Improved shell ENVironment

This is a set of opinioned dotfiles used by me in daily work and in production. The goal is to have robust, customizable and portable set of defaults for linux bash shell for daily work.

Tested on macOS and linux hosts.

Features

• easy to customize / extend
• space aware smart/adaptive prompt
• highlighted error exit codes
• optimized for solarized colors
• handy aliases (system, git, etc)
• time of last activity
• fast git integration (current branch, branch state, defaults)
• root and remote host indicator
• sane vim defaults (pathogen, ctrlp, list-chars, solarized theme, ag-integration, tweaks, ...)
• readline tweaks
• tmux support
• respect non-interactive sessions

Installation

git clone https://github.com/denyskoch/ienv ~/.ienv && ~/.ienv/install.sh

You should also install Solarized color theme for your terminal. (ethanschoonover.com/solarized)

For faster and better fuzzy search results install ag the silver searcher:

brew install ag

Customizing / Extending

You can edit and customize your .baschrc, .vimrc, .tmux.conf as usual. IENV is integrated gracefully (no symlinks, no file copies), so things should not break. Take a look at your .bashrc for example:

...

### IENV ###
[ -r ~/.ienv/entrypoint ] && source ~/.ienv/entrypoint
### VNEI ###

Since its just an include, you can simple add or override settings you like.

Dark color theme

Simply switch terminal color theme e.g. solarized dark:

Shell

• automatically cd to directory:

  /work $ kitchen
  cd -- kitchen
  /work/kitchen $ 

• auto correct wrong spelled directories

  /work/demo $ ls
  abc bar foo          
                                                                                 
  /work/demo $ cd bra                                                                      
  /work/demo/bar $ 

• search in bash history with arrow keys e.g.:

  /work/demo/bar $ ssh<arrow up>

Known issues

Feel free to open a new issue on GitHub.

macOS bash

bash: shopt: autocd: invalid shell option name
bash: shopt: dirspell: invalid shell option name
bash: update_terminal_cwd: command not found

Since macOS is using a old version of bash, this errors will occur.

Bash v4+ is required, you can install it via brew brew install bash (brew.sh)

Vim issues in dark terminals

If you use dark terminal theme, you need to add set background=dark to your .vimrc
