Internal Markdown links are rewritten to HTML when a matching reading page exists. Compiler Driver Alignment This document tracks the Vitte-owned compiler driver surface after the host driver migration. Overview The driver remains a first-class subsystem because it defines the stable command entrypoints that users, CI, bootstrap flows, and documentation all depend on. Concern Current contract Surface ownership src/vitte/packages/compiler/driver/* catalogs Runtime implementation src/vitte/compiler/driver/* Audit goals parity, normalization, stage mapping Enforcement dedicated make targets and strict gates Why the driver stays explicit: it defines the user-visible command surface it isolates option parsing and command dispatch from frontend/backend internals it gives CI a small, deterministic place to audit command and flag parity Responsibilities Own the visible command and flag inventory. Normalize aliases and stage names consistently. Keep package metadata and runtime implementation aligned. Invariants Command catalogs and implementation must not drift silently. Normalization rules must stay deterministic. Strict gates must detect driver regressions before release-facing changes land. Current Surface The Vitte package lives in: src/vitte/packages/compiler/driver/mod.vit src/vitte/packages/compiler/driver/info.vit src/vitte/packages/compiler/driver/internal/command_catalog.vit src/vitte/packages/compiler/driver/internal/option_catalog.vit src/vitte/packages/compiler/driver/internal/normalize.vit This package now owns: command catalog metadata top-level command inventory grammar/mod subcommand inventory flag inventory parity against the Vitte driver catalogs normalization of help aliases normalization of selected command and flag aliases stage mapping for normalized commands Data Flow User input enters through the top-level driver command surface. Package catalogs normalize commands, aliases, and selected option values. The runtime driver maps the normalized request to compiler stages. Strict audits verify that the exposed help and command behavior still match the owned catalogs. Driver Implementation The compiler driver implementation is split between the public entry facade and the runtime driver core: src/vitte/compiler/main.vit src/vitte/compiler/driver/compile.vit src/vitte/compiler/driver/compiler.vit src/vitte/compiler/driver/mod.vit src/vitte/compiler/main.vit is the real compiler entrypoint used by bootstrap and packaging flows. src/vitte/compiler/driver/compiler.vit remains the runtime command dispatcher and stage-mapping core behind that facade. Audit And Bootstrap Commands make driver-surface-audit make driver-surface-parity make selfhost-driver-bootstrap Pipeline The driver sits ahead of the compiler pipeline proper. Its job is to convert CLI surface into a precise compiler action before frontend, analysis, or backend work begins. Examples make driver-surface-audit make driver-surface-parity ./bin/vitte --help ./bin/vitte check src/app.vit Next Step Keep option value normalization aligned across the driver package and compiler driver: --template --lang --target --stage --stdlib-profile --syntax-profile --panic-budget --strict-recovery That keeps the command surface deterministic while the rest of the compiler continues moving through the Vitte source tree. 2026-05-20 Strict Gate Update Latest strict alignment pass added concrete enforcement around the driver path: make compiler-entry-lock enforces COMPILER_SOURCE_ROOT=src/vitte/compiler enforces COMPILER_ENTRY_POINT=src/vitte/compiler/main.vit make compiler-reachability-audit checks transitive module reachability from vitte/compiler/main allows temporary migration exceptions through a tracked allowlist make compiler-max-gate-strict compiler-focused strict gate (frontend/analysis/middle/backend checks + strict smokes) make selfhost-hard-strict end-to-end release gate chain for bootstrap + strict compiler path The current migration objective remains unchanged: reduce reachability allowlist to zero complete diagnostics path migration ( dignostics -&gt; diagnostics ) keep strict gates green without hidden fallback behavior 2026-05-20 Stop-After And Repro Hardening Additional strictness landed on the same date: Driver --stop-after is now treated as a hard runtime contract: stage mapping is centralized in src/vitte/compiler/driver/compiler.vit successful stop no longer rewrites final stage to Done exact stop tests now cover parse/hir/typeck/mir/ir/codegen/link/run Driver diagnostic propagation now uses typed fields end-to-end in the driver mapping la",

