PowerShell+ 2019 - Parselmouth - bending the PowerShell language by Mathias Jessen

I want to introduce the audience to the high-level design of the tokenizer, parser and compiler in PowerShell Core, and then take it a step further - during the course of the presentation we're going to introduce and implement a whole new operator in PowerShell Only the first few minutes will be slides and introduction, the remaining time we'll use to dig into the PowerShell Core source code, live-code our intended changes with input from the audience, and finally compile and demo our new out-of-the-blue language feature. PowerShell Summit videos are recorded on a "best effort" basis. We use a room mic to capture as much room audio as possible, with an emphasis on capturing the speaker. Our recordings are made in a way that minimizes overhead for our speakers and interruptions to our live audience. These recordings are meant to preserve the presentations' information for posterity, and are not intended to be a substitute for attending the Summit in person. These recordings are not intended as professional video training products. We hope you find these videos useful - the equipment used to record these was purchased using generous donations from members of the PowerShell community.
