QUESTION
I am trying to add a Mandatory field option for the argument in my dart script. I am using addOption() as visible in the code below. and to run the code in the terminal.
...ANSWER
Answered 2021-May-04 at 17:03Note that there is nothing special about the -h
/--help
option itself. It is a boolean flag like any other. Consequently, since you've made -n
/--name
mandatory, it is exactly that: it is always required, even if you're just trying to print usage text.
The way that -h
/--help
is handled provides its own clue how you can make an option conditionally required: check ArgResults.wasParsed()
and explicitly fail if it's not provided:
QUESTION
EDIT:
As per the comment on the answer below: removing "type": "module" from package.json
, which as I understand it is what makes Node understand 'import' and 'export' statements, and reverting everything to 'require' and 'module.exports' solved the issue.
Is there a way to keep 'import' and 'export' and still make Mocha work?
I have a very simple Node file that I'm trying to test with Mocha/Chai. The actual code is trivial, this is just to learn a bit about Mocha and how to use it. But when I run the Mocha test, I get the error ERROR: ReferenceError: require is not defined
`
I did some googling for people experiencing the same problem but the examples that I came up with were when they were running the test in the browser (see, for example, Mocha, "require is not defined" when test in browser).
The file I want to test, index.js

QUESTION
I'm struggling to pull elements from an SQLite table in Android Studio and display the elements in a ListView. The area where I believe the error to be in is when I set the List adapter to my array.
First, here is the code in my SQHelper class. It retrieves the list of items to be displayed.

Answered 2020-Oct-16 at 21:21Posting this answer for future visitors. The issue lied in my Course class. I changed it to this, and it worked. The variables were originally declared static, which was the issue.
QUESTION
I wrote a standalone script deployed as a web application. The point of the script is that by clicking on a button a Google Sheet file is copied to a specific directory, then I want the new file to open. My code is blocking to open the new file. Parts 1 and 2 in codeTest.gs work perfectly (roughly from the value associated with the clicked button, the script will look in a Google Sheet file for the name to give to the form as well as the location where it must be copied).
In my code you will notice that I am talking about a form, but it is indeed a Google Sheet file (in practice the Google Sheet file is a document to be filled in which is similar to a form).

I am trying to find out how to easily index the row number based on a search of the excel document.

QUESTION
I am looking for a little nudge on where to look for the answer of this. I have finally gotten my code to where it will return the row index of a user search. Now my problem is I have the row index, I now need to be able to take that row # returned from the user search and start spitting out each column data from that row, how can I print the indexed row (Searched_Service_Row_Location) from each column? May be simple but I have spent a good amount of this Sunday looking for how to do so, any tips is much appreciated. Tried to go down the .iloc road but couldn't get what I wanted.
...ANSWER
Answered 2020-Aug-17 at 17:05Hoping this will help someone later on, was able to grab what I needed. What was needed was the following 2 lines below. Using iloc I was able to specify what row/column I wanted to print, and I already had my row index stored under "Searched_Service_Row_Location", I simply added the below to print that row and column cell value. Probably not the cleanest, but at least for my problem this got me what I needed.
QUESTION
I am looking to update a button in my code by running a function later in the code that references a previous function, then update that said button with new text. When I run this code, it states that Source1 is not defined when the okay 3 function runs the if statement. New to coding and looking for tips. Thanks
...ANSWER
Answered 2020-Aug-05 at 22:07The problem is that your Source1
is a local variable and hence it is available only to the function that you defined it on, that is, Standard_flow()
. To make this global and fix the error, just try saying this:

I'm working on a project in which I have to perform some byte operations using python and I'd like to understand some basic principals before I go on with it.
...ANSWER
Answered 2020-Mar-21 at 23:03Because bytes
objects and str
objects are two different things. The former represents a sequence of bytes, the latter represents a sequence of unicode code points. There's a huge difference between the byte 172 and the unicode code point 172.
In particular, the byte 172 doesn't encode anything in particular in unicode. On the other hand, unicode code point 172 refers to the following character:
