v0.3.0

Features

• Add support to variable binding inside cypher macro. Now external variables (including maps) can be resolved within cypher macro:

person = %{name: "bob", age: 12}
cypher do
  match(node([:Person], %{name: person.name, age: person.age}))
end

• Expand support to other comparison operators inside WHERE statements. Now, besides the common elixir comparison operators (!=, <, >, <=, >=), the equality operator was replaced by the elixir one (==)
• Added support to SET statements within queries:

# SET usage example:
cypher do
  match(node(:p, [:Person], %{name: "Andy"}))
  set(p.name = "Bob")
  return(p.name)
end
"MATCH (p:Person {name:\"Andy\"}) SET p.name = \"Bob\" RETURN p.name"

• Added support to variable aliasing:

# Cypher aliasing example
cypher do
  match(node(:n))
  pipe_with({:n, as: :p})
end
# "MATCH (n) WITH n AS p" = query

Check full documentation to see the command's usage.

Improvements

• Ensure support for elixir 1.8.2, 1.9.4 and 1.10.0
• Add integration specs into CI pipelines - this'll ensure correctness in excypher generated queries

Fixes

• Replaced = equality operator with elixir's one (==)
