Debuging lua application using ZeroBraneStudio with own lua interpreter

I would like to debug my application using ZeroBraneStudio 1.4 with my own lua interpreter (5.1) on Windows 7.

I set the interpreter in user.lua as

path.lua = '<PATH_OWN_INTERPRETER>'

my_app.lua has the following as the first line

package.path = package.path .. ';../CommonScripts/?.lua'
print(package.path)

which prints

;.\?.lua;<PATH_OWN_INTERPRETER>\lua\?.lua;<PATH_OWN_INTERPRETER>\lua\?\init.lua;<PATH_OWN_INTERPRETER>\?.lua;<PATH_OWN_INTERPRETER>\?\init.lua;./?.lua;./?/init.lua;./lua/?.lua;./lua/?/init.lua;<PATH_ZBS>\lualibs/?/?.lua;<PATH_ZBS>\lualibs/?.lua;<PATH_ZBS>\lualibs/?/?/init.lua;<PATH_ZBS>\lualibs/?/init.lua;../CommonScripts/?.lua

When I start debugging, the following error occurs.

<PATH_ZBS>\lualibs/ssl.lua:19: module 'ssl.x509' not found:
    no field package.preload['ssl.x509']
    no file '.\ssl\x509.lua'

I have the following line in Class2.lua:36

local https = require'ssl.https'

It seems that the ZBS is mixing up the directories of built in Lua interpreter with the one that I would like to use.

How can I prevent this?

Solution

  • Apparently when the lua path in user.lua is set as 

    path.lua = '<PATH_OWN_INTERPRETER>'

    It is expanded by ZeroBrane Studio to

    <PATH_OWN_INTERPRETER>\lua\?.lua;
<PATH_OWN_INTERPRETER>\lua\?\init.lua;
<PATH_OWN_INTERPRETER>\?.lua;
<PATH_OWN_INTERPRETER>\?\init.lua;

    In my own interpreter, ssl is located at <PATH_OWN_INTERPRETER>\lua\ssl\ssl.lua with is not included in the list above.

    So, my solution was to define LUA_PATH as environmental variables so that I get

    <PATH_OWN_INTERPRETER>/?.lua;
<PATH_OWN_INTERPRETER>/lua/?.lua;
<PATH_OWN_INTERPRETER>/lua/?/?.lua;

    in the path.
