## Haskell Setup
|
||
|
|
|
||
|
|
1. If you haven't already, [install Stack](https://haskell-lang.org/get-started)
|
||
|
|
* On POSIX systems, this is usually `curl -sSL https://get.haskellstack.org/ | sh`
|
||
|
|
2. Install the `yesod` command line tool: `stack install yesod-bin --install-ghc`
|
||
|
|
3. Build libraries: `stack build`
|
||
|
|
|
||
|
|
If you have trouble, refer to the [Yesod Quickstart guide](https://www.yesodweb.com/page/quickstart) for additional detail.
|
||
|
|
|
||
|
|
## Development
|
||
|
|
|
||
|
|
Start a development server with:
|
||
|
|
|
||
|
|
```
|
||
|
|
stack exec -- yesod devel
|
||
|
|
```
|
||
|
|
|
||
|
|
As your code changes, your site will be automatically recompiled and redeployed to localhost.
|
||
|
|
|
||
|
|
## Tests
|
||
|
|
|
||
|
|
```
|
||
|
|
stack test --flag dmfix:library-only --flag dmfix:dev
|
||
|
|
```
|
||
|
|
|
||
|
|
(Because `yesod devel` passes the `library-only` and `dev` flags, matching those flags means you don't need to recompile between tests and development, and it disables optimization to speed up your test compile times).
|
||
|
|
|
||
|
|
## Documentation
|
||
|
|
|
||
|
|
* Read the [Yesod Book](https://www.yesodweb.com/book) online for free
|
||
|
|
* Check [Stackage](http://stackage.org/) for documentation on the packages in your LTS Haskell version, or [search it using Hoogle](https://www.stackage.org/lts/hoogle?q=). Tip: Your LTS version is in your `stack.yaml` file.
|
||
|
|
* For local documentation, use:
|
||
|
|
* `stack haddock --open` to generate Haddock documentation for your dependencies, and open that documentation in a browser
|
||
|
|
* `stack hoogle <function, module or type signature>` to generate a Hoogle database and search for your query
|
||
|
|
* The [Yesod cookbook](https://github.com/yesodweb/yesod-cookbook) has sample code for various needs
|
||
|
|
|
||
|
|
## Getting Help
|
||
|
|
|
||
|
|
* Ask questions on [Stack Overflow, using the Yesod or Haskell tags](https://stackoverflow.com/questions/tagged/yesod+haskell)
|
||
|
|
* Ask the [Yesod Google Group](https://groups.google.com/forum/#!forum/yesodweb)
|
||
|
|
* There are several chatrooms you can ask for help:
|
||
|
|
* For IRC, try Freenode#yesod and Freenode#haskell
|
||
|
|
* [Functional Programming Slack](https://fpchat-invite.herokuapp.com/), in the #haskell, #haskell-beginners, or #yesod channels.
