<section1 topic='Introduction' anchor='intro'>
|
|
<p>Many Jabber/XMPP instant messaging clients provide special processing and presentation of the string "/me " at the beginning of a message body. This specification describes the recommended handling of this "command".</p>
|
|
</section1>
|
|
<section1 topic='Recommended Handling' anchor='handling'>
|
|
<p>The /me command <note>The string "/me " is usually pronounced "slash-me".</note> is a text string that enables a human user to type an action phrase and have it be presented in a special way within an instant messaging client. The text string is followed by a verb or verb phrase, such as "/me laughs" or "/me is logging off now". This command does not result in the generation of any XMPP protocol. Instead, the command is sent as-is (e.g., <body>/me laughs</body>) and the receiving client performs string-matching on the first four characters of the data included in the &BODY; element to determine if the message begins with the string "/me ". If the client finds a match, the receiving client will show the message in a special format. It is RECOMMENDED for the client to show the user name, nickname, or handle <note>On the difference between user names, nicknames, and handles, see &xep0165; and &xep0172;.</note> of the sender followed by the verb phrase in italicized text, prepended by the "*" character.</p>
|
|
<p>For example, imagine that the Greek god Atlas is in a chatroom with the other gods and types the following text in his IM client:</p>
|
|
<example caption="A Command"><![CDATA[
|
|
/me shrugs in disgust
|
|
]]></example>
|
|
<p>That text will be sent to all the occupants in the chatroom as follows:</p>
|
|
<example caption="XMPP Stanza"><![CDATA[
|
|
<message from='olympians@chat.gods.lit/Atlas'
|
|
to='olympians@chat.gods.lit'
|
|
type='groupchat'>
|
|
<body>/me shrugs in disgust</body>
|
|
</message>
|
|
]]></example>
|
|
<p>Each recipient's client would then show the message with some special formatting, such as:</p>
|
|
<example caption="Presented Message">
|
|
<span style='margin-left: 5%; font-style: italic;'>* Atlas shrugs in disgust</span>
|
|
</example>
|
|
<p>If the receiving client does not find a match on the string "/me " in the first four characters of the message body, it SHOULD NOT present the text in a special way. For example, the following message bodies do not match:</p>
|
|
<example caption="Some Non-Commands"><![CDATA[
|
|
<body>/meshrugs in disgust</body>
|
|
|
|
<body>/me's disgusted</body>
|
|
|
|
<body> /me shrugs in disgust</body>
|
|
|
|
<body>"/me shrugs in disgust"</body>
|
|
|
|
<body>Why did Atlas say "/me shrugs in disgust"?</body>
|
|
]]></example>

<section1 topic='Accessibility Considerations' anchor='access'>
|
|
<p>This specification describes the /me command in terms of visual presentation. A client that presents messages aurally MAY modify its presentation of /me commands and SHOULD at a minimum transform the string "/me " into the user name, nickname, or handle of the sender.</p>
|
|
</section1>
|
|
<section1 topic='Security Considerations' anchor='security'>
|
|
<p>There are no security concerns related to use of the /me command.</p>
