From cb4bfae5e73cf24375dccc03ce331b8176de90ee Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Gabriel=20Fr=C3=B3es=20Franco?= Date: Mon, 11 May 2026 16:27:39 +0000 Subject: [PATCH] phase 13: workspace/rename + executeCommand router + nuwiki.file.delete Server-side rename with cross-document link rewriting (P11's read_or_open delivers on its promise) and the first executeCommand entry. Plus the routing infrastructure that Phases 14-17 will hang their own commands off of. commands.rs: - commands::execute(backend, name, args) dispatches by command name and returns the WorkspaceEdit to apply. - COMMANDS const slice is the source of truth for what's advertised in ExecuteCommandOptions.commands. - First entry: nuwiki.file.delete with args { uri: } returning a WorkspaceEdit with a DeleteFile op. rename.rs: - compute_rename(backend, target_uri, new_name, utf8): 1. Resolve the wiki via wiki_for_uri. 2. Build new URI from wiki.root + new_name + extension. 3. Snapshot the index's backlinks for the old page name before releasing the read lock so we don't hold it across awaits. 4. For each backlink, read_or_open the source (live state or disk + reparse) and validate the cached span against current text. 5. Rewrite the [[...]] segment with rewrite_wikilink_target, preserving anchor and description. 6. Add the RenameFile op so the builder emits it before the text edits in documentChanges ordering. - build_new_uri handles subdirectory paths and avoids double- appending the file extension. - rewrite_wikilink_target is pub so other tooling can call it. lib.rs: - Capabilities: rename_provider + execute_command_provider listing commands::COMMANDS. - New rename handler: cursor-on-wikilink renames the linked page, else the buffer's file. Delegates to rename::compute_rename. - New execute_command handler dispatches via commands::execute, then pushes the resulting WorkspaceEdit through client.apply_edit. On unknown command or bad args, logs and returns null. - read_or_open loses its allow(dead_code) attribute now that Phase 13 calls it. - rename_target_uri helper shares index-resolution with goto_def. Tests (11 new in phase13_rename_commands.rs): - rewrite_wikilink_target: plain, with description, with anchor, with both, subdirectory path, non-wikilink-text rejection. - build_new_uri: under root, with subdirectory, extension dedup, empty path segments skipped. - nuwiki.file.delete builder smoke test (DocumentChanges + DeleteFile). All 211 v1.0+Phase 11+12 tests still pass.
