#### What's new
##### v1.1
- [ ] Windows support - **Moved to 1.2**
- [x] Custom paths for the commands fast/add
- [x] Save output on a file
- [x] Enable the fields Before/After
- [x] Web panel (localhost:5000)

--name="Project Name" -> Name, if not specified takes the working directory name
--path="server" -> Base Path, if not specified takes the working directory name
--path="server" -> Custom Path, if not specified takes the working directory name
--build -> Enables the build
--test -> Enables the tests
--test -> Enables the tests
--no-bin -> Disables the installation
--no-run -> Disables the run
--no-fmt -> Disables the fmt (go fmt)
--no-server -> Disables the web panel (port :5000)

Examples:
```
$ realize add
```
```
$ realize add --path="mypath"
```
```
$ realize add --name="My Project" --build
```
```
$ realize add --name="My Project" --path="/projects/package" --build

$ realize add --path="/Users/alessio/go/src/github.com/tockins/realize-examples/coin/"
```
If you want, you can specify additional arguments for your project.

The fast command supports the following custom parameters:
```
--path="server" -> Custom Path, if not specified takes the working directory name
--build -> Enables the build

--config -> Take the defined settings if exist a config file
--no-bin -> Disables the installation
