 ## [0.3.0](https://github.com/sbrow/envr/compare/v0.2.1...v0.3.0) (2026-06-16)
 
+Version 0.3.0 represents a significant departure (and improvement) for envr.
+The entire codebase was rewritten in [Odin](https://odin-lang.org/) (from Go).
+This reduced the binary size from over 17MB to under 600k, improved performance,
+and significantly reduced the number of project dependencies from 69 to just 2.

-# Table Rendering Memory Optimization Plan
-
-## Executive Summary
-
-This plan outlines improvements to eliminate excessive memory allocations and copies in the Odin table rendering system. The current implementation makes 10+ allocations per row, while the Zig equivalent makes zero allocations for rendering. This optimization will reduce memory usage, improve performance, and align with the project's efficiency goals.
-
-## Current State Analysis
-
-### Zig Version (Reference Implementation)
-- **Allocations**: 1 (data only)
-- **Data copies**: 0
-- **String allocation**: 0
-- **Column widths**: Stack array
-- **Output**: Direct to writer
-
-### Odin Version (Current Implementation)
-- **Allocations**: 10+ per row
-- **Data copies**: Multiple per row
-- **String allocation**: 2+ per row (concatenate + slice)
-- **Column widths**: Heap allocated
-- **Output**: Builder → stdout
-
-### Current Issues Identified
-
-1. **Table Infrastructure** (`table.odin`)
-   - Uses `strings.Builder` which allocates per-line memory
-   - Heap-allocated `[dynamic]int` for column widths
-   - Multiple `strings.concatenate()` calls creating new strings
-
-2. **Command Implementations**
-   - `cmd_list`: Creates intermediate `[]string` slices per row, allocates new strings via `strings.concatenate()`
-   - `cmd_sync`: Creates `SyncEntry` structs with cloned strings, allocates dynamic arrays
-   - `cmd_deps`: Allocates dynamic rows array unnecessarily
-
-3. **Memory Pattern**
-   - Each command allocates `[][]string` for table data
-   - Manual struct-to-row transformation creates copies
-   - Duplicate code across all table-using commands
-
-## Proposed Solutions
-
-### Phase 1: Core Table Infrastructure Overhaul
-
-#### 1.1 Direct Writer-Based Rendering
-**Current:**
-```odin
-b: strings.Builder
-strings.builder_init(&b)
-// ... build table in builder
-fmt.println(strings.to_string(b))
-```
-
-**Proposed:**
-```odin
-render_table :: proc(writer: io.Writer, headers: []string, rows: [][]string)
-```
-- Replace `strings.Builder` with `io.Writer` output
-- Eliminate intermediate string allocations
-- Write table components directly to output stream
-
-#### 1.2 Stack-Based Column Widths
-**Current:**
-```odin
-col_widths := make([dynamic]int, 0, len(headers))
-```
-
-**Proposed:**
-- Use fixed stack arrays for reasonable column counts
-- Implement small buffer optimization (SBO) for variable column counts
-- Only allocate for tables exceeding threshold (e.g., 16 columns)
-
-#### 1.3 Zero-Copy String Handling
-**Current:**
-```odin
-dir_str := strings.concatenate({row.Dir, "/"}, context.temp_allocator)
-```
-
-**Proposed:**
-- Replace `strings.concatenate()` with string slicing
-- Work directly with `EnvFile.Path` and `EnvFile.Dir` fields
-- Use `filepath.base()` and `filepath.dir()` without allocation where possible
-
-### Phase 2: Generic Table Interface
-
-#### 2.1 Field-Based Table Renderer
-```odin
-Table_Field :: struct {
-    name: string,
-    value: string,  // String view, no allocation
-    alignment: Alignment,
-}
-
-Table_Config :: struct {
-    writer: io.Writer,
-    fields: []Table_Field,
-    col_widths: []int,
-}
-
-render_row :: proc(cfg: Table_Config, row_data: any)
-```
-- Accept struct fields directly without intermediate arrays
-- Support field selection (show only specific fields)
-- Alignment options (left/center/right)
-
-#### 2.2 Field Extraction Procs
-- Generate field extraction helpers for each struct type
-- Avoid string allocation by returning string views
-- Cache computed values (like formatted status strings)
-
-#### 2.3 Streaming Table Processing
-- Process rows one at a time without collecting all rows
-- Reduce peak memory usage from O(N × strings) to O(table_structure)
-- Enable early termination if needed
-
-### Phase 3: Command-Specific Optimizations
-
-#### 3.1 Eliminate Intermediate Structs
-**Current (cmd_sync):**
-```odin
-for &file in files {
-    // ... processing
-    path_str, _ := strings.clone(file.Path)
-    status_str, _ := strings.clone(status)
-    append(&results, SyncEntry{Path = path_str, Status = status_str})
-}
-```
-
-**Proposed:**
-```odin
-for &file in files {
-    result, err_msg := db_sync(&db, &file)
-    // Direct rendering with zero-copy
-    render_sync_row(writer, file, result, err_msg)
-}
-```
-- `cmd_sync`: Work directly with `EnvFile` + `SyncFlagEnum`
-- `cmd_list`: Use `EnvFile` fields directly, no `ListEntry`
-- Generate table content on-the-fly
-
-#### 3.2 In-Place Status Computation
-```odin
-get_sync_status :: proc(result: SyncFlag, err_msg: string) -> string {
-    switch {
-    case .Error in result: return if len(err_msg) > 0 then err_msg else "error"
-    case .BackedUp in result: return "Backed Up"
-    case .Restored in result: return "Restored"
