README
# xontrib-langenv
[xonsh](https://xon.sh) integration with:
* [Pyenv](https://github.com/pyenv/pyenv)
* [Nodenv](https://github.com/nodenv/nodenv)
* [Goenv](https://github.com/syndbg/goenv)
* [Rbenv](https://github.com/rbenv/rbenv)
This xontrib replaces the slow `langenv` initialization with a faster python version (and skips the `rehash` step), which could save up to ~0.5s for each `lang`
The only two exceptions are:
- `goenv`, which requires an extra `rehash --only-manage-paths` [init step](https://github.com/syndbg/goenv/blob/e1007619dbb180c8f8032a9dcdb7afbeb88e848a/libexec/goenv-init#L167) to set some more [environment variables](https://github.com/syndbg/goenv/blob/e1007619dbb180c8f8032a9dcdb7afbeb88e848a/libexec/goenv-sh-rehash#L24)
- `virtualenv-init`
so if you rewrite that `goenv` env var setting and `pyenv` `virtualenv` init logic in python and xontribute to this xontrib, you could eliminate the last sources of xonsh langenv startup delay!
## Install
Install using pip
```
pip install xontrib-langenv
```
## Usage
Add to your `.xonshrc` as follows:
### Pyenv
```sh
xontrib load pyenv
```
This xontrib initializes `pyenv` when `xonsh` is started.
After initialization `pyenv` commands works as they would do in any *classic* shell.
Also supports [pyenv-virtualenv](https://github.com/pyenv/pyenv-virtualenv).
### Nodenv
```sh
xontrib load nodenv
```
This xontrib initializes `nodenv` when `xonsh` is started.
After initialization `nodenv` commands works as they would do in any *classic* shell.
### Goenv
```sh
xontrib load goenv
```
This xontrib initializes `goenv` when `xonsh` is started.
After initialization `goenv` commands works as they would do in any *classic* shell.
### Rbenv
```sh
xontrib load rbenv
```
This xontrib initializes `rbenv` when `xonsh` is started.
After initialization `rbenv` commands works as they would do in any *classic* shell.
## Compatibility notes
If you are using `xonsh` v0.11 (or older) and you have issues with the latest version of this xontrib, try to downgrade it to version 1.0.6.
