patchloom: v0.6.0

Patchloom for VS Code 0.6.0

This release adds Quick Actions for multi-match document edits and applying a patch file. It also fixes Native MCP registration and Configure MCP so the CLI shows up in VS Code and Cursor without wiping existing config.

Highlights

Three new Quick Actions cover updating or deleting matching JSON, YAML, or TOML nodes, and applying a unified diff, Codex Begin Patch, or Aider SEARCH/REPLACE. Native MCP now registers in VS Code 1.100+ and runs in the open workspace folder. Configure MCP keeps JSONC comments and writes Cursor's mcpServers key.

Minimum supported CLI remains 0.3.0. Recommended CLI is still 0.31.0. No settings migration is required.

New features

• Update matching structured values. Quick Action runs patchloom doc update (CLI 0.27+) to change every JSON, YAML, or TOML node that matches a wildcard or predicate, with the same preview-then-apply flow as other document edits (#246).
• Delete matching array items. Quick Action runs patchloom doc delete-where (CLI 0.27+) with an array path plus a key=value predicate. A miss is treated as a hard failure, not a silent no-op (#246).
• Apply patch (unified / Begin Patch / SEARCH-REPLACE). Quick Action runs patchloom patch apply (CLI 0.30+) on a unified diff, Codex *** Begin Patch, or Aider SEARCH/REPLACE file. Merge patch remains the three-way path for stale unified diffs (#246).

Bug fixes

• Native MCP never appeared in VS Code 1.100+. The provider called a method name that does not exist, so registration did nothing. It now registers a stdio server with the resolved CLI path and only PATCHLOOM_* environment keys (#249, #250).
• Native MCP tools resolved relative paths from your home directory. The server working directory is now the first workspace folder (#251).
• Configure MCP wiped comments and sibling servers in JSONC. A parse failure used to become an empty object and then a rewrite. Invalid files are refused; valid JSONC keeps comments and other servers (#248).
• Cursor wrote VS Code's servers key. .cursor/mcp.json now uses mcpServers. A Cursor file that only has servers is no longer treated as already configured (#252, #253).
• A broken patchloom.path kept offering Install. When the setting points at a missing or outdated binary, the status action is Open Settings, not a managed Install or Update (#249).
• Update Patchloom compared the latest release to the active PATH or settings binary. Managed Update now compares GitHub latest to the binary in extension storage (#244).
• A path or value of --apply or --contain dropped workspace sandboxing or turned a confirmed apply into a dry run. Those tokens stay operands. Files named --apply and option values such as -n are passed so the CLI does not treat them as flags (#254, #256, #257).
• A workspace symlink to an outside patch escaped --contain. Apply now follows the real path and stages an outside target under .patchloom-* so the write sandbox stays on (#247).
• Search failures stayed in a toast. Errors now also write the CLI text to the Patchloom output channel (#244).

Recommended CLI	0.31.0 (minimum still 0.3.0)	0.31.0 (minimum still 0.3.0)
Unit tests	373 passed, 6 skipped	431 passed, 7 skipped

Upgrading

1. Update the extension to 0.6.0 (VS Code Marketplace, Open VSX, or .vsix from the GitHub Release).
2. Update the Patchloom CLI using the channel that matches how the extension resolved it (see Patchloom: Show Status → Source):

# Managed install (extension storage): command palette
# Patchloom: Update Patchloom

# PATH via Scoop (preferred Windows PATH channel)
scoop update patchloom

# PATH via Homebrew
brew upgrade patchloom

# npm / cargo / shell installer: see README Install section

3. Confirm with Patchloom: Show Status that the detected CLI is 0.31.0 or newer (0.3.0+ still runs; 0.31.0 is recommended). The new Quick Actions need CLI 0.27.0+ for doc update / doc delete-where and 0.30.0+ for patch apply.
4. Optional: run Configure MCP if you use Cursor or a commented .vscode/mcp.json, then Update matching structured values or Apply patch (unified / Begin Patch / SEARCH-REPLACE) from the Quick Action picker.

Install

• VS Code Marketplace
• Open VSX
• GitHub Release assets: patchloom.vsix and build provenance (patchloom.vsix.intoto.jsonl)
