28 | ;; Major mode for editing F90 programs in FREE FORMAT. |
29 | ;; The minor language revision F95 is also supported (with font-locking). | |
30 | ||
034a9d40 | 31 | ;; Knows about continuation lines, named structured statements, and other |
87ee2359 GM |
32 | ;; features in F90 including HPF (High Performance Fortran) structures. |
33 | ;; The basic feature provides accurate indentation of F90 programs. | |
034a9d40 RS |
34 | ;; In addition, there are many more features like automatic matching of all |
35 | ;; end statements, an auto-fill function to break long lines, a join-lines | |
87ee2359 GM |
36 | ;; function which joins continued lines, etc. |
37 | ||
38 | ;; To facilitate typing, a fairly complete list of abbreviations is provided. | |
39 | ;; All abbreviations begin with the backquote character "`" | |
40 | ;; (this requires modification of the syntax-table). | |
41 | ;; For example, `i expands to integer (if abbrev-mode is on). | |
034a9d40 | 42 | |
87ee2359 | 43 | ;; There are two separate features for altering the appearance of code: |
034a9d40 | 44 | ;; 1) Upcasing or capitalizing of all keywords. |
87ee2359 GM |
45 | ;; 2) Colors/fonts using font-lock-mode. |
46 | ;; Automatic upcase or downcase of keywords is controlled by the variable | |
47 | ;; f90-auto-keyword-case. | |
034a9d40 RS |
48 | |
49 | ;; The indentations of lines starting with ! is determined by the first of the | |
87ee2359 | 50 | ;; following matches (values in the left column are the defaults): |
ee30478d KH |
51 | |
52 | ;; start-string/regexp indent variable holding start-string/regexp | |
53 | ;; !!! 0 | |
54 | ;; !hpf\\$ (re) 0 f90-directive-comment-re | |
55 | ;; !!$ 0 f90-comment-region | |
56 | ;; ! (re) as code f90-indented-comment-re | |
57 | ;; default comment-column | |
58 | ||
59 | ;; Ex: Here is the result of 3 different settings of f90-indented-comment-re | |
60 | ;; f90-indented-comment-re !-indentation !!-indentation | |
61 | ;; ! as code as code | |
62 | ;; !! comment-column as code | |
63 | ;; ![^!] as code comment-column | |
87ee2359 GM |
64 | ;; Trailing comments are indented to comment-column with indent-for-comment. |
65 | ;; The function f90-comment-region toggles insertion of | |
66 | ;; the variable f90-comment-region in every line of the region. | |
034a9d40 RS |
67 | |
68 | ;; One common convention for free vs. fixed format is that free-format files | |
69658465 | 69 | ;; have the ending .f90 or .f95 while fixed format files have the ending .f. |
87ee2359 GM |
70 | ;; Emacs automatically loads Fortran files in the appropriate mode based |
71 | ;; on extension. You can modify this by adjusting the variable auto-mode-alist. | |
72 | ;; For example: | |
73 | ;; (add-to-list 'auto-mode-alist '("\\.f\\'" . f90-mode)) | |
74 | ||
034a9d40 | 75 | ;; Once you have entered f90-mode, you may get more info by using |
69658465 | 76 | ;; the command describe-mode (C-h m). For online help use |
87ee2359 GM |
77 | ;; C-h f <Name of function you want described>, or |
78 | ;; C-h v <Name of variable you want described>. | |
034a9d40 | 79 | |
87ee2359 GM |
80 | ;; To customize f90-mode for your taste, use, for example: |
81 | ;; (you don't have to specify values for all the parameters below) | |
82 | ;; | |
d2d15846 | 83 | ;;(add-hook 'f90-mode-hook |

034a9d40 RS |
114 | |
115 | ;; Remarks | |
116 | ;; 1) Line numbers are by default left-justified. If f90-leave-line-no is | |
117 | ;; non-nil, the line numbers are never touched. | |
87ee2359 | 118 | ;; 2) Multi-; statements like "do i=1,20 ; j=j+i ; end do" are not handled |
034a9d40 | 119 | ;; correctly, but I imagine them to be rare. |
ee30478d | 120 | ;; 3) Regexps for hilit19 are no longer supported. |
87ee2359 | 121 | ;; 4) For FIXED FORMAT code, use fortran mode. |
034a9d40 | 122 | ;; 5) This mode does not work under emacs-18.x. |
72e80cad KH |
123 | ;; 6) Preprocessor directives, i.e., lines starting with # are left-justified |
124 | ;; and are untouched by all case-changing commands. There is, at present, no | |
125 | ;; mechanism for treating multi-line directives (continued by \ ). | |
ee30478d KH |
126 | ;; 7) f77 do-loops do 10 i=.. ; ; 10 continue are not correctly indented. |
127 | ;; You are urged to use f90-do loops (with labels if you wish). | |
c80718cc | 128 | ;; 8) The highlighting mode under XEmacs is not as complete as under Emacs. |
