apply-multi-value clj/s

(apply-multi-value json paths values)

(apply-multi-value json paths values opts-map)

Given json, a JSONPath string paths, and a collection of JSON data value, apply value to the location given by paths in the order they are given. If the location exists, update the pre-existing value. Otherwise, create the necessary data structures needed to contain value.

For example, an array specified by [0,1] in the path, then the first and second elements of value will be applied. Returns the modified json once value or the available path seqs runs out.

The same caveats as apply-value apply here as well:

• If only the root "$" is provided, json is overwritten in its entirety.
• If an array index skips over any vector entries, those skipped entries will be assigned nil.
• If a path contains a wildcard and the location up to that point does not exist or is a scalar, create a new vector.
• If a path contains a wildcard, the location is a collection, and wildcard-append? is true, append it to the coll. In the case of maps, the key is its current size, e.g. {"2" : "foo"}.
• Recursive descent, array slicing, and negative array indices are disallowed (as per strict mode).

The following opts-map fields are supported:

• :first? Apply only the first "|"-separated path.
• :strict? Always set to true regardless of value provided.
• :wildcard-append? Dictates if wildcard values should be appended to the end of existing seqs instead of overwriting existing values. Default false.
• :wildcard-limit Dictates how many wildcard paths should be generated. In overwrite mode, defaults to the length of each coll. In append mode, defaults to 1.

apply-multi-value* clj/s

(apply-multi-value* json paths value opts-map)

Like apply-multi-value except that the paths argument is a vector of already-parsed JSONPaths.

The following opts-map fields are supported:

• :wildcard-append? Dictates if wildcard values should be appended to the end of existing seqs instead of overwriting existing values. Default false.
• :wildcard-limit Dictates the max number of values to applied per coll. In overwrite mode, defaults to the length of each coll. In append mode, defaults to 1.

get-paths clj/s

(get-paths json paths)

Given json and a JSONPath string paths, return a vector of definite key paths. Each key path is a vector of strings (keys) or integers (array indices); non-deterministic path entries like recursive descent and wildcards are removed. If the string contains multiple JSONPaths, we return the key paths for all strings.

The following opts-map fields are supported:

• :first? Only apply the first "|"-separated path.

• '* Wildcard operator
• [...] A vector of strings (keys), integers (array indices), or maps (array slicing operations).

The following opts-map fields are supported:

• :first? Return a singleton vector containing the first path when multiple paths are joined using "|". Default false.

speculate-paths clj/s

(speculate-paths json paths)

(speculate-paths json paths opts-map)

Given json and a JSONPath string paths, return a vector of definite key paths, just like get-paths. However, unlike get-paths, paths will be enumerated even if the corresponding value does not exist in json on that path; in other words, it speculates what paths would exist if they are applied. If the string contains multiple JSONPaths, we return the key paths for all strings.

The following opts-map fields are supported:

• :first? Only apply the first "|"-separated path.
• :strict? Always set to true regardless of value provided.
