kandi X-RAY | writ Summary
Writ is a flexible option parser with thorough test coverage. It's meant to be simple and "just work". Applications using writ look and behave similar to common GNU command-line applications, making them comfortable for end-users. Writ implements option decoding with GNU getopt_long conventions. All long and short-form option variations are supported: --with-x, --name Sam, --day=Friday, -i FILE, -vvv, etc. Help output generation is supported using text/template. The default template can be overriden with a custom template.

QUESTION
I can't see my image once I've saved it.
Image to Base64 method in my Android project
...ANSWER
Answered 2021-Jun-13 at 00:17EDIT: BETTER WAY
INSTEAD OF EDITING THE STRING IN THE SERVER WE SHOULD ENCODE IN ANDROID THIS WAY
Base64.encodeToString(bytes, Base64.NO_WRAP);
AND GET IT IN THE SERVER THE USUAL WAY WITHOUT EDITING THE STRING
java.util.Base64.getMimeDecoder().decode(yourByteArray);
PREVIOUS WAY:
I just had to edit the String that i was getting in the server by removing the quotes surrounding it with img.substring(1, img.length() - 1)
and the \n with img.replace("\\n", "")
.
The result code in the server is like this:
QUESTION
The menu expands and contracts when I click on a button. The button toggles the "active" class when I click it as expected with only the code required for that action. However, when I add the code to make the the menu contract when clicking elsewhere on the page, it only contracts when clicking everything EXCEPT for the button. The button is no longer clickable and the menu remains expanded until I click on a link or on the body of the page.
EDIT: As I was typing this out on a jsfiddle, I got an error on that console that I don't see in my dev tools: Uncaught ReferenceError: jQuery is not defined The reason why I am not using the "$"symbol that I see everyone using, and I am writting out "jQuery" in front of everything is because that's the only way I could make DIVI (the wordpress builder) compile the code
...ANSWER
Answered 2021-Jun-10 at 15:57The toggles in each of your handlers are competing with each other events from one will bubble up to the other causing them to both fire simultaneously, toggling the nav right back to its initial state. Here I changed the 'body' handler to only remove the 'active' classes; and added a stopPropagation to the nav click handler so it doesn't bubble up and also trigger the body handler.
(I also added a bit of CSS to cause body
to fill the viewport.)
QUESTION
I´m trying to rename two types of variables in R using tidyverse/dplyr. The first type "var_a_year", I want to rename it as "sample_year". The second type of variable "var_b_7", I want to rename it as "index_year".
The second variable, "var_b" starts on the number 7 for the first year "2004". And increases by 2 for each year. So for year 2005, the second type variable is called "var_b_9" as shown.
I would like to use a loop so I can make this faster instead of writting a line for each year.
Many thanks in advance!

QUESTION
I have a folder of images as such
...ANSWER
Answered 2021-Jun-08 at 13:47Using datasets.ImageFolder
will make PyTorch treat each "band" image independently and treat the folder names (e.g., img1
, img2
...) as "class labels".
In order to load 5 image files as different bands/channels of the same image, you'll need to write your own custom Dataset
.
This custom Dataset
may look something like this:

I am getting this error when trying to predict the image from loading it from streamlit file_uploader. the process is working fine when I try directly loading the image in ide. but the problem is arising with streamlit file_uploader. i can't figure in which file type the streamlit is uploading the file. Please help me with how I can upload a custom image and predict it with the Keras model.
it is showing this error.

