Modules

sikits.textcraft

File	Class / Function	Description
string_nameing.py	CaseUtils	Convert strings between 11 naming conventions (snake_case, camelCase, PascalCase, kebab-case …). Handles full-width (全角) characters and Japanese punctuation.
string_nameing.py	CaseUtils.to_branch_name	Convert a GitHub issue title to a valid git branch name. Strips illegal chars, normalizes separators, supports Japanese input.
class_str.py	class_str	Recursive pretty-printer for plain Python objects — used by generated settings classes.

sikits.serialization

File	Class	Description
base.py	JsonMixin	@dataclass mixin that adds load_dict, load_file, save_file, to_json_string. Supports nested JsonMixin, Enum, Optional[T], list[JsonMixin].
setting.py	SettingRegister	Reads a TOML / YAML / JSON config file and generates a fully-typed Python class. The generated class loads from the config file at runtime — no values are baked in.

Settings workflow:

from pathlib import Path
from sikits.serialization.setting import SettingRegister

# Generate once (during development / CI)
SettingRegister(Path("config/settings.toml")).to_class_file(Path("src/myapp/settings.py"))

# Use everywhere — dynamically loaded at startup
from myapp.settings import Setting

print(Setting.db.host)
print(Setting.servers[0].name)

sikits.wbs

Work Breakdown Structure toolkit. Reads/writes project task data (CSV, JSON, Excel) and computes dashboard metrics (burndown, assignee load, review lag, status funnel).

sikits.json_diff

JSON diff engine with pluggable key-detection and output strategies. Produces structured diff results exportable as JSON or Markdown.

sikits.decotextual

Decorator utilities for contextual text processing pipelines.

sikits.database

Database modeling toolkit for PostgreSQL and Oracle.

File	Class / Function	Description
model/schema.py	Table, Column, Index	Unified Pydantic Dataclass models for database objects. Compatible with JsonMixin.
handler.py	TableHandler	Converts between DDL (Postgres/Oracle) and internal models. Supports multi-statement DDL and index extraction.
