⚙️ Configuration

Configuration is defined in YAML format. The default location is wizard/codegen.yaml.

Complete Example

proto:
  # Git source configuration (used by default)
  source:
    git: "[e-mail]:YourOrg/proto-definitions.git"
    ref: "latest-tag"                # Default: auto-resolves to latest semver tag
    # fds: "build/descriptor.pb"     # Optional: use pre-built descriptor
    include_info: true               # Include source info in descriptors

  # Local path (used with --local flag for development)
  root: "../local-protos"

  # Cache directory for git clones
  cache_dir: ".cache/proto-common"

  # Include paths (relative to proto root)
  includes:
    - "{proto_root}/shared"
    - "{proto_root}/service/wizard"

  # File patterns to discover
  files:
    - "pages/**/*.proto"
    - "models/*.proto"

targets:
  typescript:
    templates: "wizard/templates/ts"
    out: "src/generated/ts"
    render:
      # Generate form components for *Form messages
      - template: "form.j2"
        for_each: "message"
        mode: "write-once"
        where:
          all:
            - name: "*Form"
          not:
            - file: "*/shared/design_system/*"
        output: "components/{{ item.name.kebab_case }}-form/index.tsx"

      # Generate context providers for *Context messages
      - template: "context.j2"
        for_each: "message"
        where:
          any:
            - name: "*Context"
          not:
            - file: "*/shared/design_system/*"
        output: "contexts/{{ item.name.kebab_case }}/index.tsx"

  swift:
    templates: "wizard/templates/swift"
    out: "ios/Generated"
    render:
      - template: "struct.j2"
        for_each: "message"
        output: "{{ item.name.pascal_case }}.swift"

  kotlin:
    templates: "wizard/templates/kotlin"
    out: "android/generated"
    render:
      - template: "data_class.j2"
        for_each: "message"
        output: "{{ item.name.pascal_case }}.kt"

hooks:
  root: "wizard"
  module: "hook_sample"   # Optional: custom filters module

Proto Configuration

Key	Type	Description
root	string	Local path to proto files (used with --local flag)
source.git	string	Git repository URL for proto source
source.ref	string	Git ref: tag, branch, commit SHA, or latest-tag (default: latest-tag)
source.fds	string	Path to pre-built FileDescriptorSet (optional)
source.include_info	bool	Include source info in protoc output (default: true)
cache_dir	string	Directory for caching git clones
includes	list[string]	Include paths for proto imports
files	list[string]	Glob patterns for proto file discovery

Special Ref: latest-tag

Use ref: "latest-tag" to automatically checkout the latest semver tag from the repository:

proto:
  source:
    git: "[e-mail]:YourOrg/proto-definitions.git"
    ref: "latest-tag"  # Automatically resolves to latest semver tag (e.g., v2.1.0)

This feature:

• Lists all tags in the repository
• Filters for valid semver tags (e.g., v1.2.3, 1.0.0, v2.0.0-beta)
• Prefers stable releases over prereleases (e.g., v1.0.0 > v1.0.0-beta)
• Checks out the highest version according to semver ordering

Proto Source Resolution

You can configure both a local path (proto.root) and a git source (proto.source) simultaneously. This allows developers to easily switch between tagged releases and local development:

Default behavior (no flags):

1. proto.source.git — clone/fetch from git repository
2. Falls back to proto.root — if no git source is configured
3. Error — if neither is available

With --local flag:

1. proto.root — use local filesystem path
2. Error — if proto.root is not configured or doesn't exist

This design enables a common workflow:

• CI/Production: Uses git source with latest-tag (the default ref)
• Local Development: Use --local flag to test against local proto changes

# Use git source (default - fetches latest tag)
wizard-codegen generate

# Use local protos for development
wizard-codegen --local generate

Targets Configuration

Each target represents a language/output configuration.

