Bloblang Methods
Methods provide most of the power in Bloblang as they allow you to augment values and can be added to any expression (including other methods):
root.doc.id = this.thing.id.string().catch(uuid_v4())
root.doc.reduced_nums = this.thing.nums.map_each(num -> if num < 10 {
deleted()
} else {
num - 10
})
root.has_good_taste = ["pikachu","mewtwo","magmar"].contains(this.user.fav_pokemon)Methods support both named and nameless style arguments:
root.foo_one = this.(bar | baz).trim().replace_all(old: "dog", new: "cat")
root.foo_two = this.(bar | baz).trim().replace_all("dog", "cat")General
apply
Apply a declared mapping to a target value.
Examples
map thing {
root.inner = this.first
}
root.foo = this.doc.apply("thing")
# In: {"doc":{"first":"hello world"}}
# Out: {"foo":{"inner":"hello world"}}map create_foo {
root.name = "a foo"
root.purpose = "to be a foo"
}
root = this
root.foo = null.apply("create_foo")
# In: {"id":"1234"}
# Out: {"foo":{"name":"a foo","purpose":"to be a foo"},"id":"1234"}catch
If the result of a target query fails (due to incorrect types, failed parsing, etc) the argument is returned instead.
Parameters
fallback <query expression> A value to yield, or query to execute, if the target query fails.
Examples
root.doc.id = this.thing.id.string().catch(uuid_v4())The fallback argument can be a mapping, allowing you to capture the error string and yield structured data back.
root.url = this.url.parse_url().catch(err -> {"error":err,"input":this.url})
# In: {"url":"invalid %&# url"}
# Out: {"url":{"error":"field `this.url`: parse \"invalid %&\": invalid URL escape \"%&\"","input":"invalid %&# url"}}When the input document is not structured attempting to reference structured fields with this will result in an error. Therefore, a convenient way to delete non-structured data is with a catch.
root = this.catch(deleted())
# In: {"doc":{"foo":"bar"}}
# Out: {"doc":{"foo":"bar"}}
# In: not structured data
# Out: <Message deleted>exists
Checks that a field, identified via a dot path, exists in an object.
Parameters
path <string> A dot path to a field.
from
Modifies a target query such that certain functions are executed from the perspective of another message in the batch. This allows you to mutate events based on the contents of other messages. Functions that support this behavior are content, json and meta.
from_all
Modifies a target query such that certain functions are executed from the perspective of each message in the batch, and returns the set of results as an array. Functions that support this behavior are content, json and meta.
String Manipulation
capitalize
Takes a string value and returns a copy with all Unicode letters that begin words mapped to their Unicode title case.
compare_argon2
Checks whether a string matches a hashed secret using Argon2.
Parameters
hashed_secret <string> The hashed secret to compare with the input. This must be a fully-qualified string which encodes the Argon2 options used to generate the hash.
Examples
root.match = this.secret.compare_argon2("$argon2id$v=19$m=4096,t=3,p=1$c2FsdHktbWNzYWx0ZmFjZQ$RMUMwgtS32/mbszd+ke4o4Ej1jFpYiUqY6MHWa69X7Y")
# In: {"secret":"there-are-many-blobs-in-the-sea"}
# Out: {"match":true}root.match = this.secret.compare_argon2("$argon2id$v=19$m=4096,t=3,p=1$c2FsdHktbWNzYWx0ZmFjZQ$RMUMwgtS32/mbszd+ke4o4Ej1jFpYiUqY6MHWa69X7Y")
# In: {"secret":"will-i-ever-find-love"}
# Out: {"match":false}compare_bcrypt
Checks whether a string matches a hashed secret using bcrypt.
