Each @scriptc/cli-<platform> package bundled its platform's LLVM helper
and runtime pack, which are also published as @scriptc/llvm-<platform> and
@scriptc/runtime-<platform>. The CLI packages now depend on those packages
at the same version (workspace:*, which pnpm pack writes as the exact
version) and leave them out: cli-linux-x64-gnu goes from 115 MB to 60 MB
packed.
- build-native-cli.mts --platform-packages, which each CLI package's
build:native passes, writes a manifest without llvm_package, runtime_pack
and runtime_packs.
- loadNativeToolchain resolves a missing helper or host runtime pack as
Node resolves the package from the compiler's directory: nested in the
platform package, beside it (hoisted, or pnpm's virtual store) or higher
up. It requires the compiler's version, and an absent or mismatched
package fails with an error that names it.
- installNativeCli records where the package manager put both packages in
the installed manifest, with the same checks.
- verify-native-cli.mjs requires the exact dependencies of a platform
package and checks the resolved packages' versions.
- package-native-cli.mjs bundles the helper and runtime pack into the
standalone archives, which stay self-contained.
- smoke-native-install.mjs installs the helper and runtime pack tarballs
with the platform package; the bootstrap's exported package drops its
bundled copies first.
- release.yml publishes the CLI packages only once every helper and
runtime pack package resolves on npm, and scriptc only once the CLI
packages resolve, each wait at most 25 minutes. A rerun skips the
uploads npm already accepted and waits again.
The native sanitizer build chose the variants to compile by artifact path.
Since the runtime pack stores identical objects once, two variants of a
unit can share a path, so it compiled such a unit for both variants and
linked it twice (duplicate symbols in the sanitized native bootstrap).
selectedRuntimeUnits now returns each selected unit with its variant;
selectRuntimePackArtifacts and the sanitizer both use it.
Staging the native CLI's assets ran llvm-strip unconditionally and failed
on hosts without it. Without llvm-strip on PATH, tsc-ts now keeps its
symbols and the build prints a warning; the release hosts install LLVM.
Runtime packs: variants of a unit that do not read their defines, and
flavors that compile a unit the same way, produce identical objects and
bitcode. The pack build now points those manifest entries at one file
(shareIdenticalArtifacts) and deletes the copies. Each link selects one
flavor and one variant per unit, so no link names a shared file twice. The
linux-x64-gnu pack keeps 1,191 of its 1,448 artifact files.
Native CLI packages:
- The comptime evaluator builds with -g0 and the executable strip flags,
and the Windows build no longer ships its .pdb.
- The copied tsc-ts executable is stripped with llvm-strip, which rewrites
the linker-signed code signature of Mach-O executables.
- On arm64 macOS, verify-native-cli.mjs --run checks the code signatures
of the compiler, tsc-ts and the comptime evaluator.
- SCRIPTC_NATIVE_KEEP_SYMBOLS=1 keeps the symbols of all three.
- The copied runtime sources and declarations get LF line endings. A
Windows checkout converts them to CRLF, so the Windows CLI shipped files
that differed from @scriptc/runtime's.
Without @types/node, every program loaded scriptc-node-fallback.d.ts whole:
the console and process globals and 47 Node modules, about 8,100 lines,
parsed, bound and checked in every cold build whether or not the program
imported them.
- The fallback file keeps the globals and the modules they name (console,
readline, readline/promises, perf_hooks, tty). Every other module, under
both spellings, has its own file in ambient/node-fallback/, which
references the files of the modules its declarations name.
- A module's file joins the program when one of the program's files names
the module in a string literal: imports, requires, import types and JSDoc
types all name modules that way. The entry is read before the first
program; the program-root discovery passes add modules that other files
name. Files are read as tsgo reads them, and the TypeScript libraries and
scriptc's own declarations are skipped.
- The checks that recognized the fallback file by its path recognize every
fallback file.
package-shims.ts registers implementation modules shipped with the
compiler per package and major version (chosen by the importer's
installed version) and reads the project's never-loaded packages from
"scriptc": { "packages": { "<name>": "unloaded" } }. Module edges go
through resolveProjectImport; the npm resolution, the npm-edge walk and
the --npm-static set skip such packages; the tsgo host reads a shimmed
package's index.d.ts as a re-export of its implementation; an unloaded
package's require() throws Node's not-installed MODULE_NOT_FOUND.

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.
* 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.
