-AX-ZSH: Alex' Modular ZSH Configuration
-=======================================
+# AX-ZSH: Alex' Modular ZSH Configuration
-AX-ZSH is a modular configuration system for the Z shell. If provides sane
-defaults and is extendable by plugins.
+[AX-ZSH] is a modular configuration system for the Z shell ([ZSH]).
+It provides sane defaults and is extendable by plugins.
+AX-ZSH integrates well with [Powerlevel10k] and other extensions, even plugins
+of [OhMyZsh], see [below](#integration-with-other-projects).
-Configuration
--------------
+The homepage of [AX-ZSH] can be found at [GitHub]:
+<https://github.com/alexbarton/ax-zsh>.
-AX-ZSH can be configured using settings in a `$HOME/.zshenv` file.
+## Installation
-The following configuration variables are supported:
+Prerequisites:
-* `AXZSH_PLUGIN_D`: Optional directory for additional plugins.
-* `axzsh_default_plugins`: Array of default plugins, that will be loaded in
- addition to the core plugins. You can reset this array to disable(!) loading
- of these default plugins. Currently these plugins are loaded by default:
- * byebye
- * correction
- * history
- * ls
- * prompt
- * ssh
- * std_aliases
- * std_env
-* `axzsh_plugins`: Optional array of addiutional (non-core and non-default)
- plugins to load.
+* [ZSH] – obviously ;-)
+* [Git] (optional but recommended!)
-Example for a `$HOME/.zshenv` file:
+Installing AX-ZSH is a two-step process:
+1. Clone or copy the source files into the `~/.axzsh` directory,
+2. Run the `~/.axzsh/install.sh` script.
+
+The `install.sh` script creates symbolic links for `~/.zprofile`, `~/.zshrc`,
+`~/.zlogin`, and `~/.zlogout` (don't worry, already existing files are backed
+up).
+
+*Note:* The installation is per-user and only changes/installs files into the
+home directory of the current user (`~`). AX-ZSH is not meant to be installed
+globally for all users on a system at once, and you don't need to become "root"
+or any other user with elevated privileges!
+
+### Installation using Git
+
+When using [Git], the preferred method, it is best to directly clone the AX-ZSH
+repository into the `~/.axzsh` directory and call `install.sh` from this
+location:
+
+```sh
+git clone https://github.com/alexbarton/ax-zsh.git ~/.axzsh
+~/.axzsh/install.sh
+```
+
+### Installation without Git
+
+*Note:* If you do not install AX-ZSH with [Git], you will not be able to upgrade
+itself afterwards with the integrated `axzsh upgrade` command! Therefore this
+method is *not recommended* for normal use!
+
+```sh
+curl -Lo ax-zsh-master.zip https://github.com/alexbarton/ax-zsh/archive/refs/heads/master.zip
+unzip ax-zsh-master.zip
+mv ax-zsh-master ~/.axzsh
+~/.axzsh/install.sh
+```
+
+### Post-Installation Tasks
+
+After installing AX-ZSH, using Git or via an archive file, you should close all
+running ZSH sessions and restart them to activate AX-ZSH. And maybe you want to
+change your default shell to ZSH if you haven't already?
+
+For example like this:
+
+```sh
+# Set new default shell
+chsh -s $(command -v zsh)
+
+# Replace running shell with a ZSH login shell
+exec $(command -v zsh) -l
+```
+
+## Upgrade
+
+When you used Git to install AX-ZSH (and/or plugins), you can use the `axzshctl`
+command to upgrade AX-ZSH itself and external plugins like this:
+
+```sh
+axzshctl upgrade
+```
+
+## Usage
+
+AX-ZSH comes with a hopefully sane default configuration and can be extended
+using plugins. Different types of plugins are supported:
+
+* Plugins shipped with AX-ZSH.
+* Themes shipped with AX-ZSH.
+* 3rd-party plugins:
+ * installed manually into `$AXZSH/custom_plugins`
+ * stand-alone plugins stored on GitHub
+ * plugins of OhMyZsh from its GitHub repository
+* 3rd-party themes:
+ * installed manually into `$AXZSH/custom_themes`
+ * some stand-alone themes stored on GitHub
+
+### Check whether all locally available "useful" plug-ins are activated
+
+Most plugins can be enabled even when the commands they work with aren't
+available and won't do any harm. But to keep ZSH startup times low, you should
+only enable plugins that are useable on your local system and which you actually
+plan to use.
+
+You can use the following command to let AX-ZSH scan the status of all locally
+available plugins:
+
+```sh
+axzshctl check-plugins
+```
+
+It will summarize the status of all enabled plugins, and suggest to enable
+plugins which seem to make sense on the system and to disable enabled plugins
+that seem not to be supported (for example because of missing dependencies).
+
+### List enabled plugins
+
+Run the following command to list all currently enabled plugins:
+
+```sh
+axzshctl list-enabled
+```
+
+### Enable plugins
+
+AX-ZSH comes with a sane "core ZSH configuration", but it can show its true
+strengths when enabling additional plugins for additional tools and commands
+that are available on your system and you want to use.
