v0.11.0-alpha.2 Pre-release
Pre-release

This release includes a new matchIf built-in validator, many more improvements to JSON Schema and TOML support, as well as some fixes.

Evaluator

CL 1200942 adds a new matchIf builtin, similar to matchN, which makes it significantly easier to implement the if, then, and else keywords in JSON Schema.

Modules

CL 1201493 gives a better error message when a module is not found.

CL 1201522 fixes a bug where imports did not work properly when using cue/load.Config.Package = "*".

Encodings

A significant amount of work has gone into improving JSON Schema support, fixing many bugs and producing better CUE output, as well as leveraging the new matchN and matchIf builtins. While this work is still in progress, we already expect an overall improvement compared to v0.10.0. This work will also form the basis for CUE modules for well-known services that will be published to the Central Registry.

CL 1200901 improves filetype tags, as described by cue help inputs, so that unknown tag=value pairs cause failures, and invalid pair combinations aren't silently ignored.

CLs 1200899 and 1200924 split JSON Schema's strictness option into StrictFeatures and StrictKeywords which allows erroring when unimplemented features are used, but not when unknown keywords are used. --strict is also superseded by jsonschema+strict:.

CL 1200932 turns on JSON Schema's new StrictFeatures option on by default, a saner default as we know which features we have not yet implemented and so the schema cannot be interpreted correctly.

CL 1201111 teaches default filetype tags to be applied in the default auto interpretation mode as well.

CL 1201113 adds the StrictFeatures and StrictKeywords options to OpenAPI, mirroring the options added to JSON Schema.

CL 1200888 adds support for decoding TOML dates and times.

Builtins

CL 1201474 adds a new encoding/toml package with Marshal and Unmarshal APIs, following the addition of TOML support in v0.10.0.

CL 1201115 removes strconv.ParseComplex, which never worked in any past CUE release and does not seem like an useful API to have in its current form.

cmd/cue

CL 1201709 fixes a minor regression introduced in CUE v0.9.0 where cue help cmd mycmd ./mypkg stopped showing a valid command's help text.

v0.11.0-alpha.1 Pre-release
Pre-release

This release includes a new matchN built-in validator, many fixes for the new evaluator, and a significant amount of work on JSON Schema.

Evaluator

A number of crashes, regressions, and other bugs have been fixed in the new evaluator, which can be enabled by CUE_EXPERIMENT=evalv3. For more details, see our latest performance update. Thanks to all who have tested the new evaluator and reported bugs!

CL 1198922 adds a new matchN built-in validator, necessary implement a host of validators such as the JSON Schema equivalents of not, oneOf, and anyOf. See the new how-to guide for it.

CL 1199898 relaxes the evaluator to allow referencing required fields via selectors, rather than failing like we do with optional fields. This should help with the transition of CUE schemas from regular to required fields, such as those decoded from JSON Schema.

CL 1200221 removes support for arithmetic operators on lists, and CL 1200221 teaches cue fix to rewrite most of them. We have added a doc page with more details and examples.

CL 1199684 teaches the evaluator to allow non-concrete values to be passed as parameters to certain builtin functions such as yaml.Validate.

CL 1199723 deduplicates errors when pairwise-combining them, as the duplication could result in large memory usage.

Modules

CL 1199541 wraps up the CUE modules experiment by dropping support for CUE_EXPERIMENT=modules=0, now that the new mode has been the default since CUE v0.9.0, and we are not aware of any remaining regressions.

Go API

CL 1200507 deprecates astutil.Cursor.Import, which is now superseded by astutil.Sanitize.

Encodings

A significant amount of work has gone into improving JSON Schema support, fixing many bugs and producing better CUE output, as well as leveraging the new matchN builtin. While this work is still in progress, we already expect an overall improvement compared to v0.10.0. This work will also form the basis for CUE modules for well-known services that will be published to the Central Registry.

