 # 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))

 ## Current State
 
-- 63 tests, all passing (added 3 `render_table` tests)
+- 104 tests, all passing
-- Strong coverage: crypto (100%), ssh (80%), scan, features
+- Strong coverage: crypto, ssh, db CRUD + env_file + update_dir, config save/load + paths, scan, features, cant_scan, parse_args, `-c`/`--config-file` flag
-- `render_table` now takes `io.Writer` (Tier 1 item 1 done)
 - Misleading test files: `cmd_check_test`, `cmd_list_test`, `cmd_nushell_completion_test` don't test their namesake procs
-- Biggest gap: `db.odin` (15/21 procs untested), all `cmd_*` handlers untested, `parse_args` untested
+- Biggest remaining gap: all `cmd_*` handlers untested
 
-## Tier 1 — Easy wins (pure functions, minimal setup)
+## Command handler tests
 
-### 1. `render_table` (table.odin)
+Stdout will be captured by redirecting `os.stdout` to a pipe.
-- Follow existing `render_json_rows` test pattern
-- Test cases: normal data (verify box-drawing chars, column alignment), empty rows, wide unicode, single column
-- Assert against `strings.Builder` output
 
-### 2. `parse_args` (cli.odin) — BLOCKED: needs refactor
+### `cmd_version` (cmd_version.odin)
-- Reads `os.args` directly and calls `print_usage()`/`print_command_help()` as side effects
-- Cannot test without either accepting `[]string` param or extracting output
-- Minimal refactor: `parse_args(args: []string)` — caller passes `os.args`, tests pass synthetic slices
-- Return values (`ok`, `cmd.name`, `cmd.flags`, `cmd.bool_set`) are the interesting part to assert
-- Test cases: bare command, `--flag value`, `-f value`, positional args, `--help`/`-h`, unknown command, no args, mixed flags + positionals
-
-### 3. `is_encrypted_key` (ssh.odin)
-- Test cases: encrypted key (returns true), unencrypted key (returns false), RSA key, malformed key
-- Fills last gap in ssh.odin
-
-## Tier 2 — High value, medium effort (fixtures exist)
-
-### 4. `db.odin` CRUD layer
-Largest gap in the project. Infrastructure already in `db_integration_test.odin` (`fixture_key`, `fixture_db_path`, in-memory DB setup).
-
-Procs to test:
-- `db_open` / `db_close` — open in-memory DB, verify handle valid
-- `db_insert` — insert a row, verify it persists
-- `db_fetch` — fetch existing row, fetch missing row (returns false)
-- `db_delete` — delete existing row (returns true), delete missing row (returns false)
-- `db_list` — list multiple rows, empty DB
-- `db_vacuum_to_file` — vacuum to temp file, verify file exists and is non-empty
-
-Test pattern: create in-memory DB via `db_open`, insert fixture rows, query and assert, `defer db_close`.
-
-### 5. `load_config` / `save_config` (config.odin)
-- `save_config`: write a `Config` to temp dir, verify file exists and contents are valid JSON
-- `load_config`: read back a config written by `save_config`, round-trip assert
-- `load_config` error case: missing file returns error
-- Need a temp dir fixture (pattern exists in `scan_test.odin`)
-
-## Tier 3 — Command handlers (need DB + filesystem fixtures)
-
-### 6. `cmd_version` (cmd_version.odin)
 - Test default output (prints VERSION)
-- Test `--long`/`-l` flag output
-- Capture stdout, assert content
 
-### 7. `cmd_list` (cmd_list.odin)
+### `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 `[]`)
 
-### 8. `cmd_backup` (cmd_backup.odin)
+### `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
 
-### 9. `cmd_remove` (cmd_remove.odin)
+### `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
 
-### 10. `cmd_restore` (cmd_restore.odin)
+### `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

 ## Notes
 
-- All command handler tests will need stdout capture. Consider extracting a helper or using `io.Writer` injection.
 - DB integration tests should use in-memory SQLite (`:memory:`) where possible.
 - Temp dir fixtures should follow the pattern in `scan_test.odin`.
 - External dependency tests (`fd`, `git`) should use `#assert` to ensure the dependency is present rather than silently skipping (TODO 28).
+- Tests that manipulate the `HOME` env var must use a mutex to prevent races with parallel test execution.

-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. **db.odin:135, 250** — String interpolation into SQL (`VACUUM INTO '%s'`, `ATTACH DATABASE '%s'`). Currently safe because input is controlled, but fragile.
 
-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. **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).
 
-## MEDIUM
+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.
 
-4. **db.odin:29-35** — `make_temp_path` never calls `strings.builder_destroy`. Leaks builder buffer every call.
+6. **cmd_restore.odin:44** — `os.mkdir_all` error silently discarded. Subsequent write failure will be confusing.

+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.
 
-6. **db.odin:470-473** — `string_to_cstring` allocates via `strings.clone_to_cstring` and never frees. Called dozens of times across db operations.
+10. **db.odin:115** — `json.unmarshal_string` error not checked. Malformed JSON silently produces empty/partial data.
 
-7. **db.odin:470, 462** — Both `string_to_cstring` and `cstring_to_string` ignore allocation errors. A nil cstring gets passed to SQLite (UB).
+11. **db.odin:352-353** — `hex.encode` error ignored. `string(hex_bytes)` aliases the byte slice.
 
-8. **db.odin:135, 250** — String interpolation into SQL (`VACUUM INTO '%s'`, `ATTACH DATABASE '%s'`). Currently safe because input is controlled, but fragile.
+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.

+14. Check for prealloc opportunities. i.e. `make([dynamic]string)` -> `make([dynamic]string, 5)`.
 
-11. **cmd_restore.odin:44** — `os.mkdir_all` error silently discarded. Subsequent write failure will be confusing.
+15. Add a text filter to the multi_select.
 
-12. **cmd_edit_config.odin:27** — `$EDITOR` used as single binary name. Breaks for multi-word values like `"code -w"`. Needs `strings.fields()`.
+16. Create backup / fallback fd.
 
-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.
+17. Add tests for untested commands.
 
-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))`.
+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.
 
-39. Lots of memory leaks to fix.
+20. add --format -f flag to commands that draw tables.
 
-## LOW
+21. Replace `testing.expect` calls with `testing.expect_value` calls where appropriate.
 
-15. **db.odin:115** — `json.unmarshal_string` error not checked. Malformed JSON silently produces empty/partial data.
+22. Change struct field names from PascalCase to snake_case.
 
-16. **db.odin:352-353** — `hex.encode` error ignored. `string(hex_bytes)` aliases the byte slice.
+23. procedures should be ordered by use, main at the top, then in the order they are called from main.
