Installation

Using pipx to Install (preferred)

This package could be installed using pip like any other Python package (in fact, see the section below this one for instructions). Given that we only need this package's entry points (e.g. the funky command), however, we recommend that pipx be used instead (replace SHELL with either bash or zsh):

# install and setup pipx
python3 -m pip install --user pipx
python3 -m pipx ensurepath

# install and setup funky
pipx install pyfunky
funky --setup-shell SHELL

Using pip to Install

To install funky using pip, run the following commands in your terminal (replace SHELL with either bash or zsh):

python3 -m pip install --user pyfunky  # install funky
funky --setup-shell SHELL  # hook funky into your shell

If you don't have pip installed, this Python installation guide can guide you through the process.

Building from Source

You can either clone the public repository:

git clone git://github.com/bbugyi200/funky

Or download the tarball:

curl  -OL https://github.com/bbugyi200/funky/tarball/master

Once you have a copy of the source, you can install funky by running:

make install

The last thing you need to do is hook funky into your preferred shell, which can be accomplished with the following command (replace SHELL with either bash or zsh):

funky --setup-shell SHELL

Usage

Funks are manipulated using the funky and gfunky commands. These commands have the same user interface. The difference between the two commands is treated in the Local vs Global section.

Local vs Global

Local funks are stored using a hidden database file that is located in the same directory where the funk was created. These can be manipulated using the options described in the demo above (run funky -h to see descriptions of these options). Once created, a local funk can be used just like any other command or normal funk as long as you are inside of the directory where the local funk was originally defined.

Global funks, on the other hand, are stored in your home directory (/home/<user>) and can be used from any directory. Local funks can be used to override global funk definitions.

Local and global funks can be manipulated (created, removed, edited, renamed, etc.) by using the funky and gfunky commands, respectively.

Funk Definition Shortcuts

Normally when defining a funk, the provided raw definition (the final contents of the temp file) is inserted directly into the generated function definition. However, funky does try to make some alterations to the original funk definition when doing so is convenient. These funky definition shortcuts can make defining funks faster:

Special cd Funks

A funk definition of the form @./relative/path/to/directory will be automatically changed to

cd /absolute/path/to/directory/"$@" || return 1

Simulate Shell Variables

A funk definition of the form "Some string here..." will be automatically changed to

echo "Some string here..." "$@"

This allows you to use funks to simulate shell variables via command substitution.

The "$@" Special Parameter

This project originally used aliases. The decision to migrate to shell functions was made based on the fact that shell functions are far more capable than aliases. Moreover, there is very little benefit to using aliases over shell functions.

With that said, actual aliases do have one appeal over shell functions. When you use an alias, any arguments that you pass to it are automatically passed to the command definition (at runtime, aliases are just substituted with their definitions). For the purpose of emulating this behavior when it would typically be desired, a funk defined using a single-line command definition that does NOT already contain argument variables (e.g. does not contain $0, $1, ..., $9, $*, or $@) will automatically have the "$@" special parameter appended to its definition. This allows for the same automatic argument handling that you would expect from an alias.

See the official Bash docs for more information on Bash's special parameters.
