Parser and Lexer — How to Create a Compiler part 1/5 — Converting text into an Abstract Syntax Tree
In this tool-assisted education video I create a parser in C++ for a B-like programming language using GNU Bison. For the lexicographical analysis, a lexer is generated using re2c.
This is part of a multi-episode series. In the next video, we will focus on optimization.

[9:35 PM] Bisqwit: Now uploading to YouTube. Within about 24 hours I will know if the rogue AI at YouTube slams the “limited or no advertising" stamp into it, or not. Actually, I only know if it does so *when* it does it. Then, I need to wait an additional 25 hours for YouTube staff to manually review it and clear the flag. If the flag does not appear, then it is possible that the bot just has not scanned it yet and I need to wait longer. Premature publication could mean that the bot will mark it after it has already been published, and then I will not receive any revenue for the first spike of views. It used to be 18 hours (since uploading that the bot does its evil deeds), but nowadays YT recommends waiting just 3 hours. We will see, we will see.