Examples
root.match = this.secret.compare_bcrypt("$2y$10$Dtnt5NNzVtMCOZONT705tOcS8It6krJX8bEjnDJnwxiFKsz1C.3Ay")
# In: {"secret":"there-are-many-blobs-in-the-sea"}
# Out: {"match":true}root.match = this.secret.compare_bcrypt("$2y$10$Dtnt5NNzVtMCOZONT705tOcS8It6krJX8bEjnDJnwxiFKsz1C.3Ay")
# In: {"secret":"will-i-ever-find-love"}
# Out: {"match":false}escape_html
Escapes a string so that special characters like < to become <. It escapes only five such characters: <, >, &, ' and " so that it can be safely placed within an HTML entity.
filepath_join
Joins an array of path elements into a single file path. The separator depends on the operating system of the machine.
filepath_split
Splits a file path immediately following the final Separator, separating it into a directory and file name component returned as a two element array of strings. If there is no Separator in the path, the first element will be empty and the second will contain the path. The separator depends on the operating system of the machine.
format
Use a value string as a format specifier in order to produce a new string, using any number of provided arguments. Please refer to the Go fmt package documentation for the list of valid format verbs.
index_of
Returns the starting index of the argument substring in a string target, or -1 if the target doesn’t contain the argument.
quote
Quotes a target string using escape sequences (\t, \n, \xFF, \u0100) for control characters and non-printable characters.
replace_all
Replaces all occurrences of the first argument in a target string with the second argument.
replace_all_many
For each pair of strings in an argument array, replaces all occurrences of the first item of the pair with the second. This is a more compact way of chaining a series of replace_all methods.
slice
Extract a slice from a string by specifying two indices, a low and high bound, which selects a half-open range that includes the first character, but excludes the last one. If the second index is omitted then it defaults to the length of the input sequence.
Parameters
low <integer> The low bound, which is the first element of the selection, or if negative selects from the end.
high <(optional) integer> An optional high bound.
Examples
root.beginning = this.value.slice(0, 2)
root.end = this.value.slice(4)
# In: {"value":"foo bar"}
# Out: {"beginning":"fo","end":"bar"}A negative low index can be used, indicating an offset from the end of the sequence. If the low index is greater than the length of the sequence then an empty result is returned.
root.last_chunk = this.value.slice(-4)
root.the_rest = this.value.slice(0, -4)
# In: {"value":"foo bar"}
# Out: {"last_chunk":" bar","the_rest":"foo"}slug
|

Timestamp Manipulation
parse_duration
Attempts to parse a string as a duration and returns an integer of nanoseconds. A duration string is a possibly signed sequence of decimal numbers, each with an optional fraction and a unit suffix, such as "300ms", "-1.5h" or "2h45m". Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
parse_duration_iso8601
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Attempts to parse a string using ISO-8601 rules as a duration and returns an integer of nanoseconds. A duration string is represented by the format "P[n]Y[n]M[n]DT[n]H[n]M[n]S" or "P[n]W". In these representations, the "[n]" is replaced by the value for each of the date and time elements that follow the "[n]". For example, "P3Y6M4DT12H30M5S" represents a duration of "three years, six months, four days, twelve hours, thirty minutes, and five seconds". The last field of the format allows fractions with one decimal place, so "P3.5S" will return 3500000000ns. Any additional decimals will be truncated.
Examples
Arbitrary ISO-8601 duration string to nanoseconds:
root.delay_for_ns = this.delay_for.parse_duration_iso8601()
# In: {"delay_for":"P3Y6M4DT12H30M5S"}
# Out: {"delay_for_ns":110839937000000000}Two hours ISO-8601 duration string to seconds:
root.delay_for_s = this.delay_for.parse_duration_iso8601() / 1000000000
# In: {"delay_for":"PT2H"}
# Out: {"delay_for_s":7200}Two and a half seconds ISO-8601 duration string to seconds:
root.delay_for_s = this.delay_for.parse_duration_iso8601() / 1000000000
# In: {"delay_for":"PT2.5S"}
# Out: {"delay_for_s":2.5}ts_add_iso8601
|

Attempts to format a timestamp value as a string according to a specified format, or RFC 3339 by default. Timestamp values can either be a numerical unix time in seconds (with up to nanosecond precision via decimals), or a string in RFC 3339 format.
The output format is defined by showing how the reference time, defined to be Mon Jan 2 15:04:05 -0700 MST 2006, would be displayed if it were the value. For an alternative way to specify formats check out the ts_strftime method.
Parameters
format <string, default "2006-01-02T15:04:05.999999999Z07:00"> The output format to use.
tz <(optional) string> An optional timezone to use, otherwise the timezone of the input string is used, or in the case of unix timestamps the local timezone is used.
