g.sh

## We keep the mappings of shortcuts to directories in this file.
## It has one mapping per line, and each line is in the format
## "<shortcut> <directory path>". Theres actually no need to keep
## this file in the same place as the dictionary if you want to put
## it somewhere else.
G_DICTIONARY_PATH="/home/$USER/Documents/code/g/dictionary.txt"

## This is implemented as a function rather than a script since
## running a script would fork a new process, so we couldn't change
## the original shell's environment. Since thats the whole point,
## we do it as a build in function in the original shell.
