Problem

A positioned file link opened in a JetBrains IDE was launched as idea --line N --column C <file>, with no project. The IDE then attaches the file to whichever window is open. With checkout A of a repo open and a thread working in checkout B, the file from B opens inside A's window as a file outside that project. #5885 also reports LightEdit and launch errors.

Fixes #5885

Change

  • LaunchEditorInput gets an optional projectRoot, the workspace the target belongs to. The client sends it; the server never infers it from the path.
  • For JetBrains (line-column) editors, a positioned target puts the root first: idea <root> --line N --column C <file>. A target with no position keeps the old shape, because it may be a folder, which the IDE would open as a second project.
  • Chat file links pass the thread's workspace, and terminal links pass the thread's worktree, falling back to the terminal's folder. These are the two callers that send file:line[:col] targets. Diff, Git file actions, file preview and the Open in picker send no position, so they are unchanged.
  • VS Code (--goto), Zed and the other editors are unchanged.

Compatibility: the field is optional. An older server drops the unknown key on decode and launches the old shape. An older client sends no root and gets the old shape.

Scope and approval

This is a small fix for an obvious bug with an open report (#5885). It is one launch argument for one editor family, plus the two callers that already know the workspace. It adds no setting and changes no default. Mobile has no editor launch, and remote JetBrains (Gateway) uses a separate project-level link.

Prior PR: #7194 by @maslinedwin made the same fix and was closed for missing verification, not for its approach. This PR builds the change again on current main and credits that work. The verification below follows the closing note: focused launcher test results, and a positioned launch into worktree B while worktree A is already open.

Verification

Focused test (apps/server/src/process/externalLauncher.test.ts). The existing JetBrains macOS-bundle case now passes a project root and expects it first:

  • vp test run src/process/externalLauncher.test.ts -t "versioned macOS bundle" on main fails for both webstorm and idea: expected [ '--line', '12', '--column', …(2) ] to deeply equal [ '/workspace with spaces', …(5) ].
  • With the fix, the whole file passes: 26 of 26.
  • vp run check:changed: format, lint, knip, typecheck (37 packages), tests (7 files) and React compiler all pass.

Real IDE run (Linux, IntelliJ IDEA Community 2025.2.6.4 under Xvfb, T3 dev server, synthetic data only):

  1. A repo demo (branch main) plus a worktree demo-b (branch feature-b). Line 5 of src/Greeter.java differs between them.
  2. Open demo in IntelliJ.
  3. In T3, add demo-b as a project and start a thread whose message links src/Greeter.java:5:16. Choose Open in IntelliJ IDEA on the link. An idea wrapper on PATH logs its argv, then runs the real IDE.

Main:

1idea [--line] [5] [--column] [15] [/home/tester/work/demo-b/src/Greeter.java]

This branch:

1idea [/home/tester/work/demo-b] [--line] [5] [--column] [15] [/home/tester/work/demo-b/src/Greeter.java]

On this branch, IntelliJ asked where to open demo-b; I chose New Window. Afterwards both windows were open: demo and demo-b – Greeter.java.

A Ctrl+click on src/Greeter.java:3:14 printed in the thread's terminal launched idea [/home/tester/work/demo-b] [--line] [3] [--column] [13] [...Greeter.java].

The test thread lives in checkout B (demo-b). Its file link has an Open in IntelliJ IDEA action. Open in IntelliJ IDEA on a chat file link

Before: the file from checkout B opens inside the window for checkout A (demo, main), as a file outside that project. Before: file from checkout B in checkout A's window

After: IntelliJ opens checkout B as its own project (demo-b, feature-b) with the caret at 5:16. Checkout A stays open in its own window. After: checkout B opened as its own project

Not checked: macOS and Windows IDE runs (the argument shape is the same on every platform), JetBrains IDEs other than IntelliJ IDEA Community, and the terminal link on main (only the chat link ran on main).

Walkthrough

The editor launch request now supports an optional project root. Web editor links pass the effective workspace root, and the server includes it before positioned file arguments for JetBrains editors.

