6903229c | 90 | COMMAND is a list that specifies the operation, an I/O primitive, as its |
9e361827 EZ |
91 | CAR, and the arguments that might be given to that operation as its CDR. |
92 | If operation is `insert-file-contents', the coding system is chosen based | |
93 | upon the filename (the CAR of the arguments beyond the operation), the contents | |
94 | of `untranslated-filesystem-list' and `file-name-buffer-file-type-alist', | |
95 | and whether the file exists: | |
f473b0ca GV |
96 | |
97 | If it matches in `untranslated-filesystem-list': | |
5cbb3e93 EZ |
98 | If the file exists: `undecided' |
99 | If the file does not exist: `undecided-unix' | |
f473b0ca GV |
100 | If it matches in `file-name-buffer-file-type-alist': |
101 | If the match is t (for binary): `no-conversion' | |
102 | If the match is nil (for dos-text): `undecided-dos' | |
ee425fc3 | 103 | Otherwise: |
f473b0ca | 104 | If the file exists: `undecided' |
b56a5ae0 | 105 | If the file does not exist default value of `buffer-file-coding-system' |
ee425fc3 | 106 | |
6903229c EZ |
107 | Note that the CAR of arguments to `insert-file-contents' operation could |
108 | be a cons cell of the form \(FILENAME . BUFFER\), where BUFFER is a buffer | |
109 | into which the file's contents were already read, but not yet decoded. | |
110 | ||
9e361827 | 111 | If operation is `write-region', the coding system is chosen based upon |
99bf72f2 GV |
112 | the value of `buffer-file-coding-system' and `buffer-file-type'. If |
113 | `buffer-file-coding-system' is non-nil, its value is used. If it is | |
114 | nil and `buffer-file-type' is t, the coding system is `no-conversion'. | |
115 | Otherwise, it is `undecided-dos'. | |
116 | ||
117 | The two most common situations are when DOS and Unix files are read | |
118 | and written, and their names do not match in | |
119 | `untranslated-filesystem-list' and `file-name-buffer-file-type-alist'. | |
120 | In these cases, the coding system initially will be `undecided'. As | |
121 | the file is read in the DOS case, the coding system will be changed to | |
122 | `undecided-dos' as CR/LFs are detected. As the file is read in the | |
123 | Unix case, the coding system will be changed to `undecided-unix' as | |
124 | LFs are detected. In both cases, `buffer-file-coding-system' will be | |
125 | set to the appropriate coding system, and the value of | |
126 | `buffer-file-coding-system' will be used when writing the file." | |
