@ -19,7 +19,7 @@ Nu draws inspiration from projects like PowerShell, functional programming langu
In Unix, it's common to pipe between commands to split up a sophisticated command over multiple steps. Nu takes this a step further and builds heavily on the idea of _pipelines_. Just as the Unix philosophy, Nu allows commands to output from stdout and read from stdin. Additionally, commands can output structured data (you can think of this as a third kind of stream). Commands that work in the pipeline fit into one of three categories
* Commands that produce a stream (eg, `ls`)
* Commands that filter a stream (eg, `where "file type" == "Directory"`)
* Commands that filter a stream (eg, `where type == "Directory"`)
* Commands that consumes the output of the pipeline (eg, `autoview`)
Commands are separated by the pipe symbol (`|`) to denote a pipeline flowing left to right.
@ -93,52 +93,13 @@ Finally, we can use commands outside of Nu once we have the data we want:
Here we use the variable `$it` to refer to the value being piped to the external command.
## Navigation
## Plugins
By default, Nu opens up into your filesystem and the current working directory. One way to think of this is a pair: the current object and the current path in the object. The filesystem is our first object, and the path is the cwd.
Nu supports plugins that offer additional functionality to the shell and follow the same object model that built-in commands use. This allows you to extend nu for your needs.
| object | path |
| ------ | ---- |
| Filesystem | /home/jonathan/Source/nushell |
There are a few examples in the `plugins` directory.
Using the `cd` command allows you to change the path from the current path to a new path, just as you might expect. Using `ls` allows you to view the contents of the filesystem at the current path (or at the path of your choosing).
In addition to `cd` and `ls`, we can `enter` an object. Entering an object makes it the current object to navigate (similar to the concept of mounting a filesystem in Unix systems).
```
/home/jonathan/Source/nushell(master)> enter Cargo.toml
object/>
```
As we enter, we create a stack of objects we're navigating:
| object | path |
| ------ | ---- |
| Filesystem | /home/jonathan/Source/nushell |
| object (from Cargo.toml) | / |
Commands `cd` and `ls` now work on the object being navigated.
```
object/> ls
-----------------+------------------+-----------------
dependencies | dev-dependencies | package
-----------------+------------------+-----------------
[object Object] | [object Object] | [object Object]
-----------------+------------------+-----------------
```
```
object/> cd package/version
object/package/version> ls
-------
value
-------
0.1.2
-------
```
The `exit` command will pop the stack and get us back to a previous object we were navigating.
Plugins are binaries that are available in your path and follow a "nu_plugin_*" naming convention. These binaries interact with nu via a simple JSON-RPC protocol where the command identifies itself and passes along its configuration, which then makes it available for use. If the plugin is a filter, data streams to it one element at a time, and it can stream data back in return via stdin/stdout. If the plugin is a sink, it is given the full vector of final data and is given free reign over stdin/stdout to use as it pleases.

* Nu views data as both structured and unstructured. It is an object shell like PowerShell.
These goals are all critical, project-defining priorities. Priority #1 is "direct compatibility" because any new shell absolutely needs a way to use existing executables in a direct and natural way.
* Finally, Nu views data functionally. Rather than using mutation, pipelines act as a mean to load, change, and save data without mutable state.