+
+Different types of plugins are supported (see the introduction to the section
+"*usage*" above) which are differentiated by their identifier:
+
+* `<name>`: locally available plugin, either bundled with AX-ZSH itself, or
+ installed manually (see below).
+* `<repository>/<name>`: stand-alone [GitHub] repository.
+* `@ohmyzsh/<name>`: [OhMyZsh] plugin from the OhMyZsh GitHub
+ repository (see <https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins>).
+
+You can enable one or more plugins like this:
+
+```sh
+axzshctl enable-plugin <identifier> [<identifier> […]]
+```
+
+*Hint:* *Tab-completion* works for sub-commands and already locally available
+plugin names!
+
+Some examples:
+
+```sh
+# Enable some plugins bundled with AX-ZSH:
+axzshctl enable-plugin editor_select git ssh_autoadd
+
+# Enable the Powerlevel10k "theme plugin" from GitHub, see
+# <https://github.com/romkatv/powerlevel10k>:
+axzshctl enable-plugin romkatv/powerlevel10k
+
+# Enable the "fast-syntax-highlighting" plugin from GitHub, see
+# <https://github.com/zdharma-continuum/fast-syntax-highlighting>:
+axzshctl enable-plugin zdharma-continuum/fast-syntax-highlighting
+
+# Enable the Git and tmux plugins of OhMyZsh:
+axzshctl enable-plugin @ohmyzsh/git @ohmyzsh/tmux
+```
+
+#### Custom local plugins
+
+You can link custom plugins stored in arbitrary directories using `axzshctl`
+by specifying the complete path name. Or you can place additional plugins into
+the `$AXZSH/custom_plugins` folder which is searched by the `axzshctl` tool
+by default.
+
+In addition you can set the `AXZSH_PLUGIN_D` variable (and `ZSH_CUSTOM` like
+[OhMyZsh]) to specify additional plugin search directories.
+
+### Disable plugins
+
+Run the following command to disable a currently enabled plugin:
+
+```sh
+axzshctl disable-plugin <identifier> [<identifier> […]]
+```
+
+*Hint:* *Tab-completion* works for sub-commands and plugin names!
+
+### Update plugin cache
+
+AX-ZSH uses a "plugin cache" to speedup ZSH start times. This cache is
+automatically updated when using the `axzshctl` sub-commands, for example when
+enabling or disabling plugins, or when upgrading the AX-ZSH installation and
+all plugins.
+
+But you *have to* update the cache when manually installing plugins or during
+development of a own local plugin after updating its code!
+
+Run the following command to update the AX-ZSH cache:
+
+```sh
+axzshctl update-caches
+```
+
+### Other `axzshctl` sub-commands
+
+Please run `axzshctl --help` to get a full list of a available sub-commands:
+
+```sh
+axzshctl --help
```
-# Add additinal custom plugin search path
-export AXZSH_PLUGIN_D="/opt/ax-zsh-plugins"
-# Disable all default plugins
-axzsh_default_plugins=()
+## Integration with other projects
+
+### Powerlevel10k
+
+AX-ZSH supports [Powerlevel10k] out of the box, you just have to install it as a
+plugin:
-# Add additional plugins
-axzsh_plugins=(
- editor_select
- homebrew
-)
+```sh
+axzshctl enable-plugin romkatv/powerlevel10k
```
-Note: it should *not* be necessary to disable the default plugins! The above
-is an example only!
+*Hint:* Once the Powerlevel10k plugin theme is installed, you can use the
+regular `axzshctl set-theme` command to enable it, like for any other installed
+theme: `axzshctl set-theme powerlevel10k`.
+
+## AX-ZSH & local ZSH configuration
+
+Don't modify `~/.zprofile`, `~/.zshrc`, `~/.zlogin`, or `~/.zlogout`! These
+are links to "AX-ZSH"-private files that can become overwritten when updating.
+You can use the following files for local ZSH configuration:
-Environment Variables
----------------------
+1. AX-ZSH doesn't use `~/.zshenv` in any way. So you can use this file for your
+ own purposes (for example, to set up some environment variables that AX-ZSH
+ relies on).
+
+2. AX-ZSH reads the optional files `~/.zprofile.local`, `~/.zshrc.local`,
+ `~/.zlogin.local`, and `~/.zlogout.local` after its own core initialization
+ files when present.
+
+## Environment variables
Expected to be already set:
Validated and/or set up by core plugins:
-* `AXZSH`
+* `AXZSH` – AX-ZSH installation directory
* `HOST`
* `HOSTNAME` (same as HOST, deprecated)
* `LOCAL_HOME`
* `PS1`
* `SHORT_HOST`
* `TERM`
+* `TMPDIR` (set and always ends with a "/")
* `XDG_CACHE_HOME`
+* `XDG_RUNTIME_DIR`
* `ZSH_CACHE_DIR`
