-make-format clj

(-make-format lens)

Given a sequence of column widths, return a string suitable for use in format to print a sequences of strings in those columns.

-parse-option clj

(-parse-option {:keys [in update-fn arg-number schema] :as value-schema}
               options
               arg
               argstail)

Take the current arglist head arg, the tail args-tail. Depending on the value schema consume some items from the tail and when applicable pass them on toupdate-fn`. This is actually the core of the work that transforms a vector of string to a map of options.

break-long-option-and-value clj

(break-long-option-and-value arg argstail)

Expand an argument that contains both an option label and a value into two arguments: the label, and the value.

break-short-option-group clj

(break-short-option-group label+value-schemas arg argstail)

Expand a group of short option labels into a several short labels and interpolate them with the tail of the arglist args-tail` depending on the number of arguments each option needs.

children-successor clj

(children-successor schema)

Given a schema [:enum :a :b :c :d], return a Clojure map that return the next item of :a -> :b -> :c -> :d <-> :d. The last item is mapped onto itself. If the schema has a default value as a property, like in [:enum {:default :b} :a :b :c :d] an additional mapping will be made nil -> :c.

Primarily intended to be used on enum schema, but code is generic so you might think of a use case on another schema type.

cli-args-transformer clj

The malli transformer wrapping parse-args. To be used it with m/decode, wrapped by mt/transformer. Merely turn a sequence of arguments args into a map that (maybe) conforms to a schema. You can compose this transformer to further refine command-line argument parsing. See simple-cli-options-transformer for an example.

default-arg-number clj

label+value-schema clj

(label+value-schema {:keys [in schema] :as value-schema})

Return MapEntry items, when applicable one for short, and long option names.

long-option->value-schema clj

(long-option->value-schema default-label value-schema)

name-items clj

(name-items x)

Take an argument and return a vector of items that will form an option name. For example the option name for :a/b will be a-b.

parse-args clj

(parse-args schema args)

Entry point to the technical work of turning a sequece of arguments args into a map that (maybe) conforms to a schema. It returns a map of the options as parsed according to the schema, but with two additional keys:

• ::arguments is a vector of application arguments, that is to say command-line arguments that do not represent an option value.

• ::cli-args is the raw, untouched vector of command-line arguments received as input. Perhaps you need it for some additional validation of positional logic.

ParsingResult clj

prefix-shadowing clj

(prefix-shadowing value-schemas)

remove-key clj

(remove-key f m)

short-option->value-schema clj

(short-option->value-schema default-label value-schema)

simple-cli-options-transformer clj

Simple transformer for the most common use cases when you only want to get a (nested) map of options out of command-line arguments. The mt/default-value-transformer will fill the blank and mt/strip-extra-keys-transformer will remove any extraneous keys. Use it for dumb, do-what-I-mean cli args parsing.

simple-summary clj

(simple-summary schema)

start-with? clj

(start-with? prefix path)

value-schemas clj

(value-schemas schema)

Returns all leaf sub schemas for unique paths as a vector of maps with :schema, :path and :in keys.
