Add an EvalScript method to FsiEvaluationSession

[forki]

I just read http://fsharp.github.io/FSharp.Compiler.Service/interactive.html and saw fsiSession.EvalExpression(text) allows to evaluate an expression.
For fsprojects/FAKE#41 I would need an EvalScript method.

Is this possible?

EvalInteraction should do the trick, I think.

Im sure Ive used it for loading a script before.

You could always add an augmenter in Fake to read the file into a string.

I would like the opposite, a way of sending a string to fsi, rather than passing a script file. (Given that fsi is made a few orders of magnitude faster starting first)

Does an overload or additional method exist that takes a Stream? That's a lcm approach that would also work for hosting this on a web server and directly passing the request body to the evaluator.

The original inputs were stream based.

OK thanks will look into EvalInteraction and probably add some notes to the docs if it works.

Do you have a link? Do get it wortking. Always getting evaluation errors

[ghost]

@forki can you give more details of the errors you are getting. Using

EvalInteraction("""#load "script.fsx" """) 

should work I think.

[forki]

mhm. I tried to load the script file into string and evaluate the string. This #load trick sounds better. Actually it sounds useful enough to be extracted into own method.

Please send a PR to add that?

[forki]

if I succeed I will send a PR

Seems to work. I smell FAKE 3.0 in the air.

👍 I'm giddy with delight to see this. Correct me if I'm wrong, but shouldn't this allow for dynamic dependencies, similar to what @t0yv0 describes in https://github.com/Intellifactory/fshake?

[forki]

Actually I just want to run FSI in the same thread to get better debugging of build scripts. But I'm not sure this will work

[forki]

ok this is the first time a FAKE build stopped the debugger. yaaaaay

any ideas why it is one line to far? Maybe the #load directive?

[forki]

it's reproducable at different positions

[ghost]

@forki any update on this? Is there an FCS issue here?
