리눅스에서 문서화

리눅스에서 코드 문서화 작업하려는데, Playonlinux로 office2016 설치 시도하다가 포기하고 만든 차선책.

1) 온라인 파워포인트
https://office.live.com/start/PowerPoint.aspx
윈도우 버전처럼 그림의 배경색제거, 3D 회전같은 기능은 지원안됨.

2) https://pixlr.com/editor/
위 단점들 보완을 위해 사용.
create new iamge - transparent 투명 배경 선택
ㄴ 파워포인트에서 다른 이미지와 조합을 고려함.

새 layout  생성
컴퓨터에서 이미지 파일 열기 - wand(W) 또는 lasso (L) 툴로 오려내기
* wand 비활성화 : Marquee(Q) == 사각형 잘라내기 선택후 레이아웃 아무 자리 클릭.
배경제거 복사 붙여넣기. etc..
edit - free transform - 꼭지점 크기조정 / 꼭지점에서 offset 10  ~ 30? 픽셀 위치에서 rotation
edit - free distortion - 꼭지점 위치 옮겨서 3D 회전 연출.

steam / ubuntu

playonlinux 설치
* apt-get install은 구버전
* 홈페이지에서 최신 deb 파일 설치

playonlinux 실행해서,
tools - manage wine versions - 2.22-staging
* apt install wine 대신  이걸로 설치.

카카오톡
Configure 아이콘 - new - 32bit windows
- 2.22-staging - kakao (virtual drive 이름 지정)

virtual drive 선택 - install components 탭 -
(gdiplus /riched20 / riched30 / wmp9 )
다운로드중 에러발생시 될때가지 retry

Wine 탭 - wine configure - window 7 이상


AOE2 HD
install - aoe2hd - 스팀설치까지
Wine 탭 - wine configure - window xp
General 탭 - Arguments : -no-cef-sandbox
이상 steam black screen 버그 해결

그다음 게임 다운로드 버그는

코딩/네이밍 컨벤션 툴

내 경우 c++은 구글 스타일 가이드, python은 pep8을 따르려고 한다.
다만, 주로 작업하는 언어가 boost python을 이용한 python + c++ 혼합이라 naming convention이 서로 충돌하기 때문에 c++, python 모두 naming convention은 pep8-naming convention으로 통일.

* Python을 쓰기 전에는 함수는 lower camelCase, 클래스는 upper CamelCase를 사용했는데, 생각해보니 opencv naming convention  영향을 많이 받은듯.

아래는 컨벤션 체크에 사용하려고 알아본 프로그램.

# c++
1-1 cpplint
https://github.com/cpplint/cpplint
* 구글 스타일 체크.
* 단점 :  네이밍 컨벤션 체크는 지원안함.

1-2 cncc
* https://github.com/mapbox/cncc
* 굉장히 단순한 파이썬 코드+정규식 정의로 c++ 네이밍 컨벤션을 체크해줌.
* 정규식으로 style파일을 만들어 프로젝트에서 약속한 네이밍 컨벤션을 지정할 수 있음.
* cpplint를 보완해서 쓰면 좋음.

# python
2-1 flake8
* http://flake8.pycqa.org/en/latest/index.html#quickstart
* 코딩 컨벤션 / 네이밍 컨벤션 모두 체크해줌.

파이썬 라틴 유니코드

https://stackoverflow.com/questions/2247205/python-returning-the-wrong-length-of-string-when-using-special-characters

word = u'a\u0301'
unicodedata.normalize('NFC', word)
의 결과로
u'\xe1' # single character: á

를 얻을수 있고, 필요에 따라선 'NFD'로 그 역으로 변환 가능.

print(u'a\u0301')와 print(u'\xe1') 는 둘다 á 라고만 출력하지만, 정작 비교하면
u'a\u0301' == u'\xe1' 결과는 False가 되서 고통스러운 문제를 일으킨다.

다음 예시 참고.
