Parse/process options to control addition of ';' and '\n'

[ShayRubach]

Hey. I have an input

var x = y

that is simply going through parse_js -> process_js and its output is

var x = y;\n

Which options control this formatting? I went over swc::config::Options and its inner members and didn't find any hints about ; or \n in particular.
I basically want swc to make zero optimizations/changes/additions that are not invoked by my visitor during transformation.
Thanks.

There's no option to do so.

I see.
Could you direct me to the code who appends them? Maybe I can PR it if in my free time 😄
Thanks for the quick response.

I think is emit by

swc/crates/swc_ecma_codegen/src/macros.rs
