So I have this line on a page that provides a list of serial numbers as they are scanned in:
<div class='animate' ng-repeat='serialIdEntry in scan.scannedSerialIds track by $index'>
Presently each new scanned serial is appended to the bottom of the list, and it would be wildly more efficient and helpful were the order reversed.
Meaning, I need the most recent scan to be at top, and the whole of the list (as displayed) in reverse order.
I believe I can accomplish that by adding | orderBy:'':true" after the track by $index argument. Or by simply replacing that line with one that included the orderBy argument.
I suspect the method of updating on that page is AJAX/Angular, and I'm wondering how best to modify the output by way of a TamperMonkey script. I've been reading up on `waitForKeyElements', but that seems to largely speak to appending a new line of code rather than inserting a new snippet inline, or replacing a single line with one that has been modified.

I know gdb has several means of exploring data, some of them quite convenient. However, I cannot combine them to get that I need/want. I would like to display some custom string based on the first n values of a big array starting at <PT_arr>, and the last m values of the same array at a distance (in this case) 4096. Looking something like this:
table beginning:
0x804cfe0 <PT_arr>: 0x00100300 0x00200300 0x00300300 0x00400300
table end:
0x804cfe0 <PT_arr+4064>: 0x00500300 0x00600300 0x00700300 0x00800300
printf let's me add custom text (like table beginning)
the examine x gives me that nice alignment, let's me read many elements and group them by byte, words, etc; and shows addresses at the left (which is ideal for my case).
x aligns the content of regions of memory in an easy to read manner with the size and unit parameters. (what I want)
display is constantly printing. (what I want).
The issue with display (manual), is that unlike examine x (manual) it doesn't have a size or unit parameter.
Is there a way to accomplish that?
Thanks.
Suppose I have a long array.
> using MakieGallery
> size(database)
(210,)
If I do
> [d.title for d=database]
it will print it truncated, and if I show it, it will print it into a mess:
> show([d.title for d=database])
I don't know how, but probably I could print values into a column and it would scroll my console far up.
All this is bad. Is it possible to do some sort of simple "watch" of a variable? I.e. open some small widget in separate window with a list control, diplaying an array, which I could scroll as needed?
Internally Julia uses Base.show to display the values in the REPL, you can simply extend this function in any way you like (this example is just a really simple implementation to print every element of array in a new line and you probably shouldn't use it):
Base.show(io::IO, ::MIME"text/plain", x::Array) = x .|> println
You can then go on and add your function to .julia/config/startup.jl to load this every time you start the REPL. Just make sure to have a really solid implementation to handle various edge cases where it might not function properly.
Pluto.jl has a very nice viewer for tabular data (including arrays). It truncats the output per default, but offers a button to show more.
Furthermore, the view automatically updates when you change the data in another cell.
Someone decided to make a site as unfriendly as possible by intention so I'm trying what I can to have our scraper still get to where it should.
<div class="issueDetails">
<div class="issueTitle ng-binding" style="">FANCY UNIQUE TEXT dd.MM.yyyy</div>
<a>COMPLETELY DIFFERENT TEXT</a>
I've left out the unnecessary details here, but I'm trying to find a match within the site through XPATH (can't use anything else for this) that will find something which fulfils both conditions, FANCY UNIQUE TEXT dd.MM.yyyy *as well as COMPLETELY DIFFERENT TEXT.
I've tried my luck with //div[#class='issueDetails']/descendant::*[contains(text(), 'FANCY UNIQUE TEXT dd.MM.yyyy') and contains (text(), 'COMPLETELY DIFFERENT TEXT')]
but it contains the erroneous logic that both unique things I need are in the same thing.
The first, FANCY UNIQUE TEXT, is the unique identifier for where I want to go. The second, COMPLETELY DIFFERENT TEXT, is what I need the scraper to click on to actually head to that specific one. So an XPath that finds both despite them being different descendants is necessary.
Is this what you're looking for :
//div[#class="issueDetails"]/*[contains(.,"COMPLETELY DIFFERENT TEXT") or translate(substring(.,string-length(.)-9,10),"123456789","000000000")="00.00.0000" and contains(.,'FANCY UNIQUE TEXT')]
It will return the 2 elements respecting your conditions : div and a.
Translate, substring-length and substring functions are used to check if a date pattern is present in the div element.
EDIT : Check if the parent+child contains the text you're looking for, then get the childs with :
//div[#class='issueDetails'][contains(.,"FANCY UNIQUE TEXT dd.MM.yyyy") and contains(.,"COMPLETELY DIFFERENT TEXT")]/*[contains(.,"FANCY UNIQUE TEXT dd.MM.yyyy") or contains(.,"COMPLETELY DIFFERENT TEXT")]
Been looking all over the place for a solution to this issue. I have a Yahoo Pipe (http://pipes.yahoo.com/pipes/pipe.info?_id=e5420863cfa494ee40e4c9be43f0e812) that I've created to pull back image content from the Bing Search API. The URL builder includes a $skip attribute that takes an integer and uses it to select the starting (index) point for the result set that the query returns.
My initial plan had been to use the math engine in the Wolfram Alpha API to generate a random number (randomInteger[1000]) that I could use to seed the $skip value each time that the pipe is run. I have an earlier version of the pipe where I was able to get the query / result steps working using either "XPath Fetch" and "Fetch Data". However, regardless of how I Fetch the result, the response returns as an attribute / value pair in a list item.Even when I use "Emit items as string" in XPath Fetch, I still get a list with a single item, when what I really want is the integer that I can plug into my $skip attribute.
I've tried everything in Pipes I can think of, and spent a lot of time online looking for an answer. Is there anyway to extract text (in this case, a number) from a single list item and then use the output as input to "wire" a text parameter in another Pipes block? Any suggestions / ideas welcome. In the meantime, I'm generating a sorta-random number by manipulating a timecode hash, but it just feels tacky :-)
Thanks!
All the sources are for repeated items. You can't have a source that just makes a single number.
I'm not really clear what you're trying to do. You want to put a random number into part of the URL string that gets an RSS feed?
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')]
