|
|
|

|
|
Utility package for manipulating environment variables for [gopher-lua](https://github.com/yuin/gopher-lua)
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
```
|
||
|
|
go get github.com/kohkimakimoto/gluaenv
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
### `env.set(key, value)`
|
||
|
|
|
||
|
|
Same `os.setenv`
|
||
|
|
|
||
|
|
### `env.get(key)`
|
||
|
|
|
||
|
|
Same `os.getenv`
|
||
|
|
|
||
|
|
### `env.loadfile(file)`
|
||
|
|
|
||
|
|
Loads environment variables from a file. The file is as the following:
|
||
|
|
|
||
|
|
```
|
||
|
|
AAA=BBB
|
||
|
|
CCC=DDD
|
||
|
|
```
|
||
|
|
|
||
|
|
If this function fails, it returns `nil`, plus a string describing the error.
|
||
|
|
|
||
|
