Getting Started

1. Create config file

The main config file is located in $HOME/.invisible-hand/config.toml.
Run hand config create to create a template and use hand config edit to open it with an editor.

2. (Not required) Getting your client_secret.json for accessing GoogleSheets

To run the command: Announce Grade , follow the steps below to setup your environment first

  1. Follow Authorization for pygsheets to get your credential file (client_secret.json)

  2. Locate your secret file and use hand config copy-client-secret YOUR-SECRET-FILE to copy it into the cache.

    This command would automatically rename your secret file to ($HOME/.invisible-hand/client_secret.json)

    Invite student into your organization from their email. This should be Github's issue.

    about 2 of 80 students got this issue from our previous experience.

Patch Project

Patch to student homework repositories.

Workflow

Take homework : hw3(the title of your homework in github classroom) for example:
The repository: tmpl-hw3 would be your template for initializing homeworks.

1. Create another repo with name tmpl-hw3-revise to update your template

2. Inside tmpl-hw3-revise

  1. Create a revision branch 2-revise-for-node-definition (whatever you like)

name of the branch

  1. Create an issuse with the identiacal title 2-revise-for-node-definition )
  2. the content of that issue would become the content of your PR message.

template issue

3. Open GitHub Classroom

Select your assignment (hw3) and disable assignment invitation URL of hw3

disable invitation url

4. Create an PR to your template repo (hw3)

hand patch-project hw3 --only-repo="tmpl-hw3" 2-revise-for-node-definition

5. Accept the PR in your template repository (tmpl-hw3)

After that, enable the assignment invitation URL of hw3 in GitHub Classroom.
Now you have succcessfully updated your template repo.

6. Create PRs to students template repositories ( hw3-<their github id> )

Patch to every repository that uses hw3 as the prefix under your GitHub organization.

hand patch-project hw3 2-revise-for-node-definition

7. Merge the revision branch 2-revise-for-node-definition inside tmpl-hw3

After this step, all documents are updated

8. Reactivate the invitation URL

reactivate invitation url

Announce Grade

Publish feedbacks by creating Issue to student's homework repo.

This sciprt requires you to + Use a GoogleSpreadSheet to record every student's grade inside a strictly named tab. + Strictly structured Github repository.

Explanation

In our scheme, each student would get a git repository for every homework project.

Take homework hw3 with two students Anna and Bella for example.
We expect there would be 2 repos under our GitHub organization, which are hw3-Anna and hw3-Bella.

Annoucing the grade for hw3 actually means to open 1 issue to hw3-anna and hw3-bella respectively.

To make sure the script correctly functions: + students grade should be recorded in the SpreadSheet with a tab called hw3. + You should keep a Markdown file for each student using their student-id as the filename to describe their homework result. + e.g. (if Anna's sutdent-id is 0856039, then 0856039.md should record Anna's overall feedbacks). + Behold: student-id should be unique.

Format and Structure for those files

  • 0856039.md (Anna)
Hi, @Anna

## Information
+ Grade: ${grade}
  + testcase : ${grade_testcase}/100 pts
  + report : ${grade_report}/5 pts

+ Grader: @{grader}
+ Feedback:
    Good Job

## Note
If you got any questions about your grade
please make a comment stating your arguments below and tag the grader in the comment.

This markdown file contains python template strings(${grade}),
These strings are the column names inside your SpreadSheet tab hw3.

  • Structure of the GitHub Repo:
  . Hw-manager # root of your git repo (the name is configured in `$HOME/.invisible-hand/config.toml`)
  ├── hw3
  │   └── reports
  │       ├── 0411276.md
  │       ├── 0856039.md (**Anna**)
  └── hw4 # other homework dir
  • Structure of the Google SpreadSheet
student_id grade grade_report grade_testcase grader

Instructions to follow

  1. Edit config files properly.
  2. Create feedbacks for students in your feedback_source_repo
  3. Make sure you commit and push the feedbacks to master branch
  4. Fill out the SpreadSheet
  5. Use this script

  6. For testing, it's recommended to use the --only-id option
