Hello

I'd like to run small Lua web scripts on an ARM9E appliance running Debian. It looks like Mongoose is the simplest way, but the relevant page about Lua in the Overview section is currently 404.

Could someone show me how to compile and configure Mongoose to run a "Hello, world!" Lua script securely on that platform?

Thank you.

Fixed broken link, thanks for pointing it out.
The easiest way to compile mongoose on Linux with Lua support is
to close git tree, then

cd /path/to/mongoose/repo/build
make mongoose-lua

Thanks Sergey.

The tarball from the Downloads section doesn't seem to include the mongoose-lua Makefile, and I don't know Git.

To avoid having to go through a whole tutorial just for this, is there a howto that shows how to compile Mongoose with support for Lua (and SQLite)?

Thank you.

Thanks, it compiled and runs OK.

BTW, the page is 404 again:

I assume Mongoose includes the Lua interpreter, so I don't need to use the " -cgi_interpreter" switch. However, after adding the following "test.lp" file and launching "mongoose-lua -cgi_pattern **.lp", the browser displays the source code instead of showing the output:

<? print('HTTP/1.0 200 OK\r\nContent-Type: text/html\r\n\r\n') ?>
<html>
<body>
<p>
  <span>Today is:</span>
  <? mg.write(os.date("%A")) ?>
</p>
</body>
</html>

With newest sources, use .mg.lua extension. Don't specify -cgi_interpreter.

Thanks, the sample could run the first lines (mg.write).

However, no SQLite database is created, and "./mongoose-lua -error_log_file mongoose.error.log" doesn't create a log file so I could check why:

/tmp/mongoose/build# cat test.mg.lua


mg.write('HTTP/1.0 200 OK\r\n', 'Content-Type: text/plain\r\n', '\r\n')


mg.write(os.date("%A"))


local db = sqlite3.open('requests.db')


db:exec([[


  CREATE TABLE IF NOT EXISTS requests (


    id INTEGER PRIMARY KEY AUTOINCREMENT,


    timestamp NOT NULL,


    method NOT NULL,


    uri NOT NULL,


    addr


  );


]])


db:close()

Do I need to recompile Mongoose with a different Makefile than "mongoose-lua" to include both the Lua interpreter and the SQLite DBMS?

Also, is http://cesanta.com/#docs,Mongoose.md the only documentation available at this time?

Ah, please use another target to build with sqlite:

$ make mongoose-lua-sqlite

Hmm, could you elaborate please? There are many pages of documentation on various topics,
listed on the left hand side. What exactly are you looking for?