Documentation Source Sitemap Source Markdown Reading mode This page is the static HTML reader for bootstrap_contracts.md . Internal Markdown links are rewritten to HTML when a matching reading page exists. Bootstrap Contracts This page is the index for the bootstrap-native contract surface. Overview Bootstrap contracts are split across artifacts, readable specs, snapshots, and gates so that a contributor can understand both the human intent and the exact machine-checked surface. Contract area Primary reference Seed trust chain docs/bootstrap_seed.md Native IR format docs/bootstrap_native_ir.md Snapshot evidence tests/bootstrap_native/README.md Full local gate make bootstrap-native-contract Fast local gate make bootstrap-native-fast-contract Seed trust chain: docs/bootstrap_seed.md Native IR contract: docs/bootstrap_native_ir.md Bootstrap-native snapshots: tests/bootstrap_native/README.md Local full contract target: make bootstrap-native-contract Local fast contract target: make bootstrap-native-fast-contract CI job: bootstrap-native-contract The bootstrap contract is intentionally split across readable docs, checked seed artifacts, deterministic snapshots, and visible CI steps. A change that affects the seed parser, generated shell backend, command behavior, or canonical compiler entry must carry the matching snapshots in the same change. Responsibilities Keep bootstrap trust boundaries obvious during reviews. Point contributors to the right contract document for each bootstrap layer. Tie source edits to the exact gates that defend them. Invariants Seed, IR, generated shell behavior, and snapshots must move together. A change to the bootstrap surface without updated evidence is considered incomplete. The fast local gate may optimize execution time, but not reduce the contract coverage it claims to represent. Pipeline The bootstrap-native path connects documentation to executable verification: The seed and native IR specs describe the accepted surface. Bootstrap sources and generated artifacts produce deterministic outputs. Snapshot suites pin those outputs. CI and local make targets enforce the contract continuously. Driver Bootstrap is exposed through the driver surface as much as through compiler internals, so driver behavior changes must be considered part of this contract. Data Flow Review starts from the seed and IR docs. Source edits update seed, stage, or emitted shell behavior. Snapshots and contract targets confirm that the visible bootstrap output still matches the documented rules. Examples make bootstrap-native-fast-contract make bootstrap-native-contract tools/bootstrap_native_fixture_matrix.sh These commands are useful in combination: the fast target gives a quick signal, the full contract target verifies the whole native chain, and the fixture matrix shows whether the touched bootstrap form is already covered by a snapshot. PR Checklist Before publishing a bootstrap-native change: Run make bootstrap-native-contract . Run make docs-paths-check . Run make bootstrap-contracts-index-check . Run tools/bootstrap_native_fixture_matrix.sh and confirm the touched surface is covered by snapshots. If toolchain/seed/vittec0.seed changed, confirm toolchain/seed/manifest.txt changed with the new SHA-256. If generated shell behavior changed, confirm the relevant shell.*.must snapshots under tests/bootstrap_native/ changed with it. If parser or diagnostic behavior changed, confirm at least one .ir.must or .err.must snapshot changed with it. ← Previous Next → bootstrap_contracts.html Back to home · Public status",

Internal Markdown links are rewritten to HTML when a matching reading page exists. Bootstrap Migration Checklist The numbered-stage bootstrap has been retired. This checklist records the remaining path from a seed-rooted bootstrap to autonomous self-hosting. Overview Bootstrap trust, compiler generation, and official self-host completion are separate contracts. The seed path is complete; autonomous compiler generation is still in transition. Responsibilities Keep the seed manifest and executable synchronized. Reject fallback compilers and retired bootstrap paths. Report self-hosting gaps instead of treating transition output as complete. Invariants Only the manifest-pinned seed may initialize bootstrap execution. All bootstrap gates are blocking and deterministic. Full self-hosting requires parity and removal of every transition bridge. Data