cljs.tools.reader — pfeodrippe/recife 0.4.0

A clojure reader in clojure

*alias-map* cljs

Map from ns alias to ns, if non-nil, it will be used to resolve read-time ns aliases.

Defaults to nil

*data-readers* cljs

Map from reader tag symbols to data reader Vars. Reader tags without namespace qualifiers are reserved for Clojure. This light version of tools.reader has no implementation for default reader tags such as #inst and #uuid.

*default-data-reader-fn* cljs

When no data reader is found for a tag and default-data-reader-fn is non-nil, it will be called with two arguments, the tag and the value. If default-data-reader-fn is nil (the default value), an exception will be thrown for the unknown tag.

*read-delim* cljs

*suppress-read* cljs

bool? cljs

(bool? x)

default-data-readers cljs

Default map of data reader functions provided by Clojure. May be overridden by binding data-readers

map-func cljs

(map-func coll)

Decide which map type to use, array-map if less than 16 elements

read cljs

(read reader)

(read {eof :eof :as opts :or {eof :eofthrow}} reader)

(read reader eof-error? sentinel)

Reads the first object from an IPushbackReader. Returns the object read. If EOF, throws if eof-error? is true. Otherwise returns sentinel. If no stream is provided, in will be used.

Opts is a persistent map with valid keys: :read-cond - :allow to process reader conditionals, or :preserve to keep all branches :features - persistent set of feature keywords for reader conditionals :eof - on eof, return value unless :eofthrow, then throw. if not specified, will throw

To read data structures only, use cljs.tools.reader.edn/read

Note that the function signature of cljs.tools.reader/read and cljs.tools.reader.edn/read is not the same for eof-handling

read+string cljs

(read+string stream)

(read+string opts stream)

(read+string stream eof-error? eof-value)

Like read, and taking the same args. reader must be a SourceLoggingPushbackReader. Returns a vector containing the object read and the (whitespace-trimmed) string read.

read-regex cljs

(read-regex rdr ch opts pending-forms)

read-string cljs

(read-string s)

(read-string opts s)

Reads one object from the string s. Returns nil when s is nil or empty.

To read data structures only, use cljs.tools.reader.edn/read-string

Note that the function signature of cljs.tools.reader/read-string and cljs.tools.reader.edn/read-string is not the same for eof-handling

resolve-symbol cljs

(resolve-symbol s)

Resolve a symbol s into its fully qualified namespace version
