Full description

1 Fortran editing helpers for Emacs

1.1 Overview

You write (or work on) large, modern fortran code bases. These make heavy use of function overloading and generic interfaces. Your brain is too small to remember what all the specialisers are called. Therefore, your editor should help you. This is an attempt to do this for Emacs.

f90-interface-browser.el is a (simple-minded) parser of fortran that understands a little about generic interfaces and derived types.

1.2 External functions

f90-parse-interfaces-in-dir
Parse all the fortran files in a directory
f90-parse-all-interfaces
Parse all the fortran files in a directory and recursively in its subdirectories
f90-browse-interface-specialisers
Pop up a buffer showing all the specialisers for a particular generic interface (prompted for with completion)
f90-find-tag-interface
On a procedure call, show a list of the interfaces that match the (possibly typed) argument list. If no interface is found, this falls back to find-tag.
f90-list-in-scope-vars
List all variables in local scope. This just goes to the top of the current procedure and collects named variables, so it doesn't work with module or global scope variables or local procedures.
f90-show-type-definition
Pop up a buffer showing a derived type definition.

1.3 Customisable variables

f90-file-extensions
A list of extensions that the parser will use to decide if a file is a fortran file.

1.4 Details and caveats

The parser assumes you write fortran in the style espoused in Metcalf, Reid and Cohen. Particularly, variable declarations use a double colon to separate the type from the name list.

Here's an example of a derived type definition:

type foo
   real, allocatable, dimension(:) :: a
   integer, pointer :: b, c(:)
   type(bar) :: d
end type foo

Here's a subroutine declaration:

subroutine foo(a, b)
   integer, intent(in) :: a
   real, intent(inout), dimension(:,:) :: b
   ...
end subroutine foo

Local procedures whose names conflict with global ones will likely confuse the parser. For example:

subroutine foo(a, b)
   ...
end subroutine foo

subroutine bar(a, b)
   ...
   call subroutine foo
   ...
 contains
   subroutine foo
      ...
   end subroutine foo
end subroutine bar

Also not handled are overloaded operators, scalar precision modifiers, like integer(kind=c_int), for which the precision is just ignored, and many other of the hairier aspects of the fortran language.
