# handic-py — Python wrapper for the HanDic MeCab dictionary

![PyPI - Version](https://img.shields.io/pypi/v/handic)

👉 **HanDic (dictionary) repository**: https://github.com/okikirmui/handic

`handic` is a **Python helper package** that makes it easy to use **HanDic**, a MeCab dictionary for contemporary Korean, **from Python code**.

> ⚠️ Important distinction  
> - **HanDic** = the MeCab dictionary itself (linguistic resource)  
> - **handic (this package)** = a Python interface / utility layer for HanDic  
>  
> The dictionary is developed and published separately;  
> this package focuses on *Python usability*.

---

## What this package does (and does not)

### ✔ What `handic` provides
- Automatic access to the **HanDic MeCab dictionary**
- A **high-level Python API** for Korean morphological analysis
- Transparent handling of **Jamo-based input/output**
- Safe fallback behavior for **unknown words**
- Optional **Hanja (漢字) representation** using HanDic features

### ✘ What `handic` is *not*
- It is **not** the primary distribution point of HanDic itself
- It does **not** define the linguistic content of the dictionary

---

- The **linguistic design and dictionary entries** live in the HanDic repository
- This package bundles a released snapshot of the dictionary **only to enable Python use**
- Updates to dictionary content are driven by the HanDic project

---

## 🚀 Quick Start (Python)

### Installation

```bash
pip install handic mecab-python3 jamotools
```

### Minimal example

```python
import handic

text = "공기 진짜 좋다."

print(handic.tokenize_hangul(text))
print(handic.pos_tag(text))
print(handic.convert_text_to_hanja_hangul(text))
```

**Example output**
```
['공기06', '진짜', '좋다01', '다06', '.']
[('공기06', 'NNG'), ('진짜', 'MAG'), ('좋다01', 'VA'), ('다06', 'EF'), ('.', 'SF')]
空氣 眞짜 좋다.
```

---

## High-level API (Python convenience layer)

### `tokenize_hangul(text)`

Return a list of tokens in Hangul base form(Unified Hangul Code).

- Internally uses HanDic via MeCab
- Automatically restores Hangul syllables from Jamo
- Robust against unknown words

If you want to obtain tokens in surface form instead of base form, specify “surface” for the `mode` option.

example:

```python
text = "얼굴이 좋아 보여요."

handic.tokenize_hangul(text, mode="surface")
# ['얼굴', '이', '좋아', '보여', '요', '.']

handic.tokenize_hangul(text)
# ['얼굴01', '이25', '좋다01', '보이다02', '요81', '.']
```

---

### `tokenize(text)`

Return tokens in **Jamo surface form**.

- Low-level wrapper around MeCab

```python
text = "집에나 갈까?"

handic.tokenize(text)
# ['집', '에', '나', '가', 'ᆯ까', '?']
```

---

### `pos(text)` — lightweight POS

Return `(surface, coarse_pos)` pairs.

- Surface is returned in **Jamo surface form**
- POS corresponds to the first feature field

---

### `pos_tag(text)`
Return a list of `(token, POS)` tuples.

- Uses HanDic base forms(Unified Hangul Code) when available
- Falls back to surface forms for unknown words
- POS tags are based on the Sejong tag set(see https://docs.komoran.kr/firststep/postypes.html)

The following is an example for comparing `pos()` and `pos_tag()`.

```python
text = "집에서 놀았습니다."

handic.pos(text)
# [('집', 'Noun'), ('에서', 'Ending'), ('놀아', 'Verb'), ('ᆻ', 'Prefinal'), ('습니다', 'Ending'), ('.', 'Symbol')]

handic.pos_tag(text)
# [('집01', 'NNG'), ('에서02', 'JKB'), ('놀다01', 'VV'), ('ㅆ', 'EP'), ('습니다', 'EF'), ('.', 'SF')]
```

---

### `parse(text)`

Return raw MeCab output string.

- Includes all feature fields
- Intended for advanced use

```python
print(handic.parse("어디서 노나요?"))
```

output:

```
어디   Noun,代名詞,*,*,*,어디01,어디,*,*,A,NP
서    Ending,助詞,処格,*,*,서15,서,*,"에서02의 준말",*,JKB
노    Verb,自立,ㄹ語幹-脱落形,語基1,*,놀다01,노,*,*,A,VV
나요   Ending,語尾,終止形,*,1接続,나요,나요,*,"-나11",*,EF
?     Symbol,疑問符,*,*,*,?,?,*,*,*,SF
EOS
```

---

### `convert_text_to_hanja_hangul(text)`
Convert text into **mixed Hanja + Hangul** representation.

- Uses HanDic feature field (index 7)
- Preserves whitespace and punctuation
- Converts remaining Jamo into complete Hangul syllables

> ⚠️ **Caution**  
> 
> It may be possible to misidentifying homonyms. e.g. 자신: 自信/自身

---

## Low-level access (for compatibility)

```python
import handic

print(handic.DICDIR)   # path to bundled HanDic snapshot
print(handic.VERSION)  # HanDic dictionary version
```

These are provided mainly for **backward compatibility** and inspection.

---

## Typical use cases

- Using HanDic conveniently from Python
- Korean corpus analysis and language education research
- Preprocessing Korean text for NLP pipelines
- Exploring Hangul / Hanja correspondences in contemporary Korean
