Awesome

Welcome

This repository contains the source code for the Mammoth app for iOS, iPadOS and MacOS, released under the GNU Affero General Public License.

Feel free to take a look around. We are not yet taking patches as we still have a little bit of tidying up to do. When we do, there will be a contributor license agreement. Also, over the next week or two we'll start having some simple "infrastructure" (think: discord channel, etc.). Stay tuned... Bear with us; it's launch week and weekend!

The Mammoth Team

Getting Started

Requirements:

We use Arkana to obfuscate API keys and secrets in Mammoth, which requires the following versions:

Ruby 3.1+
Node.js 16+
Xcode 13+
Swift 5+

Clone the repo

% git clone https://github.com/TheBLVD/mammoth.git

Navigate to the repo, and copy the sample.env to .env:

% cd mammoth
% cp sample.env .env

Install rbenv if not already installed. See Installing rbenv below for instructions.
Install a compatible version of ruby:

% rbenv install

Install ruby dependencies to get the needed gems:

% bundle install

Regenerate the ArkanaKeys package for managing API keys and secrets. This step can be repeated as whenever you change your .env file's contents:

% bin/arkana

Installing `rbenv`

Install Homebrew if you don't already have it:

% /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install rbenv using Homebrew:

% brew install rbenv ruby-build

Initialize rbenv by installing it in your zsh profile, and reload the profile (this assumes you are using zsh by default — if you aren't, please run rbenv init instead and follow instructions):

% echo "eval \"\$(rbenv init - zsh)\"" >> ~/.zshrc
% exec zsh

Install a compatible version of ruby, and continue the steps above:

% rbenv install

You can verify the right version of Ruby is installed by running ruby --version:

% ruby --version
ruby 3.2.1 (2023-02-08 revision 31819e82c8) [arm64-darwin22]

Install SwiftLint

brew install swiftlint

Troubleshooting

If you run bin/arkana and see the following, it can't find a valid .env file. Make sure you've copied the provided sample correctly and that it is in the root of the repo.
If you see this in Xcode. Then Arkana has failed to generate the local package. Verify you have a valid .env and run bin/arkana from the root of the repo.
If you run bin/arkana and see the following:

/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/universal-darwin22/rbconfig.rb:21: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777
You must use Bundler 2 or greater with this lockfile.

Ruby 3 is required. Check your ruby version ruby --version, and check Installing rbenv above for instructions on installing a new version.

Adding Private Keys

Steps to adding a new key/value to the project using Arkana. Upfront there are two options.

Global: same key/value for staging and production
Environment: one value for staging, and separate value for production. Both will reference the same key in the app
First Step Add your env name to .arkana.yml either under 'global_secrets' or 'environment_secrets'
Second Step Add the key/value pair to your local .env file and key names to sample.env

NOTE: for global keys, they are added to the top of the file just once like this:

#.env
...
ExampleSecretKey=2903847

If you're using 'environment_secrets' you'll need 2 key/value entries with appended 'Staging' & 'Production':

#.env
...
ExampleSecretKeyStaging=03948092348504
ExampleSecretKeyProduction=02398450349

Finally From the root of the project on the command line run bin/arkana. This embeds the env values in the Arkana swift package and the are now available to call in your code like this

///randomProjectFile.swift


/// env that is global
ArkanaKeys.Global().exampleSecretKey

/// env var for staging
ArkanaKeys.Staging().exampleSecretKey

If bin/arkan throws an error, see troublshooting above ☝.
