# echodoc.vim

Displays function signatures from completions in the command line.

Installation

Use a package manager and follow its instructions.

Note: echodoc requires v:completed_item feature. It is added in Vim 7.4.774.

Global options

Flag	Default	Description
g:echodoc#enable_at_startup	0	If the value of this variable is non-zero, echodoc is automatically enabled at startup.
g:echodoc#type	"echo"	Where the documentation is displayed. Choose between: "echo", "signature", "virtual" or "floating"
g:echodoc#events	['CompleteDone']	If the autocmd-events are fired, echodoc is enabled.
g:g:echodoc#highlight_identifier	"Identifier"	The highlight of identifier.
g:echodoc#highlight_arguments	"Special"	The highlight of current argument.
g:echodoc#highlight_trailing	"Type"	The highlight of trailing.

Type "echo" Usage

When using

let g:echodoc#type = "echo" " Default value

The command line is used to display echodoc text. This means that you will
either need to set noshowmode or set cmdheight=2. Otherwise, the `--
INSERT -- mode text will overwrite echodoc`'s text.

When you accept a completion for a function with <c-y>, echodoc will
display the function signature in the command line and highlight the argument
position your cursor is in.

Examples

Option 1:

" To use echodoc, you must increase 'cmdheight' value.
set cmdheight=2
let g:echodoc_enable_at_startup = 1

Option 2:

" Or, you could disable showmode alltogether.
set noshowmode
let g:echodoc_enable_at_startup = 1

Option 3:

" Or, you could use neovim's virtual virtual text feature.
let g:echodoc#enable_at_startup = 1
let g:echodoc#type = 'virtual'

Option 4:

" Or, you could use neovim's floating text feature.
let g:echodoc#enable_at_startup = 1
let g:echodoc#type = 'floating'
" To use a custom highlight for the float window,
" change Pmenu to your highlight group
highlight link EchoDocFloat Pmenu

Option 5:

" Or, you could use vim's popup window feature.
let g:echodoc#enable_at_startup = 1
let g:echodoc#type = 'popup'
" To use a custom highlight for the popup window,
" change Pmenu to your highlight group
