A java build tool for novices, that doubles as a scriptable autograder.
Rustdoc can be found at https://umm-docs.pages.dev/umm/
You would need rust installed, ideally the nightly toolchain. You can visit https://rustup.rs/ to find out how to install this on your computer, just make sure you install the "nightly" toolchain instead of stable.
On Linux, Windows Subsystem for Linux (WSL), and Mac you should be able to run curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain nightly on a terminal to install the nightly toolchain for rust.
Once you are done, just type cargo install --git=https://github.com/DhruvDh/umm.git, and it should compile and install it on your system.
Also allows for running auto-grading scripts based on Rhai.
Rhai is a lightweight embeddable scripting language meant to make it easy to use your Rust-written structs, their methods, and your functions dynamically without the need for recompilation.
Here are some structs (classes) to help you get going -
This is an in-progress draft.
method_name(arguement_types) -> return_type
-
JavaProject- Struct representing a Java project.new_java_project() -> JavaProject- initializes a java project by discovering files in the source path directory. Also downloads jar files if needed.identify(String) -> JavaFile- attempts to identify the correct file from the project from a partial or fully formed name as expected by a java compiler. Returns aJavaFileof the identified file in the project.files() -> Array- returns an array ofJavaFilesdiscovered in the projectinfo()- prints a minified JSON representation of all the files in the project
-
JavaFile- a file in the discovered project representing any class, interface, or test.new_java_file() -> JavaFile- a constructor, is not meant to be used inside a script.JavaFiles should be discovered by the project.check()- checks for compiler errors, and reports them on stdout/stderr. Also ensures a corresponding.classfile is present in the target directory after acheck()completes.doc_check() -> String- asks javac for documentation lints using the-Xdoclintflag. Returns compiler output as a String. There is a parser that can help parse this output which is not currently exposed.run()- runs the file, and prints output to stdout/stderr.query(String) -> Array-> accepts a Treesitter query as a string (use backticks for multiline strings), and returns an Array of Object Maps (dictionary). Each element of the array represents one match, and each object map contains captured variable names as the key, and captured values as the value.test(Array) -> String- Can be called on JUnit test files. It takes in an Array of strings representing test method names. These test methods must exist within this test file. Returns output from JUnit as a string.kind() -> JavaFileType- returns the kind of file (Class, Interface, ClassWithMain, Test)file_name() -> String- returns the name of the file.path() -> String- returns the relative path to the file as a string.test_methods() -> Array- Can be called on JUnit test files. It returns an Array of test_method names discovered in the file.
-
JavaParser- a wrapper around a treesitter parser. There should not be a need to use this, most of the time what you want to do is callquery()on aJavaFile.new_java_parser()- a constructor, not meant to be used inside a script. It is ideal if you useJavaFile'squery().code() -> String- returns the source code the parser is working with.set_code(String)- a setter for the source code the parser is working with.query(String) -> Vec<Dict>- Currently this method returns a value that cannot be used inside a rhai script, please useJavaFile'squery(String)instead.
-
Grade- A struct representing a grade.new_grade(float, float) -> Grade- takes the actual grade received, and the maximum grade as floating point numbers, and returns aGrade.from_string(String) -> Grade- takes a string in this format -"80/100"and returns a newGrade.grade() -> float- a getter for the grade recieved.grade(float)- a setter for the grade received.out_of() -> float- a getter for the maximum grade.out_of(float)a setter for the maximum grade.to_string()- returns the grade in this format as a string -"80/100".
This script is a sample. The script uses several graders, each with its specific function, to evaluate the project and assign a grade.
The first grader, new_docs_grader(), is used to evaluate the project's documentation. It takes the project as input, as well as a list of files to be graded, and assigns a grade out of 10 points, with a penalty of 3 points for poor documentation.
The second grader, new_by_unit_test_grader(), is used to evaluate the project's unit tests. It takes the project, a list of test files, and a list of expected tests as input, and assigns a grade out of 20 points.
The third grader, new_unit_test_grader(), is also used to evaluate the project's unit tests. It takes different inputs than the second grader, such as the names of the target test and class, and a list of excluded methods and avoided calls. It also assigns a grade out of 20 points.
The fourth and fifth graders are similar to the first and second graders but are used to evaluate a different set of files and tests.
The sixth grader, new_by_hidden_test_grader(), is used to evaluate the project's performance on hidden tests. It takes the URL of the hidden test files, the name of the test class, and the requirements it is grading and assigns a grade out of 30 points.
