23 | ;;; Commentary: | |
24 | ;; Smart mode for editing F90 programs in FREE FORMAT. | |
25 | ;; Knows about continuation lines, named structured statements, and other | |
26 | ;; new features in F90 including HPF (High Performance Fortran) structures. | |
27 | ;; The basic feature is to provide an accurate indentation of F90 programs. | |
28 | ;; In addition, there are many more features like automatic matching of all | |
29 | ;; end statements, an auto-fill function to break long lines, a join-lines | |
30 | ;; function which joins continued lines etc etc. | |
31 | ;; To facilitate typing, a fairly complete list of abbreviations is provided. | |
32 | ;; For example, `i is short-hand for integer (if abbrev-mode is on). | |
33 | ||
34 | ;; There are two separate features for highlighting the code. | |
35 | ;; 1) Upcasing or capitalizing of all keywords. | |
36 | ;; 2) Different colors/fonts for different structures. (X-windows) | |
37 | ;; (using either font-lock-mode or hilit19) | |
38 | ;; Automatic upcase of downcase of keywords is controlled by the parameter | |
39 | ;; f90-auto-keyword-case. | |
40 | ;; To use hilit19 it must be loaded before this file. Then the parameter | |
41 | ;; f90-auto-hilit19 determines if each line should be updated automatically. | |
42 | ||
43 | ;; The indentations of lines starting with ! is determined by the first of the | |
44 | ;; following matches: | |
45 | ;; start-string indent variable holding start-string | |
46 | ;; !!! 0 | |
47 | ;; !hpf$ 0 f90-directive-comment (default nil) | |
48 | ;; !!$ 0 f90-comment-region (default !!$) | |
49 | ;; ! as code f90-indented-comment (a regexp, default !) | |
50 | ;; default comment-column | |
51 | ;; Ex: Here is the result of three different settings of f90-indented-comment | |
52 | ;; f90-indented-comment !-indentation !!-indentation | |
53 | ;; ! as code as code | |
54 | ;; !! comment-column as code | |
55 | ;; ![^!] as code comment-column | |
56 | ;; Trailing comments are indented to comment-column with indent-for-comment M-; | |
57 | ;; f90-comment-region (C-c;) toggles insertion of f90-comment-region in region. | |
58 | ||
59 | ;; One common convention for free vs. fixed format is that free-format files | |
60 | ;; have the ending .f90 while the fixed format files have the ending .f. | |
61 | ;; To make f90-mode work, put this file in, for example, your directory | |
62 | ;; ~/lisp, and be sure that you have the following in your .emacs-file | |
63 | ;; (setq load-path (append load-path '("~/lisp"))) | |
64 | ;; (autoload 'f90-mode "f90" | |
65 | ;; "Major mode for editing Fortran 90 code in free format." t) | |
66 | ;; (setq auto-mode-alist (append auto-mode-alist | |
67 | ;; (list '("\\.f90$" . f90-mode)))) | |
68 | ;; Once you have entered f90-mode, you may get more info by using | |
69 | ;; the command describe-mode (C-h m). For online help describing various | |
70 | ;; functions use C-h f <Name of function you want described> | |
71 | ||
72 | ;; To customize the f90-mode for your taste, use, for example: | |
73 | ;; (you don't have to specify values for all the parameters below) | |
74 | ;;(setq f90-mode-hook | |
75 | ;; '(lambda () (setq f90-do-indent 3 | |
76 | ;; f90-if-indent 3 | |
77 | ;; f90-type-indent 3 | |

95 | ;; (f90-change-keywords f90-auto-keyword-case)) | |
96 | ;; )) | |
97 | ;; in your .emacs file (the shown values are the defaults). You can also | |
98 | ;; change the values of the lists f90-keywords etc. | |
99 | ;; The auto-fill and abbreviation minor modes are accessible from the menu, | |
100 | ;; or by using M-x f90-auto-fill-mode and M-x abbrev-mode, respectively. | |
101 | ||
102 | ;; Remarks | |
103 | ;; 1) Line numbers are by default left-justified. If f90-leave-line-no is | |
104 | ;; non-nil, the line numbers are never touched. | |
105 | ;; 2) Multi-; statements like > do i=1,20 ; j=j+i ; end do < are not handled | |
106 | ;; correctly, but I imagine them to be rare. | |
107 | ;; 3) You can use either hilit19 or font-lock-mode for your highlighting | |
108 | ;; a) To use hilit19, be sure that hilit19 is loaded before this file | |
109 | ;; b) To use font-lock-mode, nothing special is needed. | |
110 | ;; 4) For FIXED FORMAT code, use the ordinary fortran mode. | |
111 | ;; 5) This mode does not work under emacs-18.x. | |
