Installation

Other operating systems than Debian and macOS are not yet supported. Only macOS allows to build an iOS version of the app.

Dependencies

IMPORTANT: If you only like to run the webserver locally (including all playgrounds and the simulator), you only need to install Python 3. The repository delivers up-to-date built libraries in the docs/ directory.

Note: Android and XCode can be skipped, if you only like to compile and run mathe:buddy simulator. pandoc can be skipped if you do not intend to build the manuals.

• Debian based Linux (e.g. Ubuntu)

  sudo apt install python3 snapd pandoc
  sudo snap install flutter --classic
  

• macOS

  First install the brew package manager.

  brew install git python3 flutter pandoc
  

Then run flutter doctor in a terminal window and install all listed dependencies.

• macOS

  Install Xcode from the App Store and start the application to complete the installation. Then run the following commands from a terminal.

  xcode-select --install
  sudo gem install cocoapods
  brew install --cask android-studio
  brew install bundletool
  

  Run the application Android Studio.app, agree to the licenses and complete the setup. In Android Studio Settings, Choose Appearance & Behavior, System Settings, Android SDK and select in tab [SDK Platforms] (e.g.) Android 13. Then select in tab [SDK Tools] Android SDK Command-line Tools (latest). Click on the Accept button to start the installation.

  In a terminal, run flutter doctor --android-licenses and accept each license with y. Then run flutter doctor again to check installation.

  In case that you do not have no Java runtime, run brew install openjdk to install it. Homebrew will output that you have to run echo 'export PATH="/opt/homebrew/opt/openjdk/bin:$PATH"' >> ~/.zshrc. Do it!

  A recent bug (flutter/flutter#118502) may list Java Errors. Run the following (ugly!) fix:

  cd /Applications/Android\ Studio.app/Contents
  cp -r jbr jre
  

Getting mathe:buddy

You now need to clone the following mathe:buddy repositories. Replace YOUR_FAVORITE_DIRECTORY by a local directory on your disk.

TIP: use GitHub Desktop to clone the repositories (refer to the end of this document).

cd YOUR_FAVORITE_DIRECTORY
git clone https://github.com/mathebuddy/mathebuddy.git
git clone https://github.com/mathebuddy/mathebuddy-public-courses.git

Developers of the core team should use a SSH key pair; see https://docs.github.com/en/authentication/connecting-to-github-with-ssh; and also clone the private repository:

cd YOUR_FAVORITE_DIRECTORY
git clone git@github.com:mathebuddy/mathebuddy.git
git clone git@github.com:mathebuddy/mathebuddy-public-courses.git
git clone git@github.com:mathebuddy/mathebuddy-private-courses.git

WARNING: Never(!!) clone to iCloud / GoogleDrive / OneDrive / NextCloud / Sciebo / ...!

Running the website locally

Run the following commands:

cd YOUR_FAVORITE_DIRECTORY/mathebuddy/docs
python3 -m http.server 8314

Open http://localhost:8314/ in your favorite browser. You may choose some other port than 8314.

Alternatively, you may also use script ./web.sh (or the admin tool ./cmd.sh) in the root directory of the repository.

cd YOUR_FAVORITE_DIRECTORY/mathebuddy
./web.sh

We use VSCode for editing source code. Make sure you install ALL recommended extensions: Open the mathebuddy repository in VSCode, then click on Extensions on the left symbol div. Type @recommended in the search field. Then click on Install on each extension that is not yet installed.
