v0.10.0-alpha.2 Pre-release
Pre-release

This release includes many fixes and enhancements, particularly for modules. It also starts requiring Go 1.22 or later, as Go 1.23.0 will be released very soon.

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.

Go API

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

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.

v0.9.2

This release includes a fix for a regression around CUE files without a package name, and updates the compiled-in language version to match the actual tagged version v0.9.2.

CL 1196785 fixes the cue/load logic to correctly take CUE files with out a package name into account (issue #3244).

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...

v0.9.0-rc.1 Pre-release
Pre-release

This release includes a number of fixes for issues spotted in the modules experiment now enabled by default as well as a few other fixes.

Modules

A number of changes such as CL 1195195 were made to fix a regression where CUE_EXPERIMENT=modules, now on by default since v0.9.0-alpha.5, would load every CUE package in the entire module even when only loading a single package.

CL 1195518 tweaks the structure of the module cache to be more consistent and self-explanatory.

CL 1195514 tweaks cue mod publish so that OCI reference digests are not printed by default, as they are often non-deterministic due to VCS information.

CL 1195530 fixed a regression where importing packages with an unnecessary package name qualifier would always result in an error.

Encodings

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

CL 1194494 tweaks cue mod publish so that uncommitted VCS changes outside of the module directory no longer cause a "VCS state is not clean" error.

CL 1194495 teaches our modules registry client to treat all HTTP 404 errors as "not found" to improve compatibility with some registries which seem to return invalid error codes.

As a reminder, the ongoing and planned work can be seen in the Modules Roadmap, and we continue to hold regular Modules feedback sessions.

Go API

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

Builtins

CL 1194165 fixes invalid builtin calls so that they correctly result in a "bottom" error.

CL 1194515 fixes structs.MinFields and structs.MaxFields to ignore optional fields, matching the documented behavior.

cmd/cue

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

v0.9.0-alpha.4 Pre-release
Pre-release

This release includes changes to the evaluator and modules experiments, as well as a number of other improvements and fixes.

Evaluator

Following the introduction of the new evaluator experiment in v0.8.0-alpha.2 via CUE_EXPERIMENT=evalv3, this release includes a number of fixes to known bugs in the new evaluator, as well as significant work towards supporting the new evaluator experiment via the Go API and not just cmd/cue.

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

Modules

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.

As a reminder, the ongoing and planned work can be seen in the Modules Roadmap, and we continue to hold regular Modules feedback sessions.

Go API

CL 1193759 teaches cue/format to collapse empty lists and structs to a single line for consistent formatting.

Builtins

CL 1193690 fixes math.MultipleOf as it had an incorrect implementation which could easily return bad results.

cmd/cue

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

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

v0.9.0-alpha.3 Pre-release
Pre-release

This release includes changes to the evaluator and modules experiments, as well as a number of other improvements and fixes. A special thanks to Noam Dolovich for numerous contributions to this release!

As a reminder: users can register their projects with Unity, our regression and performance testing setup. Unity is used to ensure that a project's CUE evaluations do not unexpectedly stop working or regress in performance. Adding your project to Unity not only guarantees that we will not break your tests unexpectedly, but it also helps to improve the quality of each CUE release. Follow this link to learn more about Unity, install it, or get in touch with any questions.

Evaluator

Following the introduction of the new evaluator experiment in the last alpha release via CUE_EXPERIMENT=evalv3, this release includes a few fixes to known bugs and panics in the new evaluator.

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

Modules

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.

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

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.

CLs 1193705 and 1193706 teach cue mod publish to include VCS metadata in published module versions, as described in Proposal 3057.

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

As a reminder, the ongoing and planned work can be seen in the Modules Roadmap, and we continue to hold regular Modules feedback sessions.

Encodings

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 any cmd/cue command involving 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.

As a reminder, the ongoing and planned work can be seen in the Encodings Roadmap, and we also use the #encodings channel on Slack.

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

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

Builtins

CL 1193242 teaches encoding/yaml.Unmarshal to reject trailing input, just like encoding/json.Unmarshal already did.

CL 1184631 fixes using math.MultipleOf as a validator function.

cmd/cue

CL 1193699 fixes a regression introduced in cue get go in v0.8.0-alpha.1 which caused transitive package dependencies to no longer be generated.

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.
