+# Optional --version with semantic-release (both workflows)
+
+## Scope: two workflows
+
+1. **Workflow 1 – Publishing a subfolder** (monorepo): Build and publish a subfolder of `src/` as its own package. Version today is required via `--version`.
+2. **Workflow 2 – Building packages with shared code**: Build the main package (e.g. `src/my_package/`) that imports from `shared/`. Version today comes from `pyproject.toml` (dynamic or static) or `--version` when publishing.
+
+Both workflows should support **optional `--version**`: when omitted, resolve the next version via semantic-release and use it for the build/publish.
+
+## Current behavior
+
+- **CLI** ([`python_package_folder.py`](src/python_package_folder/python_package_folder.py)): For subfolder builds, `--version` is required; the tool exits with an error if it is missing (lines 158–164). For main-package builds, `--version` is optional; version comes from `pyproject.toml` or user.
+- **Manager** ([`manager.py`](src/python_package_folder/manager.py)): `prepare_build` defaults version to `"0.0.0"` with a warning when `version` is `None` for subfolders (lines 232–239). `build_and_publish` raises `ValueError` if `version` is missing for a subfolder build (lines 1254–1258). For main package, `version` can be None (no error); then publish uses whatever the build produced (dynamic versioning or static from pyproject).
+- **Publisher** ([`publisher.py`](src/python_package_folder/publisher.py)): Filters dist files by `package_name` and `version`; both are required for reliable filtering.
+
+## Target behavior
+
+- `**--version` optional for both workflows**: If `--version` is not provided and a version is needed (subfolder build, or main-package publish), compute the next version using semantic-release, then proceed with that version. If provided, keep current behavior (explicit version).
+- **Workflow 1 (subfolder)**: Per-package tags `{package-name}-v{version}` and commits filtered to the subfolder path.
+- **Workflow 2 (main package)**: Repo-level tags (e.g. `v{version}`), no path filter; run semantic-release from project root.
+
+## Architecture

+  A --> B --> C
+  B --> Node[Node: get-next-version script]
+  Node --> SR[semantic-release dry-run]
+  SR --> NextVer[Next version]
+  NextVer --> C
+```
+
+- **Version resolution**: When `--version` is missing and needed (subfolder build, or main-package publish), call a Node script that runs semantic-release in dry-run and prints the next version to stdout.
+  - **Workflow 1**: Script runs with subfolder path and package name → per-package tag format and path-filtered commits (semantic-release-commit-filter).
+  - **Workflow 2**: Script runs from project root, no path filter → default tag format `v{version}`; package name from `pyproject.toml` for Publisher filtering only.
+- **Fallback**: If Node/semantic-release is unavailable or semantic-release decides there is no release, fail with a clear message and suggest installing semantic-release (and commit-filter for subfolders) or passing `--version` explicitly.
+
+## Implementation options for “get next version”
+
+- **Option A (recommended): Small Node script using semantic-release API**  
+
+Add a script (e.g. `scripts/get-next-version.cjs` or under `.release/`) that:
+
+  - Takes args: project root, subfolder path (relative or absolute), package name.
+  - Ensures a minimal `package.json` exists in the subfolder (or in a temp location with correct `name`) so that semantic-release-commit-filter can use `package.name` for `tagFormat` and filter commits by cwd.
+  - Requires semantic-release and semantic-release-commit-filter, runs semantic-release programmatically with `dryRun: true`, and prints `nextRelease.version` (or “none”) to stdout.  
+
+This avoids parsing human-oriented dry-run output and gives a single, stable contract.
+
+- **Option B: Parse `npx semantic-release --dry-run` output**  
+
+Run the CLI in dry-run and parse stdout. Possible but brittle (format can change, localization, etc.). Not recommended.
+
+## Key implementation details
+
+1. **Where to run semantic-release**
+
+Run from the **subfolder** directory so that semantic-release-commit-filter’s “current directory” is the subfolder and commits are filtered to that path. Tag format will be `{package.name}-v${version}` from the `package.json` in that directory.
+
+2. **Temporary `package.json` in subfolder**
+
+Python subfolders usually have no `package.json`. Create a temporary one for the version resolution only: `{"name": "<package_name>"}` (same name as used for the Python package). Run semantic-release from the subfolder, then remove the temp file (or overwrite only if we created it). Document that the script may create/remove `package.json` in the subfolder so users are not surprised.
+
+3. **Dependencies**
+
+  - No new Python dependencies.  
+  - Document that **Node.js** and **npm** (or **npx**) must be available when using auto-versioning.  
+  - Document (and optionally script) install of semantic-release and semantic-release-commit-filter, e.g. `npm install -g semantic-release semantic-release-commit-filter` or per-repo `package.json` with these as devDependencies.
+
+4. **CLI flow**
+
+  - If subfolder build and `args.version` is None:  
+    - Call the version resolver (subprocess: `node scripts/get-next-version.cjs <project_root> <subfolder_path> <package_name>`).  
+    - If resolver returns a version string: use it for the rest of the flow.  
+    - If resolver returns “none” or fails (no release / semantic-release not found / Node error): exit with a clear error suggesting to pass `--version` or to install and configure semantic-release.
+  - Pass the resolved or explicit version into `build_and_publish` / `prepare_build` as today.
+
+5. **Manager / Publisher**
+
+No change to the contract: they still receive a concrete `version` (either from CLI or from the resolver). Only the CLI and the new resolution step change.
+
+6. **Convention**
+
+Rely on default Angular/conventional commit rules (e.g. `fix:` → patch, `feat:` → minor, `BREAKING CHANGE:` → major). Document that conventional commits are required for auto-versioning; no change to commit format inside this repo unless you add a config file for semantic-release.

