This program (ga) create the files which Autolab's autograde needed for NTU BME Computer Programming Course. File tree is as follow,

├───autograde-Makefile
├───autograde.tar
│   ├───score.py
│   └───gtest.cpp
├───answers.yml

You can walk through autograde-Makefile to have the overview of whole concept.

score.py is the main code to grade student score.

gtest.cpp is the Google Test code.

• curl: get source code template.
• jq (v1.5): command-line JSON processor.
• yq (v3.4.0): command-line YAML processor.
• gtest: google unit test
• g++

git clone https://github.com/WesleyCh3n/NTUBME-Autograde.git & cd NTUBME-Autograde
sudo make install

ga [-n <HW number>] [-L] -Y <answer.yml>

-n: create blank answer.yml with HW number

-Y: parsing YAML file

-L: for scoring lab purpose

In detail:

1. First, goto the homework folder, ex. ~/Autolab/courses/<course_name>/<hw_name>/.

2. Create sample answers.yml by typing

   ga
   

3. In answers.yml, modify parameters to create the tests you want:

   ---
   Autograde:
     Homework: 4c
     AdditionalTar: ["./Document.txt", "./foo.txt"]
     VariableType: [int, float, double]
     Test:
       - input: [1, 0.2, -32]
         answer:
           - L: abs(ans1)
             op: '<='
             R: 11/3

4. Once you finished editing, type following cmd to generate autograding code

   ga -Y answers.yml
   

Google Test field (Test:): using yaml list syntax to store the lists of tests also lists of logical operation each test. Remember not to write unnecessary -, that may loss some of tests.

This is an example of two test with one and two logical operations.

...
  Test:
    - input: []
      answer:
        - L:
          op: ''
          R:
    - input: []
      answer:
        - L:
          op: ''
          R:
        - L:
          op: ''
          R:

If there is no input, leave it empty. If there is no test, just delete Test: field.

• Put following code to shellrc(e.g. ~/.bashrc) to use ga normally as cli.

ga() {
    docker run --rm -e HOST_USER_ID=$(id -u) -e HOST_USER_GID=$(id -g) -v `pwd`:/workdir/ ghcr.io/wesleych3n/autograde:latest ga $@
}
  
# After re-login
# ga -n {HW number}
# ga -Y {filename}.yml
