v0.18.0-alpha.1

Changes which may break some users are marked below with: ⚠️

Language

⚠️ Pattern constraints may no longer be marked as optional or required: [string]?: int and [string]!: int are now rejected by the parser, matching the spec grammar. A pattern constraint is optional by construction, so the markers had no effect; simply remove them (#3716).

The comparison bounds == and != now work with boolean values, so constraints like !=true behave as documented in the spec (#4388).

Fix a spurious parse error for fields named try, such as try: x (#4394).

Evaluator

Several hangs and panics have been fixed: a hang when chaining disjunctions across nested fields (#4453), and panics involving disjunctions (#4447) and pattern constraints with cue eval -e (#4449).

Several bugs causing spurious errors have also been fixed: let bindings referring to their enclosing scope could misresolve or fail as cyclic (#4428, #4440); or() over a cyclic reference could report a spurious structural cycle (#4399); and looking up a field could force the evaluation of unrelated comprehensions and disjunctions, producing errors out of thin air (#4448). Thank you to all who reported these.

"Incomplete value" errors now include the positions of the values involved, making it easier to locate the offending field in a large configuration (#2507).

cmd/cue

⚠️ The new formatter is enabled by default

The formatv2 experiment, announced in v0.17.0, is now enabled by default: cue fmt and the cue/format Go API are backed by a rewritten formatter. The new implementation resolves long-standing issues with the old one, in particular around the alignment of fields and trailing comments and the layout of multi-line expressions, so expect some reformatting when running cue fmt over existing files.

The old formatter remains available via CUE_EXPERIMENT=formatv2=0 for v0.18; v0.17 also accepts the formatv2 experiment name, so the setting can be shared by teams using both versions. Please report any misformatting via the issue tracker, as we intend to remove the old formatter once the new one is stable.

Other changes

CUE packages can now be combined with individual schema and data files in a single invocation, such as cue vet ./schemapkg extra-schema.json data.yaml, and the --package flag now treats individual CUE files the same way as packages (#3341, #3671, #3914).

cue vet now honors all -d/--schema flags rather than only the last one (#3726), and -e expressions now apply only to the selected expressions, avoiding spurious errors from unrelated parts of the input (#3371).

Tool tasks such as exec.Run, file.Read, and cli.Ask now surface evaluation errors in their fields, such as a broken stdin value, rather than silently treating them as unset.

Modules

Imports using a redundant package qualifier, such as foo.com/bar:bar, now resolve correctly in all cases (#4446).

@embed now works in files named directly on the command line within a module, and in packages loaded from dependency modules (#4439).

Wildcard package patterns such as ./.../name now match the package path in full rather than any of its suffixes (#3212), and package directory arguments with a trailing slash or a relative form now behave consistently (#3707).

Module registry errors are clearer: they now name the registry host and the module involved without repeating them at every level (#2952, #3611). cue mod publish now works with registries which reject overwriting existing blobs (#3340).

LSP server

Hovering over a field now shows its value with all conjuncts unified, and doc comments shown on hover now follow the semantic ownership rules of the language, such as attaching to the innermost field of a shorthand like a: b: c (#2672).

The language server is also more robust: it now notices files created on disk which satisfy previously failing imports or @embed patterns, publishes diagnostics for files with syntax errors and clears them for closed files, preserves comments when organizing imports, and fixes several panics and cache staleness bugs.

Encodings

The new yamlgoccy experiment, enabled by default, backs the YAML decoder and encoder with github.com/goccy/go-yaml, which retains more precise position and comment information and resolves a number of parsing bugs, such as the %YAML 1.2 directive being rejected (#3349). The old implementation remains available via CUE_EXPERIMENT=yamlgoccy=0 for v0.18.

The new openapiv2 experiment teaches cue import and cue export to handle complete OpenAPI documents — including paths, servers, and security — rather than only their component schemas. Enable it via CUE_EXPERIMENT=openapiv2; the underlying Go APIs are openapi.ExtractV2 and openapi.GenerateV2.

New output encoding tags: --out yaml+indentSequences=false emits the zero-indent list style favored by Kubernetes and others (#4177), and --out cue+compact or --out json+compact emit compact single-line output.

cue import now prefers hash-delimited strings like #"..."# when they avoid escaping, keeping strings with quotes or backslashes readable (#124).

The JSON Schema encoder can now generate JSON Schema draft-07 and the OpenAPI 3.0 dialect in addition to draft 2020-12. Generation is also improved in a number of ways: format keywords for sized number types (#2529), struct.MinFields and struct.MaxFields (#3605), bytes as base64-encoded strings (#1785), non-concrete comparison bounds (#3742), and distinct names for same-named references (#4277).

The ProtoBuf decoder now resolves unqualified references to types declared in proto files without a package (#4416).

cue get go now supports map keys which are integers or implement encoding.TextMarshaler (#3064), and translates fields of type cue.Value to _ (#3488).

Go API

The new cue.Unify function unifies many values at once, more efficiently than a chain of Value.Unify calls.

The new ast.DocComments and ast.ResolveComments functions report the doc comments that semantically document a node, resolving the field-shorthand convention.

The experimental jsonschema.GenerateMany function generates several schemas at once with a shared pool of definitions, as used by the new OpenAPI generator.

cue.Context.Encode now honors the omitzero JSON struct tag (#4429), and renders multi-line strings from json.Marshaler values as CUE multi-line strings (#3578).

tools/flow now supports tasks in a value below the root of its instance (#2185), and a data race in the task runner has been fixed (#2184).

Fix a panic in Value.Subsume involving validators with unevaluated arguments (#4387), and fix sub-values not being associated with their enclosing package instance (#2577).

The Go code generated from cue.proto is now shipped as the encoding/protobuf/cueproto package, so proto definitions using CUE options can be compiled without extra setup (#581). The compatibility shim at encoding/protobuf/cue is deprecated and will be removed in v0.19.
