Moodle Development Kit

A collection of tools meant to make developers' lives easier.

Requirements

• Linux or Mac OS
• Python 3.6
• MySQL, MariaDB or PostgreSQL
• Git v1.7.7 or greater

Most of the tools work on Moodle 1.9 onwards, but some CLI scripts required by MDK might not be available in all versions.

Usage

The commands are called using that form:

mdk <command> <arguments>

Get some help on a command using:

mdk <command> --help

Also check the wiki.

Docker support

As at MDK 2.1, partial support for Moodle running in Docker is available. Some commands like phpunit, upgrade, run, cron are run in the container. The behat command can also work but still requires some fiddling around. Other commands such as install will not work.

Set the environment variable MDK_DOCKER_NAME to the name of the running container, or enable the config docker.automaticContainerLookup to let MDK look for a matching running container automatically.

Usage examples:

# One command.
$ MDK_DOCKER_NAME=sm mdk phpunit

# Multiple commands.
$ set -x MDK_DOCKER_NAME sm
$ mdk run dev
$ mdk phpunit

# Enable automatic resolution.
$ mdk config set docker.automaticContainerLookup true

# With automatic resolution.
$ cd /path/to/sm
$ mdk phpunit

Compatible containers

The Docker container must be created using moodlehq/moodle-php-apache, here is an example:

# Replace `sm` with the name of your instance.
set -x INSTANCE_NAME sm

# This computes the paths of the instance.
set -x MDK_INSTANCE_DIR (mdk info -v path $INSTANCE_NAME)
set -x MDK_STORAGE_DIR (mdk config show dirs.storage | python -c 'import sys, pathlib; print(pathlib.Path(sys.stdin.read()).expanduser().resolve(), end="")')

# Create a Docker network called `moodle`.
docker network create moodle 2> /dev/null

# Create and start the docker container, change the port, name and PHP version as needed.
docker run -d \
    --name $INSTANCE_NAME \
    --network moodle \
    -v $MDK_INSTANCE_DIR:/var/www/html \
    -v $MDK_STORAGE_DIR/$INSTANCE_NAME/moodledata:/var/www/moodledata \
    -v $MDK_STORAGE_DIR/$INSTANCE_NAME/extra/behat:/var/www/behatfaildumps \
    -p 8800:80 moodlehq/moodle-php-apache:8.1

You will want to create databases in the same network, and other services like selenium.

Installation

Python package

On Debian-based systems, install the following packages:

sudo apt-get install python-pip libmysqlclient-dev libpq-dev python-dev unixodbc-dev

Use pip:

pip install moodle-sdk --user
mdk init

Notes

This method does not require sudo as it installs MDK for the current user. It is assumed that ~/.local/bin is in your PATH (or equivalent).

If it isn't, this snippet for ~/.profile might be useful:

# Set PATH so it includes user's private local bin if it exists.
if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi

Homebrew

Using Homebrew, please refer to this formula.

For development

Clone the repository:

git clone https://github.com/FMCorz/mdk.git moodle-sdk

On Debian-based systems, you will need to install the following packages:

sudo apt-get install python-pip libmysqlclient-dev libpq-dev python-dev unixodbc-dev

Then from the directory where you cloned the repository:

python setup.py develop --user
mdk init

Bash completion

To activate bash completion:

sudo ln -s /path/to/moodle-sdk/extra/bash_completion /etc/bash_completion.d/moodle-sdk

To activate goto commands (gt and gtd), add the following to ~/.bashrc:

if [ -f /path/to/moodle-sdk/extra/goto_instance ]; then
    . /path/to/moodle-sdk/extra/goto_instance
    . /path/to/moodle-sdk/extra/goto_instance.bash_completion
fi

Upgrading

If you installed MDK using PIP, run the following command:

pip install --user --upgrade moodle-sdk

It is possible that a new version of MDK requires new files, directories, etc... and while we try to make it easy to upgrade, it can happen that some features get broken in your environment. So after each upgrade, consider running the following to get more information:

mdk doctor --all

Command list

alias

Set up aliases of your Moodle commands.

