class SyntaxSuggest::Capture::BeforeAfterKeywordEnds
Shows surrounding kw/end pairs
The purpose of showing these extra pairs is due to cases of ambiguity when only one visible line is matched.
For example:
1 class Dog 2 def bark 4 def eat 5 end 6 end
In this case either line 2 could be missing an ‘end` or line 4 was an extra line added by mistake (it happens).
When we detect the above problem it shows the issue as only being on line 2
2 def bark
Showing “neighbor” keyword pairs gives extra context:
2 def bark 4 def eat 5 end
Example:
lines = BeforeAfterKeywordEnds.new( block: block, code_lines: code_lines ).call()
