Enum ResourceDependency 

pub enum ResourceDependency {
    Simple(String),
    Detailed(Box<DetailedDependency>),
}

A resource dependency specification supporting multiple formats.

Dependencies can be specified in two main formats to balance simplicity with flexibility. The enum uses Serde’s untagged attribute to automatically deserialize the correct variant based on the TOML structure.

Variants

Simple(String)

Simple path-only dependency, typically for local files.

This variant represents the simplest dependency format where only a file path is specified. It’s primarily used for local dependencies that exist in the filesystem relative to the project.

Format

dependency-name = "path/to/file.md"

Examples

[agents]
# Relative paths from manifest directory
helper = "../shared/helper.md"
custom = "./local/custom.md"

# Absolute paths (not recommended)
system = "/usr/local/share/agent.md"

Limitations

• Cannot specify version constraints
• Cannot reference remote Git sources
• Must be a valid filesystem path
• Path must exist at installation time

Detailed(Box<DetailedDependency>)

Detailed dependency specification with full control.

This variant provides complete control over dependency specification, supporting both local and remote dependencies with version constraints, Git references, and explicit source mapping.

See DetailedDependency for field-level documentation.

Note: This variant is boxed to reduce the overall size of the enum.

Implementations

impl ResourceDependency

pub fn get_source(&self) -> Option<&str>

Get the source repository name if this is a remote dependency.

Returns the source name for remote dependencies (those that reference a Git repository), or None for local dependencies (those that reference local filesystem paths).

Examples

use agpm_cli::manifest::{ResourceDependency, DetailedDependency};

// Local dependency - no source
let local = ResourceDependency::Simple("../local/file.md".to_string());
assert!(local.get_source().is_none());

// Remote dependency - has source
let remote = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: Some("official".to_string()),
    path: "agents/tool.md".to_string(),
    version: Some("v1.0.0".to_string()),
    branch: None,
    rev: None,
    command: None,
    args: None,
    target: None,
    filename: None,
    dependencies: None,
    tool: Some("claude-code".to_string()),
    flatten: None,
    install: None,
    template_vars: Some(serde_json::Value::Object(serde_json::Map::new())),
}));
assert_eq!(remote.get_source(), Some("official"));
assert_eq!(remote.get_source(), Some("official"));

Use Cases

This method is commonly used to:

• Determine if dependency resolution should use Git vs filesystem
• Validate that referenced sources exist in the manifest
• Filter dependencies by type (local vs remote)
• Generate dependency graphs and reports

pub fn get_target(&self) -> Option<&str>

Get the custom target directory for this dependency.

Returns the custom target directory if specified, or None if the dependency should use the default installation location for its resource type.

Examples

use agpm_cli::manifest::{ResourceDependency, DetailedDependency};

// Dependency with custom target
let custom = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: Some("official".to_string()),
    path: "agents/tool.md".to_string(),
    version: Some("v1.0.0".to_string()),
    target: Some("custom/tools".to_string()),
    branch: None,
    rev: None,
    command: None,
    args: None,
    filename: None,
    dependencies: None,
    tool: Some("claude-code".to_string()),
    flatten: None,
    install: None,
    template_vars: Some(serde_json::Value::Object(serde_json::Map::new())),
}));
assert_eq!(custom.get_target(), Some("custom/tools"));

// Dependency without custom target
let default = ResourceDependency::Simple("../local/file.md".to_string());
assert!(default.get_target().is_none());

pub fn get_tool(&self) -> Option<&str>

Get the tool for this dependency.

Returns the tool string if specified, or None if not specified. When None is returned, the caller should apply resource-type-specific defaults.

Returns

• Some(tool) if tool is explicitly specified
• None if no tool is configured (use resource-type default)

pub fn set_tool(&mut self, tool: Option<String>)

Set the tool for this dependency.

Only works for Detailed dependencies. Does nothing for Simple dependencies.

pub fn get_filename(&self) -> Option<&str>

Get the custom filename for this dependency.

Returns the custom filename if specified, or None if the dependency should use the default filename based on the dependency key.

