25 | * Notes on usage of selection-coding-system and | |
26 | * next-selection-coding-system on MS Windows: | |
27 | * | |
28 | * The selection coding system variables apply only to the version of | |
29 | * the clipboard data that is closest in type, i.e. when a 16-bit | |
30 | * Unicode coding system is given, they apply to he Unicode clipboard | |
31 | * (CF_UNICODETEXT), when a well-known console codepage is given, they | |
32 | * apply to the console version of the clipboard data (CF_OEMTEXT), | |
33 | * else they apply to the normal 8-bit text clipboard (CF_TEXT). | |
34 | * | |
35 | * When pasting (getting data from the OS), the clipboard format that | |
36 | * matches the {next-}selection-coding-system is retrieved. If | |
37 | * Unicode is requested, but not available, 8-bit text (CF_TEXT) is | |
38 | * used. In all other cases the OS will transparently convert | |
39 | * formats, so no other fallback is needed. | |
40 | * | |
41 | * When copying or cutting (sending data to the OS), the data is | |
42 | * announced and stored internally, but only actually rendered on | |
43 | * request. The requester determines the format provided. The | |
44 | * {next-}selection-coding-system is only used, when its corresponding | |
45 | * clipboard type matches the type requested. | |
46 | * | |
47 | * Scenarios to use the facilities for customizing the selection | |
48 | * coding system are: | |
49 | * | |
50 | * ;; Generally use KOI8-R instead of the russian MS codepage for | |
51 | * ;; the 8-bit clipboard. | |
52 | * (set-selection-coding-system 'koi8-r-dos) | |
53 | * | |
54 | * Or | |
55 | * | |
56 | * ;; Create a special clipboard copy function that uses codepage | |
57 | * ;; 1253 (Greek) to copy Greek text to a specific non-Unicode | |
58 | * ;; application. | |
59 | * (defun greek-copy (beg end) | |
60 | * (interactive "r") | |
61 | * (set-next-selection-coding-system 'cp1253-dos) | |
62 | * (copy-region-as-kill beg end)) | |
63 | * (global-set-key "\C-c\C-c" 'greek-copy) | |
64 | */ | |
65 | ||
66 | /* | |
67 | * Ideas for further directions: | |
68 | * | |
69 | * The encoding and decoding routines could be moved to Lisp code | |
70 | * similar to how xselect.c does it (using well-known routine names | |
71 | * for the delayed rendering). If the definition of which clipboard | |
72 | * types should be supported is also moved to Lisp, functionality | |
73 | * could be expanded to CF_HTML, CF_RTF and maybe other types. | |
