Module DevLog 

DevLog - Tag-filtered development logging for Grove

Controlled by LAND_DEV_LOG environment variable. The same tags work in both Mountain (Rust) and Wind/Sky (TypeScript).

Usage

LAND_DEV_LOG=grove,wasm ./Grove          # only grove + WASM
LAND_DEV_LOG=all ./Grove                 # everything
LAND_DEV_LOG=short ./Grove              # everything, compressed + deduped
LAND_DEV_LOG=transport,grpc ./Grove     # transport + gRPC
./Grove                                  # nothing

Short Mode

LAND_DEV_LOG=short enables all tags but compresses output:

• Long app-data paths aliased to $APP
• Consecutive duplicate messages counted ((x14) suffix)
• Rust log targets compressed (D::Binary::Main::Entry → Entry)

Tags (Grove-specific tags plus shared tags)

Tag	Scope
grove	Extension host lifecycle: create, start, kill, exit
wasm	WASM module loading, compilation, execution
transport	IPC/gRPC/WASM transport strategy and routing
grpc	gRPC/Vine: server, client, connections
extensions	Extension scanning, activation, management
lifecycle	Startup, shutdown, phases, window events
config	Configuration get/set, env paths, workbench config
ipc	IPC routing: invoke dispatch, channel calls
vfs	File stat, read, write, readdir, mkdir, delete, copy
storage	Storage get/set/delete, items, optimize
commands	Command registry: execute, getAll
exthost	Extension host: create, start, kill, exit info
model	Text model: open, close, get, updateContent
output	Output channels: create, append, show
bootstrap	Effect-TS bootstrap stages

Functions

AliasPath

Replace the long app-data path with $APP in a string.

AppDataPrefix

Get the app-data path prefix for aliasing (cached).

DetectAppDataPrefix 🔒

EmitOTLPSpan

Emit an OTLP span to the local collector (Jaeger at 127.0.0.1:4318). Fire-and-forget on a background thread. Stops trying after first failure.

EnabledTags 🔒

FlushDedup

Flush the dedup buffer - prints the pending count if > 1.

GetTraceId 🔒

IsEnabled

Check if a tag is enabled.

IsShort

Whether LAND_DEV_LOG=short is active.
