# ndf-parse 패키지

## 매 한 줄
> **"매 Eugen Systems 의 NDF (Niche Definition Files) format 의 Python parser/serializer"**. 매 Wargame: Red Dragon, Steel Division, WARNO 의 mod 작성에 사용. 매 lossless round-trip + AST manipulation 을 제공.

## 매 핵심

### 매 NDF format 이란
- Eugen 의 game data 정의 언어 — 매 unit stats, weapon, sound, UI binding 의 declarative description.
- Lua-like syntax + GUID reference + template instantiation. 매 plain text but very large (수만 lines).

### 매 ndf-parse 가 해주는 것
- **Parse**: NDF text → Python AST (List / Object / Map / Reference / Template node).
- **Walk**: tree traversal + by-name lookup.
- **Mutate**: in-place edit, insert, delete.
- **Serialize**: AST → NDF text, 매 formatting 의 보존 (whitespace, comments).

### 매 응용
1. WARNO / Steel Division mod 의 unit balancing.
2. Bulk find-replace (e.g. all small-arms 의 damage +10%).
3. Mod merge tool — 매 multiple mod 의 conflict-free combination.
4. CI validation — 매 NDF schema 의 lint.

## 💻 패턴

### Install + 매 first parse
```python
# pip install ndf-parse
import ndf_parse as ndf

with open("GameData/Generated/Gameplay/Gfx/UniteDescriptor.ndf", "r", encoding="utf-8") as f:
    source = ndf.load(f)  # returns ndf.model.List
print(type(source), len(source))
```

### 매 unit lookup by name
```python
unit = source.by_name("Descriptor_Unit_M1A2_Abrams_US").value
# unit is an Object node
```

### 매 module 안의 specific value 변경
```python
modules = unit.by_name("ModulesDescriptors").value
for module in modules:
    if module.value.type == "TBaseDamageModuleDescriptor":
        hp_row = module.value.by_name("MaxPhysicalDamages")
        hp_row.value = "12"  # was "10"
        break
```

### 매 weapon damage 의 bulk +10%
```python
def bump_damage(node):
    for member in node:
        if member.member == "PhysicalDamages":
            try:
                old = float(member.value)
                member.value = f"{old * 1.10:.2f}"
            except ValueError:
                pass
        if hasattr(member.value, "__iter__"):
            bump_damage(member.value)

bump_damage(source)
```

### 매 serialize back
```python
with open("Mod/UniteDescriptor.ndf", "w", encoding="utf-8") as f:
    ndf.write(source, f)
# 매 round-trip: comments / whitespace 의 가능한 한 보존
```

### 매 새 unit 의 clone + rename
```python
import copy
template = source.by_name("Descriptor_Unit_M1A2_Abrams_US")
clone = copy.deepcopy(template)
clone.name = "Descriptor_Unit_M1A3_Abrams_Custom"
source.add(clone)
```

### CLI mod build pipeline
```python
# build_mod.py
from pathlib import Path
import ndf_parse as ndf

for src_path in Path("GameData").rglob("*.ndf"):
    with src_path.open(encoding="utf-8") as f:
        tree = ndf.load(f)
    apply_patches(tree, src_path.name)
    out = Path("Mod") / src_path.relative_to("GameData")
    out.parent.mkdir(parents=True, exist_ok=True)
    with out.open("w", encoding="utf-8") as f:
        ndf.write(tree, f)
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| 매 single field 변경 | by_name + value 직접 assign |
| 매 bulk pattern 변경 | recursive walker function |
| 매 새 unit 추가 | deepcopy + rename + add |
| 매 cross-file reference | 매 파일별 parse + cross-link by GUID |
| 매 schema validation | custom walker + assertion |

**기본값**: 매 ndf-parse + Python script + git for version control. 매 manual NDF text edit 의 X.

## 🔗 Graph
- 응용: [[WARNO Modding]]

## 🤖 LLM 활용
**언제**: NDF mod 작성 + LLM 의 patch generation, schema 추론, balance tweak suggestion.
**언제 X**: 매 binary game asset (DDS, BANK) — 매 NDF X.

## ❌ 안티패턴
- **매 raw regex 의 NDF edit**: 매 nested template 의 corruption 위험.
- **encoding 누락**: NDF 는 UTF-8 (BOM 가능) — 매 default open() 의 fail.
- **매 reference name 의 typo**: silent — 매 by_name() 의 None return.

## 🧪 검증 / 중복
- Verified (ndf-parse PyPI docs, Eugen modding wiki 2024).
- 신뢰도 B (community-maintained).
