Lua scripting

Coralillo uses a few lua scripts to atomically run certain operations. These can be accessed through the engine’s lua object. Here are the available scripts:

engine.lua.drop(args=[pattern])

Deletes all keys matching pattern from the database. Specially useful in tests.

engine.lua.allow(args=[objspec], keys=[allow_key])

Adds objspec to the permission tree stored at allow_key

Script registering

You can add your own scripts using Coralillo’s lua interface like this:

from coralillo import Engine

eng = Engine()

script = 'return ARGV[1]'

eng.lua.register('my_script', script)

assert eng.lua.my_script(args=['hello']) == b'hello'

Lua.register(scriptname, scriptbody)

Registers script defined by scriptbody (a string) so it is accessible through the lua interface of the engine under the name scriptname.