CL 1199938 teaches the TOML decoder to produce CUE nodes with positions, allowing errors to include positions within TOML files.

CL 1199541 wraps up the new YAML decoder experiment by dropping support for CUE_EXPERIMENT=yamlv3decoder=0, allowing the 8400 lines of code in internal/third_party/yaml to be removed.

Builtins

CL 1194425 tweaks the yaml.Validate and json.Validate functions to allow non-concrete CUE values as schema parameters.

CL 1199602 adds a list.MatchN function, surfacing the matchN built-in validator for use in the JSON Schema decoder.

CL 1199881 tweaks uuid.Valid so that it is consistent with uuid.Parse in terms of what UUID formats are accepted.

cmd/cue

CL 1199634 drops support for the deprecated short form of cue cmd; users of cue foo should now call cue cmd foo.

CL 1200351 fixes a bug in cue fix where it would not operate on directories with multiple packages.

CL 1200498 fixes a bug in cue fix where added imports would end up with mangled names.

CL 1200554 teaches cue fix to work on standard input and output, like other sub-commands.

v0.10.0 Latest

This release includes experimental support for the embed proposal, many fixes for the new evaluator and modules, as well as many other fixes and enhancements.

Evaluator

CLs 1195897, 1196094, 1198356, 1198736, and 1198860 fix crashes with CUE_EXPERIMENT=evalv3 as reported by users.

CLs 1199272, 1199273, and 1199340 fix spurious "field not allowed" error regressions in the new evaluator.

CL 1198566 fixes a performance regression introduced in CUE v0.6 where cue cmd and tools/flow became many times slower on some inputs.

CL 1198350 ensures that all interpreter errors, such as those from @embed attributes, include position information.

Embed proposal

With CUE_EXPERIMENT=embed, CUE now supports the embedding of non-CUE files within a CUE package. See the embed proposal and its design document for details, as well as the new how-to guide for the feature.

Modules

The cue help documentation for modules and inputs has been expanded, and a number of error messages when using or publishing modules are now more helpful.

A new concept guide on CUE language versions documents the language.version field in cue.mod/module.cue files.

CL 1198249 adds support for an @ignore file attribute to unconditionally ignore a file when loading packages or calculating dependencies.

CL 1198003 teaches the CUE loader to support symbolic links when loading from local directories, matching the behavior before CUE_EXPERIMENT=modules was introduced.

CL 1198143 tweaks cue mod init without an argument to create a module with the module path cue.example rather than an empty path that made the module file invalid.

CL 1197530 fixes the behavior of build tags, and also adds support for parentheses in build tag expressions.

CL 1197531 implements better caching when evaluating dependencies, which should speed up evaluation of modules that use multi-directory packages.

Go API

CL 1196721 disallows importing or loading packages with an underscore qualifier like foo.com/bar:_, as it was never intended behavior. Users should use the new embed proposal instead.

CL 1198555 adds a cue/load.Config.SkipImports option to avoid loading instances from import statements. This particularly helps cue fmt, where the loading caused unwanted slowness and unnecessary errors.

CL 1196820 adds a cue.LanguageVersion function to obtain the current version of the language spec that the Go module implements.

CL 1197160 implements considered support for build tags in modules. Build tags are considered false when outside the main module.

CL 1198686 fixes cue/load so that it no longer produces extra invalid packages when Config.Package was set to * and nested packages were loaded.

CL 1198351 fixes a bug in astutil.Sanitize where unused imports were not being fully removed from ast.File, causing errors in cue trim where all uses of an import were removed.

CL 1198494 speeds up the Path method on wrapped errors, which causes noticeable speed-ups in some edge cases.

CL 1198157 fixes cue/parser to accept keywords as valid selectors, aligning with the language specification.

Encodings

Initial support for TOML is included in this release, including support in cmd/cue and an experimental Go package. See the issue tracker for remaining work in this space.

