Vim command mode complete word

tab completionvim

Is there a way to get Vim in command mode to complete words from the current file? Say I have this file:

one
two
three
once

and I enter command line mode

:myruncommand o|

where | denotes the cursor position. How do I make Vim complete one or once when pressing Tab?

It's not possible natively, but it took about one minute to find this script and this one on vim.org.

Use regular expressions:

/\<your_exact_word\>

In other words, enclose your search string between \< and \>

Map ) to skip over the exisiting ) if it is a closing parenthesis

inoremap <expr> )  strpart(getline('.'), col('.')-1, 1) == ")" ? "\<Right>" : ")"

:h i_CTRL-O execute one command, return to Insert mode.

Ctrl-ol will move you one character to the right then return you to insert mode.

Alternatively some of the bracket plugins allow you to just type the closing bracket ) and they will override the existing one.
