← Console commands

Runs a Lua statement in a Lua runtime.

print("fred")

Arguments

• name - (none)
• value - the verbatim text of the Lua statement or statements to be run

Associations

• Is by default placed in the 'lua' context.
• Is the default command for the 'lua' context.
• Does not have its own command name in 'lua'.

Details

Can be used to run commands as though were directly in a Lua console, if the first statement is not engine command, variable or alias in the 'lua' context.

While the 'lua' context has the ability to hold variables and aliases, they cannot be created from script as the 'lua' context has no 'alias', 'set' or 'var' type script commands added to the context.

Examples

Default values

Below, 'exit' is actually a 'lua' context command, which simply switches to the 'global' context. It is not run in a Lua runtime.

context lua
print(1 + 2)
exit

Prints '3'.

Dual inline scripting

Run Lua from script:

lua print(1 + 2)
> 3

Run script from lua:

var bob fred
context lua
script 'bob'
> fred
exit

Together fluidly:

lua print(1 + 2)
> 3
bob
> fred
context lua
print(1 + 2)
> 3
script 'bob'
> fred

Inline scripting

Lua and JS from script:

var bob fred
lua print(1 + 2)
js print(1 + 3)
bob
context lua
print(1 + 4)
script 'bob james;bob'
exit
context js
print(1 + 5);
script('bob alan;bob');
exit
> 3
> 4
> fred
> 5
> james
> 6
> alan

Notes

• While 'lua_edit' is intended make console Lua commands easy to run, can allow scripts and other types of macros to avoid lots of situations where complex logic would otherwise be required, by simply switching to the 'lua' context and then running a series of single line lua chunks.
