Installing Orbit and its requirements

luciano de souza-2
Hello all,

I tried to run an example of Orbit application. I have a very short
knowledge about web servers, so I try to follow the tips I have found.

First of all, I have installed everything:

$ sudo apt-get install lua5.2
$ cd /home/luciano/Downloads/luarocks
$ sudo chmod +x configure
$ sudo ./configure
$ sudo make build
$ sudo make install
$ sudo make bootstrapp
$ sudo luarocks install orbit
$ sudo luarocks install xavante
$ sudo luarocks install wsapi-xavante

So I regard this example:

-- x.lua
#!/usr/bin/env wsapi.cgi

local orbit = require('orbit')

module('hello', package.seeall, orbit.new)

function index(web)
return Render_Index()
end

hello:dispatch_get(index, '/index')

function Render_Index()
return [[
<html>
<title>Um teste</title>
<body>
<P> Eis aqui um teste. </p>
</body>
</html>]]
end

orbit.htmlify(hello, "render_.+")

return M

I run:
$ lua x.lua

and I got this error:

lua: /usr/local/share/lua/5.2/orbit.lua:9: attempt to call local
'setfenv' (a nil value)
stack traceback:
        /usr/local/share/lua/5.2/orbit.lua:9: in main chunk
        [C]: in function 'require'
        x.lua:3: in main chunk
        [C]: in ?

What's wrong?

In fact, my few knowledges can't detect the error.

I thanky you very much for any help.

Best regards,

Orbit only supports Lua 5.1. Hope this helps.

Re: Installing Orbit and its requirements

Coming back to Lua 5.1, the error disappear. But, I was not able to
launch the script! It seems to be very close.

No errors, but no results. Doing "$ lua app.lua" at the terminal,
nothing is writen, not is returned...

But, actually, I didnt no either what URL to call! What'is the port?
Sould I call as "localhost:3000"?

The module is:

-- hello.lua
#!/usr/bin/env wsapi.cgi

local orbit = require('orbit')

module('hello', package.seeall, orbit.new)

function index(web)
return render_index()
end

hello:dispatch_get(index, '/index')

function render_index()
return [[
<html>
<title>Hello world</title>
<body>
<P> This is a hello world page</p>
</body>
</html>]]
end

orbit.htmlify(hello, "render_.+")

return M

The launcher is:
#!/usr/bin/env wsapi.cgi

return require('hello')

Re: Installing Orbit and its requirements

Ryan Pusztai

You need a web server. Just running the app doesn't work. You need to use apache2 (https://luanova.org/setting-orbit-to-use-apache2/) or Xavante (luarocks install wsapi-xavante).

I highly recommend Xavante. It installs easily and then you just run `$ wsapi app.lua`. I believe it defaults to port 8080. See the help on `wsapi --help` for more details.

(I am not in front of a PC right now so some of the commands might be off by a little bit.)

Hope this helps.

Re: Installing Orbit and its requirements

luciano de souza-2
I had already installed Xavante. As I didn't know how Orbit works, I
imagined it internally called Xavante. So I imagined an embeded
server.

This things are still confused for me. I found a brief tip of Xavante.
It descrives the configuration, but I could not understand how to run
it and where to place the files.

Well, I am better than I was.

Re: Installing Orbit and its requirements

luciano de souza-2
Reading the Xavante manual, I found a suggestion of a configuration file:

--server.lua
local hfile = require "xavante.filehandler"
local hcgi = require "xavante.cgiluahandler"
local hredir = require "xavante.redirecthandler"

local xavante = require "xavante"

-- Define here where Xavante HTTP documents scripts are located
local webDir = XAVANTE_WEB

local simplerules = {

    { -- URI remapping example
      match = "^[^%./]*/$",
      with = hredir,
      params = {"index.lp"}
    },

    { -- cgiluahandler example
      match = {"%.lp$", "%.lp/.*$", "%.lua$", "%.lua/.*$" },
      with = hcgi.makeHandler (webDir)
    },

    { -- filehandler example
      match = ".",
      with = hfile,
      params = {baseDir = webDir}
    },
}

xavante.HTTP{
    server = {host = "*", port = 8080},

    defaultHost = {
    rules = simplerules
    },
}

Note the use of webDir both to set the base directory for the file
handler and for the CGILua scripts. These paths should contain the
desired directories in your structure.

To use virtual hosts with Xavante, the call to xavante.HTTP would be
changed to something like

xavante.HTTP{
    server = {host = "*", port = 8080},

    defaultHost = {},

    virtualhosts = {
        ["www.sitename.com"] = simplerules
    }
}

It's not so easy to understand. I imagine "match" is used as the
rewrite rules of Apache.

XAVANTE_WEB seems to be a constant, probably "/", the current
directory where "server.lua" is placed.

I don't understand exactly the sense of cgiluahandler and filehandler.

But the most obscure part of the manual is about "xavante.start". If I
am using Xavante as  a module, so I should call "xavante.start"
passing a "chck function".

I am using as a module? I am not sure! But as I have a
"require('xavante')", I believe yes.

"Check function"? the manual does not present an example... I don't
have any ideia what it is.

It would be wonderful if Xavante came with a standard configuration.
In PHP, with a simple "php --runserver", the server is raised.

As long as the time goes by, the experience increases and all the
parameters of the server will be understood. But at the first time,
it's really very complex!

Re: Installing Orbit and its requirements

Ryan Pusztai

Hi,

I don't *ever* mess with Xavante directly like that. I use the launcher (wsapi or orbit) installed during the wsapi-xavante rock. Just supply '.' for current working directory, or where ever your website source is (e.g. /var/xavante/<app-files>).

Have you read the Orbit docs (http://keplerproject.github.io/orbit/example.html). There is a good tutorial and it shows how the pieces fit together.

If you are looking for an alternative that does run its own webserver I suggest looking at Turbo.lua (http://turbolua.org).
