QUESTION
I am working on a project with jline version3 in java but in completion, I need to have "else if" but it puts \ to escape space as an escape character and I don't have any escape character also I tried null
instead of a char[]
but it crashes with null pointer exception
also, I checked https://github.com/jline/jline3/issues/173
Error is:
...ANSWER
Answered 2020-Sep-08 at 11:31I assume that you are using JLine builtin completer StringsCompleter
and DefaultParser
.
If you have completion candidate that have space character(s) then either
- space chars are escaped if
defaultParser.escapeChars != null
or - completion candidate will be quoted if
defaultParser.escapeChars == null
.
That is how StringsCompleter
is supposed to work.
See StringsCompleterTest.java methods: escapeCharsNull()
and escapeChars()
.
NPE is fixed in commit 68a9c1f. You should use JLine version 3.10 or greater.
QUESTION
The problem I'm having is the try catch part of my java program. When the user inputs a number between 1-4 it works. But when the user enters a number that isn't it doesn't catch the error and print out the error text. I put the whole program in if that helps... Any help would be appreciated.
...ANSWER
Answered 2018-Mar-22 at 22:28In your program the NumberFormatException
will catch input that is not a number.
When you enter a number that isn't 1-4
there is no exception thrown so the program just goes back to the beginning of the loop.
QUESTION
I'm trying to write a simple, arrow-driven options menu for a C#.NET console application. Given a dictionary of options to a character return type, users would choose an option with their up/down keys, and select it with Enter.
Problem is, the switch statement breaks out of the program completely after the first run. I've tried placing breakpoints and figuring it out, to no avail-
EDIT: Decided to separate out this code from some of the async code that was also written into the class. For whatever reason, that lets it work as intended, so.. now I need to figure out why async would be messing with this, there's no await needed for a sync operation like this..
Code:
...ANSWER
Answered 2017-Dec-27 at 10:51There is no problem with your code except one, As I have tested it in my console app the last option never can be selected because of your if
condition in ArrowDown
so it would be changed like :
