You can "capture" symbols from the surrounding context, making them
available to the body of your macros, the "tilde tick trick" is what
you're looking for there:
(defmacro deftransducer
[body]
`(fn [reducing-fn#]
(fn
([] (reducing-fn#))
ount/start args)
(netty/wait-for-close server/http))

Good morning (at least from my part of the globe),
I spent a good chunk of time last night wondering why this chunk
of code
kept exiting about a minute after being
/either (p/attempt p) (p/always default-value)))
(p/defparser p []
(p/let- [h (optional (helloParser) nil)
w (worldParser)]
(p/always [h w])))
Hope that helps.

You could use `lazy-seq`. Something like this:

Can you provide the code for this?
Certainly.
The parser's current source position is stored in the InputState
record's `pos` field. That field is a SourcePos record consisting of
the current line and column

Ok. Thanks for the answer.
Is there any way to get the line and column?
The Parsatron doesn't have any builtin facilities for extracting line
numbers from tokens, you'd have to keep track of the number of newline
for:
(defparser arr []
(between (char LPAREN) (tok (char RPAREN))
(many (attempt (tok (array-item))
Cheers,
