One interesting consequence of the rise of LLMs: there's more demand for tools that handle untrusted input. Arbitrary HTML+JS can be safely run in a browser. Lean can check an arbitrary proof. These work really well with an LLM that can be wrong, but sometimes gives exactly what you want. Are there other tools in this family?

In LSP, a position is represented as a line number and a column offset (in Unicode code units): https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#position This is pretty elegant. You'll get the correct line regardless of encoding bugs, and the editor already knows the line number so it's cheap to compute.

An ad hoc, informally-specified, bug-ridden, slow implementation of half of a text adventure game -- or as I like to call it, a compiler.
