v0.14.0-alpha.1 Pre-release
Pre-release

This release introduces a new error builtin, two language changes, and many fixes and optimizations for the new closedness algorithm.

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

Evaluator

error builtin

A new error builtin is added to the language, which allows users to create custom error values with a specified message.

Don't simplify validators into concrete values

A new CUE_EXPERIMENT=keepvalidators experiment is introduced, already on by default, which prevents validators from being simplified into concrete values.

X == Y and == X

Firstly, there were several bug fixes related to ==. Most notably, [int] == [int] incorrectly resolved to true. It now correctly resolves to an error.

All other changes are enabled using the @experiment(structcmp) file-level attribute.
Enabling thix experiment allows all CUE values to be compared for equality. This includes comparing structs.

The same experiment also allows a unary == to enforce that a value is a specific concrete value.

Documentation and examples will be available for the v0.14.0 release.

Other changes

⚠️ The file embedding experiment can no longer be disabled via CUE_EXPERIMENT=embed=0, having been introduced in CUE v0.10.0.

File embedding is now enabled when using the cue/cuecontext or cue/load APIs; earlier versions could not expose it via the Go API due to an import cycle.

⚠️ The topological field sorting experiment can no longer be disabled via CUE_EXPERIMENT=toposort=0, having been introduced in CUE v0.11.0.

⚠️ CUE_EXPERIMENT=cmdreferencepkg, introduced in v0.13.0 to require referencing tool packages to declare cue cmd tasks, is now on by default.

The new closedness algorithm has been adjusted to fix a number of "field not allowed" bugs, particularly in the form of regressions compared to the old evaluator.

A particularly slow part of the new closedness algorithm has been optimized, resulting in improvements of up to 10x in wall times for some projects.

cmd/cue

⚠️ cue def --strict jsonschema:, deprecated in favor of cue def jsonschema+strict: in v0.11.0, is no longer supported.

Go API

cue/load now provides module information via the new Instance.ModuleFile field.

⚠️ In order to support the above change, the mod/modfile.File.Format method has been moved to the function mod/modfile.Format: an API-breaking change but necessary to avoid a cyclic package dependency.

cue/parser gains a new Config API, which allows other packages like cue/load to properly apply the right parser options such as the CUE language version.

⚠️ In order to support the above change, the cue/parser.Config.ParseFile and cue/build.ParseFile signatures have now changed (incompatibly) to add a parser.Config argument, enabling the CUE language version to be passed through.

Fix an issue where cue.Value.Decode did not work with *math/big.Float types.

v0.13.0

This release finally enables the new evaluator by default -- the culmination of over a year's worth of work!

It also packs in lots of new features, such as support for absolute module packages, dozens of JSON Schema improvements, and a new experimental XML encoding.

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

Evaluator

The new evaluator first introduced in v0.9.0 via CUE_EXPERIMENT=evalv3 is now enabled by default! There are no remaining substantial regressions in our test suite, and the Unity corpus is almost entirely working now. Given that the new evaluator fixes dozens of bugs for many users, and is already significantly faster for the majority of CUE users, we believe it is time to turn it on by default.

We will continue to track any remaining issues for the new evaluator via the evalv3 label. If you encounter any regressions, please file a bug report. You can also revert to the old evaluator to temporarily work around bugs via CUE_EXPERIMENT=evalv3=0. See this FAQ page for more information.

We aim to resolve many of these remaining bugs in an upcoming v0.13.1 bugfix release.

An entirely new algorithm for cue trim and tools/trim has been implemented for evalv3, which resolves all known bugs when trimming CUE.

Closedness in evalv3 has been revisited to match the semantics of evalv2 much more closely, while at the same time reducing its overhead for larger configurations. This fixes most "field not allowed" regressions and improves the performance of some configurations by up to 5x. As a result, CUE_DEBUG=openinline is now removed as it is unnecessary.

Performance work for the new evaluator is ongoing; a number of changes in this release led to performance improvements of between 5% and 80% for a variety of projects. For more details, see Marcel's performance update last month.

⚠️ The new topological sort algorithm for field ordering has been tweaked to avoid becoming too slow in some cases. This may result in some ordering changes, but we expect them to be relatively small. See the change for more details.

The parser now correctly allows keywords as required field labels, such as if!: _, fixing a discrepancy with the spec.

Filenames beginning with a dot can now be embedded as long as the glob pattern uses an explicit dot, such as @embed(glob="dir/.data_*.json").

⚠️ @embed(glob="pattern...") directives whose file globbing results in zero files now result in an error, to avoid situations where a glob pattern silently stops working as intended.

cmd/cue

Initial support for absolute packages is introduced, which allow specifying a remote package at a particular version such as cue export foo.com/data@v1.2.3 or cue vet foo.com/schema@v1.2.3 -d '#schema' data.yaml without requiring a CUE module file locally.

The cue help filetypes logic, written itself in CUE, no longer requires using the evaluator to parse CLI arguments or load CUE packages. This results in significant speed-ups when using the CLI with many inputs.

