Goal
I would like to see what is the time on page for user who is logged in. Eliminate from reports time, while user was not logged in.
To have ability to distinguish between time on page while user is not logged in and time on page while he is logged in.
Setup
Let's say we have:
Traffic variable User logged in as a prop1 where is true or false.
Traffic variable Time from previous event as a prop2 in seconds
eVar1 duplicating prop1 | expire after event5
eVar2 duplicating prop2 | expire after event5
event4 - User logged in
event5 - User logged out
Time between events
From an article about measuring time between events (https://experienceleaguecommunities.adobe.com/t5/adobe-analytics-questions/calculate-time-between-success-events/qaq-p/302787)
if (s.events && (s.events + ",").indexOf("event4,") > -1) {
s.prop2 = "start"
}
if (s.events && (s.events + ",").indexOf("event5,") > -1) {
s.prop2 = "stop"
}
s.prop2 = s.getTimeToComplete(s.prop2, "TTC", 0);
s.getTimeToComplete = new Function("v", "cn", "e", "var s=this,d=new Date,x=d,k;if(!s.ttcr){e=e?e:0;if(v=='start'||v=='stop')s.ttcr=1;x.setTime(x.getTime()+e* 86400000);if(v=='start'){s.c_w(cn,d.getTime(),e?x:0);return '';}if(v=='stop'){k=s.c_r(cn);if(!s.c_w(cn,'',d)||!k)return '';v=(d.getTime()-k)/1000;var td=86400,th=3600,tm=60,r=5,u,un;if(v>td){u=td;un='days';}else if(v>th){u=th;un='hours';}else if(v>tm){r=2;u=tm;un='minutes';}else{r=.2;u=1;un='seconds';}v=v*r/u;return (Math.round(v)/r)+' '+un;}}return '';");
Time spent overview
From adobe docs (https://docs.adobe.com/content/help/en/analytics/components/metrics/time-spent.html)
A “sequence” is a consecutive set of hits where a given variable
contains the same value (whether by being set, spread forward, or
persisted). For example, prop1 “A” has two sequences: hits 1 & 2 and
hit 6. Values on the last hit of the visit do not start a new sequence
because the last hit has no time spent. Average time spent on site
uses sequences in the denominator.
So I guess I will uses prop1 as a denominator for logged in user state to count time between event in prop2 properly.
Problem
I am not pretty sure, If this approach is enough to correctly measure time spent only while user is logged in. I would appreciate some hints, how to set up eVars correctly or if I understand sequence denominator correctly.
I also set up eVars with terminating event5, but I am not sure, If this leads to desired behavior.
If you also solve this problem before, please can you lead me, how you define your segment or condition in reports.
GetTimeBetweenEvents plugin should do a job. However, it seems like it was rewritten, I have found in documentation example calls also using Launch plugins extension:

I have an iPhone app, where I want to show how many people are currently viewing an item as such:
I'm doing that by running this transaction when people enter a view (Rubymotion code below, but functions exactly like the Firebase iOS SDK):
listing_reference[:listings][self.id][:viewing_amount].transaction do |data|
data.value = data.value.to_i + 1
FTransactionResult.successWithValue(data)
end
And when they exit the view:
listing_reference[:listings][self.id][:viewing_amount].transaction do |data|
data.value = data.value.to_i + -
FTransactionResult.successWithValue(data)
end
It works fine most of the time, but sometimes things go wrong. The app crashes, people loose connectivity or similar things.
I've been looking at "onDisconnect" to solve this - https://firebase.google.com/docs/reference/ios/firebasedatabase/interface_f_i_r_database_reference#method-detail - but from what I can see, there's no "inDisconnectRunTransaction".
How can I make sure that the viewing amount on the listing gets decremented no matter what?
A Firebase Database transaction runs as a compare-and-set operation: given the current value of a node, your code specifies the new value. This requires at least one round-trip between the client and server, which means that it is inherently unsuitable for onDisconnect() operations.
The onDisconnect() handler is instead a simple set() operation: you specify when you attach the handler, what write operation you want to happen when the servers detects that the client has disconnected (either cleanly or as in your problem case involuntarily).
The solution is (as is often the case with NoSQL databases) to use a data model that deals with the situation gracefully. In your case it seems most natural to not store the count of viewers, but instead the uid of each viewer:
itemViewers
$itemId
uid_1: true
uid_2: true
uid_3: true
Now you can get the number of viewers with a simple value listener:
ref.child('itemViewers').child(itemId).on('value', function(snapshot) {
console.log(snapshot.numChildren());
});
And use the following onDisconnect() to clean up:
ref.child('itemViewers').child(itemId).child(authData.uid).remove();
Both code snippets are in JavaScript syntax, because I only noticed you're using Swift after typing them.
