# compiler

Anyone know what docs to read to get started with understanding how kotlin compilation works? I heard that it was a bit complicated and wanted to get a feel for what was going on to see if there's anything I can do about speeding it up over the next few months.

Self advertising myself, I also had a talk about the Kotlin compiler recently 🙂

It is more focused on plugins, but one chapter is completely about compilation processes.

Also note that there are ongoing efforts by JB and Google teams to speed it up, they are rewriting huge parts of compiler and promising quite nice perf boost 🙂

Thanks for the info. I'll give it all a look-over.

Since this has been pinned to the channel as newbie help, I would like to point also to the great article series by @bnorm https://blog.bnorm.dev/writing-your-second-compiler-plugin-part-1

[shikasd]

Not sure I have the sources, will check 🙂
Probably better to publish transcript later
