Quasiquoter parse error after setup

[Cody Goodman]

I followed this instructions:

$ git clone http://github.com/tweag/HaskellR
$ cd HaskellR
$ stack --docker build
$ stack --docker exec ihaskell install

And get started in your browser:
$ stack --docker exec ipython notebook

Then I opened 127.0.0.1:8888, and got the following error:

[r| require("ggplot2") |]

Parse error (line 1, column 23): parse error on input ‘]’

I'm using:

~ $ stack --version
Version 0.1.4.1 (UNKNOWN commits) X86_64
~ $ uname -r
3.16.0-38-generic
~ $ cat /etc/issue
Ubuntu 15.04 \n \l

Hi Cody,

have a look at the IHaskell/HaskellR tutorial found here:
https://github.com/tweag/HaskellR/blob/master/IHaskell/examples/tutorial-ihaskell-inline-r.ipynb.

You'll notice that the first line of code is basically turning on the
quasiquotation extension. In H, this is turned on by default, but we
haven't found a way to get it turned on by default in IHaskell as well
yet. Maybe Andrew Gibiansky has an idea.

Best,

I think the best solution would be to add:

Visit http://localhost:8888/notebooks/IHaskell/examples/tutorial-ihaskell-inline-r.ipynb in your browser for an interactive tutorial.

right after:

And get started in your browser:
$ stack --docker exec ipython notebook

and above the image of that page. Otherwise the user will have to do some exploring around and might assume setup didn't work like I did.

Hi Cody,

good idea! This should be fixed now in the latest build instructions
on the website.