Changes: Project-root-aware editor launch

Layer / File(s)Summary
Carry the project root through the launch request
packages/contracts/src/editor.ts, apps/web/src/editorPreferences.ts, apps/web/src/components/ChatMarkdown.tsx, apps/web/src/components/ThreadTerminalDrawer.tsx		LaunchEditorInput accepts an optional, trimmed, non-empty projectRoot. The editor preference hook includes it when provided. Chat markdown passes cwd, and the terminal drawer passes worktreePath ?? cwd.
Add the root to positioned launch arguments
apps/server/src/process/externalLauncher.ts, apps/server/src/process/externalLauncher.test.ts		For positioned line-column targets, the server prepends the project root when one is defined. The test checks the root appears before the line, column, and file arguments.

Explanation

Issue #5885 requires the known project root before positioned JetBrains file arguments. The optional projectRoot field carries that root explicitly, and the launcher adds it for positioned line-column targets while preserving unpositioned targets. Chat passes cwd; terminal passes worktreePath ?? cwd. The launcher test now checks the root precedes the line, column, and file arguments. Diff and Git actions are reported as unpositioned, so they do not require the positioned-target argument change.

Preserve whitespace in project paths.

TrimmedNonEmptyString trims the value during encoding and decoding. (raw.githubusercontent.com) For a POSIX project root such as /work/demo , the launcher receives /work/demo and may open the wrong project or fail to open it. Validate that the path is nonblank without modifying it.

Note

🤖 Opus 5.5 replying on behalf of Victor.

Keeping TrimmedNonEmptyString here. The only values passed as projectRoot are the thread's worktreePath and the project's workspaceRoot. Both are already TrimmedNonEmptyString in contracts (orchestrationProject.ts, orchestrationV2.ts), so a root with surrounding whitespace never reaches this field. The sibling cwd field uses the same schema, so the request stays consistent with how every other path in it is typed.

@only21mil You’re right: the project workspace root and thread worktree path are already trimmed by their contracts. Changing projectRoot alone would not preserve whitespace for those paths. I withdraw the suggestion.

Verified in a real dev environment

verified head 76811052f82afe89d19ad6db27713aa367c1ef6a as-is on linux. no code changes were needed.

ran github/main (4c924ff4e6) in a separate worktree first, then the exact pr head, installing with vp i for each. used isolated state, the repo playwright dependency, and /usr/bin/google-chrome. added the real git checkout /home/user/editor-check-b through the app. real codex gpt-6.1-sol turns on both versions read src/Greeter.java and returned positioned markdown links. no replay provider, mocks, fixtures, or injected conversation data.

with checkout a already open in intellij idea community 2025.2.6.4:

  • main reproduced the bug through both the chat context-menu action and terminal ctrl-click: checkout b's file opened inside checkout a's project window.
  • the pr chat action opened checkout b as its own project after choosing new window. checkout a remained open. the file and caret were correct at 3:16.
  • terminal ctrl-click on the pr targeted checkout b's existing window and returned the caret to 3:16.
  • nearby behavior passed: the project-level open action still launched only the folder; a normal chat-link click opened the built-in file preview, and its open-file action launched only the file.

an idea wrapper logged arguments and then executed the real ide. observed transcript:

main opens checkout b file inside checkout a project

after: the same file and position inside checkout b's project.

pr opens checkout b file in checkout b project at 3:16

terminal ctrl-click through the real web client into intellij. inspected the recording and checked uploaded playback and seeking.

macos and windows editor launches, other jetbrains products, other editors in a real gui, the electron desktop client, remote or relay connections, and native ios/android clients were not exercised on this linux vm. mobile has no changed editor-launch caller. no performance claim is made.

@maria-rcks, thank you for testing exact head 7681105 against main in IntelliJ IDEA with real Codex turns. Your run reproduced the bug on main through both callers this PR changes, the chat Open in action and terminal Ctrl+click: checkout B's file opened inside checkout A's window. On the PR head the launch passed checkout B as the project first, so it opened as its own project with the caret at 3:16 and checkout A still open, and a later terminal Ctrl+click went to that same window.

Your run also covered the paths the PR leaves alone. The project-level open still launches only the folder, and the file preview's open action still launches only the file. That matches the description's point that a target with no position keeps the old shape.

Noted that macOS, Windows, other JetBrains products, other editors, Electron, remote connections and the native clients were outside this pass.
