Messages sent between the client and server are a series of concatenated strings delimited by the vertical tab character, represented in most languages by the escape sequence `\t` and defined in ASCII as `0x09`. +The first string in this concatenation must be the packet identifier, sent as an `int`. + +Newer versions of the protocol are implemented as extensions, a client for Version 1 should have no trouble using a server built for Version 2 as long as authentication is understood. + +The current stable version of the protocol is **Version 1**. + + +## Types + +### `bool` +A value that indicates a true or a false state. `0` represents false and anything non-`0` represents true, please stick to `1` for representing true though. + + +### `int` +Any number ranging from `-9007199254740991` to `9007199254740991`, `Number.MAX_SAFE_INTEGER` and `Number.MIN_SAFE_INTEGER` in JavaScript. + + +### `string` +Any printable unicode character, except `\t` which is used to separate packets. + + +### `timestamp` +Extends `int`, contains a second based UNIX timestamp. + + +### `channel name` +A `string` containing only alphanumeric characters (any case), `-` or `_`. + + +### `session id` +A `string` containing only alphanumeric characters (any case), `-` or `_`. + + +### `color` +Any valid value for the CSS `color` property. +Further documentation can be found [on MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value). + + +### `message flags` +Message flags alter how a message should be displayed to the client, these are all `bool` values. +The parts are as follows: + + - Username should appear using a **bold** font. + - Username should appear using a *cursive* font. + - Username should appear __underlined__. + - A colon `:` should be displayed between the username and the message. + - The message was sent privately, directly to the current user. + +As an example, the most common message flagset is `10010`. This indicates a bold username with a colon separator. + + +### `user permissions` +User permissions are a set of flags separated by either the form feed character (`\f` / `0x0C`) or a space ( / `0x20`). +The reason there are two options is due to a past mixup that we now have to live with. +Which of the methods is used remains consistent per server however, so the result of a test can be cached. + + + + + + + + + + + + + + + + + + + + + + + + + + + +
intRank of the user. Used to determine what channels a user can access or what other users the user can moderate.
boolIndicates whether the user the ability kick/ban/unban others.
boolIndicates whether the user can access the logs. This should always be 0, unless the client has a dedicated log view that can be accessed without connecting to the chat server.
boolIndicates whether the user can set an alternate display name.
intIndicates whether the user can create channel. If 0 the user cannot create channels, if 1 the user can create channels but they are to disappear when all users have left it and if 2 the user can create channels that permanently stay in the channel assortment.
