;; Major mode for editing F90 programs in FREE FORMAT.
|
|
|
|
|
|
;; The minor language revision F95 is also supported (with font-locking).

;; Knows about continuation lines, named structured statements, and other
|
2002-04-25 21:55:39 +00:00
|
|
|
|
;; features in F90 including HPF (High Performance Fortran) structures.
|
|
|
|
|
|
;; The basic feature provides accurate indentation of F90 programs.
|
1995-01-31 06:13:47 +00:00
|
|
|
|
;; In addition, there are many more features like automatic matching of all
|
|
|
|
|
|
;; end statements, an auto-fill function to break long lines, a join-lines
|
2002-04-25 21:55:39 +00:00
|
|
|
|
;; function which joins continued lines, etc.
|
|
|
|
|
|
|
|
|
|
|
|
;; To facilitate typing, a fairly complete list of abbreviations is provided.
|
|
|
|
|
|
;; All abbreviations begin with the backquote character "`"
|
|
|
|
|
|
;; (this requires modification of the syntax-table).
|
|
|
|
|
|
;; For example, `i expands to integer (if abbrev-mode is on).
|

2002-04-25 21:55:39 +00:00
|

|
|
;; There are two separate features for altering the appearance of code:
|
1995-01-31 06:13:47 +00:00
|
|
|
|
;; 1) Upcasing or capitalizing of all keywords.
|
2002-04-25 21:55:39 +00:00
|
|
|
|
;; 2) Colors/fonts using font-lock-mode.
|
|
|
|
|
|
;; Automatic upcase or downcase of keywords is controlled by the variable
|
|
|
|
|
|
;; f90-auto-keyword-case.

;; The indentations of lines starting with ! is determined by the first of the
|
2002-04-25 21:55:39 +00:00
|
|
|
|
;; following matches (values in the left column are the defaults):

|
2002-04-25 21:55:39 +00:00
|
|
|
|
;; Trailing comments are indented to comment-column with indent-for-comment.
|
|
|
|
|
|
;; The function f90-comment-region toggles insertion of
|
|
|
|
|
|
;; the variable f90-comment-region in every line of the region.

|
|

|
|
;; One common convention for free vs. fixed format is that free-format files
|
2002-04-29 23:24:28 +00:00
|
|
|
|
;; have the ending .f90 or .f95 while fixed format files have the ending .f.

|
;; Emacs automatically loads Fortran files in the appropriate mode based
|
|
|
|
|
|
;; on extension. You can modify this by adjusting the variable auto-mode-alist.
|
|
|
|
|
|
;; For example:
|
|
|
|
|
|
;; (add-to-list 'auto-mode-alist '("\\.f\\'" . f90-mode))

|
2002-04-29 23:24:28 +00:00
|
|
|
|
;; the command describe-mode (C-h m). For online help use
|
2002-04-25 21:55:39 +00:00

;; non-nil, the line numbers are never touched.
|
2002-04-25 21:55:39 +00:00
|
|
|
|
;; 2) Multi-; statements like "do i=1,20 ; j=j+i ; end do" are not handled
|
1995-01-31 06:13:47 +00:00
|
|
|
|
;; correctly, but I imagine them to be rare.
|
1995-09-22 21:31:45 +00:00
|
|
|
|
;; 3) Regexps for hilit19 are no longer supported.
|
2002-04-25 21:55:39 +00:00
|
|
|
|
;; 4) For FIXED FORMAT code, use fortran mode.
|
1995-01-31 06:13:47 +00:00
|
|
|
|
;; 5) This mode does not work under emacs-18.x.
|
1995-04-20 17:23:29 +00:00
|
|
|
|
;; 6) Preprocessor directives, i.e., lines starting with # are left-justified
|
|
|
|
|
|
;; and are untouched by all case-changing commands. There is, at present, no
|
|
|
|
|
|
;; mechanism for treating multi-line directives (continued by \ ).
|
1995-09-22 21:31:45 +00:00
|
|
|
|
;; 7) f77 do-loops do 10 i=.. ; ; 10 continue are not correctly indented.
|
|
|
|
|
|
;; You are urged to use f90-do loops (with labels if you wish).
|
1996-04-19 20:07:47 +00:00
|
|
|
|
;; 8) The highlighting mode under XEmacs is not as complete as under Emacs.
