Update sample and scaffold files (#14568)

# Description

Tidying up some of the wording of the sample and scaffold files to align
with our current recommendations:

* Continue to generate a commented-only `env.nu` and `config.nu` on
first launch.
* The generated `env.nu` mentions that most configuration can be done in
`config.nu`
* The `sample_env.nu` mentions the same. I might try getting rid of
`config env --sample` entirely (it's new since 0.100 anyway).
* All configuration is now documented "in-shell" in `sample_config.nu`,
which can be viewed using `config nu --sample` - This means that
environment variables that used to be in `sample_env.nu` have been moved
to `sample_config.new`.

# User-Facing Changes

Doc-only

# Tests + Formatting

Doc-only changes, but:

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# After Submitting

Need to work on updates to Config chapter

# ---------------------------------------------------------------------------------------
# Environment Variables
# ---------------------------------------------------------------------------------------
# In addition to the $env.config record, a number of other environment variables
# also affect Nushell's behavior:
# PROMPT_*
# --------
# Prompt configuration
# PROMPT_ variables accept either a string or a closure that returns a string
# PROMPT_COMMAND
# --------------
# Defines the primary prompt. Note that the PROMPT_INDICATOR (below) is appended to this value.
# Simple example - Static string:
$env.PROMPT_COMMAND = "Nushell"
# Simple example - Dynamic closure displaying the path:
$env.PROMPT_COMMAND = {|| pwd}
# PROMPT_COMMAND_RIGHT
# --------------------
# Defines a prompt which will appear right-aligned in the terminal
$env.PROMPT_COMMAND_RIGHT = {|| date now | format date "%d-%a %r" }
# PROMPT_INDICATOR*
# -----------------
# The prompt indicators are environmental variables that represent
# the state of the prompt. The specified character(s) will appear
# immediately following the PROMPT_COMMAND
# When in Emacs mode (default):
$env.PROMPT_INDICATOR = "> "
# When in normal vi mode:
$env.PROMPT_INDICATOR_VI_NORMAL = "> "
# When in vi insert-mode:
$env.PROMPT_INDICATOR_VI_INSERT = ": "
# When a commandline extends across multiple lines:
$env.PROMPT_MULTILINE_INDICATOR = "::: "
# TRANSIENT_PROMPT_*
# ------------------
# Allows a different prompt to be shown after a command has been executed. This
# can be useful if you have a 2-line prompt. Instead of each previously-entered
# command taking up at least 2 lines, the transient prompt can condense it to a
# shorter version. The following example shows a rocket emoji before each
# previously-entered command:
$env.TRANSIENT_PROMPT_COMMAND = "🚀 "
$env.TRANSIENT_PROMPT_INDICATOR = ""
$env.TRANSIENT_PROMPT_INDICATOR_VI_INSERT = ""
$env.TRANSIENT_PROMPT_INDICATOR_VI_NORMAL = ""
# Tip: Removing the transient multiline indicator and right-prompt can simplify
# copying from the terminal
$env.TRANSIENT_PROMPT_MULTILINE_INDICATOR = ""
$env.TRANSIENT_PROMPT_COMMAND_RIGHT = ""
# ENV_CONVERSIONS
# ---------------
# Certain variables, such as those containing multiple paths, are often stored as a
# colon-separated string in other shells. Nushell can convert these automatically to a
# more convenient Nushell list. The ENV_CONVERSIONS variable specifies how environment
# variables are:
# - converted from a string to a value on Nushell startup (from_string)
# - converted from a value back to a string when running external commands (to_string)
#
# Note: The OS Path variable is automatically converted before env.nu loads, so it can
# be treated a list in this file.
#
# Note: Environment variables are not case-sensitive, so the following will work
# for both Windows and Unix-like platforms.
#
# By default, the internal conversion looks something like the following, so there
# is no need to add this in your actual env.nu:
$env.ENV_CONVERSIONS = {
"Path": {
from_string: { |s| $s | split row (char esep) | path expand --no-symlink }
to_string: { |v| $v | path expand --no-symlink | str join (char esep) }
}
}
# Here's an example converts the XDG_DATA_DIRS variable to and from a list:
$env.ENV_CONVERSIONS = $env.ENV_CONVERSIONS | merge {
"XDG_DATA_DIRS": {
from_string: { |s| $s | split row (char esep) | path expand --no-symlink }
to_string: { |v| $v | path expand --no-symlink | str join (char esep) }
}
}
#
# Other common directory-lists for conversion: TERMINFO_DIRS.
# Note that other variable conversions take place after `config.nu` is loaded.
# NU_LIB_DIRS
# -----------
# Directories in this constant are searched by the
# `use` and `source` commands.
#
# By default, the `scripts` subdirectory of the default configuration
# directory is included:
const NU_LIB_DIRS = [
($nu.default-config-dir | path join 'scripts') # add <nushell-config-dir>/scripts
($nu.data-dir | path join 'completions') # default home for nushell completions
]
# You can replace (override) or append to this list by shadowing the constant
const NU_LIB_DIRS = $NU_LIB_DIRS ++ [($nu.default-config-dir | path join 'modules')]
# An environment variable version of this also exists. It is searched after the constant.
$env.NU_LIB_DIRS ++= [ ($nu.data-dir | path join "nu_scripts") ]
# NU_PLUGIN_DIRS
# --------------
# Directories to search for plugin binaries when calling add.
# By default, the `plugins` subdirectory of the default configuration
# directory is included:
const NU_PLUGIN_DIRS = [
($nu.default-config-dir | path join 'plugins') # add <nushell-config-dir>/plugins
]
# You can replace (override) or append to this list by shadowing the constant
const NU_PLUGIN_DIRS = $NU_PLUGIN_DIRS ++ [($nu.default-config-dir | path join 'plugins')]
# As with NU_LIB_DIRS, an $env.NU_PLUGIN_DIRS is searched after the constant version
# Appending to the OS path is a common configuration task.
# Because of the previous ENV_CONVERSIONS (performed internally
# before your config.nu loads), the path variable is a list that can
# be appended to using, for example:
$env.path ++= "~/.local/bin"
# Or prepend using
$env.path = "~/.local/bin" ++ $env.path
# The `path add` function from the Standard Library also provides
# a convenience method for prepending to the path:
use std/util "path add"
path add "~/.local/bin"
path add ($env.CARGO_HOME | path join "bin")
# You can remove duplicate directories from the path using:
$env.PATH = ($env.PATH | uniq)