Examples
root.something_at = (this.created_at + 300).ts_format()An optional string argument can be used in order to specify the output format of the timestamp. The format is defined by showing how the reference time, defined to be Mon Jan 2 15:04:05 -0700 MST 2006, would be displayed if it were the value.
root.something_at = (this.created_at + 300).ts_format("2006-Jan-02 15:04:05")A second optional string argument can also be used in order to specify a timezone, otherwise the timezone of the input string is used, or in the case of unix timestamps the local timezone is used.
root.something_at = this.created_at.ts_format(format: "2006-Jan-02 15:04:05", tz: "UTC")
# In: {"created_at":1597405526}
# Out: {"something_at":"2020-Aug-14 11:45:26"}
# In: {"created_at":"2020-08-14T11:50:26.371Z"}
# Out: {"something_at":"2020-Aug-14 11:50:26"}And ts_format supports up to nanosecond precision with floating point timestamp values.
root.something_at = this.created_at.ts_format("2006-Jan-02 15:04:05.999999", "UTC")
# In: {"created_at":1597405526.123456}

# In: {"created_at":"2020-08-14T11:50:26.371Z"}
# Out: {"something_at":"2020-Aug-14 11:50:26.371"}ts_parse
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Attempts to parse a string as a timestamp following a specified format and outputs a timestamp, which can then be fed into methods such as ts_format.
The input format is defined by showing how the reference time, defined to be Mon Jan 2 15:04:05 -0700 MST 2006, would be displayed if it were the value. For an alternative way to specify formats check out the ts_strptime method.
ts_round
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Returns the result of rounding a timestamp to the nearest multiple of the argument duration (nanoseconds). The rounding behavior for halfway values is to round up. Timestamp values can either be a numerical unix time in seconds (with up to nanosecond precision via decimals), or a string in RFC 3339 format. The ts_parse method can be used in order to parse different timestamp formats.
ts_strftime
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |

Parameters
format <string> The output format to use.
tz <(optional) string> An optional timezone to use, otherwise the timezone of the input string is used.
Examples
The format consists of zero or more conversion specifiers and ordinary characters (except %). All ordinary characters are copied to the output string without modification. Each conversion specification begins with % character followed by the character that determines the behavior of the specifier. Please refer to man 3 strftime for the list of format specifiers.
root.something_at = (this.created_at + 300).ts_strftime("%Y-%b-%d %H:%M:%S")A second optional string argument can also be used in order to specify a timezone, otherwise the timezone of the input string is used, or in the case of unix timestamps the local timezone is used.

A floating-point number that represents a Unix timestamp (in seconds)
-
A string in the RFC 3339 format
You can also provide an optional argument, which is returned when the value cannot be parsed into a timestamp. The output of this method can be further transformed using timestamp manipulation methods.
type
Returns the type of a value as a string, providing one of the following values: string, bytes, number, bool, timestamp, array, object or null.
Examples
root.bar_type = this.bar.type()
root.foo_type = this.foo.type()
# In: {"bar":10,"foo":"is a string"}
# Out: {"bar_type":"number","foo_type":"string"}root.type = this.type()
# In: "foobar"
# Out: {"type":"string"}
# In: 666
# Out: {"type":"number"}
# In: false
# Out: {"type":"bool"}
# In: ["foo", "bar"]
# Out: {"type":"array"}
# In: {"foo": "bar"}
# Out: {"type":"object"}
# In: null
# Out: {"type":"null"}root.type = content().type()
# In: foobar
# Out: {"type":"bytes"}root.type = this.ts_parse("2006-01-02").type()
# In: "2022-06-06"
# Out: {"type":"timestamp"}Object & Array Manipulation
all
Checks each element of an array against a query and returns true if all elements passed. An error occurs if the target is not an array, or if any element results in the provided query returning a non-boolean result. Returns false if the target array is empty.
any
Checks the elements of an array against a query and returns true if any element passes. An error occurs if the target is not an array, or if an element results in the provided query returning a non-boolean result. Returns false if the target array is empty.
assign
Merge a source object into an existing destination object. When a collision is found within the merged structures (both a source and destination object contain the same non-object keys) the value in the destination object will be overwritten by that of source object. In order to preserve both values on collision use the merge method.
collapse
Collapse an array or object into an object of key/value pairs for each field, where the key is the full path of the structured field in dot path notation. Empty arrays an objects are ignored by default.
