SAD!

Space Age seD

What does it do?

Basically sad is a Batch File Edit tool.

It will show you a really nice diff of proposed changes before you commit them.

Unlike sed, you can double check before you fat finger your edit.

Preview (with fzf)

Selectively replace std -> joseph joestar in the sad repo.

You can pick and choose which changes to apply.

You can also choose the clustering factor for changes using --unified=<n>. (Same as in GNU diff)

Preview (no fzf)

Replace all'"(\d+)"' -> '🌈$1🌈' in the chromium repo.

use --commit or -k to commit changes all at once.

-c is taken because sad has to trick fzf into thinking it's bash :)

How to use sad?

with fzf

export GIT_PAGER='<highlighter-of-your-choice>'
# ^ can be done in your bash/zsh/rc file.
find "$FIND_ARGS" | sad '<pattern>' '<replacement>'

without fzf

find "$FIND_ARGS" | sad '<pattern>' '<replacement>' | highlighter-of-your-choice

or

find "$FIND_ARGS" | sad '<pattern>' '<replacement>' --pager=<highlighter-of-your-choice>

or

export GIT_PAGER='<highlighter-of-your-choice>'
find "$FIND_ARGS" | sad '<pattern>' '<replacement>'

gotta go fast

If you wanna go fast.

• preview to verify you really want the changes.

• run with --commit, and redirect stdout to a file or /dev/null

Requirements

Technically none of these are "required", but they make sad so much happier.

If you install the things below, sad will automatically use them. It's progressive enhancement!

Commandline fuzzer

fzf

sad does not come with a UI, it uses fzf to perform selection.

Diff Colorizer

Any git compatible colourizer would work. I perfer these two:

delta

fd <files> | sad <pattern> <replacement> | delta

diff-so-fancy

fd <files> | sad <pattern> <replacement> | diff-so-fancy | less

Environmental Variables

Flags

Regex Flags

By default, sad uses smartcase, and multiline matching.

Compile from source:

Requirements:

To compile sad yourself you'll have to make sure you have Rust and cargo installed.

Install instructions:

To install cargo from source you can run the following commands:

cargo install --locked --all-features --path .

If you want to install it in a specific directory you can provide the --root flag, like so:

cargo install --locked --all-features --root="/usr/bin/" --path .

What about stdin -> stdout

If you just want to edit the shell stream, I would recommand sd, it uses the same concept, but its more for in stream edits. sad was inspired by my initial useage of sd.

command1 | sd '<pattern>' '<replacement>' | command2

ripgrep with --replace also works

command1 | rg --passthru --replace '<replacement>' -- '<pattern>' | command2

Take note however, rg will exit 1, it it finds no matches.
