  • 한글 지원 안하는 폰트 사용하면 export 시 한글이 다 굴림으로 바뀜. 현재 Google docs에서 지원하는 한글 폰트 중 쓸만한 건 나눔 고딕 밖에 없음. Noto Sans KR 추가됨
    • fonts-nanum 패키지 설치했더라도 Google docs의 "Nanum Gothic"은 odp로 export 후 LibreOffice Impress에서 열 때 "font is not available and will be substituted"라고 나옴. 그런데 대부분 글자는 잘 표시됨 (fc-match "Nanum Gothic" 실행 시 NanumGothic.ttf 찾음). 그런데 Impress에서는 한글과 ascii char 간격이 훨씬 커서 여하간 레이아웃이 깨짐.

• Merging working tree and stash: git add, then stash pop. https://stackoverflow.com/a/16613814. Alternatively, git checkout instead of git stash apply https://stackoverflow.com/a/16625128.
• git pull --rebase --autostash

• git reflog
  • git log -g
• getting info from git log/diff
  • -M[<n>], --find-renames[=<n>], -C[<n>], --find-copies[=<n>] (+ -C -C, -C -C -C). Also applicable to git blame.
    • hack to force copy detection https://stackoverflow.com/a/46484848
  • -D, --irreversible-delete
  • log --follow a-single-file: history of a file, detecting rename and copy
  • patch search
    • -G pat: grep
    • -S pat [--pickaxe-regex]: change in number of occurrences

• git log -L
  • :{range}Gclog
• git apply --reject --whitespace=fix
• git files absolute dir git -C "$ROOT" ls-files | awk -v R="$ROOT" '{ print R "/" $0 }'
• git reset --merge <commit>: like --hard, but doesn't touch files with changes that are not added (diff between index and working tree)
  • Can be used for aborting stash pop when there was changes in working tree. https://stackoverflow.com/a/60444590
• git diff --check
• man gitrevisions(7)
  • range <rev>: commits reachable from <rev> (i.e. ancestors)
  • range ^<rev>: commits not reachable from <rev> (i.e. ancestors)
  • range ^main feature (= main..feature):

• what's the best practice for spliting a commit?
• git blame --reverse (fugitive_<CR> in blob with count) may not show the commit that deletes the line when the path includes merge commits. https://stackoverflow.com/a/42707940
• git range-diff
• Rebasing merge commit with conflict resolution and other additional changes (that modify the part of code that didn't produce conflict marker, but conceptually is a conflict). git rebase --rebase-merges origin/master + rerere doesn't seem to carry over the additional changes. Had to merge the merge commit.
  • This kind of merge is called "evil merge". Potential solution?: https://git-blame.blogspot.com/2015/10/fun-with-recreating-evil-merge.html
• shallow
  • shallow clone to branch

    git clone URL --depth 1 -b BRANCH
    

    Note that it works only for branches.
  • shallow fetch tag

    git fetch --depth 1 origin tag v1.1
    

    "tag" here is a keyword to indicate that the following is tag (see <refspec>).
  • shallow fetch new branch

    git remote set-branches --add origin <branch-name>
    git fetch --depth 1 origin <branch-name>
    

    all branches

    git remote set-branches origin '*'
    

  • shallow submodule

    git submodule update --init --recursive --depth=1
    

    Not perfect, but good enough.
  • deepening

    git fetch --deepen=N
