Localmode

What does “localmode=true” means?

I see it in some function attributes definition like Lucee/Application.cfc at master · lucee/Lucee · GitHub

Example :

function getPackages() localmode=true {…}

According to documentation ( “<cffunction> :: Lucee Documentation” ) it should be a string value with accepted values such as “classic” or “modern” only.

Please advise.

Thank you

it automatically assigns variables in a function to the local scope

Thanks for reply, yes that what it says in documentation, it just was strange to see attribute value TRUE.

But I believe it still better from performance point to use scope like arguments, variables … ?

yes it is always better, you can see in the debugging if you enable implicit variable access

that said, it’s not going to make so much of a difference unless the code is called a lot,

localmode=“modern” is also about avoiding overwriting other variables outside the function which can cause strange and hard to debug errors

My answer to the original question:

localmode=true is equivalent to localmode="modern".

However, in the referenced core/src/main/cfml/context/doc/Application.cfc I see another undocumented value for localmode:

this.localmode="update";

What is the purpose of "update"?

it’s just an alias for classic
