feat(task): add [monorepo].config_roots for explicit config root listing by jdx · Pull Request #7705 · jdx/mise

jdx · 2026-01-17T14:31:56Z

Summary

Add [monorepo].config_roots to mise.toml for explicitly listing monorepo config roots
Skip filesystem walking when config_roots is defined for better performance
Support single-level glob patterns (*) for flexible path matching
Deprecate automatic filesystem discovery with a warning

Usage

# mise.toml
experimental_monorepo_root = true

[monorepo]
config_roots = [
    "packages/frontend",
    "packages/backend",
    "services/*",          # Single-level glob
]

Test plan

E2E test test_task_monorepo_config_roots covers explicit paths, globs, and exclusion
Existing monorepo tests continue to pass (with deprecation warning)

🤖 Generated with Claude Code

Note

Monorepo task discovery overhaul

Introduces [monorepo].config_roots in mise.toml (schema + parsing) to explicitly list config roots; supports single-level * globs
Loader now expands config_roots and loads tasks from those dirs; falls back to deprecated auto-walk with a warning
New helpers: find_monorepo_config, expand_config_roots, has_mise_config; plumbs monorepo through config structs
Updates docs to a new Config Roots section describing usage, benefits, and deprecation of auto discovery
E2E: adds test_task_monorepo_config_roots and updates existing monorepo tests to specify config_roots

The unwrap_or("") fallback for invalid UTF-8 paths could lead to incorrect filtering behavior. Consider handling this case more explicitly or documenting the assumption that paths are valid UTF-8.

This helper function lacks documentation explaining its purpose and the source of DEFAULT_CONFIG_FILENAMES. Add a doc comment describing what constitutes a 'mise config' and which filenames are checked.

The documentation should clarify what happens when config_roots is empty versus when the entire [monorepo] section is absent, as these scenarios may have different behaviors based on the implementation in discover_monorepo_subdirs.

Suggested change

pub struct MonorepoConfig {

/// Explicit list of config roots for monorepo task discovery.

/// Supports single-level glob patterns (*).

/// Configuration for the `[monorepo]` section in `mise.toml`.

///

/// Behavior notes:

/// - If the entire `[monorepo]` section is **omitted** from `mise.toml`,

/// the monorepo discovery logic in `discover_monorepo_subdirs` will fall

/// back to its default behavior (for example, using built‑in conventions

/// for locating project/task configuration).

/// - If `[monorepo]` is present but `config_roots = []` is specified

/// explicitly, this deserializes as an explicit empty list and is passed

/// through to `discover_monorepo_subdirs`, allowing it to distinguish

/// "no override / use defaults" from "no config roots".

#[derive(Debug, Default, Clone, Deserialize)]

pub struct MonorepoConfig {

/// Explicit list of config roots for monorepo task discovery.

///

/// Supports single-level glob patterns (`*`).

///

/// When omitted, this field defaults to an empty list via `#[serde(default)]`.

/// The caller of `MonorepoConfig` (notably `discover_monorepo_subdirs`)

/// is responsible for deciding how to interpret an empty list, which may

/// differ from the behavior when the entire `[monorepo]` section is absent.

+            } else {
+                path.parent().unwrap_or(&path).join(&target)


Using unwrap_or(&path) when parent() returns None could create a confusing path if the install is at the filesystem root. Consider handling this edge case more explicitly or adding a comment explaining why this fallback is safe.

Suggested change

path.parent().unwrap_or(&path).join(&target)

// For relative symlinks, resolve them relative to the directory

// containing `path`. If `path` has no parent, it must be at the

// filesystem root (e.g. "/"), and relative symlink targets are

// then resolved relative to that root.

match path.parent() {

Some(parent) => parent.join(&target),

None => PathBuf::from("/").join(&target),

+::: warning Automatic Discovery Deprecated
+Automatic filesystem walking to discover monorepo subdirectories is deprecated. If you don't define `[monorepo].config_roots`, mise will still walk the filesystem but will emit a deprecation warning. Please migrate to explicit config roots.