Parameters
include_empty <bool, default false> Whether to include empty objects and arrays in the resulting object.
Examples
root.result = this.collapse()
# In: {"foo":[{"bar":"1"},{"bar":{}},{"bar":"2"},{"bar":[]}]}
# Out: {"result":{"foo.0.bar":"1","foo.2.bar":"2"}}An optional boolean parameter can be set to true in order to include empty objects and arrays.
root.result = this.collapse(include_empty: true)
# In: {"foo":[{"bar":"1"},{"bar":{}},{"bar":"2"},{"bar":[]}]}
# Out: {"result":{"foo.0.bar":"1","foo.1.bar":{},"foo.2.bar":"2","foo.3.bar":[]}}contains
Checks whether an array contains an element matching the argument, or an object contains a value matching the argument, and returns a boolean result. Numerical comparisons are made irrespective of the representation type (float versus integer).
Examples
root.has_foo = this.thing.contains("foo")
# In: {"thing":["this","foo","that"]}
# Out: {"has_foo":true}
# In: {"thing":["this","bar","that"]}
# Out: {"has_foo":false}root.has_bar = this.thing.contains(20)
# In: {"thing":[10.3,20.0,"huh",3]}
# Out: {"has_bar":true}
# In: {"thing":[2,3,40,67]}
# Out: {"has_bar":false}diff

This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Create a diff by comparing the current value with the given one. Wraps the github.com/r3labs/diff/v3 package. See its docs for more information.
enumerated
Converts an array into a new array of objects, where each object has a field index containing the index of the element and a field value containing the original value of the element.
explode
Explodes an array or object at a field path.
Parameters
path <string> A dot path to a field to explode.
Examples
On arrays
Exploding arrays results in an array containing elements matching the original document, where the target field of each element is an element of the exploded array:
root = this.explode("value")
# In: {"id":1,"value":["foo","bar","baz"]}
# Out: [{"id":1,"value":"foo"},{"id":1,"value":"bar"},{"id":1,"value":"baz"}]On objects
Exploding objects results in an object where the keys match the target object, and the values match the original document but with the target field replaced by the exploded value:
root = this.explode("value")
# In: {"id":1,"value":{"foo":2,"bar":[3,4],"baz":{"bev":5}}}
# Out: {"bar":{"id":1,"value":[3,4]},"baz":{"id":1,"value":{"bev":5}},"foo":{"id":1,"value":2}}filter
Executes a mapping query argument for each element of an array or key/value pair of an object. If the query returns false the item is removed from the resulting array or object. The item will also be removed if the query returns any non-boolean value.
Parameters
test <query expression> A query to apply to each element, if this query resolves to any value other than a boolean true the element will be removed from the result.
Examples
root.new_nums = this.nums.filter(num -> num > 10)
# In: {"nums":[3,11,4,17]}
# Out: {"new_nums":[11,17]}On objects
When filtering objects the mapping query argument is provided a context with a field key containing the value key, and a field value containing the value.
root.new_dict = this.dict.filter(item -> item.value.contains("foo"))
# In: {"dict":{"first":"hello foo","second":"world","third":"this foo is great"}}
# Out: {"new_dict":{"first":"hello foo","third":"this foo is great"}}find
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Returns the index of the first occurrence of a value in an array. -1 is returned if there are no matches. Numerical comparisons are made irrespective of the representation type (float versus integer).
find_all
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Returns an array containing the indexes of all occurrences of a value in an array. An empty array is returned if there are no matches. Numerical comparisons are made irrespective of the representation type (float versus integer).
find_all_by
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Returns an array containing the indexes of all occurrences of an array where the provided query resolves to a boolean true. An empty array is returned if there are no matches. Numerical comparisons are made irrespective of the representation type (float versus integer).
find_by
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Returns the index of the first occurrence of an array where the provided query resolves to a boolean true. -1 is returned if there are no matches.
flatten
Iterates an array and any element that is itself an array is removed and has its elements inserted directly in the resulting array.
fold
Takes two arguments: an initial value, and a mapping query. For each element of an array the mapping context is an object with two fields tally and value, where tally contains the current accumulated value and value is the value of the current element. The mapping must return the result of adding the value to the tally.
