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. | |
