# Hello and welcome to the Alchemists Screencasts!
# Today, we'll look at using Exa (https://the.exa.website).

# Exa is a powerful enhancement to native `ls` functionality.
# Due to being implemented in Rust (https://www.rust-lang.org), it's fast too.
# For those on macOS, you can install via Homebrew (https://brew.sh):

brew install exa

# For comparison, here is native `ls` versus `exa` functionality:

ls
exa

# At first glance, the difference is subtle but you can see Exa is more concise.
# We can expand upon the above by comparing/contrasting a list view:

ls -alhT
exa --all --long

# Colorization is an immediate visible differentiator over `ls`.
# The succinctness of output -- without losing detail -- is another bonus.
# Here's what I like to use:

exa --all \
    --long \
    --header \
    --group \
    --group-directories-first \
    --time-style long-iso \
    --git \
    --git-ignore

# That's a lot to type so I have the above aliased:

cype x

# Now we only need to type `x` for the same result 🎉:

x

# Here's the breakdown of options used:
# `--all`                     - Show hidden and dot files.
# `--long`                    - Displays file metadata as a table.
# `--header`                  - Adds column headers.
# `--group`                   - Shows file's group.
# `--group-directories-first` - Lists directories before other files.
# `--time-style long-iso`     - Uses long ISO date/time stamps.
# `--git`                     - Shows Git status for file.
# `--git-ignore`              - Ignores files listed `.gitignore`.

# Use of `--git` needs more illustration, so I'll make some file changes:

printf "%s\n" "This is a test." > README.md
printf "%s\n" "This is a test." > LICENSE.md
git add LICENSE.md
touch test.txt
x

# First, notice `N` (new) next to `text.txt` since the file is new to Git.
# Second, notice `-M` (modified) next to `README.md` since the file is modified.
# Third, notice `M-` (staged) next to `LICENSE.md` since the file is staged.
# For further Git details, see: https://the.exa.website/features/git.

# Much like `ls`, Exa supports a one line view too:

ls -A1
exa --oneline --all --group-directories-first

# I like to alias the above as `x1`:

cype x1

# Finally, Exa has native tree support which I quite enjoy:

exa --tree

# I like to use the `xt` for this:

cype xt

# During this screencast, you might have noticed I use custom colors.
# To configure colors, Exa supports global constants which I define in `$HOME/.bashrc`:

export EXA_COLORS="da=1;34:di=32:gm=33:gd=31"

# For details on Exa's color keys and values, see: https://the.exa.website/docs/colour-themes.
# Finally, I recommend strict mode to prevent incompatible command line options:

export EXA_STRICT=true

# For more Exa features, see: https://the.exa.website/features.