Examples

use agpm_cli::manifest::{ResourceDependency, DetailedDependency};

// Dependency with custom filename
let custom = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: Some("official".to_string()),
    path: "agents/tool.md".to_string(),
    version: Some("v1.0.0".to_string()),
    filename: Some("ai-assistant.md".to_string()),
    branch: None,
    rev: None,
    command: None,
    args: None,
    target: None,
    dependencies: None,
    tool: Some("claude-code".to_string()),
    install: None,
    flatten: None,
    template_vars: Some(serde_json::Value::Object(serde_json::Map::new())),
}));
assert_eq!(custom.get_filename(), Some("ai-assistant.md"));

// Dependency without custom filename
let default = ResourceDependency::Simple("../local/file.md".to_string());
assert!(default.get_filename().is_none());

pub fn get_flatten(&self) -> Option<bool>

Get the flatten flag for this dependency.

Returns the flatten setting if explicitly specified, or None if the dependency should use the default flatten behavior based on tool configuration.

When flatten = true: Only the filename is used (e.g., nested/dir/file.md → file.md) When flatten = false: Full path is preserved (e.g., nested/dir/file.md → nested/dir/file.md)

Default Behavior (from tool configuration)

• Agents: Default to true (flatten)
• Commands: Default to true (flatten)
• All others: Default to false (preserve structure)

pub fn get_install(&self) -> Option<bool>

Get the install flag for this dependency.

Returns the install setting if explicitly specified, or None to use the default behavior (install = true).

When install = false: Dependency is resolved and content made available in template context, but file is not written to disk.

When install = true (or None): Dependency is installed as a file.

Returns

• Some(false) - Do not install the file, only make content available
• Some(true) - Install the file normally
• None - Use default behavior (install = true)

pub fn get_template_vars(&self) -> Option<&Value>

Get the template variable overrides for this resource.

Returns the resource-specific template variables that override the global [project] configuration. These variables are used when:

• Rendering the resource file itself
• Resolving the resource’s transitive dependencies

This allows creating specialized variants of generic resources without duplication.

Examples

use agpm_cli::manifest::{ResourceDependency, DetailedDependency};
use serde_json::json;

// Resource with template variable overrides
let resource = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: Some("community".to_string()),
    path: "agents/backend-engineer.md".to_string(),
    version: Some("v1.0.0".to_string()),
    branch: None,
    rev: None,
    command: None,
    args: None,
    target: None,
    filename: Some("backend-engineer-golang.md".to_string()),
    dependencies: None,
    tool: Some("claude-code".to_string()),
    flatten: None,
    install: None,
    template_vars: Some(json!({ "project": { "language": "golang" } })),
}));

assert!(resource.get_template_vars().is_some());

pub fn get_path(&self) -> &str

Get the path to the resource file.

Returns the path component of the dependency, which is interpreted differently based on whether this is a local or remote dependency:

• Local dependencies: Filesystem path relative to the manifest directory
• Remote dependencies: Path within the Git repository

Examples

use agpm_cli::manifest::{ResourceDependency, DetailedDependency};

// Local dependency - filesystem path
let local = ResourceDependency::Simple("../shared/helper.md".to_string());
assert_eq!(local.get_path(), "../shared/helper.md");

// Remote dependency - repository path
let remote = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: Some("official".to_string()),
    path: "agents/code-reviewer.md".to_string(),
    version: Some("v1.0.0".to_string()),
    branch: None,
    rev: None,
    command: None,
    args: None,
    target: None,
    filename: None,
    dependencies: None,
    tool: Some("claude-code".to_string()),
    flatten: None,
    install: None,
    template_vars: Some(serde_json::Value::Object(serde_json::Map::new())),
}));
assert_eq!(remote.get_path(), "agents/code-reviewer.md");

Path Resolution

The returned path should be processed appropriately based on the dependency type:

• Local paths may need resolution against the manifest directory
• Remote paths are used directly within the cloned repository
• All paths should use forward slashes (/) for cross-platform compatibility

pub fn is_pattern(&self) -> bool

Check if this is a pattern-based dependency.

Returns true if this dependency uses a glob pattern to match multiple resources, false if it specifies a single resource path.

Patterns are detected by the presence of glob characters (*, ?, [) in the path field.

pub fn get_version(&self) -> Option<&str>

Get the version constraint for dependency resolution.

