Is there a way to get the next or previous tag in AwesomeWM Lua Config?
Reason :- I want to get the next or previous tag to set the focused clients tag to it and then move to the tag.
I know there is awful.tag.viewnext which moves to the next tag but unsure about how to get the tag it will move to to set this on a client.
Thanks in advance
Well... yes, there is a way, but there is not a completely trivial one.
First, let's look at the default config. What existing functionality has to get next/previous tags? That is the mouse wheel on the taglist:
https://github.com/awesomeWM/awesome/blob/7a759432d3100ff6870e0b2b427e3352bf17c7cc/awesomerc.lua#L160-L161
So, how does awful.tag.viewnext and viewprev get the next tag? These functions just call viewidx with an idx of 1 or -1, e.g.:
https://github.com/awesomeWM/awesome/blob/7a759432d3100ff6870e0b2b427e3352bf17c7cc/lib/awful/tag.lua#L1494
So, awful.tag.viewidx can do what we want. How does it do it?
It gets a table of all un-hidden tags, finds the index of the currently selected tag and then uses gears.math.cycle to compute the index of the tag with the requested offset.
https://github.com/awesomeWM/awesome/blob/7a759432d3100ff6870e0b2b427e3352bf17c7cc/lib/awful/tag.lua#L1452-L1469
For you, something like the following should do the trick:
function get_tag_at_offset(i, s)
s = screen[s or awful.screen.focused()]
local tags = s.tags
local showntags = {}
for _, t in pairs(tags) do
if not awful.tag.getproperty(t, "hide") then
table.insert(showntags, t)
end
end
for k, t in ipairs(showntags) do
if t == sel then
return showntags[gears.math.cycle(#showntags, k + i)]
end
end
end
The above function can be used like get_tag_at_offset(1) to get the next tag and with argument -1 for the previous. Where possible, I would recommend to also pass in a screen via the second argument.
Also, all of this is completely untested and just written on the spot. There could very well be typos and other mistakes in here.

A few weeks ago it came out of gamemaker 2.3, practically in the gamemaker language they changed the scripts into functions, but now after converting the files to be able to reopen them, I double-checked all the scripts and etc but anyway when I start it it remains a black screen, however it doesn't give me any compilation errors or whatever, what could be the problem?
Ps.
I might sound stupid, but if someone has the same program as me I can pass the project to them so they can see the scripts for themselves, so basically it's just the base and there is only the script to make the player walk and for collisions, I know that no one would want to waste time, but I ask the same
Its possible that your code is stuck in an infinite loop, here's an example of what that might look like:
var doloop = true
while(doloop == true){
x += 1
y += 1
}
the "doloop" variable is never changed within the while loop, so it is always equal to true and the loop never ends. Because the code never finishes looping, it can never get around to drawing anything, so you end up with a black screen. The easiest way to check for these is to put a breakpoint/debugging point at the beginning and just after every while/for/do/ect loop and debug it. e.g. (I am using asterisks "*" to represent breakpoints)
var doloop = true
* while(doloop == true){
x += 1
y += 1
}
*
When you get to one of the loops remove the first breakpoint and hit the "continue" button in the debugger. If it (it being the computer) takes an longer than it should to hit the second breakpoint (as in, you wait for a ten seconds to or two minutes (depends on how complex the code is) and it still hasn't hit the second breakpoint), then you should replace the breakpoint at the beginning of the loop to check and make sure it is still in there. If it is still in the loop, then that is likely where the code is getting stuck. Review the loop and everywhere any associated variables are set/changed, and you should be able to find the problem (even if it takes a while).
Majestic_Monkey_ and the commentors are correct: use the debugger. It's easy and it's your friend. Just place a red circle on the very first line of code that runs, and click the little bug icon and you can step through your code easily.
But to address your specific issue (or if anyone in the future has this issue): scripts have changed into files that can have many functions. Where you used to have
//script_name
var num = argument0 + argument1;
return num;
You would now have
function script_name(a, b) {
var num = a + b;
return num;
}
All you have to do is create a decleration for your new function:
function my_function_name(argument_names, etc...)
Then wrap all your old code in { }, and replace all those ugly "argument0" things with actual names. It's that easy. Plus you can have more than one function per script!
Hello I am getting a general run time error. This am working with preloaded drop downs and I have another one function before this that works just fine. but when it tries to run this I get the error.
I have tried with different properties like innertext, html id, ect.. but this get the same error.
