29 | ;;; Commentary: | |
30 | ;; | |
31 | ||
32 | ;; This is Version 4.0 of the EDT Emulation for Emacs 19 and above. | |
33 | ;; It comes with special functions which replicate nearly all of EDT's | |
34 | ;; keypad mode behavior. It sets up default keypad and function key | |
35 | ;; bindings which closely match those found in EDT. Support is | |
36 | ;; provided so that users may reconfigure most keypad and function key | |
37 | ;; bindings to their own liking. | |
38 | ||
39 | ;; NOTE: Version 4.0 contains several enhancements. See the | |
40 | ;; Enhancement section below for the details. | |
41 | ||
42 | ;; Getting Started: | |
43 | ||
44 | ;; To start the EDT Emulation, first start Emacs and then enter | |
45 | ;; | |
46 | ;; M-x edt-emulation-on | |
47 | ;; | |
48 | ;; to begin the emulation. After initialization is complete, the | |
49 | ;; following message will appear below the status line informing you | |
50 | ;; that the emulation has been enabled: "Default EDT keymap active". | |
51 | ||
52 | ;; You can have the EDT Emulation start up automatically, each time | |
53 | ;; you initiate a GNU Emacs session, by adding the following line to | |
54 | ;; your .emacs file: | |
55 | ;; | |
56 | ;; (add-hook term-setup-hook 'edt-emulation-on) | |
57 | ||
58 | ;; IMPORTANT: Be sure to read the file, edt-user.doc, located in the | |
59 | ;; Emacs "etc" directory. It contains very helpful user information. | |
60 | ||
61 | ;; The EDT emulation consists of the following files: | |
62 | ;; | |
63 | ;; edt-user.doc - User Instructions and Sample Customization File | |
64 | ;; edt.el - EDT Emulation Functions and Default Configuration | |
65 | ;; edt-lk201.el - Built-in support for DEC LK-201 Keyboards | |
66 | ;; edt-vt100.el - Built-in support for DEC VT-100 (and above) terminals | |
67 | ;; edt-pc.el - Built-in support for PC 101 Keyboards under MS-DOS | |
68 | ;; edt-mapper.el - Create an EDT LK-201 Map File for Keyboards Without | |
69 | ;; Built-in Support | |
70 | ||
71 | ;; Enhancements: | |
72 | ||
73 | ;; Version 4.0 contains the following enhancements: | |
74 | ||
75 | ;; 1. Scroll margins at the top and bottom of the window are now | |
76 | ;; supported. (The design was copied from tpu-extras.el.) By | |
77 | ;; default, this feature is enabled, with the top margin set to | |
78 | ;; 10% of the window and the bottom margin set to 15% of the | |
79 | ;; window. To change these settings, you can invoke the function | |
80 | ;; edt-set-scroll-margins in your .emacs file. For example, the | |
81 | ;; following line | |
82 | ;; | |
83 | ;; (edt-set-scroll-margins "20%" "25%") | |
84 | ;; | |
85 | ;; sets the top margin to 20% of the window and the bottom margin | |
86 | ;; to 25% of the window. To disable this feature, set each | |
87 | ;; margin to 0%. You can also invoke edt-set-scroll-margins | |
88 | ;; interactively while EDT Emulation is active to change the | |
89 | ;; settings for that session. | |
90 | ;; | |
91 | ;; NOTE: Another way to set the scroll margins is to use the | |
92 | ;; Emacs customization feature (not available in Emacs 19) to set | |
93 | ;; the following two variables directly: | |
94 | ;; | |
95 | ;; edt-top-scroll-margin and edt-bottom-scroll-margin | |
96 | ;; | |
97 | ;; Enter the Emacs `customize' command. First select the Editing | |
98 | ;; group and then select the Emulations group. Finally, select | |
99 | ;; the Edt group and follow the directions. | |
100 | ;; | |
101 | ;; 2. The SUBS command is now supported and bound to GOLD-Enter by | |
102 | ;; default. (This design was copied from tpu-edt.el.) Note, in | |
103 | ;; earlier versions of EDT Emulation, GOLD-Enter was assigned to | |
104 | ;; the Emacs function `query-replace'. The binding of | |
105 | ;; `query-replace' has been moved to GOLD-/. If you prefer to | |
106 | ;; restore `query-replace' to GOLD-Enter, then use an EDT user | |
107 | ;; customization file, edt-user.el, to do this. See edt-user.doc | |
108 | ;; for details. | |
109 | ||
110 | ;; 3. EDT Emulation now also works in XEmacs, including the | |
111 | ;; highlighting of selected text. | |
112 | ||
113 | ;; 4. If you access a workstation using an X Server, observe that | |
114 | ;; the initialization file generated by edt-mapper.el will now | |
115 | ;; contain the name of the X Server vendor. This is a | |
116 | ;; convenience for those who have access to their Unix account | |
117 | ;; from more than one type of X Server. Since different X | |
118 | ;; Servers typically require different EDT emulation | |
119 | ;; initialization files, edt-mapper.el will now generate these | |
120 | ;; different initialization files and save them with different | |
121 | ;; names. Then, the correct initialization file for the | |
122 | ;; particular X server in use is loaded correctly automatically. | |
123 | ||
124 | ;; 5. Also, edt-mapper.el is now capable of binding an ASCII key | |
125 | ;; sequence, providing the ASCII key sequence prefix is already | |
126 | ;; known by Emacs to be a prefix. As a result of providing this | |
127 | ;; support, some terminal/keyboard/window system configurations, | |
128 | ;; which don't have a complete set of sensible function key | |
129 | ;; bindings built into Emacs in `function-key-map', can still be | |
130 | ;; configured for use with EDT Emulation. (Note: In a few rare | |
131 | ;; circumstances this does not work properly. In particular, it | |
132 | ;; does not work if a subset of the leading ASCII characters in a | |
133 | ;; key sequence are recognized by Emacs as having an existing | |
134 | ;; binding. For example, if the keypad 7 (KP-7) key generates | |
135 | ;; the sequence \"<ESC>Ow\" and \"<ESC>O\" is already bound to a | |
136 | ;; function, pressing KP-7 when told to do so by edt-mapper.el | |
137 | ;; will result in edt-mapper.el incorrectly mapping \"<ESC>O\" to | |
138 | ;; KP-7 and \"w\" to KP-8. If something like this happens to | |
139 | ;; you, it is probably a bug in the support for your keyboard | |
140 | ;; within Emacs OR a bug in the Unix termcap/terminfo support for | |
141 | ;; your terminal OR a bug in the terminal emulation software you | |
142 | ;; are using.) | |
143 | ||
144 | ;; 6. The edt-quit function (bound to GOLD-q by default) has been | |
145 | ;; modified to warn the user when file-related buffer | |
146 | ;; modifications exist. It now cautions the user that those | |
147 | ;; modifications will be lost if the user quits without saving | |
148 | ;; those buffers. | |

2099 | Ack!! You're running the Enhanced EDT Emulation without loading an |

2102 | without any of your own customizations found in your .emacs file, etc. | |
2103 | The reason for this is that some user customizations confuse edt-mapper. | |
2104 | You can do this by quitting Emacs and then invoking Emacs again as | |
