Question - Force reload of required lua script

[Soandso2]

Is there any way to force reload a required Lua?

Example:
foo.Lua contains a require("bar")

While foo.Lua is running, I make a change to bar.Lua. Is there anyway to force reload bar.Lua other than exiting and reloading foo.Lua?

Considering the lack of replies to the question, I presume the answer is "No, you cannot reload a required/included script by any other means than terminating the master script and running it again".

I think the deeper question is why would you need to do this. I can't imagine the need to completely restart a script unless it's not designed correctly. Does the script load something on start that you later need to reload for example? Then I would have a bind to reload that data rather than restart the script. XY problem here perhaps?

Master script is stand-alone and works as intended. Included script is an addition with code that you do not want to include in the master script - it is in development and you might be tweaking or rewriting parts. You make a change and you want to see if the change worked. It is not so much a "why would you want to", but a "is it at all possible to" question.

Yes, it's possible. I still contend this is an XY problem.

[CODE lang="Lua" title="This is our "working as intended script""]local mq = require("mq")
while true do
print("lua_one running...")
mq.delay(1000)
end[/CODE]

[CODE lang="Lua" title="This is our testing script that will stop and restart the first script"]local mq = require("mq")

print("lua_two running...")

print("stopping lua_one...")
mq.cmd("/Lua stop lua_one")
mq.delay(2000)

print("restarting lua_one...")
mq.cmd("/Lua run lua_one")[/CODE]

If you run these you'll see that script one will print out "lua_one running" every second...
Running the second one will stop, wait 2 seconds and then start (restart) the lua_one script.

i think you misunderstood the question coldblooded, he wants to know if you can make change to a required Lua file, and then have the main script reload the changed Lua file, remember required Lua files dont run, they just contain code, like the write.Lua by knightly.

 

[Coldblooded]

Oh, sorry! Thanks for the explanation Kaen.

Yes, it's still possible. Just "depends" on how much control you have over the main script file.

Basically, it works like this

[CODE lang="Lua" title="Original"]local mymodule = require("mymodule")


-- I hate my module, let me reload it!
package.loaded["mymodule"] = nil
mymodule = require("mymodule")[/CODE]

Untested, so not sure if this will work, but looks like something you're after...

Aaaha there we go. Thank you so very much.
