A build with an empty cache type-checked scriptc's own declaration files,
the TypeScript libraries and scriptc's declarations, before reusing the
answer in later builds. That check was 18 ms of a 105 ms first build of
hello world.
- build-native-cli.mts has the built compiler build a module without
imports and a module with a type error, each in an empty cache, and
records the content keys of the declaration file sets the checker
reported no diagnostics in: the checker release, the compiler options,
and each file's name and sha256. They ship in
lib/declarations/lib-diagnostics.json, named by the toolchain manifest's
lib_diagnostics.
- A build whose cache has no answer computes the files' content key and,
when the shipped answers hold it, uses no diagnostics for those files
and stores that answer in the cache. The shipped answers apply only
while the checker is the distribution's own tsc-ts and its package
version is the release they were recorded with; a changed file has
another key.
- A compiler the build host cannot run ships without them.
tsc-ts 0.0.8's API server serves on the named pipe the Node host
connects over on Windows (tsc-ts --api --pipe), and the native compiler
already starts it over its standard streams there, so tsc-ts is the
default checker on every platform. SCRIPTC_CHECKER=tsgo still selects
tsgo.
The compiler depends on tsc-ts 0.0.8, which the release-age exclusions
admit with its platform packages and @scriptc/threads 0.4.2.
The Windows CLI smoke test runs with both checkers, and
verify-native-cli.mjs --run checks that a distribution's tsc-ts runs on
its platform (tsc-ts.exe on Windows).
scriptc's frontend talks to a TypeScript 7 API server. tsc-ts serves the
same API as tsgo, and it is now the default checker; SCRIPTC_CHECKER=tsgo
selects tsgo, which scriptc still includes.
- @scriptc/compiler depends on tsc-ts 0.0.3. The native distribution
ships its platform package as lib/tsc-ts, named by a new tsc_ts field
of the toolchain manifest; a manifest without it takes the executable
of an installed tsc-ts package.
- The executable cache key includes the tsc-ts executable's identity, in
the compiler and in the CLI's startup route.
- tsc-ts keeps the syntax trees it builds for the life of its process,
so the source parser starts a new server after 256 KB of parsed
source instead of letting one server grow with every file.
- A CI job compiles every corpus program with both checkers, in release
and dev, and requires the same LLVM IR and diagnostics
(scripts/checker-identity.mjs).
- Tests that compare with the TypeScript 7 SDK, the checker-panic
diagnostics, and the protocol tests run against tsgo.
- Enforce oxlint and oxfmt for owned JavaScript and TypeScript with independent CI checks.
- Preserve compiler import boundaries and protected fixtures while cleaning up lint findings.
- Standardize source formatting and validate import, fixture, and embedded-source protections.
* Make native installs portable and smaller
- Support glibc 2.34 with portable compiler binaries and static LLVM helpers.
- Bundle the host runtime and discover optional cross-target packs from project dependencies.
- Add application build benchmarks covering latency, executable size, and memory.
* Keep bootstrap tools available in Sandbox validation
- Isolate Zig for native compiler bootstrap and glibc entropy contracts.
- Preserve the existing toolchain scope for cache and corpus tests.
* Fix portable compiler bootstrap linking
- Keep native support objects compatible with the destination host linker.
- Resolve installed targets using the host declared by the toolchain manifest.
- Resolve Windows toolchain paths during package verification and archive creation.
- Preserve completed native builds and accepted uploads across release tooling fixes.
* feat: ship the self-hosted native scriptc CLI
- Run the shared compiler and CLI natively, including library builds and compile-time evaluation.
- Install native platform packages and ship relocatable standalone distributions.
- Preserve program semantics and reuse validated build artifacts for fast rebuilds.
* fix: complete native CLI integration and validation
- Preserve library diagnostics and run recursive compiler work on the main stack.
- Restore packaged helper permissions and exercise native npm and Wasm library builds.
- Recover interrupted Sandbox status probes within the original command deadline.
