# stacky

|

|
Personal template for the Stack build system based on Nix.
|
||||||
|
|
||||||

Based on the `new-template.hsfiles` from [stack-templates](https://github.com/commercialhaskell/stack-templates).
|

|
|
||||||

Create the project folder:
|

|
|
||||||
|
```
|
||||||
|
stack new <name> https://git.pbrinkmeier.de/paul/stacky/raw/branch/main/stacky.hsfiles
