The installer for uv 0.4.22
This script detects what platform you're on and fetches an appropriate archive from
https://github.com/astral-sh/uv/releases/download/0.4.22
then unpacks the binaries and installs them to
\$CARGO_HOME/bin (or \$HOME/.cargo/bin)
It will then add that dir to PATH by adding the appropriate line to your shell profiles.
USAGE:
uv-installer.sh [OPTIONS]
OPTIONS:
-v, --verbose
Enable verbose output
-q, --quiet
Disable progress output
--no-modify-path
Don't configure the PATH environment variable
-h, --help
Print help information

# See discussion of late-bound vs early-bound for why we use single-quotes with env vars

install() {
# This code needs to both compute certain paths for itself to write to, and
# also write them to shell/rc files so that they can look them up to e.g.
# add them to PATH. This requires an active distinction between paths
# and expressions that can compute them.
#
# The distinction lies in when we want env-vars to be evaluated. For instance
# if we determine that we want to install to $HOME/.myapp, which do we add
# to e.g. $HOME/.profile:
#
# * early-bound: export PATH="/home/myuser/.myapp:$PATH"
# * late-bound: export PATH="$HOME/.myapp:$PATH"
#
# In this case most people would prefer the late-bound version, but in other
# cases the early-bound version might be a better idea. In particular when using
# other env-vars than $HOME, they are more likely to be only set temporarily
# for the duration of this install script, so it's more advisable to erase their
# existence with early-bounding.
#
# This distinction is handled by "double-quotes" (early) vs 'single-quotes' (late).
#
# However if we detect that "$SOME_VAR/..." is a subdir of $HOME, we try to rewrite
# it to be '$HOME/...' to get the best of both worlds.
#
# This script has a few different variants, the most complex one being the
# CARGO_HOME version which attempts to install things to Cargo's bin dir,
# potentially setting up a minimal version if the user hasn't ever installed Cargo.
#
# In this case we need to:
#
# * Install to $HOME/.cargo/bin/
# * Create a shell script at $HOME/.cargo/env that:
# * Checks if $HOME/.cargo/bin/ is on PATH
# * and if not prepends it to PATH
# * Edits $HOME/.profile to run $HOME/.cargo/env (if the line doesn't exist)
#
# To do this we need these 4 values:
# The actual path we're going to install to
local _install_dir
# The directory C dynamic/static libraries install to
local _lib_install_dir
# The install prefix we write to the receipt.
# For organized install methods like CargoHome, which have
# subdirectories, this is the root without `/bin`. For other
# methods, this is the same as `_install_dir`.