Sub WebList(DropDown)
Set myPage=Browser("title:=.*").Page("title:=.*")
Set myWebList=Description.Create()
myWebList("micClass").value="WebList"
Set AllWebList=myPage.ChildObjects(myWebList)
totalWebList=AllWebList.count()
For i = 0 To totalWebList
If AllWebList(i).GetRoProperty("name") = DropDown Then
AllWebList(i).select ("GO")
wait(3)
Exit for
End If
Next
Set myPage = nothing
Set myWebList2 = Nothing
Set AllWebList2 = nothing
End Sub
I want the dropdown to be selected. Thanks for any help/suggestion. Also if I can improve on any lines to make it for dynamic and experienced coder, please do suggest them.
You have an error in your For loop, if there are no lists with the specified name you will access one more than actually exist. This is due to the fact that To in vbscript is inclusive and the index starts at 0. If the list is found the code works for me.
The For loop should be:
For i = 0 to totatlWebList - 1
Often in Jupyter I'd move to different parts of the notebook to look at something, and when I am done I want to jump back to where I was working on previously. Right now I'd have to navigate to the closest Markdown section (through the Jupyter Notebook Extensions) and move up or down to get to where I was. Is there a way to jump directly to the last cell that I have made an edit (preferably through keyboard shortcut)? Thanks!
Ideally this would be a built-in shortcut of course, but in the meantime:
Option 1: Custom JavaScript
If you get a browser extension like Custom JavaScript for Websites 2 (open-source), then you can use this code to record a stack of scroll position histories and jump backwards with Ctrl+Shift+X:
// Visit JupyterLab in browser and click the Custom JS browser extension icon and then paste this:
if(location.href.startsWith("http://localhost:8888/lab")) {
let scrollLocationsHistories = new Map();
let scrollBinHeight = 100;
window.addEventListener("keydown", (e) => {
let notebookEl = document.querySelector(".jp-mod-searchable .jp-NotebookPanel-notebook");
if(!scrollLocationsHistories.has(notebookEl)) scrollLocationsHistories.set(notebookEl, [])
let scrollLocationsHistory = scrollLocationsHistories.get(notebookEl);
if(e.ctrlKey && e.shiftKey && e.key === "X") {
if(scrollLocationsHistory.length > 0) {
e.preventDefault();
let origScrollPos = notebookEl.scrollTop;
notebookEl.scrollTo(0, scrollLocationsHistory.pop()*scrollBinHeight);
let newScrollPos = notebookEl.scrollTop;
if(Math.abs(origScrollPos-newScrollPos) < scrollBinHeight && scrollLocationsHistory.length > 0) {
notebookEl.scrollTo(0, scrollLocationsHistory.pop()*scrollBinHeight); // jump back again because last edit position was close to current position
}
console.log("Scroll History (newest locations at end):", scrollLocationsHistory.map(v => v*scrollBinHeight))
}
} else if(!e.ctrlKey && !e.shiftKey && document.activeElement.tagName.toLowerCase() === "textarea") {
let scrollBin = Math.round(notebookEl.scrollTop/scrollBinHeight);
if(scrollLocationsHistory[scrollLocationsHistory.length-1] !== scrollBin) {
scrollLocationsHistory.push(scrollBin);
if(scrollLocationsHistory.length > 500) scrollLocationsHistory = scrollLocationsHistory.slice(-250);
}
}
});
}
It's just an initial prototype, but it seems to work quite well so far. You may want to adjust it a bit - e.g. scrollBinHeight causes nearby edits that are within scrollBinHeight pixels of one another to not create a second history entry. You'll need to edit http://localhost:8888/lab to match the URL that you want to enable it on. If you're reading this long after I've written it, then you may also need to change document.querySelector(".jp-mod-searchable .jp-NotebookPanel-notebook") (i.e. the main scrolling element of the active notebook) in case they've updated the HTML class names, or HTML structure.
Option 2: Fold Often
Another possible option (which may be impractical depending on your use case) is to get used to folding cells that you're not currently working on. That makes it much easy to quickly scroll between cells that you're working on.
Option 3: Search Hack
If you're working on a particular cell but often have to jump to another one, you can add a comment like #vv (or any random easy-to-type string) to both of those cells and then whenever you need to jump between them, just press Ctrl+F and then Enter. The first time you do this you'll obviously need to type vv in the search box, but after that it'll be remembered (unless you use the search for another string). The disadvantage of this approach is that you need to "prune" the #vvs from cells that you're no longer working on.
echap to go to command mode, then Ctrl + z will undo your last change, which will bring the focus on the last edited cell. ctrl + y will redo the last modification.
(Only tested on python3 kernel)
EDIT Actually if you press ctrl + z just once, you only get the focus part, without modifying your cell. Then press enter to go to edit mode, which scrolls the page to the active cell.
