12 // known bugs; there may be others!! chris elliott, biol75@york.ac.uk 27 Mar 01
14 // 1) .mailcap and .mimetypes can be either in a netscape or metamail format
15 // and entries may get confused during writing (I've tried to fix this; please let me know
16 // any files that fail)
17 // 2) KDE and Gnome do not yet fully support international read/write
18 // 3) Gnome key lines like open.latex."LaTeX this file"=latex %f will have odd results
19 // 4) writing to files comments out the existing data; I hope this avoids losing
20 // any data which we could not read, and data which we did not store like test=
21 // 5) results from reading files with multiple entries (especially matches with type/* )
22 // may (or may not) work for getXXX commands
23 // 6) Loading the png icons in Gnome doesn't work for me...
24 // 7) In Gnome, if keys.mime exists but keys.users does not, there is
25 // an error message in debug mode, but the file is still written OK
26 // 8) Deleting entries is only allowed from the user file; sytem wide entries
27 // will be preserved during unassociate
28 // 9) KDE does not yet handle multiple actions; Netscape mode never will
31 TODO: this file is a mess, we need to split it and reformet/review

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