## [Unreleased]
|
|
|
|
## [0.5.0] - 2026-01-15
|
|
|
|
### Added
|
|
|
|
- **Cost Tracking System** - Track LLM API costs across sessions
|
|
- New `:CoderCost` command opens cost estimation floating window
|
|
- Session costs tracked in real-time
|
|
- All-time costs persisted in `.coder/cost_history.json`
|
|
- Per-model breakdown with token counts
|
|
- Pricing database for 50+ models (GPT-4/5, Claude, O-series, Gemini)
|
|
- Window keymaps: `q` close, `r` refresh, `c` clear session, `C` clear all
|
|
|
|
- **Automatic Ollama Fallback** - Graceful degradation when API limits hit
|
|
- Automatically switches to Ollama when Copilot rate limits exceeded
|
|
- Detects local Ollama availability before fallback
|
|
- Notifies user of provider switch
|
|
|
|
- **Enhanced Error Handling** - Better error messages for API failures
|
|
- Shows actual API response on parse errors (not generic "failed to parse")
|
|
- Improved rate limit detection and messaging
|
|
- Sanitized newlines in error notifications to prevent UI crashes
|
|
|
|
- **Agent Tools System Improvements**
|
|
- New `to_openai_format()` and `to_claude_format()` functions
|
|
- `get_definitions()` for generic tool access
|
|
- Fixed tool call argument serialization (JSON strings vs tables)
|
|
|
|
- **Credentials Management System** - Store API keys outside of config files
|
|
- New `:CoderAddApiKey` command for interactive credential setup
|
|
- `:CoderRemoveApiKey` to remove stored credentials
|
|
- `:CoderCredentials` to view credential status
|
|
- `:CoderSwitchProvider` to switch active LLM provider
|
|
- Credentials stored in `~/.local/share/nvim/codetyper/configuration.json`
|
|
- Priority: stored credentials > config > environment variables
|
|
- Supports all providers: Claude, OpenAI, Gemini, Copilot, Ollama
|
|
|
|
### Changed
|
|
|
|
- Cost window now shows both session and all-time statistics
|
|
- Improved agent prompt templates with correct tool names
|
|
- Better error context in LLM provider responses
|
|
|
|
### Fixed
|
|
|
|
- Fixed "Failed to parse Copilot response" error showing instead of actual error
|
|
- Fixed `nvim_buf_set_lines` crash from newlines in error messages
|
|
- Fixed `tools.definitions` nil error in agent initialization
|
|
- Fixed tool name mismatch in agent prompts (write_file vs write)
|

## [0.4.0] - 2026-01-13
|
|
|
|
### Added
|
|
|
|
- **Event-Driven Architecture** - Complete rewrite of prompt processing system
|
|
- Prompts are now treated as events with metadata (buffer state, priority, timestamps)
|
|
- New modules: `queue.lua`, `patch.lua`, `confidence.lua`, `worker.lua`, `scheduler.lua`
|
|
- Priority-based event queue with observer pattern
|
|
- Buffer snapshots for staleness detection
|
|
|
|
- **Optimistic Execution** - Ollama as fast local scout
|
|
- Use Ollama for first attempt (fast local inference)
|
|
- Automatically escalate to remote LLM if confidence is low
|
|
- Configurable escalation threshold (default: 0.7)
|
|
|
|
- **Confidence Scoring** - Response quality heuristics
|
|
- 5 weighted heuristics: length, uncertainty phrases, syntax completeness, repetition, truncation
|
|
- Scores range from 0.0-1.0
|
|
- Determines whether to escalate to more capable LLM
|
|
|
|
- **Staleness Detection** - Safe patch application
|
|
- Track `vim.b.changedtick` and content hash at prompt time
|
|
- Discard patches if buffer changed during generation
|
|
- Prevents stale code injection
|
|
|
|
- **Completion-Aware Injection** - No fighting with autocomplete
|
|
- Defer code injection while completion popup visible
|
|
- Works with native popup, nvim-cmp, and coq_nvim
|
|
- Configurable delay after popup closes (default: 100ms)
|
|
|
|
- **Tree-sitter Scope Resolution** - Smart context extraction
|
|
- Automatically resolves prompts to enclosing function/method/class
|
|
- Falls back to heuristics when Tree-sitter unavailable
|
|
- Scope types: function, method, class, block, file
|
|
|
|
- **Intent Detection** - Understands what you want
|
|
- Parses prompts to detect: complete, refactor, fix, add, document, test, optimize, explain
|
|
- Intent determines injection strategy (replace vs insert vs append)
|
|
- Priority adjustment based on intent type
|
|
|
|
- **Tag Precedence Rules** - Multiple tags handled cleanly
|
|
- First tag in scope wins (FIFO ordering)
|
|
- Later tags in same scope skipped with warning
|
|
- Different scopes process independently
|
|
|
|
### Configuration
|
|
|
|
New `scheduler` configuration block:
|
|
```lua
|
|
scheduler = {
|
|
enabled = true, -- Enable event-driven mode
|
|
ollama_scout = true, -- Use Ollama first
|
|
escalation_threshold = 0.7,
|
|
max_concurrent = 2,
|
|
completion_delay_ms = 100,
|
|
}
|
|
```