-    case .DirUpdated in result: return "Moved"
-    case: return "OK"
-    }
-}
-```
-- Compute status strings without allocation (use static lookup)
-- Cache formatted status values if needed
-- Reduce allocation count from N to 0 or 1
-
-#### 3.3 Batch Processing
-- Reduce allocation count by pooling small allocations
-- Use `context.temp_allocator` more effectively
-- Pre-allocate buffers for expected sizes
-
-### Phase 4: JSON Output Separation
-
-#### 4.1 Unified JSON Rendering
-```odin
-render_json_rows :: proc(writer: io.Writer, rows: any, field_names: []string)
-```
-- Create centralized JSON rendering helper
-- Work with same structs as table rendering
-- Use reflection or explicit field marshaling
-
-#### 4.2 Format-Agnostic Interface
-- Commands generate data → renderers handle format
-- Table renderer focuses only on ASCII/Unicode output
-- Keep terminal detection in command layer
-
-## Expected Improvements
-
-| Metric | Current | Target | Improvement |
-|--------|---------|--------|-------------|
-| **Allocations** | 10+ per row | 0-1 per table | 10x+ reduction |
-| **Memory copies** | 2-3 per row | 0 | 100% reduction |
-| **Peak memory** | O(N × strings) | O(table_structure) | Constant factor |
-| **Throughput** | Baseline | 2-3x faster | Performance boost |
-
-## Implementation Strategy
-
-### High-Priority Changes
-1. Replace `strings.Builder` with direct `io.Writer` output
-2. Convert column widths to stack-based allocation
-3. Eliminate intermediate struct allocations in commands
-
-### Medium-Priority Changes
-1. Create generic field-based table interface
-2. Implement streaming table processing
-3. Centralize JSON rendering logic
-
-### Low-Priority Changes
-1. Add alignment options beyond left-aligned
-2. Implement comprehensive field introspection
-3. Add advanced table formatting features
-
-## Tradeoff Questions
-
-Before implementation begins, we need to resolve these architectural questions:
-
-### 1. Generality vs. Performance
-**Question:** Should we create a fully generic table renderer (similar to Zig's `Table(T)`) or focus on optimizing the current 3 use cases first?
-
-**Options:**
-- **Generic approach**: Higher development cost, future-proof, may have some overhead
-- **Specific optimization**: Faster implementation, maximum performance for current use cases, less flexible
-
-**Recommendation:** Start with specific optimizations for current use cases, then generalize patterns that emerge.
-
-### 2. Alignment Support
-**Question:** Does the project need left/center/right alignment support, or is left-alignment sufficient?
-
-**Context:** Zig supports alignment options, but current Odin implementation only left-aligns. Most CLI tables work fine with left alignment.
-
-**Recommendation:** Start with left-alignment only, add alignment if specific use cases demand it.
-
-### 3. API Compatibility
-**Question:** Should we maintain the current `render_table()` API signature, or are breaking changes acceptable?
-
-**Current API:**
-```odin
-render_table :: proc(headers: []string, rows: [][]string)
-```
-
-**Options:**
-- **Maintain API**: Slower to implement, backward compatible, may need adapter layers
-- **Break API**: Faster implementation, cleaner code, requires updates to all callers
-
-**Recommendation:** Breaking changes are acceptable since this is an optimization-focused effort and callers are limited to 3 commands.
-
-### 4. Odin Capabilities
-**Question:** What runtime reflection or field introspection capabilities does Odin provide?
-
-**Context:** Zig uses `@typeInfo()` and comptime field iteration. We need to understand Odin's equivalent capabilities to design the optimal solution.
-
-**Recommendation:** Investigate Odin's runtime type information capabilities before finalizing the generic table interface design.
-
-### 5. Testing Strategy
-**Question:** Should we add comprehensive tests for new table rendering before optimizing commands, or optimize incrementally with tests added afterwards?
-
-**Options:**
-- **Test-first**: More robust, catches regressions early, slower initial development
-- **Optimize-first**: Faster development, may miss edge cases, requires retroactive testing
-
-**Recommendation:** Hybrid approach - add basic tests for core infrastructure, then optimize incrementally with additional tests for each command.
-
-## Next Steps
-
-1. **Research Phase**: Investigate Odin's type system and reflection capabilities
-2. **Prototype Phase**: Create minimal working prototype of zero-allocation table renderer
-3. **Refactor Phase**: Incrementally update commands to use new infrastructure
-4. **Test Phase**: Add comprehensive tests and verify memory improvements
-5. **Benchmark Phase**: Measure performance improvements and memory usage
-
-## Success Criteria
-
-- [ ] Zero allocations for table rendering (excluding initial data)
-- [ ] Zero string copies in the happy path
-- [ ] All 3 commands (`list`, `sync`, `deps`) use new infrastructure
-- [ ] Performance improvement of 2x or more
-- [ ] Memory usage reduction of 50% or more
-- [ ] No regression in table formatting quality
-- [ ] Backward compatibility with JSON output format