The new cue refactor imports command rewrites import paths, making it easy to migrate between module locations and major versions.

The new cue mod mirror command copies modules from one registry to another.

cue mod tidy now preserves the top-level custom field as intended.

Hidden files, and files with build tags, should now be correctly filtered when loading a single CUE package.

cue get go should no longer attempt to import types from the Go standard library as CUE, which caused errors.

cue get go no longer fails on Go strings containing certain character escape sequences or non-UTF8 bytes.

cue get go now interprets Go fields with the new json:",omitzero" struct tag as CUE optional fields.

cue cmd now fails if no tasks were actually defined, to avoid situations where a user is misled into thinking a task was defined when it was not.

Encodings

The XML "Koala" encoding proposed in February is now available via an experimental implementation. Try it out via the CLI like cue export xml+koala: data.xml, or via its Go API.

The encoding/jsonschema package gains better support for Kubernetes schemas (CRDs and the core API) although these improvements are as yet only available via the Go API.

⚠️ The JSON Schema decoder now imports schema descriptions as CUE doc comments, which required a change to encoding/jsonschema.Config.DefineSchema.

Empty YAML files are now decoded as *null | _ rather than null, allowing them to be unified with struct schemas as if they were an empty struct.

cue exp gengotypes now allows control over how to generate optional CUE fields via e.g. @(,optional=nullable), where the default now is not to use pointers.

⚠️ cue exp gengotypes tweaks how it parses @(,type=) options to support composite types such as slices and maps. Note that this means package paths with slashes must be quoted now.

Builtins

⚠️ The uuid.ToString function is removed, given that it never did anything useful and could mislead users into thinking it did.

tool/http gained a followRedirects option to let the user disable HTTP redirection.

Go API

⚠️ CUE_EXPERIMENT=decodeint64 can no longer be disabled as we consider the experiment finished, having been introduced in CUE v0.11.0.

⚠️ The long-deprecated cue.Runtime methods Parse, FromExpr, CompileFile, and CompileExpr are now removed.

cuecontext.EvalDefault still pointed to the old evaluator; it now correctly points to the new evaluator, and follows the CUE_EXPERIMENT=evalv3 flag just like cmd/cue and the rest of the Go API.

Mirroring cuecontext.EvalExperiment, the new cuecontext.EvalStable constant is added to track the latest stable version of the evaluator.

module.SplitPathVersion and module.ParseImportPath have been deprecated in favor of cue/ast.SplitPackageVersion and cue/ast.ParseImportPath package to consolidate the API.

The new mod/modfile.File.ModuleForImportPath function allows resolving a module and default major version for a package without consulting a registry.

The new mod/modregistry.Client.Mirror method implements the logic behind the new cue mod mirror command.

The new mod/module.Version.Compare method is added in favor of module.Sort, which is now deprecated.

v0.13.0-rc.1 Pre-release
Pre-release

This release adds further fixes to the new evaluator, and speeds up the CLI when there are many inputs.

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

Evaluator

The new evaluator is improved to fix more regressions which led to incorrect errors. Since the last alpha release, two newly added projects to Unity now succeed with evalv3, and we have resolved eight issues reported on GitHub.

We also fix a bug where anonymous CUE files, such as those without a package clause, did not properly report unused import errors.

cmd/cue

The cue help filetypes logic, written itself in CUE, no longer requires using the evaluator to parse CLI arguments or load CUE packages. This results in significant speed-ups when using the CLI with many inputs.

Fix a bug where some errors shown to the user did not use relative paths to CUE files or directories as expected.

Go API

⚠️ CUE_EXPERIMENT=decodeint64 can no longer be disabled as we consider the experiment finished, having been introduced in CUE v0.11.0.

Fix a recent regression where using os.Getwd alongside the ./cmd/cue/cmd API had stopped working as it did before.

Encodings

cue exp gengotypes now allows control over how to generate optional CUE fields via e.g. @(,optional=nullable), where the default now is not to use pointers.

⚠️ cue exp gengotypes tweaks how it parses @(,type=) options to support composite types such as slices and maps. Note that this means package paths with slashes must be quoted now.

v0.13.0-alpha.4 Pre-release
Pre-release

This release adds further fixes and optimizations to the new evaluator, and introduces an experimental XML encoding for CUE.

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

Evaluator

The new evaluator is improved to fix a few more regressions which led to incorrect errors. Since the last alpha release, one more project in Unity is fully working with evalv3, and just one remains with a breakage compared to evalv2.

Performance work for the new evaluator is ongoing; a number of changes in this release led to performance improvements of between 5% and 70% for a variety of projects. For more details, see Marcel's last performance update.

As a reminder, the old evaluator is still accessible via CUE_EXPERIMENT=evalv3=0. If you encounter any errors or other problems, please file an issue with details.

Filenames beginning with a dot can now be embedded as long as the glob pattern uses an explicit dot, such as @embed(glob="dir/.data_*.json").

