GCD - A different cd

Primary used for quickly navigating between git projects.

Supports

• git projects, the GCD database is populated using the gcd-init/gcd-update commands.
• non project folders, these can be added to the GCD database with gcd-add command.
• aliases for git project and non git project folders can be set using the gcd-alias command.

Note: A git project folders is a folder that has a '.git' sub folder, no other checks are done.

Installation

Currently you need to build the binaries your self.

prerequisites

A working Rust build system https://www.rust-lang.org/tools/install.

the code

Get the code from.

git clone https://gitlab.com/pnmtjonahen/pepercoin.git

Build and install it.

cargo install --path .

Once the console dependency is updated this will change in a normal cargo install

Installation

binaries

Install the binaries as described above.

script (unix)

Either copy the gcd script from the scripts folder into your ${HOME}/bin folder. (or equivalent, like ${HOME}/.cargo/bin)

Or create a gcd.sh script as follows

#!/bin/bash

SCRIPT_FILE="${HOME}/.gcd/gcd-cd.sh"

gcd-select $@

if [[ -f "${SCRIPT_FILE}" ]]; then
  source ${SCRIPT_FILE}
  rm ${SCRIPT_FILE}
fi

bash alias

And lastly, make an entry into your .bash_aliases file like:

alias gcd='source /home/user/.cargo/bin/gcd.sh'

Note: sourcing the shell script is needed else the internal 'cd' command will not work as expected.

script (windows)

Either copy the gcd.bat script from the scripts folder into your path folder. like ${APPDATA}/.cargo/bin

Or create a gcd script as follows

@echo off
call gcd-select
if exist %APPDATA%\.gcd\gcd-cd.bat (
    %APPDATA%\.gcd\gcd-cd.bat
    del /s %APPDATA%\.gcd\gcd-cd.bat
)

first time use

after installation call the gcd init to initialize the database and perform the initial search for projects_dir

gcd-init

Basic use

gcd is made up out of a number of different applications. Gcd-select is the main one, it is however not called directly but via a shell script.

• gcd-select, called from the gcd script and is used to select a project.
• gcd-init, initializes the database. it will overwrite the complete database. loosing all usage data, and aliases.
• gcd-alias, set an alias for the current folder, if the current folder is not a known project. nothing will happen.
• gcd-add, adds the current folder to the database.
• gcd-purge, purges aka removes all project from the database that are no longer available.
• gcd-delete, removes the current folder from the database.
• gcd-update, updates the database, as opposed to the gcd-init, this will only add projects that are not yet in the database
• gcd-mv, move a project onto a new folder. When moving git projects on disc use this to update the gcd database with the new location.
