kandi X-RAY | berry Summary
Berry is a ultra-lightweight dynamically typed embedded scripting language. It is designed for lower-performance embedded devices. The Berry interpreter-core's code size is less than 40KiB and can run on less than 4KiB heap (on ARM Cortex M4 CPU, Thumb ISA and ARMCC compiler). The interpreter of Berry include a one-pass compiler and register-based VM, all the code is written in ANSI C99. In Berry not every type is a class object. Some simple value types, such as int, real, boolean and string are not class object, but list, map and range are class object. This is a consideration about performance. Register-based VM is the same meaning as above.

QUESTION
How to update the selected item in the proper QLineEdit? 3 textboxes and filled by various sets of data. If I click some items in QListWidget, every time first QLineedit only updated. Instead of this, I want to update data to the corresponding QLineEdits. ( for Ex: if textbox1 is focused, then the selected item will update in textbox1. If textbox2 is focused, then the selected item will update in textbox2). But In My case, Every time textbox1 is only updated.

QUESTION
I'm trying to create a very simple easy game with multiple rounds and each round has three questions.
If you answer the wrong answer to a question in one round, you have to start the round again from the top. Once you have answered two questions correctly, you have a final question where if you answer this right you add 1 to the answer pot. After this you move on to the next round.
I am trying to figure out how to loop back to the start of the round that you are currently on if you get an answer wrong. At the moment if you get an answer wrong in the first round, you just go straight on into the second round.
Any ideas on how I can integrate a loop into the incorrect answer statements so they start that round again before they are able to move on? Thank you!
...ANSWER
Answered 2021-Jun-03 at 09:29A good way to solve this would be error handling - create a custom Exception and throw it whenever a wrong answer is given. Loop until you passed all questions without exception and then break.
I also modified your ask-function , there is no need for recursion in it, simply loop and return when a valid answer is given.

Answered 2021-Jun-01 at 00:26This should be a comment (as it's not an answer) but I need some formatting and a lot of space here. The short version is that you need to find out why git index-pack is misbehaving or failing. (Fetching over a smart protocol normally retrieves a so-called thin pack, which git fetch needs to "fatten" using git index-pack --fix-thin.)
The "invalid index-pack output" error occurs if the output from git index-pack does not match what git fetch-pack expects. Here's the code involved:

I'm try to loop 2 query inside one table . both query had 10 records . so i put my first foreach (or looping) before TR tag ..
here is example of the table that i want to create :
...ANSWER
Answered 2021-May-28 at 04:15Yep, your logic is missing something because the second loop is running within the first loop, so you're creating a lot of TDs within the same TR.
In order to achieve what you want, I suggest merging the two arrays, then looping a single array.
QUESTION
I have an equipment bookings register/calendar system that I am currently working on using Laravel.
Equipment can be booked out directly to staff as needed or scheduled for future dates. For example Laptop 1 might have three bookings but the laptop can only be booked out to one person at a time.
The system is up and running and the user can search for current/scheduled bookings. But I am having trouble allowing the user to search for the staff name as I need to split the query up.
As you can see I am first getting all of the devices from lines 7-14.
Then I am appending all of the bookings from each device to the $bookings collection in a new key called “available bookings”.
I am wondering how I can search the available bookings key for the staff_name field as I have already returned the eloquent queries as collections.

QUESTION
What is the Fastest strategy (in terms of Performance) to filter a combination of different type filters in jQuery?
In this example, I use "Radios + Select + Checkbox" and need them to operate together simultaneously.
JS Bin Link: https://jsbin.com/wegopom/3/edit?js,output
I am targeting markers in a Leaflet map based on the:
- image's "src" e.g. img[src$="marker-icon.png"] (ends with file name)
- image's "class" e.g. img.variation
Speed on the filter is central as this map will be displaying hundreds and eventually thousands of marker images.
For the Radios, ("variation" class)... I have a change function:

I think it's safe to say that the less conditions and the less selectors, the better performance (though we can't actually know without benchmarking).
To achieve this goal, you can work with classes only.
The following code is based on your jsbin, and it behaves in the following ways:
- It introduces three new classes:
variation,bottler,outage. - It utilizes filter-controllers values as class names parts (e.g., bottler's value
190is used to select the classbottler-190). - When two or more filters are selected (e.g., both variation and bottler), the intersection of those filters should be displayed.
- That's an important one. The reason your current code is buggy in some cases is that you handle each filter separately on its own handler, while actually, you must always consider all existing filters, on any
changeevent.

- It changes and shortens existing class names for convenience, better readbility, and easier maintenance.
- For example,
field-report-variation__12oz-cansis replaced with 'variation-12oz'.

- For better readability of this answer, I took the freedom to remove:
a. Unused classes (e.g.,tag-inside-marker).
b. Unused elements (e.g.,Fountain SURGEradio button).
Of course, they can be just returned back and used as needed.
Let me first show you the code, and I'll then lay out some notes and assumptions:
QUESTION
following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.
//.ts file
...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.
You can use the trim function to compare your value safely:
c.state.trim() == val.trim()

...ANSWER
Answered 2021-Apr-23 at 20:58In Flutter, the UI is the result of your state. So to change the UI, you'll need to handle state. Right now, all cells are always visible.
I would suggest changing the trees from just a String to an object with two properties, like 'name' and 'visible'.
