Add dot repeat, safer undo, leader passthrough, and V selection

[hamidi-dev]

Summary

• Add normal-mode . repeat for command-based changes like dw, dd, x, and r{char}
• Store vim change undo snapshots on a stack so repeated/count-based changes can be undone cleanly
• Pass through OpenCode leader sequences in normal/visual mode, including configured leaders and Tab
• Add V to select the current line and enter visual mode

Fixed

• dw.. now repeats the delete-word change
• u after dw.. walks back each repeated delete
• 3dw now restores in one undo step
• OpenCode leader bindings like <leader>e, <leader>l, and <leader>n are no longer swallowed by vimcode

Testing

• bun test
• bunx biome ci --error-on-warnings .

hey @hamidi-dev thx for the contribution. I prefer each PR to address a single specific issue, to allow easy rollback and troubleshooting. If possible, please split and send whatever you want out of this, and I will review and approve. Thanks!

I'm really looking forward for "Pass through OpenCode leader" feature/fix. If I can help, let me know. Right now, it's akin to tmux prefix would not work in vim normal mode.

[oribarilan]

@samuelmasuy it is already supported a few versions back :) please see
#21

LMK if you like it or find something missing please (you can reuse issue 21 or open a new one)

@oribarilan @samuelmasuy sorry i haven't gotten the time yet to address @oribarilan requests.
if the prefix issue is solved, thats great. i will work on the other topics of my PR.
or do you have an issue @samuelmasuy with prefix?
my original issue was using TAB as prefix.
I would have to test the v0.11.0 and see if that solves the TAB as prefix issue.

I should have been more precise: this is not working for me, unless I configured something incorrectly.
My leader in opencode is <C-x>, and I have the plugin configured like this:

[
  "vimcode@git+https://github.com/oribarilan/vimcode.git#v0.13.0",
  {
    "modeToast": false,
    "startMode": "normal",
    "leader": "C-x",
  },
]

When I’m in normal mode and press C-x-m (to list models), the m gets swallowed.
On this branch, though, the leader works from any mode, which is how I expected it to behave.

@samuelmasuy vimcode doesn't require you to configure it, it uses the leader key you already have configured.
It wasn't documented well so I added this section, you can read it and see how it goes now :)

I tried that too, here is a simple tui.json that reproduces for me:

{
  "$schema": "https://opencode.ai/tui.json",
  "keybinds": {
    "leader": "ctrl+x"
  },
  "plugin": [
    [
      "vimcode@git+https://github.com/oribarilan/vimcode.git#v0.13.0",
      {
        "modeToast": false,
        "startMode": "normal"
      }
    ]
  ]
}

<ctrl+x>m in normal mode does not popup the model selection. Note that not specifying any keybinds ALSO reproduces.
