This plugin provides basic support for .env and Procfile.
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.
With projectionist.vim and dispatch.vim 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.
If you call :Dispatch foreman run whatever or :Dispatch dotenv whatever,
the compiler will be correctly selected for the whatever command.
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
