Claro v1.18.26 Current Status

This file is the beginner-safe status map for the current package. It separates what is ready to use from what is historical, experimental, or still planned.

How to read the status labels

• Stable foundation: good enough for normal examples and beginner learning.
• Foundation present: usable, but still missing important polish or coverage.
• Experimental/planned: do not rely on it in beginner lessons yet.
• Historical: kept for release history, not current instructions.

Feature matrix

Beginner scripting core

Status: Stable foundation

Ready now:

• variables with SET
• output with SAY
• input with ASK
• choices with IF / ELSE / END
• loops
• lists and maps
• files, JSON, text helpers, and tested path/collection library helpers
• friendly checking with claro check

Good starting docs:

• QUICK_START.md
• FIRST_HOUR.md
• CLI.md
• SPEC.md

Functions

Status: Stable foundation

Ready now:

• simple modern form: TEACH name arg ... END
• compatibility form: TEACH name TAKES arg ... LEARNED
• calls with DO or older CALL ... WITH

Good starting docs:

• SIMPLE_FUNCTIONS.md
• README.md

Static type safety

Status: Foundation present

Ready now:

• typed variables such as SET score NUMBER 10
• TYPE OF and CHECK TYPE
• typed list/map checks through claro typecheck, including a nested LIST OF MAP insertion example
• a narrow function/method argument check: CHECK TYPE parameter IS TYPE inside a function or simple object method lets claro typecheck accept correct checked calls, catch mismatched DO, CALL ... WITH, DO object.method ..., and compatibility CALL object.method WITH ... arguments, including checked methods that appear after another method in the same class, report missing checked function and method arguments, report missing unchecked arguments for simple functions and simple object methods, treat empty compatibility calls such as CALL greet WITH as missing-argument mistakes, catch extra arguments to simple functions and checked methods even when the checked method appears after another method in the same class, catch modern DO and compatibility CALL ... WITH calls to undeclared simple functions, explain when DO object.method ... or compatibility CALL object.method WITH ... happens before the object is created with NEW even if the method name is also wrong, and catch modern plus compatibility calls to undeclared object methods with a class-specific TEACH hint
• a narrow object-field assignment/check-type check for simple NEW Class object plus direct SET object.field value and CHECK TYPE object.field IS TYPE cases when the class declares HAS field TYPE; validation now covers correct NUMBER, TEXT, and YESNO direct assignments, explicitly typed field assignments, simple and chained object aliases for both field assignments and CHECK TYPE metadata (including a chained TEXT-field check), aliased object-method calls including chained aliases in modern DO and compatibility CALL ... WITH forms (with a dedicated positive modern DO chained-alias fixture), field-to-field, compound arithmetic field expressions, and arithmetic/text expression result types, direct CHECK TYPE metadata acceptance for NUMBER/TEXT/YESNO fields, negative NUMBER/TEXT/YESNO field CHECK TYPE metadata mismatches, NUMBER/TEXT/YESNO-expectation unknown-field CHECK TYPE diagnostics, missing-object field assignment and CHECK TYPE diagnostics, NUMBER/TEXT/YESNO wrong-type diagnostics, field collection when a HAS field appears after a simple method, NUMBER/TEXT/YESNO-valued unknown-field diagnostics for direct assignments to undeclared fields, numeric and text results from simple arithmetic/text expressions in object-field assignments, plus a plain beginner-facing unknown-field diagnostic when the assigned expression type is not inferable yet

Still needed:

• Keep the focused typecheck validator's fixture list complete as new positive and negative examples are added.
• The expression checker now carries a known TEXT operand through all arithmetic operators so object-field diagnostics do not hide subtraction, multiplication, or division mistakes; focused numeric-division and numeric-multiplication positives plus text-operand subtraction, multiplication, and division negatives protect this behavior, while operator-specific diagnostics remain planned.
• richer typed function signatures and return values
• type checking through branches and loops
• richer object field type checking beyond simple direct assignments
• typed imports/modules

Good starting docs:

• ADVANCED_STATIC_TYPING.md
• V1_14_STATIC_TYPES.md (feature history plus examples)

Objects and classes

Status: Foundation present

Ready now:

• CLASS
• typed HAS fields
• NEW
• field access such as player.score
• simple methods, including static diagnostics for checked method parameters
• direct object-field assignments with a narrow static diagnostic for wrong value types
• object helper commands

Still needed:

• broader object field type checking across aliases, methods, and more complex object flows
• constructor/default-value polish
• clearer object debugging and teaching examples

Good starting docs:

• V1_15_OBJECTS_CLASSES.md
• README.md

Package and project workflow

Status: Foundation present

Ready now:

