Lua: Executing a string and storing the output of the command in a variable
But I want the function loadstring somehow return the result in string form that may be assigned to a string variable later to use further, what it returns is a function. Below code is an example:
ret = assert(loadstring(str_cmd))()
ret is a function:(
How can I get the REPL/loadstring output in string form?
Best How To :
If all output from
str_cmd comes from calls to
print before loading
str_cmd to save all output in a table. After running
str_cmd, use the table in
table.concat for instance.
Instead of redefining
print you can provide an environment to run
str_cmd in. You'll probably need to make that environment inherit from the global environment.
