vipsql

A vim-plugin for interacting with psql

Demo

Install

With Pathogen

$ cd ~/.vim/bundle && git clone https://github.com/martingms/vipsql

As a terminal command

To use vipsql in a manner similar to psql, add something like this to your .bashrc or similar:

vipsql() {
    vim -c 'setlocal buftype=nofile | setlocal ft=sql | VipsqlOpenSession '"$*"
}

All args are redirected to the psql session, so e.g.

$ vipsql -d test

will start vim with vipsql already connected to the database test.

Notes

Note that vipsql uses the vim channels feature, so your vim must be at least version 8, and compiled with +channel. To test whether you're compatible, run:

$ vim --version | grep -o +channel

If the output is +channel you should be good to go.

Please also note that sending an interrupt (SIGINT) to psql (for example to cancel a long running query) results in killing the channel in versions of vim older than 8.0.0588 due to a bug.

Neovim should be supported, but I have not had the chance to test it, so please let me know if you are a neovim user and can confirm. One thing that definitely does not work for neovim is to send SIGINT, as there doesn't seem to be any support for sending arbitrary signals through neovim's job api yet.

Configure

Bindings

Put the following in your .vimrc (and customize bindings to your liking):

" Starts an async psql job, prompting for the psql arguments.
" Also opens a scratch buffer where output from psql is directed.
noremap <leader>po :VipsqlOpenSession<CR>

" Terminates psql (happens automatically if the scratch buffer is closed).
noremap <silent> <leader>pk :VipsqlCloseSession<CR>

" In normal-mode, prompts for input to psql directly.
nnoremap <leader>ps :VipsqlShell<CR>

" In visual-mode, sends the selected text to psql.
vnoremap <leader>ps :VipsqlSendSelection<CR>

" Sends the selected _range_ to psql.
noremap <leader>pr :VipsqlSendRange<CR>

" Sends the current line to psql.
noremap <leader>pl :VipsqlSendCurrentLine<CR>

" Sends the entire current buffer to psql.
noremap <leader>pb :VipsqlSendBuffer<CR>

" Sends `SIGINT` (C-c) to the psql process.
noremap <leader>pc :VipsqlSendInterrupt<CR>

Options

Configuration options (and their defaults) are:

" Which command to run to get psql. Should be simply `psql` for most.
let g:vipsql_psql_cmd = "psql"

" The prompt to show when running `:VipsqlShell`
let g:vipsql_shell_prompt = "> "

" What `vim` command to use when opening the scratch buffer
let g:vipsql_new_buffer_cmd = "rightbelow split"

" Whether or not the vipsql-buffer should automatically scroll to the bottom
" on new input.
let g:vipsql_auto_scroll_enabled = 1

" Whether or not to print a separator in the output buffer when sending a new
" command/query to psql.
let g:vipsql_separator_enabled = 0

" What that separator should look like.
let g:vipsql_separator = '────────────────────'