Key	Type	Description
templates	string	Path to Jinja2 template directory
out	string	Output directory for generated files
render	list	List of render rules

Render Rules

Key	Type	Description
template	string	Template filename (relative to templates dir)
output	string	Output path pattern (Jinja2 template string)
for_each	enum	Iteration mode: file, message, enum, service
mode	enum	Write mode: overwrite, append, write-once
where	object	Filter predicates (optional)

Write Modes

Mode	Description
overwrite	Always replace existing files (default)
append	Add content to end of existing files
write-once	Only create if file doesn't exist

Where Clauses (Filtering)

Filter which items to generate for:

where:
  all:          # AND conditions (all must match)
    - name: "*Form"
    - package: "wizard.*"
  any:          # OR conditions (at least one must match)
    - name: "*Context"
    - name: "*Provider"
  not:          # Exclude matching items
    - file: "*/design_system/*"
    - name: "*Internal"

Predicate Fields

Field	Description	Example
name	Message/enum/service name	"*Form", "User*", "Order"
package	Proto package name	"wizard.*", "com.example.*"
file	Proto file path	"*/shared/*", "user/*.proto"
full_name	Fully qualified name	".wizard.UserForm"
option.equals	Match proto options	{ key: "deprecated", value: true }

Patterns support:

• Glob patterns: *, ?, [abc]
• Regex patterns: Any valid Python regex

Hooks Configuration

Key	Type	Description
root	string	Root directory for hooks module (default: "wizard")
module	string	Python module name with register() function

📝 Template Authoring

Templates use Jinja2 syntax with custom extensions.

Template Context

When a template is rendered, it receives a rich context:

{
    "proto_root": "/path/to/protos",

    # Current item (when using for_each)
    "item": {
        "name": Name("UserForm"),          # Name object with case transformations
        "full_name": ".wizard.UserForm",
        "file": "user/user_form.proto",
        "package": "wizard",
        "fields": [...],                   # List of field objects
        "nested_messages": [...],          # Nested message definitions
        "nested_enums": [...],             # Nested enum definitions
    },

    # All files (for cross-referencing)
    "files": [...],

    # Indexes for quick lookup
    "message": { ".package.MessageName": {...}, ... },
    "enum": { ".package.EnumName": {...}, ... },
    "service": { ".package.ServiceName": {...}, ... },
    "types": { ".package.TypeName": {...}, ... },
}

File Object

    "name": Name("user_form.proto"),
    "basename": "user_form",
    "package": "wizard",
    "package_path": "wizard",
    "imports": ["common/timestamp.proto"],
    "messages": [...],
    "enums": [...],
    "services": [...],
    "options": <FileOptions>,
}

Message Object

{
    "name": Name("UserForm"),
    "full_name": ".wizard.UserForm",
    "file": "user/user_form.proto",
    "package": "wizard",
    "fields": [
        {
            "name": Name("user_name"),
            "number": 1,
            "label": 1,               # 1=optional, 2=required, 3=repeated
            "type": 9,                # Proto type number (9=string)
            "type_name": "",          # For message/enum refs: ".package.Type"
            "json_name": "userName",
            "field": <FieldDescriptor>,
        },
        ...
    ],
    "nested_messages": [...],
    "nested_enums": [...],
}

Enum Object

{
    "name": Name("Status"),
    "full_name": ".wizard.Status",
    "file": "common/status.proto",
    "package": "wizard",
    "enum_values": [
        {"name": "STATUS_UNKNOWN", "number": 0},
        {"name": "STATUS_ACTIVE", "number": 1},
        ...
    ],
}

Service Object

{
    "name": Name("UserService"),
    "file": "user/user_service.proto",
    "package": "wizard",
    "methods": [
        {
            "name": Name("GetUser"),

            "options": <MethodOptions>,
        },
        ...
    ],
}

Name Transformations

Every name in the context is wrapped in a Name object that provides automatic case transformations:

{{ item.name.raw }}              →  UserFormRequest
{{ item.name.snake_case }}       →  user_form_request
{{ item.name.kebab_case }}       →  user-form-request
{{ item.name.pascal_case }}      →  UserFormRequest
{{ item.name.camel_case }}       →  userFormRequest
{{ item.name.macro_case }}       →  USERFORMREQUEST
{{ item.name.macro_snake_case }} →  USER_FORM_REQUEST

Use in output paths:

output: "{{ item.name.kebab_case }}/index.tsx"
# Generates: user-form-request/index.tsx

