Purescript build for docker
# usage
Note: You may need to run docker comands as a superuser (sudo) depending on how it's configured on your system.
Pull the version you want to use:
```
$ docker pull gyeh/purescript:0.9.1
```
Check to see that your image was created:
```
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
gyeh/purescript 0.9.1 b09608732ec8 0 minutes ago 831.9 MB
```
Try the Purescript REPL (you need to run it in interactive mode with a pseudo-teletype):
```
$ docker run --rm -it b09608732ec8

```
To start doing real work with it, you need to mount a volume to your docker container when you run it.
Clone the [Purescript By Example](https://leanpub.com/purescript/read) code as an initial example:
```
$ git clone https://github.com/paf31/purescript-book
Cloning into 'purescript-book'...
Checking connectivity... done.
```
Then mount the volume using the absolute path of the cloned repo to the `/home/pureuser/src` folder in the container:
```
$ docker run --rm -itv ~/git/purescript/tmp/purescript-book/:/home/pureuser/src b09608732ec8 bash
pureuser@1ddb0b0ed568:~$ ls
src tmp
pureuser@1ddb0b0ed568:~$ cd src/
pureuser@1ddb0b0ed568:~/src$ ls
CONTRIBUTING.md README.md chapter11 chapter13 chapter2 chapter4 chapter6 chapter8
LICENSE.md chapter10 chapter12 chapter14 chapter3 chapter5 chapter7 chapter9
pureuser@1ddb0b0ed568:~/src$ cd chapter3/
pureuser@1ddb0b0ed568:~/src/chapter3$ bower install
pureuser@1ddb0b0ed568:~/src/chapter3$ pulp build
```
It should have built successfully. You can also run the tests:
```
pureuser@1ddb0b0ed568:~/src/chapter3$ pulp test
* Build successful.
* Running tests...
Nothing
Just ("Smith, John: 123 Fake St., Faketown, CA")
* Tests OK.
```
Since you mounted the volume, you can actually edit the code outside of the running docker instance and it will update inside the container!
Open up `chapter3/test/Main.purs` using your favorite editor, and update `example.address.street` in the `example` record to `"123 Foobar St."`. Now rerun the tests, and you'll see that it updated!
```
pureuser@1ddb0b0ed568:~/src/chapter3$ pulp test
* Build successful.
* Running tests...
Nothing
Just ("Smith, John: 123 Foobar St., Faketown, CA")
* Tests OK.
```
This docker image creates a user called `pureuser` that it logs in as so that `bower` and `pulp` don't yell at you. If you want to add more stuff as you go along, switch to the superuser (`su`), or add pureuser to sudoers.
