<<-
(<<- s)(<<- r s)Unindent multiline text. Uses either a supplied regex or the shortest beginning-of-line to non-whitespace distance
-collapse-whitespace
(collapse-whitespace s)Converts all adjacent whitespace characters to a single space.
-concat
macro
(concat & params)A macro variant of the clojure.core/str function that performs considerbaly faster string concatenation operation on CLJS (on JVM/CLJ it only applies basic simplification and then relies on the clojure.core/str).

-ffmt
macro
(ffmt s & params)Alternative (to istr) string formating macro, that performs simple string formating on the compile time (this means that the string should be known at compile time). Internally it uses the fast string concatenation mechanism implemented in the concat macro.

deprecated
(empty-or-nil? s)Convenient helper for check emptines or if value is nil
+DEPRECATED: this is already covered by empty?
ffmt
macro
(ffmt s & params)Alternative (to istr) string formating macro, that performs simple string formating on the compile time (this means that the string should be known at compile time). Internally it uses the fast string concatenation mechanism implemented in the concat macro.
If you don’t need the peculiarities of the istr macro, this macro should be prefered.
It works with two basic forms: sequencial and indexed. Let seen an example:
(str/ffmt “url(%)” my-url) ; sequential (str/ffmt “url(%1)” my-url) ; indexed
-human
(human s)Output will be: lower cased and space separated accepts strings and keywords
-istr
macro
(istr & strings)A string formating macro that works LIKE ES6 template literals but using clojure construcs and symbols for interpolation delimiters.

+istr
macro
(istr & strings)A string formating macro that works LIKE ES6 template literals but using clojure construcs and symbols for interpolation delimiters.
+It accepts one or more strings; emits a concat invocation that concatenates the string data and evaluated expressions contained within that argument.
Evaluation is controlled using ~{} and ~() forms. The former is used for simple value replacement using clojure.core/str; the latter can be used to embed the results of arbitrary function invocation into the produced string.
+Examples:
+user=> (def v 30.5) user=> (istr “This trial required ~{v}ml of solution.”) “This trial required 30.5ml of solution.” user=> (istr “There are ~(int v) days in November.”) “There are 30 days in November.”
+user=> (def m {:a 1 2 3}) user=> (istr “The total for your order is $~(->> m :a (apply +)).”) “The total for your order is $6.”
+user=> (istr "Just split a long interpolated string up into ~(-> m :a (get 0)), " "~(-> m :a (get 1)), or even ~(-> m :a (get 2)) separate strings " "if you don’t want a << expression to end up being e.g. ~(* 4 (int v)) " “columns wide.”) “Just split a long interpolated string up into 1, 2, or even 3 separate strings if you don’t want a << expression to end up being e.g. 120 columns wide.”
+Note that quotes surrounding string literals within ~() forms must be escaped.
