Question 1

How do I integrate Reggae with an existing D project using dub?

Accepted Answer

Run `reggae` in the build directory of a Dub project to generate targets for building and testing. For advanced use, write a `reggaefile.d` that uses Dub build information, such as creating concurrent builds for production and unittest binaries with the dubBuild API.

Question 2

Reggae vs CMake: which is better for C++ projects?

Accepted Answer

Reggae offers more flexibility by allowing build logic in general-purpose languages and multiple backends, but CMake has a larger ecosystem and better IDE integration. Choose Reggae if you prefer programming language expressiveness, but CMake for broader toolchain support.

Question 3

Can Reggae detect changes in Python build scripts automatically?

Accepted Answer

Reggae can detect changes to the main build file like `reggaefile.py`, but currently cannot detect changes in imported Python modules, which is a limitation for complex scripting builds, as mentioned in the README.

Question 4

How to switch from Ninja to Make backend in Reggae?

Accepted Answer

Simply run `reggae` with the `-b` option followed by the desired backend, e.g., `reggae -b make /path/to/project`. This regenerates the build system without altering the build description, allowing easy experimentation.

Question 5

What are the drawbacks of using the tup backend with Reggae?

Accepted Answer

The tup backend has reduced functionality: it doesn't support Dub integration and other features due to tup's nature, making it suitable only for simpler builds, as advised in the README where 'simple is better' for tup.

Question 6

How to create a standalone build with Reggae that doesn't require installation?

Accepted Answer

Use the `--export` option when running Reggae to generate a build system in the project root that works independently. This is useful for distributing software without requiring Reggae on the target machine, similar to autotools.

Question 7

Does Reggae support incremental builds for C++ projects?

Accepted Answer

Yes, Reggae supports incremental builds through backends like Ninja and Make, which inherently handle incremental compilation. Automatic dependency detection ensures only changed files are recompiled, improving build efficiency.