The deprecation notice should include information about when this feature will be removed (if planned) to help users understand the urgency of migrating.

Automatic filesystem walking to discover monorepo subdirectories is deprecated. If you don't define `[monorepo].config_roots`, mise will still walk the filesystem but will emit a deprecation warning. Please migrate to explicit config roots. There is currently no scheduled removal date for this behavior, but it may be removed in a future major release, so plan your migration accordingly.

Add a new `[monorepo]` section to mise.toml that allows explicitly listing config roots for monorepo task discovery. This provides better performance by skipping filesystem walking. Features: - Explicit path listing: `config_roots = ["packages/frontend", "packages/backend"]` - Single-level glob support: `config_roots = ["services/*"]` - Deprecation warning when falling back to automatic discovery Automatic filesystem walking for monorepo discovery is now deprecated.

Update all monorepo e2e tests to explicitly define config_roots instead of relying on automatic filesystem discovery (which is now deprecated). Also extends has_mise_config() to recognize directories with .mise/tasks or mise-tasks directories for consistency with auto-discovery behavior.

Empty config_roots falls back to deprecated walking unexpectedly

Low Severity

When config_roots = [] is explicitly set, the code falls back to deprecated filesystem walking instead of returning an empty list. The comment says "If [monorepo].config_roots is defined, use explicit paths" but the condition !patterns.is_empty() treats an empty array as "not defined." A user setting config_roots = [] would expect zero subdirs discovered, but instead gets all subdirs via deprecated walking plus a deprecation warning.

+            }
+        }
+    }


Missing root exclusion allows duplicate task loading

Low Severity

The expand_config_roots function lacks a check to exclude the monorepo root from the returned subdirs. Patterns like "", ".", or "subdir/.." could cause the root directory to be added to subdirs. The deprecated filesystem walking code explicitly skips the root (via if dir == root { continue; } and min_depth(1)), but this new function doesn't. When root is included in subdirs, its tasks get loaded twice, causing duplicate entries.

chore(mise): use explicit monorepo config immich-app/immich#25575

Merged

-/// Configuration for [monorepo] section in mise.toml
-#[derive(Debug, Default, Clone, Deserialize)]
-pub struct MonorepoConfig {
-    /// Explicit list of config roots for monorepo task discovery.
-    /// Supports single-level glob patterns (*).
+/// Configuration for the `[monorepo]` section in `mise.toml`.
+///
+/// Behavior notes:
+/// - If the entire `[monorepo]` section is **omitted** from `mise.toml`,
+///   the monorepo discovery logic in `discover_monorepo_subdirs` will fall
+///   back to its default behavior (for example, using built‑in conventions
+///   for locating project/task configuration).
+/// - If `[monorepo]` is present but `config_roots = []` is specified
+///   explicitly, this deserializes as an explicit empty list and is passed
+///   through to `discover_monorepo_subdirs`, allowing it to distinguish
+///   "no override / use defaults" from "no config roots".

+    ///
+    /// When omitted, this field defaults to an empty list via `#[serde(default)]`.
+    /// The caller of `MonorepoConfig` (notably `discover_monorepo_subdirs`)
+    /// is responsible for deciding how to interpret an empty list, which may
+    /// differ from the behavior when the entire `[monorepo]` section is absent.

+                // For relative symlinks, resolve them relative to the directory
+                // containing `path`. If `path` has no parent, it must be at the
+                // filesystem root (e.g. "/"), and relative symlink targets are
+                // then resolved relative to that root.
+                match path.parent() {
+                    Some(parent) => parent.join(&target),

	Automatic filesystem walking to discover monorepo subdirectories is deprecated. If you don't define `[monorepo].config_roots`, mise will still walk the filesystem but will emit a deprecation warning. Please migrate to explicit config roots.

There is currently no scheduled removal date for this behavior, but it may be removed in a future major release, so plan your migration accordingly.
