Unreleased

0.4.0 (2026-10-12)

• Fix weak refs losing their weak status in expand-inline-defs. The walk that tagged inline defs rebuilt every collection without its metadata, so remove-dead-refs found no weak refs and unselected components were started anyway.
• remove-dead-refs now rebuilds :donut.system/graphs. It used to return the graphs it was given, which could still include the components that removed refs pointed to.
• Remove the dependency on com.rpl/specter. Add it to your own deps if you were relying on sys-ext to bring it in.
• Upgrade party.donut/system to 1.0.259.

0.3.1 (2025-11-20)

• Fix references to transform-weak-refs in docstrings, a early draft function that was never committed. These have been changed to refer to remove-dead-refs. See https://github.com/john-shaffer/sys-ext/issues/1.

v0.3.0 (2025-06-20)

• Update docstrings for call and first-cycle.
• Add select-targets function for selecting component names from a set of groups.
• Allow weak refs that allow a component to wait for another component without creating a hard dependency.

v0.2.0 (2025-06-13)

• Add a first-cycle function to find a cycle in the system. Systems are not supposed to contain cycles, but when they do it is useful to detect it and produce an informative message.
• Add sys-ext.graph/cycle-error function to produce an [[ExceptionInfo]] from a cycle path.

v0.1.0 (2024-04-17)

• Add call component that calls a function when started.
• Add merge component that merges maps when started.
• Add expand-inline-defs function. This expands component defs that are found inside another component's config. This is convenient for small data adjustments like type conversions and lookups.
