# Hime-san language server Hime-san `v1.0.0-beta.2` adds a reusable, read-only Language Server Protocol surface: ```sh himesan lsp --stdio ``` The server accepts one local workspace root per process. Editors with multiple workspace folders start one process for each folder. Standard output contains only framed JSON-RPC; bounded operational messages go to standard error and do not include template source, environment values, or secrets. ## Beta 2 capabilities - full-document synchronization and unsaved in-memory overlays; - live compiler diagnostics, trust warnings, duplicate components, and statically knowable component cycles; - UTF-16 protocol positions without changing compiler CLI byte coordinates; - hover help for tags, inferred output contexts, component signatures, and trusted-output boundaries; - document symbols for the declared component and template regions; - delimiter/tag completion plus same-package and already-imported component completion; and - component go-to-definition. The index honors the compiler's symlink, nested-module, VCS, vendor, and filesystem boundaries. Open/save is analyzed immediately; ordinary edits are debounced for 200 ms and superseded analyses are canceled. Appearance, deletion, rename, and save notifications rebuild the bounded source index. ## Deliberate exclusions The language server does not generate files, report generated-file freshness, invoke Go or `gopls`, execute project code, fetch dependencies, access the network, or start `himesan dev`. It provides no general Go or HTML completion, formatting, rename, references, automatic imports, or live browser preview. Use explicit `himesan check --json` for committed-output freshness and normal Go tests/builds for type checking. Editors remain responsible for workspace trust, process startup, and user-visible command policy. ## Resource limits Protocol frames and individual documents are limited to 16 MiB, the indexed workspace source set to 64 MiB and 10,000 `.sando` files. These are denial-of- service guardrails for trusted local workspaces, not a sandbox for hostile template authors.
