b

b is a build system.

TODO

• Default rules. If a file doesn't have an associated rule, should it behave like Make where the presence of a file indicates the file is built?

• Concurrency. Need a good, flexible model. MVars or STM for management? Explicit dictionaries for polymorphism?

• More examples. More tests.

• Lazy rechecking, like Make and Shake.

• Server.

Ideas

Core features.

• Remove files built previously from now-deleted file. This will lead to reproduceable build outputs.

• Express commands run as dependencies.

Adoption

• Support Shake DSL.
• Support Ninja files.
• Support CMake directly.

User-land features

• Output capture.
• Filesystem change tracking.
• Execute only rebuilt tests.
• Check files using digests.
• C++ compilation clumping.
• distcc support.
• ccache support.
