cider.inlined-deps.puget.v1v0v2.puget.printer — cider/cider-nrepl 0.19.0-SNAPSHOT

Enhanced printing functions for rendering Clojure values. The following options are available to control the printer:

General Rendering

:width

Number of characters to try to wrap pretty-printed forms at.

:print-meta

If true, metadata will be printed before values. Defaults to the value of *print-meta* if unset.

Collection Options

:sort-keys

Print maps and sets with ordered keys. Defaults to true, which will sort all collections. If a number, counted collections will be sorted up to the set size. Otherwise, collections are not sorted before printing.

:map-delimiter

The text placed between key-value pairs in a map.

:map-coll-separator

The text placed between a map key and a collection value. The keyword :line will cause line breaks if the whole map does not fit on a single line.

:seq-limit

If set to a positive number, then lists will only render at most the first n elements. This can help prevent unintentional realization of infinite lazy sequences.

Color Options

:print-color

When true, ouptut colored text from print functions.

:color-markup

:ansi for ANSI color text (the default), :html-inline for inline-styled html, :html-classes to use the names of the keys in the :color-scheme map as class names for spans so styling can be specified via CSS.

:color-scheme

Map of syntax element keywords to color codes.

Type Handling

:print-handlers

A lookup function which will return a rendering function for a given class type. This will be tried before the built-in type logic. See the cider.inlined-deps.puget.v1v0v2.puget.dispatch namespace for some helpful constructors. The returned function should accept the current printer and the value to be rendered, returning a format document.

:print-fallback

Keyword argument specifying how to format unknown values. Puget supports a few different options:

• :pretty renders values with the default colored representation.
• :print defers to the standard print method by rendering unknown values using pr-str.
• :error will throw an exception when types with no defined handler are encountered.
• A function value will be called with the current printer options and the unknown value and is expected to return a formatting document representing it.

*options* clj

Default options to use when constructing new printers.

canonical-printer clj

(canonical-printer)

(canonical-printer handlers)

Constructs a new canonical printer with the given handler dispatch.

clojure-handlers clj

Map of print handlers for 'primary' Clojure types. These should take precedence over the handlers in clojure-interface-handlers.

clojure-interface-handlers clj

Fallback print handlers for other Clojure interfaces.

color-text clj

(color-text element text)

(color-text options element text)

Produces text colored according to the active color scheme. This is mostly useful to clients which want to produce output which matches data printed by Puget, but which is not directly printed by the library. Note that this function still obeys the :print-color option.

common-handlers clj

Print handler dispatch combining Java and Clojure handlers with inheritance lookups. Provides a similar experience as the standard Clojure pretty-printer.

cprint clj

(cprint value)

(cprint value opts)

Like pprint, but turns on colored output.

cprint-str clj

(cprint-str value)

(cprint-str value opts)

Pretty-prints a value to a colored string.

format-doc clj

(format-doc printer value)

Recursively renders a print document for the given value.

format-doc* clj

(format-doc* printer value)

Formats a document without considering metadata.

format-unknown clj

(format-unknown printer value)

(format-unknown printer value repr)

(format-unknown printer value tag repr)

Renders common syntax doc for an unknown representation of a value.

java-handlers clj

Map of print handlers for Java types. This supports syntax for regular expressions, dates, UUIDs, and futures.

merge-options clj

(merge-options a b)

Merges maps of printer options, taking care to combine the color scheme correctly.

pprint clj

(pprint value)

(pprint value opts)

Pretty-prints a value to out. Options may be passed to override the default options map.

pprint-str clj

(pprint-str value)

(pprint-str value opts)

Pretty-print a value to a string.

pr-handler clj

(pr-handler printer value)

Print handler which renders the value with pr-str.

pretty-printer clj

(pretty-printer opts)

Constructs a new printer from the given configuration.

render-out clj

(render-out printer value)

Prints a value using the given printer.

render-str clj

(render-str printer value)

Renders a value to a string using the given printer.

tagged-handler clj

(tagged-handler tag value-fn)

Generates a print handler function which renders a tagged-literal with the given tag and a value produced by calling the function.

unknown-handler clj

(unknown-handler printer value)

Print handler which renders the value using the printer's unknown type logic.

with-color clj macro

(with-color & body)

Executes the given expressions with colored output enabled.

with-options clj macro

(with-options opts & body)

Executes the given expressions with a set of options merged into the current option map.
