import JSONLibrary to red.xml error

[kenifanying]

I have install JSONLibrary via pip install -U robotframework-jsonlibrary and create a test project. After that, I try to include JSONLibrary's keywords into red.xml by autodiscovery mechanism, but I get non-accessible error.

Then, I try to import manually and get more error message as below :

Detail error message:

Hi

I reproduced your error, have you used right click menu on file/folder "Automatically discover and add libraries to red.xml"?

The workaround for now is:

1. remove JSONLibrary entry from red.xml (as it was not autodiscivered yet by RED)
   

2. go to test file where you have JSONLibrary import, such import should be underlined as unknown library

3. click on it, from right click menu select Quick Fix (shortcut CTRL+1)
   

4. JSONLib should be properly recognized and added to red.xml

We will have to look into issue, hopefully workaround does not impact much RED usage.

Alternatively, you can generate list of keywords from JSONLibrary in your shell and add it to red.xml as libspec file with command python -m robot.libdoc JSONLibrary <path_to_output_libdoc_xml> :

1. open shell/cmd: python -m robot.libdoc JSONLibrary c:\JSONLib.xml
2. open red.xml, from Referenced libraries tab select Add libspec file and use generated file

Yes,

I have try this solution, but it's not work for me, same error occured as "Automatically discover and add libraries to red.xml"

We will have to look into issue, hopefully workaround does not impact much RED usage.

Thank you, this solution temporarily solve my problem.

[KrzysztofJozefowicz]

Thanks for feedback. to be sure - you have removed JSONLibrary entry and saved red.xml,right?

I will reopen this case as there is a problem with autodiscovery of JSONlib still to be examined.

Yes， exactly

Sorry for my mistake.

In RED 0.8.11 generation of libdoc was moved to separate process outside of server process which fixes this issue. It can be controlled in preferences (see Preference for generating libdoc at http://nokia.github.io/RED/help/user_guide/working_with_RED/libs.html).
