basilisp.walk

Generic data structure walkers.

Support for all builtin data structures and types is included by default. Users can add support for custom data types by extending the IWalkable protocol.

protocolIWalkable

fn (walk* this inner outer)

Walk the data structure applying inner to each element of the data structure, if any, and then applying outer to the result.

fn (keywordize-keys form)

Recursively walk form, transforming string keys into keywords in any maps.

fn (macroexpand-all form)

Recursively macroexpand all eligible forms contained in form.

fn (postwalk f form)

Walk form using depth-first, post-order traversal, applying f to each form and replacing form with its result.

All built in data structures are supported.

Lazy sequences will be completely consumed (and thus may not be infinite).

fn (postwalk-demo form)

Print each element as it is walked as by :lpy:fn`postwalk`.

fn (postwalk-replace replacements form)

Recursively walk through form as by postwalk, replacing elements appearing as keys in the map replacements with the corresponding values.

fn (prewalk f form)

Walk form using depth-first, pre-order traversal, applying f to each form and replacing form with its result.

All built in data structures are supported.

Lazy sequences will be completely consumed (and thus may not be infinite).

fn (prewalk-demo form)

Print each element as it is walked as by :lpy:fn`postwalk`.

fn (prewalk-replace replacements form)

Recursively walk through form as by prewalk, replacing elements appearing as keys in the map replacements with the corresponding values.

fn (stringify-keys form)

Recursively walk form, transforming keyword keys into strings in any maps.

fn (walk inner outer form)

Walk an arbitrary, possibly nested data structure, applying inner to each element of form and then applying outer to the resulting form.

All built in data structures are supported.

Lazy sequences will be completely consumed (and thus may not be infinite).