Use in templates:

export interface {{ item.name.pascal_case }} {
{% for field in item.fields %}
  {{ field.name.camel_case }}: {{ field | ts_type }};
{% endfor %}
}

Built-in Filters

The following filters are available in all templates:

Common Filters

Filter	Description	Example
replace	String replacement	{{ name | replace("_", "-") }}

TypeScript Filters (via hooks)

Filter	Description	Example
ts_type	Proto to TS type	{{ field | ts_type }} → string, number, User
ts_type_optional	TS type with undefined	{{ field | ts_type_optional }} → string | undefined
is_ts_optional	Check if optional	{% if field | is_ts_optional %}?{% endif %}
is_repeated	Check if array	{% if field | is_repeated %}[]{% endif %}

Swift Filters (via hooks)

Filter	Description	Example
swift_type	Proto to Swift type	{{ field | swift_type }} → String, Int32, User
swift_default	Swift default value	{{ field | swift_default }} → "", 0, []

Kotlin Filters (via hooks)

Filter	Description	Example
kotlin_type	Proto to Kotlin type	{{ field | kotlin_type }} → String, Int, User
kotlin_default	Kotlin default value	{{ field | kotlin_default }} → "", 0, emptyList()

Go Filters (via hooks)

Filter	Description	Example
go_type	Proto to Go type	{{ field | go_type }} → string, int32, *User
go_zero	Go zero value	{{ field | go_zero }} → "", 0, nil

Template Example

// {{ item.name.pascal_case }}.swift
// Generated from: {{ item.file }}
// Package: {{ item.package }}

import Foundation

/// {{ item.name.pascal_case }} - Auto-generated from protobuf.
public struct {{ item.name.pascal_case }}: Codable, Equatable, Sendable {
{% for field in item.fields %}
    /// {{ field.name.raw }} - Proto type: {{ field.type }}
    public var {{ field.name.camel_case }}: {{ field | swift_type }}
{% endfor %}

    public init(
{% for field in item.fields %}
        {{ field.name.camel_case }}: {{ field | swift_type }} = {{ field | swift_default }}{% if not loop.last %},{% endif %}

    ) {
{% for field in item.fields %}
        self.{{ field.name.camel_case }} = {{ field.name.camel_case }}
{% endfor %}
    }
}

🔌 Custom Hooks

Extend wizard-codegen with custom Jinja2 filters and helpers.

Creating a Hooks Module

1. Create a Python file in your hooks root (default: wizard/):

# wizard/my_hooks.py

from jinja2 import Environment
from core import CodegenConfig

def custom_filter(value):
    """Your custom filter logic."""
    return str(value).upper()

def format_field_doc(field):
    """Generate documentation for a field."""
    return f"@param {field['name'].camel_case} - {field.get('json_name', '')}"

def register(env: Environment, *, target: str, config: CodegenConfig) -> None:
    """
    Register custom filters and globals.

    Args:
        env: Jinja2 environment to extend
        target: Current target name (e.g., "typescript", "swift")
        config: Full codegen configuration
    """
    # Register filters
    env.filters["uppercase"] = custom_filter
    env.filters["field_doc"] = format_field_doc

    # Register globals (optional)
    env.globals["TARGET"] = target

    # Target-specific filters
    if target == "typescript":
        env.filters["ts_custom"] = lambda x: f"TS_{x}"

2. Reference it in your configuration:

hooks:
  root: "wizard"
  module: "my_hooks"   # Loads wizard/my_hooks.py

3. Use in templates:

{{ item.name.raw | uppercase }}
{{ field | field_doc }}
Current target: {{ TARGET }}

Type Mapping Example

Here's a complete example of type mapping hooks:

# wizard/type_mappings.py

from jinja2 import Environment

# Proto type constants
TYPE_STRING = 9
TYPE_BOOL = 8
TYPE_INT32 = 5
TYPE_INT64 = 3

TS_TYPES = {
    TYPE_STRING: "string",
    TYPE_BOOL: "boolean",
    TYPE_INT32: "number",
    TYPE_INT64: "bigint",
}

