bhop (bunnyhop)

what even is this tho??

Tl;dr: a tool to quickly work with your filesystem via saved shortcuts and historical movements. Allows user to both jump to other locations or open files in other locations in an editor of your choice with a single command.

I have a bash/zsh/nushell function named short that lets users jump to predefined directories easily.

The basic zsh function that I originally used was defined as:

short() {
    if [[ "$1" == "add" ]]; then
        if [ ! -f  ~/.config/.shorts/${2} ]; then
            echo "[cmd] \`short ${2}\` -> ${PWD}"
            ln -sf ./ ~/.config/.shorts/${2}
        fi
    else
        cd ~/.config/.shorts/${1}
    fi
}

However, as this required maintaining separate scripts for the various shells I use (nushell for personal, bash and zsh for work), I've found it very annoying to have to update the same script multiple times every time I want to add a new feature.

bhop (short for bunnyhop) is supposed to replicate the behavior of short, but in a single language so it's easily updated between various shells.

This iteration also includes many improvements over the very simple shell function used before (and doesn't clutter you're system with unnecessary symlinks).

install

Install requires cargo (obvi, since it's a tool written in Rust).

If you currently don't have rust or cargo set up on your system, just run the following command before installing bunnyhop

curl https://sh.rustup.rs -sSf | sh

Once cargo is installed, simply run the following to install bunnyhop:

cargo install bhop

The default runner alias set is hp, use this to call bunnyhop from the command line (unless you set a custom alias).

If you'd like to use a different alias to call bunnyhop from your terminal, simple set the environment variable "BHOP_SHELL_ALIAS" prior to running the cargo install bhop command.

If you'd like to change to a different alias after installion, again you can just set the environment variable "BHOP_SHELL_ALIAS" and rerun the appropriate cargo install bhop command.

Once everything is installed and the shell hooks added, you can open the config file to set your editor and other preferences by simply typing:

foo@bar:~$ hp configure # full command

The current build supports four different shells: nushell, zsh, powershell, and bash/dash/anything else that use ~/.bashrc.

To see where all your configuration resources were provisioned, use:

foo@bar:~$ hp locate
/home/you/.config/bhop

use

foo@bar:~$ hp version # show version
bunnyhop 🐇 v.0.8.6
foo@bar:~$ hp v # alternate command
bunnyhop 🐇 v.0.8.6

To add a shortcut to your directory with the shortcut name example:

foo@bar:~$ hp add . example
foo@bar:~$ hp + . example # alternate command

To add a shortcut to the /home/you/.config directory with the shortcut name configs:

foo@bar:~$ hp add /home/you/.config configs
foo@bar:~$ hp + /home/you/.config configs # alternate command

Of course, if you want to move to your /home/you/.config director and rename it to configs at the same time:

foo@bar:~$ hp /home/you/.config configs

To add a shortcut to a file that can be opened up in the set editor, use:

# will create a shortcut to init.vim named `init.vim`
foo@bar:~$ hp add /home/you/.configs/nvim/init.vim

# will create a shortcut to init.vim named `nvim-confs`
foo@bar:~$ hp add /home/you/.configs/nvim/init.vim nvim-confs

If a shortcut maps to a file and not a directory, open that file in your editor by "jumping" to it:

foo@bar:~$ hp init.vim # full command consistent with opening a directory for editing

To delete a shortcut with name example:

foo@bar:~$ hp remove example
foo@bar:~$ hp rm example # alternate command
foo@bar:~$ hp - example # alternate command

To jump to the example named directory:

foo@bar:~$ hp example

To jump to the example named directory and open your default configuration for that directory:

foo@bar:~$ hp group example
foo@bar:~$ hp grp example # alternate command
foo@bar:~$ hp ! example # alternate command

To jump to the example named directory and open your configuration for that directory named tests:

foo@bar:~$ hp group example tests
foo@bar:~$ hp grp example tests # alternate command
foo@bar:~$ hp ! example tests # alternate command

