Profile Selection

Profiles provide built-in recipes. Supported profiles are go, node, and rust.

Profile selection precedence is:

1. explicit --profile
2. config profile
3. marker detection only when no config is loaded

shadowtree --profile go recipes
shadowtree --profile node --print build
shadowtree --profile rust --print check

profile = "go"

Marker Detection

When no config file is loaded, Shadowtree walks upward from the current directory and compares the nearest profile markers. The walk stops at the current repository root.

• package.json selects node.
• go.mod or go.work selects go.
• Cargo.toml selects rust.
• Same-directory precedence is Go, then Node, then Rust.

Configs that omit profile suppress detected built-ins. This preserves exact configured recipe sets unless a config opts into a profile.

Inspecting Profiles

Use inspection commands to see exact built-ins for the current checkout:

shadowtree recipes
shadowtree --print test
shadowtree --print --expanded test
shadowtree --check --shell test

Profile-specific behavior:

• Go Profile
• Node Profile
• Rust Profile
