kandi X-RAY | perk Summary
+--------------------------------------------------------+ | NOTE: I've moved development from googlecode to github | +--------------------------------------------------------+ See: git clone git://github.com/chrisdolan/perk.git. This is an implementation of the Java programming language. It is not intended to be an implementation of the Java virtual machine, however, so it will not be interoperable with existing JavaVM bytecode. The parser is heavily influenced by an ANTLR grammar for Java 1.5. From those roots, though, it's been modified to be more tightly coupled with Parrot and has been enhanced to support more syntax from the Java Language Specification, 3rd edition to parse a wider variety of Java sources (i.e. Java 1.6 and beyond).

QUESTION
I have been looking at solutions here and have been rewriting my code but I'm still having trouble getting it to work. I'd appreciate all and any help. Please bear in mind SQL is new to me!
I want to write a sql query that gets the record with the most likes (per likes column) and if there are multiple records with the same max likes then I only want the most recent record (per date column). Using the below table as an example, you can see I want row #4 because not only does it have max(Likes) but it's also more recent than row #1.
I tried the below but it returns nothing because it's trying to get a record that satisfies being both the newest and most liked in the table.
...ANSWER
Answered 2022-Apr-07 at 13:26You can use TOP 1
or LIMIT 1
(depending on DBMS) with ORDER BY
. Based on your sample data, something like this should work.

I'm following the Vue 3 documents on how to move to using the
This saves me having to declare each and every item in the object as its own ref(), removing boilerplate.
My question is, how can I achieve the same auto-destructuring in the mode of Vue, where it only detects top level declarations? I want to be able to reference the keys of the object directly, without having to use state.foo or state.bar, but not have to explicitly declare every single one as a const in order to make it available in the

Answered 2022-Mar-24 at 20:06You can destructure your object like you are doing and save the rest of the object keys and values with the spread operator.
QUESTION
I'm having trouble understanding the mechanism behind a typescript error I'm getting - I'm convinced there's something basic doing a "whoosh" sound as it flies over my head.
I've only found this question on the topic, but while the error looks the same, the setup seems quite different to me.
This is the definition I'm referencing, cut for brevity.
...ANSWER
Answered 2022-Mar-01 at 19:51There is a difference between (T | U)[]
and T[] | U[]
. In the first, each array element can be of type T or U. In the second (which corresponds with your case) the array can only have elements of one of either type.
The question you have to ask yourself is this: How can TypeScript know what elements are allowed when it doesn't know which type of an array a variable is?

I have being trying to update the data from/to Firebase, but i have some issue, and when i update the data, in the firestore, the fields are being set in null value. How can i fix?
he error is just ocorring in the Armas object, the rest data in AtributteData is fine.

Answered 2022-Feb-25 at 21:05You're using .set()
without explicitly telling it to merge existing fields with the new updates ones.
To fix it, tell Firestore to merge your new data with existing ones by passing SetOptions

QUESTION
It seems like this should be straightforward, but maybe it's not. Full disclosure: I am not a programmer by any stretch. I just know enough to muddle my way through hobby projects, and Pascal is brand new for me as of today. So, if anything is just really terrible code, I'm open to improvements. I'm probably only going to use this script once, though, so I'm not terribly concerned about optimization, just reliable operation.
I'm writing a script for xEdit, aka SSEEDit - the tool most people use for mucking around with Skyrim and Fallout 4 mods that don't make changes to rich game assets. The goal is to dump the raw text content of the DESC property for every BOOK object in the game (vanilla + original DLC). I've gotten pretty far and have a decent understanding of what I'm doing, but I cannot for the life of me get this part to work.
I have a blacklist of strings which should be skipped when iterating through all the BOOK objects. I've tried using pos()
several different ways, and it never comes back with anything other than zero.
The weird thing is, even if I can get a correct result from pos()
in testing, every book is a positive match when I run my actual script. It also doesn't seem like I'm actually iterating past the first entry in the blacklist.
Here's an example of what's returned when I search for a blacklist entry:
...ANSWER
Answered 2021-Dec-15 at 04:31Following the official Pascal documentation, the correct call of the pos
function is pos(SubString, SourceString)
. Moreover, I believe that the proper way to index TStringList
is blacklist[i]
.

