Too many arguments to Wait for condition in Robot Framework?

I have the following line in Robot Framework

Wait for condition  'Get element attribute  id:something  attribute=something_else'  ==  'abc'

I think this is pretty self explanatory: I want to wait until Get element attribute returns abc.

However, this returns an error message

Wait for condition expected 1 to 3 arguments, got 5.

On an abstract level, this error message is pretty clear but I don't understand how it applies here. The five arguments it refers to are arguments not to Wait for condition but to Get element attribute. I want to send two arguments to Wait for condition that should be equal, the return value from Get element attribute and the string abc.

How do I write this?

In the other answer it was rightfully pointed out the Wait For Condition keyword is just for js code being ran in the browser. Here's how to do what you want with the builtin keyword Wait Until Keyword Succeeds and SeleniumLibrary's Element Attribute Value Should Be:

Wait Until Keyword Succeeds    retry=1 minute    retry_interval=5 seconds    Element Attribute Value Should Be    id:something  attribute=something_else    expected=abc

The Element Attribute Value Should Be is new in Selenium Library v3.2, if you don't have this version yet, here's a sample implementation:

Attribute Value Should Be
    [Documentation]    Fails if the element's attribute is not the expected one
    [Arguments]    ${locator}    ${attribute}    ${expected}

    ${value}=    Get Element Attribute    ${locator}    ${attribute}
    Run Keyword If    """${value}""" != """${expected}"""
    ...     Fail    The attribute's value is different from the expected: ${value} != ${expected}

This is not how wait for condition works. You can't give it a keyword. You must give it a javascript expression.

From the documentation:

The condition can be arbitrary JavaScript expression but it must return a value to be evaluated. See Execute JavaScript for information about accessing content on pages.