SWIFT_TYPES = {
    TYPE_STRING: "String",
    TYPE_BOOL: "Bool",
    TYPE_INT32: "Int32",
    TYPE_INT64: "Int64",
}

def ts_type(field):
    if field.get("type_name"):
        return field["type_name"].split(".")[-1]
    return TS_TYPES.get(field.get("type"), "unknown")

def swift_type(field):
    if field.get("type_name"):
        return field["type_name"].split(".")[-1]
    return SWIFT_TYPES.get(field.get("type"), "Any")

def register(env: Environment, *, target: str, config) -> None:
    if target == "typescript":
        env.filters["lang_type"] = ts_type
    elif target == "swift":
        env.filters["lang_type"] = swift_type

Adding New Target Languages

1. Create templates in wizard/templates/<language>/:

{# wizard/templates/rust/struct.j2 #}
// {{ item.name.pascal_case }}.rs

#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct {{ item.name.pascal_case }} {
{% for field in item.fields %}
    pub {{ field.name.snake_case }}: {{ field | rust_type }},
{% endfor %}
}

2. Add type mapping hooks (optional):

# wizard/rust_hooks.py

RUST_TYPES = {
    9: "String",
    8: "bool",
    5: "i32",
    3: "i64",
}

def rust_type(field):
    if field.get("type_name"):
        return field["type_name"].split(".")[-1]
    return RUST_TYPES.get(field.get("type"), "Unknown")

def register(env, *, target, config):
    if target == "rust":
        env.filters["rust_type"] = rust_type

3. Add target configuration:

targets:
  rust:
    templates: "wizard/templates/rust"
    out: "src/generated"
    render:
      - template: "struct.j2"
        for_each: "message"
        output: "{{ item.name.snake_case }}.rs"

📚 Examples

TypeScript React Form Component

{# templates/ts/form.j2 #}
import React, { useState } from 'react';

export interface {{ item.name.pascal_case }}Data {
{% for field in item.fields %}
  {{ field.name.camel_case }}{% if field | is_ts_optional %}?{% endif %}: {{ field | ts_type }};
{% endfor %}
}

export const {{ item.name.pascal_case }}: React.FC = () => {
{% for field in item.fields %}
  const [{{ field.name.camel_case }}, set{{ field.name.pascal_case }}] = useState<{{ field | ts_type }}>();
{% endfor %}

  return (
    <form>
{% for field in item.fields %}
      <input
        name="{{ field.name.snake_case }}"
        value={ {{ field.name.camel_case }} ?? ''}
        onChange={(e) => set{{ field.name.pascal_case }}(e.target.value)}
      />
{% endfor %}
    </form>
  );
};

Kotlin Data Class

{# templates/kotlin/data_class.j2 #}
package {{ item.package }}

import kotlinx.serialization.Serializable

@Serializable
data class {{ item.name.pascal_case }}(
{% for field in item.fields %}
    val {{ field.name.camel_case }}: {{ field | kotlin_type }} = {{ field | kotlin_default }}{% if not loop.last %},{% endif %}
{% endfor %}
)

Go Struct with JSON Tags

{# templates/go/struct.j2 #}
package {{ item.package | replace(".", "_") }}

// {{ item.name.pascal_case }} - Generated from {{ item.file }}
type {{ item.name.pascal_case }} struct {
{% for field in item.fields %}
	{{ field.name.pascal_case }} {{ field | go_type }} {{ field | go_json_tag }}
{% endfor %}
}

🔧 Troubleshooting

Common Issues

"protoc is not available in PATH"

# macOS
brew install protobuf

# Ubuntu/Debian
apt install -y protobuf-compiler

# Verify installation
protoc --version

"Config error: proto.root not found"

Either specify a local proto.root or configure proto.source.git:

proto:
  root: "../my-protos"  # Local path
  # OR
  source:
    git: "[e-mail]:Org/protos.git"
    ref: "main"

"Failed to import hooks module"

Ensure your hooks module:

1. Is in the correct directory (hooks.root config)
2. Has a register(env, *, target, config) function
3. Has no import errors

# Test manually
uv run python -c "import wizard.my_hooks"

"Template variable undefined"

• Use --verbose to inspect the context
• Check your for_each setting matches the expected context
• Verify field names in the proto file
