New features

• Map.Delete removes values by selector. It takes one or more selectors in the same dot and bracket notation as Get and Set, removes the map keys or slice elements they point to, and returns the map so calls can be chained:

  m.Delete("books[1].chapters[2].title", "draft")

  Selectors run in order, so after a slice element is removed, later selectors see the shifted indexes. Missing paths and out-of-range indexes are ignored. Removing a slice element builds a new slice of the same type ([]string stays []string) and leaves the original backing array untouched. Maps along the path are modified in place. (#174)

What's Changed

• feat: add Delete method to Map by selector by @00200200 in #174

New Contributors

• @00200200 made their first contribution in #174

Full Changelog: v0.7.0...v0.8.0

Upgrade notes

Behavior changes

• Has now reports keys whose value is nil. Map.Has used to return false both for missing keys and for keys set to nil, so the two couldn't be told apart. It now returns true whenever the selector exists, including nested keys, bracket keys and slice indexes that hold nil. If you relied on Has to mean "set and not nil", use !m.Get(selector).IsNil() instead. (#172)

Other

• Added a contributing guide (#183), a security policy (#182) and issue templates (#184).
• The Go workflow token is now restricted to read-only contents (#181).

Upgrade notes

Go 1.25 or later is now required (previously Go 1.20). (#175)

Behavior changes

• Where* now returns the items the decider selects. Previously every Where* method (WhereInt, WhereStr, WhereMSI, WhereObjxMap, …) returned the items for which the decider returned false, the opposite of what its documentation says. If you negated your decider to work around this, remove the negation. (#180)
• Indexed Set updates the element instead of replacing the slice. Set("names[0]", "Mat") used to replace the whole names slice with "Mat"; it now sets only the first element. Indexing into a value that isn't a slice (e.g. Get("name[0]") on a string) now returns a missing value instead of the value itself. (#170)
• Nil slices and maps stay null in JSON. objx.Map{"items": []any(nil)} now encodes as {"items":null} instead of {"items":[]}. Empty, non-nil containers still encode as [] / {}. (#171)
• URLValues keeps every element of a slice of maps. With the [] and "" key suffixes, only the last element's values used to be kept. []any values (e.g. arrays decoded from JSON) are now encoded element by element instead of as a Go-syntax string. (#177)
• The error returned by SetURLValuesSliceKeySuffix for an invalid suffix now reads objx: invalid URLValuesSliceKeySuffix provided. (#176)

Other

• The API now uses any instead of interface{}. They are the same type, so this doesn't affect callers. (#175)
• The type-specific accessors are now generated with go generate (#179), and CI runs golangci-lint (#176, #178).
