lsq is a CLI tool written in Go that serves as a lightning-fast companion for Logseq, the open-source knowledge base. Its core functionality is creating, appending to, and viewing daily journal entries directly from the terminal, following Logseq's file naming and formatting conventions (Markdown or Org-mode). The tool provides a rich set of flags for targeting specific dates, searching pages via a trie-based index (including alias support), regex searching across journals and pages, and piping content from STDIN. It also supports indentation for nested list items and a configuration file in EDN format for persistent settings. The architecture is a single-binary monolith with clear separation into config, system (file I/O, editor launch), trie, todo state cycling, and an EDN validator module. While the tool is tightly coupled to Logseq's directory structure (journals/ and pages/ folders), the underlying components like the trie search, file appending logic, and configuration loading are well-isolated and could be reused in other Go projects with minimal adaptation.
