korname-generator 1.0.0

Dependency-free Korean name generator library and CLI extracted from Onnuri seed tooling

korname-generator

Dependency-free Korean name generator library and CLI.

It generates Korean names with both romanized and Hangul forms, supports seeded repeatable output, allows male/female/gender-neutral name pools, and can be customized with a config.yaml file.

Requirements

• Python 3.10+
• No runtime dependencies

Installation

From PyPI

python -m pip install korname-generator

The PyPI distribution is korname-generator; the installed console command is korean-name-generator.

From this repository, editable development install

Use this when you are working on the package locally:

git clone <repo-url>
cd korean-name-generator
python -m venv .venv
. .venv/bin/activate
python -m pip install -e .

From this repository, normal local install

Use this when you just want the CLI and importable package from the local checkout:

cd korean-name-generator
python -m pip install .

Build and install a wheel

python -m pip wheel . --no-deps -w dist
python -m pip install dist/korname_generator-0.1.0-py3-none-any.whl

After installation, the console command is available as:

korean-name-generator --help

You can also run it without installing by setting PYTHONPATH from the repo root:

PYTHONPATH=src python -m korean_name_generator --help

CLI examples

Generate five names:

korean-name-generator --count 5

Generate deterministic output with a seed:

korean-name-generator --count 5 --seed 7

Select a given-name pool:

korean-name-generator --count 3 --gender male
korean-name-generator --count 3 --gender female
korean-name-generator --count 3 --gender neutral

Use Korean-order display in plain output:

korean-name-generator --count 3 --order korean

Emit JSON:

korean-name-generator --count 2 --seed 1 --format json

Example JSON shape:

[
  {
    "family_name_en": "Lim",
    "family_name_ko": "임",
    "given_name_en": "Seseo",
    "given_name_ko": "세서",
    "gender": "female",
    "romanized": "Seseo Lim",
    "hangul": "임세서"
  }
]

Emit CSV:

korean-name-generator --count 10 --format csv > names.csv

Use an explicit config file:

korean-name-generator --count 3 --gender neutral --config ./config.yaml

Python API examples

Generate one name:

from korean_name_generator import generate_name

name = generate_name(gender="female", random_seed=7)
print(name.romanized)  # Western order, e.g. "Seseo Lim"
print(name.hangul)     # Korean order, e.g. "임세서"

Generate many names:

from korean_name_generator import generate_names

names = generate_names(10, gender="male", random_seed=42)
for name in names:
    print(name.display())

Reuse a generator so the random state advances between calls:

from korean_name_generator import KoreanNameGenerator

generator = KoreanNameGenerator(random_seed=7)
print(generator.generate(gender="neutral"))
print(generator.generate(gender="neutral"))

Load a custom config:

from korean_name_generator import KoreanNameGenerator

generator = KoreanNameGenerator.from_config("config.yaml", random_seed=7)
name = generator.generate(gender="female")
print(name.as_dict())

Configuration

The packaged defaults live in src/korean_name_generator/config.yaml. Runtime config resolution is:

1. explicit --config / config_path
2. $KOREAN_NAME_GENERATOR_CONFIG
3. local ./config.yaml
4. packaged defaults

Config files use this shape:

name_pools:
  family_names:
    - { en: Kim, ko: 김 }
  first_syllables:
    - { en: Ji, ko: 지 }
  male_second_syllables:
    - { en: Ho, ko: 호 }
  female_second_syllables:
    - { en: Na, ko: 나 }
  gender_neutral_second_syllables:
    - { en: Sol, ko: 솔 }

The parser is intentionally small and dependency-free. It supports the package's YAML shape shown above and JSON-compatible YAML. Each pool must be non-empty and each entry must include non-empty en and ko values.

The generator filters out repeated given-name syllables such as 지지. If a custom second-syllable pool cannot provide a non-repeating option for the chosen first syllable, generation raises ValueError.

Output fields

KoreanName.as_dict() and structured CLI output include:

Field	Meaning
family_name_en	Romanized family name
family_name_ko	Hangul family name
given_name_en	Romanized two-syllable given name
given_name_ko	Hangul two-syllable given name
gender	Selected pool: female, male, or neutral
romanized	Western-order display name
hangul	Korean-order Hangul display name

Development and verification

PYTHONPATH=src python -m unittest discover -s tests
python -m compileall -q src tests
PYTHONPATH=src python -m korean_name_generator --count 2 --seed 1 --format json
python -m pip wheel . --no-deps -w dist

Or use the Makefile shortcuts:

make lint
make test
make check

Release automation

Merges to main or dev run the GitHub Actions workflow in .github/workflows/release.yml. The workflow first runs make check (Ruff linting, Ruff format checks, Ty type checking, and pytest). If semantic-release creates a release, the publish job builds the source distribution and wheel with uv build, then publishes the korname-generator distribution to PyPI.

Publishing uses PyPI Trusted Publishing, so no long-lived PyPI API token is required. The PyPI project trusted publisher is configured with:

• owner: sagebynature
• repository: korean-name-generator
• workflow: release.yml
• environment: pypi

Semantic-release owns [project].version in pyproject.toml; use Conventional Commits on main for stable releases and on dev for rc prereleases.
