I maintain this separately from my other dotfiles. For the most part, these should be installed by by cloning this repo and following the "Installation" section below. A few things to note, however, that I always mess up:

• Follow the instructions exactly. All of them, including launching zsh to begin.
  • For real. They are specific, and invariably I try to copy them and get a stupid naming convention wrong, like the annoying prezto to .zprezto directory name, and mess something up. Just copy them, with the exception pointed out below.
  • Except: clone my own repo, not sorin-ionescu's as shown in the clone URL. Depending on my terminal (iTerm2, Ubuntu's), chsh might not be enough, so you might also have to do whatever the terminal of choice requires.
• See the next section on machine-specific configuration.

I have added a convention for machine-specific configuration that doesn't exist, so far as I know, in the original Prezto project. Alongside the runcoms/ directory, I've added a machine-specific/ directory. Config specific to certain machines (e.g. /usr/local/Cellar/ on a Mac) belongs in files in that directory.

In order to source those files appropriately, I've also taken to assigning each machine a name. E.g. my Macbook Air is mbair. The existence of a file ~/.zshMachineFlag_machineName indicates the current machine. Adding a line like this to runcoms/zshrc ensures that we source the file appropriately:

if [[ -a ~/.zshMachineFlag_mbair ]]; then
  source "${ZDOTDIR:-$HOME}"/.zprezto/machine-specific/mbair_zshrc
fi

Configuration that varies across platform (e.g. standard ls versions), is configured in .zprezto/machine-specific/<platform>_zshrc, with platform named according to the output of uname -s and converted to lower case. These files are sourced before machine-specific files to try allow more specific overrides.

Here are the steps to set this up for the first time:

• Determine a machine name. For this example we'll say it's foo.
• If custom configuration is required, add it to machine-specific/foo_zshrc.
• Execute touch ~/.zshMachineFlag_foo.
• Add these lines to runcoms/zshrc:

if [[ -a ~/.zshMachineFlag_foo ]]; then
  source "${ZDOTDIR:-$HOME}"/.zprezto/machine-specific/mbair_foo
fi

In this case we don't need to worry about editing the files. Just:

• touch ~/.zshMachineFlag_foo

vcs_info allows for integration of version control systems with your prompt. This can be slow, however, depending on the options you're supporting. check-for-changes in particular can be slow on big git repos like Chromium, e.g. To get around this, I've added a function based on this method that allows selective disabling of check-for-changes on a machine-specific basis.

In order to indicate that you do not want check-for-changes to be true, add an element to the ZSHMS_VCSINFO_NO_CHECK_CHANGES array with the absolute path to the directory you want ignored. See machine-specific/mbair_zshrc for an example. This variable is then looked for in the prompt command to selectively enable or disable check-for-changes.

Old README below.

Prezto is the configuration framework for Zsh; it enriches the command line interface environment with sane defaults, aliases, functions, auto completion, and prompt themes.

Prezto will work with any recent release of Zsh, but the minimum required version is 4.3.11.

1. Launch Zsh:

   zsh

2. Clone the repository:

   git clone --recursive https://github.com/sorin-ionescu/prezto.git "${ZDOTDIR:-$HOME}/.zprezto"

3. Create a new Zsh configuration by copying the Zsh configuration files provided:

   setopt EXTENDED_GLOB
   for rcfile in "${ZDOTDIR:-$HOME}"/.zprezto/runcoms/^README.md(.N); do
     ln -s "$rcfile" "${ZDOTDIR:-$HOME}/.${rcfile:t}"
   done

   Note: If you already have any of the given configuration files, ln will cause error. In simple cases you can load prezto by adding the line source "${ZDOTDIR:-$HOME}/.zprezto/init.zsh" to the bottom of your .zshrc and keep the rest of your Zsh configuration intact. For more complicated setups, it is recommended that you back up your original configs and replace them with the provided prezto runcoms.

4. Set Zsh as your default shell:

   chsh -s /bin/zsh

5. Open a new Zsh terminal window or tab.

If you are not able to find certain commands after switching to Prezto, modify the PATH variable in ~/.zprofile then open a new Zsh terminal window or tab.

Run zprezto-update to automatically check if there is an update to zprezto. If there are no file conflicts, zprezto and its submodules will be automatically updated. If there are conflicts you will instructed to go into the $ZPREZTODIR directory and resolve them yourself.

To pull the latest changes and update submodules manually:

cd $ZPREZTODIR
git pull
git submodule update --init --recursive

Prezto has many features disabled by default. Read the source code and accompanying README files to learn of what is available.

1. Browse /modules to see what is available.
2. Load the modules you need in ~/.zpreztorc then open a new Zsh terminal window or tab.

1. For a list of themes, type prompt -l.

2. To preview a theme, type prompt -p name.

3. Load the theme you like in ~/.zpreztorc then open a new Zsh terminal window or tab.

   Note that the 'git' module may be required for special symbols to appear, such as those on the right of the above image. Add 'git' to the pmodule list (under zstyle ':prezto:load' pmodule \ in your ~/.zpreztorc) to enable this module.

1. By default modules will be loaded from /modules and /contrib.

2. Additional module directories can be added to the :prezto:load:pmodule-dirs setting in ~/.zpreztorc.

   Note that module names need to be unique or they will cause an error when loading.

   zstyle ':prezto:load' pmodule-dirs $HOME/.zprezto-contrib

The project is managed via Git. It is highly recommended that you fork this project; so, that you can commit your changes and push them to GitHub to not lose them. If you do not know how to use Git, follow this tutorial and bookmark this reference.

The Zsh Reference Card and the zsh-lovers man page are indispensable.
