(`{{{ .PackageName }}}` for example) - -Packman uses a simple approach to render your project, at first packman will run your **Activation Script**, your **Activation Script** is responsible for creating a data model that represents your project. -*Then*, packman will go through your project tree rendering each file using Go's template engine and the data model provided by your **Activation Script**, and ... That's it! - -Let's examine the simplest form of an **Activation Script** -```go -package main - -import ( - "os" - pm "github.com/securenative/packman/pkg" -) - -type MyData struct { - PackageName string - ProjectPath string - Flags map[string]string -} - -func main() { - // Parse the flags being forwarded from packman commands: - // This is how we can use custom flags - flags := pm.ParseFlags(os.Args[2:]) - - /** - YOUR CUSTOM LOGIC - **/ - - // The next step is to build our data model, the data model will be used by - // the template directives. - model := MyData{ - PackageName: flags[pm.PackageNameFlag], // Here we can see that {{{ .PackageName }}} refers to this field - ProjectPath: flags[pm.PackagePathFlag], - Flags: flags, - } - - // You must reply your data model back to the packman's driver - pm.Reply(model) -} -``` - -These concepts makes `packman` simple enough to understand but powerful enough to generate any kind of project. -## API - -### New Project -You can use packman to create a basic seed project which contains the basic structure of a packman template. -```bash -packman init -``` - -### Render -As the **Template Project** grows you'll need a way to quickly check that your project is rendered correctly, -The render will take the path of your **Template Project** and the path to the rendered output and any custom flags you wish to forward to your **Activation Script**. -```bash -packman render -customflag1 value1 -customflag2 value2 ... -``` - -## Unpack -Unpack is the "wet" version of render, the only difference is that unpack will pull a template from the remote storage instead of you local file system. -```bash -packman unpack -customflag1 value1 -customflag2 value2 ... -``` - -## Pack -Pack will take a **Template Project** and will push it to the remote storage so others can use it. -```bash -packman pack -``` - -## Configuration -Packman supports local persistent kv-storage so you can store any kind of configurations with it, but currently only github configuration is supported. -```bash -packman config github --username --token [--private] -``` -The `--private` flag will indicate that we will pack the template as a private github repository instead of a public one. diff --git a/cmd/packman/controllers/configure.go b/cmd/packman/controllers/configure.go deleted file mode 100644 index