CLs 1199309, 1199139, 1199306, 1199214, 1199398, 1199308, and 1199309 resolve a number of issues when decoding JSON Schema files.

CLs 1196332, 1199094, and 1199103 fix the JSON decoder to provide correct position information when decoding JSONL files or encountering a syntax error.

CL 1198874 fixes the loading of JSON files to reject multiple newline-delimited values, as those ar only allowed in NDJSON or JSONL files.

CL 1198876 teaches the YAML decoder to decode empty documents as null, aligning with the YAML spec and fixing panics when loading empty YAML files.

CL 1196291 tweaks the YAML decoder so that comments following a field are attached to the entire field.

CL 1196436 tweaks the textproto decoder to correctly handle required and optional fields.

CLs 1195628 and 1199054 ensure that cue/format prints the correct white space before and after comments.

CL 1195884 teaches cue/format to preserve comments associated with ... ellipsis expressions.

CL 538624 fixes a bug where cue/format would start a CUE file with white space if it began with a clause.

CL 1196134 fixes a bug in cue/format where a comment at the start of a CUE file would sometimes be indented.

CL 1196135 fixes a bug in cue/format where index or selector expressions could cause extra tab indentation.

Builtins

CL 1196212 adds a list.Reverse function to reverse the elements of a list.

CL 1197452 tweaks tool/exec.Run so that its errors are unambiguous when any command arguments contain white space.

CL 1198636 tweaks path.Match and tool/file.Glob to reject ** wildcard patterns as unsupported, to avoid confusion and allow future changes to their behavior. Note that this change may break uses of ** patterns, which behaved like *.

cmd/cue

CL 1196822 adds a --language-version flag for cue mod init and cue mod edit to set the language.version value.

CL 1197185 teaches cue mod resolve to work on the current module when no arguments are given.

CL 1196370 teaches cue mod registry to gracefully shut down when interrupted.

v0.10.0-alpha.1 Pre-release
Pre-release

This release includes initial support for the embed proposal, multiple fixes for the new modules support, as well as many other fixes and enhancements.

Evaluator

CLs 1195897 and 1196094 fix two crashes with CUE_EXPERIMENT=evalv3 as reported by users.

Embed proposal

With CUE_EXPERIMENT=embed, CUE now supports the embedding of non-CUE files within a CUE package. See the embed proposal and its design document for details, as well as the new how-to guide for the feature.

Modules

CL 1197530 fixes the behavior of build tags, and also adds support for parentheses in build tag expressions.

CL 1197531 implements better caching when evaluating dependencies, which should speed up evaluation of modules that use multi-directory packages.

Go API

CL 1196721 disallows importing or loading packages with an underscore qualifier like foo.com/bar:_, as it was never intended behavior. Users should use the new embed proposal instead.

CL 1196820 adds a cue.LanguageVersion function to obtain the current version of the language spec that the Go module implements.

CL 1197160 implements considered support for build tags in modules. Build tags are considered false when outside the main module.

Encodings

CL 1195628 ensures that cue/format prints a newline after every comment.

CL 1195884 teaches cue/format to preserve comments associated with ... ellipsis expressions.

CL 538624 fixes a bug where cue/format would start a CUE file with white space if it began with a clause.

CL 1196134 fixes a bug where a comment at the start of a CUE file would sometimes be indented.

CL 1196135 fixes a bug where index or selector expressions could cause extra tab indentation.

CL 1196291 tweaks the YAML decoder so that comments following a field are attached to the entire field.

CL 1196332 tweaks the JSONL (newline-delimited JSON) so that line numbers aren't reset with each new JSON value.

CL 1196436 tweaks the textproto decoder to correctly handle required and optional fields.

Builtins

CL 1196212 adds a list.Reverse function to reverse the elements of a list.

CL 1197452 tweaks tool/exec.Run so that its errors are unambiguous when any command arguments contain white space.

cmd/cue

CL 1196822 adds a --language-version flag for cue mod init and cue mod edit to set the language.version value.

