# ChatGPT NeoVim Plugin (Extensively Updated with Step-by-Step Prompting)

This plugin integrates a ChatGPT O1 model workflow into Neovim. It allows you to:

1. Generate prompts containing:
   - An **initial prompt** (from `.chatgpt_config.yaml`)
   - A list of directories (also specified in `.chatgpt_config.yaml`) from which it gathers the project structure and file contents
   - **Interactive file selection** if enabled, so you can pick exactly which directories to include
   - Any **initial files** you define (e.g., `README.md`, etc.)

2. Copy these prompts to your clipboard to paste into ChatGPT O1.
3. Receive YAML changes from ChatGPT, then run `:ChatGPTPaste` to apply them or supply additional files.

## New Key Features

- **Step-by-Step Prompting** (`enable_step_by_step: true`):  
  If the request grows too large (exceeds `token_limit`), the plugin automatically generates a special prompt asking the model to split the task into smaller steps, working through them one by one. This approach helps you stay within the model’s maximum token limit without having to manually break things apart.

- **Partial Acceptance**: If `partial_acceptance: true`, you can open a buffer that lists the final changes. Remove or comment out lines you don’t want, then only those changes are applied.

- **Preview Changes**: If `preview_changes: true`, you get a buffer showing proposed changes before you apply them.

- **Interactive File Selection**: If `interactive_file_selection: true`, you choose which directories from `.chatgpt_config.yaml` get included in the prompt, reducing token usage.

- **Improved Debug**: If `improved_debug: true`, debug logs go into a dedicated `ChatGPT_Debug_Log` buffer for easier reading.

## Example `.chatgpt_config.yaml`

```yaml
project_name: "chatgpt_nvim"
default_prompt_blocks:
  - "basic-prompt"
  - "workflow-prompt"
directories:
  - "."
initial_files:
  - "README.md"
debug: false
enable_step_by_step: true
preview_changes: true
interactive_file_selection: true
partial_acceptance: true
improved_debug: true
token_limit: 3000
```

## Usage

1. **`:ChatGPT`**  
   - If `interactive_file_selection` is on, you’ll pick directories to include in a buffer named `ChatGPT_File_Selection`.
   - Save & close with `:wq`, `:x`, or `:bd` (you don’t have to use `:q`).
   - If `enable_step_by_step` is on and the prompt might exceed `token_limit`, the plugin will generate instructions prompting the model to address each step separately.

2. **Paste Prompt to ChatGPT**  
   - If the task is split into steps, simply copy/paste them one by one into ChatGPT.

3. **`:ChatGPTPaste`**  
   - The plugin reads the YAML from your clipboard. If it requests more files, it might again suggest a step-by-step approach.  
   - If final changes are provided:
     - Optionally preview them (`preview_changes`).  
     - Optionally partially accept them (`partial_acceptance`).  
     - Then the plugin writes/deletes files as specified.

## Troubleshooting & Tips
- Adjust `token_limit` in `.chatgpt_config.yaml` as needed.
- If partial acceptance is confusing, remember to remove or prepend `#` to lines you don’t want before saving and closing the buffer.
- If step-by-step prompting occurs, ensure you follow each prompt the model provides in the correct order.  
- Check `ChatGPT_Debug_Log` if `improved_debug` is on, or the Neovim messages if `debug` is on, for detailed info.
- You can close the selection or prompt buffers at any time with commands like `:bd`, `:x`, or `:wq`. No need to rely on `:q`.

## Debug Commands
If `enable_debug_commands` is true, you can include commands like these in your YAML:
```yaml
commands:
  - command: "list"
    dir: "some/directory"

  - command: "grep"
    pattern: "searchString"
    target: "path/to/file/or/directory"
```
The **list** command now uses the Linux `ls` command to list directory contents. The **grep** command searches for a given pattern in a file or all files in a directory.