• claro new
• claro package init
• claro package add/list/remove/doctor/lock
• local project files such as claro.project, claro.lock, and packages/
• starter projects from claro new now use the same manifest-version and lock-version headers as claro package init
• project-name safety checks for claro new, so unsafe names such as ../bad are rejected before Claro creates folders
• package-name safety checks when adding packages, including the 64-character package-name limit, when claro package doctor audits an existing claro.project, when claro package lock writes lockfile data, when claro package list shows existing packages, when claro package init sees unsafe names already present in claro.project, when claro package add sees unsafe names already present in claro.project, when claro package remove refreshes the lockfile after an edit, when learners need to remove an unsafe package entry that is already present, when claro package doctor verifies lockfile checksums for listed packages, and when claro package doctor rejects lockfile package entries that are not listed in claro.project
• claro package doctor rejects a listed package manifest whose name: does not match the package name in claro.project
• claro package doctor compares the complete manifest name: value, so a prefix such as math-tools-extra cannot be accepted for package math-tools
• claro package doctor requires exactly one complete supported package manifest-version: 1 field; missing, blank, unsupported, or duplicate format fields get a BAD package manifest version diagnostic with the file path and a repair hint, rather than calling an existing file missing
• claro package doctor compares the complete manifest checksum: value, so a valid checksum followed by extra text is rejected
• claro package doctor requires the complete supported manifest-version: 1 value in claro.project, so a prefix such as manifest-version: 10 is rejected
• claro package doctor requires the complete supported version: 1 value in each local package manifest, so a prefix such as version: 10 is rejected
• claro package doctor requires exactly one current version: v1.18.26 line in claro.lock, so stale, missing, blank, or duplicate lockfile release versions are rejected
• claro package doctor requires the complete supported source: local value in each local package manifest, so a prefix such as source: local-extra is rejected
• package project entries must be unique; claro package doctor, list, add, init, and lock reject duplicate names instead of generating ambiguous package or lockfile data
• lockfile package entries must also be unique; claro package doctor reports duplicate lock entries instead of accepting ambiguous package/checksum data
• package manifest name: entries must also be unique; claro package doctor reports BAD package manifest name instead of accepting ambiguous package identity data
• package manifest checksum: entries must also be unique; claro package doctor reports BAD package checksum instead of accepting ambiguous integrity data
• package manifest version: entries must also be unique and must contain exactly 1; claro package doctor reports BAD package version instead of accepting ambiguous package metadata
• project manifests must contain exactly one manifest-version: 1 field; duplicate or prefix-matching values are rejected with BAD project manifest version: expected 1
• project manifests must contain exactly one non-empty name: field; claro package doctor reports BAD project manifest name: expected a non-empty name when the project identity is missing or blank

Still needed:

• install from local path
• package version constraints
• publish/export format
• remote registry protocol
• checksum/signature verification before downloads

Good starting docs:

• V1_16_PACKAGES_PROJECTS.md
• PACKAGE_REGISTRY.md

Networking

Status: Foundation present

Ready now:

• beginner HTTP commands
• offline claro:// URLs for tests and lessons
• LASTHTTP
• real http:// and https:// through curl when available

Still needed:

• web server syntax
• routes
• request/response helpers
• localhost-safe server mode

Good starting docs:

• V1_17_NETWORKING.md
• WEB_SERVER_PLAN.md

Concurrency and tasks

Status: Foundation present

Ready now:

• deterministic task/concurrency helpers where documented
• beginner-safe direction toward cooperative tasks

Still needed:

• full cooperative scheduler semantics
• cancellation
• timeouts
• message passing
• decision on whether native threads should ever be exposed

Good starting docs:

• CONCURRENCY.md

IDE/editor support

Status: Foundation present

Ready now:

• claro ide
• metadata JSON
• completion list
• diagnostics helper
• Forgejo/Gitea CI coverage for the current release validation gates (claro validate, typecheck diagnostics validation, version convention validation, package security validation, and the CI workflow coverage check); the workflow validator verifies these commands, including its own command, occur in executable run steps rather than comments

Still needed:

• syntax highlighting package
• editor extension
• hover help
• go-to-definition
• code actions/fixes
• full LSP server if/when useful

Good starting docs:

• IDE.md
• EDITOR_EXTENSION_PLAN.md

Graphics and SDL

Status: Experimental/planned

Ready now:

• placeholder/planned graphics documentation
• experimental examples may exist for future SDL work

Not ready in the stable executable:

• real SDL window/drawing support
• beginner game lessons that run everywhere

Good starting docs:

• GRAPHICS.md
• SDL12.md

Historical docs

Files named RC*_NOTES.md, RC*_VALIDATION.md, older V1_*_VALIDATION.md, and older release notes are kept for project history. They may mention old version numbers, old planned milestones, or old validation scripts. Use them to understand how Claro evolved; do not treat them as the current beginner path.

Which docs should a new learner trust first?

For the current v1.18.26 package, read docs in this order:

1. QUICK_START.md, FIRST_HOUR.md, and lessons/README.md for first programs.
2. README.md and this file for the current feature map.
3. ROADMAP.md for the next v1 work.

Use feature docs with these expectations:

• Ready for beginner lessons: SPEC.md, SIMPLE_FUNCTIONS.md, ERRORS.md, LINTER.md, TESTING.md, FORMATTER.md.
• Foundation present: ADVANCED_STATIC_TYPING.md, V1_14_STATIC_TYPES.md, V1_15_OBJECTS_CLASSES.md, V1_16_PACKAGES_PROJECTS.md, V1_17_NETWORKING.md, CONCURRENCY.md, IDE.md.
• Plans or experiments: PACKAGE_REGISTRY.md, WEB_SERVER_PLAN.md, EDITOR_EXTENSION_PLAN.md, GRAPHICS.md, SDL12.md, COMPLETE_PLATFORM_ROADMAP.md, FUTURE_FEATURES_ROADMAP.md.

If a doc sounds more ambitious than this status map, treat this file as the current source of truth and update the older doc before teaching from it.