To list available hops:

foo@bar:~$ hp list
Shortcuts:
configs  -> /home/you/.config
back     -> /home/you/Documents
hop-conf -> /home/you/.config/bhop/bhop.toml
example  -> /home/you/project/example_directory
History:
src -> /home/you/projects/hop/src
hop -> /home/you/projects/hop
foo@bar:~$ hp ls # alternate command
foo@bar:~$ hp .. # alternate command

To list available hops that have hop in them:

foo@bar:~$ hp list *hop*
Shortcuts:
hop-conf -> /home/you/.config/bhop/bhop.toml
History:
src -> /home/you/projects/hop/src
hop -> /home/you/projects/hop

To grab the output path of the hop with shortcut name example:

foo@bar:~$ hp find example
/home/you/project/example_directory
foo@bar:~$ hp f example # alternate command
foo@bar:~$ hp ? example # alternate command

You can use hp like cd to move into directories or edit files in your current directory. This will then add that directory to the stored history and allow you to jump to it in the future without adding a shortcut directly.

foo@bar:~$ echo $PWD
/home/you/projects/hop

foo@bar:~$ ls
.gitignore
Cargo.toml
README.md
src
target

foo@bar:~$ hp src

foo@bar:~$ echo $PWD
/home/you/projects/hop/src

If you place a file named .bhop in a directory with a shortcut, you can set different "windows" or "functions" for that shortcut directory. An example .bhop file would look like:

foo@bar:~$ cat .bhop
test = "cargo test -- --nocapture"

[default]
files = ["src/*.rs"]

[tests]
files = ["tests/*.rs"]

[runners]
files = ["runners/*.rs", "runners/scripts/*"]

[notebooks]
editor = "jupyter-notebook"
files = ["examples/*.ipynb"]

Given the above .bhop file in a directory with shortcut name example_shortcut, you can run unit tests with the following commands:

foo@bar:~$ hp group example_shortcut test
...
foo@bar:~$ hp ! example_shortcut test # alternate command

Given the same .bhop file and the same shortcut name example_shortcut, you can open all the files and scripts in the runners folder in your default editor with:

foo@bar:~$ hp group example_shortcut runners
...
foo@bar:~$ hp ! example_shortcut runners # alternate command

general flow for resolving HP commands

Calling a hp command with a shortcut name or path will attempt to do three things to resolve where it should jump you to:

  1. Check if it is a valid location within the file system.
  2. Check if it is within the saved list of shortcuts manually added by the user.
  3. Check if it is within the history list of previous hp commands used by the user.

The order between 1) and 2) can be switched in your bhop.toml configuration file.

custom configuration

By default, you can find the configuration file for bhop at ~/.config/bunnyhop/bunnyhop.toml.

Check out the config file to see the current options available and to set your personal editors (default is vi for Unix and notepad for Windows).

Additionally, if you'd to use a location other than the default for your system to store the configuration files and SQLite database, you can set the following environment variables before running bhop.

  1. BHOP_CONFIG_DIRECTORY - Sets the directory the configuration files will be provisioned in. Defaults to ~/.config/bhop.

If your shell configuration file is set to a non-default location, you can set the following environment variables manually before building bhop and it will configure the runners in the location you set:

  1. BHOP_ZSH_CONFIG_DIR - Directory your .zshrc file is located.
  2. BHOP_BASH_CONFIG_DIR - Directory your .bashrc file is located.
  3. BHOP_NUSHELL_CONFIG_DIR - Directory your nushell env.nu file is located.
  4. BHOP_POWERSHELL_CONFIG_DIR - Directory your powershell profile.ps1 or Microsoft.PowerShell_profile.ps1 files are located.

todo

  1. Write a more comprehensive suite of unit tests.
  2. Add customized editor launch commands (ie allow flags when calling an editor to open a file).
  3. Make a Neovim plugin so I can easily navigate without opening a new terminal panel or closing current terminal panel.
