🌐 Web query:

For the pnpm versions supported by this repository, can .npmrcusehoist-pattern[]orpublic-hoist-pattern[]? Provide the applicable official documentation.

💡 Result:

Yes, the hoist-pattern[] and public-hoist-pattern[] configurations are supported in .npmrc files, although the official pnpm documentation primarily recommends configuring these settings in pnpm-workspace.yaml or a global configuration file (~/.config/pnpm/config.yaml) for better stability and clarity [1][2]. While these settings are technically supported via the .npmrc file using the array syntax (e.g., hoist-pattern[]=...) [3][4], they are often categorized under workspace-specific settings [2]. According to official pnpm documentation, most settings outside of authentication, registry, and proxy configuration should be placed in pnpm-workspace.yaml [1][2]. Important considerations when using these settings in .npmrc: 1. Usage Context: If you are using a pnpm workspace, the settings should ideally reside in your pnpm-workspace.yaml [1][2]. 2. Compatibility Risks: Defining these settings in .npmrc has historically caused issues when pnpm is invoked through tools like npx or certain npm scripts, as the underlying environment may incorrectly parse or override the array-based settings [4]. 3. Syntax: When used in .npmrc, the syntax requires the [] suffix to denote an array, for example: public-hoist-pattern[]=*types* [3]. You can find further details in the official documentation regarding node-modules and hoisting settings at: https://pnpm.io/settings/node-modules

Recognize array-valued layout settings.

When the pnpm version accepts hoist-pattern[] or public-hoist-pattern[] in .npmrc, layoutKeyPattern does not match the [] suffix. projectManagesOwnHoisting then returns false, so install adds --shamefully-hoist. This can trigger the non-interactive layout conflict.

Allow an optional [] suffix and add tests for both keys.

In `@lib/pnpm-package-manager.ts` at line 175, Update layoutKeyPattern in
projectManagesOwnHoisting to match an optional [] suffix for array-valued
hoist-pattern and public-hoist-pattern settings, while preserving existing
scalar-key matches. Add tests covering both array-valued keys and verify install
does not add --shamefully-hoist when either is configured.
