||
;;; Commentary:
|
||
|
||
;; Smart mode for editing F90 programs in FREE FORMAT.
|
||
;; Knows about continuation lines, named structured statements, and other
|
||
;; new features in F90 including HPF (High Performance Fortran) structures.
|
||
;; The basic feature is to provide an accurate indentation of F90 programs.
|
||
;; 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
|
||
;; function which joins continued lines etc etc.
|
||
;; To facilitate typing, a fairly complete list of abbreviations is provided.
|
||
;; For example, `i is short-hand for integer (if abbrev-mode is on).
|
||
|
||
;; There are two separate features for highlighting the code.
|
||
;; 1) Upcasing or capitalizing of all keywords.
|
||
;; 2) Colors/fonts using font-lock-mode. (only when using X-windows)
|
||
;; Automatic upcase of downcase of keywords is controlled by the parameter
|
||
;; f90-auto-keyword-case.
|
||
|
||
;; The indentations of lines starting with ! is determined by the first of the
|
||
;; following matches (the values in the left column are the default values):
|
||
|
||
;; start-string/regexp indent variable holding start-string/regexp
|
||
;; !!! 0
|
||
;; !hpf\\$ (re) 0 f90-directive-comment-re
|
||
;; !!$ 0 f90-comment-region
|
||
;; ! (re) as code f90-indented-comment-re
|
||
;; default comment-column
|
||
|
||
;; Ex: Here is the result of 3 different settings of f90-indented-comment-re
|
||
;; f90-indented-comment-re !-indentation !!-indentation
|
||
;; ! as code as code
|
||
;; !! comment-column as code
|
||
;; ![^!] as code comment-column
|
||
;; Trailing comments are indented to comment-column with indent-for-comment M-;
|
||
;; f90-comment-region (C-c;) toggles insertion of f90-comment-region in region.
|
||
|
||
;; One common convention for free vs. fixed format is that free-format files
|
||
;; have the ending .f90 while the fixed format files have the ending .f.
|
||
;; To make f90-mode work, put this file in, for example, your directory
|
||
;; ~/lisp, and be sure that you have the following in your .emacs-file
|
||
;; (setq load-path (append load-path '("~/lisp")))
|
||
;; (autoload 'f90-mode "f90"
|
||
;; "Major mode for editing Fortran 90 code in free format." t)
|
||
;; (setq auto-mode-alist (append auto-mode-alist
|
||
;; (list '("\\.f90$" . f90-mode))))
|
||
;; Once you have entered f90-mode, you may get more info by using
|
||
;; the command describe-mode (C-h m). For online help describing various
|
||
;; functions use C-h f <Name of function you want described>
|
||
|
||
;; To customize the f90-mode for your taste, use, for example:
|
||
;; (you don't have to specify values for all the parameters below)
|
||
;;(add-hook 'f90-mode-hook
|
||
;; '(lambda () (setq f90-do-indent 3

|

|
||
;; (f90-change-keywords f90-auto-keyword-case))
|
||
;; ))
|
||
;; in your .emacs file (the shown values are the defaults). You can also
|
||
;; change the values of the lists f90-keywords etc.
|
||
;; The auto-fill and abbreviation minor modes are accessible from the menu,
|
||
;; or by using M-x auto-fill-mode and M-x abbrev-mode, respectively.
|
||
|
||
;; Remarks
|
||
;; 1) Line numbers are by default left-justified. If f90-leave-line-no is
|
||
;; non-nil, the line numbers are never touched.
|
||
;; 2) Multi-; statements like > do i=1,20 ; j=j+i ; end do < are not handled
|
||
;; correctly, but I imagine them to be rare.
|
||
;; 3) Regexps for hilit19 are no longer supported.
|
||
;; 4) For FIXED FORMAT code, use the ordinary fortran mode.
|
||
;; 5) This mode does not work under emacs-18.x.
|
||
;; 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 \ ).
|
||
;; 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).
|
||
;; 8) The highlighting mode under XEmacs is not as complete as under Emacs.