 # TODOs

-1. Consider giving db its own allocator
+2. Add color flag and support non colored output.
 
-2. **db.odin:324-327** — Map iteration (`remote_set`) is non-deterministic. Same file can produce different JSON on each backup, causing spurious DB diffs. Sort remotes before storing.
+3. Rewrite `write_command_help` to use text/tables
 
-3. **db.odin:135, 250** — String interpolation into SQL (`VACUUM INTO '%s'`, `ATTACH DATABASE '%s'`). Currently safe because input is controlled, but fragile.
+4. Generate md and man pages again.
 
-4. **features.odin:30-41** — `find_binary` uses `strings.join` instead of `filepath.join`, uses `os.stat` instead of checking executability, hardcodes `:` as PATH separator (wrong on Windows).
+5. Json may be an expensive encoding for remotes. Confirm with spall, and use null terminated strings if necessary.
 
-5. **cmd_restore.odin:20-30 & cmd_remove.odin:19-29** — Identical path-resolution block copy-pasted. `is_abs` guard is redundant since `filepath.abs` is a no-op on absolute paths. Extract a helper.
+6. Consistently ignore allocator errors
 
-6. **cmd_restore.odin:44** — `os.mkdir_all` error silently discarded. Subsequent write failure will be confusing.
+7. Check for prealloc opportunities. i.e. `make([dynamic]string)` -> `make([dynamic]string, 5)`.
 
-8. **config.odin:178** — `search_paths` silently ignores `os.user_home_dir` error. If home is empty, `~` isn't expanded. Same class of bug as issue 3.
+8. Add a text filter to the multi_select.
 
-10. **db.odin:115** — `json.unmarshal_string` error not checked. Malformed JSON silently produces empty/partial data.
+9. Add tests for untested commands.
 
-11. **db.odin:352-353** — `hex.encode` error ignored. `string(hex_bytes)` aliases the byte slice.
+10. add --format -f flag to commands that draw tables.
 
