I utilise IntelliJ and not sbt.
I have a task where I need to create a post. I need to enter this information:
{
"packages": [
{
"uid": "...",
"x": 21.27,
"y": 23.36
},
{
"uid": "...",
"x": -16.01,
"y": -12.82
},
{
"uid": "...",
"x": 19.38,
"y": 1.77
}
],
"mailmen": [
{
"uid": "...",
"x": 14.68,
"y": 9.69
},
{
"uid": "...",
"x": 0.08,
"y": -3.34
}
]
}
And I've done the programm and I have classes:
class livreur(var uid:String,var xMaison:Double,var yMaison:Double,var x:Double,var y:Double,var distance:Double=0.0){
def afficherL : Unit ={
println("Uid "+uid)
println("Distance: "+distance)
}
}
class packages(var uid:String,var x:Double,var y:Double,var uidLivre:String=""){
def afficherP : Unit ={
println("Uid "+uid)
}
}
Functions which I utilise to create objects:
def saisirLivreur():livreur={
val uidLiv=readLine("Uid: ").toString
val xMaison=readLine("X: ").toDouble
val yMaison=readLine("Y: ").toDouble
return new livreur(uidLiv,xMaison,yMaison,xMaison,yMaison)
}
def saisirPackage():packages={
val uidPack=readLine("Uid: ").toString
val xPack=readLine("X: ").toDouble
val yPack=readLine("Y: ").toDouble
return new packages(uidPack,xPack,yPack)
}
**My questions are:
how I can connect my class with input information and how I can output the information in format which I need in the end if I have 2 ArraysBuffers, 1st with all couriers (livrMaison) and 2nd with all delivered packages (packagesLivré). :
[
{
"uid": "uid-du-livreur",
"tour": [ //liste des colis à distribuer, dans l'ordre
"uid-du-premier-colis-de-la-tournee-de-ce-livreur"
],
"length": 28.670242284303 //longueur totale du parcours
},
{
"uid": "uid-du-livreur",
"tour": [ //liste des colis à distribuer, dans l'ordre
"uid-du-premier-colis-de-la-tournee-de-ce-livreur",
"uid-du-second-colis-de-la-tournee-de-ce-livreur"
],
"length": 106.54693343859 //longueur totale du parcours
}
]

Please help me.
Thanks,-N
Classes in scala should be Upper case Livreur instead of livreur
to parse and produce json use one of existing libraries. I propose upickle (http://www.lihaoyi.com/upickle/) (add ibraryDependencies += "com.lihaoyi" %% "upickle" % "0.9.5" to build.sbt)

I'm using an API to return all Macros to me, I am trying to return all the "macros" where "actions" contains a "value" matching my Regexp Pattern which I will link below.
I've tried below and other methods, but it returns me nil for present values. Any tips appreciated
macros["value"].select { |m| m['key'] == 'value' }.first['/^DE([0-9a-zA-Z]\s?){20}$/gm']
API result snippet:
jsObj
=> {"macros"=>
[{"url"=>"https://s/1900002708354.json",
"id"=>1900002708354,
"title"=>"Append Signature",
"active"=>true,
"updated_at"=>"2021-10-22T14:11:15Z",
"created_at"=>"2021-10-22T14:11:15Z",
"position"=>10001,
"description"=>"This macro appends a signature to the message ",
"actions"=>[{"field"=>"comment_value_html", "value"=>"<p>Mit besten Grüßen,</p><p>{{current_user.name}} [{{ticket.account}}] <br></p><p><br></p><p>{{dc.signature_email}}<br></p><p><br></p>"}],
"restriction"=>nil},
{"url"=>"949.json",
"id"=>59071949,
"title"=>"information",
"description"=>nil,
"actions"=>[{"field"=>"priority", "value"=>"low"}, {"field"=>"comment_value", "value"=>"DE89370400440532013000" "DE89 3704
0044 0532 0130 00"
"}],
"restriction"=>nil},
Desired Result:
{
"macros": [
{
"url": "x.json",
"id": 1900002708354,
"actions": [
{
"field": "comment_value_html",
"value": "DE89 3704 0044 0532 0130 00"
}
],
"restriction": null
},
{
"url": "x.json",
"id": 59071949,
"actions": [
{
"field": "priority",
"value": "low"
},
{
"field": "comment_value",
"value": "DE89 3704 0044 0532 0130 00
"
}
],
"restriction": null
},
Given that macros is the JSON object containing the macros data, you can use
macros.select { |m| m["actions"].any? { |w| /\ADE(?:[0-9a-zA-Z]\s?){20}\z/.match?(w["value"]) } }
Here is a Ruby demo:
require 'json'
j = <<-DATA
{
"macros": [
{
"url": "x.json",
"id": 1900002708354,
"actions": [
{
"field": "comment_value_html",
"value": "DE11111111111222222220"
}
],
"restriction": null
},
{
"url": "x.json",
"id": 59071949,
"actions": [
{
"field": "priority",
"value": "low"
},
{
"field": "comment_value",
"value": "DE12345678901234567890"
}
],
"restriction": null
}
]}
DATA
jsObj = JSON.parse(j)
macros = jsObj['macros']
puts jsObj['macros'].select { |m| m["actions"].any? { |w| /\ADE(?:[0-9a-zA-Z]\s?){20}\z/.match?(w["value"]) } }
Output:
{"url"=>"x.json", "id"=>1900002708354, "actions"=>[{"field"=>"comment_value_html", "value"=>"DE11111111111222222220"}], "restriction"=>nil}
{"url"=>"x.json", "id"=>59071949, "actions"=>[{"field"=>"priority", "value"=>"low"}, {"field"=>"comment_value", "value"=>"DE12345678901234567890"}], "restriction"=>nil}
The .select { |m| m["actions"].any? { |w| /\ADE(?:[0-9a-zA-Z]\s?){20}\z/.match?(w["value"]) } } main part gets all actions nodes that contain an array with a value key whose value matches the regex given.
My original file is in CSV format which I have converted to python JSON array to JSON Sring.

