#= parse_f95.rb - Fortran95 Parser # #== Overview # #"parse_f95.rb" parses Fortran95 files with suffixes "f90", "F90", "f95" #and "F95". Fortran95 files are expected to be conformed to Fortran95 #standards. # #== Rules # #Fundamental rules are same as that of the Ruby parser. #But comment markers are '!' not '#'. # #=== Correspondence between RDoc documentation and Fortran95 programs # #"parse_f95.rb" parses main programs, modules, subroutines, functions, #derived-types, public variables, public constants, #defined operators and defined assignments. #These components are described in items of RDoc documentation, as follows. # #Files :: Files (same as Ruby) #Classes :: Modules #Methods :: Subroutines, functions, variables, constants, derived-types, defined operators, defined assignments #Required files :: Files in which imported modules, external subroutines and external functions are defined. #Included Modules :: List of imported modules #Attributes :: List of derived-types, List of imported modules all of whose components are published again # #Components listed in 'Methods' (subroutines, functions, ...) #defined in modules are described in the item of 'Classes'. #On the other hand, components defined in main programs or #as external procedures are described in the item of 'Files'. # #=== Components parsed by default # #By default, documentation on public components (subroutines, functions, #variables, constants, derived-types, defined operators, #defined assignments) are generated. #With "--all" option, documentation on all components #are generated (almost same as the Ruby parser). # #=== Information parsed automatically # #The following information is automatically parsed. # #* Types of arguments #* Types of variables and constants #* Types of variables in the derived types, and initial values #* NAMELISTs and types of variables in them, and initial values # #Aliases by interface statement are described in the item of 'Methods'. # #Components which are imported from other modules and published again #are described in the item of 'Methods'. # #=== Format of comment blocks # #Comment blocks should be written as follows. #Comment blocks are considered to be ended when the line without '!' #appears. #The indentation is not necessary. # # ! (Top of file) # ! # ! Comment blocks for the files. # ! # !-- # ! The comment described in the part enclosed by # ! "!--" and "!++" is ignored. # !++ # ! # module hogehoge # ! # ! Comment blocks for the modules (or the programs). # ! # # private # # logical :: a ! a private variable # real, public :: b ! a public variable # integer, parameter :: c = 0 ! a public constant # # public :: c # public :: MULTI_ARRAY # public :: hoge, foo # # type MULTI_ARRAY # ! # ! Comment blocks for the derived-types. # ! # real, pointer :: var(:) =>null() ! Comments block for the variables. # integer :: num = 0 # end type MULTI_ARRAY # # contains # # subroutine hoge( in, & ! Comment blocks between continuation lines are ignored. # & out ) # ! # ! Comment blocks for the subroutines or functions # ! # character(*),intent(in):: in ! Comment blocks for the arguments. # character(*),intent(out),allocatable,target :: in # ! Comment blocks can be # ! written under Fortran statements. # # character(32) :: file ! This comment parsed as a variable in below NAMELIST. # integer :: id # # namelist /varinfo_nml/ file, id # ! # ! Comment blocks for the NAMELISTs. # ! Information about variables are described above. # ! # # .... # # end subroutine hoge # # integer function foo( in ) # ! # ! This part is considered as comment block. # # ! Comment blocks under blank lines are ignored. # ! # integer, intent(in):: inA ! This part is considered as comment block. # # ! This part is ignored. # # end function foo # # subroutine hide( in, & # & out ) !:nodoc: # ! # ! If "!:nodoc:" is described at end-of-line in subroutine # ! statement as above, the subroutine is ignored. # !
