**Work-in-progress, please take a look at [issues][2]**



A **feature-reduced** port of [GYP][0] to JavaScript (Node.js).



## Why?



* [GYP][0] is the only Python dependency of Node.js

* Python scripts have some contribution barrier for Node.js collaborators

* No generators other than `ninja` are actually required

* `node-gyp` implicitly depends on Python because of GYP. Porting it to

  `gyp.js` will remove extra dependency.



## Installation



```bash

npm install -g gyp.js

```



## Progress



Done:



* `gyp.input` - i.e. the "core" responsible for parsing `.gyp`/`.gypi` files,

  resolving conditions/variables, generating target build list

* `gyp.py` - parser/interpreter of reduced Python syntax



Kind-of working:



* `ninja` generator on Linux, OSX, FreeBSD, Windows (with Visual Studio)



TODO:



* https://github.com/indutny/gyp.js/issues



## Reduced Python



[GYP][0] conditions are written in Python. This project has no intention of

support of full Python syntax/runtime, thus only a limited subset was selected:



* Variable names

* Strings

* Numbers

* Unary operators: `not`

* Binary operators: `in`, `not in`, etc

* One method: `.split()`



Turns out this set is what is minimally required to be able to build Node.js

itself.
