nnichols.parse — nnichols 1.1.0

A bunch of utility functions for parsing strings to the types they represent

float-regex clj/s

float-string? clj/s

(float-string? float-string)

Returns true if float-string representss a valid float, false otherwise.

parse-binary clj/s

(parse-binary binary-str)

Parse binary-str to the positive integer it represents in binary

parse-binary-or-zero clj/s

(parse-binary-or-zero binary-str)

Like try-parse-binary, but returns a 0 instead of nil. Useful when passing return values into numeric operations.

parse-boolean clj/s

(parse-boolean bool-str)

Like parse-boolean-string, but returns boolean values passed through and uses clojure's definition of truthiness for all other values

parse-boolean-strict clj/s

(parse-boolean-strict bool-str)

Like parse-boolean, but throws an exception for values that are neither booleans nor true/false strings. Useful for spec/conformance.

parse-boolean-string clj/s

(parse-boolean-string bool-str)

Convert bool-str to a boolean for the strings true/false (Any casing)

parse-double clj

(parse-double double-string)

Parse double-string to an instance of the JVM's Double class

parse-double-or-zero clj

(parse-double-or-zero double-string)

Like try-parse-double, but returns 0.0 instead of nil. Useful when passing return values into numeric operations.

parse-float clj/s

(parse-float float-string)

Parse float-string to the floating point decimal it represents

parse-float-or-zero clj/s

(parse-float-or-zero float-string)

Like try-parse-float, but returns 0.0 instead of nil. Useful when passing return values into numeric operations.

parse-guid clj/s

(parse-guid guid-str)

Parse guid-str to the GUID it represents

parse-hex clj/s

(parse-hex hex-str)

Parse hex-str to the positive integer it represents in hexidecimal

parse-hex-or-zero clj/s

(parse-hex-or-zero hex-str)

Like try-parse-hex, but returns a 0 instead of nil. Useful when passing return values into numeric operations.

parse-int clj/s

(parse-int dec-str)

Parses dec-str to the positive integer it represents

parse-int-or-zero clj/s

(parse-int-or-zero int-str)

Like try-parse-int, but returns a 0 instead of nil. Useful when passing return values into numeric operations.

parse-octal clj/s

(parse-octal octal-str)

Parse octal-str to the positive integer it represents in octal

parse-octal-or-zero clj/s

(parse-octal-or-zero octal-str)

Like try-parse-octal, but returns a 0 instead of nil. Useful when passing return values into numeric operations.

parse-radix clj/s

(parse-radix int-str radix)

Convert int-str to the positive integer it represents w.r.t. the radix e.g. (parse-radix "10010" 2) would return 18

parse-radix-or-zero clj/s

(parse-radix-or-zero int-str radix)

Like try-parse-radix, but returns a 0 instead of nil. Useful when passing return values into numeric operations.

parse-uuid clj/s

(parse-uuid uuid-str)

Parse uuid-str to the UUID it represents

try-parse-binary clj/s

Like parse-binary, but returns nil for invalid input.

try-parse-boolean-string clj/s

Like parse-binary, but returns nil for invalid input.

try-parse-double clj

(try-parse-double double-string)

Like parse-double, but returns double-string for doubles, and nil for invalid input

try-parse-float clj/s

(try-parse-float float-string)

Like parse-float, but returns float-string for floats, and nil for invalid input

try-parse-guid clj/s

(try-parse-guid u)

Like parse-guid, but returns u if it's already a GUID, or nil for invalid inputs.

try-parse-hex clj/s

Like parse-hex, but returns nil for invalid input.

try-parse-int clj/s

Like parse-int, but returns nil for invalid input.

try-parse-octal clj/s

Like parse-octal, but returns nil for invalid input.

try-parse-radix clj/s

Like parse-radix, but returns nil for invalid input.

try-parse-uuid clj/s

(try-parse-uuid u)

Like parse-uuid, but returns u if it's already a UUID, or nil for invalid inputs.
