Type
Gremlin expression of type a.
Greskell is essentially just a piece of Gremlin script with a
phantom type. The type a represents the type of data that the
script is supposed to evaluate to.
Eq and Ord instances compare Gremlin scripts, NOT the values
they evaluate to.

Literals
Functions to create literals in Gremlin script. Use fromInteger,
valueInt or gvalueInt to create integer literals. Use
fromRational or number to create floating-point data literals.
string :: Text -> Greskell Text Source #
Create a String literal in Gremlin script. The content is automatically escaped.
single :: Greskell a -> Greskell [a] Source #
Make a list with a single object. Useful to prevent the Gremlin Server from automatically iterating the result object.
number :: Scientific -> Greskell Scientific Source #
Arbitrary precision number literal, like "123e8".
gvalueInt :: Integral a => a -> Greskell GValue Source #
Integer literal as GValue type.
Since: 0.1.2.0
Unsafe constructors
Unsafely create a Greskell of arbitrary type. The given Gremlin
script is printed as-is.
Same as unsafeGreskell, but it takes lazy Text.
Unsafely create a Greskell that calls the given function with
the given arguments.
Arguments
| :: Greskell a | target object |
| -> Text | method name |
| -> [Text] | arguments |
| -> Greskell b | return value of the method call |
Unsafely create a Greskell that calls the given object method
call with the given target and arguments.
