sigil-log

Structured logging for Sigil.

Provides configurable log levels, text and JSON output formats, per-module filtering, and lazy macros that skip evaluation when the level is inactive.

This package was extracted from the sigil monorepo — the in-tree history under packages/sigil-log/ is preserved here as master.

Usage

(log-info "Server started" port: 8080)

(log-error "Request failed" path: "/api" status: 500)

;; Switch output format, raise/lower level
