Global vars 'undefined' in local scope after running any program.

Global vars 'undefined' in local scope after running any program.

What version of kOS are you on because this {set time to "Time for coffee".} and this {set constant to lex("pi", 3.5).} should be throwing a compile time errors.

I'm running v1.4.0.0

I just realized i had config:clobberbuiltins set to true, so with that off the two points you mentioned no longer hold. The rest still applies though.

Good to know I had to ask after the version because we have had a few people who have for one reason or another been on older versions without knowing it and updating fixed the issue.

I was able to reproduce the error on my end though my test cases ended up looking like this:

log "" to "foo.ks".
run foo. { global x is 1. print defined(x). } print defined(x).

and

//used the foo.ks from above
run foo. {print defined(time).} print defined(time).

and

log "global y is 2." to "bar.ks".
run bar. { print defined(y). } print defined(y).

In my tests the log was only run once and restarts occurred between attempts to remove the added global vars.
Both cases ended up printing

false
true

when they should be printing

true
true

I also tested running the tests as files and not commands typed into the terminal and got the expected result.
At a guess this is down to the terminal execution environment is in a strange state after run command and not fully settled until you have a prompt again.

Actually even with clobberbuiltins enabled this

run foo. {set time to "Time for coffee".}
print time.

should still not print Time for coffee but rather some TIMESTAMP(...), meaning in this setup it does not clobber locally but rather overrides globally.
So it does behave fundamentally different than without running a program first like

{set time to "Time for tea".}
print time.

which prints TIMESTAMP(...) as expected.

[nuggreat]

the abnormal behavior in this case

{set time to "Time for tea".}
print time.

is that it prints TIMESTAMP(...) as the set should be clobbering time in the global scope as without a LOCAL TIME TO ... the SET defaults global.

Which some what counterintuitively means that means that

run foo. {set time to "Time for coffee".}
print time.

is behaving correctly and the other case does not. But as both cases involve clobbering built ins the behavior will always be rather abnormal as it was never intended that you could clobber built ins hence the default setting to prevent it.
