2.0.3

Release Notes

This is a re-release as the v2.0.2 release workflow failed.

🚀 Updates

• Temporarily disabled shallow checkouts triggering a hard error in CI until we can implement a
  better solution. This means that if you have a shallow checkout, you may see incorrect affected
  results, or Git commands may fail.
• Added more logs to moon docker prune to help debug edge cases.
• Added MOON_INCLUDE_RELATIONS environment variable support for the --include-relations CLI
  option.
• Added .env and .env.* as defaults to the hasher.ignoreMissingPatterns setting.

🐞 Fixes

• Fixed an issue where the graph visualizers would not render correctly in the VS Code extension.
• Fixed an issue where a task with shell: false would be force enabled when a glob/env was
  detected. We now respect the configured value.
• Fixed an issue where "run" type based tasks would not run in CI. You'll need to pair it with --ignore-ci-checks.

2.0.1

Release Notes

🚀 Updates

• Updated moon upgrade to upgrade via proto if we detect that moon is managed by proto. This will
  run proto install moon latest.

🐞 Fixes

• Fixed some WASM serialization errors.
• Fixed the moon upgrade command not handling the new v2 distribution format correctly. If you are
  on moon v2.0.0, the upgrade command will still be broken until you upgrade to this patch.

• Fixed task job parallelism to partition after tasks have been filtered based on affected state.
• Fixed an issue where env var substitution would not process in the order they were defined.
• Fixed an issue where ctrl+c wouldn't exit when a prompt was waiting for input.
• Fixed an issue where project based task inputs would not be reflected internally in the input
  files/globs list.
• Fixed an issue where running a task that triggers a system/moon error wouldn't output the error
  message. This also aborts the action pipeline correctly now.
• Fixed an issue where errors during project graph building would not be reported correctly.
• Fixed an issue where a negated glob in a file group would not expand properly when used as an
  argument.

    • All old "stable" toolchains have been replaced with the new "unstable" toolchains.
• VCS
  • Reworked the hooks layer for better interoperability.
• WASM API
  • Removed the /cwd virtual path.
  • Renamed ProjectFragment.alias to ProjectFragment.aliases and changed its type from
    Option<String> to Vec<String>.
  • Removed RegisterExtensionOutput.config_schema field. Use the new define_extension_config
    plugin function instead.

🚀 Updates

View the announcement blog post for all updates, new features, improvements, and much more!

• Action pipeline
  • Will now always generate a hash for a task, even if caching is disabled.
  • Applies "transitive reduction" to the graph, removing unnecessary edges for better performance.
  • Improved console output, logging, and error handling.
  • Improved parallelism when running tasks.
    • Now resolves and expands targets before partitioning.
    • Now partitions after filtering based on affected state.
• CLI
  • New commands: moon exec, moon extension, moon hash, moon projects, moon tasks,
    moon query affected, moon template
  • Updated commands moon check, moon ci, and moon run:
    • Now uses moon exec under the hood.
    • Added levels to --summary.
  • Updated commands that require an identifier to prompt for it if not provided.
  • Stabilized the moonx binary (which uses moon exec under the hood).
  • Added support for .config/moon instead of .moon.
  • Added support for ... in task targets, which is an alias for **/*. This is similar to how
    Bazel targets work.
  • Improved stack memory usage by pushing thread data to the heap. This resolves spurious stack
    overflow issues.
• Configuration
  • Added support for more formats: JSON, TOML, and HCL.
  • .moon/extensions.*
    • New file for configuring extensions (formerly in workspace.extensions).
  • .moon/tasks.*
    • Added inheritedBy setting for configuration based task inheritance.
  • .moon/workspace.*
    • Added projects.globFormat setting.
    • Added defaultProject setting.
    • Stabilized remote caching.
  • moon.*
    • Added mergeToolchains task option.
    • Added "utility" task preset.
    • Added "data" stack.
• Docker
  • Better toolchain integration.
  • Added --no-setup and --template support to moon docker file.
  • Updated project configs to override workspace configs.
• Extensions
  • Added a new extension, unpack, for unpacking archive files.
  • Added .moon/extensions.* configuration file.
  • Added support for new plugin APIs: define_extension_config, extend_command,
    extend_project_graph, extend_task_command, extend_task_script, sync_project, and
    sync_workspace.
• MCP
  • Added a generate tool for running the code generator.
• Projects
  • Added a default project concept.
  • Added path based IDs instead of dir name IDs.
  • Updated projects to support multiple aliases (one from each applicable toolchain).
• Tasks
  • Added deep merging support for task inheritance.
  • Updated command and args with better syntax parsing and error handling.
    • Better handling of quotes, escapes, and spaces.
    • Extracts env vars into the task.
  • Updated env values to support null, which would remove an inherited system env var.
  • Updated envFile option to support token/var substitution.
  • Improved .env handling:
    • Updated the parser to support more syntax.
    • Updated loading to occur before task execution, instead of creation.
    • Can now reference system/moon/task env vars for substitution.
• Toolchains
  • Stabilized the new WASM plugin system.
  • Improved how toolchains extend env vars and paths for commands and scripts.
• Tokens
  • Added new tokens: $projectTitle, $projectAliases, $taskToolchains
• VCS
  • Replaced the old v1 Git implementation with a new v2 implementation.
  • Improved support for worktrees, submodules, and more.
• WASM API
  • Added a load_extension_config_by_id host function.
  • Added define_extension_config, initialize_extension, and extend_command plugin functions.
  • Added load_extension_config, parse_extension_config and parse_extension_config_schema
    utility functions.
  • Added DefineExtensionConfigOutput, InitializeExtensionInput, InitializeExtensionOutput,
    ExtendCommandInput, and ExtendCommandOutput types.
  • Added ExtendProjectGraphInput.extension_config, ExtendTaskCommandInput.extension_config,
    ExtendTaskScriptInput.extension_config, SyncProjectInput.extension_config, and
    SyncWorkspaceInput.extension_config fields.
  • Added RegisterToolchainOutput.language field.

🧩 Extensions

• Migrate Nx
  • Added support for the following project.json fields: targets.*.continuous
• Migrate Turborepo
  • Added support for the following turbo.json fields: tags, tasks.*.env (wildcards and
    negation)
• Unpack
  • Updated to use unzip and tar commands.

🧰 Toolchains

• JavaScript
  • Added support for Yarn v4.10 catalogs.
  • Fixed an issue where implicit dependencies would sometimes not resolve.

🐞 Fixes

• Fixed local executables in @moonrepo packages not being detected correctly.
• Fixed task job parallelism to partition after tasks have been filtered based on affected state.
• Fixed an issue where env var substitution would not process in the order they were defined.
• Fixed an issue where ctrl+c wouldn't exit when a prompt was waiting for input.
• Fixed an issue where project based task inputs would not be reflected internally in the input
  files/globs list.
• Fixed an issue where running a task that triggers a system/moon error wouldn't output the error
  message. This also aborts the action pipeline correctly now.
• Fixed an issue where errors during project graph building would not be reported correctly.

⚙️ Internal

• Updated proto to v0.54.1 (from 0.53.2).
• Updated wasmtime to v37.
• Updated Rust to v1.92.0.
• Updated dependencies.