QUESTION
I have a legacy Batch-File that starts up my application after doing some configuration. Trying to migrate to install4j i ran into the problem, that i cannot generate a launcher that only executes the batch file and gives me all the perks a generated launcher would offer.
The current (pretty ugly tbh) workaround is to package a separate executable jar that wraps the execution of the script and can be used by install4j to generate the launcher.
...ANSWER
Answered 2021-Nov-23 at 20:29You can use a custom installer application instead of a generated launcher. Under "Installer->Screens & actions", add an empty installer application and to its startup node add a "Run executable" action that starts the batch script.
QUESTION
I have been developing an app using HTML, CSS, and JS, using the App Mode command line argument for Google Chrome. It works nice, but I would like some ability to use the local file system without manual input from the user. That is, if I want a file accessed directly, I want it automatically done, not requiring the user to load the file in.
One option is to disable web security, which I'm not doing because there is a need to use Google Chrome normally. I haven't been able to use a command line argument to create a separate instance of Chrome, either.
I tried working on an HTA, but any attempt to port the code to HTA ends in headaches. Also, it doesn't seem to enjoy the perks that Blink/Webkit grants.
I looked into Electron and other similar platforms, and it requires installing a handful of things, which is a no-go due to the computer setup.
Are there any solutions with a sort of portable app, that can be dropped in a folder with the HTML document (say, labeled index.html or main.html), and upon opening the browser it directly opens that file without having to configure anything? A sort of barebones chromium-based browser that only opens a single file, allowing use of HTML, JS, CSS, along with local file access? Kind of like HTA but modern?
...ANSWER
Answered 2021-Oct-13 at 21:09The good news, is that it does exist, but it's not as "out-of-the-box" as HTA.
My team has migrated from HTA to WebView2.
The overall approach is to build a program with the WebView2 browser (you're basically building your own HTA like browser). Your javascript code can communicate back and forth with the program, which in turn has full access to local resources.
WebView2 is the Microsoft Edge Chromium browser, so you're getting the latest web tech and layouts (a big pain for HTA dev.). The program that contains the WebView2 control has full access to local files, scales, printers (without a pop-up dialog).
The approach has all the benefits of HTA (html / javascript programming, local file access, web based deployment, etc.), plus all layout and other benefits of a modern browser.
The program you'll build is very small, especially compared with the HUGE runtime of similar solutions, like Electron.
Rick Strahl has an excellent article on WebView2, and tips for building the program I'm describing. He has great advice on how to build an installer for it, including "Evergreen", which keeps the WebView2 up-to-date with the latest browser tech.

QUESTION
I am trying to save some quotes from a csv file to my django model using python manage.py shell
because I could not use django-import-export to do it. I asked about it at Tags imported but relationship not imported with django-import-export but nobody answered and I could not find more things to try after googling.
After reading the documentation and previous answers here about django querysets and tagging, I managed to save most of each quote but the tags are not saved. The query set does not return tags
field, which causes the AttributeError. Please see shell output q:
below
My tag model follows https://docs.wagtail.io/en/stable/reference/pages/model_recipes.html#custom-tag-models. From django-admin, the relationships are working. So the missing piece of the puzzle is saving the tags. What query should I use to locate the tags field or what method should I use to save the tags?
#The script I'm trying to run in python manage.py shell
ANSWER
Answered 2021-Sep-02 at 07:17Using Quote.objects.get(text__exact=row["text"].strip('"'))
works. I expected Quote.objects.filter(text__exact=row["text"].strip('"'))
to return 1 result and thought it should work but I was wrong.
I tested this in python manage.py shell
and it worked.
