Description

Used by the USER_AGENT_PARSER.

Methods

ignored_ids (line 1014)

A list of ids known to be spurious or system ids.

The algorithm always uses the last non-ignored id as the browser id; this list determines which ids are ignored.

public array[string,boolean] ignored_ids ()

os_ids (line 1093)

A mapping of user agent fragments to platform ids.

The platform id is a nicely formatted, standardized name for the operating system. This array maps the different user agent platform ids onto these standard ones. (e.g. 'nt 4' and 'nt4' both map onto 'Windows NT 4.x').

public array[string,string] os_ids ()

renderer_ids (line 976)

A list of the known rendering technologies.

see USER_AGENT_RENDERER_INFO

Each id maps to the rendering technology to record (retrieved later with the 'is' function), a pretty-printed name for the renderer and a level. The level determines which renderers override others if more than one renderer is specified. That is, almost every user-agent on the planet returns mozilla x.x, but that renderer declaration is overridden by any other one that comes along. IE is the next weakest because many user agents spoof as IE as well. If either or both of these are specified, they are recorded, but if any other renderer is specified, that one is used instead.

public array[string,USER_AGENT_RENDERER_INFO] renderer_ids ()

robot_names (line 1077)

A list of names that are commonly robots.

Since there are so many different robot clients, we look for common names in the renderer/browser name to mark unknown browsers as robots.

public array[string,boolean] robot_names ()

system_ids (line 1056)

A list of systems known to provide version info in the user agent.
