| 13 | // known bugs; there may be others!! chris elliott, biol75@york.ac.uk 27 Mar 01 |
| 14 | |
| 15 | // 1) .mailcap and .mimetypes can be either in a netscape or metamail format |
| 16 | // and entries may get confused during writing (I've tried to fix this; please let me know |
| 17 | // any files that fail) |
| 18 | // 2) KDE and Gnome do not yet fully support international read/write |
| 19 | // 3) Gnome key lines like open.latex."LaTeX this file"=latex %f will have odd results |
| 20 | // 4) writing to files comments out the existing data; I hope this avoids losing |
| 21 | // any data which we could not read, and data which we did not store like test= |
| 22 | // 5) results from reading files with multiple entries (especially matches with type/* ) |
| 23 | // may (or may not) work for getXXX commands |
| 24 | // 6) Loading the png icons in Gnome doesn't work for me... |
| 25 | // 7) In Gnome, if keys.mime exists but keys.users does not, there is |
| 26 | // an error message in debug mode, but the file is still written OK |
| 27 | // 8) Deleting entries is only allowed from the user file; sytem wide entries |
| 28 | // will be preserved during unassociate |
| 29 | // 9) KDE does not yet handle multiple actions; Netscape mode n??ever will |

| 236 | // This class uses both mailcap and mime.types to gather information about file |
| 237 | // types. |
| 238 | // |
| 239 | // The information about mailcap file was extracted from metamail(1) sources |
| 240 | // and documentation and subsequently revised when I found the RFC 1524 |
| 241 | // describing it. |
| 242 | // |
| 243 | // Format of mailcap file: spaces are ignored, each line is either a comment |
| 244 | // (starts with '#') or a line of the form <field1>;<field2>;...;<fieldN>. |
| 245 | // A backslash can be used to quote semicolons and newlines (and, in fact, |
| 246 | // anything else including itself). |
| 247 | // |
| 248 | // The first field is always the MIME type in the form of type/subtype (see RFC |
| 249 | // 822) where subtype may be '*' meaning "any". Following metamail, we accept |
| 250 | // "type" which means the same as "type/*", although I'm not sure whether this |
| 251 | // is standard. |
| 252 | // |
| 253 | // The second field is always the command to run. It is subject to |
| 254 | // parameter/filename expansion described below. |
| 255 | // |
| 256 | // All the following fields are optional and may not be present at all. If |
| 257 | // they're present they may appear in any order, although each of them should |
| 258 | // appear only once. The optional fields are the following: |
| 259 | // * notes=xxx is an uninterpreted string which is silently ignored |
| 260 | // * test=xxx is the command to be used to determine whether this mailcap line |
| 261 | // applies to our data or not. The RHS of this field goes through the |
| 262 | // parameter/filename expansion (as the 2nd field) and the resulting string |
| 263 | // is executed. The line applies only if the command succeeds, i.e. returns 0 |
| 264 | // exit code. |
| 265 | // * print=xxx is the command to be used to print (and not view) the data of |
| 266 | // this type (parameter/filename expansion is done here too) |
| 267 | // * edit=xxx is the command to open/edit the data of this type |
| 268 | // * needsterminal means that a new interactive console must be created for |
| 269 | // the viewer |
| 270 | // * copiousoutput means that the viewer doesn't interact with the user but |
| 271 | // produces (possibly) a lof of lines of output on stdout (i.e. "cat" is a |
| 272 | // good example), thus it might be a good idea to use some kind of paging |
| 273 | // mechanism. |
| 274 | // * textualnewlines means not to perform CR/LF translation (not honored) |
| 275 | // * compose and composetyped fields are used to determine the program to be |
| 276 | // called to create a new message pert in the specified format (unused). |
| 277 | // |
| 278 | // Parameter/filename expansion: |
| 279 | // * %s is replaced with the (full) file name |
| 280 | // * %t is replaced with MIME type/subtype of the entry |
| 281 | // * for multipart type only %n is replaced with the nnumber of parts and %F is |
| 282 | // replaced by an array of (content-type, temporary file name) pairs for all |
| 283 | // message parts (TODO) |
| 284 | // * %{parameter} is replaced with the value of parameter taken from |
| 285 | // Content-type header line of the message. |
| 286 | // |
| 287 | // |
| 288 | // There are 2 possible formats for mime.types file, one entry per line (used |
| 289 | // for global mime.types and called Mosaic format) and "expanded" format where |
| 290 | // an entry takes multiple lines (used for users mime.types and called |
| 291 | // Netscape format). |
| 292 | // |
| 293 | // For both formats spaces are ignored and lines starting with a '#' are |
| 294 | // comments. Each record has one of two following forms: |
| 295 | // a) for "brief" format: |
| 296 | // <mime type> <space separated list of extensions> |
| 297 | // b) for "expanded" format: |
| 298 | // type=<mime type> BACKSLASH |
| 299 | // desc="<description>" BACKSLASH |
| 300 | // exts="<comma separated list of extensions>" |
| 301 | // |
| 302 | // (where BACKSLASH is a literal '\\' which we can't put here because cpp |
| 303 | // misinterprets it) |
| 304 | // |
| 305 | // We try to autodetect the format of mime.types: if a non-comment line starts |
| 306 | // with "type=" we assume the second format, otherwise the first one. |
| 307 | |
| 308 | // there may be more than one entry for one and the same mime type, to |
| 309 | // choose the right one we have to run the command specified in the test |
| 310 | // field on our data. |