The first argument is the value that tally will have on the first call.
Parameters
initial <unknown> The initial value to start the fold with. For example, an empty object {}, a zero count 0, or an empty string "".
query <query expression> A query to apply for each element. The query is provided an object with two fields; tally containing the current tally, and value containing the value of the current element. The query should result in a new tally to be passed to the next element query.
Examples
root.sum = this.foo.fold(0, item -> item.tally + item.value)
# In: {"foo":[3,8,11]}
# Out: {"sum":22}root.result = this.foo.fold("", item -> "%v%v".format(item.tally, item.value))
# In: {"foo":["hello ", "world"]}
# Out: {"result":"hello world"}You can use fold to merge an array of objects together:
root.smoothie = this.fruits.fold({}, item -> item.tally.merge(item.value))
# In: {"fruits":[{"apple":5},{"banana":3},{"orange":8}]}
# Out: {"smoothie":{"apple":5,"banana":3,"orange":8}}get
Extract a field value, identified via a dot path, from an object.
Parameters
path <string> A dot path identifying a field to obtain.
index
Extract an element from an array by an index. The index can be negative, and if so the element will be selected from the end counting backwards starting from -1. E.g. an index of -1 returns the last element, an index of -2 returns the element before the last, and so on.
Examples
root.last_name = this.names.index(-1)
# In: {"names":["rachel","stevens"]}
# Out: {"last_name":"stevens"}It is also possible to use this method on byte arrays, in which case the selected element will be returned as an integer.
root.last_byte = this.name.bytes().index(-1)
# In: {"name":"foobar bazson"}
# Out: {"last_byte":110}json_path
|
Experimental
This method is experimental and breaking changes could be made to it outside of major version releases. |
Executes the given JSONPath expression on an object or array and returns the result. The JSONPath expression syntax can be found at https://goessner.net/articles/JsonPath/. For more complex logic, you can use Gval expressions (https://github.com/PaesslerAG/gval).
Examples
root.all_names = this.json_path("$..name")
# In: {"name":"alice","foo":{"name":"bob"}}
# Out: {"all_names":["alice","bob"]}
# In: {"thing":["this","bar",{"name":"alice"}]}
# Out: {"all_names":["alice"]}root.text_objects = this.json_path("$.body[?(@.type=='text')]")
# In: {"body":[{"type":"image","id":"foo"},{"type":"text","id":"bar"}]}
# Out: {"text_objects":[{"id":"bar","type":"text"}]}json_schema
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Checks a JSON schema against a value and returns the value if it matches or throws and error if it does not.
Examples
root = this.json_schema("""{
"type":"object",
"properties":{
"foo":{
"type":"string"
}
}
}""")
# In: {"foo":"bar"}
# Out: {"foo":"bar"}
# In: {"foo":5}
# Out: Error("failed assignment (line 1): field `this`: foo invalid type. expected: string, given: integer")In order to load a schema from a file use the file function.
root = this.json_schema(file(env("BENTHOS_TEST_BLOBLANG_SCHEMA_FILE")))key_values
Returns the key/value pairs of an object as an array, where each element is an object with a key field and a value field. The order of the resulting array will be random.
map_each
Examples
On arrays
Apply a mapping to each element of an array and replace the element with the result. Within the argument mapping the context is the value of the element being mapped.
root.new_nums = this.nums.map_each(num -> if num < 10 {
deleted()
} else {
num - 10
})
# In: {"nums":[3,11,4,17]}
# Out: {"new_nums":[1,7]}On objects
Apply a mapping to each value of an object and replace the value with the result. Within the argument mapping the context is an object with a field key containing the value key, and a field value.
root.new_dict = this.dict.map_each(item -> item.value.uppercase())
# In: {"dict":{"foo":"hello","bar":"world"}}
# Out: {"new_dict":{"bar":"WORLD","foo":"HELLO"}}map_each_key
Apply a mapping to each key of an object, and replace the key with the result, which must be a string.