-12. **cmd_sync.odin:80, cmd_list.odin:33, cmd_deps.odin:9** — `make([]string, 2)` for table rows never freed. Leaks per row. Defer to memory pass.
+11. Replace `testing.expect` calls with `testing.expect_value` calls where appropriate.
 
-13. **cmd_list.odin** — Non-TTY branch builds `ListEntry` structs and marshals JSON separately. Now that `render_json_rows` (issue 1) accepts an `io.Writer` and uses `json.marshal`, unify both branches to use it. Note: will change JSON keys from `"directory"/"path"` to `"Directory"/"Path"`.
+12. procedures should be ordered by use, main at the top, then in the order they are called from main.
 
-14. Check for prealloc opportunities. i.e. `make([dynamic]string)` -> `make([dynamic]string, 5)`.
+13. Shell completion
 
-15. Add a text filter to the multi_select.
+14. Bring back windows support / cross-compilation.
 
-16. Create backup / fallback fd.
+15. Test all cmds / terminal branches.
 
-17. Add tests for untested commands.
+16. Fix error messages to use fmt.eprintf (stderr) instead of fmt.printf (stdout)
 
-18. 2 scan tests silently skip when fd isn't installed, tests pass without actually testing anything. These should use #assert to be sure that fd is in path.
+17. Pass allocator to findr?
 
-19. Try to do all encryption / decryption in memory - only read / write encrypted data to disk.

-# Windows Compatibility Guide
-
-This document outlines Windows compatibility issues and solutions for the envr project.
-
-## Critical Issues
-
-### 1. Path Handling Bug (MUST FIX)
-
-**File:** `app/env_file.go:209`
-
-**Issue:** Uses `path.Join` instead of `filepath.Join`, which won't work correctly on Windows due to different path separators.
-
-**Current code:**
-```go
-f.Path = path.Join(newDir, path.Base(f.Path))
-```
-
-**Fixed code:**
-```go
-f.Path = filepath.Join(newDir, filepath.Base(f.Path))
-```
-
-## External Dependencies
-
-The application relies on external tools that need to be installed separately on Windows:
-
-### Required Tools
-
-1. **fd** - Fast file finder
-   - Install via: `winget install sharkdp.fd` or `choco install fd`
-   - Alternative: `scoop install fd`
-
-2. **git** - Version control system
-   - Install via: `winget install Git.Git` or download from git-scm.com
-   - Usually already available on most development machines
-
-## Minor Compatibility Notes
-
-### File Permissions
-- Unix file permissions (`0755`, `0644`) are used throughout the codebase
-- These are safely ignored on Windows - no changes needed
-
-### Editor Configuration
-**File:** `cmd/edit_config.go:20-24`
-
-**Issue:** Relies on `$EDITOR` environment variable which is less common on Windows.
-
-**Current behavior:** Fails if `$EDITOR` is not set
-
-**Recommended improvement:** Add fallback detection for Windows editors:
-```go
-editor := os.Getenv("EDITOR")
-if editor == "" {
-    if runtime.GOOS == "windows" {
-        editor = "notepad.exe"  // or "code.exe" for VS Code
-    } else {
-        fmt.Println("Error: $EDITOR environment variable is not set")
-        return
-    }
-}
-```
-
-## Installation Instructions for Windows
-
-1. Install required dependencies:
-   ```powershell
-   winget install sharkdp.fd
-   winget install Git.Git
-   ```
-
-2. Fix the path handling bug in `app/env_file.go:209`
-
-3. Build and run as normal:
-   ```powershell
-   go build
-   .\envr.exe init
-   ```
-
-## Testing on Windows
-
-After applying the critical path fix, the core functionality should work correctly on Windows. The application has been designed with cross-platform compatibility in mind, using:
-
-- `filepath` package for path operations (mostly)
-- `os.UserHomeDir()` for home directory detection
-- Standard Go file operations
-
-## Summary
-
-- **1 critical bug** must be fixed for Windows compatibility
-- **2 external tools** need to be installed
-- **1 minor enhancement** recommended for better Windows UX
-- Overall architecture is Windows-compatible
