Not with threading. Thus, OLAP and any other execution engine that uses 
threads will get inconsistent results.

Looking at the exp4j source, I think an `Expression`  can be reused. If so, 
this could be moved up into the constructor to save the repeated initialization 
cost.

Github user dkuppitz commented on the issue:

https://github.com/apache/tinkerpop/pull/729
  
You can add a static compiled regex pattern:

```
private static final Pattern EQUATION_PATTERN = 
Pattern.compile("\\b(?!abs|acos|asin|atan|cbrt|ceil|cos|cosh|exp|floor|log|log10|log2|sin|sinh|sqrt|tan|tanh|signum)(_|([A-Za-z][A-Za-z0-9]*))\\b");
```

...then `getVariables()` can be as simple as:

```
protected static final Set getVariables(final String equation) {
final Matcher matcher = EQUATION_PATTERN.matcher(equation);
final Set variables = new LinkedHashSet<>();
while (matcher.find()) {
variables.add(matcher.group());
}
return variables;
}
```

And perhaps to increase the readability and maintainability, we should do 
something like this:

```
private static final String[] FUNCTIONS = new String[] {
"abs", "acos", "asin", "atan",
"cbrt", "ceil", "cos", "cosh",
"exp",
"floor",
"log", "log10", "log2",
"signum", "sin", "sinh", "sqrt",
"tan", "tanh"
};

private static final Pattern EQUATION_PATTERN = Pattern.compile("\\b(?!" +
String.join("|", FUNCTIONS) + ")(_|([A-Za-z][A-Za-z0-9]*))\\b");
```

Sure. I had hacked together a basic implementation, minus tests and a few
key methods, before I felt compelled to leave for work. Maybe I can put up
the code tonight or tomorrow morning.

TINKERPOP-1632: Create a set of default functions

https://issues.apache.org/jira/browse/TINKERPOP-1632

This is an implementation of lambda-less math capabilities in Gremlin 
leveraging the String-based calculator model proposed by @twilmes. This model 
deviates from Gremlin's standard function composition and nesting model to 
provide a easy to read "math processor" that leverages Gremlin scopes for data 
access (e.g. path data, map keys, and side-effects). The feature is 
encapsulated in `MathStep` which implements `PathProcessor` and `Scoping`. 
Furthermore, `by()`-modulation is supported. `by()`-modulators are applied in 
the order in which the variable is first used in the equation. Thus:

```
g.V().as("a").out("knows").by("b").
  math("b + a").
by(out().count()).
by("age")
```

In the above: `a` -> `age` and `b` -> `out().count()`. More complex 
examples are provided below:

```
gremlin> g = TinkerFactory.createModern().traversal()
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin> g.V().as('a').out('knows').as('b').math('a + b').by('age')
==>56.0
==>61.0
gremlin> g.V().as('a').out('created').as('b').
..1>   math('b + a').
..2> by(both().count().math('_ + 100')).
..3> by('age')
==>132.0
==>133.0
==>135.0
==>138.0
gremlin> g.withSideEffect('x',10).V().values('age').math('_ / x')
==>2.9

commit 6f1a1f7028f285c6e45b7e7596320710b91114c5
Author: Marko A. Rodriguez 
Date:   2017-10-03T23:37:10Z

first non-tested implementation of math()-step. It uses the @twilmes model 
which parses a String representation of the expression.

Author: Marko A. Rodriguez 
Date:   2017-10-04T16:27:48Z

I wrote a small parser that is able to extract variables from an exp4j 
equation. So far, it is pretty durable. This is a much cleaner way of 
determining variables than via label, side-effect, and map analysis. However, 
this means that the by()-modulations are with respects to the order in which 
the variables are contained in the equation.

Date:   2017-10-04T16:42:06Z

added MathTest to test math() using step labels, side-effects, and implicit 
current -- and with various uses of by()-modulation. This is a really cool step.

added MathStepTest to test hashCode() and the custom variable finder. Found 
a couple of problems in my parser and I fixed them. Forgot to make MathStep a 
PathProcessor so that OLAP is smart about data access. Both OLTP and OLAP tests 
pass.

That's probably a worthwhile exercise. FYI, I have gotten a start on a
minimal Redis-based impl -- not so much as a template as an example of what
can be done in a few lines of code.

Thanks, ill try to take a stab at this and write a hello world i can use as
a template. If i do such a hello world would it be useful for you guys.

Re: Im starting a new project, but tinkerpop3 seems incapable, considering forking tinkerpop2

2017-10-04 Thread Marko Rodriguez

Hello,

You have the following tasks:

1. Implement Graph, Vertex, Edge, VertexProperty, Property interfaces.
2. Implement Transactional interface (optional).
3. Write as many strategies as you want to take advantage of 
provider-specific capabilities.
- TinkerGraph itself has 2:

https://github.com/apache/tinkerpop/tree/master/tinkergraph-gremlin/src/main/java/org/apache/tinkerpop/gremlin/tinkergraph/process/traversal/strategy/optimization
 


If you want a minimal “hello world,” then please look at TinkerGraph and 
Neo4jGraph in our repository. Those are both “reference implementations.”

https://github.com/apache/tinkerpop/tree/master/tinkergraph-gremlin 

https://github.com/apache/tinkerpop/tree/master/neo4j-gremlin 


Good luck,
Marko.

@BrynCooke i've been looking at this on and off since it was submitted and

still get to release the {{evaluationFuture}} for GC with this added blob of

> Ran into this message when adding a .profile() step, even though Gremlin

> {code}
> gremlin> 
> g.V().has("Question","questionType","yes/no").in("has_question").order().by(inE("reviewed").values("rating").mean()).profile()
> The provided step contains a lambda comparator: 
> OrderGlobalStep([[[VertexStep(IN,[reviewed],edge), 
> PropertiesStep([rating],value), MeanGlobalStep@[~gremlin.profile]], incr]])
> Type ':help' or ':h' for help.
> Display stack trace? [yN]
> {code}