Flow vittec0.seed installs bin/vittec0 , which validates and builds the canonical compiler entry. Generated compilers rebuild that same entry only inside the self-host completion audit. Completed Checked: Pin toolchain/seed/vittec0.seed with a manifest and reviewed source. Checked: Declare a single seed item in toolchain/bootstrap-config.json . Checked: Remove numbered stage sources and bootstrap scripts. Checked: Remove active build, test, CI, release, install, and package references to numbered stages. Checked: Make missing or invalid seed state fatal with no compiler fallback. Checked: Run bootstrap CI gates as blocking jobs. Checked: Verify deterministic seed installation, IR, and native fixture emission. Checked: Keep the repository host-source audit free of bootstrap exceptions. Remaining Open: Remove the transition bridge from generated compiler payloads. Open: Obtain byte-identical successive compiler generations. Open: Compile the full compiler, runtime, and standard library with the generated compiler without delegating to the seed or a host compiler. Open: Validate every supported object, archive, executable, and cross-target format through dedicated platform gates. Open: Make python3 tools/selfhost_completion_audit.py --strict-complete pass. Required Evidence make seed-verify make bootstrap-source-of-truth make bootstrap-vitte-hard-gate make bootstrap-verify toolchain/test_bootstrap_reproducibility.sh python3 tools/selfhost_completion_audit.py --strict-complete The first four commands prove the current seed-rooted bootstrap contract.

Documentation Source Sitemap Source Markdown Reading mode This page is the static HTML reader for bootstrap_native_ir.md . Internal Markdown links are rewritten to HTML when a matching reading page exists. Bootstrap Native IR v1 native_ir_v1 is the textual intermediate representation used by the bootstrap-native seed compiler for the early build-native path. It is small by design: the format describes only the compiler identity strings, optional named string constants, and the native process exit code needed by seed-generated fixtures and compiler payloads. The canonical implementation is toolchain/seed/vittec0.seed . Golden coverage lives in tests/bootstrap_native . native_ir_v1 is the stable bootstrap contract. The shell emitted by build-native is the current POSIX bootstrap backend, not the IR contract itself. The backend may be replaced later as long as native_ir_v1 snapshots and documented command behavior remain stable. Versioning native_ir_v1 is additive-only. New records or accepted source forms may be added when older v1 readers can ignore or reject them safely under the existing fail-closed rules. Any breaking format change must use a new first-line tag, starting with native_ir_v2 . Breaking changes include changing the meaning of an existing record, removing a required record, changing record order requirements, or changing diagnostics in a way that v1 snapshots can no longer defend. native_ir_v1 snapshots remain authoritative as long as seed artifacts read or emit v1. Introducing a future v2 must keep v1 snapshots and drift checks until the stage0 trust root no longer depends on v1. Format The IR is UTF-8 text with LF line endings. The first line is the version tag: native_ir_v1 Remaining lines are key/value records: const.string.&lt;NAME&gt;=&lt;string value&gt; const.int.&lt;NAME&gt;=&lt;integer&gt; proc.int.&lt;name&gt;=&lt;integer&gt; version_text=&lt;string value&gt; banner_text=&lt;string value&gt; main.return=&lt;integer&gt; Rules: const.string.&amp;lt;NAME&amp;gt; records are optional and appear in source declaration order. const.int.&amp;lt;NAME&amp;gt; records are optional and appear in source declaration order with string constants. proc.int.&amp;lt;name&amp;gt; records are optional and appear in source declaration order. In v1 they are record-only: generated shell compilers do not expose these procedures as callable commands yet. NAME is an uppercase bootstrap constant identifier: [A-Z_][A-Z0-9_]* . version_text , banner_text , and main.return appear exactly once. String values are the decoded contents of bootstrap string literals. The v1 subset does not support escapes or embedded double quotes. Integer values are signed decimal integers. main.return is a signed decimal integer. If no supported main procedure is present, it defaults to 0 . Example: native_ir_v1 const.string.VERSION_TEXT=vittec native fixture 0.1.0 const.string.BANNER_TEXT=vittec native fixture const.int.EXIT_CODE=0 version_text=vittec native fixture 0.1.0 banner_text=vittec native fixture main.return=0 Source Subset native_ir_v1 is emitted only for the bootstrap-native subset: space &amp;lt;path&amp;gt; const NAME: string = &amp;quot;...