Simple tool to pipe a text into various cli tools. (psql, mysql, and so on)

First line in a buffer defines a command to execute (can contain a shebang).

<Plug>VialPipeExecute pipes current paragraph (a content between { and } marks) or visual selection

<Plug>VialPipeExecuteAll pipes whole buffer.

For example:

au FileType sql nmap <buffer> <leader><cr> <Plug>VialPipeExecute
au FileType sql vmap <buffer> <leader><cr> <Plug>VialPipeExecute

will map <leader><cr> to execute an expression under the cursor (or selected expression) in sql buffers.

And:

au FileType python nmap <buffer> <leader><cr> <Plug>VialPipeExecuteAll

will map <leader><cr> to execute python script.
