Configuration

Configure the plugin in tui.json:

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"enabled": true,
"toggle_key": "ctrl+shift+v",
"indicator": true,
"vim_enter_submit": false,
"vim_insert_after_submit": false,
"vim_system_clipboard_register": false
}
]
]
}

Options

For options beginning with vim_, the prefix may be omitted in plugin configuration.

Option	Purpose
enabled	Start with Vim mode enabled
vim_initial_mode	Start in insert (default) or normal mode
toggle_key	Keybind for Toggle vim mode
indicator	Show the prompt Vim indicator
vim_enter_submit	Submit with Enter from insert mode
vim_insert_after_submit	Return to insert mode after submit
vim_system_clipboard_register	Use the system clipboard as Vim register
vim_langmap	Map non-English keys or simple aliases
vim_normal_leader	Leader key for normal keybinds
normal_keybinds	Extra keybinds active only in Vim normal mode
keybinds["vim.normal"]	Nested normal-mode keybind configuration
vim_escape_sequence	Use a two-key escape sequence like jk

Note

Unsupported OCV options: vim_line_motions

Initial mode

Vim mode starts in insert mode by default. To start in normal mode instead, use:

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"enabled": true,
"vim_initial_mode": "normal"
}
]
]
}

Mode-scoped keybinds

Bind existing OpenCode commands only in Vim normal mode:

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"vim_normal_leader": "space",
"normal_keybinds": {
"<leader>s": "session.list",
"j": "session.line.down",
"k": "session.line.up"
}
}
]
]
}

normal_keybinds values can be command strings or objects:

{
"normal_keybinds": {
"j": {
"command": "session.line.down",
"desc": "Scroll down",
"preventDefault": false
}
}
}

Nested normal-mode keybind configuration is also accepted inside the plugin options:

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"keybinds": {
"vim.normal": {
"leader": "space",
"session_list": "<leader>s",
"messages_line_up": "<leader>k",
"messages_line_down": "<leader>j"
}
}
}
]
]
}

Submit behavior

By default, insert mode uses Enter for newlines and normal mode uses Enter to submit.

To submit from insert mode too:

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"vim_enter_submit": true
}
]
]
}

To always default to insert mode after a prompt submission:

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"vim_insert_after_submit": true
}
]
]
}

To keep newline available when vim_enter_submit is enabled, configure OpenCode's top-level input_newline keybind:

{
"keybinds": {
"input_newline": "alt+return"
}
}

Or configure a separate OpenCode submit key:

{
"keybinds": {
"prompt_submit": "alt+return"
}
}

input_newline and prompt_submit are OpenCode keybinds, not plugin options.

System clipboard register

Use the system clipboard as Vim's register:

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"vim_system_clipboard_register": true
}
]
]
}

Yank and delete operations sync to the system clipboard, p / P paste from it.

Note

Clipboard sync uses pbcopy / pbpaste on macOS, PowerShell clipboard commands on Windows, and wl-copy / wl-paste, xclip, or xsel on Linux.

Vim langmap

Map non-English keyboard layout characters to Vim command keys.

Keys and values should be single characters.

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"vim_langmap": {
"р": "h",
"о": "j",
"л": "k",
"д": "l"
}
}
]
]
}

Or for simple aliases:

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"vim_langmap": {
"H": "^",
"L": "$"
}
}
]
]
}

Vim escape sequence

Set a two-character sequence to leave insert mode without pressing Escape:

{
"plugin": [
[
"@leohenon/opencode-vim-plugin",
{
"vim_escape_sequence": "jk"
}
]
]
}
