depsync v1.4.0

Introduction

A command line tool for automatically synchronizing the dependencies of a project by the DEPS configuration file.

Advantages

The depsync tool provides a convenient way to download git repositories and files from the Internet, offering several key advantages over similar capabilities like git-submodules and git-lfs:

• Repositories are always checked out with a depth of 1 without any extra command arguments, ensuring that the main project maintains a relatively compact size at all times.
• Automatically download git-submodules and git-lfs files for your main project and third-party repositories without the need to run commands on each one individually.
• During downloading process, git-lfs files that already exist in the local cache can be skipped. This approach works even for the shallow cloned repositories.
• Enable the execution of custom actions after synchronization. For instance, you can include commands in the DEPS file to facilitate cleaning tasks and other operations.
• Repositories and files can be configured separately for each platform to avoid downloading unnecessary dependencies and only acquire platform-specific ones.

With all the advantages described above, all it takes is one straightforward command depsync. Execute it in the root of your main project, and you're good to go!

Installation

npm install depsync -g

Usage

Run the following command in the directory with a DEPS file:

depsync [platform]

For example, if you want to synchronize the mac platform, run:

depsync mac

If you don't pass any platform parameter, it will automatically choose the host platform as the target platform. So the result of running depsync in macOS is the same to running depsync mac.

The available platform names are defined in the DEPS file, you can also define any other platform names as you want, such as ios, android... but only the mac, win and linux can be automatically chosen.

Here is an example of DEPS file:
