Correction of software coding projects

One or more non-transitory computer-readable storage media storing one or more instructions which, when executed by one or more computing devices, cause:

• receiving a job from a particular priority queue amongst a plurality of priority queues, the job including a deliverable and a plurality of commands, the deliverable being written in a first programming language, the commands being separate from the deliverable and being written in a correction system language that is configured to evaluate deliverables written in the first programming language, each of the commands comprising executable code that is formatted for at least one of testing or grading the deliverable;
• performing a correction procedure on the deliverable, wherein the correction procedure comprises, for each of the plurality of commands:
• transforming a respective command into a structure of keywords, the keywords comprising functions and operators executable by the one or more computer devices, the structure associated with a flow of execution, the structure including a plurality of nodes, the plurality of nodes including a root node and plurality of parent nodes, each parent node of the plurality of parent nodes having at least one child node, each parent node of the plurality of parent nodes including a keyword in the respective command;
• traversing the structure according to the flow of execution, executing one or more keywords at one or more parent nodes of the plurality of parent nodes;
• and
• determining an output of the respective command based on the execution of the one or more keywords at the one or more parent nodes of the plurality of parent nodes;
• and
• using the outputs of the plurality of commands to generate either a first display or a second display depending on whether the particular priority queue from which the job was received is associated with a first priority or a second priority.

A computer-implemented method, performed by one or more computer devices, the method comprising:

• receiving a computer program correction job from a particular priority queue amongst a plurality of priority queues, the computer program correction job including a set of computer program source code statements for evaluation and a plurality of commands, the set of computer program source code statements being written in a first programming language, the commands being separate from the set of computer program source code statements and being written in a correction system language that is configured to evaluate computer program source code statements written in the first programming language, each command comprising executable code that is formatted for at least one of testing or grading the set of computer program source code statements;
• performing a correction procedure on the set of computer program source code statements by, for each of the plurality of commands:
• transforming a respective command into a structure of keywords, the keywords comprising functions and operators executable by the one or more computer devices, the structure associated with a flow of execution of a correct version of a computer program represented in the set of computer program source code statements, the structure including a plurality of nodes, the plurality of nodes including a root node and plurality of parent nodes, each parent node of the plurality of parent nodes having at least one child node, each parent node of the plurality of parent nodes including a keyword in the respective command;
• traversing the structure according to the flow of execution, executing one or more keywords at one or more parent nodes of the plurality of parent nodes;
• and
• determining an output of the respective command based on the execution of the one or more keywords at the one or more parent nodes of the plurality of parent nodes;
• and
• using the outputs of the plurality of commands to generate either a first display or a second display depending on whether the particular priority queue from which the computer program correction job was received is associated with a first priority or a second priority.
