repld

Spawn an foregrounded psql repl that is also serving the repl on a unix domain socket:

> repld 'psql -U postgres'

Send input to it from another shell:

> repld-send <<< 'create table foo (bar int);'

vim

Example vim settings:

nn <silent> <Space>s m`vip<Esc>:silent '<,'>w !repld-send<CR>``
nn <silent> <Space>S m`:silent w !repld-send<CR>``
vn <silent> <Space>s m`<Esc>:silent '<,'>w !repld-send<CR>``

In normal mode, press Space-s to send the inner paragraph to the repld server, or Space-S to send the whole buffer.

In visual mode, press Space-s send the highlighted lines.