Example

This line defines the alias 'upall', for 'moodle update --all'

mdk alias add upall "update --all"

backport

Backport a branch to another instance of Moodle.

Examples

Assuming we are in a Moodle instance, this backports the current branch to the version 2.2 and 2.3

mdk backport --version 22 23

Backports the branch MDL-12345-23 from the instance stable_23 to the instance stable_22, and pushes the new branch to your remote

mdk backport stable_23 --branch MDL-12345-23 --version 22 --push

backup

Backup a whole instance so that it can be restored later.

Examples

Backup the instance named stable_main

mdk backup stable_main

List the backups

mdk backup --list

Restore the second backup of the instance stable_main

mdk backup --restore stable_main_02

behat

Get the instance ready for acceptance testing (Behat), and run the test feature(s).

Examples

mdk behat -r --tags=@core_completion

create

Create a new instance of Moodle. It will be named according to your config file.

Examples

Create a new instance of Moodle 2.1

mdk create --version 21

Create an instance of Moodle 2.2 using PostgreSQL from the integration remote, and run the installation script.

mdk create --version 22 --engine pgsql --integration --install

doctor

Perform some checks on the environment to identify possible problems, and attempt to fix them automatically.

fix

Create a branch from an issue number on the tracker (MDL-12345) and sets it to track the right branch.

Examples

In a Moodle 2.2 instance, this will create (and checkout) a branch named MDL-12345-22 which will track upstream/MOODLE_22_STABLE.

mdk fix MDL-12345
mdk fix 12345

Example

Assuming we type that command on a 2.3 instance, pulls the corresponding patch from the issue MDL-12345 in a testing branch

mdk pull --testing 12345

push

Shortcut to push a branch to your remote.

Examples

Push the current branch to your repository

mdk push

Force a push of the branch MDL-12345-22 from the instance stable_22 to your remote

mdk push --force --branch MDL-12345-22 stable_22

rebase

Fetch the latest branches from the upstream remote and rebase your local branches.

Examples

This will rebase the branches MDL-12345-xx and MDL-56789-xx on the instances stable_22, stable_23 and stable_main. And push them to your remote if successful.

mdk rebase --issues 12345 56789 --version 22 23 main --push

uninstall

Uninstall an instance: removes config file, drops the database, deletes dataroot content, ...

update

Fetch the latest stables branches from the upstream remote and pull the changes into the local stable branch.

Examples

This updates the instances stable_22 and stable_23

mdk update stable_22 stable_23

This updates all your integration instances and runs the upgrade script of Moodle.

mdk update --integration --upgrade

upgrade

Run the upgrade script of your instance.

Examples

The following runs an upgrade on your stable branches

mdk upgrade --stable

This will run an update an each instance before performing the upgrade process

mdk upgrade --all --update

Scripts

You can write custom scripts and execute them on your instances using the command mdk run. MDK looks for the scripts in the scripts directories and identifies their type by reading their extension. For example, a script called 'helloworld.php' will be executed as a command line script from the root of an installation.

# From anywhere on the system
$ mdk run helloworld stable_main

# Is similar to typing the following command
$ cp /path/to/script/helloworld.php /path/to/moodle/instances/stable_main
$ cd /path/to/moodle/instances/stable_main
$ php helloworld.php

Scripts are very handy when it comes to performing more complexed tasks.

Shipped scripts

The following scripts are available with MDK:

• dev: Changes a portion of Moodle settings to enable development mode
• enrol: Enrols users in any existing course
• external_functions: Refreshes the definitions of services and external functions
• makecourse: Creates a test course
• mindev: Minimalist set of development settings (performance friendly)
• setup: Setup for development by running a succession of other scripts
• tokens: Lists the webservice tokens
• undev: Reverts the changes made by dev and mindev
• users: Creates a set of users
• version: Fixes downgrade version conflicts
• webservices: Does all the set up of webservices for you
