How to Document A Fortran Enum With Doxygen?

To document a Fortran enum with Doxygen, you can use comments in your code to describe the purpose of each enum value. Doxygen supports documenting enums in Fortran by using the !> syntax before each enum value. This syntax allows you to provide a description for each value that will be included in the generated documentation. You can also use the enum command in Doxygen to provide an overall description of the enum type. By adding appropriate comments to your code, you can effectively document enums in Fortran using Doxygen.

What is the Doxygen command to document a Fortran enum?

To document a Fortran enum using Doxygen, you can use the following command:

1
2
3
4
5
6

!> \enum EnumName
!> Description of the enum values.
!> \var EnumValue1
!> Description of EnumValue1
!> \var EnumValue2
!> Description of EnumValue2

Replace EnumName, EnumValue1, and EnumValue2 with your enum and enum values, and provide the descriptions accordingly.

What is the importance of documenting enums in Fortran programs with Doxygen for code maintenance?

Documenting enums in Fortran programs with Doxygen is important for code maintenance for several reasons:

1. Improves code readability: Documenting enums with Doxygen provides a clear and concise description of the enum values, making it easier for other developers to understand the purpose and usage of each value.
2. Facilitates code navigation: By documenting enums with Doxygen, developers can quickly navigate through the codebase to find specific enum values and their descriptions, saving time and effort.
3. Enhances code documentation: Using Doxygen to document enums in Fortran programs allows developers to generate comprehensive documentation for the entire codebase, making it easier for future developers to understand and maintain the code.
4. Promotes code consistency: Documenting enums with Doxygen encourages developers to follow consistent naming conventions and coding practices, which can improve the overall quality and maintainability of the codebase.
5. Simplifies code maintenance: Well-documented enums help developers easily identify and update enum values when necessary, reducing the risk of introducing errors and making the codebase more robust and maintainable in the long run.

How to add examples of how to use each enum value in the Doxygen documentation for Fortran?

To add examples of how to use each enum value in the Doxygen documentation for Fortran, you can follow these steps:

1. Define the enum in your Fortran code with the desired values and write a brief description of each enum value.

1
2
3
4

!> Enum defining different colors
ENUM, BIND(C)
    ENUMERATOR :: RED = 1, YELLOW, BLUE
END ENUM

1. Add examples of how to use each enum value in your code, making sure to include comments explaining the usage.

5

!> Example of using the RED color
!> @code
!>   ! Set color to RED
!>   color = RED
!> @endcode

1. Use Doxygen’s markup tags to document the examples and provide further details on how to use each enum value.

!> @details
!> This subroutine sets the color using the provided enum value.
!>
SUBROUTINE SetColor(color)
  INTEGER, INTENT(IN) :: color

  SELECT CASE(color)
    CASE(RED)
      PRINT *, "Setting color to RED"
    CASE(YELLOW)
      PRINT *, "Setting color to YELLOW"
    CASE(BLUE)
      PRINT *, "Setting color to BLUE"
    CASE DEFAULT
      PRINT *, "Unknown color"
  END SELECT

END SUBROUTINE SetColor

By following these steps, you can effectively document each enum value and provide examples of how to use them in your Fortran code for Doxygen documentation.

How to provide documentation for each enum value in Fortran using Doxygen?

To provide documentation for each enum value in Fortran using Doxygen, you can follow these steps:

1. Begin by defining your enum type in Fortran. For example:

1
2
3
4

!> Enum defining the days of the week
enum, bind(c)
  enumerator :: Monday = 1, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday
end enum

1. Next, you can provide documentation for each enum value using Doxygen-style comments:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16

18
19
20

!> @brief Enum representing Monday
integer, parameter :: Monday = 1

!> @brief Enum representing Tuesday
integer, parameter :: Tuesday = 2

!> @brief Enum representing Wednesday
integer, parameter :: Wednesday = 3

!> @brief Enum representing Thursday
integer, parameter :: Thursday = 4

!> @brief Enum representing Friday
integer, parameter :: Friday = 5

!> @brief Enum representing Saturday
integer, parameter :: Saturday = 6

!> @brief Enum representing Sunday
integer, parameter :: Sunday = 7

1. Finally, run Doxygen on your Fortran code to generate the documentation. Make sure to configure Doxygen to recognize Fortran code and to include comments in the documentation.

By following these steps, you can provide documentation for each enum value in Fortran using Doxygen. This will help make your code more readable and understandable for other developers.

What is the syntax for adding comments to a Fortran enum in Doxygen?

To add comments to a Fortran enum in Doxygen, you can use the following syntax:

1
2
3
4
5
6

!> Description of the enum
enum, bind(c)
  enumerator1 = 1, !< Description of enumerator1
  enumerator2 = 2, !< Description of enumerator2
  enumerator3 = 3  !< Description of enumerator3
end enum

In this example, !> is used to provide a description for the enum, and !< is used to provide a description for each enumerator. These comments will be picked up by Doxygen when generating documentation for your Fortran code.
