Git Shallow Clones

Saving disk space and speeding up git-clone with shallow clones.

git clone --depth=1 --branch feature/hugo git@github.hugo OUTPUT_DIR

The shallow clone can be converted to a "full clone" by: git fetch --unshallow

Diff-Viewer with Position-Highlighting

When using git diff or git show the diff viewer shows only which lines have changed, but does not highlight the position of the change within the line. This is better with the diff-so-fancy viewer. It can be installed like this:

$ sudo snap install diff-so-fancy
$ git config --global core.pager "diff-so-fancy | less --tabs=4 -RFX"

If you want to return to the original diff viewer, perform these commands:

$ git config --global --unset core.pager
$ sudo snap remove diff-so-fancy

When redirecting the output to a file, the content will be in patch format.

Diff-Viewer with Side-by-Side

$ cargo install --locked difftastic
$ export PATH="$PATH:$(pwd)/.cargo/bin"
$ GIT_EXTERNAL_DIFF=difft git diff

Git Aliases

Showing graph (list graph = lg) on command line:

git config --global alias.lg \
    "log --graph --pretty=tformat:'%Cred%h%Creset -%C(auto)%d%Creset %s %Cgreen(%an %ar)%Creset'"

Cleaning Repository

Removing all changes and untracked files:

$ git checkout .
$ git clean -fd
