local config = {
['dog'] = {amount = 500},
['dog'] = {amount = 600},
['dog'] = {amount = 700},
}
for k,v in pairs(config) do
print(v)
end
Output: table:0x244b890 - (500)
How to output all values from the table? Is it possible with the same keys?
I don't think it's possible, because in Lua tables, the keys are unique. So, I am afraid you have to use another way to represent your data.
local config = {
{ 'dog', amount = 500 },
{ 'dog', amount = 600 },
{ 'dog', amount = 700 }
}
for Index = 1, #config do
print(config[Index].amount)
end
The result will be:
500
600
700

I have a table that is generated by lua code and returned as a callback to client side, but the data is not ordered and I want to return a list sorted by id
local players = {}
for k, player in ipairs(QBCore.Functions.GetPlayers()) do
local charinfo = QBCore.Functions.GetPlayer(player).PlayerData.charinfo
local csn = QBCore.Functions.GetPlayer(player).PlayerData.citizenid
local playerjob = QBCore.Functions.GetPlayer(player).PlayerData.job.label
local ped = GetPlayerPed(player)
local playerCoords = GetEntityCoords(ped)
players[k] = {
["id"] = player,
["name"] = tostring(GetPlayerName(player)),
["charName"] = ("%s %s"):format(charinfo.firstname, charinfo.lastname),
["csn"] = csn,
["playerjob"] = playerjob,
["serverid"] = player,
["ped"] = GetPlayerPed(player),
["coords"] = playerCoords,
}
end
cb(players)
you can use table.sort to order your players table. this will sort the table in-place using the function you provide to determine the order.
table.sort is also explained in Programming in Lua: 19.3 – Sort
Here is an example based on your question:
players =
{
{id = 3217},
{id = 6716},
{id = 3432},
{id = 5575},
{id = 6124},
{id = 1156},
{id = 1789},
}
table.sort(players, function(p1,p2) return p1.id < p2.id end)
for k, v in ipairs(players) do
print(k, v.id)
end
Output:
1 1156
2 1789
3 3217
4 3432
5 5575
6 6124
7 6716
I have this structure:
$ArrayX = [8349310431,8349314513,......]
$ArrayY = [667984788,667987788,......]
$ArrayZ = [148507632380,153294624079,.....]
$range_map = $ArrayX.zip([$ArrayY.map(&:to_i),
$ArrayZ.map(&:to_i)].transpose).sort
puts $range_map ={[8349310431=>[667984788, 148507632380],
8349314513=>[667987788, 153294624079]}
I need the key to be compared with the rest of the keys and if the subtraction between keys is lower than 100, that key to print
I corrected your code also as per your need, and solved further,
$ArrayX = [8349310431,8349314513]
$ArrayY = [667984788,667987788]
$ArrayZ = [148507632380,153294624079]
$range_map = $ArrayX.zip([$ArrayY.map(&:to_i), $ArrayZ.map(&:to_i)].transpose).sort
$ArrayX = [8349310431,8349314513]
=> [8349310431, 8349314513]
$ArrayY = [667984788,667987788]
=> [667984788, 667987788]
$ArrayZ = [148507632380,153294624079]
=> [148507632380, 153294624079]
$range_map = Hash[$ArrayX.zip([$ArrayY.map(&:to_i), $ArrayZ.map(&:to_i)].transpose).sort]
=> {8349310431=>[667984788, 148507632380], 8349314513=>[667987788, 153294624079]}
keys = $range_map.keys
valid_keys = keys.select { |k| keys.detect { |x| (x-k).abs > 100 } }
$range_map.slice(*valid_keys)
If particular key is having difference more than 100 with one of rest of keys then it will be valid for filtering.
I'm using the google API ruby client and I want to implement some more complex analytics queries such as suggested in this document
https://developers.google.com/analytics/devguides/reporting/core/v3/common-queries
This document suggests that metrics can be supplied as a comma delimited string of multiple metrics but the API client only accepts an expression.
How can I query on multiple metrics in a single query? The ruby client appears only to accept an expression which generally consists of a single metric such as sessions or pageviews like this:
metric = Google::Apis::AnalyticsreportingV4::Metric.new(expression: 'ga:sessions')
If I remove "expression" and enter a list of metrics I just get an error.
Invalid value 'ga:sessions;ga:pageviews' for metric parameter.
Here is my solution, together with a generic method for reporting Google Analytics data:
This answer should be read in conjunction with https://developers.google.com/drive/v3/web/quickstart/ruby
analytics = Google::Apis::AnalyticsreportingV4::AnalyticsReportingService.new
analytics.client_options.application_name = APPLICATION_NAME
analytics.authorization = authorize
def get_analytics_data( analytics,

analytics_date_range_object.start_date = start_date
analytics_date_range_object.end_date = end_date
report_request_object.date_ranges = [analytics_date_range_object]
# report_request_metrics = []
report_request_object.metrics = []
metrics.each { |metric|
analytics_metric_object = Google::Apis::AnalyticsreportingV4::Metric.new
analytics_metric_object.expression = metric
report_request_object.metrics.push(analytics_metric_object) }
# report_request_object.metrics = report_request_metrics
unless dimensions.empty?
report_request_object.dimensions = []
dimensions.each { |dimension|
analytics_dimension_object = Google::Apis::AnalyticsreportingV4::Dimension.new

