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.