CL 1197185 teaches cue mod resolve to work on the current module when no arguments are given.

CL 1196370 teaches cue mod registry to gracefully shut down when interrupted.

v0.9.1

This release includes a few fixes, mainly relating to CUE_EXPERIMENT=modules being enabled by default in v0.9.0.

Modules

CLs 1196176 and 1196180 allow using and developing a module whose cue.mod/module.cue lacks a major version suffix like @v0, as adding one may break older CUE versions without CUE_EXPERIMENT=modules.

CL 1196156 adds a cue/load.Config.AcceptLegacyModules option to allow loading CUE modules without a language.version field, given that the field was only introduced in v0.8.0.

CL 1196178 fixes a regression where loading a package with the cue/load.Config.Package option set was no longer working as expected.

As a reminder, we are maintaining an FAQ page which should help modules users with the upgrade to v0.9.

Builtins

CL 1195888 fixes the path.Match API so that it can actually take the three parameters it expects.

v0.9.0

This release includes major changes to Modules and the Evaluator, as well as many other fixes and improvements. A special thanks to Noam Dolovich for numerous contributions to this release!

Modules

Following the Modules proposal v3 being accepted, the modules experiment is now enabled by default in this release. It should no longer be necessary to set CUE_EXPERIMENT=modules, and CUE_EXPERIMENT=modules=0 can be used to disable the experiment. We are not aware of any significant regressions, so please file a bug if you find one.

We have published an FAQ page which should help modules users with the upgrade to v0.9. We will add to this page over the coming weeks to ease the transition into the "new" modules mode.

This release also includes experimental support for the CUE Central Registry at https://registry.cue.works. We have added a cue login command to log into the Central Registry via a GitHub account, and other commands know how to use these credentials when talking to the registry.

To get started with the Central Registry, we have published a tutorial on working with modules and the central registry as well. We will share more details about the Central Registry and support for other login mechanisms in the future. For now, we are looking to get early feedback.

The CUE schema for cue.mod/module.cue is now dictated by the declared language.version value, which is now mandatory. This allows us to change or tighten the schema with future CUE versions without breaking existing users. Use the new cue mod fix command to add the field.

cue mod publish now requires source to publish a module, as described in Proposal 3017. The cue mod init --source flag is added to create a new module with this field.

cue mod publish now includes VCS metadata in published module versions, as described in Proposal 3057.

The cue mod fix command is added, which allows fixing up old cue.mod/module.cue files; see cue help mod fix.

The cue mod edit command is added, which allows some automatic editing of cue.mod/module.cue from the command line; see cue help mod edit.

CL 1193289 teaches $CUE_REGISTRY about a special none registry, causing any matching modules to refuse to fetch or resolve.

CL 1195546 teaches cue mod publish to include a LICENSE file from the VCS repository root if the CUE module subdirectory has none.

CL 1194090 adds the --dryrun, --json, and --out flags to cue mod publish to inspect what would be published as part of a module version.

CL 1194106 adds the cue mod resolve command to show how a module path resolves to a registry in the form of an OCI reference.

CL 1185280 adds cue help modules as a high-level overview of CUE modules.

CL 1194669 restricts the parsing of cue.mod/module.cue files to data-only mode, forbidding any references or comprehensions which may break cue mod commands or cause other issues.

As a reminder, the ongoing and planned work can be seen in the Modules Roadmap.

Evaluator

The new evaluator can now be enabled in the command line via CUE_EXPERIMENT=evalv3, and in the Go API via cuecontext.EvaluatorVersion(cuecontext.EvalV3). The new evaluator already includes a new disjunction algorithm as well as initial structure sharing support; note that structure sharing can be disabled with CUE_DEBUG=sharing=false.

The work is not yet complete, and some known bugs remain, but over 95% of the existing tests are passing and the performance already looks promising. Work on this new evaluator will continue during the next release cycle. We will only turn on the new evaluator by default once we are reasonably confident that there are no significant regressions.

