  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.

 317 //  1. xxx.keys files under /usr/share/mime-info
 318 //  2. xxx.keys files under ~/.gnome/mime-info
 319 //
 320 // The format of xxx.keys file is the following:
 321 //
 322 // mimetype/subtype:
 323 //      field=value
 324 //
 325 // with blank lines separating the entries and indented lines starting with
 326 // TABs. We're interested in the field icon-filename whose value is the path
 327 // containing the icon.

 329 // Update (Chris Elliott): apparently there may be an optional "[lang]" prefix
 330 // just before the field name.
