kandi X-RAY | thor Summary
Thor is a simple and efficient tool for building self-documenting command line utilities. It removes the pain of parsing command line options, writing "USAGE:" banners, and can also be used as an alternative to the [Rake][rake] build tool. The syntax is Rake-like, so it should be familiar to most Rake users. Please note: Thor, by design, is a system tool created to allow seamless file and url access, which should not receive application user input. It relies on [open-uri][open-uri], which combined with application user input would provide a command injection attack vector. [rake]: [open-uri]:

QUESTION
First post ever, after lurking for some weeks. I'm currently attending a full-stack bootcamp and recently we got into Javascript (so I'm extremely green, please be patient...I'm trying to reskill myself in another industry). One of the HLTs that is giving me a particular headache is as follows:
You are tasked with creating re-usable methods that can be used throughout the business. The business needs you to create methods for mathematics operations. Follow the instructions below:
- Ask the user for a number with a prompt() and store the value in a variable called firstValue
- Ask the user for a second number with a prompt()and store that value in a variable called secondValue
- Ask the user for a third input with prompt()storing the value in a variable called operation. >Expected operations are: a.+This is the addition symbol, located next to the backspace key(hold shift) b.–This is the subtraction symbol, located next to number 0key (hold shift) c./This is the division symbol, a forward slash, located next to the full stop key d.*This is the multiplication symbol, a star, accessed by holding shift and pressing number 8 e.^This is the to-the-power-of symbol, known as a caretin programming, accessed by holding shift and pressing the number 6
- Write a method for the 5 operations listed above (one for each operation) that takes in both valuesand returns the result of the operation.a.For examplefunction multiplication(firstValue, secondValue) { return firstValue * secondValue;}
- Create a case-switch for evaluating the operation the user supplied, and depending on the value, execute the relevant function.
- Print out to consolefirstValue, operator, secondValue, an equal sign, and the answer: a.2 x 8 = 16 STRETCH CHALLENGE: Wrap the code in a continuous loop that only ends when the user responds to a prompt that asks them “would you like to do another calculation?”with their answer being “no”. STRETCH CHALLENGE: Change the above code to also include methods for processing sin, cos, and tan. You can use the methodsMath.sin(x), Math.cos(x), Math.tan(x)but be aware thatthe user only needs to supply a single value and the operation they wish to dowhen needing sin, cos, and tan!
I'm stuck even before attempting the stretch challenges (which I have no clue on how to do, but that's a problem for later) and looking online I couldn't find anything helpful (since most calculators employ HTML and CSS as well). Here below my two attempts at making the code work (I made multiple variations of both, trying to find a version that worked, but without any luck). I used some Shakespearean English, just to spice it up and to make it less boring. Also, it's called "Calculathor".
First attempt:

I updated from ruby 2.7.1 to 3.1.1, then removed Gemfile.lock and ran bundle update (it's on a dev branch, so I can throw it away if this is a bad idea, I just wanted to see if it would work).
bundle update succeeds, but when I start the server:
ANSWER
Answered 2022-Mar-19 at 10:21The problem is related to the Ruby 3.1 / Psych 4.x incompatibility described in this issue: https://bugs.ruby-lang.org/issues/17866
Ruby 3.0 comes with Psych 3, while Ruby 3.1 comes with Psych 4, which has a major breaking change (diff 3.3.2 → 4.0.0).
- The new YAML loading methods (Psych 4) do not load aliases unless they get the
aliases: trueargument. - The old YAML loading methods (Psych 3) do not support the
aliaseskeyword.
At this point, it seems like anyone, anywhere that wants to load YAML in the same way it worked prior to Ruby 3.1, need to do something like this:

Good morning people.
I'm trying to understand the error below but as I'm new to rails, I didn't quite understand. Does anyone have a light on what it could be?
I searched the internet but didn't find anything specific.
I searched on the internet but didn't identify anything, if anyone has seen it or has the link, you can send me and I'll see.
If you need any more information to help, let me know and I'll edit the post and add it, I don't know if there's anything else I could have already posted.
thank you for your help !!
...ANSWER
Answered 2022-Jan-21 at 13:34First of all, the message about DidYouMean is a deprecation warning not an error, it doesn't break your app. It means that usage of DidYouMean::SPELL_CHECKERS is deprecated and will be removed in a future version of ruby. In this case in Ruby 3.3. You shouldn't worry about it until you use versions that are lower than 3.3.
It's not your code that triggers the warning. It comes from a gem named Thor. The issue was solved in thor version 1.2.0. You can update the gem by calling bundle update thor.
The actual error comes from the bootsnap gem:

So I'm creating a simple MERN App, backend is working properly, but when working with useState hook in frontend is causing issues. what im trying to do is to fetch "users" data(an array of object with field username) from backend endpoints, and updating the users array which is a hook, but it only updates with the last itm of the incoming username and not list of all usernames!!
code for fetching and updating the hook:
...ANSWER
Answered 2022-Jan-07 at 09:03The issue is two-fold, first you are using Array.prototype.map to iterate an array but are issuing unintentional side-effects (the state updates), and second, you are enqueueing state updates in a loop but using standard updates, each subsequent update overwrites the previous so only the last enqueued update is what you see in the next render.
Use either a .forEach to loop over the data and use a functional state update to correctly update from the previous state.

I'm trying to make a program that has different players in an array assigned with random numbers. It is round-based, so every round the players are assigned new random numbers, and the player(s) with the lowest number is removed from the array.
Problem is that when iterating it doesn't remove the player with the lowest number from the array. It does however print out the player with the lowest number, but that's it...
I want it to remove the player or players and display their names each round till there is one left.

Install thor
On a UNIX-like operating system, using your system’s package manager is easiest. However, the packaged Ruby version may not be the newest one. There is also an installer for Windows. Managers help you to switch between multiple Ruby versions on your system. Installers can be used to install a specific or multiple Ruby versions. Please refer ruby-lang.org for more information.
