It is a shy shell prompt theme made in Rust. Shy means that it leaves nothing in you environment. No .config, no variables. Well, except polluting the env variables... Didn't think it through

Why

1. As a fun thing
2. I was bored
3. Eye candy
4. Make using the command line more comfortable
5. Main reason is, though, using Starship is for normies. Real nerds write their own shell prompts

And I called it Blazesh in reference to the meme, not like it was created to be brazingly fast

Installation

You can install it using:

cargo install --git https://github.com/rdsq/blazesh

And then add one of these to your shell config file (just don't forget to add ~/.cargo/bin to PATH):

Bash ~/.bashrc

eval "$(blazesh setup bash)"

Zsh ~/.zshrc

eval "$(blazesh setup zsh)"

Bash or Zsh autodetect

eval "$(blazesh setup detect)"

Fish ~/.config/fish/config.fish

source (blazesh setup fish | psub)

Features & Configuration

Here is how you can configure Blazesh with environment variables:

Git

It shows a git panel, yes it kind of takes time to load, but it is helpful

• + represents the uncommitted changes
• ↑ represents unpushed changes
• ↓ represents unpulled changes

You can configure how it handles git by changing the BLAZESH_GIT_MODE environment variable. Possible values:

• unoptimized - check git status every time, even if it is not a git repository
• optimized (default) - check git status only if the current directory or one of its parents is a git repository. Best for functionality
• optimized-cwd - like optimized, but checks only the current directory, doesn't check its parents
• static - just show [git] if the current directory or one of its parents is a git repository. Does not check any status or anything. Best for performance
• static-cwd - like static, but checks only the current directory
• disabled - completely disable git integration

And yes, you can use non 🦅🦅🦅🦅🦅🦅 spelling

Colors

(probably the main feature of this project)

You can set the color of the path in the prompt by editing BLAZESH_ACCENT_COLOR. You can set it to any number 0-7 and 9 representing the ANSI color codes, and also any RGB value. You can also set it to a sequence of colors, and it will show them as repeating colors. Examples:

• 5 - magenta
• 9 - default color (usually white or black)
• 4 3 - 🇺🇦
• 4 4 4 4 3 3 3 3 - same as the previous one, but more readable
• 0 1 2 3 4 5 6 7 - full ANSI rainbow
• FF0000 FF7F00 FFFF00 00FF00 00FFFF 0000FF 8B00FF - actual rainbow 🌈

RGB values can be written either as hexadecimal (e.g. FF9900) or as decimal (e.g. 255,153,0)

But it also has the second mode: gradient

You can set a gradient between any two or more RGB values by following the gradient [color1] [color2] ... [color_n] syntax

For example, set the BLAZESH_ACCENT_COLOR environment variable to gradient 0057B7 FFD700 to see the gradient between the official 🇺🇦 colors

You can even define gradient looping! This means that app the colors will repeat after certain number of characters

# For RGB
export BLAZESH_ACCENT_COLOR="gradient FF0000 00FF00 0000FF interval=10"

And the default color is a looping gradient too! It is gradient FF9900 FFFF00 interval=10

And you can define gradient offset. This one is not as visible, but it allows you to add a little dynamic time based glow to it for example

function _blazesh_time_offset {
    export BLAZESH_ACCENT_COLOR="gradient ff9900 ffff00 interval=10 offset=$(date +%s)"
}
precmd_functions+=(_blazesh_time_offset)

And you can also set the accent color to none to disable the colors in the path. Not sure why, but you can

Path

Use BLAZESH_PATH_DEPTH to edit how many directories to show before replacing them with …. Any number from 0 to 255. Default: 2

(It uses Unicode HORIZONTAL ELLIPSIS … instead of three dots ... to save some screen space. That's the point, after all)

Examples with values and how it displays the path:

• 0 - …
• 1 - …/src
• 2 (and higher) - ~/blazesh/src

Exit codes format

You can change how exit codes will be shown in the prompt by editing BLAZESH_EXIT_CODE_FORMAT. Possible values:

• code: just the code, no message, if you like it serious. Example: [130]
• message: just show the message if available, good for being compact. Example: [SIGINT]
• both (default): show both the code and the message. Example: [130/SIGINT]

(does not work in Bash for whatever reason)

Path shorthands

By default, it shortens $HOME as ~, but you can define your own custom shorthands with BLAZESH_PATH_SHORTHANDS in path:shorthand format. Just don't forget to add $HOME:~ first

For example, $HOME:~;/root:r~ would show paths as:

• $HOME/something: ~/something
• /root/something: r~/something

Non-default shell

This prompt can also show that you're using a shell that is different from the default one set with chsh

If you want to disable this, set BLAZESH_NON_DEFAULT_SHELL to disabled

ls

This one was made to feel more comfortable using the command line, it shows the contents of your current directory as (DIRS FILES DOTS) (disabled by default)

You can enable it by setting BLAZESH_LS=enabled. You can also configure the dots mode. (dots referring to all items starting with ., e.g. .git, .zshrc)

You can change your preferred dots mode with:

• dots=ignored: does not count any dots. You can think of it as default ls
• dots=separate (default): counts dots into a separate category (shown in the example), marked grey
• dots=counted: counts dots just like any other items. Think of it as ls --all

Example configurations

Insanity

You have the freedom to make your command prompt look insane if you are

export BLAZESH_ACCENT_COLOR='0 1 2 3 4 5 6 7'
export BLAZESH_PATH_DEPTH=255

Random color every session

You can put this to your .bashrc/.zshrc or wherever you store your configs and get a new accent color every time you open the shell

ansi_colors=(0 1 2 3 4 5 6 7)
export BLAZESH_ACCENT_COLOR=$(printf "%s\n" "${ansi_colors[@]}" | shuf -n 1)

Or random RGB color:

export BLAZESH_ACCENT_COLOR="$(printf '#%06X\n' $((RANDOM * RANDOM % 16777216)))"

Or random gradient:

# Generate 12 random hex cluster
random_hex=$(xxd -p -l 6 /dev/urandom)

# Split in two
color1="#${random_hex:0:6}"
color2="#${random_hex:6:6}"

export BLAZESH_ACCENT_COLOR="gradient $color1 $color2"

Color of your distro

This will make your prompt the color the developers of your operating system decided (does literally anything use this value?)

# I don't know how to use sed please don't get mad
distro_color="$(cat /etc/os-release | grep 'ANSI_COLOR=' \
    | sed 's/ANSI_COLOR="38;2;//' | sed 's/"//' | sed 's/;/,/g')"

if [[ -n "$distro_color" ]]; then
    export BLAZESH_ACCENT_COLOR="$distro_color"
fi

And you can do that with so much more, like days of the week, hours, whatever you wish!