Examples
root.new_dict = this.dict.map_each_key(key -> key.uppercase())
# In: {"dict":{"keya":"hello","keyb":"world"}}
# Out: {"new_dict":{"KEYA":"hello","KEYB":"world"}}root = this.map_each_key(key -> if key.contains("kafka") { "_" + key })
# In: {"amqp_key":"foo","kafka_key":"bar","kafka_topic":"baz"}
# Out: {"_kafka_key":"bar","_kafka_topic":"baz","amqp_key":"foo"}merge
Merge a source object into an existing destination object. When a collision is found within the merged structures (both a source and destination object contain the same non-object keys) the result will be an array containing both values, where values that are already arrays will be expanded into the resulting array. In order to simply override destination fields on collision use the assign method.

slice
Extract a slice from an array by specifying two indices, a low and high bound, which selects a half-open range that includes the first element, but excludes the last one. If the second index is omitted then it defaults to the length of the input sequence.
Parameters
low <integer> The low bound, which is the first element of the selection, or if negative selects from the end.
high <(optional) integer> An optional high bound.
Examples
root.beginning = this.value.slice(0, 2)
root.end = this.value.slice(4)
# In: {"value":["foo","bar","baz","buz","bev"]}
# Out: {"beginning":["foo","bar"],"end":["bev"]}A negative low index can be used, indicating an offset from the end of the sequence. If the low index is greater than the length of the sequence then an empty result is returned.
root.last_chunk = this.value.slice(-2)
root.the_rest = this.value.slice(0, -2)
# In: {"value":["foo","bar","baz","buz","bev"]}
# Out: {"last_chunk":["buz","bev"],"the_rest":["foo","bar","baz"]}sort
Attempts to sort the values of an array in increasing order. The type of all values must match in order for the ordering to succeed. Supports string and number values.
Parameters
compare <(optional) query expression> An optional query that should explicitly compare elements left and right and provide a boolean result.
Examples
root.sorted = this.foo.sort()
# In: {"foo":["bbb","ccc","aaa"]}
# Out: {"sorted":["aaa","bbb","ccc"]}It’s also possible to specify a mapping argument, which is provided an object context with fields left and right, the mapping must return a boolean indicating whether the left value is less than right. This allows you to sort arrays containing non-string or non-number values.
root.sorted = this.foo.sort(item -> item.left.v < item.right.v)
# In: {"foo":[{"id":"foo","v":"bbb"},{"id":"bar","v":"ccc"},{"id":"baz","v":"aaa"}]}
# Out: {"sorted":[{"id":"baz","v":"aaa"},{"id":"foo","v":"bbb"},{"id":"bar","v":"ccc"}]}sort_by
Attempts to sort the elements of an array, in increasing order, by a value emitted by an argument query applied to each element. The type of all values must match in order for the ordering to succeed. Supports string and number values.
squash
Squashes an array of objects into a single object, where key collisions result in the values being merged (following similar rules as the .merge() method)
Examples
root.locations = this.locations.map_each(loc -> {loc.state: [loc.name]}).squash()
# In: {"locations":[{"name":"Seattle","state":"WA"},{"name":"New York","state":"NY"},{"name":"Bellevue","state":"WA"},{"name":"Olympia","state":"WA"}]}
# Out: {"locations":{"NY":["New York"],"WA":["Seattle","Bellevue","Olympia"]}}unique
Attempts to remove duplicate values from an array. The array may contain a combination of different value types, but numbers and strings are checked separately ("5" is a different element to 5).
values
Returns the values of an object as an array. The order of the resulting array will be random.
with
Returns an object where all but one or more field path arguments are removed. Each path specifies a specific field to be retained from the input object, allowing for nested fields.
If a key within a nested path does not exist then it is ignored.
without
Returns an object where one or more field path arguments are removed. Each path specifies a specific field to be deleted from the input object, allowing for nested fields.
If a key within a nested path does not exist or is not an object then it is not removed.
Parsing
bloblang
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Executes an argument Bloblang mapping on the target. This method can be used in order to execute dynamic mappings. Imports and functions that interact with the environment, such as file and env, or that access message information directly, such as content or json, are not enabled for dynamic Bloblang mappings.