CL 1185458 ensures we detect permanent errors for undefined fields earlier, necessary for the permanent errors fix in tools/flow below.

Subscribe to the Performance umbrella issue for updates, and see the Evaluator Roadmap project for the planned work ahead.

Encodings

The Encodings project was kicked off at a recent CUE Community Update call. As part of this, we now have an #encodings channel on Slack and Discord, as well as an Encodings Roadmap project on GitHub where the ongoing and planned work can be seen.

In this release, the new YAML decoder is available in experimental form and enabled by default, given that all of our tests are already passing. You can disable it via CUE_EXPERIMENT=yamlv3decoder=0. The old YAML decoder will be removed in a future release once we're reasonably confident that no significant regressions are present.

CLs 1193257, 1193394, 1193576, and 1193577 greatly speed up internal/filetypes, used when loading files from disk in cue/load or when encoding/decoding files in cmd/cue.

CL 1193678 teaches cue/load to cache loading files from directories, which avoids repeated work when loading parent directories to form instances.

The changes above, plus cue.Value.IsNull below, should result in a significant speed-up for cmd/cue as well as cue/load when loading many CUE packages or directories. For example, on the main CUE repository, cue fmt ./... went from ~14s to ~0.1s, and cue vet ./... went from ~5s to ~2s.

CL 1193639 teaches internal/filetypes to only load its embedded CUE on first use, allowing any Go programs to skip the ~6ms load time until the first call to a cue/load API, if any.

CL 1195047 fixes the decoding of YAML 1.1 octal numbers so that they no longer result in invalid CUE literals.

cmd/cue

CL 1189314 adds a cue fmt --check flag to list badly formatted files rather than modifying them directly.

CL 1193778 adds a cue fmt --diff flag which displays diffs instead of updating files.

CL 1193962 adds a cue fmt --files flag to interpret the arguments as file paths to walk and recursively format rather than package patterns.

CL 1192180 speeds up cue fmt by ensuring that it only processes each CUE file once, rather than formatting files from parent directories as well.

CL 1185356 tweaks cue/load so that cue fmt is able to format CUE files given directly as arguments even when they belong to different packages.

CL 1193702 ensures that cue get go always generates CUE code from Go time.Duration types and values in a way that is fully compatible with Go's encoding/json library.
CL 1193386 fixes cue fmt --simplify to no longer break complex labels by unquoting string literals within them.

CL 1193934 improves cue fmt so that it does not write to files on disk which are already well formatted.

CL 1194247 tweaks cue help so that it correctly fails when given unknown help topics or commands.

CL 1185473 deprecates the short-form cue somecmd in favor of cue cmd somecmd, as the former caused a number of bugs and slowness when working out which subcommand to execute.

Go API

CL 1193405 adds a cue.Value.IsNull method to mirror cue.Value.Null without constructing error values, making cue.Value.Decode faster in many scenarios, including its use in cue/load via internal/filetypes.

CL 1191227 adds a cue/token.File.Lines getter method, much like go/token.File.Lines was added in Go 1.21.

CL 1193030 ensures that cue/load.Instances always returns instances in a deterministic order, in particular when multiple instances share the same directory.

CL 1194421 fixes a memory leak where using load.Instances to load CUE modules would increase the size of a global cue.Context until the process was terminated.

CL 1187452 teaches tools/flow to fail when a task encounters a permanent error, which were being ignored before.

CL 1191226 teaches cue/literal.ParseNum to support both positive and negative signs for consistency.

CL 1194410 fixes cue/load so that it errors on empty string arguments once again.

CL 1193515 fixes an edge case where cue/format would vertically align fields at different struct levels.

CL 1193585 fixes a bug where cue/format would print trailing commas for list elements after any inline comments, causing broken syntax.

CL 1193759 teaches cue/format to collapse empty lists and structs to a si...
