Lua Rocks 設定 |

假設 /usr/local/bin/luarocks 是 luarocks-2.0.12 或更新版本，而 /usr/local/opt/lua/bin/lua 是 Lua 5.1.x，請建立預設 /usr/local/share/luarocks/config-5.1.lua (這是 Mountain Lion 上 Homebrew 的預設套件目錄，不過我在 Ubuntu 持續整合伺服器上也有一個非常相似的運作方式 — 毫無疑問，在 Windows 上也能使用批次檔 (BAT) 檔案完成類似的事情)
rocks_trees = { "/usr/local/lib/luarocks/5.1" }
variables = {
LUA = "/usr/local/opt/lua/bin/lua5.1",
LUA_BINDIR = "/usr/local/opt/lua/bin",
LUA_INCDIR = "/usr/local/opt/lua/include",
LUA_LIBDIR = "/usr/local/opt/lua/lib",
}
接著在 /usr/local/bin/luarocks5.1 建立一個包裝腳本
#!/bin/sh
PATH=/usr/local/opt/lua/bin:/usr/local/opt/luarocks/bin:$PATH
LUAROCKS_CONFIG=/usr/local/share/luarocks/config-5.1.lua
export LUAROCKS_CONFIG
lua5.1 `which luarocks` ${1+"$@"}
exit $?
同樣地，你需要在 /usr/local/bin/lua5.1 加入另一個包裝程式，以便設定路徑來尋找正確的 rock
#!/bin/sh
: ${LUA_PATH=";"}
: ${LUA_CPATH=";"}
PATH=/usr/local/opt/lua/bin:/usr/local/opt/luarocks/bin:$PATH
LUAROCKS_CONFIG=/usr/local/share/luarocks/config-5.1.lua
export LUAROCKS_CONFIG
# Set search paths to user environment settings, followed by system path, and finally rocks_trees.
save_LUA_PATH=$LUA_PATH
save_LUA_CPATH=$LUA_PATH
eval `luarocks path`
LUA_PATH="$save_LUA_PATH;$LUA_PATH"
LUA_CPATH="$save_LUA_CPATH;$LUA_CPATH"
exec lua5.1 ${1+"$@"}
在 /usr/local/opt/lua52/ 安裝 Lua 5.2.x 之後 (同樣地，這是 Mountain Lion 上 homebrew 的預設值)，儘管 brew lua52 的某些路徑與 brew lua 衝突，但你必須手動執行連結，因此你將需要一個新的 /usr/local/share/luarocks/config-5.2.lua
rocks_trees = { "/usr/local/lib/luarocks/5.2" }
variables = {
LUA = "/usr/local/opt/lua52/bin/lua",
LUA_BINDIR = "/usr/local/opt/lua52/bin",
LUA_INCDIR = "/usr/local/opt/lua52/include",
LUA_LIBDIR = "/usr/local/opt/lua52/lib",
}
並在 /usr/local/bin/luarocks5.2 建立一個包裝腳本
#!/bin/sh
PATH=/usr/local/opt/lua52/bin:/usr/local/opt/luarocks/bin:$PATH
LUAROCKS_CONFIG=/usr/local/share/luarocks/config-5.2.lua
export LUAROCKS_CONFIG
exec lua5.2 `which luarocks` ${1+"$@"}
以及 /usr/local/bin/lua5.2 的另一個包裝腳本
#!/bin/sh
: ${LUA_PATH=";"}
: ${LUA_CPATH=";"}
PATH=/usr/local/opt/lua52/bin:/usr/local/opt/luarocks/bin:$PATH
LUAROCKS_CONFIG=/usr/local/share/luarocks/config-5.2.lua
export LUAROCKS_CONFIG
# Set search paths to user environment settings, followed by system path, and finally rocks_trees.
save_LUA_PATH=$LUA_PATH
save_LUA_CPATH=$LUA_PATH
eval `luarocks path`
LUA_PATH="$save_LUA_PATH;$LUA_PATH"
LUA_CPATH="$save_LUA_CPATH;$LUA_CPATH"
exec lua5.2 ${1+"$@"}
LuaRocks 2.0.12 也適用於 luajit-2.0，因此我使用 /usr/local/share/luarocks/config-luajit.lua 建立第三組設定，並且在 /usr/local/bin/luarocks-luajit 和 /usr/local/bin/luajit 建立一對包裝程式。針對不同的作業系統進行調整 (例如 Ubuntu，它將套件安裝在 /usr/ 樹狀結構中) 只需要調整腳本和腳本中路徑的簡單動作即可。為了保險起見，我也建立了一個指向我偏好的預設解譯器的符號連結
$ ln -s lua5.2 /usr/local/bin/lua $ ln -s luarocks5.2 /usr/local/bin/luarocks
現在，你可以透過選擇使用 luarocks5.1 或 luarocks-luajit 等方式，安裝並對應的 LuaRocks 查詢樹狀結構，讓相關聯的 Lua 解譯器自動偵測。
