zclsyntax: Generate "Variables" implementations for all Expressions The implementation of Variables will be identical for every Expression implementation since we just wrap our AST-walk-based "Variables" function to do the work. Rather than manually copy-pasting the declaration for each expression type, instead we'll generate this programmatically using "go generate". This will need to be re-run each time a new expression node type is added, in order to make it actually implement the Expression interface. 2017-05-24 15:50:44 +00:00			`package zclsyntax`

zclsyntax: start of a ragel-based scanner Using Ragel here because the scanner is going to be somewhat complex due to the need to switch back and forth between normal and template states, etc. This should be easier to maintain than a hand-written scanner, while ragel gives us the extra features we need to implement things that would normally be too complex for a "regular" scanner generator. 2017-05-28 02:01:43 +00:00			`//go:generate ragel -Z scan_token.rl`
