fix: gracefully handle unknown -D options in verso-literate - #969

When `lake lint` runs, it passes linter overrides to downstream executables by prefixing the options with `weak.` (e.g., `-Dweak.linter.style.openClassical=true`). Previously, `parseDOption` strictly relied on `getOptionDecl name` to find the expected type for an option. If the option was unknown (e.g. because of the `weak.` prefix or because it hasn't been registered yet), `getOptionDecl` threw an internal exception, causing `verso-literate` to crash. This patch mirrors the behavior of `setConfigOption` in core Lean (`src/Lean/Shell.lean`). By using `(← getOptionDecls).find? name`, we can check if the option exists. If it does, we parse it according to its type. If it doesn't, we gracefully fall back to storing it as a string in the `Options` map and defer validation to the elaborator, preventing the crash.

Thanks for the PR, and sorry for the slow response. From what I can see, we also need to run Thanks again! |
