openjd-cli 0.4.4

Provides a command-line interface for working with Open Job Description templates.

Open Job Description - CLI

Open Job Description (OpenJD) is a flexible open specification for defining render jobs which are portable between studios and render solutions. This package provides a command-line interface that can be used to validate OpenJD templates, run OpenJD jobs locally, and more.

For more information about Open Job Description and our goals with it, please see the Open Job Description Wiki on GitHub.

Versioning

This package's version follows Semantic Versioning 2.0, but is still considered to be in its initial development, thus backwards incompatible versions are denoted by minor version bumps. To help illustrate how versions will increment during this initial development stage, they are described below:

1. The MAJOR version is currently 0, indicating initial development.
2. The MINOR version is currently incremented when backwards incompatible changes are introduced to the public API.
3. The PATCH version is currently incremented when bug fixes or backwards compatible changes are introduced to the public API.

Commands

Getting Help

The main openjd command and all subcommands support a --help option to display information on how to use the command.

check

Validates, or reports any syntax errors that appear in the schema of a Job Template file.

Arguments

Name	Type	Required	Description	Example
path	path	yes	A path leading to a Job or Environment template file.	/path/to/template.json
--output	string	no	How to display the results of the command. Allowed values are human-readable (default), json, and yaml.	--output json, --output yaml

Example

$ openjd check /path/to/job.template.json

Template at '/path/to/job.template.json' passes validation checks!

Downloading

You can download this package from:

• PyPI
• GitHub releases

Verifying GitHub Releases

You can verify the authenticity of the release artifacts using the gpg command line tool.

1. Download the desired release artifacts from the GitHub releases page. Make sure to download the corresponding PGP signature file (ending with .sig) as well. For example, if you would like to verify your download of the wheel for version 1.2.3, you should have the following files downloaded:

   openjd_cli-1.2.3-py3-none-any.whl
   openjd_cli-1.2.3-py3-none-any.whl.sig
   

2. Install the gpg command line tool. The installation process varies by operating system. Please refer to the GnuPG website for instructions: https://gnupg.org/download/

3. Save the following contents to a file called openjobdescription-pgp.asc:

4. Import the OpenPGP key for Open Job Description by running the following command:

   gpg --import --armor openjobdescription-pgp.asc
   

5. Determine whether to trust the OpenPGP key. Some factors to consider when deciding whether or not to trust the above key are:

   • The internet connection you’ve used to obtain the GPG key from this website is secure
   • The device that you are accessing this website on is secure

   If you have decided to trust the OpenPGP key, then edit the key to trust with gpg like the following example:

   $ gpg --edit-key A2F0F059BCC40987

   Please note that the shown key validity is not necessarily correct
   unless you restart the program.
   
   gpg> quit
   

6. Verify the signature of the Open Job Description release via gpg --verify. The command for verifying the example files from step 1 would be:

   gpg --verify ./openjd_cli-1.2.3-py3-none-any.whl.sig ./openjd_cli-1.2.3-py3-none-any.whl
