## Database Setup # Start9 Registry/Publish
After installing Postgres, run: This codebase is the reference implementation of the marketplace protocol.
``` ## Getting Started
createuser start9-registry --pwprompt --superuser
# Enter password start9-registry when prompted
createdb start9-registry
createdb start9-registry_test
```
## Haskell Setup ### Installing Haskell
1. If you haven't already, [install Stack](https://haskell-lang.org/get-started) - Go get [GHCup](https://www.haskell.org/ghcup/)
* On POSIX systems, this is usually `curl -sSL https://get.haskellstack.org/ | sh` - run `ghcup tui`
2. Install the `yesod` command line tool: `stack install yesod-bin --install-ghc` - select the latest `Stack` and install with `i`
3. Build libraries: `stack build`
If you have trouble, refer to the [Yesod Quickstart guide](https://www.yesodweb.com/page/quickstart) for additional detail. ### Build the Registry
## Development - `apt install libpq-dev`
- run `make`
Start a development server with: ### Set up embassy-publish tool
``` - run `stack install embassy-publish`
stack exec -- yesod devel - run `embassy-publish init --bash` (or --zsh / --fish depending on your preferred shell)
``` - run `embassy-publish reg add -l <URL> -n <NAME> -u <USER> -p <PASS>`
- take the hash that is emitted by this command and submit it to the registry owner
As your code changes, your site will be automatically recompiled and redeployed to localhost. ### Setting up a registry dev environment
### Development tools - set up a local database in postgresql
- set the PG_DATABASE environment variable to that database
- set PG_USER to the owner of that database
- set PG_PASSWORD to the password for that user
- set SSL_AUTO to false
- set RESOURCES_PATH to an empty directory you wish to use as your package repository
- install `embassy-sdk`
- set STATIC_BIN to the path that contains `embassy-sdk`
`ghcid "-c=stack ghci --test"` ## APIs
- Clone [HIE](https://github.com/haskell/haskell-ide-engine) ### EOS
- Checkout latest reslease ie. `git checkout tags/1.3`
- Follow github instructions to install for specific GHC version ie. `stack ./install.hs hie`
- Install VSCode Haskell Language Server Extension
To create `hie.yaml` if it does not exist: This API is exclusive to Start9, we do not publish this as part of the standard Marketplace protocol because Start9 does
- gather executables by running `stack ide targets` not intend for other organizations to host prebuilt OS binaries per the Non Commercial License
- see [here](https://github.com/haskell/haskell-ide-engine#project-configuration) for file setup details
## Tests ### Package
``` This API is a public API that can be implemented by any marketplace. This is how information about available packages
stack test --flag start9-registry:library-only --flag start9-registry:dev and their relationships is queried by EOS.
```
(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). ### Admin
## Builds This API is how we upload new packages to the marketplace. It requires authentication and is not intended to be implemented
by other marketplaces
`make`
### Tests with HIE Setup
- install hspec-discover globally `cabal install hspec-discover` (requires cabal installation)
- Current [issue](https://github.com/haskell/haskell-ide-engine/issues/1564) open for error pertaining to obtaining flags for test files
- recommended to setup hie.yaml
- recommended to run `stack build --test --no-run-tests` *before* any test files are open and that test files compile without error
- helps to debug a specific file: `hie --debug test/Main.hs`
## 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.
