This is tool for creating completely configured production Haskell projects.
## Demo
[](https://asciinema.org/a/PCt492vIY7ccuNw3qBJFM9q9G)
## Getting started
### Prerequisites
To start using it make sure you have next tools installed on your machine:
* [`Stack`](http://haskellstack.org) or [`cabal`](https://www.haskell.org/cabal/)
* [`git`](https://git-scm.com)
* [`hub`](https://github.com/github/hub)
### Installation
Installation process can be done with one simple command:
$ cabal install summoner
or
$ stack install summoner --resolver nightly-2018-06-14
You can turn on the bash auto-completion by running the following command:
```
$ source <(summon --bash-completion-script `which summon`)
```
After that you can call `summon` with required command line options, follow
the instructions that will appear, and a new project would be created in a subfolder
as well as a repository under your github account (if requested).
### Usage
There are several options how to set particular configurations:
1. Default configuration file (`~/.summoner.toml`).
2. Explicitly specified configuration file by `--file FILENAME` option (used instead of default one if specified).
3. Options that are stated by CLI arguments.
4. Interactively inputed answers during work of the `summon` command
(for the options that were not specified on previous steps).
So the configuration uses [`Partial Options Monoid Pattern`](https://medium.com/@jonathangfischoff/the-partial-options-monoid-pattern-31914a71fc67).
If none of the mentioned above cases used then the configuration will be built interactively.
#### Configurations
##### `.toml` files:
Here is the list of the options that could be configured for your needs:
###### Global keys
* `owner` – `GitHub` login.
* `fullName` – full name.
* `email` – e-mail address.
* `license` – license (possible options: `MIT`, `BSD2`, `BSD3`, `GPL-2`, `GPL-3`,
`LGPL-2.1`, `LGPL-3`, `AGPL-3`, `Apache-2.0`, `MPL-2.0`).
* `ghcVersions` – `summoner` uses default `GHC-8.2.2`. But additionally you can specify other versions.
For each version `x.y.z` the `stack-x.y.z.yaml` will be created.
* `github` – `true` if you want to turn on `GitHub` integration by default,
`false` if you don't. If not specified it would be asked during each run of the `summoner`.
* `travis` – `true` if you want to turn on `Travis` integration by default,
`false` if you don't. Ignored if `github = false`.
If not specified it would be asked during each run of the `summoner`.
* `appveyor` – `true` if you want to turn on `AppVeyor` integration by default,
`false` if you don't. Ignored if `github = false`.
If not specified it would be asked during each run of the `summoner`.
* `private` – `true` if you want to create private repositories by default,
`false` if you don't. Ignored if `github = false`.
If not specified it would be asked during each run of the `summoner`.
* `bscript` – `true` if you want to include [build script](#build-script) by default,
`false` if you don't. If not specified it would be asked during each run of the `summoner`.
* `lib` – `true` if you want to create `src` folder with dummy `Lib.hs` file and library target by default,
`false` if you don't. If not specified it would be asked during each run of the `summoner`.
* `exe` – `true` if you want to create `app` folder with dummy `Main.hs` file and executable target by default,
`false` if you don't. If not specified it would be asked during each run of the `summoner`.
* `test` – `true` if you want to create `test` folder with dummy `Spec.hs` file and test target by default,
`false` if you don't. If not specified it would be asked during each run of the `summoner`.
* `bench` – `true` if you want to create `benchmark` folder with `Main.hs` file with [`gauge`](https://hackage.haskell.org/package/gauge) library usage example by default,
`false` if you don't. If not specified it would be asked during each run of the `summoner`.
* `extensions` – List of the default extensions to add into `default-extensions` section in the `.cabal`.
###### Custom prelude options
Should be specified inside `[prelude]` table.
* `package` – Name of the package of the custom prelude you'd like to use in the project (doesn't work without `module` field).
* `module` – Name of the module of the custom prelude you'd like to use in the project (doesn't work without `package` field).
###### Examples
See example of [configuration for projects of `Kowainik` organization](https://github.com/kowainik/org/blob/master/.summoner.toml).
By default the `summoner` will look for the configuration file (`.summoner.toml`) in home directory.
The other way to specify some particular `.toml` file is `summon PROJECTNAME --file FILEPATH` command.
##### CLI
See the basic usage syntax below (you can check it out with `summon --help` command):
```
summon PROJECT_NAME [with [OPTIONS]] [without [OPTIONS]]
[-f|--file FILENAME] [--prelude-package PACKAGE_NAME]
[--prelude-module MODULE_NAME]
Available global options:
-h, --help Show this help text
-v, --version Show summoner's version
-f, --file FILENAME Path to the toml file with configurations. If not
specified '~/.summoner.toml' will be used if present
--prelude-package PACKAGE_NAME
Name for the package of the custom prelude to use in
the project
--prelude-module MODULE_NAME
Name for the module of the custom prelude to use in
the project
Available commands:
with Specify options to enable
without Specify options to disable
Available command options:
-h,--help Show this help text
-g, --github Github integration
-p, --private Create private GitHub repository
-c, --travis Travis CI integration
-w, --app-veyor AppVeyor CI integration
-s, --script Build script
-l, --library Library target
-e, --exec Executable target
-t, --test Tests
-b, --benchmark Benchmarks
```
The options to be enabled/disabled can be specified while running the command.
If any of applicable command options wasn't tagged as enabled/disabled then
the question will be asked during the work of the script.
For example,
```
summon newProject with -letgcspw without -b --prelude-package universum --prelude-module Universum
```
will create fully functional project which uses custom prelude `universum`, contains
library, executable file, tests, [build script](#build-script)
and create private repository on [github](https://github.com)
integrated with `Travis-CI`, `AppVeyor-CI`, but benchmarks won't be attached to this one.
But when calling this command
```
summon newProject
```
the tool will ask about every particular option, rather you'd like to have it
or not in your project.
### Note
This tool was tested with next settings:
stack version 1.6.1
git version 2.11.0
hub version 2.2.9
## Features
If you're running the `summoner` with all options enabled a project with the following
hierarchy will be created:
```
project-name
├── app
│ └── Main.hs
├── benchmark
│ └── Main.hs
├── src
│ ├── ProjectName.hs
│ └── Prelude.hs
├── test
│ └── Spec.hs
├── CHANGELOG.md
├── LICENSE
├── project-name.cabal
├── README.md
├── Setup.hs
├── stack.yaml
├── appveyor.yml
├── .git
├── .gitignore
└── .travis.yml
```
and also repository with one commit at master will be added with enabled `Travis-CI` for that.
### Build script
The `b` script builds the project in a way that is convenient for developers.
It passes the right flags into right places, builds the project with --fast,
tidies up and highlights error messages in GHC output.
#### Usage
```
./b build whole project with all targets
./b -c do stack clean
./b -t build and run tests
./b -b build and run benchmarks
./b --nix use nix to build package
```

## Acknowledgments
This project was inspired by [Aelve/new-hs](https://github.com/aelve/new-hs#readme),
which is the tool with the same goal but it's using
[`cabal`](https://www.haskell.org/cabal/) for creating projects.
