So, I'm developing an application in C and I need to sscanf a string.
+CPMS: \"ME\",18,255,\"ME\",18,255,\"ME\",18,255
I need to get the number between the first and second commas, 18 in this example, but it can be from 0 to 255.
I'm trying to create the placeholder to get this but I can't seem to make it work.
I've tried lots of thing, but I can't understand why:
sscanf(pointer, "+CPMS: \"%*s\",%d", &intPointer);
doesn't work.
Can anyone help me?
Thank you.
Well, I'm going to answer my own question.
sscanf(pointer, "+CPMS: \"%*2s\",%d", &intPointer);
It looks like I needed to put the number of characters to ignore.
Hope it help someone else.

I am building a vocabulary trainer with a GUI and am stuck with a Listbox.
The Listbox has several topics to choose from and it works as requested.
Now I am struggling, to combine/merge the listbox.selecteditems, to add some text to it and put it into a variable
I tried to merge it by using the following code:
$TopicAnswer = '$listBox.SelectedItems_Answer'
[void] $ListBox.Items.Add('Weekdays')
[void] $ListBox.Items.Add('Months')
[void] $ListBox.Items.Add('Numbers 1-10')
[void] $ListBox.Items.Add('Numbers 10-20')
So the idea is, that when I for example choose 'Weekdays', I would like to have a variable that will become 'Weekdays_Answer'
I have tried several ways but usually end up with the content:
$listBox.SelectedItems_Answer
instead of
Weekdays_Answer
The idea behind it is, that I have pairs of arrays, where I have a topic name together with the topic name answer. So as soon as I have chosen a topic, I want a new variable that has this specific name and ads the underscore Answer to it, so I have the pairing arrays together for my vocabulary training.
What am I doing wrong?
Thank you for your help and support,
Mike
Thanx to you, I was able to figure it out.
$TopicAnswer = $listbox.text+'_Answer'
It works on this way. Thank you very much for your hint. You might did a typo but it helped to solve the issue.
Thanx,
Mike
I'm quite new to ELK and Grok-filtering, and I'm struggling with parsing this particular pattern in my grok filter.
I've used the grok debugger to try and solve this, but although I like the tool, I just get confused by the custom patterns.
Eventually, I hope to parse lots of log files sent by filebeat to logstash, then send the parsed logs to elasticsearch and display with kibana or some similar visualization tool.
The lines that I need to parse follow the following pattern:
1310 2017-01-01 16:48:54 [325:51] [326:49] [359:57] Some log info text
The first four digits is a log type identifier, and will be used for grouping. I've called the field "LogLineID".
The date is formatted YYYY-MM-DD HH:MM:SS, and is parsed ok. I called the field "LogDate".
But now the problem begins. Within the square brackets, I have counters, formatted as MM:SS if you like. I cannot for the life of me find a way to sort these out, but I need to compare these times, hence I want to store them as minutes and seconds, not just numbers.
The first is a counter "TimeSpent",
the second is a counter "TimeStarted" and
the third is a counter "TimeSinceDown".
Then, last, comes the info text, which I've managed to grok with simply applying %{GREEDYDATA:LogInfo}.
I notice that the amount of minutes could be far higher than the standard 60 minutes within an hour, so I may be barking up the wrong tree here trying to parse it with date patterns such as TIMESTAMP_ISO8601, but then, I don't really know how else to do this.
So, I came this far:
%{NUMBER:LogLineID} %{TIMESTAMP_ISO8601:LogDate}
and were as mentioned able to (by cutting away the square bracket parts) to parse the log info text with
%{GREEDYDATA:LogInfo}
to create a field LogInfo.
But that's were I'm stuck. Could someone please help me figure out the rest?
Massive thanks in advance.
