Properties.load() skip the second line of InputStream in the following case. Is it a bug or normal behaviour of Java?

ANSWER

Answered 2021-Mar-01 at 13:00

According to the Properties file format

A property value can span several lines if each line is terminated by a backslash (‘\’) character.

You have a trailing space in the second version. So the line isn't continued. Note the whitespace rules, which are a bit confusing.

White space that appears between the property name and property value is ignored,

and

White space at the beginning of the line is also ignored.

So that means white space at the end of the line isn't explicitly ignored.

grammar does not separate '123 and ] though the rule is set for it

That is not true. The quote and 123 are separate tokens. As demonstrated/suggested in your previous ANTLR question: start by printing all the tokens to your console to see what tokens are being created. This should always be the first thing you do when trying to debug an ANTLR grammar. It will save you a lot of time and headache.

The fact [network-traffic:src_port = '123] is not parsed properly, is because the ](RBRACK) is being consumed by the alternative observationExpressionSimple:

Proptest: Strategy to generate vectors of vectors

Asked 2020-Sep-16 at 21:05

I want to generate DAGs with proptest. The algorithm that I pick would be this. I've written the plain algorithm below -- but I need help transforming this to a proptest strategy.

What would a strategy need to look like that did the same as the below code but without using a random number generator? (It goes without saying that random number generators are bad for property-based testing.)

Standard code without proptest strategy: (https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=2de4a757a96d123bf83b5157e0633d33)

Answered 2020-Sep-16 at 18:42

One way to go about this, is to replace each rng.gen_range() call with a strategy. Nested strategies must then be connected with prop_flat_map.

In the below code, I replaced my pattern let length = rng.gen_range(0, N); for i in 1..length { .. }, with a new function vec_from_length(length: usize), which returns a Strategy.

Seems like, for your working sample (with PropName) you define the property name in property path, but for printers you define a property value lst_PrinterToGridBindings[i].extPrinterName. Have a look at Binding.Path property. You also should specify the Source for binding

ANSWER

Answered 2020-Jan-10 at 16:05

This is the expected behaviour. For maven projects, while running, project is build and is kept in target folder always. you can also change this folder by some configuration. From this target folder, your application runs and thus your path shown in classloader.getResource() method. If you are building a jar , then your resources will be inside the jar and is always available. So classloader.getResource() will be working fine always.

Does Google script properties change types?

Asked 2019-Nov-14 at 10:46

I am trying to store a list of strings as a global variable and be able to append to it in different scripts. According to this this answer one way of achieving the same result is with a PropertyService and Properties. I have defined a global document properties variable and can get and set the properties in it. However, if I set a key to hold an array, when I next get the properties, it does not act like an array.
