Note that CodeExpression nodes lack the executionPure property that CodeChunk nodes have because they should be side-effect free.

Properties

The CodeExpression type has these properties:

Name	Description	Type	Inherited from
`id`	The identifier for this item.	`String`	`Entity`
`executionMode`	Under which circumstances the code should be executed.	`ExecutionMode`	-
`compilationDigest`	A digest of the content, semantics and dependencies of the node.	`CompilationDigest`	`Executable`
`compilationMessages`	Messages generated while compiling the code.	`CompilationMessage`*	`Executable`
`executionDigest`	The `compilationDigest` of the node when it was last executed.	`CompilationDigest`	`Executable`
`executionDependencies`	The upstream dependencies of this node.	`ExecutionDependency`*	`Executable`
`executionDependants`	The downstream dependants of this node.	`ExecutionDependant`*	`Executable`
`executionTags`	Tags in the code which affect its execution.	`ExecutionTag`*	`Executable`
`executionCount`	A count of the number of times that the node has been executed.	`Integer`	`Executable`
`executionRequired`	Whether, and why, the code requires execution or re-execution.	`ExecutionRequired`	`Executable`
`executionStatus`	Status of the most recent, including any current, execution.	`ExecutionStatus`	`Executable`
`executionInstance`	The id of the kernel instance that performed the last execution.	`String`	`Executable`
`executionEnded`	The timestamp when the last execution ended.	`Timestamp`	`Executable`
`executionDuration`	Duration of the last execution.	`Duration`	`Executable`
`executionMessages`	Messages emitted while executing the node.	`ExecutionMessage`*	`Executable`
`code`	The code.	`Cord`	`CodeExecutable`
`programmingLanguage`	The programming language of the code.	`String`	-
`executionBounds`	The environment in which code should be executed.	`ExecutionBounds`	`CodeExecutable`
`executionBounded`	The execution bounds, if any, on the last execution.	`ExecutionBounds`	`CodeExecutable`
`authors`	The authors of the executable code.	`Author`*	`CodeExecutable`
`provenance`	A summary of the provenance of the code.	`ProvenanceCount`*	`CodeExecutable`
`output`	The value of the expression when it was last evaluated.	`Node`	-

Testing

During property-based (a.k.a generative) testing, the properties of the CodeExpression type are generated using the following strategies.

Property	Complexity	Description	Strategy
`code`	Min+	Generate a simple fixed string of code.	`Cord::from("code")`
	Low+	Generate a random string of up to 10 alphanumeric characters (excludes whitespace whichcan be problematic in Markdown).	`r"[a-zA-Z0-9]{1,10}".prop_map(Cord::from)`
	High+	Generate a random string of up to 100 characters (excluding control characters).	`r"[^\p{C}]{1,100}".prop_map(Cord::from)`
	Max	Generate an arbitrary string.	`String::arbitrary().prop_map(Cord::from)`
