[CR] JSONtext

[Vortexhunter]

Thanks for that! It's what the machine is replying with, so I am stuck doing a string conversion after... 😒

Hello,

I used JSONtext library in my old project and now I tried to brush this project and install this library through VIPM to Labview 2023 again ... There appeared an error concerning dependencies "VIPM couldn't download the package JDP Science Common Utilities v1.4.1.18 from the remote server ... Could you please check availability of this package?

Thanks

Jiri

Hi

The Reformat.vi function has a boolean input "Format empty string as null".

This input seems to be fully ignored as it happily continues to output "some_param":"" (empty string) instead of "some_param":null

 

 

[LogMAN]

In the context of this VI, "empty string" refers to the JSON terminal. If you don't provide any input, it will return null. Otherwise, it returns an error.

I will change the terminal name to "Format empty input as null" to prevent reading it as referring to JSON Strings in the input rather than the entire LabVIEW string.   And I'l try and give a better description:

[X___]

When passing a "no error" error cluster to the "To JSON Text.vim" VI of the JSONtext toolkit, the output string is empty.

This is not the expected behavior.

I would expect:

  status = false
  code = 0
  source =

Tested with v1.9.1.125 in LV 2021 SP1 on Windows

[LogMAN]

This works as expected in version 1.7.0.118

Tested with LV2019 SP1 (32-bit)

{"status":false,"code":0,"source":""}

[drjdpowell]

Can you give an example VI showing the problem.  It seems to work in teh current source code.

[X___]

My apologies, I must have had a brain fart when I looked into that (I suspect isolating the vim from the VI I was using it and not connecting a "no error" constant to the input)?

Things work as they should upon checking again.

Hi, I am using jsontext library in a project which I have been asked to localize to Chinese but get "??" out when using from jsontext.

Is there a way to do this that I am missing, or am I doing something fundamentally wrong. 

The dev PC in windows has all the localization / regions set to Chinese.
 

Thank you

JSON is always in UTF-8, and JSONtext will try and convert to your computer's character set automatically, so I don't think you need any of that stuff that has "UTF8".  Try simply using the single function to convert to a 2D array of strings.

However, by sure you are actually passing true JSON, with UTF8 encoding, not whatever your computer is using.

Thank you,

The issue was I was binding the string to a sqlite db as a "utf-8 string" then reading it as a "string", which is why it was causing it to fail.

I have made the execute sql vi read it as a single utf-8 which fixed it.
