modify lua bash script to work with cygwin and mingw on windows

[tapir]

Hi,

For people that want to use ulua from cygwin or mingw can you modify the bash script to work with it. With my limited bash-fu I rewrote the bash file. Everything seems to be OK yet somehow it can't find the __init module.

Here is the file if you want a headstart

#!/bin/bash
if [[ "$(arch)" == *"32"* ]]; then
  LJ_ARCH="x86"
elif [[ "$(arch)" == *"64"* ]]; then
  LJ_ARCH="x64"
else
  echo "ERROR - Unsupported system architecture: $(arch)" 1>&2 && exit 1
fi

if [[ "$(uname -s)" == *"MINGW"* ]] || [[ "$(uname -s)" == *"CYGWIN"* ]]; then
  LJ_SYS="Windows"
elif [[ "$(uname)" == "Darwin" ]]; then
  LJ_SYS="OSX"
elif [[ "$(uname -s)" == *"Linux"* ]]; then
  LJ_SYS="Linux"
else
  echo "ERROR - Unsupported system: $(uname -s)" 1>&2 && exit 1
fi

if [[ "$LJ_SYS" == "Windows" ]]; then
  SO_EXT="dll"
else
  SO_EXT="so"
fi

LJ_VER_EXT="luajit/2_1_head20151128"
LUA_ROOT="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
LJ_CORE="$LUA_ROOT/$LJ_VER_EXT/$LJ_SYS/$LJ_ARCH"
LUA_PATH="$LJ_CORE/?.lua;$LUA_ROOT/?/init.lua;$LUA_ROOT/?.lua;$LJ_CORE/?/init.lua;"
LUA_CPATH="$LUA_ROOT/?.$SO_EXT;$LUA_ROOT/loadall.$SO_EXT;"

export LUA_ROOT="$LUA_ROOT"
export LUA_PATH="$LUA_PATH"
export LUA_CPATH="$LUA_CPATH"

"$LJ_CORE/luajit" -l__init $@
