⚙️ Configuration Management

You can save frequently used options as default settings using Git-style configuration:

# List all settings
grit config --list
grit config -l

# Get specific setting
grit config core.lang
grit config core.model

# Set configuration (key value format)
grit config core.lang ko
grit config core.model gpt-4
grit config core.commit true
grit config core.split false
grit config core.prompt /path/to/custom-prompt.txt

# Remove setting
grit config --unset core.lang
grit config --unset core.model

# Global config (applies to all repositories)
grit config --global core.lang en
grit config --global core.model gpt-4
grit config --global --list

# Local repository config (default behavior, overrides global)
grit config --local --list
grit config --local core.lang ko

Available Configuration Sections

Core Section ([core])

Key	Valid Values	Description
core.lang	ko, ko-KR, en, en-US, en-GB, ja, ja-JP, zh, zh-CN, zh-TW	Default commit message language
core.model	gpt-5 (recommended), gpt-4o, gpt-4, gpt-3.5-turbo, gpt-4o-mini	Default AI model (⚠️ gpt-4o-mini may include markdown formatting)
core.commit	true, false	Automatically commit after generating message
core.split	true, false	Automatically split complex changes

Configuration is stored in INI format:

Global config (~/.grit/config):

[core]
lang = en
model = gpt-5  # Recommended default
commit = false

Local config (./grit/config):

[core]
lang = ko
commit = true
split = false
prompt = /path/to/custom-prompt.txt

로컬 설정이 글로벌 설정보다 우선순위를 가집니다.

🔧 Troubleshooting

GPT-4o-mini 모델 사용 시 출력 형식 문제

문제: GPT-4o-mini 모델 사용 시 커밋 메시지에 코드 블록 마크다운(```)이 포함되어 출력될 수 있습니다.

해결 방법:

# GPT-5 사용 (권장)
grit commit --model gpt-5

# 또는 기본 모델을 GPT-5로 변경
grit config core.model gpt-5

# 대안: GPT-4o, GPT-4 또는 GPT-3.5-turbo 사용
grit commit --model gpt-4o
grit commit --model gpt-4
grit commit --model gpt-3.5-turbo

참고: 이는 GPT-4o-mini 모델의 특성으로, 향후 업데이트에서 개선될 예정입니다.
