I have a set of data that is generated:
=((E31/320)^2)/(2+(E31/380))
=((E32/320)^2)/(2+(E32/380))
=((E33/320)^2)/(2+(E33/380))
...
I want to create a sum of these, but I don't want to just SUM them together; I want to write a function that put these together. I came up with this row:
=SUMPRODUCT(((ROW(E1:INDEX(E31:E63;C34)))/320)^2/(2 + (E31:E63/380)))
The problem with this line is it seems to overdo the whole thing. I need to somehow use one variable for the both E31:E63 intervals, because it will otherwise loop through the second E31:E63 n-times, instead of using the same value.
As I see it, there are two solutions.
Write the data in columns, but using the first solution
Write the function, but try to find something that makes the two E31:E63 work as one variable.
I want to implement the second option.
I believe
=SUMPRODUCT(((E31:E63/320)^2)/(2+(E31:E63/380)))
Will do what you want.

This might be a simple fix I'm unsure. I have the following formula which I would like to be able to drag up and down =IF(C311>B311,IF(C310>B310,IF(B309>C309,IF(C312>B312,2,1),0),0),0)
I'm guessing AND can be implemented in some way but I'm not sure. The logic behind my goal is if C311>B311 AND C310>B310 AND B309>C309 then check to see if C312>B312 if it is then put a 2 else put a 1. Perhaps there is another solution as well I'm not thinking of.
Try this: =IF(AND(C311>B311,C310>B310,B309>C309),IF(C312>B312,2,1),"")
Last argument I left it as "" but replace it to whatever you need.
Just another approach-
=IF((C311>B311)*(C310>B310)*(B309>C309),IF(C312>B312,2,1),"")
I have step where I am have String Array, something like this:
Then Drop-dow patient_breed contains ['Breed1', 'Breed2',.... Breed20']
I need to split this text on two lines. I know that in Gherkin there is expression """. I try something like this:
Then Drop-dow patient_breed contains ['Breed1',
"""
'Breed2',.... Breed20']
"""
It didn't help. Is there any solution?
What do you gain by putting this string in your scenario. IMO all you are doing is making the scenario harder to read!
What do you lose by putting this string in your scenario?
Well first of all you now have to have at least two things the determine the exact contents of the string, the thing in the application that creates it and the hardcoded string in your scenario. So you are repeating yourself.
In addition you've increased the cost of change. Lets say we want our strings to change from 'Breedx' to 'Breed: x'. Now you have to change every scenario that looks at the drop down. This will take much much longer than changing the code.
So what can you do instead?
Change your scenario step so that it becomes Then I should see the patient breeds and delegate the HOW of the presentation of the breeds and even the sort of control that the breeds are presented in to something that is outside of Cucumber e.g. a helper method called by a step definition, or perhaps even something in your codebase.
Try with a datatable approach. You will have to add a DataTable argument in the stepdefinition.
Then Drop-dow patient_breed contains
'Breed1'
'Breed2'
...
...
...
'Breed20']
For a multiline approach try the below. In this you will have to add a String argument to the stepdefinition.
Then Drop-dow patient_breed contains
"""
['Breed1','Breed2',.... Breed20']
"""
I would read the entire string and then split it using Java after it has been passed into the step. In order to keep my step as a one or two liner, I would use a helper method that I implemented myself.
First and foremost, I'm not familiar with Perl at all. I've been studying C++ primarily for the last 1/2 year. I'm in a class now that that is teaching Linux commands, and we have short little topics on languages used in Linux, including Perl, which is totally throwing me for a loop (no pun intended). I have a text file that contains a bunch of random numbers separated by spaces and tabs, maybe even newlines, that gets read into the program via a filehandle. I'm supposed to write 2 lines of code that split the lines of numbers and merge them into one array, inside of a foreach loop. I'm not looking for an answer, just a nudge in the right direction. I've been trying different things for multiple hours and feel totally silly I can't get it, I'm totally lost with the syntax. Its just a bit odd not working inside a compiler and out of my comfort zone working outside of C++. I really appreciate it. I've included a few photos. Basically, the code we are writing it just to store the numbers and the rest of the program will determine the smallest number and sum of all numbers. Mine is currently incorrect because I'm not sure what to do. In the output photo, it will display all the numbers being entered in via the text file, so you can see them.
