Does any one know how to generate the possible misspelling ?
Example : unemployment
- uemployment
- onemploymnet
-- etc.
If you just want to generate a list of possible misspellings, you might try a tool like this one. Otherwise, in SAS you might be able to use a function like COMPGED to compute a measure of the similarity between the string someone entered, and the one you wanted them to type. If the two are "close enough" by your standard, replace their text with the one you wanted.
Here is an example that computes the Generalized Edit Distance between "unemployment" and a variety of plausible mispellings.
data misspell;
input misspell $16.;
length misspell string $16.;
retain string "unemployment";
GED=compged(misspell, string,'iL');
datalines;
nemployment
uemployment
unmployment
uneployment
unemloyment
unempoyment
unemplyment
unemploment
unemployent
unemploymnt
unemploymet
unemploymen
unemploymenyt
unemploymenty
unemploymenht
unemploymenth
unemploymengt
unemploymentg
unemploymenft
unemploymentf
blahblah
;
proc print data=misspell label;
label GED='Generalized Edit Distance';
var misspell string GED;
run;
Essentially you are trying to develop a list of text strings based on some rule of thumb, such as one letter is missing from the word, that a letter is misplaced into the wrong spot, that one letter was mistyped, etc. The problem is that these rules have to be explicitly defined before you can write the code, in SAS or any other language (this is what Chris was referring to). If your requirement is reduced to this one-wrong-letter scenario then this might be managable; otherwise, the commenters are correct and you can easily create massive lists of incorrect spellings (after all, all combinations except "unemployment" constitute a misspelling of that word).
Having said that, there are many ways in SAS to accomplish this text manipulation (rx functions, some combination of other text-string functions, macros); however, there are probably better ways to accomplish this. I would suggest an external Perl process to generate a text file that can be read into SAS, but other programmers might have better alternatives.
If you are looking for a general spell checker, SAS does have proc spell.
It will take some tweaking to get it working for your situation; it's very old and clunky. It doesn't work well in this case, but you may have better results if you try and use another dictionary? A Google search will show other examples.
filename name temp lrecl=256;
options caps;
data _null_;
file name;
informat name $256.;
input name &;
put name;
cards;
uemployment
onemploymnet
;
proc spell in=name
dictionary=SASHELP.BASE.NAMES
suggest;
run;
options nocaps;

I have different commands my program is reading in (i.e., print, count, min, max, etc.). These words can also include a number at the end of them (i.e., print3, count1, min2, max6, etc.). I'm trying to figure out a way to extract the command and the number so that I can use both in my code.
I'm struggling to figure out a way to find the last element in the string in order to extract it, in Smalltalk.
You didn't told which incarnation of Smalltalk you use, so I will explain what I would do in Pharo, that is the one I'm familiar with.
As someone that is playing with Pharo a few months at most, I can tell you the sheer amount of classes and methods available can feel overpowering at first, but the environment actually makes easy to find things. For example, when you know the exact input and output you want, but doesn't know if a method already exists somewhere, or its name, the Finder actually allow you to search by giving a example. You can open it in the world menu, as shown bellow:
By default it seeks selectors (method names) matching your input terms:
But this default is not what we need right now, so you must change the option in the upper right box to "Examples", and type in the search field a example of the input, followed by the output you want, both separated by a ".". The input example I used was the string 'max6', followed by the desired result, the number 6. Pharo then gives me a list of methods that match that:
To get what would return us the text part, you can make a new search, changing the example output from number 6 to the string 'max':
Fortunately there is several built-in methods matching the description of your problem.
There are more elegant ways, I suppose, but you can make use of the fact that String>>#asNumber only parses the part it can recognize. So you can do
'print31' reversed asNumber asString reversed asNumber
to give you 31. That only works if there actually is a number at the end.
This is one of those cases where we can presume the input data has a specific form, ie, the only numbers appear at the end of the string, and you want all those numbers. In that case it's not too hard to do, really, just:
numText := 'Kalahari78' select: [ :each | each isDigit ].
num := numText asInteger. "78"
To get the rest of the string without the digits, you can just use this:
'Kalahari78' withoutTrailingDigits. "Kalahari"6
As some of the Pharo "OGs" pointed out, you can take a look at the String class (just type CMD-Return, type in String, hit Return) and you will find an amazing number of methods for all kinds of things. Usually you can get some ideas from those. But then there are times when you really just need an answer!
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.
I have a dataset with data collected from a form that contains various date and value fields. Not all fields are mandatory so blanks are possible and
in many cases expected, like a DeathDate field for a patient who is still alive.
How do I best represent these blanks in the data?
I represent DeathDate using xsd:dateTime. Blanks or empty spaces are not allowed. All of these are flagged as invalid when validating using Jena RIOT:
foo:DeathDate_1
a foo:Deathdate ;
time:inXSDDatetime " "^^xsd:dateTime .
foo:DeathDate_2
a foo:Deathdate ;
time:inXSDDatetime ""^^xsd:dateTime .
foo:DeathDate_3
a foo:Deathdate ;
time:inXSDDatetime "--"^^xsd:dateTime .
I prefer to not omit the triple because I need to know if it was blank on the source versus a conversion error during construction of my RDF.
What is the best way to code these missing values?
You should represent this by just omitting the triple. That's the meaning of a triple that's "not present": it's information that is (currently) unknown.
