setup / doctor — Tool Management with mise

sayt setup installs project toolchains. sayt doctor verifies each environment tier is ready.

How It Works

1. sayt setup looks for .mise.toml in the current directory
2. Runs mise trust -y -a -q to trust the config
3. Runs mise install to install all specified tools
4. Preloads vscode-task-runner (vtr) into the uvx cache for offline use
5. If .sayt.nu exists, recursively calls it with setup for custom logic

sayt doctor checks which environment tiers have their required tools available:

.mise.toml File Format

mise uses TOML configuration to specify tool versions per project.

Structure

[settings]
locked = true           # Use lockfile for reproducible installs
lockfile = true         # Generate/use mise.lock
experimental = true     # Enable experimental features
paranoid = false        # Disable paranoid mode

[tools]
# Standard registry tools
node = "22.14.0"
go = "1.22"
java = "openjdk-21.0"
python = "3.12"

# GitHub-hosted tools (not in default registry)
"github:pnpm/pnpm" = "9.15.2"
"github:sqlc-dev/sqlc" = "1.28.0"
"github:bufbuild/buf" = "1.32.1"

Settings Reference

[settings]
locked = true                       # Require lockfile to exist
lockfile = true                     # Create/update mise.lock
experimental = true                 # Needed for some plugin features
paranoid = false                    # Don't verify checksums aggressively
github.slsa = false                 # Skip SLSA provenance verification
github.github_attestations = false  # Skip GitHub attestations
aqua.github_attestations = false    # Skip aqua GitHub attestations
aqua.cosign = false                 # Skip cosign verification
aqua.slsa = false                   # Skip aqua SLSA verification
aqua.minisign = false               # Skip minisign verification

These security settings are commonly disabled during development for speed. Enable them in CI/production.

Common Tool Specs

Node.js project:

[tools]
node = "22.14.0"
"github:pnpm/pnpm" = "9.15.2"

Go project:

[tools]
go = "1.22"
"github:sqlc-dev/sqlc" = "1.28.0"
"github:gotestyourself/gotestsum" = "1.12.0"

JVM project:

[tools]
java = "openjdk-21.0"

Python project:

[tools]
python = "3.12"

Multi-language project:

[tools]
node = "22.14.0"
go = "1.22"
"github:bufbuild/buf" = "1.32.1"

Platform-Specific Stubs

sayt uses mise "tool stubs" for tools like CUE, Docker, and uvx. These have platform-specific TOML configs:

• cue.toml — Standard CUE stub
• cue.musl.toml — Alpine/musl Linux variant
• docker.toml / docker.musl.toml — Docker stub
• uvx.toml / uvx.musl.toml — Python uvx stub
• nu.toml / nu.musl.toml — Nushell stub

The musl variant is automatically selected when running on musl-based Linux (e.g., Alpine containers).

Custom Setup Logic via .sayt.nu

If your project needs setup beyond what mise provides, create .sayt.nu:

# .sayt.nu — Custom setup hooks
def "main setup" [] {
    # Example: install Nix packages
    nix-env -iA nixpkgs.myTool

    # Example: run database migrations
    sqlc generate
}

sayt automatically detects and runs .sayt.nu setup after the mise-based setup completes.

Writing Good .mise.toml Files

1. Pin exact versions — Use "22.14.0" not "22" for reproducibility
2. Use lockfiles — Set locked = true and lockfile = true
3. Prefer registry names — Use node not "github:nodejs/node" when available
4. Use github: prefix — For tools not in the default mise registry
5. Keep settings section — Even if using defaults, be explicit about security settings
