v0.1.29

Quick-fix actions, import completions, and faster saves.

Code actions — remove unused imports

textDocument/codeAction is now implemented. When forge-lint reports an unused-import diagnostic, the server offers a Remove unused import quick-fix that deletes the entire import directive in one step.

In Neovim this shows up via vim.lsp.buf.code_action(). No configuration needed — it works automatically when lint is enabled.

Import path completions

Typing inside an import string now triggers path completions:

import "./  // ← completion list shows files in the directory
import "@openzeppelin/  // ← completion list shows package contents

Completions resolve against forge remappings and the project root so remapped paths (e.g. @uniswap/v4-core/) resolve correctly.

Find all references — working for declarations

textDocument/references was returning null for most cursor positions. It now returns results for state variables, functions, events, errors, and other declarations:

• owner state variable in Shop.sol → 11 references
• PoolNotInitialized error in PoolManager.t.sol → 67 references

Faster saves on large projects

Two changes make saves noticeably faster on large codebases like v4-core:

Redundant rebuild skip. On every didSave the server now hashes the incoming file content and compares it against the last compiled build. If the content is identical — which happens on format-on-save loops where the formatter returns edits, Neovim applies them, and the file is saved again already-formatted — the full solc recompilation is skipped entirely. Repeat saves go from ~5s to instant.

Non-blocking pragma crawl. Before compiling, the server walks the full transitive import graph to find the tightest solc pragma constraint. On PoolManager.t.sol that is ~95 files read synchronously. This crawl was running on the tokio async thread, blocking all other LSP requests (hover, completion, definition) until it finished. It now runs on the blocking thread pool via spawn_blocking.

workspace/executeCommand

Two commands are available:

• solidity.clearCache — deletes the on-disk cache and wipes in-memory AST, forcing a clean rebuild on next save.
• solidity.reindex — evicts in-memory AST and triggers a fast background reindex from the warm disk cache without deleting it.

Trigger from Neovim with:

vim.lsp.buf.execute_command({ command = "solidity.reindex" })

Non-blocking didSave

Rapid saves (:w spam) no longer stack. Each URI has a dedicated watch channel — new saves collapse into the running worker instead of queuing separate builds. Only the latest content is compiled.
