The dir variable here is unnecessary, you can just have return statements in the branches

We also cannot assume data home is at /home/$USER/.local/share. See resolveLogDirectory on how to properly handle this

I feel like the previous way of re-assigning to dir is more readable. There's also a missing return statement, and XDG_DATA_HOME is not being handled

Suggested change

val dir = System.getenv("SLIMEVR_SOCKET_DIR")

if (dir != null) return dir

if (currentPlatform == LINUX) {

dir = System.getenv("XDG_RUNTIME_DIR")

if (dir != null) return dir

val isPressureVessel = System.getenv("PRESSURE_VESSEL_RUNTIME")?.isNotEmpty()

if (isPressureVessel == true) {

System.getenv("HOME")?.let { Path(it, ".local", "share", "dev.slimevr.SlimeVR") }

} else {

val runtimeDir = System.getenv("XDG_RUNTIME_DIR")

return if (!runtimeDir.isNullOrBlank()) {

runtimeDir

} else {

System.getProperty("java.io.tmpdir")

}

}

var dir = System.getenv("SLIMEVR_SOCKET_DIR")

if (dir != null) return dir

if (currentPlatform == LINUX) {

val isPressureVessel = System.getenv("PRESSURE_VESSEL_RUNTIME")?.isNotEmpty() == true

if (isPressureVessel) {

dir = System.getenv("XDG_DATA_HOME")?.let { Path(it, CONFIG_IDENTIFIER) }

?: System.getenv("HOME")?.let { Path(it, ".local", "share", CONFIG_IDENTIFIER) }

if (dir != null) return dir

}

dir = System.getenv("XDG_RUNTIME_DIR")

if (dir != null) return dir
