I’ve been designing a new lightweight markup language for the past few months, and I have decided to take this approach for things like typographic punctuation: rather than the markup language engine embedding fallible heuristics (turning ' into ‘ or ’, based on the natural language’s usage) or annoying ligatures (e.g. TeX has -- → –, --- → —, ` → ‘ and ' → ’), I will provide a linter that provides flexible rules for such transformations and the ability to perform in-place replacement. This linter will also be able to perform source autoformatting of various kinds, e.g. visual alignment of list indentation and table columns, and it’ll be hooked into LSP so direct text editor integration is possible.
