Was curious if there are any options for having a lua-script be triggered when certain jobs are completed. Basically, looking for something like the dfhack.onStateChange but for jobs. Alternatively, if there is any way of triggering for lua-scripts when the job_next_id advances.

As I currently understand it, there are two options:
1.) Have a lua-script with a dfhack.timeout of 1 "frames" and have it check the existing job list for the job_type in question. My concern here is that this could be process intensive as it would be checking the job list every frame.

2.) Use a Ruby script similar to autounsuspend.rb which appears to check the job list for suspended buildings before unsuspending them if they meet certain criteria. (Seems to use df.onupdate_register as a trigger but not sure if it works with lua code)

Open to suggestions or thoughts on the matter.

Troll question: is Ruby superior to Lua or is this just a case of me being dumb?

There is already an event manager trigger for onJobInitiated and onJobCompleted. For examples of other scripts that use the event manager triggers you can look at modtools/interaction-trigger and modtools/item-trigger

EDIT: Both of which are lua scripts

Thank you. That is exactly what I was looking for. Didn't see those used in any of the built in-scripts and wasn't sure where else to look. Will give it a few tries and see what I can do with it.

Really out of my depth when it comes to trying to use environment functions and having a hard timing understanding what I am doing wrong compared to what others have done. For example, the current problem I am having is that the below code throws an error saying "attempt to index a function (field 'onJobInitiated')

Code: [Select]

local ev=require 'plugins.eventful'

ev.onJobInitiated.test = function(JOB)
if enabled then
print("Job started!")
end
end

ev.enableEvent(ev.eventType.JOB_INITIATED, 0)
According to examples such as item-trigger.lua, innteraction-trigger.lua, etc there should be something there, but I do not understand what the rules are or what I am missing (removing the .test causes it to run without error but it does not seem to recognize when new jobs are started).

Any help would be appreciated.

What version of DFHack are you using? and how are you doing this test? I just copied that code into a script and it worked for me. Where do you set what enabled is?

Using DFHack 0.44.12-r2.

The enabled script is a tidbit that I should have removed, sorry.

Also, apparently functions do not like being called multiple times while previous iterations are running. I had been making changes to the code and re-running it without exiting DF between attempts, so there must have been hold-overs that didn't like me doing that. Bad habit and lack of foresight.

Thanks for the help and enjoy the laugh.

Ah yes, if you had done ev.onJobInitiated = function blah and then tried to do ev.onJobInitiated.test = function blah that would explain the error of not being able to index a function

Worth noting that restarting DFHack is usually overkill. In this case, you might be able to get by with "reload eventful" at the console and/or "reload('plugins.eventful')" in Lua. For most scripts in general (if they're not messing with global DFHack state outside of their own state), clearing or deleting dfhack.script_environment('script_name') will work.
