# capp_env | ||
|
||
`capp_env` is a simple virtual environment tool for Cappuccino. | ||
|
||
|
||
## Usage | ||
|
||
To create a virtual environment: | ||
|
||
capp_env -p /path/to/the/env | ||
|
||
This will create | ||
|
||
/path/to/the/env | ||
/bin | ||
/build | ||
/sources # if you want to put your sources here, but it is optional | ||
/narwhal | ||
|
||
It will download the latest `cappuccino_base`, put it in `narwhal` and will create an `activate` file in `/path/to/the/env/bin` | ||
|
||
Then you can activate this environment by doing: | ||
|
||
source /path/to/the/env/bin/activate | ||
|
||
your current `PATH` will be updated to look for `jake` and `capp` and all the tools from `/path/to/the/env/narwhal/bin`, and will set `CAPP_BUILD` to be `/path/to/the/env/build`. | ||
|
||
From now on, you can clone the Cappuccino sources, (in `sources` for instance) and do | ||
|
||
jake install | ||
|
||
If you install the Cappuccino source while in an virtual env, all the tools will use the debug version that you just built (for instance, `nib2cib` will be used from `/path/to/the/env/build/Debug/CommonJS/cappuccino/bin/nib2cib`) | ||
|
||
|
||
## Deactivate | ||
|
||
Just close the current terminal, or run | ||
|
||
deactivate | ||
|
||
|
||
## TODOs | ||
|
||
- let a chance to select the current cappuccino base version to download | ||
- find a way to make XcodeCapp to use these environements |