Examples
root.body = this.body.bloblang(this.mapping)
# In: {"body":{"foo":"hello world"},"mapping":"root.foo = this.foo.uppercase()"}
# Out: {"body":{"foo":"HELLO WORLD"}}
# In: {"body":{"foo":"hello world 2"},"mapping":"root.foo = this.foo.capitalize()"}
# Out: {"body":{"foo":"Hello World 2"}}format_json
|
This method is in beta and may be subject to breaking changes if issues or improvements are identified. |
Serializes a target value into a pretty-printed JSON byte array (with 4 space indentation by default).
Parameters

If an element contains attributes they are parsed by prefixing a hyphen,
-, to the attribute label. -
If the element is a simple element and has attributes, the element value is given the key
#text. -
XML comments, directives, and process instructions are ignored.
-
When elements are repeated the resulting JSON value is an array.

Encodes a string or byte array target according to a chosen scheme and returns a string result. Available schemes are: base64, base64url (RFC 4648 with padding characters), base64rawurl (RFC 4648 without padding characters), hex, ascii85.
encrypt_aes
Encrypts a string or byte array target according to a chosen AES encryption method and returns a string result. The algorithms require a key and an initialization vector / nonce. Available schemes are: ctr, gcm, ofb, cbc.
hash
Hashes a string or byte array according to a chosen algorithm and returns the result as a byte array. When mapping the result to a JSON field the value should be cast to a string using the method string, or encoded using the method encode, otherwise it will be base64 encoded by default.
Available algorithms are: hmac_sha1, hmac_sha256, hmac_sha512, md5, sha1, sha256, sha512, xxhash64, crc32, fnv32.
The following algorithms require a key, which is specified as a second argument: hmac_sha1, hmac_sha256, hmac_sha512.
Parameters
algorithm <string> The hasing algorithm to use.
key <(optional) string> An optional key to use.
polynomial <string, default "IEEE"> An optional polynomial key to use when selecting the crc32 algorithm, otherwise ignored. Options are IEEE (default), Castagnoli and Koopman
Examples
root.h1 = this.value.hash("sha1").encode("hex")
root.h2 = this.value.hash("hmac_sha1","static-key").encode("hex")
# In: {"value":"hello world"}
# Out: {"h1":"2aae6c35c94fcfb415dbe95f408b9ce91ee846ed","h2":"d87e5f068fa08fe90bb95bc7c8344cb809179d76"}The crc32 algorithm supports options for the polynomial.
root.h1 = this.value.hash(algorithm: "crc32", polynomial: "Castagnoli").encode("hex")
root.h2 = this.value.hash(algorithm: "crc32", polynomial: "Koopman").encode("hex")

format_timestamp_unix
Attempts to format a timestamp value as a unix timestamp. Timestamp values can either be a numerical unix time in seconds (with up to nanosecond precision via decimals), or a string in RFC 3339 format. The ts_parse method can be used in order to parse different timestamp formats.
format_timestamp_unix_micro
Attempts to format a timestamp value as a unix timestamp with microsecond precision. Timestamp values can either be a numerical unix time in seconds (with up to nanosecond precision via decimals), or a string in RFC 3339 format. The ts_parse method can be used in order to parse different timestamp formats.
format_timestamp_unix_milli
Attempts to format a timestamp value as a unix timestamp with millisecond precision. Timestamp values can either be a numerical unix time in seconds (with up to nanosecond precision via decimals), or a string in RFC 3339 format. The ts_parse method can be used in order to parse different timestamp formats.
format_timestamp_unix_nano
Attempts to format a timestamp value as a unix timestamp with nanosecond precision. Timestamp values can either be a numerical unix time in seconds (with up to nanosecond precision via decimals), or a string in RFC 3339 format. The ts_parse method can be used in order to parse different timestamp formats.
parse_timestamp
Attempts to parse a string as a timestamp following a specified format and outputs a timestamp, which can then be fed into methods such as ts_format.
The input format is defined by showing how the reference time, defined to be Mon Jan 2 15:04:05 -0700 MST 2006, would be displayed if it were the value. For an alternative way to specify formats check out the ts_strptime method.
