## 项目历史与用法

Harlequin is a terminal SQL IDE created by Ted Conbeer to bring editor-style database work into a TUI. It began in 2023 as a Python/Textual application centered on DuckDB, then grew into a plugin-oriented database client with adapters for SQLite, PostgreSQL, MySQL/MariaDB, ODBC, BigQuery, Trino, Databricks, ADBC, and other back ends.

### 项目历史

The public repository started in May 2023 with early commits for a working CLI, schema sidebar, query editor, and data viewer. The 0.0.x changelog shows a fast iteration cycle: query execution became asynchronous, SQL files could be opened and saved from the editor, DuckDB extension support landed, multiple editor buffers and multiple result tabs appeared, and database-file workflows gained read-only and export features.

Version 1.0.0, tagged in September 2023, marked the point where the core terminal database-client experience had settled enough for a named milestone. Subsequent development broadened Harlequin from a DuckDB-first SQL TUI into a general database client: the official docs describe adapter plug-ins as the generic interface to databases and list core and community adapters beyond the built-in DuckDB and SQLite support.

### 采用历史

Harlequin's adoption path follows the DuckDB and terminal-UI communities: it is installable with Python tooling, documented as having a Homebrew formula, and packaged in Homebrew and Nix in the supplied package-manager facts. Its README also notes that the Homebrew formula bundles several adapter packages, which made the formula attractive for users who wanted a single terminal SQL client with more than DuckDB support.

The project attracted package-manager attention because it sits at the intersection of several popular command-line trends: local analytical databases, terminal user interfaces, Python application packaging, and pluggable database adapters.

### 使用方式

Harlequin is run as a command-line application, commonly with no arguments for an in-memory DuckDB session or with database paths/connection strings for concrete databases. Users can pass adapter options from the shell, keep profiles in TOML config files, edit and execute SQL in a terminal editor, browse catalogs, and export result data.

The adapter model is central to everyday use. The official adapter docs describe DuckDB as the default, SQLite as built in, and additional adapters as Python packages discovered at runtime, so package installs often matter as much as the core executable.

### 为什么软件包爱好者会关心

Harlequin is interesting to package nerds because it packages a rich, stateful terminal application rather than a small single-purpose CLI. Formula maintainers have to care about Python runtime behavior, optional adapters, database client dependencies, and config discovery.

It also illustrates a newer class of Homebrew formula: a Python TUI that competes with native database CLIs by bundling editor, catalog, and result-viewer behavior into one command while still remaining scriptable enough to live in terminal workflows.
