--filter <name> cannot select the root project (single-package project, or workspace root)

• aube: 2.7.0 linux-x64 (2026-10-07)
• pnpm (control): 12.11.2
• Repro: https://github.com/mwolson/tmp-aube-issues/tree/main/filter-root-project

aube --filter <name> fails when <name> is the root project. pnpm selects it in both of these setups.

Single-package project (one package.json named app, no workspace file):

pnpm --filter app run hello   # $ echo hello from app
aube --filter app run hello

  × aube run: --filter requires a workspace root (aube-workspace.yaml, pnpm-
  │ workspace.yaml, or package.json with a `workspaces` field) at or above ...

aube --filter app exec ..., aube --filter app list, and aube -F app test fail the same way.

pnpm workspace root (root package.json named root, pnpm-workspace.yaml with packages/*, one member):

pnpm --filter root run hello   # $ echo hello from root
aube --filter root run hello

  × aube run: filter EffectiveFilter { filters: ["root"], filter_prods: [],
  │ fail_if_no_match: false, include_workspace_root: false } did not match any
  │ workspace package

That message also prints the internal EffectiveFilter debug struct where a user-facing description belongs.

The workspaces docs list exact package names as a selector form and don't mention needing a workspace. Both errors come from select_workspace_packages in crates/aube/src/commands/workspace_helpers.rs, which only considers workspace members and errors out when there are none.

Expected: like pnpm, treat the root project as selectable by name, both when it is the only project and when it is a workspace root.

I found this through aubeshim, which routes bun run --filter <pkg> <script> to aube run. Bun 1.4.3 also runs the root script in a single-package project.

To reproduce:

git clone https://github.com/mwolson/tmp-aube-issues
cd tmp-aube-issues/filter-root-project
./repro.sh

Thanks for the clear repro. Fixed in #1754: an explicit --filter <name> (or --filter ./) now selects the root project, both in a single-package project and in a workspace root, across run, exec, list, why, query and friends. -r and --filter '*' still exclude the root, as in pnpm. The no-match error also no longer prints the EffectiveFilter debug struct.

Retested with aube 2.8.0 linux-x64 (2026-10-19):

• Repo: https://github.com/mwolson/tmp-aube-issues
• Case: filter-root-project

PNPM_BIN=/path/to/real/pnpm ./repro.sh

It now exits 0 with native pnpm 12.14.0 as the control. aube --filter app run hello in the single-package project and aube --filter root run hello in the workspace both run the root script. Same result on 2.7.2.

Fix shipped in aube 2.7.2 via #1754. Marking your reply as the answer.
