FYI

FYI is a simple CLI tool for x86-64 Linux machines that prints an arbitrary status-style message, optionally indented, timestamped, and/or prefixed. You know, stuff like:

• Error: Something broke!
• Warning: I can't keep doing this!
• Success: Life is good!

(Github doesn't display colored text, but just imagine the error prefix in , the success in , etc.)

That's it!

Why?

The main idea is to make it easier to communicate successes and errors from within shell scripts, particularly in regards to color. ANSI formatting isn't difficult, but all that extra code is difficult to read.

Take for example:

# The manual way.
echo "\033[1;91mError:\033[0m Something broke!"

# Using FYI:
fyi error "Something broke!"

Installation

Debian and Ubuntu users can just grab the pre-built .deb package from the latest release.

This application is written in Rust and can alternatively be built from source using Cargo:

# Clone the source.
git clone https://github.com/Blobfolio/fyi.git

# Go to it.
cd fyi

# Build as usual. Specify additional flags as desired.
cargo build \
    --bin fyi \
    --release

(This should work under other 64-bit Unix environments too, like MacOS.)

Usage

The primary usage is to generate a message with one of the default prefixes, like: fyi <PREFIX> [flags] [options] <MSG>, where the prefix is one of:

• crunched
• debug
• done
• error
• info
• notice
• success
• task
• warning

The following flags and options are available.

Short	Long	Value	Description	Default
-e	--exit	<num>	Exit with this status code after printing.	0
-h	--help		Print help information and exit.
-i	--indent		Indent the line.
	--stderr		Print to STDERR instead of STDOUT.
-t	--timestamp		Include a timestamp.

Custom Prefix:

To use a custom prefix (or no prefix), run fyi print [flags] [options] <MSG>, using the following additional options:

Short	Long	Value	Description	Default
-p	--prefix	<txt>	Set a custom prefix.
-c	--prefix-color	<num>	Prefix color.	199

The color should be a u8 corresponding to a BASH color number. Note: to avoid the cost of re-alignment, only values in the range of 1..=255 are supported.

Confirmation Prompt:

To prompt a user for a Y/N (and exit with a corresponding status code), run fyi confirm [flags] [options] <MSG>. Confirmation supports the same flags as the other built-in prefixes.

Blank Lines:

And finally, there is a convenient blank subcommand that does nothing but print a certain number of blank lines for you. Run fyi blank [flags] [options], which supports the following:

Short	Long	Value	Description	Default
-h	--help		Print help information and exit.
	--stderr		Print to STDERR instead of STDOUT.
-c	--count	<num>	Number of empty lines to print.	1