analytics_segment_definition_object.segment_filters = []
segments.each { |segment|
analytics_segment_metric_filter_object.metric_name = segment[:metric_name]
analytics_segment_metric_filter_object.comparison_value = segment[:comparison_value]
analytics_segment_metric_filter_object.operator = segment[:operator]
analytics_segment_filter_clause_object.metric_filter = analytics_segment_metric_filter_object
analytics_or_filters_for_segment_object.segment_filter_clauses.push(analytics_segment_filter_clause_object)

report_request_object.page_size = page_size
end
get_reports_request_object.report_requests = [report_request_object]
response = analytics.batch_get_reports(get_reports_request_object)
end
If using dimensions, you can report data like this:
response = get_analytics_data(analytics, VIEW_ID, metrics: ['ga:pageviews'], dimensions: ['ga:pagePath'], order_bys: ['ga:pageviews'], page_size: 25)
response.reports.first.data.rows.each do |row|
puts row.dimensions
puts row.metrics.first.values.first.to_i
puts
end
I have a buch of accounts stored in a string dictionary and i would like to count the number of accounts existing, so basicly a ".count" but to find the number of dictionaries created.
var dictionary: [String : [ String ]] = ["" : []]
let storeString = "StoreString"
func addUpdateArray(strings: [String], index: Int) {
let locator = storeString + index.description
dictionary[locator] = strings
}
addUpdateArray(["Account1", "Hy"], 1)
addUpdateArray(["Account2", "Hey"], 3)
and now I would like to see how many accounts are have created of the kind dictionary, is ther a way?
Something like this?
var accounts = [String:[String:String]]() // or whatever your structure is
accounts["Edmund"] = [
"amount": "23.87",
"curreny": "dollars"
]
accounts["Baldrick"] = [
"amount": "23.87",
"curreny": "dollars"
]
accounts["Percy"] = [
"amount": "87.00",
"curreny": "peso"
]
println(accounts.keys.array.count) // 3
If you have dictionary of dictionaries and you want to count the number of actual values inside, you can do it like this:
var accounts = [
"accountsGroup1" : ["account1", "account2", "account3", "account4"],
"accountsGroup2" : ["account1", "account2"],
"accountsGroup3" : ["account1", "account2", "account3", "account4"]
]
let accountsCount = accounts.values.map { $0.count }
let numberOfAllAccounts = reduce(accountsCount, 0) { $0 + $1 }
println(numberOfAllAccounts)
I'm just trying to get my head around a multidimensional array creation from a perl script i'm currently converting to Ruby, I have 0 experience in Perl, as in i opened my first Perl script this morning.
Here is the original loop:
my $tl = {};
for my $zoom ($zoommin..$zoommax) {
my $txmin = lon2tilex($lonmin, $zoom);
my $txmax = lon2tilex($lonmax, $zoom);
# Note that y=0 is near lat=+85.0511 and y=max is near
# lat=-85.0511, so lat2tiley is monotonically decreasing.
my $tymin = lat2tiley($latmax, $zoom);
my $tymax = lat2tiley($latmin, $zoom);
my $ntx = $txmax - $txmin + 1;
my $nty = $tymax - $tymin + 1;
printf "Schedule %d (%d x %d) tiles for zoom level %d for download ...\n",
$ntx*$nty, $ntx, $nty, $zoom
unless $opt{quiet};
$tl->{$zoom} = [];
for my $tx ($txmin..$txmax) {
for my $ty ($tymin..$tymax) {
push #{$tl->{$zoom}},
{ xyz => [ $tx, $ty, $zoom ] };
}
}
}
and what i have so far in Ruby:
tl = []
for zoom in zoommin..zoommax
txmin = cm.tiles.xtile(lonmin,zoom)
txmax = cm.tiles.xtile(lonmax,zoom)
tymin = cm.tiles.ytile(latmax,zoom)
tymax = cm.tiles.ytile(latmin,zoom)
ntx = txmax - txmin + 1
nty = tymax - tymin + 1
tl[zoom] = []
for tx in txmin..txmax
for ty in tymin..tymax
tl[zoom] << xyz = [tx,ty,zoom]
puts tl
end
end
end
The part i'm unsure of is nested right at the root of the loops, push #{$tl->{$zoom}},{ xyz => [ $tx, $ty, $zoom ] };
I'm sure this will be very simple for a seasoned Perl programmer, thanks! `
The Perl code is building up a complex data structure in $tl -- hash, array, hash, array:
$tl{$zoom}[i]{xyz}[j] = $tx # j = 0
$tl{$zoom}[i]{xyz}[j] = $ty # j = 1
$tl{$zoom}[i]{xyz}[j] = $zoom # j = 2
So I think the key line in your Ruby code should be like this:
tl[zoom] << { 'xzy' => [tx,ty,zoom] }
Note also that the root item ($tl) refers to a hash in the Perl code, while your Ruby code initializes it to be an array. That difference might cause problems for you, depending on the values that $zoom takes.
