TYPO3 Core

thanks for this report.

In line 71 the operator =< highlighted wrong (two colored)

already fixed in my dev-version.
i will prepare a patch soon, so this should be fixed in the next release

Patch attached

Summery:
Problem I:
After an operator (= > and <) the parser expected a "value". If the operator is the last char in a line (e.g. when deleting a property with >), the parser detects complete next line as value.

Test I:
    open the t3editor and write the following code:
     temp.foo = value
     temp.foo >
     temp.bar = another value

Line 1 should be correct. 
    Type no space after > in line 2. 
    If the attached patch is not applied, the line 3 would get red colored
    If patch is applied, line 3 is colored correct.
    See Screenshot attached to the issue in the  bugtracker

Problem II:
    Reference operator "=<" is not detected as a operator correctly, but gets "two-colored". This is, because the "<" is detected as a value of the "=" operator.

Test II:
    type:
     temp.foo =< temp.bar

Solution:
    Detect if operator is followed by a line break
    and detect if "=" is not followed by "<"
