run-dev-container.fish

#!/usr/bin/env fish
# Helper script to run Claude Code development container
#
# Usage:
#   ./run-dev-container.fish              Run the devcontainer image
#   ./run-dev-container.fish my-image:tag Run a custom container image
#
# The gcc/clang flavours this script used to accept are gone: they mapped to
# `make build-gcc` / `make build-clang`, which produced identical images
# because the SPACK_COMPILER build arg they passed was never declared by the
# Dockerfile. The dependency tree is built with GCC, fixed by the
# `packages: all: require:` line in .devcontainer/spack.yaml.

# Ensure we're in the project directory
cd (dirname (status --current-filename))

# Ensure ~/.claude-container exists
mkdir -p $HOME/.claude-container

# Default image (should match IMAGE_NAME in Makefile, tag built by `make build`)
set image_name shoccs-devcontainer

# Resolve the container image from the argument
set -q argv[1]; or set argv[1] $image_name:latest
set container $argv[1]
set name (string split -r -m1 : $container)[1]

# Colors for output
set GREEN '\033[0;32m'
set BLUE '\033[0;34m'
set NC '\033[0m' # No Color

# Find a free host port (starting at 8000) to forward to container port 8000.
# Avoids "Bind for 0.0.0.0:8000 failed: port is already allocated" when another
# process/container already holds the port. No manual editing required.
