I'm having macro troubles with a DSL I'm writing. I have a macro that looks
something like this:
(define-syntax (query stx)
(let ([lines (cdr (syntax->datum stx))])
(define lines-syntax-tree (parse-to-tree lines))
(datum->syntax stx lines-syntax-tree)))
So something like
(query ...linear series of s-expressions containing non-nested code...)
is transformed into (...hierarchical code in tree form...).
But what I really want is
(run-query '(...code in tree form...))
The code that I'd like quoted and passed to run-query has a number of
macros I wrote that also need expanding. My problem is that all of my
attempts to write a macro that results in run-query being passed a list of
code to execute blocks the expansion of the passed code. Basically, I want
to expand 'lines-syntax-tree' before I quote it and generate an expansion
including run-query.
For instance, this obviously doesn't work:
(define-syntax (query stx)
(let ([lines (cdr (syntax->datum stx))])
(define lines-syntax-tree (parse-to-tree lines))
(define q (list 'run-query (quote lines-syntax-tree)))
(datum->syntax stx q)))
I'm sure I'm missing something silly, but I'd appreciate any help. I should
probably read https://docs.racket-lang.org/reference/syntax-model.html, but
it is going to take me some time to grok that.
Thanks,
Jonathan
