[misiek08]

Fixes #358

[KEINOS]

Cool! 👍

I think we should fix the script comment as well.

tengo/stdlib/srcmod_enum.tengo

Lines 74 to 77 in 09240a1

	// filter iterates over elements of `x`, returning an array of all elements `fn`
	// returns truthy for. `fn` is invoked with two arguments: `key` and `value`.
	// `key` is an int index if `x` is array. `key` is a string key if `x` is map.
	// It returns undefined if `x` is not enumerable.

Will do this tomorrow, because I need to run/regenerate go file with this source and I need PC to do this :)

[misiek08]

Sorry, took much longer because of some unexpected additional work I had to do.

@d5
This change seems to be OK but doesn't stdlib/source_modules.go file be updated via go generate by the maintainers?

[KEINOS]

LGTM to the changes though.

[d5]

I think this PR includes the output of go generate as well, right? @misiek08

[misiek08]

I ran go run gensrcmods.go

[KEINOS]

@misiek08

I ran go run gensrcmods.go

Ah, I got it.

That file should be triggered via go generate ./... defined in stdlib/stdlib.go's header, I think.
They will be overwritten anyway, but the fewer files to review, the better, right?

@d5

I think it's good to go. What do you think?
