PathPicker

Facebook PathPicker is a simple command line tool that solves the perpetual problem of selecting files out of bash output. PathPicker will:

• Parse all incoming lines for entries that look like files
• Present the piped input in a convenient selector UI
• Allow you to either:
  • Edit the selected files in your favorite $EDITOR
  • Execute an arbitrary command with them

It is easiest to understand by watching a simple demo:

Examples

After installing PathPicker, using it is as easy as piping into fpp. It takes a wide variety of input -- try it with all the options below:

• git status | fpp
• hg status | fpp
• git grep "FooBar" | fpp
• grep -r "FooBar" . | fpp
• git diff HEAD~1 --stat | fpp
• find . -iname "*.js" | fpp
• arc inlines | fpp

and anything else you can dream up!

Requirements

PathPicker should work with most Bash environments and requires Python >2.6 and <3.0.

ZSH is supported as well but won't have a few features like alias expansion in command line mode.

Installing PathPicker

Homebrew

Installing PathPicker is easiest with Homebrew for mac:

• brew update (to pull down the recipe since it is new)
• brew install fpp

Linux

On debian systems, installation can be done by installing the debian package from here

On Arch Linux, PathPicker can be installed from Arch User Repository (AUR). the AUR fpp-git package.

If you are on another system, or prefer manual installation, please follow the instructions given below.

Manual Installation

However if you're on a system without Homebrew, it's still quite easy to install PathPicker since it's essentially just a bash script that calls some Python. These steps more-or-less outline the process:

• cd /usr/local/ # or wherever you install apps
• git clone git@github.com:facebook/PathPicker.git
• cd PathPicker/

Here we make a symbolic link from the bash script in the repo to /usr/local/bin/ which is assumed to be in the current $PATH

• ln -s "$(pwd)/fpp" /usr/local/bin/fpp
• fpp --help # should work!

Add-ons

For tmux users, you can additionally install tmux-fpp which adds a key combination to run PathPicker on the last received stdout. It makes jumping into file selection mode even easier -- check it out here.

Advanced Functionality

As mentioned above, PathPicker allows you to also execute arbitrary commands with the specified files. Here is an example showing a git checkout command executed against the selected files:

The selected files are appended to the command prefix to form the final command. If you need the files in the middle of your command, you can use the $F token instead, like:

cat $F | wc -l

How PathPicker works

PathPicker is a combination of a bash script and some small Python modules. It essentially has three steps:

• First in the bash script, it redirects all standardout in to a python module that parses and extracts out the filenames. This data is saved in a temporary file and the python script exits.
• Next, the bash script switches to terminal input mode and another python module reads out the saved entries and presents them in a selector UI built with curses. The user either selects a few files to edit or inputs a command to execute.
• Lastly, the python script outputs a command to a bash file that is later executed by the original bash script.

It's not the most elegant architecture in the world but (in our opinion) provides a lot of utility.
