aggregate-time-stats-str clj

all-columns-not-nil? clj

(all-columns-not-nil? rm column-keywords-seq)

Given an rm, ensures that all column-keywords specfied do not have nulls/nils in them.

convert-string-to-inputstream clj

(convert-string-to-inputstream in-str)

From http://stackoverflow.com/questions/247161/how-do-i-turn-a-string-into-a-stream-in-java, http://stackoverflow.com/questions/7498067/why-does-bytearrayinputstream-doesnt-return-expected-results Is a java.io.InputStream

copy-map-with-values clj

(copy-map-with-values m new-val-fn)

Recursively reates a copy of a map replacing the values with (new-val-fn v). Adapted from clojure.walk/keywordize-keys.

count-stats-str clj

create-app-exception clj

(create-app-exception exception-name error-msg additional-info-map)

Is just a convenience constructor around ex-info for consistency

ds-processing-time-str clj

enable-enter-method-tracing clj

(enable-enter-method-tracing)

To add tracing to all app namespaces. Calling .toString on ns gives the name of namespace, https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Namespace.java

enter-function-str clj

floats-equal clj

(floats-equal float-1 float-2)

Need to parse/cast just to be sure comparing apples to apples.

possibly alternative implementation if needed: http://gettingclojure.wikidot.com/cookbook:numbers

get-local-date-ms-timestamp clj

(get-local-date-ms-timestamp local-date)

Given a local date, returns the unix timestamp value for it for the beginning of the day in UTC. Timestamp is in milliseconds.

get-npprint-map clj

(get-npprint-map in-map vals-fn)

A logging function for passing the vals of a map through a function.

vals-fn takes in 1 arg, the value of the kvp-pair of the map

get-stacktrace-str clj

(get-stacktrace-str e)

For printing out a stacktrace to a string. Output basically equivalent to (-> e (.printStackTrace)), except in REPL output is truncatd unless clicked on, in plain text no difference, so good enough. Can't use (-> e (.printStackTrace)) because it prints to err string, which capturing via http://stackoverflow.com/questions/17314128/get-stacktrace-as-string doesn't work. Alternatively, can use a full java way with either apache commons library or create and close a StringWriter and PrintWriter, http://stackoverflow.com/questions/1149703/how-can-i-convert-a-stack-trace-to-a-string

get-utc-now-zoned-dt clj

(get-utc-now-zoned-dt)

get-zoned-date-time-ms-timestamp clj

(get-zoned-date-time-ms-timestamp zoned-date-time)

Returns unix timestamp, to get Instant from unix timestamp in milliseconds, use Instant/ofEpochMilli

http-time-str clj

json-response-ok? clj

(json-response-ok? ring-response-map)

For standard http get returning json using clj-http's (get)

local-date-in-range? clj

(local-date-in-range? start-local-date end-local-date local-date)

parse-float clj

(parse-float in-str)

Returns nil if in-str is nil, also works for numbers.

parse-int clj

(parse-int in-str)

Returns nil if in-str is nil, also works for numbers.

parse-iso-8601-str-to-zdt clj

(parse-iso-8601-str-to-zdt iso-dt-str)

Need to add UTC timezone for it to be equality compatible other zoned dts that have the zone id set.

parse-long clj

(parse-long in-str)

Returns nil if in-str is nil, also works for numbers.

parse-short clj

(parse-short in-str)

Returns nil if in-str is nil, also works for numbers.

round-to-num-decimal-places clj

(round-to-num-decimal-places n num-decimal-places)

(round-to-num-decimal-places n num-decimal-places rounding-mode)

Convenience method for rounding numbers, dynamically creates (DecimalFormat.) so can make that instantiate at run-time if need more speed.

Probably supeceded by apache commons math (Precision/round) now, with -ve decimal places mean 10, 100, etc. https://stackoverflow.com/questions/5775866/how-to-round-integer-in-java

section-start-str clj

section-time-str clj

trace-ns clj

(trace-ns ns)

For adding a logging statement to the beginning to each function call, for a given namespace, most clj functions that are useful here are on a per-name space basis, so use that Replaces each function from the given namespace with a version wrapped in a tracing call. Can be undone with untrace-ns. ns should be a namespace object or a symbol.

From http://stackoverflow.com/questions/3346382/clojure-adding-a-debug-trace-to-every-function-in-a-namespace, https://gist.github.com/michalmarczyk/492764 Is now actually part of clojure.tools.trace, but I have version here both for own logging and for betting commenting.

Unfortunately, doesn't work with prismatic schema defn functions, so useless for now.

untrace-ns clj

(untrace-ns ns)

Reverses the effect of trace-ns, replacing each traced function from the given namespace with the original, untraced version.