Returns the version constraint that should be used when resolving this dependency from a Git repository. For local dependencies, always returns None.

Priority Rules

If both version and git fields are present in a detailed dependency, the git field takes precedence:

use agpm_cli::manifest::{ResourceDependency, DetailedDependency};

let dep = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: Some("repo".to_string()),
    path: "file.md".to_string(),
    version: Some("v1.0.0".to_string()),  // This is ignored
    branch: Some("develop".to_string()),   // This takes precedence over version
    rev: None,
    command: None,
    args: None,
    target: None,
    filename: None,
    dependencies: None,
    tool: Some("claude-code".to_string()),
    flatten: None,
    install: None,
    template_vars: Some(serde_json::Value::Object(serde_json::Map::new())),
}));

assert_eq!(dep.get_version(), Some("develop"));

Examples

use agpm_cli::manifest::{ResourceDependency, DetailedDependency};

// Local dependency - no version
let local = ResourceDependency::Simple("../local/file.md".to_string());
assert!(local.get_version().is_none());

// Remote dependency with version
let versioned = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: Some("repo".to_string()),
    path: "file.md".to_string(),
    version: Some("v1.0.0".to_string()),
    branch: None,
    rev: None,
    command: None,
    args: None,
    target: None,
    filename: None,
    dependencies: None,
    tool: Some("claude-code".to_string()),
    flatten: None,
    install: None,
    template_vars: Some(serde_json::Value::Object(serde_json::Map::new())),
}));
assert_eq!(versioned.get_version(), Some("v1.0.0"));

// Remote dependency with branch reference
let branch_ref = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: Some("repo".to_string()),
    path: "file.md".to_string(),
    version: None,
    branch: Some("main".to_string()),
    rev: None,
    command: None,
    args: None,
    target: None,
    filename: None,
    dependencies: None,
    tool: Some("claude-code".to_string()),
    flatten: None,
    install: None,
    template_vars: Some(serde_json::Value::Object(serde_json::Map::new())),
}));
assert_eq!(branch_ref.get_version(), Some("main"));

Version Formats

Supported version constraint formats include:

• Semantic versions: "v1.0.0", "1.2.3"
• Semantic version ranges: "^1.0.0", "~2.1.0"
• Branch names: "main", "develop", "latest", "feature/new"
• Git tags: "release-2023", "stable"
• Commit SHAs: "a1b2c3d4e5f6..."

pub fn is_local(&self) -> bool

Check if this is a local filesystem dependency.

Returns true if this dependency refers to a local file (no Git source), or false if it’s a remote dependency that will be resolved from a Git repository.

This is a convenience method equivalent to self.get_source().is_none().

Examples

use agpm_cli::manifest::{ResourceDependency, DetailedDependency};

// Local dependency
let local = ResourceDependency::Simple("../local/file.md".to_string());
assert!(local.is_local());

// Remote dependency
let remote = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: Some("official".to_string()),
    path: "agents/tool.md".to_string(),
    version: Some("v1.0.0".to_string()),
    branch: None,
    rev: None,
    command: None,
    args: None,
    target: None,
    filename: None,
    dependencies: None,
    tool: Some("claude-code".to_string()),
    flatten: None,
    install: None,
    template_vars: Some(serde_json::Value::Object(serde_json::Map::new())),
}));
assert!(!remote.is_local());

// Local detailed dependency (no source specified)
let local_detailed = ResourceDependency::Detailed(Box::new(DetailedDependency {
    source: None,
    path: "../shared/tool.md".to_string(),
    version: None,
    branch: None,
    rev: None,
    command: None,
    args: None,
    target: None,
    filename: None,
    dependencies: None,
    tool: Some("claude-code".to_string()),
    flatten: None,
    install: None,
    template_vars: Some(serde_json::Value::Object(serde_json::Map::new())),
}));
assert!(local_detailed.is_local());

Use Cases

This method is useful for:

• Choosing between filesystem and Git resolution strategies
• Validation logic (local deps can’t have versions)
• Installation planning (local deps don’t need caching)
• Progress reporting (different steps for local vs remote)
