push triggered actions

Motivation

• Current repository set manager works but requires running manually
• Sometimes faster responses could be more desirable

Existing literature

• Github Edu disucssion on Jenkins
• A blog post about Github + Travis-CI
• A video tutorial and a repository on Github Classroom + Travis-CI

Action plan

• See if utilizing webhooks [0] [1] possible
• Push trigger available
• Which service to use? Travis-CI? Azure?
• Is educational pricing option available?

Expense

• GitHub Edu may not come with Travis-CI

Tests

• Count number of commits
• Count bytes of comments
• Run each script
• Send record to a summary table

Webhook deployment

• How to automate configuring webhooks of each repository?
• Utilize organization-wide webhooks?

Travis-CI

• What if a student changes the .travis.yml file?

Semester vs Weekly

• According to the video tutorial, weekly may work better
• If weekly, configuring 300+ links may take some time?

• add comments 1e05f18 dc7609e 6a961c0 21e1c5b
• add make_folders.sh dc7609e

Consider using subtrees?

• may need to git merge -Xsubtree=<folder> … --allow-unrelated-histories
• Github says
  git pull -s subtree remotename branchname
• Also, pushing commits from the top level to the subtree repository seems to create duplicate commits
  git push <subtree repo> git subtree split --prefix= :<subtree repo branch>
• Then it seems more reasonable to work within a subtree, push to subtree remote, and git pull -s subtree ...

Deploy automatically

Motivation

• Currently this repo is like a master repo
• 1903 or 1909 repos are like deployment repos
• Automate the process

Plan

• From the master branch of this repo
• (For now) locally copy selected files from one repo to another
• Manually push to the deployment repo(s)

Windows terminal

• Google search result https://devblogs.microsoft.com/commandline/introducing-windows-terminal/
  
• Source code : https://github.com/Microsoft/Terminal

Microsoft Store

• Search Windows Terminal
• Found Windows Terminal (Preview)
• Windows 10 18362.0 or later

Windows Terminal

• Start as a PowerShell
• Can add a new tab as a PowerShell
• To run as bash, Ubuntu for Windows seems necessary
• WSL enable / disable seems available in the Control Panel

Control Panel

• Choosing WSL restarts Windows
• Leads to https://aka.ms/wslstore

Back to MS Store

• Ubuntu by Canonical Group
• Download & Start → Install

Windows Terminal

• Start bash

Question

• Which is simpler? git-bash? or Windows Terminal?

need to test with Anaconda

• Anaconda 2018.12 seems to have some problem with matplotlib and numpy
• Installing from .yml recipe works; so miniconda would be fine == testing with miniconda alone may not be sufficient
• Try to regenerate a situation when a student tries to start of his/her own
