This is off-topic, as it's asking for recommendations. However, your VBA script may be optimisable, in which case Code Review could help. Otherwise, I'd look at exporting the data to Python and using it - search for reading Excel into Pandas, and it turns out there is a function for that. Try rewriting your VBA into Python, then ask here if you need help. — Ken Y-N 22 secs ago

@KamilCuk Let's not split hairs. We're using GitLab and it's code review feature, and that forces us to deal with the remote in certain ways. If we were using Gerrit instead, we'd get a different behaviour surrounding code review from the remote, and we would have different options. Also, the graphical interfaces do stuff, and sometimes it's easier to use those than to type stuff in my local terminal to effect changes. — gibson 55 secs ago

@SᴀᴍOnᴇᴌᴀ pretty sure you know your JS. Do you know if any of the cool new front-end web frameworks support multiple root elements? I want to modularize a local host website that is a mishmash of different projects. Notifications, tasks, quick links. None of them are related so no root is needed AFAIK. Or am I just being silly?

We’ll be performing some server maintenance on our Stack Exchange Data Explorer server starting at 2:00 PM UTC (10:00 am US/Eastern) on Tuesday, September 29, 2020. The service outage could be up to 12 hours. For more details, see our post on Meta Stack Exchange.

 
@Peilonrayz by "multiple root elements" do you mean child elements of a <body> element, such that one JS "controller" could reference those different child elements?
if it would help to prepare a fiddle you could try one on a site like jsfiddle.com, jsbin.com, codesandbox.io, plnkr.co, codepen.io, playcode.io etc...
 
I don't think so. You know when you use a web framework you have your root element <div id="app"></div> and then Vue, Angular.js do fun stuff under them
 
4:23 PM
right
I'm mostly familiar with AngularJS and VUe... have looked at ReactJS a little but not enough to know if it would do what you want
is it an issue like this?

@SᴀᴍOnᴇᴌᴀ I looked through that but I think it's solving a different problem. Might have to upgrade my Vue skill tho.
IIUC that's multiple roots of the same app. These would be different apps
I think I'll be able to monkey patch it with iframes at the worst, but not exactly the best go-to ;)
 
could you specify the <body> as the root element, then reference child elements by $refs?
do you want the framework code to simply read from those multiple root elements, or write to them (e.g. render HTML)?
 
@SᴀᴍOnᴇᴌᴀ That possibly would work but I fear it'd mean I'd have to merge all my projects into one.
 
if you merely just want to read from other parts of the page then you can just do DOM lookups...

Great input, thanks guys. Moving this questions to Code review Stack Exchange — Rachid Abadli 30 secs ago
 
@SᴀᴍOnᴇᴌᴀ It would be read/write but not between the apps. Otherwise I'd just scrap JS altogether and serve HTML from the server.
 
@Peilonrayz As your core or as an aside? Controller or viewer?
 
@RachidAbadli please read the help center pages like 'What topics can I ask about here?' and 'How do I ask a good question?_". In the current form the post would likely be close as off-topic because the code is not embedded directly, plus the title should describe what the code does instead of requesting review. — Sᴀᴍ Onᴇᴌᴀ 1 min ago
 
Sounds like it's already modular if it's a mish-mash of things.
Though not necessarily the modules you want :-)
 
@Peilonrayz can you give a sample objective you are trying to achieve?
 
4:38 PM
@Mast I don't understand what you mean by that. But they'd all be more like asides than a core. My MVC terminology skills aren't great. Pretty sure they'd just be views.
Yeah they're pretty modular but I kinda want them on the same page. Currently they're just fairly static stand alone sites
 
That makes sense.
 
@SᴀᴍOnᴇᴌᴀ I just want 2 Vue apps on one page really.
There wouldn't be any routes or views just really really dumb apps.
 
@Peilonrayz you should be able to have 2+ Vue instances on one page, plus multiple components
 
Oh, that's good. Sweet thanks :D
 
What will be the glue that keeps the 2 Vues together then?
 
4:45 PM
@Mast a common pattern is to use an Event bus
 
Flask and Jinja. I try to stay away from JS whenever at all possible. But I've had really nice times with Vue, AngularJS and Angular than I don't want to go anywhere near JQuery *shudder*
 
@SᴀᴍOnᴇᴌᴀ Heh, I didn't know that existed.
Then again, I don't know half of modern JS framework tricks.
At least.
 
@Mast yeah I wish it was in the documentation .... like the cookbook

@SᴀᴍOnᴇᴌᴀ I wasn't up until very recently, but a few days ago I took on a project for building a moderating website for monitoring the servers of a game I'm playing
It's not that I'm not a fan of programming side projects, but when I stop working I'd rather make time for my other passions :)
But this video game is worth it and I get to learn about React so I was like, you know what, let's go!
 
6:40 PM
@avazula yeah sometimes I feel the same way... nice
 
@SᴀᴍOnᴇᴌᴀ are you working on side projects these days?
 
honestly not really, mostly trying to improve front-end testing skills
 
oooh. Like behavioral testing and alike?
I still struggle to see how one would manage to have multiple levels on testing on the front end... But maybe that's because I'm biased by my backend/embedded software perspective
 
@avazula unit and e2e... e.g. with VueJS and its test-utils
 
There's at least unit-testing, automated testing, non-automated testing...
UX testing.
 
6:45 PM
woo, Vue, my favorite JS framework!
@Mast I see how to do these last two but I shall admit I struggle to see how to unit-test frontend code
 
Just like any code, in small pieces.
 
@CaptainObvious no query... which makes me believe it is CNWAI
Someday I would like to write tests like janos did for his voting system
I've also contemplated extending that code to show the reputation affect - might be a dopamine stimulator..
 
@Mast What's the difference between automated and unit tests? Cause my unit tests are pretty automated and Google seems to be 404 here
 
@Peilonrayz Thinking CI.
And yes, unit tests can be part of that.
 
Ah, that makes sense I guess git precommit hook would possibly also count?
You can set some up to not push secrets to git
 
6:53 PM
First of all, you should use Code Review Stack Exchange since there is no issue, so it's off-topic here. Secondly, Application.DoEvents is evil. Thirdly, if the file is huge, don't update the UI on every single line read, but use batches instead. Fourthly, reuse variables: don't do int.Parse(txt.Text) every single time. Lastly, we would need to know what's involved in the ProcessInsert constructor and InsertRow method for this to be on-topic in Code Review — Camilo Terevinto 57 secs ago
 
what is in your precommit hook? a linter, or do you run actual tests on it?
 
I don't have any precommit hooks. I'm guessing your point is that it has to be proper tests
 
I put my secret things in a seekrit folder and exclude it from merging.
Never put confidential things with your non-confidential things in the same file.
NEVER.

I use GitLab CI/CD variables and provider-stored secrets to pass confidential data to my pipelines
 
Oh yes, we've seen our fair share of API keys.
Provider-stored secrets, that basically means all the secrets are external, right?
Even if you'd just put a Seekrit class in a Seekrit folder holding your secrets, that works. A stupid container to be included, works.
 
@Mast Not come across the term before but I'd assume it's more like how CI + PyPI integrate
 
@Peilonrayz Could be, I'm not particularly good at setting such things up.
Once they work, I can maintain them. But setting them up is always a pain.
