DSL for processing data

combine-proc-fns clj

(combine-proc-fns dsl-expression start-idx end-idx)

Based on the DSL expression dsl-expression, create a data processing function in which the processing rules starting at start-idx, inclusive, up to end-idx, non inclusive, are combined. Please note that it is usually more appropriate to use combine-proc-fns-vec.

combine-proc-fns-vec clj

(combine-proc-fns-vec fn-mapping dsl-expression)

Based on the function mapping fn-mapping and the DSL expression dsl-expression, create a vector of data processing functions. The mapping definition defines the number of processing rules to be included in each processing function. For a vector of processing rules [a b c d e f], a mapping definition [1 2 3] will result in the following association of processing rules to processing functions f_x: [f_1(a), f_2(b, c), f_3(d e f)].

create-proc-fn clj

(create-proc-fn dsl-expression)

Create a data processing function based on the given dsl-expression. An example of a dsl-expression for processing a Clojure seq is given below:

{:output-type :clj-map :rules [['myFloat '(nth 0)] ['myStr '(clojure.string/lower-case (nth 1)) :string] ['myRatio '(/ (nth 2) 100.0)] ['myStr2 '(str (nth 3) (nth 4)) :string]]}

The resulting function will for the input [1.23 "FOO" 42 "bar" "baz"] produce the output {"myFloat" 1.23, "myStr" "foo", "myRatio" 0.42, "myStr2" "barbaz"}.

offset-suffix clj

prefix-rule-name clj

(prefix-rule-name rule-name nesting-level)

Prefix the rule name based on its nesting level to assure that at identifiers at each branch level are unique.
