ndf-parse

매 한 줄

"매 Eugen Systems NDF (Nakami Design File) 의 lossless parser — 매 mod tooling 의 backbone.". NDF 는 매 Eugen 의 in-house declarative DSL — Wargame, Steel Division, WARNO 매 game data definition 사용. ndf-parse (Ulibos) 는 매 round-trip preservation (comments, whitespace, formatting) 의 Python parser.

매 핵심

매 NDF 구조

• Object: EntityName is TEntityType ( property = value ) — 매 typed object literal.
• Template: template TFoo [Param: int] is TFoo ( ... ) — 매 generic-like.
• Map: MAP[(k, v), ...] — 매 ordered dictionary.
• Vector: [a, b, c] — 매 ordered list.
• GUID/Reference: GUID:{...}, ~/Path/To/Object — 매 reference.

매 ndf-parse 특징

• AST round-trip: 매 parse → modify → unparse 후 매 byte-identical (modify X 영역).
• Visitor / walker: 매 dataclass-like node tree.
• CLI: ndf command — 매 batch script.
• 2026 stable: WARNO modding scene 매 standard.

매 응용

1. WARNO mod (unit balance, new factions).
2. Steel Division 2 mod.
3. Automated balance tuning (CSV → NDF script).
4. Diff tool — 매 patch-vs-vanilla compare.

💻 패턴

Install + parse

# pip install ndf-parse
import ndf_parse as ndf

with open('UniteDescriptor.ndf', 'r', encoding='utf-8') as f:
    source = f.read()

tree = ndf.parse(source)  # ndf.model.List
print(len(tree))  # top-level statement count

Walk + find object

for stmt in tree:
    if stmt.kind == 'object' and stmt.name == 'Descriptor_Unit_M1A2_Abrams_US':
        unit = stmt.value
        for member in unit:
            if member.member == 'MaxPhysicalDamages':
                print('HP:', member.value)

Mutate + write back

import ndf_parse as ndf
from ndf_parse import edit

with edit('UniteDescriptor.ndf') as tree:
    for stmt in tree:
        if stmt.kind == 'object' and 'Abrams' in stmt.name:
            for m in stmt.value:
                if m.member == 'MaxPhysicalDamages':
                    m.value = '15'  # buff HP

# `with edit(...)` 매 auto-write back, 매 untouched bytes 보존.

Add new member

from ndf_parse.model import MemberRow

with edit('Ammunition.ndf') as tree:
    for stmt in tree:
        if stmt.name == 'Ammo_Custom_HEAT':
            stmt.value.add(MemberRow(member='HEDamage', value='9'))

Template instantiation lookup

def find_template(tree, name):
    for stmt in tree:
        if stmt.kind == 'template' and stmt.name == name:
            return stmt
    return None

CSV → NDF batch patch

import csv, ndf_parse as ndf
from ndf_parse import edit

balance = {row['unit']: row for row in csv.DictReader(open('balance.csv'))}

with edit('UniteDescriptor.ndf') as tree:
    for stmt in tree:
        if stmt.kind != 'object': continue
        cfg = balance.get(stmt.name)
        if not cfg: continue
        for m in stmt.value:
            if m.member in cfg:
                m.value = cfg[m.member]

Diff vs vanilla

import ndf_parse as ndf
vanilla = ndf.parse(open('vanilla/UniteDescriptor.ndf').read())
modded  = ndf.parse(open('mod/UniteDescriptor.ndf').read())

vanilla_units = {s.name: s for s in vanilla if s.kind == 'object'}
for s in modded:
    if s.kind != 'object': continue
    base = vanilla_units.get(s.name)
    if base and ndf.unparse(base.value) != ndf.unparse(s.value):
        print(f'changed: {s.name}')

매 결정 기준

상황	Approach
매 single value tweak	with edit() context manager
매 large refactor	parse → walk → unparse explicit
매 batch CSV-driven	edit + lookup table
매 lossless preservation 필요	ndf-parse (regex 의 X)
매 read-only analytics	parse + walk only

기본값: 매 with edit() context — 매 mod 작업 80% case.

🤖 LLM 활용

언제: 매 Eugen game mod, WARNO balance script, NDF diff/patch tool. 언제 X: 매 non-Eugen game (Bethesda Plugin = ESM/ESP, Paradox = PDX script). 매 다른 parser.

❌ 안티패턴

• Regex 으로 NDF 편집: 매 nested template / comment break. 매 ndf-parse 의 사용.
• 매 unparse 후 manual format: 매 round-trip 의 손실. 매 ndf-parse 가 매 formatting 보존.
• 매 GUID hard-code: 매 reference 깨짐. 매 path 의 사용 (~/Foo/Bar).

🧪 검증 / 중복

• Verified (ndf-parse PyPI, Ulibos GitHub, WARNO modding wiki).
• 신뢰도 A-.
