Installation

Using lazy.nvim

{
  "cargdev/codetyper.nvim",
  cmd = { "Coder", "CoderTransformSelection", "CoderModel" },
  keys = {
    { "<leader>ctt", desc = "Coder: Transform / Prompt" },
  },
  config = function()
    require("codetyper").setup({
      llm = {
        provider = "copilot", -- or "ollama"
      },
    })
  end,
}

Using packer.nvim

use {
  "cargdev/codetyper.nvim",
  config = function()
    require("codetyper").setup()
  end,
}

Quick Start

1. Select code in Visual mode and press <leader>ctt:

A floating prompt window opens.

2. Describe what you want:

add error handling and input validation

3. Press <CR> to submit — the LLM generates code inline.

4. Review the conflict and accept/reject:

  • ct — Accept AI suggestion (theirs)
  • co — Keep original code (ours)
  • cb — Accept both versions
  • cn — Delete both (none)

Configuration

require("codetyper").setup({
  llm = {
    provider = "copilot", -- Fallback when smart_selection is off: "copilot" or "ollama"
    smart_selection = true, -- Try Ollama first (free), escalate to Copilot on failure/low confidence

    copilot = {
      model = "claude-sonnet-4",
      ask_model = "gpt-5-mini", -- Cheaper model for explain/question calls
    },

    ollama = {
      host = "http://localhost:11434",
      model = "deepseek-coder:6.7b",
    },
  },
})

Credentials Management

Credentials are stored in ~/.local/share/nvim/codetyper/configuration.json.

:CoderCredentials       " View status
:CoderSwitchProvider    " Switch between Copilot and Ollama
:CoderModel             " Quick switch Copilot model

LLM Providers

GitHub Copilot

Uses your existing Copilot subscription via OAuth. Requires copilot.lua or copilot.vim.

llm = {
  provider = "copilot",
  copilot = { model = "claude-sonnet-4" },
}

Use :CoderModel to switch between Copilot models (gpt-4o, gpt-4.1, claude-sonnet-4, o4-mini, etc.).

Ollama (Local)

Run models locally with no API costs.

llm = {
  provider = "ollama",
  ollama = {
    host = "http://localhost:11434",
    model = "deepseek-coder:6.7b",
  },
}

Inline Transform

The core workflow. Select code and describe what you want.

Normal Mode (No Selection)

Press <leader>ctt — a prompt window opens. Describe what you want and code is inserted at the cursor line.

Visual Mode (With Selection)

Select code, press <leader>ctt — describe changes and the selected code is replaced with generated code.

Context Handling

The plugin uses Tree-sitter and indentation analysis to determine context:

  • Partial function selection: Enclosing function sent as context, only selected lines replaced
  • Whole function selected (>=85%): Injection range expanded to full function boundaries
  • Multiple functions: All affected functions included in context
  • Whole file selected (>=80%): Project tree sent as additional context
  • Explain/question prompts: Documentation inserted above the selection

Intent Detection

The plugin classifies your prompt to decide how code should be applied:

Intent Keywords Action
complete complete, finish, implement replace
refactor refactor, rewrite, simplify replace
fix fix, repair, debug, update, change replace
add add, create, insert, new, generate insert
document document, comment, jsdoc, annotate replace
test test, spec, unit test append
optimize optimize, performance, faster replace
explain explain, how this, what does, describe, overview explain window

Explain intent opens a right-side markdown panel with the explanation — it does not inject code into the buffer. Works with selection, cursor-in-function, or whole file.

Scope Resolution

Prompts and selections automatically resolve to their enclosing scope using Tree-sitter (with indentation fallback):

function getUserById(id: number): User | null {
  // Select this line and ask "add error handling"
  // → The full function is sent as context to the LLM
}

Scope types: function, method, class, block, file

Conflict Resolution

When code is generated, it is shown as a git-style conflict:

<<<<<<< CURRENT
// Original code here
=======
// AI-generated code here
>>>>>>> INCOMING
  • Green background: Original (CURRENT) code
  • Blue background: AI-generated (INCOMING) code
  • Virtual text: Shows available keymaps

After resolving a conflict, the menu automatically shows for the next one. Toggle auto-show with :CoderConflictAutoMenu.

Cost Tracking

Track LLM API costs across sessions:

:CoderCost
  • Session and all-time statistics
  • Per-model breakdown with token counts
  • Pricing for 50+ models
  • Savings tracking for free models (Ollama, Copilot free tier)
  • History persisted in .codetyper/cost_history.json
