#!/bin/bash
# Build tmuxrdr from this checkout and install it as ~/.local/bin/tmuxrdr
# (or $TMUXRDR_BIN). cargo's output is herdr's binary, target/release/herdr;
# the name it is installed under is all the renaming there is -- it starts its
# server from its own path, and src/config/io.rs gives it its own directories.
#
# Toolchains, found without PATH or shell-profile changes:
# Rust the version rust-toolchain.toml pins, through rustup; Homebrew's
# keg-only rustup (/opt/homebrew/opt/rustup/bin) is used when no
# cargo is on PATH
# Zig exactly 0.16.0, which herdr's vendored libghostty-vt requires:
# $ZIG, else ~/.local/opt/zig-0.16.0/zig
# sfw Socket Firewall, which every crate fetch goes through (Zig's
# packages are fetched first, by Zig, hash-checked)
#
# The binary is replaced by a rename, so a running tmuxrdr server keeps the
# old one until it is restarted.