Alternatively, you can choose to give it the value "unknown"^^xsd:string when there's no death date. The solution in this case is to not datatype it as an xsd:dateTime, but just as a simple string. It doesn't have to be a string of course, you could use any kind of "special" value for this, e.g. a boolean false - just as long as it's a valid literal value that you can distinguish from actual death dates. This will solve the parsing problem, but IMHO if you do this, you are setting yourself up for headaches in processing the data further down the line (because you will need to ask queries over this data, and they will have to take two different types of values into account, plus the possibility that the field is missing).
I prefer to not omit the triple because I need to know if it was blank
on the source versus a conversion error during construction of my RDF.
This sounds like an XY problem. If there are conversion errors, your application should signal that in another way, e.g. by logging an error. You shouldn't try to solve this by "corrupting" your data.
i´ve got small problem and before I spend even more time in trying to solve it i´d like to know if what I want to do is even possible ( and maybe input on how to do it^^).
My problem:
I want to take some text and then split it into different strings at every whitespace (for example "Hello my name is whatever" into "Hello" "my" "name" "is" "whatever").
Then I want to set every string with it´s own variable so that I get something alike to a= "Hello" b= "my" and so on. Then I want to compare the strings with other strings (the idea is to get addresses from applications without having to search through them so I thought I could copy a telephone book to define names and so on) and set matching input to variables like Firstname , LastName and street.
Then, and here comes the "I´d like to know if it´s possible" part I want it to put it into our database, this means I want it to copy the string into a text field and then to go to the next field via tab. I´ve done something like this before with AutoIT but i´ve got no idea how to tell AutoIT whats inside the strings so I guess it must be done through the programm itself.
I´ve got a little bit of experience with c++, python and BATCH files so it would be nice if anyone could tell me if this can even be done using those languages (and I fear C++ can do it and I´m just to stupid to do so).
Thanks in advance.
Splitting a string is very simple, there is usually a built in method called .split() which will help you, the method varies from language to language.
When you've done a split, it will be assigned to an array, you can then use an index to get the variables, for example you'd have:
var str = "Hello, my name is Bob";
var split = str.split(" ");
print split[0]; // is "Hello,"
print split[1]; // is "my" etc
You can also use JSON to return data so you could have an output like
print split["LastName"];
What you're asking for is defiantly possible.

I have a LaTeX document where I'd like the numbering of floats (tables and figures) to be in one numeric sequence from 1 to x rather than two sequences according to their type. I'm not using lists of figures or tables either and do not need to.
My documentclass is report and typically my floats have captions like this:
\caption{Breakdown of visualisations created.}
\label{tab:Visualisation_By_Types}
A quick way to do it is to put \addtocounter{table}{1} after each figure, and \addtocounter{figure}{1} after each table.
It's not pretty, and on a longer document you'd probably want to either include that in your style sheet or template, or go with cristobalito's solution of linking the counters.
The differences between the figure and table environments are very minor -- little more than them using different counters, and being maintained in separate sequences.
That is, there's nothing stopping you putting your {tabular} environments in a {figure}, or your graphics in a {table}, which would mean that they'd end up in the same sequence. The problem with this case (as Joseph Wright notes) is that you'd have to adjust the \caption, so that doesn't work perfectly.
Try the following, in the preamble:
\makeatletter
\newcounter{unisequence}
\def\ucaption{%
\ifx\#captype\#undefined
\#latex#error{\noexpand\ucaption outside float}\#ehd
\expandafter\#gobble
\else
\refstepcounter{unisequence}% <-- the only change from default \caption
\expandafter\#firstofone
\fi
{\#dblarg{\#caption\#captype}}%
}
\def\thetable{\#arabic\c#unisequence}
\def\thefigure{\#arabic\c#unisequence}
\makeatother
Then use \ucaption in your tables and figures, instead of \caption (change the name ad lib). If you want to use this same sequence in other environments (say, listings?), then define \the<foo> the same way.
My earlier attempt at this is in fact completely broken, as the OP spotted: the getting-the-lof-wrong is, instead of being trivial and only fiddly to fix, absolutely fundamental (ho, hum).
(For the afficionados, it comes about because \advance commands are processed in TeX's gut, but the content of the .lof, .lot, and .aux files is fixed in TeX's mouth, at expansion time, thus what was written to the files was whatever random value \#tempcnta had at the point \caption was called, ignoring the \advance calculations, which were then dutifully written to the file, and then ignored. Doh: how long have I know this but never internalised it!?)
Dutiful retention of earlier attempt (on the grounds that it may be instructively wrong):
No problem: try putting the following in the preamble:
\makeatletter
\def\tableandfigurenum{\#tempcnta=0
\advance\#tempcnta\c#figure
\advance\#tempcnta\c#table
\#arabic\#tempcnta}
\let\thetable\tableandfigurenum
\let\thefigure\tableandfigurenum
\makeatother
...and then use the {table} and {figure} environments as normal. The captions will have the correct 'Table/Figure' text, but they'll share a single numbering sequence.
Note that this example gets the numbers wrong in the listoffigures/listoftables, but (a) you say you don't care about that, (b) it's fixable, though probably mildly fiddly, and (c) life is hard!
I can't remember the syntax, but you're essentially looking for counters. Have a look here, under the custom floats section. Assign the counters for both tables and figures to the same thing and it should work.
I'd just use one type of float (let's say 'figure'), then use the caption package to remove the automatically added "Figure" text from the caption and deal with it by hand.
