infraguard lsp

Start the ROS Language Server Protocol (LSP) server for editor integration.

Synopsis​

infraguard lsp [flags]

Description​

The lsp command starts a Language Server Protocol (LSP) server that communicates via standard I/O (stdio). It provides intelligent editing support for ROS templates in editors like VS Code, including:

  • Auto-completion — Resource types, properties, intrinsic functions, Ref/GetAtt targets
  • Real-time diagnostics — Format version, resource types, required properties, type mismatches
  • Hover documentation — Descriptions, type info, constraints for resources and properties
  • Go to Definition — Jump to parameter and resource definitions from references

The LSP server supports both YAML and JSON template formats.

Flags​