&amp;quot; const NAME: int = 123 proc name() -&amp;gt; string { give &amp;quot;...&amp;quot; } proc name() -&amp;gt; string { give NAME } proc name() -&amp;gt; int { give 123 } proc name() -&amp;gt; int { give NAME } proc main(args: list[string]) -&amp;gt; int { give &amp;lt;integer&amp;gt; } proc main(args: list[string]) -&amp;gt; int { give NAME } use &amp;lt;path&amp;gt; / share &amp;lt;path&amp;gt; / import &amp;lt;path&amp;gt; at top level when const BOOTSTRAP_FULL_COMPILER: int = 1 is present proc main(args: list[string]) -&amp;gt; int { ... } with local let , direct call expressions, and if control flow when BOOTSTRAP_FULL_COMPILER: int = 1 is present export * Only version_text() and banner_text() are currently materialized as compiler identity procedures. Other string procedures are rejected until the native bootstrap surface grows intentionally. Integer procedures are accepted and emitted as proc.int.* records to pin the lowering shape, but they are record-only in v1. They are not callable from the generated shell compiler and do not affect process behavior unless their value is used through main.return . When BOOTSTRAP_FULL_COMPILER is enabled, the richer main body is accepted as source coverage for the real compiler entry point, but v1 still lowers it to the same shell contract and keeps main.return=0 . Non-Goals v1 The v1 subset intentionally does not support: string escapes or embedded double quotes, multi-line declarations or multi-line procedure signatures, bool , list, map, user-defined, or composit",

Documentation Source Sitemap Source Markdown Reading mode This page is the static HTML reader for bootstrap_seed.md . Internal Markdown links are rewritten to HTML when a matching reading page exists. Bootstrap Seed Contract The bootstrap seed is the trusted stage0 entry point for rebuilding the Vitte toolchain without repo-hosted host-language sources. Files Canonical readable source: toolchain/seed/src/main.vit Audited executable artifact: toolchain/seed/vittec0.seed Pinning manifest: toolchain/seed/manifest.txt toolchain/seed/manifest.txt records the seed source path, artifact path, artifact SHA-256, and expected --version output. make seed-verify checks the manifest hash against the artifact and validates the version string. The readable source is the canonical intent for review. The executable artifact is the stage0 trust root actually run by bootstrap scripts. make seed-verify keeps the two tied at the identity boundary by checking that source VERSION_TEXT , manifest version=... , and vittec0.seed --version match. Change Rule Any intentional seed rotation must update these contracts together: toolchain/seed/src/main.vit when the readable seed behavior changes. toolchain/seed/vittec0.seed when the executable seed artifact changes. toolchain/seed/manifest.txt when the artifact bytes or version change. tests/bootstrap_native/* snapshots when generated native output changes. CI must pass, including make seed-verify and make bootstrap-native-snapshots . The seed artifact must not change on its own. A change to toolchain/seed/vittec0.seed without a matching toolchain/seed/manifest.txt change is treated as seed drift and fails make seed-contract-check . Rotation Checklist Modify toolchain/seed/src/main.vit . Regenerate or edit toolchain/seed/vittec0.seed . Run make seed-rotation-report to inspect the current artifact hash and version. Run make seed-manifest-update to rewrite toolchain/seed/manifest.txt from the audited artifact and source VERSION_TEXT . Run make bootstrap-native-snapshots . Run make bootstrap-verify . Run make seed-contract-check . Local Checks make seed-verify make seed-rotation-report make posix-seed-shell-check make bootstrap-native-snapshots make seed-contract-check make bootstrap-native-drift-check make bootstrap-posix-smoke make build also runs bootstrap integration gates before the final source audit: compiler-real-native-gate compiler-test-suite-check-gate compiler-test-suite-bridge-gate driver-native-json-surface-gate These are complementary to make bootstrap-native-snapshots . The snapshot suite locks seed output and diagnostics; the integration gates verify that the current driver still exposes the expected native JSON envelopes, that the