How to install writable shared and user specific data files with setuptools?
To install writable shared and user-specific data files using setuptools
, you can use the data_files
option in the setup()
function. Here's an example of how you can include writable shared and user-specific data files in your package:
Package Structure: Make sure your package has a directory structure that includes the necessary data files. For example:
arduinomypackage/
mypackage/
__init__.py
data/
shared/
file1.txt
user_specific/
file2.txt
setup.py
Update
setup.py
: Open yoursetup.py
file and import the necessary packages:pythonfrom setuptools import setup
from setuptools.command.install import install
import os
import shutil
import sys
Define Custom
install
Command: Create a custominstall
command that overrides therun()
method. This allows you to perform additional tasks during the installation process:pythonclass CustomInstallCommand(install):
def run(self):
# Call the base implementation of the install command
install.run(self)
# Get the paths of shared and user-specific data directories
shared_data_dir = os.path.join(sys.prefix, "share", "mypackage")
user_data_dir = os.path.join(os.path.expanduser("~"), ".mypackage")
# Copy shared data files to the shared data directory
shared_data_files = ["data/shared/file1.txt"]
for file in shared_data_files:
dest_path = os.path.join(shared_data_dir, os.path.basename(file))
shutil.copy(file, dest_path)
# Create user-specific data directory if it doesn't exist
os.makedirs(user_data_dir, exist_ok=True)
# Copy user-specific data files to the user-specific data directory
user_data_files = ["data/user_specific/file2.txt"]
for file in user_data_files:
dest_path = os.path.join(user_data_dir, os.path.basename(file))
shutil.copy(file, dest_path)
Update
setup()
Function: Modify thesetup()
function to include the custominstall
command and specify thedata_files
option:pythonsetup(
# Other setup options...
cmdclass={"install": CustomInstallCommand},
data_files=[
("share/mypackage", ["data/shared/file1.txt"]),
(os.path.expanduser("~/.mypackage"), ["data/user_specific/file2.txt"])
]
)
In this example, the custom install
command is defined to copy the shared and user-specific data files during the installation process. The data_files
option in the setup()
function specifies the paths of the shared and user-specific data files relative to the package root.
During the installation, the shared data files are copied to the shared data directory (sys.prefix/share/mypackage
), and the user-specific data files are copied to the user-specific data directory (~/.mypackage
).
Make sure to adjust the paths and file names according to your package structure and data files.
By following these steps, you can install writable shared and user-specific data files along with your package using setuptools
.
