Jump

Very lightweight tool to bookmark some directories and jump to them quickly

Requirements

• GHC
• Linux

Installation

Download this repository and run the command below. Install configuration options are available in config.mk

make install

Usage

Creating a bookmark

Cd to directory you want to bookmark and give it a little name

cd ~/I/love/this/directory/so/much
jump --bookmark favorite_dir_ever

If you don't give it a name, the bookmark's name will default to the directory's name:

cd ~/I/love/this/directory/so/much
jump --bookmark
# stdout: Added a bookmark with name "much"

Cd to bookmarked directory

Go to directory by name

jump favorite_dir_ever

Remove bookmarked directory

jump --clear name_of_the_bookmark_that_has_fallen_out_of_grace

Environments

If you want some commands to be executed after jump (e.g. rename the terminal, conda activate, etc.), write down the commands to ~/.config/jump/default_env.sh (a.k.a. default environment file) and execute:

jump favorite_dir_ever -e
# Alternatively
# jump favorite_dir_ever --env

You can create and use non-default environment files in ~/.config/jump/. If python_env.sh is the name of the file you created, call it using:

jump favorite_dir_ever -e python_env

(Note: The space between an option taking an optional argument like -e and its argument isn't kosher. Some (not me) would prefer to write -e=python_env. If you wish Jump to have this behavior, install it using the following command:)

make install ORIGINAL_GETOPTS=1

How it works

The difficulty is that a subprocess cannot modify characteristics of the parent process (in particular, its current working directory). To hack one's way around the problem, make install creates a bash function jump in your .bashrc. This function jump itself calls a Haskell program which gives bash instructions to be sourced by the jump function.