You can use something like this to create the nested dict:
import json
def unflatten(somedict):
unflattened = {}
for key, value in somedict.items():
splitkey = key.split(".")
print(f"doing {key} {value} {splitkey}")
# subdict is the dict that goes deeper in the nested structure
subdict = unflattened
for subkey in splitkey[:-1]:
# if this is the first time we see this key, add it
if subkey not in subdict:
subdict[subkey] = {}
# shift the subdict a level deeper
subdict = subdict[subkey]
# add the value
subdict[splitkey[-1]] = value
return unflattened
data = {
"key": "timestamp",
"source": "eia007",
"turnover": "65million",
"url": "abc.com",
"record": "",
"loc.reg": "nord000",
"loc.count": "abs39i5",
"loc.town": "cold54",
"co.gdp": "nscrt77",
"co.pop.min": "min50",
"co.pop.max": "max75",
"co.rev": "",
"chain.system": "5t5t5",
"chain.type": "765ef",
"chain.strat": "",
}
unflattened = unflatten(data)
print(json.dumps(unflattened, indent=4))
Which produces:
{
"key": "timestamp",
"source": "eia007",
"turnover": "65million",
"url": "abc.com",
"record": "",
"loc": {
"reg": "nord000",
"count": "abs39i5",
"town": "cold54"
},
"co": {
"gdp": "nscrt77",
"pop": {
"min": "min50",
"max": "max75"
},
"rev": ""
},
"chain": {
"system": "5t5t5",
"type": "765ef",
"strat": ""
}
}

I'm trying to parse json file to csv. Could you help?
example json:
{
"expand": "schema,names",
"startAt": 0,
"maxResults": 50,
"total": 21,
"issues": [
{
"expand": "operations,versionedRepresentations",
"id": "217580",
"self": "issue/217580",
"key": "ART-4070",
"fields": {"summary": "#[ART] Pre.3 Verification \\"S\\""}
},
{
"expand": "operations,versionedRepresentations",
"id": "217579",
"self": "issue/217579",
"key": "ART-4069",
"fields": {"summary": "Verification \\"C\\""}
},
{
"expand": "operations,versionedRepresentations",
"id": "217577",
"self": "issue/217577",
"key": "ART-4068",
"fields": {"summary": "#[ART] Enum type"}
}
]
}
result csv should be like:
key;summary
ART-4070;#[ART] Pre.3 Verification \"S\"
ART-4069;Verification \"C\"
ART-4068;#[ART] Enum type
I've tried such a code:
import groovy.json.*
def jsonSlurper = new JsonSlurper()
def json = '''

