groan

The command dispatching framework beneath everything else — hierarchical CLIs composed from bash.

groan is a basis for building complex hierarchical command interfaces with bash and other languages, and it aspires to achieve this with some degree of elegance, through hierarchical composition.

The whole estate is built on it. angel is a groan suite, bashaform is a groan suite, and so are the tools that sit inside them. A command is found by its path rather than by a table of aliases, so the shape of the command line follows the shape of the thing being operated.

The rule that makes it work: a sub-tool owns its own commands and knows nothing about its siblings. Composition happens by inclusion, so a suite is a tree rather than a program.
