BashJect

DISCLAIMER: This has only been tested on my machine! Please report bugs and comments

BashJect is a minimalist bash project manager. It allows you to switch your shell between different environnements. This is particularly useful for not polluting your main bashrc with environnement variables, aliases and functions specific to one project.

It works in a very simple yet configurable way:

• a centralized file keeps a list of project identifiers and root paths (var: {BASHJECT_PRJ_STORE})
• in each project root folder, a file is created (var: {BASHJECT_PRJ_FILE})
• When switching to a project, this file is sourced

Random features:

• Allow a simple dependency system: just use a "virtual" project to gather all common stuff and use the source command to make it available in other projects
• Renaming / removing projects
• list commands outputs project names separated by newlines (combine with dmenu to launch your favorite editor in the correct environment)
• Autocomplete included (for commands and args!)

Here's the help message:

Usage:
        - Add a project with 'bashject add name path'
        - Enter a project with 'bashject set name'
        - Customize his environment with 'bashject edit name' (or editing his {BASHJECT_PRJ_DIR}/{BASHJECT_PRJ_FILE})

    Exported vars:
        - BASHJECT_PRJ_NAME: name of the project
        - BASHJECT_PRJ_PATH: path to the root of the project

    Commands:
        - bashject a|add      name path     # Adds a project
        - bashject s|set      name          # Enter a project
        - bashject source     name          # Source the project file of the specified project (useful to handle common envs)
        - bashject edit       name          # Edit the project file of the specified project with {EDITOR}
        - bashject rm|remove  name          # Remove the project (no filesystem modifications)
        - bashject rename     old    new    # Rename the project (no filesystem modifications)
        - bashject path       name          # Echoes a project's path
        - bashject names                    # Echoes all projects, separated by whitespaces
        - bashject list                     # Echoes all projects, separated by newlines (useful with dmenu, for example)
        - bashject cd                       # cd to the current project root path
        - bashject help       [cmd]         # Display global or specific command help

    Configuration (to override values, define them before sourcing this file)
        - BASHJECT_PRJ_STORE                # File in which we store all projects configuration  (default: '', current: '/home/ben/work/.projects')
        - BASHJECT_PRJ_FILE                 # Name of the project file, created at his root and sourced on 'bashject set'  (default: '', current: '.prj_env')
        - BASHJECT_CHANGE_PROMPT            # 1 to change the prompt to '[ BASHJECT_PRJ_NAME ] PS1' > on 'bashject set'  (default: '', current: '1')
        - BASHJECT_ALIAS                    # Name of an alias for bashject to define (i.e: 'bj'), autocompletion will be handled (default: '', current: 'bj')
        - BASHJECT_TMP                      # Temp file used for rename and remove operations (default: '', current: '/tmp/bashject.tmp')
        - BASHJECT_CD_WHEN_SET              # Change for project directory when set command is called (default: '1', current: '1')

To use it, just source it from your main bashrc:

BASHJECT="$HOME/.bashject"
[ -f "$BASHJECT" ] && source $BASHJECT

Example of a dmenu integration, to launch gvim in an enhanced environment:

#!/bin/bash

source "$HOME/.bashject"
cmd=`bashject list | dmenu -i -p "Select Project " -nf '#888888' -nb '#222222' -sf '#ffffff' -sb '#285577'`
if [ ! -z $cmd ]; then
    bashject set $cmd
    exec gvim .
