← Console commands

Switches contexts or prints the current context.

context client

Arguments

• name (optional) - The name of the context to switch to. If no name, then prints the name of the current context.

Details

The 'context' command allows changing between named contexts. Each context may have its own commands and variables and rules, and purpose.

For a context to be available, it has to be associated with the one you are in. These associations are created by the various engine modules and can never be directly added or removed by console commands, or any type of script or AddOn.

Although doesn't involve the 'context' command, context names can also be used to reference facilities in other contexts directly, rather than by switching first.

Examples

Default values

• Try to change to a non-existent context.

> context bob
Unknown: bob

• Called with no name. The current context is printed.

> context
global

Context seperation

• Same as the first example. But change to the known 'client' context, which is addressable from the 'global' context.

> context client

• Start the client service, and change the client 'bob' variable which exists only in the 'client' context.

> start
Client started.
> bob 8081
> bob
'bob' is '8081'
> context
client

• Change back to the 'global' context. Test to see that the bob variable in 'client' is not in 'global'.

> context global
> context
global
> bob
Unknown: bob

Without switching

In these examples a context is addressed directly without using the context command.

• Show current context.

> context
global

• Start the client service directly from global without switching.

> client start
Client started.

• Set the 'bob' variable in client, check its value in 'client', and verify it's not in 'global'.

> client bob 8081
> client bob
'bob' is '8081'
> bob
Unknown: bob
