28 | ;; Smart mode for editing F90 programs in FREE FORMAT. |
29 | ;; Knows about continuation lines, named structured statements, and other | |
30 | ;; new features in F90 including HPF (High Performance Fortran) structures. | |
31 | ;; The basic feature is to provide an accurate indentation of F90 programs. | |
32 | ;; In addition, there are many more features like automatic matching of all | |
33 | ;; end statements, an auto-fill function to break long lines, a join-lines | |
34 | ;; function which joins continued lines etc etc. | |
35 | ;; To facilitate typing, a fairly complete list of abbreviations is provided. | |
36 | ;; For example, `i is short-hand for integer (if abbrev-mode is on). | |
37 | ||
38 | ;; There are two separate features for highlighting the code. | |
39 | ;; 1) Upcasing or capitalizing of all keywords. | |
ee30478d | 40 | ;; 2) Colors/fonts using font-lock-mode. (only when using X-windows) |
034a9d40 RS |
41 | ;; Automatic upcase of downcase of keywords is controlled by the parameter |
42 | ;; f90-auto-keyword-case. | |
034a9d40 RS |
43 | |
44 | ;; The indentations of lines starting with ! is determined by the first of the | |
ee30478d KH |
45 | ;; following matches (the values in the left column are the default values): |
46 | ||
47 | ;; start-string/regexp indent variable holding start-string/regexp | |
48 | ;; !!! 0 | |
49 | ;; !hpf\\$ (re) 0 f90-directive-comment-re | |
50 | ;; !!$ 0 f90-comment-region | |
51 | ;; ! (re) as code f90-indented-comment-re | |
52 | ;; default comment-column | |
53 | ||
54 | ;; Ex: Here is the result of 3 different settings of f90-indented-comment-re | |
55 | ;; f90-indented-comment-re !-indentation !!-indentation | |
56 | ;; ! as code as code | |
57 | ;; !! comment-column as code | |
58 | ;; ![^!] as code comment-column | |
034a9d40 RS |
59 | ;; Trailing comments are indented to comment-column with indent-for-comment M-; |
60 | ;; f90-comment-region (C-c;) toggles insertion of f90-comment-region in region. | |
61 | ||
62 | ;; One common convention for free vs. fixed format is that free-format files | |
63 | ;; have the ending .f90 while the fixed format files have the ending .f. | |
64 | ;; To make f90-mode work, put this file in, for example, your directory | |
65 | ;; ~/lisp, and be sure that you have the following in your .emacs-file | |
66 | ;; (setq load-path (append load-path '("~/lisp"))) | |
67 | ;; (autoload 'f90-mode "f90" | |
68 | ;; "Major mode for editing Fortran 90 code in free format." t) | |
69 | ;; (setq auto-mode-alist (append auto-mode-alist | |
70 | ;; (list '("\\.f90$" . f90-mode)))) | |
71 | ;; Once you have entered f90-mode, you may get more info by using | |
72 | ;; the command describe-mode (C-h m). For online help describing various | |
73 | ;; functions use C-h f <Name of function you want described> | |
74 | ||
75 | ;; To customize the f90-mode for your taste, use, for example: | |
76 | ;; (you don't have to specify values for all the parameters below) | |
77 | ;;(setq f90-mode-hook | |
78 | ;; '(lambda () (setq f90-do-indent 3 | |

107 | ;; Remarks | |
108 | ;; 1) Line numbers are by default left-justified. If f90-leave-line-no is | |
109 | ;; non-nil, the line numbers are never touched. | |
110 | ;; 2) Multi-; statements like > do i=1,20 ; j=j+i ; end do < are not handled | |
111 | ;; correctly, but I imagine them to be rare. | |
ee30478d | 112 | ;; 3) Regexps for hilit19 are no longer supported. |
034a9d40 RS |
113 | ;; 4) For FIXED FORMAT code, use the ordinary fortran mode. |
114 | ;; 5) This mode does not work under emacs-18.x. | |
72e80cad KH |
115 | ;; 6) Preprocessor directives, i.e., lines starting with # are left-justified |
116 | ;; and are untouched by all case-changing commands. There is, at present, no | |
117 | ;; mechanism for treating multi-line directives (continued by \ ). | |
ee30478d KH |
118 | ;; 7) f77 do-loops do 10 i=.. ; ; 10 continue are not correctly indented. |
119 | ;; You are urged to use f90-do loops (with labels if you wish). | |
