any-symbol?clj/s
(any-symbol? x)true if x is a symbol beginning with _.
true if x is a symbol beginning with _.
childrenclj/smultimethod
(children node)Return a sequence of all subnodes of node.
Return a sequence of all subnodes of node.
defsyntaxclj/s≠macro
(defsyntax name docstring? meta? arglist & body)(defsyntax &form &env & args)EXPERIMENTAL Like defn but for defining new pattern syntax by extending the parser. When parsing, if a seq is encountered starting with a symbol which can be resolved to the created var then the tail of the seq is applied to the var and the result is parsed.
Example
(defsyntax re [regex] `(~'pred (fn [s#] (and (string? s#) (re-matches ~regex s#)))))
(require '[meander.match.alpha :as r.match])
(r.match "elf" (re #"[a-z]+") :okay!) ;; => :okay