compiler entry builds without a bridge sidecar, and that the compiler test suite bridge remains scoped to compiler test sources. Local Parallelism CI jobs run in isolated workspaces, so their bootstrap artifacts do not collide. In one local worktree, bootstrap targets that install the seed are not parallel-safe because they rewrite shared bin/vittec0 . The single-workspace runner rule is: make bootstrap-native-snapshots installs the seed and mutates bin/vittec0 . make bootstrap-verify reinstalls and verifies bin/vittec0 . make bootstrap-posix-smoke depends on bootstrap-all , so it also rebuilds the seed artifact before running POSIX checks. make bootstrap-native-contract composes those flows and should be treated as an exclusive bootstrap runner in a local worktree. tools/bootstrap_native_snapshots.sh and tools/bootstrap_posix_smoke.sh use per-run temporary directories under target/ and clean them on exit, but the shared bin/vittec* artifacts are intentionally not isolated. Avoid running bootstrap targets concurrently in the same worktree. Source Coverage The readable seed and real compiler entry should exercise the current bootstrap-native forms they rely on: toolchain/seed/src/main.vit must include named string constants, named int constants, proc main(args: list[string]) -&amp;gt; int , and a named constant return. src/vitte/compiler/main.vit must include named VERSION_TEXT and BANNER_TEXT string constants, use a named string constant in version_text() , and define main . This is checked by make bootstrap-source-coverage-check and is included in the bootstrap-native contract targets. The stricter trust-root syntax contract is documented in docs/compiler/selfhost_core_subset.md and enforced by make selfhost-subset-check . Project Path Resolution Bootstrap and driver flows now accept a project directory as the CLI input path. When a command such as ./bin/vitte check . or ./bin/vitte build . -o target/app receives a directory-like path, it resolves the entry in this order: sr",

Welcome Documentation Visual Preview Sitemap Download Source Community News Diagnostics Suggestions @goginx community note: Vitte community work is organized around measurable compiler progress: every visible claim should point to a gate, a regression test, a diagnostic snapshot, or a generated report. Contributors are encouraged to discuss features in terms of contracts that can fail in CI, especially around frontend coverage, ownership, compile-time simulation, backend artifacts, and documentation accuracy. This keeps feedback practical: a proposal should say what behavior is expected, how it is verified, and which user-facing diagnostic or report proves the result. Code of Conduct Be precise, respectful, and technical in review and issue threads. Critique code and assumptions, never people. Attach reproducible evidence when reporting regressions. How to Contribute Open an issue with context, expected behavior, and impact. Propose a minimal patch linked to tests or docs evidence. Run documentation and compiler gates before asking for review. Public Roadmap Documentation priorities (compiler surface + stdlib coverage). Release timeline (patches, milestones, adoption updates). Implementation tracks (driver, grammar, diagnostics, backend). Example community flow # Example contribution path 1. Read the docs on the feature in doc.html 2. Inspect the source in source.html 3. Check diagnostics if you reproduce a failure 4. Share a minimal issue and patch in community This page is a hub for signals, not a replacement for the feature docs or implementation details.

Arbitration when architecture, ABI, or stdlib contracts conflict. Approval of breaking changes impacting compiler/stdlib public surface. How to escalate to @owner Use a concise issue summary: context, risk, proposed action, expected impact. Attach concrete artifacts (logs, reports, matrix links, reproduction path). Mark severity explicitly: critical , major , or minor . Owner-first contribution contract No checklist item is marked complete without repository evidence. Automation gates are preferred over manual status updates. Runtime and ABI claims must be backed by target-specific fixtures/reports. @roussov on the latest compiler modifications @roussov wrote this long-form community note to explain the latest compiler modifications in plain architectural terms. If you only want the short release summary, see News . If you want the full implementation story, this note is the right place to start.