+
+## Open decisions
+
+- **Script location**: Ship `get-next-version.cjs` inside this repo under `scripts/` (or `.release/`) so that `python-package-folder` can invoke it without requiring the user to add it. The script will `require('semantic-release')` and `require('semantic-release-commit-filter')`; users must have these installed (globally or in a local `package.json` at project root or subfolder).
+- **First release / no tag**: If there is no tag for this package yet, semantic-release will use an initial version (e.g. 1.0.0). Confirm desired behavior (e.g. configurable first version or always 1.0.0).
+- **No release (no relevant commits)**: If semantic-release determines there is no release, the script should output something like “none” and the CLI should exit with a clear message rather than defaulting to 0.0.0.
+
+## Summary
+
+- Make `--version` optional for subfolder builds by resolving the next version via Node.js semantic-release with per-package tags and path-filtered commits.
+- Add a small Node script that runs semantic-release in dry-run and prints the next version; wire it from the CLI when `--version` is omitted.
+- Document Node/npm and semantic-release (and semantic-release-commit-filter) as requirements for this mode, and keep explicit `--version` as the fallback when auto-versioning is not available or not desired.

+### Automatic Version Resolution (semantic-release)
+
+When `--version` is not provided, the tool can automatically determine the next version using semantic-release. This requires Node.js, npm, and semantic-release to be installed.
+
+**For subfolder builds (Workflow 1):**
+- Uses per-package tags: `{package-name}-v{version}` (e.g., `my-package-v1.2.3`)
+- Filters commits to only those affecting the subfolder path
+- Requires `semantic-release-commit-filter` plugin
+
+**For main package builds (Workflow 2):**
+- Uses repo-level tags: `v{version}` (e.g., `v1.2.3`)
+- Analyzes all commits in the repository
+
+**Setup:**
+```bash
+# Install semantic-release globally
+npm install -g semantic-release
+
+# For subfolder builds, also install semantic-release-commit-filter
+npm install -g semantic-release-commit-filter
+```
+
+**Usage:**
+```bash
+# Subfolder build - version resolved automatically
+cd src/my_subfolder
+python-package-folder --publish pypi
+
+# Main package - version resolved automatically
+python-package-folder --publish pypi
+```
+
+**Requirements:**
+- Conventional commits (e.g., `fix:`, `feat:`, `BREAKING CHANGE:`) are required for semantic-release to determine version bumps
+- The tool will fall back to requiring `--version` explicitly if semantic-release is not available or determines no release is needed
+
 ### Subfolder Versioning
 
 When building from a subdirectory (not the main `src/` directory), the tool automatically detects the subfolder and sets up the build configuration:
 
 ```bash
-# Build a subfolder as a separate package (version recommended but not required)
+# Build a subfolder as a separate package with explicit version
 cd my_project/subfolder_to_build
 python-package-folder --version "1.0.0" --publish pypi
 
+# Or let semantic-release determine the version automatically
+python-package-folder --publish pypi
+
 # With custom package name
 python-package-folder --version "1.0.0" --package-name "my-custom-name" --publish pypi
-
-# Version defaults to "0.0.0" if not specified (with a warning)
-python-package-folder --publish pypi
 ```
 
 For subfolder builds:
 - **Automatic detection**: The tool automatically detects subfolder builds
+- **Version resolution**: 
+  - If `--version` is provided: Uses the explicit version
+  - If `--version` is omitted: Attempts to resolve via semantic-release (requires setup)
+  - If semantic-release is unavailable or determines no release: Requires `--version` explicitly
 - **pyproject.toml handling**:
   - If `pyproject.toml` exists in subfolder: Uses that file (copied to project root temporarily)
   - If no `pyproject.toml` in subfolder: Creates temporary one with correct package structure
-- **Version**: Recommended but not required when creating temporary pyproject.toml. If not provided, defaults to `0.0.0` with a warning. Ignored if subfolder has its own `pyproject.toml`.
 - **Package name**: Automatically derived from the subfolder name (e.g., `subfolder_to_build` → `subfolder-to-build`). Only used when creating temporary pyproject.toml.
 - **Restoration**: Original `pyproject.toml` is restored after build
 - **Temporary configuration**: Creates a temporary `pyproject.toml` with:
   - Custom package name (from `--package-name` or derived)
-  - Specified version
+  - Specified or resolved version
   - Correct package path for hatchling
   - Dependency group from parent (if `--dependency-group` is specified)

+/**
+ * Get next version using semantic-release.
+ * 
+ * This script runs semantic-release in dry-run mode to determine the next version
+ * for a package. It supports both subfolder builds (per-package tags) and main
+ * package builds (repo-level tags).
+ * 
+ * Usage:
+ *   node scripts/get-next-version.cjs <project_root> [subfolder_path] [package_name]
+ * 
+ * Args:
+ *   - project_root: Root directory of the project (absolute or relative path)
+ *   - subfolder_path: Optional. Path to subfolder relative to project_root (for Workflow 1)
+ *   - package_name: Optional. Package name for subfolder builds (for per-package tags)
+ * 
+ * Output:
+ *   - Version string (e.g., "1.2.3") if a release is determined
+ *   - "none" if semantic-release determines no release is needed
+ *   - Exits with non-zero code on error
