One-liner to compile Lua templates
Lua syntax allows you to implement php-style patterns with just a few regular expressions.
First, let's see what happens.
<? require 'tracking'?>
And this is all going to one team in a regular module Lua:
In fact, to run, you need to write another short function:
A small library of three functions is available at Moon Rocks :
luarocks , in turn, is available in the Ubuntu repositories:
Project on github .
First, let's see what happens.
Variable substitution
<a href="<%url%>"><%label%></a> Logical constructions
<? if 1 > 2 then ?> <? else ?> <? end ?>
Cycles
<ul> <? for i = 1, 9999 do ?> <li> №<%i%></li> <? end ?> </ul>
Connecting other templates
<html> <script><? require "scripts" ?></script> <style><? require "styles" ?></style> ...
<? require 'tracking'?>
And any other designs on Lua
<? function warn() ?> <b> !</b> <? end ?> ... <? warn() ?> ... <? --[[ ?> <? --]] ?>
And this is all going to one team in a regular module Lua:
(echo 'return function(_)_[=['; sed -e 's/[][]=[][]/]=]_"\0"_[=[/g; s/<%/]=]_(/g; s/%>/)_[=[/g; s/<[?]/]=] /g; s/[?]>/ _[=[/g'; echo ']=] end') < template.tpl > template.lua
In fact, to run, you need to write another short function:
function template.print(data, args, callback) local callback = callback or print local function exec(data) if type(data) == "function" then local args = args or {} setmetatable(args, { __index = _G }) setfenv(data, args) data(exec) else callback(tostring(data)) end end exec(data) end
Installation

luarocks install template
