Connection String Import, Visual Query Builder Fix, and More: v0.9.8

v0.9.8 is a focused release that brings a highly requested quality-of-life feature — paste a connection URL and have the form filled in for you — along with two important Windows compatibility fixes and new plugin capability flags for connection string support.

Connection String Import

Network-based drivers (PostgreSQL, MySQL, and compatible plugins) now show a "Import from connection string" section in the new connection modal. Paste a URL like:

postgres://alice:secret@db.example.com:5432/myapp
mysql://root@127.0.0.1:3306/dev

and Tabularis parses it instantly — host, port, username, password, and database name are all populated into the form. You can then tweak individual fields before saving.

The parser is fully tested and handles edge cases: URL-encoded credentials, missing ports (falling back to the driver's default), and optional database segments.

Plugin support for connection string import

Plugins can now declare whether they support connection string import via two new optional capability flags in manifest.json:

Both flags also accept their camelCase equivalents (connectionString, connectionStringExample) for plugin compatibility.

Example for a ClickHouse plugin:

{
  "capabilities": {
    "schemas": true,
    "views": true,
    "routines": false,
    "file_based": false,
    "folder_based": false,
    "connection_string": true,
    "connection_string_example": "clickhouse://user:pass@localhost:9000/default",
    "identifier_quote": "\"",
    "alter_primary_key": false
  }
}

Bug Fixes

Visual Query Builder: Drag-and-Drop on Windows

The Visual Query Builder's table drag-and-drop was broken when running inside WebView2 (the browser engine used by Tauri on Windows). The HTML5 dragstart/drop API is not fully supported by WebView2, causing tables dragged from the sidebar to be silently ignored.

The fix replaces the HTML5 drag API with pointer events (pointerdown, pointermove, pointerup), which work consistently across all platforms including WebView2.

SQLite: SQLITE_CANTOPEN (Error Code 14) on Windows

Opening an SQLite database on Windows could fail with error code 14 (SQLITE_CANTOPEN) in certain path configurations. The root cause was constructing the connection URL by string-formatting the file path — on Windows, backslash-separated paths embedded in a sqlite:// URL are not valid.

The fix switches to SqliteConnectOptions::new().filename(&path) instead of parsing a URL string, which correctly handles Windows paths including those with spaces or backslashes.
