Installation script for Datalad and related components
Project description
GitHub | PyPI | Issues | Changelog
datalad-installer is a script for installing Datalad, git-annex, and related components all in a single invocation. It requires no third-party Python libraries, though it does make heavy use of external packaging commands.
Installation
datalad-installer requires Python 3.6 or higher. Just use pip for Python 3 (You have pip, right?) to install it:
python3 -m pip install datalad-installer
Alternatively, download the latest version directly from <https://raw.githubusercontent.com/datalad/datalad-installer/master/src/datalad_installer.py>.
Usage
datalad-installer [<global options>] <component>[=<version>] [<options>] <component>[=<version>] [<options>] ...
datalad-installer provisions one or more components listed on the command line. Each component is either a software package (i.e., Datalad or git-annex) or an environment in which software packages can be installed. If no components are specified on the command line, the script defaults to installing the datalad component.
Global Options
- -E FILE, --env-write-file FILE
Append any PATH modifications or other shell commands needed to use the new components to the given file. This option can be specified multiple times. If this option is not given, the data is written to a temporary file whose location is logged at the beginning of the program.
- -l LEVEL, --log-level LEVEL
Set the log level to the given value. Possible values are “CRITICAL”, “ERROR”, “WARNING”, “INFO”, “DEBUG” (all case-insensitive) and their Python integer equivalents. [default value: INFO]
- --sudo <ask|error|ok>
What to do when the script needs to run a command with sudo or privilege escalation: ask for confirmation (default), error, or run without confirmation. This is always “ok” on Windows, where the system always asks for confirmation.
- -V, --version
Display the script version and exit
- -h, --help
Display usage information and exit
Components
venv
Creates a Python virtual environment using python -m venv. Subsequent datalad components on the command line will be installed into this virtual environment by default if not overridden by an intervening componnent.
Options
- -e ARGS, --extra-args ARGS
Specify extra command-line arguments to pass to python -m venv
- --path PATH
Create the virtual environment at PATH. If not specified, the environment will be created in a directory in $TMPDIR.
miniconda
Installs the latest version of Miniconda. Subsequent conda-env components on the command line will use this installation, and subsequent datalad and git-annex components will be installed using this conda by default if not overridden by an intervening component.
The Miniconda installation script is downloaded from $ANACONDA_URL/Miniconda3-latest-$OS-x86_64.{sh,exe}, where $ANACONDA_URL is taken from the environment, defaulting to https://repo.anaconda.com/miniconda.
Options
- --batch
Run the Miniconda installation script in batch (noninteractive) mode. This option is always in effect when installing on Windows.
- -e ARGS, --extra-args ARGS
Specify extra command-line arguments to pass to the Miniconda installation script.
- --path PATH
Install Miniconda at PATH. If not specified, it will be installed in a directory in $TMPDIR.
- --spec SPEC
Space-separated specifiers for packages to install in the Conda base environment after provisioning.
conda-env
Creates a Conda environment. If there is no preceding miniconda component on the command line, Conda must already be installed on the system, and this installation will be used to create the environment.
Subsequent datalad and git-annex components will be installed into this environment by default if not overridden by an intervening component.
Options
- -e ARGS, --extra-args ARGS
Specify extra command-line arguments to pass to the conda create command.
- -n NAME, --name NAME
The name for the new environment. If not specified, a random name will be generated.
- --spec SPEC
Space-separated specifiers for packages to install in the new environment.
neurodebian
Installs & configures NeuroDebian.
Options
- -e ARGS, --extra-args ARGS
Specify extra command-line arguments to pass to the nd-configurerepo command.
git-annex
Installs git-annex. The component takes an -m, --method option specifying the installation method to use; the supported methods are:
apt
autobuild
brew
conda (only supported on Linux)
datalad/git-annex:tested
datalad/git-annex
datalad/packages
deb-url
dmg
neurodebian
snapshot
If no method is specified, or if the method is set to “auto”, then the most recent component on the command line that provides a compatible installation method will be used. If there is no such component, the first supported component from the following list will be used:
conda
apt
neurodebian
brew
autobuild
datalad/packages
A specific version to install can be specified for those methods that support it by suffixing “git-annex” with “=” and the version number on the command line.
The git-annex component also accepts all options for the supported installation methods; options not belonging to whichever method ends up used will be ignored.
datalad
Installs Datalad. The component takes an -m, --method option specifying the installation method to use; the supported methods are:
apt
brew
conda
deb-url
pip
If no method is specified, or if the method is set to “auto”, then the most recent component on the command line that provides a compatible installation method will be used. If there is no such component, the first supported component from the following list will be used:
conda
apt
neurodebian
brew
autobuild
datalad/packages
A specific version to install can be specified for those methods that support it by suffixing “datalad” with “=” and the version number on the command line.
The datalad component also accepts all options for the supported installation methods; options not belonging to whichever method ends up used will be ignored.