I have a apple script program that I am programming and I want the text the user sends to open an application, But I keep getting error messages saying "Can't get application {"name_of_app"} of <>. The code I very simple and I cant figure out the problem
set deReturnedItems to (display dialog "How many spam messages?" with icon stop default answer "" buttons {"Quit", "OK"} default button 2)
set xpp to text returned of deReturnedItems
set theReturnedItems to (display dialog "How many spam messages?" with icon stop default answer "" buttons {"Quit", "OK"} default button 2)
set amt to the text returned of theReturnedItems
set daReturnedItems to (display dialog "Last thing, what should the spam message say?" default answer "" buttons {"Quit", "OK"} default button 2)
set msg to the text returned of daReturnedItems
repeat [amt] times
tell application [xpp]
activate
tell application "System Events"
keystroke [msg]
keystroke return
end tell
end tell
end repeat
Get rid of those square brackets. Don't use them for variables. Use underscores before and after if you must, like:
repeat _amt_ times
…
end
Also, you need to check to make sure your variable is an integer before you use it in the repeat block.
Incidentally, when you set a variable and then include it in brackets, that's applescript syntax for set the string to a list. For example:
set [x, y, z] to "123"
return x
-- returns "1", and y is set to "2", and z is set to "3"
I'm currently teaching myself the Dart language, and my first app doesn't seem to be working right. Here's the code that's causing trouble:
usrLoc = int.parse(query("#txtLoc").text);
When I try to run the app, it opens fine, but when I click the button that triggers this (and three other similar parses), the debugger stops and tells me "Source not found" for int._native_parse(), int._parse(), and int.parse().
Any help would be greatly appreciated.
The text property for the specified element #txtLoc returns an empty string.
The parse method requires that:
The source must be a non-empty sequence of base- radix digits, optionally prefixed with a minus or plus sign ('-' or '+').
You can specify an onError named argument in your call to parse, which takes a callback that handles the invalid input. E.g., if you want the parse call to return the value 42 for all invalid input, you can do this:
usrLoc = int.parse(query("#txtLoc").text, onError: (val) => 42);
If you really expect the element to have some text, you can store the result of query("#txtLoc").text into a separate variable and verify the value. It would also be interesting to check what the real element type is or which tag is marked with id #txtLoc.
If you want to get the content of an input element, you should use the value property instead of text:
query("#txtLoc").value
I'm trying to get tab complete within all open buffers and yasnippet to both work with the tab key. At the moment I can have one or the other. The following code is how I'm handling the yasnippet expand, but as I'm not a lisp programmer I cannot see the mistake here.
If it cannot expand the snippet I would like it to try and expand from the buffer.
;; Auto complete settings / tab settings
;; http://emacsblog.org/2007/03/12/tab-completion-everywhere/ <-- in the comments
(global-set-key [(tab)] 'smart-tab)
(defun smart-tab ()
"This smart tab is minibuffer compliant: it acts as usual in
the minibuffer. Else, if mark is active, indents region. Else if
point is at the end of a symbol, expands it. Else indents the
current line."
(interactive)
(if (minibufferp)
(unless (minibuffer-complete)
(dabbrev-expand nil))
(if mark-active
(indent-region (region-beginning)
(region-end))
(if (looking-at "\\_>")
(unless (yas/expand)
(dabbrev-expand nil))
(indent-for-tab-command)))))
First, I try to understand what the code does, and what you would like it does.
Your code
first checks if the point is in the minibuffer.
If so, then it tries to complete the minibuffer
if (in minibuffer) cannot complete it, it calls dabbrev-expand
else if the point is not in minibuffer
if some region is marked , it indents the region.
if no mark is active, it checks to see if the point is at the end of some word
if so, it checks is yasnippet can expand.
if yas cannot expand, it calls dabbrev-expand
if not, it tries to indent the current line
This is what your code does.
Your code fails due to yas/expand. This command does not return in case the expansion fails.
In case that this command fails, it checks the state of the variable yas/fallback-behavior. If this variable has the value call-other-command, as in your case, the failed yas expansion calls the command bound to the key kept in the variable yas/trigger-key.
In your case , this variable is TAB.
So: You are at the end of the word, You press TAB to complete it, this triggers the interactive smart-tab, which calls yas/expand which in case it fails to expand calls the bound function of TAB, and here is the infinite loop.
The Solution for your problem is to temporaily bound nil to yas/fallback-behavior in this smart-tab function.
Here is how to fix it:
(if (looking-at "\\_>")
(let ((yas/fallback-behavior nil))
(unless (yas/expand)
(dabbrev-expand nil)))
(indent-for-tab-command))
