Hi Tiago what version of the Kotlin compiler are you using We have pending updating Arrow Analysis to the new K2 compiler frontend Also heads up Arrow Analysis is highlyexperimental

Tiago · Answer

hey Raul thanks for your quick reply Yeah want to try it on a personal project slightly smiling face I am using the 1 8 10 kotlin version

raulraja · Answer

Arrow Analysis is currently coupled to `1 6 21` <https github com arrow kt arrow analysis blob main gradle projects libs versions toml L9>

raulraja · Answer

We need to update it to FIR to 1 8 20 Beta at least but that requires an entire rewrite of the tree interfaces which are currently mapped to the old kotlin frontend

raulraja · Answer

I d probably have to do that unless someone picks it up and I m currently swamped with work at least until the summer But I plan to start adapting the tree to FIR when 1 9 2 0 comes stable

Tiago · Answer

weird I created a new project using the 1 8 20 Beta and it worked the problem was my old project sweat smile

Tiago · Answer

but anyway I wonder if I could contribute a little with this

raulraja · Answer

it may work in some cases but since the Kotlin compiler makes no guarantees of its public api changing in some others it may fail

raulraja · Answer

we don t restrict it