Several things to fix here. First of all, please don't post screenshots of your sample data or code, as it makes it impossible to copy and paste to test your code or data. Post your code/data by indenting it with four spaces and a newline preceding the code block.
Add use strict; in your script. This should be lesson 0 in your class. After that add my to all variable declarations.
To populate #all_numbers with contents of each line's numbers, without using push, you can use something like this:
foreach my $line (#output_lines)
{
my #numbers = split /\s/, $line;
#all_numbers = (#all_numbers, #numbers);
}
You say you're "not looking for an answer," so here's your nudge:
You're almost there. You split each line well (using split/\s/) and store the numeric values in #all_numbers. However, notice that each time around in the loop, you replace (using the assignment, #all_numbers = ...) the whole contents of #all_numbers with the numbers you found in the current line. Effectively, you're throwing away everything you've stored from the previous lines.
Instead, you want to add to #all_numbers, not replace #all_numbers. Have a look at the push() function for how to do this.
NB: Your split() call is fine, but it's more customary to use split(' ', $line) in this case. (See split(): you can use a single space, ' ', instead of the pattern, /\s/, when you want to split on any whitespace.)
I hope you need to store the all splitting element into array, so you looking for push function.
foreach $line (#input_lines)
{
push(#all_numbers,split(/\s/,$line));
}
Your problem is, in every iteration, the splitted value is over written in an array not to append together. For example,
#array = qw(one two three);
#array = qw(five four seven);
print "#array";
output is five four seven not the one two three five four seven because this is reinitialize with a new values. You want to append the new values in the array in before or after use unshift or push
for example
#array = qw(one two three);
push(#array,qw(five four seven));
Another way:
my #all_numbers = map { split ' ', $_ } #output_lines;
See http://perldoc.perl.org/functions/map.html
Lets say that there is a function in my Delphi app:
MsgBox
and there is a string which has MsgBox in it.
I know what most of you are going to say is that its possible, but I think it is possible because I opened the compiled exe(compiled using delphi XE2) using a Resource Editor, and that resource editor was built for Delphi. In that, I could see most of the code I wrote, as I wrote it. So since the variables names, function names etc aren't changed during compile, there should a way to execute the functions from a string, but how? Any help will be appreciated.
EDIT:
What I want to do is to create a simple interpreter/scripting engine. And this is how its supposed to work:
There are two files, scr.txt and arg.txt
scr.txt contains:
msg_show
0
arg.txt contains:
"Message"
And now let me explain what that 0 is:
First, scr.txt's first line is function name
second line tells that at which line its arguments are in the arg.txt, i.e 0 tells that "Message" is the argument for msg_show.
I hope my question is now clear.
I want to make a simple scripting engine.
In order to execute arbitrary code stored as text, you need a compiler or an interpreter. Either you need to write one yourself, or embed one that already exists. Realistically, the latter option is your best option. There are a number available but in my view it's hard to look past dwscript.
I think I've already solved my problem! The answer is in this question's first answer.
EDIT:
But with that, as for a workaround of the problem mentioned in first comment, I have a very easy solution.
You don't need to pass all the arguments/parameters to it. Just take my example:
You have two files, as mentioned in the question. Now you need to execute the files. It is as simple as that:
read the first line of scr.txt
check if it's a function. If not, skip the line
If yes, read the next line which tells the index where it's arguments are in arg.txt
pass on the index(an integer) to the "Call" function.
Now to the function which has to be executed, it should know how many arguments it needs. i.e 2
Lets say that the function is "Sum(a,b : integer)".It needs 2 arguments
Now let the function read the two arguments from arg.txt.
And its done!
I hope it will help you all.
And I can get some rep :)
Consider the following statement:
process.text.readLines[3..<-1]
It seems like it should work. Essentially, strip off the first two elements of the array. However, the range operator is confused by the ending -1, since its less than -1. You can easily solve this problem by storing the array as a variable and replacing -1 with size() but that requires an extra line and the definition of a variable. Any other ideas how to express this easily?
I believe you could do:
process.text.readLines()[ 2..-1 ]
or:
process.text.readLines().drop( 2 )
This will also do the trick:
process.text.readLines().with { it[2..size()-1] }
It's longer than simply calling drop as suggested above, but it might read a little better depending on the larger context. with lets you get around defining a new variable.
