I need to find any list of all the Openresty libraries that I can use 
as in 
local mysql = require "resty.mysql"
as well a general LUA programming boom as it applies to Openresty.  I already saw many generic videos about LUA.
For example, I cannot figure out how to obtain the same functionality of  "continue" in a loop, as found in every other language. I cannot figure out how can I call utility like awk or grep, etc, from inside Openresty-LUA, and send parameters, receive output to a variable. Also, I would like to find a library to convert a database result set to HTML where I can tell exactly how I want the conversion to be done.
Thanks in advance

Use 
{*expression*} in your html template.

{*expression*} -> writes result of expression

I am trying use this gsub
string:gsub(',',''):gsub("PRCT","%")
basically, I need to eliminate all commas from string and also replace "PRCT" for "%",
but the second part does not work.
What am I doing wrong?

use %% when you need % as % is a marker

I must be blind where is the documentation for that?
What kind of information can I use on the right side?
Is it possible to combine both replacements in one?
Thanks in advance.

The Lua book (page 92) gives that info. But a quick google search yielded


I don't think you can combine them

Can you give details about the Lua Book whose page 92 has this information?
There are many LUA books. I want to order the one.
Thanks in advance.

Question: what library should I use for this: 
I want to retrieve a result set from my database, using resty.mysql, but then I need to convert it to an HTML table, as is, no changes, just get it and send it forward to the client.
What library should I use?
For example, I do a "select * from table", get the result into a variable, and need to convert it to <table>.....</table>.
Is this possible at all?

Thanks in advance

I am already using it, but as raw. 
I build my HTML table at the database. Suppose I don't do that and do an arbitrary select statement on any MySQL table, so I get from LUA:
res[1]["field1","field2"]...
how can translate that into a perfectly formed HTMAL table?
I use resty.mysql for the database
what do I have to add in the template?

The book I am referring to is by the original developers of Lua. A bit dense but a good reference
