Scarp alpha.6: navigate symbols and measure vector RMS

v0.0.6-alpha.1 was published on 5 November 2026. It extends the earlier project-aware Scarp CLI with read-only, cross-file source symbol and reference inspection, plus a finite vector rms builtin. The language remains experimental and the website does not claim an integrated language server, automatic refactoring, or stable APIs.

Inspect declarations and references

Use an alpha.6.1 interpreter (or a compatible newer release) with a Scarp source file or explicit project directory. These commands statically resolve the program without running ordinary statements:

scarp inspect symbols --json hello.srp
scarp inspect references --json hello.srp

Both JSON outputs identify schema version 1 and their respectivekind values. They retain source locations for supported declarations and reference sites, including cross-file uses and shadowed names. Symbol IDs are compilation-local; consumers must rebuild indexes after edits rather than persisting IDs.

Read the source-pinned symbol-index contract for JSON fields, failure modes, size limits and what is deliberately excluded. This is not an LSP server or a rename operation.

RMS for finite numerical vectors

The rms(vector) builtin computes a scaled, compensated root mean square for a nonempty finite vector. It is intended to avoid intermediate overflow when input values are large. An empty input produces a diagnostic. The following example is executed in website CI under the published alpha.6 source—not under the historical alpha.1 baseline:

print(rms([2.0, -2.0]));

2.0

See the pinned RMS reference and verified example scope. This feature does not introduce general tensors, GPU computation, automatic differentiation or a model-training framework.

What remains experimental?

exec, static verify, offline project creation and inspection retain their established CLI meanings. The earlier limited C11 emitter remains a Rust embedding API, not a scarp compile command. No general native executable generator or package registry is included.

The GitHub release record and annotated-tag source commit establish publication and source identity. The compiler's source-pinned design notes still contain candidate-stage wording; publication status here is based on the actual GitHub release.
