# Hacking
|
|
|
|
## Getting the sources
|
|
|
|
Git is required to hack on anything, you can set up a git clone of GYP
|
|
as follows:
|
|
|
|
```
|
|
mkdir foo
|
|
cd foo
|
|
git clone git@github.com:nodejs/gyp-next.git
|
|
cd gyp
|
|
```
|
|
|
|
(this will clone gyp underneath it into `foo/gyp`.
|
|
`foo` can be any directory name you want. Once you've done that,
|
|
you can use the repo like anything other Git repo.
|
|
|
|
## Testing your change
|
|
|
|
GYP has a suite of tests which you can run with the provided test driver
|
|
to make sure your changes aren't breaking anything important.
|
|
|
|
You run the test driver with e.g.
|
|
|
|
``` sh
|
|
$ python -m pip install --upgrade pip setuptools
|
|
$ pip install --editable ".[dev]"
|
|
$ python -m pytest
|
|
```
|
|
|
|
See [Testing](Testing.md) for more details on the test framework.
|
|
|
|
Note that it can be handy to look at the project files output by the tests
|
|
to diagnose problems. The easiest way to do that is by kindly asking the
|
|
test driver to leave the temporary directories it creates in-place.
|
|
This is done by setting the enviroment variable "PRESERVE", e.g.
|
|
|
|
```
|
|
set PRESERVE=all # On Windows
|
|
export PRESERVE=all # On saner platforms.
|
|
```
|
|
|
|
## Reviewing your change
|
|
|
|
All changes to GYP must be code reviewed before submission.
