I have a search template of $Before$.$MethodCall$($Parameter$) , problem is..it matches on <http://log.info|log.info> { } as well as <http://log.info|log.info> (), how can i get it to not match on lambda? I set complete match but it still doesn't listen to me, i want it to take the parentheses as is

[Roukanken]

remember that's it is a structural search, and therefore it searches based on structure of the syntax tree.

Eg, from AST view, <http://log.info|log.info> { } is same as <http://log.info|log.info>({ }) - and { } gets matched to your $Parameter$

[Roukanken]

how to solve it hmmm... I guess only way is to limit what can get matched as parameter.
Limiting its type should help you I guess?

[sreich]

@Roukanken so, that's the part that confuses me..if you look at the builtin kotlin ones, you get { $Parameter$ } , this matches <http://log.info|log.info> {} only

[sreich]

but it seems like if you surround it with other stuff, maybe...it doesn't seem to work the same

[sreich]

if the AST thing you mention were true, it should have matched on my braces, in my original test case, as it does for the builtin example

[Roukanken]

remember that func { } is just a syntax sugar for func( { } ) they have the exact same meaning

which means ASTs look something like this:
• func { } AST is:
◦ call a method (taken from whatever is func ) and give it as parameters:
▪︎ lambda function
• func({ }) AST is same ↑
• func { $parameter$ } is:
◦ call a method (taken from whatever is func ) and give it as parameters:
▪︎ lambda function
• of which content is "return `$parameter$`"

yeah i get that part, but i'm saying that it is matching on {} which matches log.debug {}, and not log.debug() . so it definitely treats it differently

[Roukanken]

okay, I took out the big guns, and surprisingly there is a difference between 1st and 2nd
This should be the tree JB is operating on

[sreich]

hm interesting. thank you. shall i raise a youtrack issue?

[Roukanken]

I'm reasonably sure this is an intended behaviour (as it would make more sense)
but yeah, this basically stops you from matching what you want

also fun is that <http://log.info|log.info> { $x$ } matches only the first one
but <http://log.info|log.info>({ $x$ }) matches both

[sreich]

haha right?

[sreich]

it's hilarious becuase it's matching everything i don't want. i just want to match parentheses 😂

[sreich]

@Roukanken btw how do you view the AST like that? also, nice color scheme

[Roukanken]

It's a plugin (PSI viewer I think?) mostly meant for coding plugins to manipulate code. It shows internal tree of code

[sreich]

okay, cool
