Overview + +The `sproto.yaml` file resides at the root of a Protobuf module directory. It defines metadata about the module, including its name, import path, and dependencies on other SProto modules. This file enables SProto's dependency management features. + +## 2. Format Version + +The configuration format is versioned to allow for future changes. + +- **`version`** (Required, String): Specifies the version of the `sproto.yaml` schema being used. The current version is `"v1"`. + ```yaml + version: v1 + ``` + +## 3. Module Definition + +These fields define the identity and import path of the current module. + +- **`name`** (Required, String): A unique identifier for the module within the SProto registry, following the format `"namespace/name"`. + - `namespace`: Typically represents an organization, team, or user. + - `name`: The specific name of the module. + - Example: `"mycompany/user_service"` + ```yaml + name: mycompany/user_service + ``` + +- **`import_path`** (Required, String): The base Go-style import path prefix for the `.proto` files within this module. This allows SProto (and potentially other tools) to correctly resolve `import` statements in Protobuf files. + - Example: `"github.com/mycompany/user_service/proto"` + ```yaml + import_path: github.com/mycompany/user_service/proto + ``` + If a `.proto` file within this module is located at `proto/v1/user.proto`, its full import path would be `github.com/mycompany/user_service/proto/v1/user.proto`. + +## 4. Dependencies + +This section lists other SProto modules that the current module depends on. + +- **`dependencies`** (Optional, Array): A list of module dependencies. If omitted or empty, the module has no declared dependencies. + ```yaml + dependencies: + - namespace: mycompany + name: common_types + version: "v1.2.0" # Specific version + import_path: github.com/mycompany/common_types/proto + - namespace: external_org + name: public_apis + version: ">=v2.0.0, =v1.1.0"`, `"~v1.2.0"`).

[Examples](#examples) + +## Introduction + +Version constraints allow you to specify which versions of a dependency your module is compatible with. SProto uses semantic versioning (SemVer) for all version constraints, providing flexibility and precision in dependency management. + +In your `sproto.yaml` file, version constraints are specified in the `version` field of each dependency: + +```yaml +dependencies: + - namespace: mycompany + name: common + version: ">=v1.0.0, ` | `>v1.0.0` | Greater than the specified version | +| `>=` | `>=v1.0.0` | Greater than or equal to the specified version | +| `<` | `=v1.2.0, =v1.2.0, `)**: Requires a version higher than the specified version. + - Example: `>v1.2.3` allows any version above `v1.2.3` (`v1.2.4`, `v1.3.0`, `v2.0.0`, etc.) + +- **Greater Than or Equal To (`>=`)**: Requires a version equal to or higher than the specified version. + - Example: `>=v1.2.3` allows `v1.2.3` and any higher version + +- **Less Than (`<`)**: Requires a version lower than the specified version. + - Example: `=v1.2.3, =v1.2.3, =v0.2.3, =v0.0.3, =v1.0.0, =v1.0.0, =v1.0.0, v1.3.0, v1.2.0, <=v1.5.0` (any version greater than `v1.2.0` and less than or equal to `v1.5.0`) + +## Semantics and Resolution Rules + +When SProto resolves dependencies, it follows these rules: + +1. **Satisfaction**: A version satisfies a constraint if it meets all the conditions in the constraint. +2. **Version Selection**: If multiple versions satisfy the constraints, SProto selects the highest version. +3. **Pre-releases**: Pre-release versions are only selected if explicitly requested in the constraint. +4. **Conflict Resolution**: If conflicting constraints are found (no version satisfies all constraints), SProto reports an error. +5. **Transitive Dependencies**: Constraints from all modules in the dependency graph are considered when resolving a specific dependency. + +### Constraint Evaluation Order + +1. The exact constraints are evaluated first (`=v1.2.3`) +2. Range constraints are evaluated next (`>`, `>=`, `<`, `<=`) +3. Semantic operators (`~`, `^`) are expanded to their equivalent ranges and then evaluated + +## Best Practices + +1. **Use version ranges wisely**: + - Prefer `^v1.0.0` for most dependencies (allows compatible updates) + - Use `~v1.2.0` when you want only patch updates + - Use explicit constraints (`=v1.2.3`) for critical dependencies where you need exact control + +2. **Avoid overly restrictive constraints**: + - `=v1.2.3` might lead to dependency conflicts in large projects + - Consider the impact on transitive dependencies + +3. **Follow SemVer conventions**: + - Major version changes (`v1.0.0` to `v2.0.0`) indicate breaking changes + - Minor version changes (`v1.1.0` to `v1.2.0`) indicate new features without breaking changes + - Patch version changes (`v1.1.1` to `v1.1.2`) indicate bug fixes + +4. **Use narrow constraint ranges for unstable dependencies**: + - For modules that don't strictly follow SemVer, use narrower constraints + +## Examples + +### Basic Dependencies + +```yaml +dependencies: + # Exact version + -
