Question 1

How to add dependencies in DUB?

Accepted Answer

Add the dependency name and version to the 'dependencies' section in your dub.json file. For example, specify 'vibe-d': '~>0.8.0' to use vibe.d. DUB will automatically download it from the registry when you run dub build.

Question 2

DUB vs using DMD directly for building D projects?

Accepted Answer

DUB simplifies dependency management and automatic builds, handling downloads and compilation in one step, while DMD alone requires manual dependency handling and script writing. DUB is better for projects with multiple dependencies, but DMD offers more control for simple, script-based builds.

Question 3

Can DUB handle projects with C or C++ code?

Accepted Answer

DUB is primarily designed for D code, but it can handle mixed-language projects through build settings in dub.json. For complex C/C++ integration, you might need external tools or custom build steps, as DUB's support is limited.

Question 4

How to publish a package to code.dlang.org?

Accepted Answer

Ensure your project has a dub.json file and is in a Git repository, then use the dub publish command. This registers your package on the central registry, making it available for others to use and share.

Question 5

Does DUB support cross-compilation?

Accepted Answer

Yes, DUB supports cross-compilation by allowing you to specify compiler flags and target architectures in dub.json. However, setup may require manual configuration depending on the compiler and target platform, such as using --arch flags with DMD.

Question 6

What if the central registry is down?

Accepted Answer

DUB caches downloaded packages locally, so builds can proceed offline once dependencies are fetched. However, adding new dependencies or updating existing ones will fail without registry access, which can disrupt development.
