POC for New Breve Idea
View A_Blitz_FSharp
Breve was designed as a backwards-compatible Blitz replacement that does safe context-aware sanitization.
The current architecture uses Blitz's parser frontend + Latte as a context-aware backend to achieve this goal. This was because I figured writing a context-aware HTML+macro parser was harder than re-implementing Blitz's logic flows (blocks, variable lookups, partial templates, etc.) in Latte.
As it turns out, reimplementing logic is a difficult problem. An alternate solution would be to write our own Blitz-compatible frontend that just adds context-aware output and delegates to Blitz for the logic implementation. This is a Proof of concept that shows it isn't that bad in a language that makes writing parsers easy.
