This program lets you make visual music sheets for Sky: Children of the Light. It will ask you a few questions, and does not require previous knowledge of the command line to run.
The program requires Python >= 3.6 and the following packages:
- PIL (preferably pillow)
- import_resources (for Python < 3.8)
- mido (optional: for generating midi output)
- requests (optional: for generating a link to skymusic.herokuapp.com)
The program can be installed by simply unzipping the code on your computer, and running the main script file, or by installing it in your Python distribution with pip:
pip install .
The program can be installed on a desktop computer, or a smartphone if a Python IDE is installed (such as Pythonista).
The program can also be installed in a virtualenv to mitigate possible dependency clashes with system site-packages.
git clone https://github.com/sky-music/sky-python-music-sheet-maker.git cd sky-python-music-sheet-maker python3 -m venv --clear venv source venv/bin/activate pip3 install -r requirements.txt
You can activate the virtual environment with
source venv/bin/activate, to exit the virtual enviroment use the
deactivate command. Note, it is possible some packages are distributed via
bdist_wheel, hence the wheel package may be required.
See here for further details on how to download and install.
If you’re afraid of the command line, there is a website running this script.
There is also a bot running an older version of the program, on thatskygame Discord server, that can be called by typing
!song in a channel.
Executable binaries are also available for download at https://sky-music.github.io.
Running the script
If you have installed the program by pip, just type:
As well as using QWERT ASDFG ZXCVB keys on the keyboard (like a piano), there are other supported notations for the notes you provide:
- Sky column/row notation (A1 A2 A3 A4 A5, B1 B2 B3 B4 B5, C1 C2 C3 C4 C5)
- English notation, followed by an optional number for octaves (C1, D1, E1, F1, G1, A1, B1)
- Jianpu (1 2 3 4 5 6 7, followed by + or - for octaves)
- French do ré mi + octave number
- Japanese do ré mi + octave number
Note that for musical notations supporting octaves (such as English, Jianpu, and doremi), the starting octave is 1, by convention. Typing a note name without octave (e.g. F) implicitely assumes that it belongs to the starting octave (e.g. F1). However for notes belonging to the next octave (higher pitch), you will have to use the number 2 (C2, D2, E2, etc). So the full range of the piano write C1-C3.
This convention is different from SkyStudio's which assumes that the instrument range is C4-C6 (this is true for the basic Sky piano, but not for other instruments such as the winter piano). If you're used to start the octave at 4 (C4, D4, E4...), then enter -3 when asked for an octave shift.
You can type these directly in the command line prompt, but you are strongly advised to save the notes first in a text file. Text files are looked for by the program in the 'test_songs' folder. if you installed the program with pip, this folder must be moved in the Documents folder of your user home directory.
The output will be HTML, SVG, or PNG, with small icons of the Sky keyboard. If you use Western notation or Jianpu notation, it will also convert to Sky notation (ABC1-5) in a text file.
After generating a sheet, you are encouraged to publish the file on https://sky-music.github.io
In contrast with the website or bot versions, the command-line version supports functions for faster processing of songs:
the default answer to any question can be put in the skymusic_preferences.yaml file. This way, you will no longer be asked this question (for instance the aspect ratio of the visual sheet). You can even put the notes in there!
songs can be processed in a batch by placing preference-like .yaml files in the batch_songs directory (see the example files in this folder to learn the right keywords) and passing the following flag to command_line_player.py:
HTML visual sheets generated after July, 2020 1st can be read again by the program for further modification. These sheets can be recognized by the <div class="ascii"> field they contain.
Customized configurations for default directory are supported via command line flags, flags that are not passed or are not valid will reference their default fallback values defined in command_line_player.py:
input/output directories where the module will read from/write to can be defined by passing the following flag with the desired directory to command_line_player.py respectively:
--in_dir <path/to/input/dir/> --out_dir <path/to/output/dir>
a custom batch directory for storing preference .yaml files can be defined by passing the following flag with the desired directory to command_line_player.py:
the default preference .yaml file path where command_line_player.py reads from can be modified by passing the follow flag with the desired path:
by default, conversion of the song to a music recording using JSON format is disabled. A link to hear the song being played on https://sky-music.herokuapp.com can be generated, to enable it setting the following flag with the website API key (this key will be given to trusted players):
Note that to minimize strain to the <sky-music.herokuapp.com> server, the
-b/--batch_mode flags are mutually exclusive, meaning that only either one of them can be passed to the module but not both. Further help can be invoked via the
Note: json recording feature requires the
requests library, which can be installed via the
pip package manager by running:
pip install requests
Since it might be a bit difficult to ensure that all client python3 installations are functional and reproducible, there is a Dockerfile and Compose file provided. The Dockerfile contains the instructions to assemble a base image to run skymusic, while the Compose file orchestrate the instructions to run the image.
The prebuilt containers have the base skymusic modules included.
INPUT_DIR specifies where the container will look for song inputs.
OUTPUT_DIR is where the container will output generated music sheets.
INPUT_DIR=/path/to/dir/containing/test/songs \ OUTPUT_DIR=/path/to/output/dir/ \ docker-compose run skymusic
After running, the output will be placed in
/tmp/output/, referring to the path inside the container. Your
OUTPUT_DIR is bind mounted to
The first time you execute the above command, Docker will pull the image from the Docker Registry and cache it. Any subsequent runs will utilize the cached image.
Note this is a development image with all optional dependencies included.
