file system. Add the names of the units, following the capitalization conventions used in the declaration found inside the units: uses MyUnit; Each unit must be separated from its neighbor by a comma, and the last unit should have a semicolon after it: uses Windows, SysUtils, Classes, Graphics, Controls, Forms, TypInfo; It is correct to start the uses clause on the next line, as in the previous example, or you may start the list of units on the same line: uses Windows, SysUtils, Classes, Graphics, Controls, Forms, TypInfo; You may format the list of units in your uses clause so that they wrap just shy of 80 characters, or so that one unit appears on each line.
Naming Conventions MyIdentifier MyFTPClass The major exception to this rule is in the case of header translations, which should always follow the conventions used in the header. Start with a capital letter, and capitalize the first letter of any subsequent word in the name, as well as any letters that are part of an acronym. All other characters in the name are lower case.
Do not use underscores to separate words. Note that this is identical to the naming convention for non-constant fields; however it should always be easy to distinguish the two from context. Method names should be imperative verbs or verb phrases. Examples: GetHeight, SetHeight A method to test some boolean property of the class should be called IsVisible, where Visible is the name of the property.
Examples: IsResizable, IsVisible 3. A blank line should also be used in the following places: After the copyright block comment, package declaration, and import section. Between class declarations. Between method declarations. Before or after a.
Between a unary operator and its operand. Between a cast and the expression being cast. After an opening parenthesis or before a closing parenthesis. After an opening square bracket [ or before a closing square bracket ]. Before a semicolon. Examples of correct usage: function TMyClass. It is helpful to place comments before a class declaration. It is helpful to place comments before some method declarations.
Avoid putting any information into comments that is likely to become out of date. Avoid enclosing comments in boxes drawn with asterisks or other special typography. Temporary comments that are expected to be changed or removed later should be marked with the special tag "??? Ideally, all temporary comments should have been removed by the time a program is ready to be shipped. MySort; 5. The property editor is created based on the type of the property being edited as determined by the types registered by GetXxxValue Gets the value of the first property in the Properties property.
SetXxxValue Sets the value of all the properties in the Properties property. Block comments used to describe a method should appear before the method declaration. MyMethod This routine allows you to execute code. Open; Single-line comments can also follow the code they reference. Classes The body of a class declaration should be organized in the following order: Field declarations Method declarations Property declarations The fields, properties and methods in your class should be arranged alphabetically by name.
There are no fields in an interface declaration. Properties, however, are allowed. Except as otherwise noted, interface declarations follow the same style guidelines as classes. Do not preface variable names with an F, as that convention is reserved for Fields in a class declaration: var MyData: Integer; MyString: string; You may declare multiple identifiers of the same type on a single line: var ArraySize, ArrayCount: Integer; This practice is discouraged in class declarations.
A simple statement contains a single semicolon. If you need to wrap the statement, indent the second line two spaces in from the previous line: Statements are one or more lines of code followed by a semicolon. Simple statements have one semicolon, while compound statements have more than one semicolon and therefore consist of multiple simple statements. The body of an interface declaration should be organized in the following order: If possible, a method declaration should appear on one line.
Place single line comments at the same indentation level as the code that follows it. You can group single-line comments to form a larger comment. Object Pascal supports two types of block comments. The Delphi team prefers to keep comments of this type as spare and simple as possible. For instance, you should avoid using asterisks to create patterns or lines inside your comments.
Instead, make use of white space to break your comments up, much as you would in a word processing document. The words in your comments should start on the same line as the first curly brace, as shown in this excerpt from DsgnIntf. Some general guidelines for comment usage include: Lines should be limited to 80 columns. Lines longer than 80 columns should be broken into one or more continuation lines, as needed.
All the continuation lines should be aligned and indented from the first line of the statement, and indented two characters. Always place begin statements on their own line. You should always indent two spaces for all indentation levels. In other words, the first level of indentation is two spaces, the second level four spaces, the third level 6 spaces, etc. Never use tab characters.
