clap | CLI based music player for Windows | Runtime Evironment library

kandi X-RAY | clap Summary
This project was done as part of CBSE project work for 12th grade finals. The standard is C++17. The primary focus of the project was not limited to creating a music player but was also towards utilizing the various features of the programming language and thereby gaining a good exposure with it. This is a CLI based program which can play and manage WAVE files (others are either proprietary or use complex encoding, so we did not support them since this is a school project). This is a multi-source project which uses various OOP methodologies. We perform R/W operations on binary files, operator and function overloading, serialization, memory management, exit handling, use DLLs and callbacks, Windows API, limited the use of non ANSI code, optimized UI, optimized performance, multithreading, use of configuration file, better PRNGs and other algorithms, bitmasks, etc. We also created a data structure similar to std::deque to store the play queue (we didn't know of std::dequeue until we were halfway through the project, and due to lack of time, we didn't include it) in which we can insert or remove nodes from any end. It is the Queue class, which was fun designing (It crashed many systems because of simple bugs). The Player class inherits the queue from the Queue class. We found out while coding that OOP is not a simple task and requires a good amount of brainwork and skill.

QUESTION
Playing with Rusts clap crate for the first time. And I wonder how to use the default value of a command line option, when the option was not specified at the command line.
Given I specified a default_value in the yaml file (see snippet below), I expected
the matches.value_of("VERBOSE") to return the default value if there is no other value
given in the command line.
Instead, I get:
thread 'main' panicked at 'called
Option::unwrap()on aNonevalue', src/main.rs:18:6
I was googling for a while but it seems, no one really gives a canonical example of how it is supposed to work.
...ANSWER
Answered 2021-Apr-22 at 05:00The problem is you either have a small misconception about what value_name (which is used only for the CLI help option) is, or you missed, that the argument names are case sensitive.
You have two options to make this work as expected:
- Use the lowercase argument name as specified in the YAML (change .rs):

You can see in the following code snippet that I had to manually type all possible string options for GIF. But I guess there must be a better way to achieve this. Anybody can help me with this?
...ANSWER
Answered 2021-Apr-18 at 09:26The fewest changes to your code that would work is probably to define gifs as a separate constant, and get the keys from it with keyof typeof gifs.

Answered 2021-Mar-30 at 07:50In the dependencies section you are specifying clap-v3 as a dependency which you need to use like use clap_v3; in your code.
Maybe you wanted to add clap (without -v3) as a dependency. It has a release with the same version number.
QUESTION
newbie here, so apologies if this is a stupid question.
I would like to use the functionality of the wagyu crate in my code. This crate has command line functionality, so I can run the code from the command line but I can't seem to reference it from my own code.
I've tried 2 options:
- Replicate the input 'clap' is expecting when calling the crate (a struct with arguments)
- Call a specific function from within the crate
For item 2 I have tried:

QUESTION
My friend wrote this amazing code for me but it doesn't seem to work. It's meant to send a message on a command then edit the message over and over again. But when I run the code my terminal says
DiscordAPIError: Cannot edit a message authored by another user method: 'patch', path: '/channels/808300406073065483/messages/811398346853318668', code: 50005, httpStatus: 403
Is there a way to fix this problem?
...ANSWER
Answered 2021-Feb-22 at 07:00The Channel#send() method returns a promise, meaning you must wait for the action to finish before being able to define it. This can be done using either .then() or async and await. From personal preference, I regularly use the second option, although I have laid both options out for you.
QUESTION
In the following Main method why isn't the last word (clapping) removed?
ANSWER
Answered 2021-Feb-18 at 07:34The problem is most likely the terminating condition for the loop in the remove() method.
QUESTION
I want to pass in some shape or form a dictionary/map/object into my clap app. I can preprocess the dict to turn it into some csv or whatever. My problem is that I cannot find in clap docs which characters are valid for the argument values and how to escape them. Is this unrelated to clap and instead shell specific?
Can I pass something like
myApp --dicty="a=1,b=3,qwe=yxc"
?
...ANSWER
Answered 2021-Feb-16 at 10:56Is this unrelated to clap and instead shell specific?
Mostly, yes. clap is going to get whatever arguments the shell has determined and will parse that.
However clap has built-in support for value sets, from the readme:
- Supports multiple values (i.e.
-o -oor-o)- Supports delimited values (i.e.
-o=val1,val2,val3, can also change the delimiter)
If that's not sufficient, then you'll have to define dicty as a String, you will receive the string a=1,b=3,qwe=yxc (I don't think you'll receive the quotes) then you'll have to parse that yourself, either by hand (regex/split/...) or with something more advanced (e.g. the csv crate though that's likely overkill).
That seems like a somewhat odd option value though.
FWIW structopt (which builds upon clap to provide a more declarative UI, and should be part of Clap 3) doesn't exactly have support for that sort of things but can be coerced into it relatively easily: https://github.com/TeXitoi/structopt/blob/master/examples/keyvalue.rs
With some modifications would allow something like

How to align at the bottom a flex-row inside a card? I currently have two cards aligned side by side but when one of the texts is smaller than the other the divs that contain "(100)(100)" lose their alignment.
I'm aware of questions likes this one but I have tried their solutions and nothing worked.
...ANSWER
Answered 2021-Feb-07 at 13:45If you add d-flex flex-column in card-body div and mt-auto in bottom div, will solve your problem.

QUESTION
I'm using clap to parse arguments. I want to use the single dash (-) and more than one character in the argument, like -Fmin 1. Adding long("Fmin") gives me that but with two dashes (--).
I'm aware that using a single dash and single character together is the norm. But is it possible to have clap use more than a single character when using the short() form? Or override the long-form so it defaults to a single dash?
...ANSWER

Judging by this issue, single-hyphen long options are not yet supported by clap.
