Organizes a "Secret Santa" gift exchange event! Given a list of participant names, addresses, and emails, this project randomizes the gift exchange and sends instructions via email to each participant.
This project requires the following packages:
- C++17 Compiler: Any C++17 compiler will do, such as GCC or Clang. On Ubuntu, install GCC with
sudo apt install g++or Clang withsudo apt install clang. - CMake: On Ubuntu, install CMake with
sudo apt install cmake. - S-nail: On Ubuntu, install S-nail with
sudo apt install s-nail.
Additionally, the yaml-cpp library (https://github.com/jbeder/yaml-cpp) is used for parsing YAML files. However, you do not need to install this library; instead, this library is automatically downloaded, built, and linked with this project when this project is configured.
If you intend to use a Gmail email address to send messages, the easiest way of doing so is to create an App Password on your Google account. See https://support.google.com/accounts/answer/185833 for instructions on how to do so. Google App Passwords are not as secure as other more modern options, so it is recommended to delete your App Password once you are done using this project. Better yet, create a new Gmail email address specifically for your Secret Santa event!
The S-nail package requires some configuration. In your home directory, create a .mailrc configuration file with:
touch ~/.mailrc
chmod 0600 ~/.mailrcOpen this file in any text editor, and paste the following contents:
set v15-compat
set verbose
set sendcharsets=utf-8,iso-8859-1
set reply-in-same-charset
set folder=mail
set sendwait
set tls-verify=strict
set tls-ca-file=/etc/ssl/certs/ca-certificates.crt
set tls-ca-no-defaults
set smtp-use-starttls
set smtp-auth=login
set from="myusername@gmail.com"
set mta=smtps://myusername:mypassword@smtp.gmail.com:465Replace myusername with your email address and mypassword with your email password. If using Gmail, the password is your App Password.
Verify that S-nail is correctly configured by sending a short email message to yourself with:
echo "This is a test message." | s-nail --subject "Test Email" myusername@gmail.comAgain, replace myusername with your email address. This should send a short email from yourself to yourself.
Clone this project's repository and configure it with:
git clone git@github.com:acodcha/secret-santa.git
cd secret-santa
mkdir build
cd build
cmake ..
make --jobs=16This builds the main executables:
build/bin/secret-santa-randomizerbuild/bin/secret-santa-messenger
A sample YAML configuration file is shown here: test/configuration.yaml
The YAML configuration file must follow the following schema:
---
message:
subject: <text>
body: <text>
participants:
- <name>:
email: <text>
address: <text>
instructions: <text>
- <name>:
email: <text>
address: <text>
instructions: <text>
[...]The fields are:
message->subject: Subject of the email message that will be sent to each participant. A default value is used if no message subject is defined in the YAML configuration file.message->body: Body of the email message that will be sent to each participant. A default value is used if no message body is defined in the YAML configuration file. Information regarding the participant's giftee is automatically appended to this body.participants: List of participants. Each participant is defined by a name and lists an email address, civic address, and instructions. Participant names must be unique. Participants' email addresses, civic addresses, and instructions are optional.
The Secret Santa Randomizer reads a YAML configuration file containing a list of participants, randomly generates Secret Santa matchings among the participants, and outputs the matchings to a YAML file.
Print usage information to the console by running the Secret Santa Randomizer executable from the build directory with:
bin/secret-santa-randomizer --helpRun the Secret Santa Randomizer executable from the build directory with:
bin/secret-santa-randomizer --configuration <path> [--matchings <path>] [--seed <integer>]The command-line arguments are:
--configuration <path>: Path to the YAML configuration file to be read. Required.--matchings <path>: Path to the YAML matchings file to be written. Optional. If omitted, no matchings file is written.--seed <integer>: Seed value for pseudo-random number generation. If omitted, the seed value is randomized.
A sample YAML matchings file is shown here: test/matchings.yaml
The YAML matchings file must follow the following schema:
---
gifters_to_giftees:
- <gifter-name>: <giftee-name>
- <gifter-name>: <giftee-name>
[...]The gifters_to_giftees sequence lists the names of the matchings of gifters and giftees.
The Secret Santa Messenger reads a YAML configuration file containing a list of participants and the YAML matchings file generated by the Secret Santa Randomizer and sends email messages to each participant informing them of their assigned giftee and containing instructions for the Secret Santa event.
Print usage information to the console by running the Secret Santa Messenger executable from the build directory with:
bin/secret-santa-messenger --helpRun the Secret Santa Messenger executable from the build directory with:
bin/secret-santa-messenger --configuration <path> --matchings <path>The command-line arguments are:
--configuration <path>: Path to the YAML configuration file to be read. Required.--matchings <path>: Path to the YAML matchings file to be read. Required.
Testing is optional, disabled by default, and requires the following additional package:
- GoogleTest: The GoogleTest library (https://github.com/google/googletest) is used for testing. On Ubuntu, install it with
sudo apt install libgtest-dev. When testing is enabled, if the GoogleTest library is not found on your system, it is automatically downloaded, built, and linked with this project when this project is configured.
You may optionally test this project from the build directory with:
cmake .. -DTEST_SECRET_SANTA=ON
make --jobs=16
make testThis builds and runs the tests.
