    My Keyword    specifiedText\=withEqual    opt=value

    My Keyword    text=options = value    opt=value

Thanks, the issue seems to be that the language server is not considering \ as an escape char for = so that it doesn't consider it a keyword argument but rather a regular positional argument.

Both the code-analysis as well as the semantic highlighting seem to be confused.

I'll make sure it's fixed for the next release.

I'm not sure that it is only related to \ character, though there is one more case when the language server complains about missing mandatory argument.
NOTE: There is no \ symbol, but it is still valid RF code

*** Settings ***
Force Tags    vscode
*** Variables ***

*** Test Cases ***
My Test Case
    My Keyword    options = value
    My Keyword    options = value    option_value

*** Keywords ***
My Keyword
    [Arguments]    ${text}    ${options}=${EMPTY}
    No Operation

And for the second keyword call the server incorrectly defines named argument syntax

That's actually a different case -- and quite surprising to me actually because usually RF should normalize things to match a variable, so, I thought that options = value would be exactly the same as options= value, but it isn't...

Thanks for finding that ;)
