expand-specials clj

(expand-specials pattern)

literal? clj

(literal? t)

Is a given simple-type a literal/non-special?

match-alt clj

(match-alt ctx pattern)

match-binding clj

(match-binding ctx bind form)

Pattern must be a symbol in ?x style already.

match-optional clj

(match-optional ctx pattern)

match-plus clj

(match-plus ctx pattern)

match-plus-rest clj

(match-plus-rest ctx pattern)

match-pred clj

(match-pred ctx bind form pred)

match-single clj

(match-single ctx items)

Checks multiple single-element values at once.

Instead of generating a big and like in v1, this rebinds ctx and the children-form for each pattern, returning nil if one of the patterns doesn't match and somewhat short-circuiting the rest of the checks.

Relies on the output of the single-element pattern functions and expects them to return the ctx object iff there's a match.

match-star clj

(match-star ctx pattern)

match-star-rest clj

(match-star-rest ctx pattern)

non-coll? clj

(non-coll? t)

Is a given simple-type a non-collection?

pattern clj macro

(pattern pattern)

Parse a provided pattern s-expression into a function that checks each element and sub-element of the form as a whole predicate. Makes semi-smart decisions about using let-bindings to avoid re-accessing the same value multiple times, adding type hints to rely on interop, and handles the complexities of the pattern DLS.

Returns a map or nil. If the provided pattern uses bindings, the map will have the bindings as keys.

read-dispatch clj

(read-dispatch pattern)

(read-dispatch _ctx pattern _form)

Same as [[simple-type]] except that :symbol and :list provide hints about their contents. Can be skipped by adding the metadata :splint/lit.

read-dispatch-symbol clj

(read-dispatch-symbol sym)

Return the special type of a special symbol, or :symbol if normal.

read-form clj multimethod

(read-form ctx pattern form)

Implementation of the main logic of pattern. Requires form and ctx symbols to be provided to allow for recursion.

seq-match clj macro

(seq-match ctx pattern form)

seq-match-step clj

(seq-match-step ctx form fns)

Inspired by segment-matcher from pangloss/pattern.

simple-seq-match clj

(simple-seq-match ctx pattern form)

special? clj

variable-seq-match clj

(variable-seq-match ctx pattern form)
