Following metamail, we accept // "type" which means the same as "type/*", although I'm not sure whether this // is standard. // // The second field is always the command to run. It is subject to // parameter/filename expansion described below. // // All the following fields are optional and may not be present at all. If // they're present they may appear in any order, although each of them should // appear only once. The optional fields are the following: // * notes=xxx is an uninterpreted string which is silently ignored // * test=xxx is the command to be used to determine whether this mailcap line // applies to our data or not. The RHS of this field goes through the // parameter/filename expansion (as the 2nd field) and the resulting string // is executed. The line applies only if the command succeeds, i.e. returns 0 // exit code. // * print=xxx is the command to be used to print (and not view) the data of // this type (parameter/filename expansion is done here too) // * edit=xxx is the command to open/edit the data of this type // * needsterminal means that a new interactive console must be created for // the viewer // * copiousoutput means that the viewer doesn't interact with the user but // produces (possibly) a lof of lines of output on stdout (i.e. "cat" is a // good example), thus it might be a good idea to use some kind of paging // mechanism. // * textualnewlines means not to perform CR/LF translation (not honored) // * compose and composetyped fields are used to determine the program to be // called to create a new message pert in the specified format (unused). // // Parameter/filename expansion: // * %s is replaced with the (full) file name // * %t is replaced with MIME type/subtype of the entry // * for multipart type only %n is replaced with the nnumber of parts and %F is // replaced by an array of (content-type, temporary file name) pairs for all // message parts (TODO) // * %{parameter} is replaced with the value of parameter taken from // Content-type header line of the message. // // // There are 2 possible formats for mime.types file, one entry per line (used // for global mime.types and called Mosaic format) and "expanded" format where // an entry takes multiple lines (used for users mime.types and called // Netscape format). // // For both formats spaces are ignored and lines starting with a '#' are // comments. Each record has one of two following forms: // a) for "brief" format: // // b) for "expanded" format: // type= BACKSLASH // desc="" BACKSLASH // exts="" // // (where BACKSLASH is a literal '\\' which we can't put here because cpp // misinterprets it) // // We try to autodetect the format of mime.types: if a non-comment line starts // with "type=" we assume the second format, otherwise the first one. // there may be more than one entry for one and the same mime type, to // choose the right one we have to run the command specified in the test // field on our data. // ---------------------------------------------------------------------------- // wxGNOME // ---------------------------------------------------------------------------- // GNOME stores the info we're interested in in several locations: // 1. xxx.keys files under /usr/share/mime-info // 2. xxx.keys files under ~/.gnome/mime-info // // Update (Chris Elliott): apparently there may be an optional "[lang]" prefix // just before the field name. void wxMimeTypesManagerImpl::LoadGnomeDataFromKeyFile(const wxString& filename, const wxArrayString& dirs) { wxTextFile textfile(filename); #if defined(__WXGTK20__) && wxUSE_UNICODE if ( !textfile.Open(wxConvUTF8) ) #else if ( !textfile.Open() ) #endif return; wxLogTrace(TRACE_MIME, wxT("--- Opened Gnome file %s ---"), filename.c_str()); wxArrayString search_dirs( dirs ); // values for the entry being parsed wxString curMimeType, curIconFile; wxMimeTypeCommands * entry = new wxMimeTypeCommands; wxArrayString strExtensions; wxString strDesc; const wxChar *pc; size_t nLineCount = textfile.GetLineCount(); size_t nLine = 0; while ( nLine < nLineCount ) { pc = textfile[nLine].c_str(); if ( *pc != wxT('#') ) { wxLogTrace(TRACE_MIME, wxT("--- Reading from Gnome file %s '%s' ---"), filename.c_str(), pc); // trim trailing space and tab while ((*pc == wxT(' ')) || (*pc == wxT('\t'))) pc++; wxString sTmp(pc); int equal_pos = sTmp.Find( wxT('=') ); if (equal_pos > 0) { wxString left_of_equal = sTmp.Left( equal_pos ); const wxChar *right_of_equal = pc; right_of_equal += equal_pos+1; if (left_of_equal == wxT("icon_filename")) { // GNOME 2: curIconFile = right_of_equal; wxFileName newFile( curIconFile ); if (newFile.IsRelative() || newFile.FileExists()) { size_t nDirs = search_dirs.GetCount(); for (size_t nDir = 0; nDir < nDirs; nDir++) { newFile.SetPath( search_dirs[nDir] ); newFile.AppendDir( wxT("pixmaps") ); newFile.AppendDir( wxT("document-icons") ); newFile.SetExt( wxT("png") ); if (newFile.FileExists()) { curIconFile = newFile.GetFullPath(); // reorder search_dirs for speedup (fewer // calls to FileExist() required) if (nDir != 0) { wxString tmp = search_dirs[nDir]; search_dirs.RemoveAt( nDir ); search_dirs.Insert( tmp, 0 ); } break; } } } } else if (left_of_equal == wxT("open")) { sTmp = right_of_equal; sTmp.Replace( wxT("%f"), wxT("%s") ); sTmp.Prepend( wxT("open=") ); entry->Add(sTmp); } else if (left_of_equal == wxT("view")) { sTmp = right_of_equal; sTmp.Replace( wxT("%f"), wxT("%s") ); sTmp.Prepend( wxT("view=") ); entry->Add(sTmp); } else if (left_of_equal == wxT("print")) { sTmp = right_of_equal; sTmp.Replace( wxT("%f"), wxT("%s") ); sTmp.Prepend( wxT("print=") ); entry->Add(sTmp); } else if (left_of_equal == wxT("description")) { strDesc = right_of_equal; } else if (left_of_equal == wxT("short_list_application_ids_for_novice_user_level")) { sTmp = right_of_equal; if (sTmp.Contains( wxT(",") )) sTmp = sTmp.BeforeFirst( wxT(',') ); sTmp.Prepend( wxT("open=") ); sTmp.Append( wxT(" %s") ); entry->Add(sTmp); } } // emd of has an equals sign else { // not a comment and not an equals sign if (sTmp.Contains(wxT('/'))) { // this is the start of the new mimetype // overwrite any existing data if (!
