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

|
|

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