I have a bunch of lua scripts that have lot of code in common. What are some of the ways once can reduce code duplication? 

I tried using the require keyword, and even tried calling evalsha from my lua scripts, but those approaches did not work. 

When I use require, I get the following error:
@enable_strict_lua:15: user_script:31: Script attempted to access nonexistent global variable 'require'

When I registered the common script and tried using the sha1 in an evalsha command from within my lua script, I get the error message :
This Redis command is not allowed from scripts

All I am looking to do is avoid code duplication in the redis lua scripts and improve maintainability.  Ideas/suggestions appreciated. 

Thanks,
-Ambar

Hi,

You can create a method/function for common code, in your lua script and call them where-ever required.

Regards
Narendra

Thanks, but how do you share this code between various .lua scripts in Redis?
