From 96a7da3ab3ecc1f60b39da8e4bb22536f235f770 Mon Sep 17 00:00:00 2001 From: alexey1312 Date: Wed, 25 Feb 2026 10:48:13 +0500 Subject: [PATCH 01/13] feat(cli): W3C DTCG v2025.10 compliance for color, asset, typography export Refactor W3CTokensExporter to support v2025 and v1 (legacy) versions: - Color $value uses structured color objects (colorSpace, components, alpha, hex) - Multi-mode colors use $extensions.com.exfig.modes - Assets use $extensions.com.exfig.assetUrl instead of invented $type: "asset" - Typography decomposed into sub-tokens (fontFamily, fontSize, lineHeight, letterSpacing) - Add --w3c-version v1|v2025 flag (default: v2025) to all download commands - Add ColorTokenMetadata for Figma variableId/fileId in $extensions - V1 preserves all legacy behavior for backward compatibility Implements tasks 1.1-1.7, 2.1-2.5, 4.1-4.3, 6.1-6.7 from w3c-tokens-v2 change.

When tokensFile is set on a colors entry, the pipeline reads from a local .tokens.json file instead of Figma API. Includes codegen, bridging, validation, and integration tests.

Error handling: add depth limit (10) to ColorsVariablesLoader.handleColorMode to prevent stack overflow on circular aliases, warn about skipped sections in `download tokens` with error on empty output, distinguish depth-exceeded from unresolved in NumberVariablesLoader via ResolveResult enum, warn on non-string fontFamily entries and unexpected $deprecated types, warn when local tokens file ignores mode config. Type safety: make NumberToken.variableId/fileId optional (String?), conditionally emit $extensions in W3C exporter, make insertToken private. Docs: fix $extends claim (not implemented, now emits warning), fix colorToHex doc RGBA→RGB, remove 13 Task X.Y references, fix --output required→optional in DocC, fix NumberToken location in CLAUDE.md, fix MEMORY.md scope classification. Code quality: simplify scopesToTokenType, remove basePath alias, replace test deepMerge helper with production mergeTokens, add swiftlint:enable file_length to W3CTokensExporter. --- README.md | 2 +- .../Context/ColorsExportContextImpl.swift | 7 + Sources/ExFigCLI/ExFig.docc/Usage.md | 2 +- Sources/ExFigCLI/Input/TokensFileSource.swift | 122 +++++++++++++----- .../Colors/ColorsVariablesLoader.swift | 11 +- .../Loaders/NumberVariablesLoader.swift | 59 +++++---- .../ExFigCLI/Output/W3CTokensExporter.swift | 38 +++--- .../ExFigCLI/Subcommands/DownloadTokens.swift | 37 +++++- .../ExFigCLI/TerminalUI/ExFigWarning.swift | 9 ++ .../TerminalUI/ExFigWarningFormatter.swift | 12 +- Sources/ExFigCore/CLAUDE.md | 1 - .../Output/W3CTokensExporterTests.swift | 26 +--- 12 files changed, 218 insertions(+), 108 deletions(-) diff --git a/README.md b/README.md index 402de7aa..7e5988be 100644 --- a/README.md +++ b/README.md @@ -5,7 +5,7 @@ [![CI](https://github.com/alexey1312/ExFig/actions/workflows/ci.yml/badge.svg)](https://github.com/alexey1312/ExFig/actions/workflows/ci.yml) [![Release](https://github.com/alexey1312/ExFig/actions/workflows/release.yml/badge.svg)](https://github.com/alexey1312/ExFig/actions/workflows/release.yml) [![Docs](https://github.com/alexey1312/ExFig/actions/workflows/deploy-docc.yml/badge.svg)](https://alexey1312.github.io/ExFig/documentation/exfig) -![Coverage](https://img.shields.io/badge/coverage-49.36%25-yellow) +![Coverage](https://img.shields.io/badge/coverage-50.65%25-yellow) [![License](https://img.shields.io/github/license/alexey1312/ExFig.svg)](LICENSE) Command-line utility to export colors, typography, icons, and images from Figma to Xcode, Android Studio, Flutter, and diff --git a/Sources/ExFigCLI/Context/ColorsExportContextImpl.swift b/Sources/ExFigCLI/Context/ColorsExportContextImpl.swift index aac26e4e..2ae763a9 100644 --- a/Sources/ExFigCLI/Context/ColorsExportContextImpl.swift +++ b/Sources/ExFigCLI/Context/ColorsExportContextImpl.swift @@ -57,6 +57,13 @@ struct ColorsExportContextImpl: ColorsExportContext { func loadColors(from source: ColorsSourceInput) async throws -> ColorsLoadOutput { if let tokensFilePath = source.tokensFilePath { + // Warn if mode-related fields are configured but will be ignored + if source.darkModeName != nil || source.lightHCModeName != nil || source.darkHCModeName != nil { + ui.warning( + "Local tokens file provides single-mode colors only" + + " — darkModeName/lightHCModeName/darkHCModeName will be ignored" + ) + } return try loadColorsFromTokensFile(path: tokensFilePath, groupFilter: source.tokensFileGroupFilter) } return try await loadColorsFromFigma(source: source) diff --git a/Sources/ExFigCLI/ExFig.docc/Usage.md b/Sources/ExFigCLI/ExFig.docc/Usage.md index 08167100..be9ca515 100644 --- a/Sources/ExFigCLI/ExFig.docc/Usage.md +++ b/Sources/ExFigCLI/ExFig.docc/Usage.md @@ -225,7 +225,7 @@ exfig download all -o ./tokens/ | Option | Short | Description | Default | | ---------------- | ----- | -------------------------------- | ------- | -| `--output` | `-o` | Output file path (required) | - | +| `--output` | `-o` | Output file path | varies | | `--format` | `-f` | Output format: w3c, raw | w3c | | `--compact` | - | Output minified JSON | false | | `--asset-format` | - | Image format: svg, png, pdf, jpg | svg | diff --git a/Sources/ExFigCLI/Input/TokensFileSource.swift b/Sources/ExFigCLI/Input/TokensFileSource.swift index 3392e884..f55b5186 100644 --- a/Sources/ExFigCLI/Input/TokensFileSource.swift +++ b/Sources/ExFigCLI/Input/TokensFileSource.swift @@ -86,12 +86,16 @@ enum ParsedTokenValue { /// Parses W3C DTCG .tokens.json files into typed token models. /// /// Supports nested groups, `$type` inheritance, alias resolution, -/// `$root`, `$extends`, and `$deprecated`. +/// `$root`, and `$deprecated`. +/// +/// Note: `$extends` is not currently implemented (requires cross-file merge). struct TokensFileSource { /// All parsed tokens indexed by dot-path (e.g., "Brand.Primary"). private(set) var tokens: [String: ParsedToken] = [:] /// Warnings emitted during parsing (unsupported types, non-sRGB colors). private(set) var warnings: [String] = [] + /// Whether `resolveAliases()` has been called. + private(set) var isResolved = false /// Unsupported W3C token types that emit warnings. private static let unsupportedTypes: Set = [ @@ -127,7 +131,7 @@ struct TokensFileSource { return source } - // MARK: - Group Parsing (Task 8.2) + // MARK: - Group Parsing private mutating func parseGroup( json: JSONValue, @@ -137,11 +141,15 @@ struct TokensFileSource { let groupType = json["$type"]?.string ??