⚠️ @embed(glob="pattern...") directives whose file globbing results in zero files now result in an error, to avoid situations where a glob pattern silently stops working as intended.

⚠️ The CUE_DEBUG=openinline evaluator debug flag is removed, now that evalv3's closedness implementation closely matches the semantics of evalv2.

cmd/cue

cue mod tidy now preserves the top-level custom field as intended.

cue get go now interprets Go fields with the new json:",omitzero" struct tag as CUE optional fields.

cue cmd now fails if no tasks were actually defined, to avoid situations where a user is misled into thinking a task was defined when it was not.

Builtins

⚠️ The uuid.ToString function is removed, given that it never did anything useful and could mislead users into thinking it did.

tool/http gained a followRedirects option to let the user disable HTTP redirection.

Encodings

The XML "Koala" encoding proposed in February is now available via an experimental implementation. Try it out via the CLI like cue export xml+koala: data.xml, or via its Go API.

v0.13.0-alpha.3 Pre-release
Pre-release

This release fixes a handful of bugs in the new evaluator and its Go API.

Evaluator

The new evaluator, now enabled by default since v0.13.0-alpha.2, is improved to fix regressions in OpenAPI, our CUE Go API, two panics, and a few other bugs which could lead to incorrect errors. Since the last alpha release, two more projects in Unity are fully working with the new evaluator.

As a reminder, the old evaluator is still accessible via CUE_EXPERIMENT=evalv3=0. If you encounter any errors or other problems, please file an issue with details.

Go API

cuecontext.EvalDefault still pointed to the old evaluator; it now correctly points to the new evaluator, and follows the CUE_EXPERIMENT=evalv3 flag just like cmd/cue and the rest of the Go API.

Mirroring cuecontext.EvalExperiment, the new cuecontext.EvalStable constant is added to track the latest stable version of the evaluator.

v0.13.0-alpha.2 Pre-release
Pre-release

This release enables the new evalv3 evaluator by default, and introduces initial support for absolute packages.

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

Evaluator

⚠️ The new evaluator is now enabled by default, given that the majority of our test suite and projects in Unity are now working. While a few regressions remain, dozens of bugs are fixed by the new evaluator, and it already shows better performance by orders of magnitude on many projects.

The old evaluator is still accessible via CUE_EXPERIMENT=evalv3=0. If you encounter any errors or other problems, please file an issue with details.

For more information, see our new guide on upgrading from evalv2 to evalv3.

Closedness in evalv3 has been revisited to match the semantics of evalv2 much more closely, while at the same time reducing its overhead for larger configurations. This fixes most "field not allowed" regressions and improves the performance of some configurations by up to 2-5x.

cmd/cue

Initial support for absolute packages is introduced, which allow specifying a remote package at a particular version such as cue export foo.com/data@v1.2.3 or cue vet foo.com/schema@v1.2.3 -d '#schema' data.yaml.

cue get go no longer fails on Go strings containing certain character escape sequences or non-UTF8 bytes.

Encodings

Empty YAML files are now decoded as *null | _ rather than null, allowing them to be unified with struct schemas as if they were an empty struct.

Pre-release

This release brings a new cue trim algorithm, a performance fix for field ordering, two new commands, and many fixes.

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

Evaluator

A great deal of work has happened in the new evaluator, which can be used via CUE_EXPERIMENT=evalv3. Marcel recently posted another update on performance progress.

An entirely new algorithm for cue trim and tools/trim has been implemented for CUE_EXPERIMENT=evalv3, which resolves all known bugs when trimming CUE. Give it a try and report any issues you find.

⚠️ The new topological sort algorithm for field ordering has been tweaked to avoid becoming too slow in some cases. This may result in some ordering changes, but we expect them to be relatively small. See the change for more details.

The parser now correctly allows keywords as required field labels such as if!: _, fixing a discrepancy with the spec.

cmd/cue

The new cue refactor imports command rewrites import paths, making it easy to migrate between module locations and major versions.

The new cue mod mirror command copies modules from one registry to another.

cue get go should no longer attempt to import types from the Go standard library as CUE, which caused errors.

Hidden files and files with build tags should now be correctly filtered when loading a single CUE package.

Encodings

Loading binary files, such as via @embed(file="foo", type=binary), no longer requires the input to be valid UTF-8.

⚠️ The JSON Schema decoder now imports schema descriptions as CUE doc comments, which required a change to encoding/jsonschema.Config.DefineSchema.

Go API

⚠️ The long-deprecated cue.Runtime methods Parse, FromExpr, CompileFile, and CompileExpr are now removed.

module.SplitPathVersion and module.ParseImportPath have been deprecated in favor of cue/ast.SplitPackageVersion and cue/ast.ParseImportPath package to consolidate the API.

The new mod/module.Version.Compare method is added in favor of module.Sort, which is now deprecated.

The new mod/modfile.File.ModuleForImportPath function allows resolving a module and default major version for a package without consulting a registry.

The new mod/modregistry.Client.Mirror method implements the logic behind the new cue mod mirror command.
