kandi X-RAY | rever Summary

rever is a Rust library typically used in Utilities, Interpreter applications. rever has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Assertions should allow a statement running in reverse to determine what value a variable should have at the end of its life, which branch to take for conditionals, or what the starting condition is in loops. In conditionals, they should reflect what changes the first code block made to the variables. If the variables being tested aren’t changed in either branch of code, then you can safely have the assertion be the same as the test. If variables in the test are being changed, the assertion cannot be the same as the test, and must reliably choose which branch should execute when going in reverse. In loops, the assertion can be the end value of the iterating variable, or a predicate that depends on any variable whose value depends on the loop.

Vue JS - How to save the selected value of a radio button to local storage

Asked 2021-May-18 at 21:39

I have two radio buttons that are connected to each other, they accept a boolean value, either true or false, I need to do so that when one of these values is selected, the value is stored in the local storage, for example, it chooses true, the true value is stored in the local storage if then chose false the true value was deleted and the false value was kept and vice versa I think the problem is clear

You can also look at my code in codesandbox

You could add a watcher to save the value of websiteAccept to local storage whenever the value changes.

JSReact, Deleting any dynamically added form content other than last item wipes the form

Asked 2021-May-17 at 03:09

I'm building a form with dynamically added fields and am working on the ability to delete fields if a user changes their mind about one. When deleting the last item added it works as expected, but if I have, for example, 3 dynamically added fields and delete the 2nd one, it will momentarily work and then wipe the whole form clean. Does anyone know why this might be happening?

Codesandbox link here, but I'm including (what I think is) all the relevant code below:

From "form.js":

You must call e.preventDefault() at the top of handleDeleteCredit. The problem was default form behavior and the result was the entire page reloading fresh.

QUESTION

Vue3 reactivity lost when using async operation during object creation

Asked 2021-May-09 at 03:18

I'm working with some objects (classes) in my TS codebase which perform async operations right after their creation. While everything is working perfectly fine with Vue 2.x (code sample), reactivity breaks with Vue3 (sample) without any errors. The examples are written in JS for the sake of simplicity, but behave the same as my real project in TS.

I visited the code sample you posted and it it is working, I observed this:

You have a vue component that instantiates an object on its create hook.
The instantiated object has an internal state
You use that state in the vue component to render something.

it looks something like this:

How do I fix sorting issue in Cobol program?

Asked 2021-Apr-13 at 07:49

I have a program that is suppose to sort an input file (seq) and then output an RPT file.

This program code should be correct, the problem should only be in the sorting of this program.

PROBLEM: The program successfully sorts the data correctly, my problem is that I can not get the sort file to continue after being sorted to be formatted and do calculations.

ANSWER

ARE-THERE-MORE-RECORDS = 'NO' is still true from its use in the input procedure. At the beginning of the output procedure, insert MOVE 'YES' TO ARE-THERE-MORE-RECORDS. You also need to replace the READ BASEBALL-FILE-IN with RETURN SORT-FILE, add some fields to SORT-RECORD, and use those fields for the report.

Why do you have BASEBALL-FILE-UNSORTED-IN? It doesn't have any of the fields you need to move to SORT-RECORD.

If you want to use BASEBALL-FILE-UNSORTED-IN, then don't use an input procedure. Instead change the SORT statement from INPUT PROCEDURE 120-SORT-INPUT-PROCEDURE to USING BASEBALL-FILE-UNSORTED-IN. Do not OPEN or CLOSE the file. That will be done by the runtime. Remove the 120- and 130- paragraphs.

Comment everything associated with BASEBALL-FILE-IN, except 01 BASEBALL-RECORD-IN and its data items. That effectively allows the BASEBALL-RECORD-IN data definition to be used as a replacement for SORT-RECORD. That reduces the number of changes that are needed.

ANSWER

Answered 2021-Apr-12 at 17:57

SORT is not being used correctly. The report is being printed in 120-SORT-INPUT-PROCEDURE using the fields from BASEBALL-RECORD-IN. It should be printed in 130-SORT-OUTPUT-PROCEDURE using the fields from SORT-RECORD.

Furthermore, no records are sorted because there is no RELEASE statement in the input procedure. To access records after the sort, a RETURN statement is used in the same manner as a READ statement for a sequential file.

The input procedure should be used to move the data from selected records to the sort record, after which the record is released to sort.

The output procedure may then used to produce a report from the sorted data by returning and printing each record until the there are no more sorted records.
