Unreleased

0.6.0 - 2026-01-16

Added

• Conflict Resolution System - Git-style diff visualization for code review

  • Floating menu with cm or <CR> on conflict
  • Number keys 1-4 for quick selection in menu
  • Auto-show menu after code injection
  • Auto-show menu for next conflict after resolution
  • Commands: :CoderConflictToggle, :CoderConflictMenu, :CoderConflictNext, :CoderConflictPrev, :CoderConflictStatus, :CoderConflictResolveAll, :CoderConflictAcceptCurrent, :CoderConflictAcceptIncoming, :CoderConflictAcceptBoth, :CoderConflictAcceptNone, :CoderConflictAutoMenu

• Linter Validation System - Auto-check and fix lint errors after code injection

  • New linter.lua module for LSP diagnostics integration
  • Auto-saves file after code injection
  • Waits for LSP diagnostics to update
  • Detects errors and warnings in injected code region
  • Auto-queues AI fix prompts for lint errors
  • Shows errors in quickfix list
  • Commands: :CoderLintCheck, :CoderLintFix, :CoderLintQuickfix, :CoderLintToggleAuto

• SEARCH/REPLACE Block System - Reliable code editing with fuzzy matching

  • New search_replace.lua module for reliable code editing
  • Parses SEARCH/REPLACE blocks from LLM responses
  • Fuzzy matching with configurable thresholds
  • Whitespace normalization for better matching
  • Multiple matching strategies: exact, normalized, line-by-line
  • Automatic fallback to line-based injection

• Process and Show Menu Function - Streamlined conflict handling

  • New process_and_show_menu() function combines processing and menu display
  • Ensures highlights and keymaps are set up before showing menu

Changed

• Unified automatic and manual tag processing to use same code path
• insert_conflict() now only inserts markers, callers handle processing
• Added nowait = true to conflict keymaps to prevent delay from built-in c command
• Improved patch application flow with conflict mode integration

Fixed

• Fixed string.gsub returning two values causing table.insert errors
• Fixed keymaps not triggering due to Neovim's c command intercepting first character
• Fixed menu not showing after code injection
• Fixed diff highlighting not appearing

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
  • Improved rate limit detection and messaging
  • Sanitized newlines in error notifications

• Agent Tools System Improvements

  • New to_openai_format() and to_claude_format() functions
  • get_definitions() for generic tool access
  • Fixed tool call argument serialization

• 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

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

0.4.0 - 2026-01-13

Added

• Event-Driven Architecture - Complete rewrite of prompt processing system

  • Prompts are now treated as events with metadata
  • 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, syntax, 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

• Completion-Aware Injection - No fighting with autocomplete

  • Defer code injection while completion popup visible
  • Works with native popup, nvim-cmp, and coq_nvim

• Tree-sitter Scope Resolution - Smart context extraction

  • Automatically resolves prompts to enclosing function/method/class
  • Falls back to heuristics when Tree-sitter unavailable

• Intent Detection - Understands what you want

  • Parses prompts to detect: complete, refactor, fix, add, document, test, optimize, explain
  • Intent determines injection strategy

Configuration

New scheduler configuration block:

scheduler = {
  enabled = true,
  ollama_scout = true,
  escalation_threshold = 0.7,
  max_concurrent = 2,
  completion_delay_ms = 100,
}
