GOPLS TIGHTENS PROTOCOL TYPES AS EXP ADDS TRAJECTORY UTILITIES

By RepoJournal · Filed · About Go

gopls just locked down its LSP protocol with stronger enum typing, while the experimental track opens a new eval/trajectory module for advanced analysis workflows.

gopls/internal/protocol shipped a string enum type for field kinds [1], closing out a spec review comment and aligning with vscode-go's parallel work. This is the kind of incremental protocol hardening that prevents subtle marshaling bugs down the road. Meanwhile, golang/exp landed the ATIF utility module [2] under eval/trajectory, setting up infrastructure for trajectory-based evaluation and analysis. The two moves sit on different vectors but both signal deliberate foundation-building: gopls is tightening its contract with IDEs, while exp is establishing patterns for the next generation of analysis tooling. Neither breaks existing code, but both matter if you're shipping LSP extensions or building analysis layers on top of Go.
