README

# Z shell configuration

We use Z shell extensively, on many kinds of systems. We use Z shell configurations and conventions that can help us with compatibility, flexibility, and portability. This repo describes our configurations and conventions. This repo has our typical starter setup for Z shell aliases, functions, settings, etc. In practice this works well with other Z shell tools, such as oh-my-zsh.

## zsh startup files

There are five startup files that zsh will read commands from in order:

```zsh
zshenv
zprofile
zshrc
zlogin
zlogout
```

## zsh startup files: when they load and what they do

### zshenv

`zshenv` is sourced on all invocations of the shell, unless the -f option is set.

What goes in it:

* Set up the command search path

* Other important environment variables

* Commands to set up aliases and functions that are needed for other scripts

What does NOT go in it:

* Commands that produce output

* Anything that assumes the shell is attached to a tty

### zprofile

`zprofile` is sourced in login shells. It is meant as an alternative to `zlogin` for `ksh` fans; the two are not intended to be used together, although this could certainly be done if desired.

What goes in it:

* Commands that should be executed only in login shells.

* As a general rule, it should not change the shell environment at all.

* As a general rule, set the terminal type then run a series of external commands e.g. fortune, msgs, etc.

What does NOT go in it:

* Alias definitions

* Function definitions

* Options

* Environment variable settings

### zshrc

`zshrc` is sourced in interactive shells.

What goes in it:

* Commands to set up aliases, functions, options, key bindings, for interactive use etc.

### zlogin

`zlogin` is like `zprofile`, except sourced after zshrc.

### zlogout

`zlogout` is sourced when login shells exit.

### extras

Some zsh setups provide more files that are not read by zsh:

* `.zsh-update`: contains a timestamp of the most recent update

* `.zshrc-e`: an example file; the Z shell convention is example files end in `-e`.

## zsh file locations

The default location for zsh system files:

```zsh
/etc/zshenv
/etc/zprofile
/etc/zshrc
/etc/zlogin
/etc/zlogout
```

The default location for zsh user files:

```zsh
$HOME/.zshenv
$HOME/.zprofile
$HOME/.zshrc
$HOME/.zlogin
$HOME/.zlogout
```

The custom location for zsh user files uses the environment variable `ZDOTDIR`:

```zsh
${ZDOTDIR:-$HOME}/.zshenv
${ZDOTDIR:-$HOME}/.zprofile
${ZDOTDIR:-$HOME}/.zshrc
${ZDOTDIR:-$HOME}/.zlogin
${ZDOTDIR:-$HOME}/.zlogout
```

## zsh directory locations

Our location for zsh system directories:

```zsh
/etc/zshenv.d
/etc/zprofile.d
/etc/zshrc.d
/etc/zlogin.d
/etc/zlogout.d
```

Our default location for zsh user directories:

```zsh
$HOME/.config/zshenv.d
$HOME/.config/zprofile.d
$HOME/.config/zshrc.d
$HOME/.config/zlogin.d
$HOME/.config/zlogout.d
```

Our custom location for zsh user directories uses the environment variable `XDG_CONFIG_HOME`:

```zsh
${XDG_CONFIG_HOME:-$HOME/.config}/zshenv.d
${XDG_CONFIG_HOME:-$HOME/.config}/zprofile.d
${XDG_CONFIG_HOME:-$HOME/.config}/zshrc.d
${XDG_CONFIG_HOME:-$HOME/.config}/zlogin.d
${XDG_CONFIG_HOME:-$HOME/.config}/zlogout.d
```

## Repo files

This repo contains our Z shell conventions for subdirectories and also our files that we like to use with multiple teams.

Notable subdirectories:

* `zshenv.d/functions` is for functions.

* `zshenv.d/programs` is for configuring environment programs via environment variables, such as `$EDITOR`, `$PAGER`, etc.

* `zshenv.d/settings` is for Z shell settings, such as for completion, history, etc.

