Autocomplete|Typehead for Delimited String - user-interface

I'm trying to come up with a way to approach typehead in such a way that uniq substrings are given priority. For example, lets say I have the following:
foo.bar
foo.bar.baz
foo.bar.biz
foo.bar.bat
foo.bar.bat.art
foo.bar.bat.zap
...
foo.dog.alt
foo.dog.rar
...
foo.zed
foo.zed.rarg
Due to the drill down nature of the data, as the users types, the best thing to see what be the next unique option (since the list below the typeahead box would limited in length). So for example if someone where too type foo, they would see foo.bar, .foo.dog.alt, and foo.zed.
Any suggestions on how to approach this?

How to ignore "stop words" while sorting in MarkLogic?

Is there any way to ignore "stop words" while sorting.
For example:
I have words like
dixit
singla
the marklogic
On sorting in descending order the result should be
singla, the marklogic, dixit
As in the above example the is ignored.
Any way to achieve this?
Update:
Stop word can occur at any place.
for example
the MarkLogic
MarkLogic is the best
the MarkLogic is awesome
while sorting should not consider any stop word in the text.
Above is just a small example to describe the problem.
In actual I am using search:search API.
For sorting, I am using sort-order search options.
The element on which I have to perform sorting is dynamic. There are approx 30-35 elements.
Is there any way to customize the collation at this level like to configure some words (stop words) which will be ignored while sorting.
There is no standard collation URI that is going to do this for you (at least none that I've ever seen). You can do it dynamically, of course, by sorting on the result of a function invocation, but if you want it done efficiently at scale (and available to search:search), then you need to materialize the sortable string into your document. I've often done this as an attribute on the element:
<title sortable="Great Gatsby, The">The Great Gatsby</title>
Then you put a range index on the title/#sortable attribute.
You can also use the "envelope pattern" where materialized metadata like this is maintained in its own section of the document with the original kept in its own section. For things like this, I think it's a bit more elegant to decorate the elements directly, to keep the context.
If I understand your question correctly you're trying to get rid of the definite article when sorting your result-set.
In order to do this you need to use some additional functions and create a 'sort' criteria. My solution would look like this (I'm also including some sample documents so that you can test this just by copy-pasting):
(:
xdmp:document-insert("/peter.xml", <person><firstName>Peter</firstName><lastName>O'Toole</lastName><age>60</age></person>);
xdmp:document-insert("/john.xml", <person><firstName>John</firstName><lastName>Adams</lastName><age>18</age></person>);
xdmp:document-insert("/simon.xml", <person><firstName>Simon</firstName><lastName>Petrov</lastName><age>22</age></person>);
xdmp:document-insert("/mark.xml", <person><firstName>Mark</firstName><lastName>the Lord</lastName><age>25</age></person>);
:)
for $person in /person
let $sort := fn:reverse(fn:tokenize($person/lastName, ' '))[1]
order by $sort
(: return $person :)
return $person/lastName/text()
Notice that now the sort order is going to be
- Adams
- the Lord
- O'Toole
- Petrov
I hope this will help.

Xamarin UI Testing: search for elements "marked" with a string ignoring case and searching substring

Currently, when I use app.Tap I have to give it the exact string.
I want to do something like app.Tap("sstring") and still match elements marked with e.g. "somessting", "someSStRing", etc.
is it possible to have that somehow? it sounds like a simply thing, but I couldn't find a way to do it and it's surprising that there is no option to make it behave that way.
Have you tried doing it via the function overload and specifying the id?
app.Tap(e => e.Id("sstring"));
Marked searches many properties on each element to return any matches.

Protobuf: enum with default value

In google's Protocol Buffers, I use large enums and I have to assign each integer value explicitly:
enum Function {ProcessLibrary=0;
RotateLeft=1;
RotateRight=2;
...}
This is very annoying and ugly. Is there a way to avoid these integer values in the code?
something like:
enum Function {ProcessLibrary;
RotateLeft;
RotateRight;
...}
No, basically. This is deliberate to prevent huge errors when adding / removing enums, and to allow for non-contiguous enums.
In most real-world cases where the list of names is already defined elsewhere, you can write a 5 line script to add =n onto each - heck, a spreadsheet calculation and "fill down" would go a long way to it - paste names into the first column, copy the generated lines out of the second.

Retrieve an xpath text contains using text()

I've been hacking away at this one for hours and I just can't figure it out. Using XPath to find text values is tricky and this problem has too many moving parts.
I have a webpage with a large table and a section in this table contains a list of users (assignees) that are assigned to a particular unit. There is nearly always multiple users assigned to a unit and I need to make sure a particular user is assigned to any of the units on the table. I've used XPath for nearly all of my selectors and I'm half way there on this one. I just can't seem to figure out how to use contains with text() in this context.
Here's what I have so far:
//td[#id='unit']/span [text()='asdfasdfasdfasdfasdf (Primary); asdfasdfasdfasdfasdf, asdfasdfasdfasdf; 456, 3456'; testuser]
The XPath Query above captures all text in the particular section I am looking at, which is great. However, I only need to know if testuser is in that section.
text() gets you a set of text nodes. I tend to use it more in a context of //span//text() or something.
If you are trying to check if the text inside an element contains something you should use contains on the element rather than the result of text() like this:
span[contains(., 'testuser')]
XPath is pretty good with context. If you know exactly what text a node should have you can do:
span[.='full text in this span']
But if you want to do something like regular expressions (using exslt for example) you'll need to use the string() function:
span[regexp:test(string(.), 'testuser')]

Selecting random phrase from a list

I've been playing around with a .lua file which passes a random phrase using the following line:
SendChatMessage(GetRandomArgument("text1", "text2", "text3", "text4"), "RAID")
My problem is that I have a lot of phrases and the one line of code is very long indeed.
Is there a way to hold
text1
text2
text3
text3
in a list somewhere else in the code (or externally) and call a random value from the main code. Would make maintaining the list of text options easier.
For lists up to a few hundred elements, then the following will work:
messages = {
"text1",
"text2",
"text3",
"text4",
-- ...
}
SendChatMessage(GetRandomArgument(unpack(messages)), "RAID")
For longer lists, you would be well served to replace GetRandomArgument with GetRandomElement that would take a single table as its argument and return a random entry from the table.
Edit: Olle's answer shows one way that something like GetRandomElement might be implemented. But it used table.getn on every call which is deprecated in Lua 5.1, and its replacement (table.maxn) has a runtime cost proportional to the number of elements in the table.
The function table.maxn is only required if the table in use might have missing elements in its array part. However, in this case of a list of items to choose among, there is likely to be no reason to need to allow holes in the list. If you need to edit the list at run time, you can always use table.remove to remove an item since it will also close the gap.
With a guarantee of no gaps in the array of text, then you can implement GetRandomElement like this:
function GetRandomElement(a)
return a[math.random(#a)]
end
So that you send the message like this:
SendChatMessage(GetRandomElement(messages), "RAID")
You want a table to contain your phrases like
phrases = { "tex1", "text2", "text3" }
table.insert(phrases ,"text4") -- alternative syntax
SendChatMessage(phrases[math.random(table.getn(phrases))], "RAID")
Note: getn gets the size of the table; math.random gets a random number (with a max of the size of the phrases table) and the phrases[] syntax returns the table element at the index inside [].