Answered 2021-Jun-04 at 10:06Since you already have the image in the buffer you can try this.
QUESTION
I am hosting an angular application in azure web app. I want my application should be only accessible on chrome browser. If someone access the site from other browser then user should redirect to browser restriction page. So to achieve this is there any policy available that can be added to web app, instead of writting the code to detect the browser and then redirect?
- Rajesh
ANSWER
Answered 2021-Jun-04 at 01:09Azure web app does not have the functionality to restrict access to the browser as you described.
Reason
Azure app service (Windows & Linux) is essentially a webserver running in a sandbox, which is no different from real IIS or Nginx and Apache.
WebServer provides program deployment and access functions, and only receives
HttpRequest
. As for the information contained inHttpRequest
, azure app service does not provideanalysis
.For example, adding
User-Agent: Chrome
is the specific information contained in HttpRequest. This means that we can only determine the source by parsing the HttpRequest through the code.
QUESTION
I am looking for an android emulator (nox, BlueStacks, etc.) to work while I'm writting android apps to speed up the testing.
I found lots of tutorials showing how to connect the emulator but my problem is that none of my apps created with Delphi (even just a button and a showmessage) are able to work with this emulators (they are supposed to have libhoudini installed) the app starts and closes.
Is anyone working with an emulator and the binaries created with Delphi work? I just tried all the new emulators, and I could not download the old ones (the ones I see un the tutorials)
Any hint is appreciated
Regards
...ANSWER
Answered 2021-Jun-03 at 20:04Finally I managed to have a decent environment with GenyMotion + libHoudini + tcpip debug.
First, install Genymotion https://www.genymotion.com/
Then, update the libhoudini at https://github.com/m9rco/Genymotion_ARM_Translation
Finally, I could do app test through tciip which was not a problem because Genymotion shows virtual device IP.
I cannot debug, but I can launch the application pretty fast and with logs I am able to debug...
QUESTION
First of all, thank you for your help.
I'm currently writting a blog in vue.js with vuejs-cli and I'm stuck on a problem about the architecture of my blog.
What I want to do:
I want my vue.js app to fetch an article (which is a whole webpage with .html,.js,.css and pictures) in the subfolder of the "Articles" folder and then display it in a vue in two ways:
- like a preview (an image from the article and the article's title)
- by diplaying the full article
So I want the file tree to look like this:
...ANSWER
Answered 2021-Jun-02 at 07:26I finally made it works !
This is how I did it:
- I put my
Article
folder in thepublic
folder of vue-cli - Created a nodejs programme to make/update a database of all articles in the
article
folder every 10 minutes, sorting them by date of creation (I will make a cron job with cron later) - Made this nodejs programm to answer to some
GET
query:- when I want a preview, the programm send a "preview" of the article (it takes the title, the description and the first image of the html file of the
article
and send it in a html format) - when I want a url, the programm send the link of the html page inside the
public
folder (see how to do it here)
- when I want a preview, the programm send a "preview" of the article (it takes the title, the description and the first image of the html file of the
- So on my vuejs app, the view fetch a preview to the nodejs backend with the fetch api and show it. Then, when the user click on the preview, my vue show a
ifram
of the webpage's article at the specified url fetched.
Tips: Be aware that npm build
will erase the Article
's folder if it's only present in the dist folder. To avoid it, change the script of package.json
to add the --no-clean
argument to the build command
I don't know if it's a good and efficient way of doing it, but it works well and it's very easely customisable. So for the moment, I'll do it like that way :)
QUESTION
Here is my issue : I a have a class of objects defined by a certain amount of attributes and methodes among which :
- A "type" attribute that resumes to text or image
- A drawObject methode that will either draw (canvas drawImage function) the object on a canvas if it is an image or "write" the object on the same canvas if it is a text (canvas fillText function).
On the canvas a I can draw/writ any amount of those objects that are stored in an array.
My problem is I am trying to have those objects drawn in a given order so that the overlaping is consistent to the order of the objects in the array.
to do so, I am parsing all objects in the array in the following manner :
...ANSWER
Answered 2021-May-30 at 21:40In case anybody needs the answer the issue was fixed in my case by using Bergi's advice and making the drawObject return a Promise.
QUESTION
I have a textinput that accept any numbers that are dividable by 500 examples 1000, 1500, 2000, 2500 3000, etc. if the user write 12263 it should display 12000 if the user write 12789 it should be 12500
I have this code, but it doesnt work at all, at some numbers work fine, but with other it just go to the max number
vPayrollBureauMaxOffer: is the max number that can be accepted i get this value from an api vPayrollAmount: is the amount the user writ in the textinput 3000 is the min value accepted if the user write a number less than 3000 it should change to 3000
as an example let say that the max number is 250000, when i write 50000 it goes to 250000 if I write 4000 it also goes to 250000, i have seen that this only happens with numbers that are less than 100000 i dont know what happens
this is my code
...ANSWER
Answered 2021-May-27 at 16:58This sounds like you have vPayrollBureauMaxOffer = "250000";
when it needs to be vPayrollBureauMaxOffer = 250000;
and it is doing string comparison, where "50000" > "250000"
, but 50000 < 250000
.
