 # Changelog
 
+## [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.
+
+### ⚠ BREAKING CHANGES
+
+* The encryption format of databases has changed. Age encryption is no longer supported, and no automatic migration path was implemented.
+
+### Features
+
+* All encryption/decryption now happens in-memory. ([fe2b256](https://github.com/sbrow/envr/commit/fe2b256bd61eaf551d53faf3893b473a64a94667))
+* Config can be loaded from any path with `--config-file (-c)` flag. ([4a26ee8](https://github.com/sbrow/envr/commit/4a26ee814591e6aab0eb99d2359d51b31011edfe))
+* Switched from age to libsodium. ([23b8c2d](https://github.com/sbrow/envr/commit/23b8c2dc671a23cf76cf6746b33806ded9381486))
+
+
+### Performance Improvements
+
+* Improved writer performance. ([365e914](https://github.com/sbrow/envr/commit/365e9149b1a738ac9119bb5f74dc7e047ecfed5b))

+# Test Coverage Plan
+
+## Current State
+
+- 104 tests, all passing
+- Strong coverage: crypto, ssh, db CRUD + env_file + update_dir, config save/load + paths, scan, features, cant_scan, parse_args, `-c`/`--config-file` flag
+- Misleading test files: `cmd_check_test`, `cmd_list_test`, `cmd_nushell_completion_test` don't test their namesake procs
+- Biggest remaining gap: all `cmd_*` handlers untested
+
+## Command handler tests
+
+Stdout will be captured by redirecting `os.stdout` to a pipe.
+
+### `cmd_version` (cmd_version.odin)
+- Test default output (prints VERSION)
+
+### `cmd_list` (cmd_list.odin)
+- Test TTY path: fixture DB with rows, capture table output
+- Test non-TTY path: capture JSON output, unmarshal and verify keys/values
+- Test empty DB: verify clean output (empty table or `[]`)
+
+### `cmd_backup` (cmd_backup.odin)
+- Test successful backup: valid path, verify `db_insert` called
+- Test missing file: verify error message
+- Test duplicate backup: verify rejection or update behavior
+
+### `cmd_remove` (cmd_remove.odin)
+- Test successful removal: existing entry, verify `db_delete` called
+- Test removal of non-existent entry: verify error or no-op
+
+### `cmd_restore` (cmd_restore.odin)
+- Test successful restore: entry exists in DB, verify file written to correct path
+- Test restore of missing entry: verify error
+- Test directory creation: restore to path with missing parent dirs
+
+## Hard to test (interactive / external deps)
+
+### `cmd_scan` (cmd_scan.odin)
+- Test with fixture git repo containing `.env` files
+- Test `find_unbacked` integration (already partially tested in `cmd_check_test.odin`)
+- Non-TTY JSON output path
+
+### `cmd_edit_config` (cmd_edit_config.odin)
+- Needs refactoring: extract `$EDITOR` parsing into testable helper (TODO 12)
+- Test multi-word editor values (`"code -w"`)
+- Test missing `$EDITOR`
+
+### `cmd_init` (cmd_init.odin)
+- Interactive prompt makes this hard
+- Needs refactoring: extract SSH key discovery and config generation into testable procs
+- Test `--force` flag behavior
+
+### `prompt.odin`
+- Needs refactoring to be testable
+- `render_options` could be tested if it accepted an `io.Writer`
+- `read_key` could be tested with a pipe/redirect instead of raw stdin
+- `multi_select` is end-to-end interactive, likely integration test only
+
+## Notes
+
+- DB integration tests should use in-memory SQLite (`:memory:`) where possible.
+- Temp dir fixtures should follow the pattern in `scan_test.odin`.
+- Tests that manipulate the `HOME` env var must use a mutex to prevent races with parallel test execution.

-# TODO

-Note: These todos can wait until all the subcommands have been ported.
+1. Bring back windows support / cross-compilation.
 
-## HIGH
+2. Commands are still leaking. (Write tests for everything first)
 
-2. **db.odin:380-383, 405, 446** — `sqlite.bind_text` return values overwritten but never checked. A failed bind means `sqlite.step` operates on unbound params.
+3. procedures should be ordered by use, main at the top, then in the order they are called from main.
 
-3. **config.odin:52-54** — `os.user_home_dir` error silently ignored. If it fails, `home` is `""` and all paths become relative (`".envr"` instead of `"~/.envr"`).
+4. Check for prealloc opportunities. i.e. `make([dynamic]string)` -> `make([dynamic]string, 5)`.
 
-## MEDIUM
+5. Test all cmds / terminal branches.
 
-4. **db.odin:29-35** — `make_temp_path` never calls `strings.builder_destroy`. Leaks builder buffer every call.
+6. Generate md and man pages again.
 
-5. **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.
+7. Shell completion
 
-6. **db.odin:470-473** — `string_to_cstring` allocates via `strings.clone_to_cstring` and never frees. Called dozens of times across db operations.
+8. Add tests for untested commands.
 
-7. **db.odin:470, 462** — Both `string_to_cstring` and `cstring_to_string` ignore allocation errors. A nil cstring gets passed to SQLite (UB).
+9. Update `read_wire_string` to use a slice.
 
-8. **db.odin:135, 250** — String interpolation into SQL (`VACUUM INTO '%s'`, `ATTACH DATABASE '%s'`). Currently safe because input is controlled, but fragile.
+10. Pass allocator to findr?
 
-9. **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).
+11. Smarter flag parsing?
 
-10. **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.
+12. Rewrite `write_command_help` to use text/tables
 
-11. **cmd_restore.odin:44** — `os.mkdir_all` error silently discarded. Subsequent write failure will be confusing.
+13. Instead of using a writer to strip colors, just don't print the colors.
 
-12. **cmd_edit_config.odin:27** — `$EDITOR` used as single binary name. Breaks for multi-word values like `"code -w"`. Needs `strings.fields()`.
+14. Add a text filter to the multi_select.
 
-33. **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.
+15. init -h doesn't show --force flag. Separate into multiple structs: Global_FLags, and Init_Flags?
 
-35. **prompt.odin:124** — `make([dynamic]bool, len(options))` creates N zero-initialized elements. Works because `false` is the default, but same footgun as original issue 1. Should be `make([dynamic]bool, 0, len(options))`.

-# 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
