You can declare a global variable and use it like:
<?lua print(variable) ?>

Also you may want to call a external script:

<?lua dofile("script.lua") ?>

The variable declared inside the script will be avaible.

I made some modifications to the script to support NodeMCU 0.9.5 build 20150213.

New Features:

• Multiline lua code support (with start-tag "<?lua" and end-tag "?>")
• Url Parameter (url parameter are in a lua table "get". For example: get["gpio"])

I added some easy examples to the zip.

I have problems with random hard resets when the script is running.
Can anybody confirm that? (maybe there is a problem with my ESP8266 or power supply)

Working fine for me with latest firmware version, no random restarts so far.
Found two problems:

Anything on the same line before and after <?lua ?> is not sent to the response
If any query string is sent empty there is an error and a restart

Added code to github with a example form, where you can simulate both erros: https://github.com/andrempo/lhttpd

Not working for me with files, larger 2,5k.
