Tab Project Grouper

In multi-root workspaces, keeps editor tabs grouped by their project (workspace folder) so you can tell at a glance which project a tab belongs to.

When you open a file, its tab is slid so it sits immediately to the right of the right-most already-open tab from the same project. If no tab from that project is open yet, the new tab goes to the far right of the group.

How it works

• Listens to vscode.window.tabGroups.onDidChangeTabs for single new opens.
• Determines a tab's project via workspace.getWorkspaceFolder(uri).
• Repositions the live tab using the built-in moveActiveEditor command — no closing/reopening, so no flicker or lost editor state.

Scope / limitations

• Groups a tab the moment it first becomes permanent — either it opens as a permanent tab, or a preview tab is promoted (edited / double-clicked). Transient preview tabs are never moved, so this works with preview-on-click either enabled or disabled.
• Each tab is positioned exactly once; it's never yanked around afterward on saves, focus changes, or if you manually reorder it.
• Bulk opens (session restore, "open folder") are left as-is.
• Only repositions the tab if it is the active tab of the active group (a moveActiveEditor constraint).
• Pinned tabs are left alone.
• Loose files outside any workspace folder share one <no project> bucket.
• Pairs well with "workbench.editor.labelFormat": "short", which prints the containing folder in each tab label.

Develop / run

npm install
npm run compile      # or: npm run watch

Then press F5 in VS Code to launch an Extension Development Host with the extension loaded. Open files from different projects in a multi-root workspace to see them group.

Commands

• Tab Project Grouper: Regroup all tabs by project — re-sorts every tab in the active group into contiguous per-project blocks (reopens editors in order; use when tabs have drifted out of grouping).

Settings

• tabProjectGrouper.enabled (default true) — toggle automatic repositioning.

Source & deployment

This directory is the editable source, kept in ~/vscode_lgenzelis_extensions/tab-project-grouper/ — separate from the installed copy VS Code loads (~/.vscode/extensions/lgenzelis.tab-project-grouper-0.0.1/).

Unlike the other two extensions, this is a TypeScript project. To compile and deploy your edits to the installed copy in one step:

./deploy.sh

deploy.sh runs npm run compile (src/ → out/), then installs a flat runtime copy: it copies out/extension.js, README.md, and a package.json with main rewritten to ./extension.js (and scripts/devDependencies stripped) into ~/.vscode/extensions/<publisher>.<name>-<version>/. Reload VS Code afterward (Cmd+Shift+P → Developer: Reload Window). Bumping version in package.json creates a new versioned install folder.