PS! I also found %{NUMBER:duration}, but it could as far as I could tell only parse timestamps with dot, not colon..
grok regex expression can help you solve the problem.
but first I wanna make sure that do you mean [325:51] [326:49] [359:57] are the three component that you wanna to fetch? And it will returns the result like :
TimeSpent: 325:51
TimeStarted: 326:49
TimeSinceDown: 359:57
were i get the point , you can use my ways in on of the following suggestions:
define your own custom pattern files and add the pattern in your file.
just use the expression in filter part of logstash conf file
hope it will helps you
Ah, there was a space.. Actually, I was misleading myself and everybody in my question, as it was not actually that log line that was causing problems. I just took the first one, not realizing where the problem really were, but the one causing problems had a space within the brackets as such: [ 42:31]. There are also some parts where there are two spaces, so the way I managed to solve this was to include a %{SPACE} between the \[ and the %{NUMBER}:
%{NUMBER:LogLineID} %{TIMESTAMP_ISO8601:LogDate} \[%{SPACE}%{NUMBER:TimeSpentMinutes}\:%{NUMBER:TimeSpentSeconds}\] \[%{SPACE}%{NUMBER:TimeStartedMinutes}\:%{NUMBER:TimeStartedSeconds}\] \[%{SPACE}%{NUMBER:TimeSinceDownMinutes}\:%{NUMBER:TimeSinceDownSeconds}\] %{GREEDYDATA:LogText}
I still haven't solved the merging of minutes and seconds, but this I can also handle in a later stage.
Thanks to Lin Don for showing an interest in my problem, and sorry for not replying sooner.
Hope the solution will help others (or even myself) if their stuck on the same kind of problem.
Note to myself: Read the logs more carefully before grok'ing.. :)
GAMS: I think I have a pretty simple question, however I'm stuck and was wondering if someone could help here.
A simplified version of my model looks like this:
set(i,t) ;
parameter price
D;
variable p(i,t)
e(i,t);
equations
Equation1
obj.. C=sum((i,t), p(i,t)*price);
Model file /all/ ;
Solve file minimizing C using MIP ;
Display C.l;
p(i,t) and e(i,t) are related:
Equation1 .. e(i,t)=e=e(i,t-1)+p(i,t)*D
Now I want to retrieve information from the solution: lets say I want to know at what t e(i,t) has a certain value for example --> e(i,t)= x(i) or otherwise formulated e(i,t=TD)=x(i) find TD, where x(i) thus is depending on i. Does anyone know how I can write this in to my GAMs model? To be clear I do not want to change anything about my solution and the model I have runs; I just want to retrieve this information from the solution given.
So far I tried a couple of thing and nothing worked. I think that this must be simple, can anyone help? Thank you!
Try something like this:
set i /i1*i10/
t /t1*t10/;
variable e(i,t);
*some random dummy "solution"
e.l(i,t) = uniformInt(1,10);
set find5(i,t) 'find all combinations of i and t for which e.l=5';
find5(i,t)$(e.l(i,t)=5) = yes;
display e.l,find5;
Hope that helps,

I'm looking to return the number of results found in an ajax fashion on Algolia instant search.
A little field saying something like "There are X number of results" and refines as the characters are typed.
I've read you utilise 'nbHits' but i'm unsure of how to go about it.. Being from a design background.
Thanks for help in advance.
The instantsearch.js stats widget shows the number of results and speed of the search. If you don't want to use the widget, I believe you can still use {{nbHits}} inside of your template wherever you want the number to print.
Very easy when you know how, Thanks for pointing me in the right direction Josh.
This works:
search.addWidget(
instantsearch.widgets.stats({
container: '.no-of-results'
})
);
I am new to python.I am posting here for the first time and I know question might be quite basic but problem is I can't figure out myself.
Lets say I have
List=[("a,"b"),("c","d"),("e","f")]
I want the user to enter one of the elements of one of the tuples as input and the other element is printed.Or more precisely I would say that just one of elements in List[x][0] is input and corresponding List[x][1] element is printed as output.I hope it makes sense.
Thanks!
Please check List in the question.I think you forgot a quote(") in the first tuple.[("a^here,"b"),("c","d"),("e","f")]
I think this might help you.
List=[("a","b"),("c","d"),("e","f")]
c=raw_input('ENTER A CHARACTER-')
for i in xrange(len(List)):
if c in List[i]:
ind=List[i].index(c)
print List[i][abs(ind-1)]
break