I am running WYSIHTML5 to allow myself to enter email text and format it for sending as HTML. However when I view HTML of the formatted text I get classes associated with elements for Colors. This is expected behavior but since I need to send the output in an email hence I would like to have those colors to be in Inline CSS, since I cannot attach CSS files with the email like that. Example here
<span class="wysiwyg-color-green">Testing</span>
That is if I select green color for text: Testing. Is there any way to modify that green to become part of html itself like
<span style="color:green">Testing</span>
I have tried to search for this but could not find, so I am not asking without first looking for it. If anybody could please just point somewhere. Even a link to any guide to this, will do. I do not wish that you spend time writing code for me.
You could do it with php :
str_replace ( 'class="wysiwyg-color-green"', 'style="color:green"' ,$html)
You can do the same with javascript, altrough it's always safer to do everything server-side.
http://www.w3schools.com/jsref/jsref_replace.asp
Here's the javascript code I used but may be a good idea to heed Jean-Georges warning above:
replaceColorStylesWithInlineCss = function (htmlContents){
result = htmlContents.replace('class="wysiwyg-color-black"', 'class="wysiwyg-color-black" style="color:black"');
result = result.replace('class="wysiwyg-color-silver"', 'class="wysiwyg-color-silver" style="color:silver"');
result = result.replace('class="wysiwyg-color-gray"', 'class="wysiwyg-color-gray" style="color:gray"');
result = result.replace('class="wysiwyg-color-maroon"', 'class="wysiwyg-color-maroon" style="color:maroon"');
result = result.replace('class="wysiwyg-color-red"', 'class="wysiwyg-color-red" style="color:red"');
result = result.replace('class="wysiwyg-color-purple"', 'class="wysiwyg-color-purple" style="color:purple"');
result = result.replace('class="wysiwyg-color-green"', 'class="wysiwyg-color-green" style="color:green"');
result = result.replace('class="wysiwyg-color-olive"', 'class="wysiwyg-color-olive" style="color:olive"');
result = result.replace('class="wysiwyg-color-navy"', 'class="wysiwyg-color-navy" style="color:navy"');
result = result.replace('class="wysiwyg-color-blue"', 'class="wysiwyg-color-blue" style="color:blue"');
result = result.replace('class="wysiwyg-color-orange"', 'class="wysiwyg-color-orange" style="color:orange"');
return result
};
Note: I kept the wysiwyg styles in there because I'm saving to the db and want it to display properly in the wysihtml5 section when I load it again. DRY it up if you're clever.
(first question here, sorry if I am breaking a piece of etiquette)
My site is running on an eCommerce back end provider that I subscribe to. They have everything in classic ASP. They have a black box function called import_products that I use to import a given text file into my site's database.
The problem is that if I call the function more than once, something breaks. Here is my example code:
for blah = 1 to 20
thisfilename = "fullcatalog_" & blah & ".csv"
Response.Write thisfilename & "<br>"
Response.Flush
Call Import_Products(3,thisfilename,1)
Next
Response.End
The first execution of the Import_Products function works fine. The second time I get:
Microsoft VBScript runtime error '800a0009'
Subscript out of range: 'i'
The filenames all exist. That part is fine. There are no bugs in my calling code. I have tried checking the value of "i" before each execution. The first time the value is blank, and before the second execution the value is "2". So I tried setting it to null during each loop iteration, but that didn't change the results at all.
I assume that the function is setting a variable or opening a connection during its execution, but not cleaning it up, and then not expecting it to already be set the second time. Is there any way to find out what this would be? Or somehow reset the condition back to nothing so that the function will be 'fresh'?
The function is in an unreadable include file so I can't see the code. Obviously a better solution would be to go with the company support, and I have a ticket it in with them, but it is like pulling teeth to get them to even acknowledge that there is a problem. Let alone solve it.
Thanks!
EDIT: Here is a further simplified example of calling the function. The first call works. The second call fails with the same error as above.
thisfilename = "fullcatalog_testfile.csv"
Call Import_Products(3,thisfilename,1)
Call Import_Products(3,thisfilename,1)
Response.End
The likely cause of the error are the two numeric parameters for the Import_Products subroutine.
Import_Products(???, FileName, ???)
The values are 3 and 1 in your example but you never explain what they do or what they are documented to do.
EDIT Since correcting the vender subroutine is impossible, but it always works for the first time it's called lets use an HTTP REDIRECT instead of a FOR LOOP so that it technically only gets called once per page execution.
www.mysite.tld/import.asp?current=1&end=20
curr = CInt(Request.QueryString("current"))
end = CInt(Request.QueryString("end"))
If curr <= end Then
thisfilename = "fullcatalog_" & curr & ".csv"
Call Import_Products(3,thisfilename,1)
Response.Redirect("www.mysite.tld/import.asp?current=" & (curr + 1) & "&end=" & end)
End If
