VSCode LSL

VSCode LSL provides editor support for Second Life's Linden Scripting Language (LSL).

Features

• LSL syntax highlighting, language configuration, and bracket/comment support.
• 59 extension-maintained snippets, including states, events, flow control, listeners, dataserver, and SLURL helpers.
• Hover documentation with signatures, normalized Markdown-compatible descriptions, and an official Wiki reference when a suitable page exists.
• Completion for the generated core LSL catalog, classified as functions, constants, events, types, and keywords.

Compatibility

VSCode LSL supports VS Code ^1.90.0. Extension-host tests pass on VS Code 1.90.0 and the current stable test host (1.128.0 during the 1.0.0 release validation).

Language data

The extension contains 1,284 core LSL symbols: 742 constants, 482 functions, 43 events, 8 types, and 9 keywords. It is generated from Second Life Viewer develop commit fa38b81a620e69af7fe6dfee47dcd1a5253ce1d7, with a reviewed Second Life Wiki reconciliation overlay. The source snapshot was refreshed on 2026-07-12.

The original extension used the 2017 KWDB database and the Makopo converter. This historical data is retained as attribution only; it is not the source of the current generated runtime catalog.

Known limitations

• The generated catalog covers core Second Life LSL only.