Welcome Documentation Visual Preview Sitemap Download Source Community News Diagnostics Suggestions Source of truth The active diagnostics surface is the Vitte compiler itself. For implementation details, start from src/vitte/compiler/diagnostics/diagnostic.vit and the technical note docs/compiler/diagnostics.md . The bootstrap seed diagnostics described in docs/seed_diagnostics.md are a narrower stage0 contract, not the full compiler surface. Official sequence vitte check &lt;file&gt; vitte check &lt;file&gt; --diagnostics-json vitte run &lt;file&gt; vitte parse &lt;file&gt; vitte explain &lt;code&gt; vitte dump-ast &lt;file&gt; vitte dump-hir &lt;file&gt; vitte dump-mir &lt;file&gt; Use tests/strict_ok.vit as the tracked smoke fixture when a docs page needs a small known-good source file. Stable JSON surface schema = \"vitte.compiler.surface\" surface = \"diagnostics\" valid tells whether the request succeeded pipeline_failed_at identifies the first failing stage primary_report.diagnostics[] contains the flattened report phase_reports.* keeps per-phase diagnostics Phase map frontend : lexer , parser , ast_validation resolution : module_resolution , symbol_resolution , sema middle-end : hir , typeck , borrowck , mir , mir_lowering , mir_verification , ir backend : backend , linker , runtime_execution driver : CLI/input/configuration failures before or around the pipeline Frequent codes PARSE_E_UNCLOSED_BLOCK - parser reached EOF before a closing delimiter E1005 - unknown identifier TYPECK_E_ASSIGN_MISMATCH - assignment type mismatch BORROWCK_E_USE_AFTER_MOVE - moved value used later LIMIT_FILE_SIZE_MAX - source exceeds hard input-size policy What to do first Read the first failing phase and code, not the whole waterfall. Reduce the repro to the smallest file that still fails. Re-run with --diagnostics-json when you need machine-readable detail. Use AST/HIR/MIR JSON dumps only after the frontend phase is clean enough to progress. Quick index parse : malformed syntax, recovery diagnostics, unclosed delimiters. resolve : missing modules, symbols, visibility and name binding issues. typeck : incompatible assignments, call arity/type mismatches, non-exhaustive matches. borrowck : use-after-move, borrow conflicts, lifetime failures. driver : invalid CLI input, path/policy issues, hardening limits. Example space sample proc main() -> void { let x = 1 give x + \"bad\" } This minimal example is useful for understanding diagnostics: the compiler can parse the code, but it will fail later with a type mismatch because int + string is invalid. Reduce the repro to this smallest form when you triage a failure. Practical reading Diagnostics should be read as a contract, not as a wall of text. The phase tells you where the pipeline stopped, the code names the stable failure class, and the JSON envelope lets you inspect the same event without scraping text output. For a fast triage, use this order: Identify pipeline_failed_at or the first human-visible phase. Read the primary code, message, label, note, and help. Reduce the repro to the smallest snippet that still fails. Re-run with --diagnostics-json if you need exact fields or per-phase separation. Only then move to AST/HIR/MIR dumps if the failing phase is past parsing. That sequence keeps bug reports useful: the report should name the phase, the code, the smallest repro, and the expected behavior instead of only describing the symptom. If you need a broader starting point, read Documentation for the compiler surface and Source for the implementation path. ← Previous Next → diagnostics.html Back to home · Public status",

Compatibility matrix Consumer Status Notes Users Stable Patch and release notes available Contributors Stable Roadmap and evidence links available CI/Automation Stable Docs gates integrated in workflows Fast Technical Feed @goginx update: focus shifted to measurable compiler health and local-change incremental recompilation guarantees, with new metrics/health surfaces and stronger recovery + LSP stability contracts. Delivery gates: seed command surface now includes `release`, `package`, `workspace`, `compat-check`, `migrate`, `stress`, and `ci-gate --strict` with report outputs under `build/reports`. Self-host: seed-to-generation consistency checks now produce