用 Lua 来代替 Bash.md

lua_as_bash.md

• environment setup

amalg - merge several lua scripts into standalone one net-url - url parser luash - invoke sh commands from lua

brew install --use-clang luarocks
luarocks install --server=http://luarocks.org/dev amalg net-url luash

• write your main lua script

require('sh')

local wd = tostring(pwd()) -- calls `pwd` and returns its output as a string

local files = tostring(ls('/tmp')) -- calls `ls /tmp`
for f in string.gmatch(files, "[^\n]+") do
        print(f)
end

url = require "net.url"
query = url.parseQuery("first=abc&a[]=123&a[]=false&b[]=str&c[]=3.5&a[]=last")

print(query.a[2])

• generate dependency cache

lua -lamalg main.lua

• generate merged standalone lua script

amalg.lua -o out.lua -a -s main.lua -c
