## Interactive Usage
Use `:Dotenv {file}` or `:Dotenv {dir}` to load a `.env` file and set the corresponding environment variables in Vim. Use `:verbose Dotenv` to see what variables are actually being set.
## Projections
With projectionist.vim (vimscript #4989) and dispatch.vim (vimscript #4504) installed, you'll get a default `:Start` of `foreman start` for projects with a `Procfile`, and a default `:Dispatch` of `foreman check` for the `Procfile` itself.
## Dispatch
If you call `:Dispatch foreman run whatever` or `:Dispatch dotenv whatever`, the compiler will be correctly selected for the `whatever` command.
## API
While the above are all marginally helpful, this is the use case that inspired the plugin. Other plugins can call `DotenvGet('VAR')` to get the value of `$VAR` globally or from the current buffer's `.env`. Here's a wrapper to optionally use `DotenvGet()` if it's available.
function! s:env(var) abort
return exists('*DotenvGet') ? DotenvGet(a:var) : eval('$'.a:var)
endfunction
let db_url = s:env('DATABASE_URL')
There's also `DotenvExpand()`, a drop-in replacement for `expand()`.
function! s:expand(expr) abort
return exists('*DotenvExpand') ? DotenvExpand(a:expr) : expand(a:expr)
endfunction |