deterministic audit reports under target/selfhost_completion/ . Release engineering: release archive generation + SHA256 verification flow is now available from compiler CLI (`release build|verify`). Runtime ABI: panic boundary primitives are now explicitly declared and implemented for native runtime integration. Link step: runtime C payload auto-wiring is now part of linker artifact generation path. Targets: compiler target normalization accepts a wider matrix of modern and legacy aliases for old-machine compatibility flows. Compiler strictness: entry lock + diagnostics migration gate + reachability audit are now part of strict compiler quality flow. Docs pipeline: single chain build_docs_site → build_grammar_extras → sync_ebnf_memory_pages → build_static_extras → checks . Policy: EN-only output, canonical/hreflang stabilized, vitte-lang.org normalized. Search: weighted ranking (title x3, path x2, content x1), filters, keyboard nav, URL state persistence. Quality gates: broken links, duplicate script/css, html size, perf budget, docs doctor, pedagogy progressive gate. Offline: service worker + offline fallback page + critical assets cache.

Pipeline Compiler Model Parse AST to IR Visual Preview Railroad SVG Sitemap Compiler Vitte The source view reads the project through the Vitte compiler stack: driver surface, grammar surface, snapshots, and repo checks are aligned around the same code paths. Driver alignment Review the driver alignment notes. Compiler flow See the pipeline from parser to backend. Visual assets Preview the README hero, compact mobile asset, and social card. Source guides Open the HTML reader pages for source-backed docs. Understanding the compiler The Vitte compiler reads as a series of simple layers: parser, resolution, IR, then backend, with the driver and linting surface expressed in the same language as the rest of the repository. Parser : reads the code and builds the AST. Resolution : connects names, imports and symbols. IR : lowers to an intermediate representation. Backend : produces the target code. Example read path # Read the parser entry point open src/vitte/compiler/frontend/parse/parser.vit # Read the HIR/MIR lowering path open src/vitte/compiler/middle/lower/mod.vit # Inspect the bootstrap contracts in docs open docs/bootstrap_seed.html This example shows how to follow the source path from parser, through lowering, to bootstrap and documentation contracts.

Welcome Documentation Visual Preview Download Source Community News Diagnostics Suggestions Read Open documentation Test Install the tools Debug Open diagnostics Contribute Read source Release See the Markdown migration note Example # Start with a single action make quickstart-check # Then narrow to a failing diagnostic or a documentation update Use this pattern to keep changes small and reviewable: one main action before branching to a deeper follow-up. Simple rule: only one main action per block, then we refine only if the context requires it. How to choose When the project feels busy, pick the smallest block that moves the work forward. If you need to understand a feature, start with Documentation . If you need to prove the behavior, go to Diagnostics . If you need the current implementation, open Source . If you need the latest project context, read News . The suggestion page exists to keep the next action obvious. The general order is stable: Read the page that describes the rule. Check the implementation or the error path that enforces it. Run the smallest test that can confirm the behavior. Only then broaden the change to docs, examples, or release notes. Suggestion list Read : Open Documentation for the current feature or rule. Inspect : Open Source and follow the implementation path. Verify : Open Diagnostics and match the error message before fixing. Test : Use a focused command like make quickstart-check or a targeted test file. Document : Add an example or explanation to the HTML page when the behavior is not obvious. Release : Update News or migration notes only after the change is confirmed. This keeps the work easy to review and easy to explain. It also keeps the repository honest: every suggestion should point toward a concrete artifact, not just a vague intention. ← Previous suggestions.html Back to home · Public status",