* `zshrc.d/aliases` is for aliases, such as `g` for `git`, `now` for printing the current time, etc.

### Conventions

Alias conventions:

* For an alias that is a one-letter shortcut, we use a naming convention for the file: the letter, an equal sign, and the result. For example, the file `g=git.zsh` is the alias that sets `g` to run `git`.

* For an alias that is intended to launch a program, we use a convention of trying probable locations for the tool. For example, for the alias `firefox`, we look in order in `/opt` (e.g. typical for our custom installs), then on the path, then in the typical macOS location.

Environment program conventions:

* `$EDITOR` for editing text files, such as `vi` or `emacs`.

* `$PAGER` for showing text files, such as `more` or `less`.

* `$FINDER` for searching text files, such as `grep` or `rg`.

* `$CLIPPER` for copying text to a clipboard, such as `xclip` or `pbcopy`.

* `$DATER` for showing dates and times, such as `date` or `gdate`.

* `$JUMPER` for moving among directories, such as `jump` or `jumpdir`.

Date/time format conventions:

* We default to nanoseconds precision (not seconds precision), because we use subsecond precision on some of our systems.

* We default to UTC timezone and the format "+00:00" (not "Z"), because this maximizes our compatibility with fintech systems and logs.

### Install

Clone:

```zsh
git clone https://github.com/sixarm/sixarm_zsh_config
```

Move the directories and files as you like, to wherever you want.

### Install for one user using the way we prefer

For one user, we prefer to put files in a user's configuration directory:

```zsh
config=${XDG_CONFIG_HOME:-$HOME/.config}
```

Make directories:

```zsh
mkdir -p $config/{zshenv.d,zprofile.d,zshrc.d,zlogin.d,zlogout.d}
```

Copy files:

```zsh
cp -R sixarm-zsh-config/zshenv.d/* $config/zshenv.d
cp -R sixarm-zsh-config/zprofile.d/* $config/zprofile.d
cp -R sixarm-zsh-config/zshrc.d/* $config/zshrc.d
cp -R sixarm-zsh-config/zlogin.d/* $config/zlogin.d
cp -R sixarm-zsh-config/zlogout.d/* $config/zlogout.d
```

Add this to the user file `.zshenv`:

```zsh
config=${XDG_CONFIG_HOME:-$HOME/.config}
for file in $config/zshenv.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```

Add this to the user file `.zprofile`:

```zsh
config=${XDG_CONFIG_HOME:-$HOME/.config}
for file in $config/zprofile.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```

Add this to the user file `.zshrc`:

```zsh
config=${XDG_CONFIG_HOME:-$HOME/.config}
for file in $config/zshrc.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```

Add this to the user file `.zlogin`:

```zsh
config=${XDG_CONFIG_HOME:-$HOME/.config}
for file in $config/zlogin.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```

Add this to the user file `.zlogout`:

```zsh
config=${XDG_CONFIG_HOME:-$HOME/.config}
for file in $config/zlogout.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```

### Install for the system using the way we prefer

For the system, we prefer to put files in the system's `/etc` directory:

```zsh
config=/etc
```

Make directories:

```zsh
mkdir -p $config/{zshenv.d,zprofile.d,zshrc.d,zlogin.d,zlogout.d}
```

Copy files:

Add this to the system file `zshenv`:

```zsh
config=/etc
for file in $config/zshenv.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```

Add this to the system file `/etc/zprofile`:

```zsh
config=/etc
for file in $config/zprofile.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```

Add this to the system file `zshrc`:

```zsh
config=/etc
for file in $config/zshrc.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```

Add this to the system file `zlogin`:

```zsh
config=/etc
for file in $config/zlogin.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```

Add this to the sytem file `zlogout`:

```zsh
config=/etc
for file in $config/zlogout.d/**/*(.N)
do
[ -x "$file" ] && . "$file"
done
```
