| 81 * The information below is used for communication between processes | |
| 82 * during "send" commands. Each process keeps a private window, never | |
| 83 * even mapped, with one property, "Comm". When a command is sent to | |
| 84 * an interpreter, the command is appended to the comm property of the | |
| 85 * communication window associated with the interp's process. Similarly, | |
| 86 * when a result is returned from a sent command, it is also appended | |
| 87 * to the comm property. | |
| 88 * | |
| 89 * Each command and each result takes the form of ASCII text. For a | |
| 90 * command, the text consists of a nul character followed by several | |
| 39 | 91 * nul-terminated ASCII strings. The first string consists of a |
| 92 * single letter: | |
| 93 * "c" for an expression | |
| 94 * "k" for keystrokes | |
| 95 * "r" for reply | |
| 96 * "n" for notification. | |
| 97 * Subsequent strings have the form "option value" where the following options | |
| 98 * are supported: | |
| 7 | 99 * |
| 100 * -r commWindow serial | |
| 101 * | |
| 102 * This option means that a response should be sent to the window | |
| 103 * whose X identifier is "commWindow" (in hex), and the response should | |
| 104 * be identified with the serial number given by "serial" (in decimal). | |
| 105 * If this option isn't specified then the send is asynchronous and | |
| 106 * no response is sent. | |
| 107 * | |
| 108 * -n name | |
| 109 * "Name" gives the name of the application for which the command is | |
| 110 * intended. This option must be present. | |
| 111 * | |
| 39 | 112 * -E encoding |
| 113 * Encoding name used for the text. This is the 'encoding' of the | |
| 114 * sender. The receiver may want to do conversion to his 'encoding'. | |
| 115 * | |
| 7 | 116 * -s script |
| 117 * "Script" is the script to be executed. This option must be | |
| 118 * present. Taken as a series of keystrokes in a "k" command where | |
| 119 * <Key>'s are expanded | |
| 120 * | |
| 121 * The options may appear in any order. The -n and -s options must be | |
| 122 * present, but -r may be omitted for asynchronous RPCs. For compatibility | |
| 123 * with future releases that may add new features, there may be additional | |
| 124 * options present; as long as they start with a "-" character, they will | |
| 125 * be ignored. | |
| 126 * | |
| 127 * A result also consists of a zero character followed by several null- | |
| 128 * terminated ASCII strings. The first string consists of the single | |
| 129 * letter "r". Subsequent strings have the form "option value" where | |
| 130 * the following options are supported: | |
| 131 * | |
| 132 * -s serial | |
| 133 * Identifies the command for which this is the result. It is the | |
| 134 * same as the "serial" field from the -s option in the command. This | |
| 135 * option must be present. | |
| 136 * | |
| 137 * -r result | |
| 138 * "Result" is the result string for the script, which may be either | |
| 139 * a result or an error message. If this field is omitted then it | |
| 140 * defaults to an empty string. | |
| 141 * | |
| 142 * -c code | |
| 143 * 0: for OK. This is the default. | |
| 144 * 1: for error: Result is the last error | |
| 145 * | |
| 146 * -i errorInfo | |
| 147 * -e errorCode | |
| 148 * Not applicable for Vim | |
| 149 * | |
| 150 * Options may appear in any order, and only the -s option must be | |
| 151 * present. As with commands, there may be additional options besides | |
| 152 * these; unknown options are ignored. | |