},
{
"expand": "operations,versionedRepresentations",

}
]
}
'''
def obj = jsonSlurper.parse(json)
def columns = obj.issues*.keySet().flatten().unique()
// remove nulls
def encode = { e -> e == null ? '' : e }
// Print all the column names
println columns.collect { c -> encode( c ) }.join( ';' )
// create all the rows
println obj.issues.collect { row ->
// A row at a time
columns.collect { colName -> encode( row[ colName ] ) }.join( ';' )
}.join( '\n' )
but result is wrong:
expand;id;self;key;fields
operations,versionedRepresentations;217580;issue/217580;ART-4070;[summary:#[ART] Pre.3 Verification "S"]
operations,versionedRepresentations;217579;issue/217579;ART-4069;[summary:Verification "C"]
operations,versionedRepresentations;217577;issue/217577;ART-4068;[summary:#[ART] Enum type]
how can i extract only what i want from json file? I need only two columns:key,summary and values for them.
You want to extract only specific information from your list of issues
and you need different strategies to extract those. So I'd use
a "configuration" to describe the extraction (see the map config
below). Then the code is quite close to your original one (extracted
some common code etc)
import groovy.json.*
def config = [ // header -> extractor
"key": { it.key },
"summary": { it.fields.summary }
]
def encode(e) { // help with nulls; quote the separator
(e ?: "").replaceAll(";", "\\;")
}
def csvLine(items) { // write items as "CSV"
println(items.collect{ encode it }.join(";"))
}
// main
def obj = new JsonSlurper().parse("data.json" as File)
csvLine(config.keySet())
obj.issues.each{ issue ->
csvLine(config.values().collect{ f -> f issue })
}
I'm trying to use JsonBuilder with Groovy to dynamically generate JSON. I want to create a JSON block like:
{
"type": {
"__type": "urn",
"value": "myCustomValue1"
},
"urn": {
"__type": "urn",
"value": "myCustomValue2"
},
"date": {
"epoch": 1265662800000,
"str": "2010-02-08T21:00:00Z"
},
"metadata": [{
"ratings": [{
"rating": "NR",
"scheme": "eirin",
"_type": {
"__type": "urn",
"value": "myCustomValue3"
}
}],
"creators": [Jim, Bob, Joe]
}]
}
I've written:
def addUrn(parent, type, urnVal) {
parent."$type" {
__type "urn"
"value" urnVal
}
}
String getEpisode(String myCustomVal1, String myCustomVal2, String myCustomVal3) {
def builder = new groovy.json.JsonBuilder()
def root = builder {
addUrn(builder, "type", myCustomVal1)
addUrn(builder, "urn", "some:urn:$myCustomVal2")
"date" {
epoch 1265662800000
str "2010-02-08T21:00:00Z"
}
"metadata" ({
ratings ({
rating "G"
scheme "eirin"
addUrn(builder, "_type", "$myCustomVal3")
})
creators "Jim", "Bob", "Joe"
})
}
return root.toString();
}
But I've run into the following issues:
Whenever I call addUrn, nothing is returned in the string. Am I misunderstanding how to use methods in Groovy?
None of the values are encapsulated in double (or single) quotes in the returned string.
Anytime I use a {, I get a '_getEpisode_closure2_closure2#(insert hex)' in the returned value.
Is there something wrong with my syntax? Or can someone point me to some example/tutorial that uses methods and/or examples beyond simple values (e.g. nested values within arrays).
NOTE: This is a watered down example, but I tried to maintain the complexity around the areas that were giving me issues.
You have to use delegate in addUrn method instead of
passing the builder on which you are working.
It is because you are doing a toSting() or toPrettyString() on root instead of builder.
Solved if #2 is followed.
Sample:
def builder = new groovy.json.JsonBuilder()
def root = builder {
name "Devin"
data {
type "Test"
note "Dummy"
}
addUrn(delegate, "gender", "male")
addUrn(delegate, "zip", "43230")
}
def addUrn(parent, type, urnVal) {
parent."$type" {
__type "urn"
"value" urnVal
}
}
println builder.toPrettyString()
Output:-
{
"name": "Devin",
"data": {
"type": "Test",
"note": "Dummy"
},
"gender": {
"__type": "urn",
"value": "male"
},
"zip": {
"__type": "urn",
"value": "43230"
}
}
I try reading a JSON file from R using rjson but keep getting errors. I validated the JSON file using various online validators. Here is the content of the JSON file:

And the error:

Error in fromJSON(paste(readLines(json_file), collapse = "")) :
unexpected character: :
RJSON freaks out about empty arrays.
fromJSON( '{ "arr": [ ] }')
Error in fromJSON("{ \"arr\": [ ] }") : unexpected character: :
You can try the fromJSON function in the RJSONIO package hosted at http://www.omegahat.org. It seems to read the file fine.
There's a fix for this.
Create a new function to replace the existing getURL function used in RCurl and you should have your solution.
myGetURL <- function(...) {
rcurlEnv <- getNamespace("RCurl")
mapUnicodeEscapes <- get("mapUnicodeEscapes", rcurlEnv)
unlockBinding("mapUnicodeEscapes", rcurlEnv)
assign("mapUnicodeEscapes", function(str) str, rcurlEnv)
on.exit({
assign("mapUnicodeEscapes", mapUnicodeEscapes, rcurlEnv)
lockBinding("mapUnicodeEscapes", rcurlEnv)
}, add = TRUE)
return(getURL(...))
}
Test:
> json <- myGetURL("http://abicky.net/hatena/rcurl/a.json")
> cat(json, fill = TRUE)
{"a":"\\\"\u0030\\\""}
> fromJSON(json)
$a
